Why can two young and healthy individuals be affected so differently by coronavirus? – Health24

Posted: May 16, 2020 at 11:48 am

New information about the new coronavirus (SARS-CoV-2) is constantly emerging, which is critical in the race to develop a vaccine and treatment for Covid-19. In a recent discovery, scientists found that a patients genes may provide clarity on why one young, healthy individual can be almost unaffected by the virus, while another can become seriously ill and end up in the intensive care unit (ICU).

In looking for rare, silent (hidden) gene mutations that are triggered by the virus, researchers are hoping it will take them one step closer to potential treatments.

At risk: Not just older people with underlying illnesses

Its agreed that the Covid-19 virus causes severe disease and kills older people with chronic illness; those with underlying medical conditions such as diabetes and lung disease; and men, at a greater rate than young people.

However, in an unexpected twist, were seeing a minority of patients who are under 50 take up space in ICUs around the world as well without any underlying medical conditions.

Speaking to AFP, and quoted in aScienceAlert article, geneticist Jean-Laurent Casanova director of the human genetics of infectious diseases laboratory jointly based at the Imagine Institute in Paris and Rockefeller University in New York revealed thatthis amounts to roughly five percent of patients:"Someone who could have run the marathon in October 2019, and yet in April 2020 is in intensive care, intubated and ventilated."

Casanovas goal is to find out if these patients may possibly have rare genetic mutations. "The assumption is that these patients have genetic variations that are silent until the virus is encountered," he explained.

The geneticist also co-founded the Covid Human Genetics Effort, which will analyse the genome of younger Covid-19 patients with severe illness in China and Europe, and also hopes to find out why certain people do not become infected, in spite of repeated exposure.

Earlier this month, HealthDay reported on this international study, led by Casanova. It will enrol 500 patients under the age of 50 with no underlying health conditions, and who have been diagnosed with Covid-19 and admitted to ICU.

Gene mutations can also offer protection

Gene mutations may be given a bad rap for making certain people more susceptible to a number of viral infectious diseases, such as influenza, but there is also a positive side.

According to ScienceAlert, researchers found a particularly rare mutation of a single gene, named CCR5, in the 1990s. This mutation actually offered protection against disease in that it stopped people from contracting HIV, laying the foundation for the development of treatments.

How may this help in Covid-19 treatment?

Mark Daly, director of the Institute for Molecular Medicine Finland, told AFP that with a very large sample and collaboration, and the ability to repeat the observation to be confident about the results, as well as recruitment of at least 10 000 patients, their project will hopefully help to develop a treatment.

"There are a huge number of medicines available that target specific genes. If we find a genetic clue that points us to a gene that already has a medication developed, then we could simply repurpose the drug," he said. However, in the event that mutations in genes are found and there arent currently medications available for them, it might make the process more complex.

On 12 May, the virus has infected more than 4.1 million people and killed over 286 000 worldwide, according to a report by theJohns Hopkins Coronavirus Resource Centre.

Viewpoint: Darwin’s ‘Descent of Man’ is both deeply disturbing and more relevant than ever – Genetic Literacy Project

Posted: May 16, 2020 at 11:48 am

Charles Darwins Descent of Man is full of unexpected delights such as the trio of hard drinking, chain-smoking koalas that appear within its first few pages to illustrate our affinity to animals.

Yet Darwins great treatise on human origins is also, in parts, deeply disturbing.

Published a century and a half ago as of February, 2021 many of the opinions expressed in this seminal text (koalas aside) are still pertinent today. Indeed, despite (or rather, because of) the recent revolution in our understanding of genetics, the Descent is more relevant than ever.

Darwins wider musings on mankind have had an immense and lasting influence on our beliefs about human nature and behavior, not just scientifically, but socially and politically as well. And while the more reprehensible later applications of evolutionary theory to human society were not truly Darwinian at all, many troubling arguments about race, class, eugenics and the like can nonetheless be discerned within his Descent of Man.

Darwins intellectual legacy is part of the DNA of modern genetics, within which still lurk like malignant metaphorical retroviruses liable to revival and resurgence many of the odious beliefs that plagued its past.

What follows, therefore, are a few brief illustrative examples of problematic passages in the Descent of Man. The point is not as is common with many of Darwins detractors to simply cherry-pick quotes to make Darwin look bad (although, unfortunately, this is easy to do); rather it is to highlight how Darwin himself struggled with the social implications of his theory and this despite the many decades he had to dwell on these questions. Indeed, the rapid, recent explosion in our knowledge of genetics has not made the situation clearer, but rather more confused.

But lets begin with the contrast of some of the more captivating aspects of the Descent those which provide a glimpse of Darwin as an actual human being. (The on-going fascination with Darwin and the impetus for the seemingly inexhaustible Darwin Industry is not just due to his ideas and his genius, but also because he was a fascinating individual.)

Within the first few pages of Chapter 1, for example, Darwin notes that [m]any kinds of monkeys have a strong taste for tea, coffee, and spirituous liquors: they will also, as I have seen, smoke tobacco with pleasure. Not content with this as a single amusing anecdote of animals addictive affinities to mankind, he proceeds to discuss the three koalas mentioned above ones that acquired a strong taste for rum, and for smoking tobacco and an American Ateles monkey that, after getting drunk on brandy, would never touch it again, and thus was wiser than many men. He also delights in describing the consequences for a group of African baboons of over-indulgence in strong beer:

On the following morning they were very cross and dismal; they held their aching heads with both hands, and wore a most pitiful expression: when beer or wine was offered them, they turned away with disgust

Similar endearing animal anecdotes pepper the rest of the text, culminating after chapter upon chapter of detailed argument and speculation on the evolutionary origins of mankind (plus an extended interlude of the theory of sexual selection) with the rousing conclusion that we should not feel much shame, if forced to acknowledge that the blood of some more humble creature flows in [our] veins.

For my own part I would as soon be descended from that heroic little monkey, who braved his dreaded enemy in order to save the life of his keeper; or from that old baboon, who, descending from the mountains, carried away in triumph his young comrade from a crowd of astonished dogsas from a savage who delights to torture his enemies, offers up bloody sacrifices, practices infanticide without remorse, treats his wives like slaves, knows no decency, and is haunted by the grossest superstitions.

Darwin clearly liked animals better than people. Less facetiously, it is lurid passages such as these that make modern readers uncomfortable. Admittedly, this particular quotation does come straight after another glimpse of Darwin as an actual person; already in his sixties when he wrote these words, he evokes the memories of his 20-something self, aboard the Beagle, on first seeing a party of Fuegians on a wild and broken shore:

The astonishment which I felt will never be forgotten by me for the reflection at once rushed into my mindsuch were our ancestors. These men were absolutely naked and bedaubed with paint, their long hair was tangled, their mouths frothed with excitement, and their expression was wild, startled, and distrustful.

Given a modern appreciation of the manifold horrors of colonialism, it is a thorny question how we should deal with descriptions that clearly reflect the prejudices of their author. Does such obvious subjective opinion, for example, undermine the purportedly objective arguments that accompany it?

In this instance at least we can perhaps make allowances; after all, the first encounter between Darwin a wealthy young man from what was then the most technologically-advanced nation in the world and the Stone Age inhabitants of Tierra del Fuego must indeed have been astonishing. Moreover, unlike his cousin Francis Galton (who both coined and promoted the concept of eugenics), Darwin was not an explicit racist. (His loathing of slavery, for instance, comes across particularly strongly in the Journal of the Voyage of the Beagle.) Yet Darwin was also a product of a time when it seemed patently obvious that the English (and possibly the Scots) were the first among the civilized races. Further, the Descent also reflects the prevailing concept of a human hierarchy, descending from Europeans through the various barbarous, savage or lower races to mankinds closest living relatives amongst the anthropomorphous apes.

In a now-notorious passage, Darwin ranks the native inhabitants of Africa and Australia as just above the gorilla in the natural scale. At the same time, he callously concludes that the civilised races of man will almost certainly exterminate, and replace, the savage races throughout the world.

Nor was Darwins chauvinism confined simply to other races the lower classes of his own society were equally a target for his blatant prejudice. Indeed, as he remarks, at least [w]ith savages, the weak in body or mind are soon eliminated; and those that survive commonly exhibit a vigorous state of health.

We civilised men, on the other hand, do our utmost to check the process of elimination; we build asylums for the imbecile, the maimed, and the sick; we institute poor-laws; and our medical men exert their utmost skill to save the life of every one to the last moment. Thus the weak members of civilised societies propagate their kind. No one who has attended to the breeding of domestic animals will doubt that this must be highly injurious to the race of man.

And it is perhaps here that Darwins legacy even if distorted and exaggerated by the likes of Galton is most worrying in the modern age of embryonic screening, genetic manipulation and, potentially, genetically-enhanced designer babies. Today we are increasingly able to use genetic techniques to eliminate deleterious genes such as those for Huntingtons disease from future generations. But where is the line between an obviously harmful trait and an undesirable one? Is termination of fetuses with Down syndrome actually eugenics? Or what about those screened as having autism?

In Darwins pre-genetic age, these were questions that could not yet be asked, let alone answered. Of more relevance, however, was Darwins personal concern, having married his first cousin, Emma Wedgewood, with the possible inherited ill-effects of inbreeding on his own children. But even here, as he confidently asserts in the Descent, science would eventually come up with an answer:

When the principles of breeding and inheritance are better understood, we shall not hear ignorant members of our legislature rejecting with scorn a plan for ascertaining whether or not consanguineous marriages are injurious to man.

Yet while science can certainly inform our moral (or, in this case, legal) decisions, it cannot decide them facts do not determine values. Darwin half-heartedly acknowledges this when he concedes we ought not check our sympathy [for the weak], even at the urging of hard reason, without deterioration in the noblest part of our nature.

In the concluding paragraph to the Descent of Man, he goes on to claim, we are not here concerned with hopes or fears, only with the truth as far as our reason allows us to discover it. And while many of Darwins own hopes and fears appear inextricably tangled with his subjective version of the truth, it is his final closing description of humankinds noble qualities and exalted powers that perhaps shows the way beyond these ethical dilemmas: the sympathy which feels for the most debased, the benevolence which extends not only to other men but to the humblest living creature, and our godlike intellect which has penetrated into the movements and constitution of the solar system.

Modern genetics now allows us to penetrate into the very constitution of life itself. Informed by the history of what Darwin and his followers got right and what they got wrong, surely we can extend our sympathy, our benevolence and our godlike intellect to confront the moral demons that this new exalted power has conjured in our path.

Introduction: DiGeorge syndrome critical region gene 8 (DGCR8) contributes to miRNA biogenesis, and defects in its expression could lead to defects in spermatogenesis.Methods: Here, we assess gene and protein expression levels of DGCR8 in the testicular biopsy specimens obtained from men with obstructive azoospermia (OA, n = 19) and various types of non-obstructive azoospermia (NOA) including maturation arrest (MA, n = 17), Sertoli cell-only syndrome (SCOS, n = 20) and hypospermatogenesis (HYPO, 18). Also, samples of men with NOA were divided into two groups based on successful and unsuccessful sperm recovery, NOA+ in 21 patients and NOA in 34 patients.Results: Examinations disclosed a severe decrease in DGCR8 in samples with MA and SCOS in comparison to OA samples (P < 0.001). Also, the results showed DGCR8 has significantly lower expression in testis tissues of NOA group in comparison to NOA+ group (p< 0.05). Western blot analysis confirmed that the DGCR8 protein was not expressed in SCOS samples and had a very low expression in MA and HYPO samples.Discussion: The results of this survey showed that DGCR8 is an important gene for the entire spermatogenesis pathway. Moreover, DGCR8 gene plays an important role in the diagnosis of NOA subgroups, and also the expression changes in it might contribute to SCOS or MA phenotypes. This gene with considering other related genes can also be a predictor of sperm retrieval.

California Stem Cell Research Institute Bond Initiative (2020)

Posted: May 16, 2020 at 11:47 am

The California Stem Cell Research Institute Bond Initiative (#19-0022) may appear on the ballot in California as an initiated state statute on November 3, 2020.

The ballot initiative would issue $5.5 billion in general obligation bonds for the California Institute for Regenerative Medicine (CIRM), which was created to fund stem cell research. The ballot initiative would require CIRM to spend no more than 7.5 percent of the bond funds on operation costs. The remaining bond funds would be spent on grants to entities that conduct research, trials, and programs related to stem cells, as well as start-up costs for facilities.[1]

The official ballot title is as follows:[2]

Authorizes Bonds to Continue Funding Stem Cell and Other Medical Research. Initiative Statute.[3]

The summary provided for inclusion on signature petition sheets is as follows:[2]

Authorizes $5.5 billion in state general obligation bonds to fund grants from the California Institute of Regenerative Medicine to educational, non-profit, and private entities for: (1) stem cell and other medical research, therapy development, and therapy delivery; (2) medical training; and (3) construction of research facilities. Dedicates $1.5 billion to fund research and therapy for Alzheimers, Parkinsons, stroke, epilepsy, and other brain and central nervous system diseases and conditions. Limits bond issuance to $540 million annually. Appropriates money from General Fund to repay bond debt, but postpones repayment for first five years.[3]

The fiscal impact statement is as follows:[2]

State costs of $7.8 billion to pay off principal ($5.5 billion) and interest ($2.3 billion) on the bonds. Associated average annual debt payments of about $310 million for 25 years. The costs could be higher or lower than these estimates depending on factors such as the interest rate and the period of time over which the bonds are repaid. The state General Fund would pay most of the costs, with a relatively small amount of interest repaid by bond proceeds.[3]

The full text of the ballot measure is available here.

Californians for Stem Cell Research, Treatments & Cures is leading the campaign in support of the ballot initiative.[4]

Ballotpedia has not identified individuals and entities opposing the ballot initiative. If you are aware of published opposition to the ballot initiative, you may send a reference link to editor@ballotpedia.org.

The Californians for Stem Cell Research, Treatments & Cures PAC was registered to support the ballot initiative. The committee had raised $6.06 million. Robert N. Klein II and Klein Financial Corporation provided $4.63 million to the PAC. The committee had expended $8.72 million (expenditures exceeded contributions due to accrued expenses).[6]

There were no PACs registered to oppose the ballot initiative.[6]

The following table includes contribution and expenditure totals for the committee in support of the ballot initiative.[6]

The following was the top donors to the support committee.[6]

In 2004, voters approved Proposition 71, which was a ballot initiative designed to establish a state constitutional right to conduct stem cell research, create the California Institute for Regenerative Medicine (CIRM), and issue $3.00 billion in general obligation bonds to fund CIRM.[7]

As of October 2019, CIRM had spent $2.91 billion of the $3.00 billion bond issue.[8]

In California, the number of signatures required for an initiated state statute is equal to 5 percent of the votes cast in the preceding gubernatorial election. Petitions are allowed to circulate for 180 days from the date the attorney general prepares the petition language. Signatures need to be certified at least 131 days before the general election. As the verification process can take multiple months, the secretary of state provides suggested deadlines for ballot initiatives.

The requirements to get initiated state statutes certified for the 2020 ballot:

Signatures are first filed with local election officials, who determine the total number of signatures submitted. If the total number is equal to at least 100 percent of the required signatures, then local election officials perform a random check of signatures submitted in their counties. If the random sample estimates that more than 110 percent of the required number of signatures are valid, the initiative is eligible for the ballot. If the random sample estimates that between 95 and 110 percent of the required number of signatures are valid, a full check of signatures is done to determine the total number of valid signatures. If less than 95 percent are estimated to be valid, the initiative does not make the ballot.

On October 10, 2019, Robert N. Klein filed the ballot initiative.[1] Attorney General Xavier Becerra (D) released ballot language for the initiative on December 17, 2019, which allowed proponents to begin collecting signatures. The deadline to file signatures is June 15, 2020.

On February 13, 2020, proponents announced that the number of collected signatures surpassed the 25-percent threshold (155,803 signatures) to require legislative hearings on the ballot initiative.[9] In 2014, Senate Bill 1253 was enacted into law, which required the legislature to assign ballot initiatives that meet the 25-percent threshold to committees to hold joint public hearings on the initiatives not later than 131 days before the election.

On March 21, 2020, Sarah Melbostad, a spokeswoman for Californians for Stem Cell Research, Treatments, and Cures, reported that the campaign's signature drive was suspended due to the coronavirus pandemic. Melbostad said, "In keeping with the governors statewide order for non-essential businesses to close and residents to remain at home, weve suspended all signature gathering for the time being. ... Were confident that we still have time to qualify and plan to proceed accordingly."[10]

On May 5, 2020, the campaign reported submitting about 925,000 signatures for the ballot initiative.[11] At least 623,212 of the signatures need to be valid. The recommended deadline to file signatures for the election on November 3, 2020, was April 21, 2020. Counties need to validate the signatures before June 25, 2020, for the ballot initiative to appear on the ballot in 2020. Otherwise, the ballot initiative would appear on the ballot on November 8, 2022.

BUSINESS: Can lab-grown meat save the planet and dinner? – E&E News

Posted: May 16, 2020 at 11:47 am

The idea is hard to stomach at first: animal meat grown in a lab.

But proponents of "cell-based meat" say the emerging technology has the potential to tackle two global problems at once. Lab-grown beef patties, chicken cutlets and even exotic proteins could help satisfy the world's growing appetite for meat, they argue. And it could be done in a way that cuts down on the tremendous environmental impact of animal agriculture.

Standing in the way is a long list of challenges including regulatory obstacles, sky-high production costs and the ever-present ick factor.

Still, advocates say lab-grown meat could hit store shelves as soon as 2025 if not earlier.

One proponent is Krijn de Nood, the chief executive of Meatable, a Netherlands-based company that is producing animal tissue by mimicking the cellular growth that typically happens inside rather than outside of living organisms. In an interview, de Nood said Meatable is "mission driven" and that it aims to address issues from climate change to animal welfare.

The company is among dozens of startups worldwide that are racing to scale technology they claim produces "real meat" not plant-based alternatives from companies such as Impossible Foods and Beyond Meat (Climatewire, Oct. 21, 2019).

That's possible, they say, because most cultured protein products originate as stem cells from real animals. Some companies make a point to say that no animals are harmed in the process.

Here's how it typically works. Engineers obtain an animal stem cell sample and isolate "cell lines" with the strongest genetic material. The cells are then placed in an environment like a petri dish or bioreactor that encourages rapid growth, and later differentiation. The resulting fat and muscle tissue is then harvested, structured and processed to create a final product.

De Nood said Meatable already has produced small quantities of meat using this process. And the whole thing took just three weeks a far faster timeline, Meatable notes, than it takes to raise an animal for slaughter. The company plans to host its first public taste testing of a pork prototype in September.

Several other companies already have allowed outsiders to sample their products. Those include Memphis Meats, Peace of Meat and Mosa Meat, which are based in the U.S., Belgium and the Netherlands, respectively.

In fact, one of the first cultured meat tastings dates back to 2013, when Maastricht University physiologist Mark Post presented the world with a beef patty that was produced in a petri dish.

At the time, that single slab of meat cost a whopping 250,000 to produce; Google co-founder Sergey Brin picked up the tab. Several years later, Post co-founded Mosa Meat.

More recently, in March, Peace of Meat hosted an event where attendees sampled a chicken nugget.

Tasting aside, co-founder David Brandes underscored that the startup has a different ambition than many other companies. Rather than producing consumer-facing products, Peace of Meat aims to eventually grow more than 100,000 tons of pure, cultured fat per year. The startup plans to sell the fat to other companies as a key ingredient to enhance the taste and texture of alternative meat products, including those that are plant-based.

"We don't want to make the most fancy-looking piece of food, we don't want to work on exotic species," said Brandes. "You need to produce massive amounts of meat if you really want to have an impact."

Animal agriculture is responsible for a whopping 14.5% of planet-warming emissions, according to the Food and Agriculture Organization of the United Nations. That figure includes greenhouse gases attributable to meat processing, meat-related transportation and manure storage. Then there's the issue of belching cattle which itself is responsible for 65% of the livestock sector's emissions.

Paul Mozdziak, who serves as Peace of Meat's chief scientific officer, was among those who said a central goal of cellular agriculture is to satisfy the world's staggering, and still rising, demand for animal protein but without relying on supply chains that scientists say are environmentally fraught and highly vulnerable to marketplace disruptions.

As an example, Mozdziak pointed to the novel coronavirus crisis, which in recent weeks has temporarily shuttered meat packing plants, forced farmers to cull tens of thousands of animals and spurred fears of a nationwide protein shortage (Greenwire, May 4).

"I absolutely think the pandemic supports the need for this," said Mozdziak, who also directs North Carolina State University's graduate physiology program.

"It's another way to produce food. It's another way to produce protein. It's another way to increase food security," he added. "What if something [else] happens? ... [W]here's the protein going to come from? How are we going to eat?"

But even Mozdziak, who has pondered cultured meat since the early 1990s, acknowledged the obstacles ahead. Despite entrepreneurs' ambitions, he said, the field remains deep in research and development and far from supermarket shelves.

De Nood, of Meatable, highlighted that same issue. "It's all about the scalability of the process," he said, noting that his company is working to drive down costs and move its operations from "small environments" to large bioreactors that would require major processing factories.

Peace of Meat's Brandes agreed. But he said that even if production costs fall, there's the possibility that cultured meat would not meaningfully impact the carbon footprint of the global food system.

"When it comes to greenhouse gas emissions, I think there is a big potential," said Brandes. But producing large quantities of cultured meat would inevitably require substantial amounts of energy, too, "so it really depends where you draw the energy from," Brandes said.

Despite those obstacles and more, some projections have named cultured meat as a key driver of a revolutionary shift away from animal agriculture. Independent think tank RethinkX, for instance, predicts that cell-based meat and plant-based alternatives could render industrial cow farming "obsolete" in the U.S. entirely.

Ermias Kebreab, who is a climate and animal agriculture expert at the University of California, Davis, disagreed with that assessment.

Even as the world becomes more invested in exploring alternatives to conventional protein, Kebreab said, researchers and traditional farmers are actively developing strategies like feeding seaweed to cows to cut the sector's environmental footprint.

In his eyes, sustainable agriculture, rather than cellular agriculture, is what will ultimately enhance food security in developing countries where most future population growth is predicted to occur.

"I'd rather have beef" from cows, said Kebreab, adding that cell-based meat also raises other issues for him, like the products' overall nutritional value. He said he's wary of "highly, highly processed food."

Mozdziak, of Peace of Meat, agreed in part. He doesn't see cellular agriculture putting meat companies out of business.

But "at the same time," he said, "let me vehemently state that I think cultured meat is really important. ... [I]f we're going to have a billion more people on the planet in 30 years, we're going to have to find a way to feed them."

Sharpless: COVID-19 threatens to reverse long-running trend of decreasing cancer mortality – The Cancer Letter

Posted: May 16, 2020 at 11:47 am

Today I would really like to keep most of the focus on regular NCI business. Im really eager, in fact, to be talking about cancer research and concepts the NCI would like to release. And these will spur interest in cancer research and priority areas. But there is a pandemic going on and we do have some coronavirus items to address as well.

We just had a board meeting on this topic almost entirely devoted to COVID-19. We dont have to do a whole lot on that topic today. But I will just use a few slides to summarize that presentation from the joint board meeting, and remind you of how the NCI has been taking a critical role in an unprecedented response to this pandemic. Also, since things are moving so fast around here right now, there actually have been a few significant developments in the coronavirus spacesince even the joint board meeting just a few weeks ago. Ill briefly summarize that news as well.

In particular, related to those developments, including a new and correct congressional appropriation. There are some COVID items that we do need, and Dinah Singer will direct that discussion at the end of todays meeting.

But let me start out our short COVID discussion by repeating a statement I made last month at the joint board meeting, which is that the primary focus of the National Cancer Institute is, and always will be cancer research and cancer care. Thats a message Ive been delivering in just about every presentation Ive given, in every email and blog post and other materials Ive written during this pandemic response.

And its one that Dinah Singer spoke to at her virtual presentation at AACR two weeks ago on April 28. If you havent seen this, I encourage you to check it out. Dinah also wrote a great post for our Bottom Line blog on the topic, which includes a link to the presentation.

So, this slide summarizes why the NCI is important to the pandemic response. It shows the disproportionate impact of COVID-19 on cancer patients, and patients with cancer whove survived cancer. Additionally, as I illustrated at the joint board meeting, the NCI has unique research expertise and capacity related to Frederick National Lab and our great extramural networks.

Therefore, we have to be involved in the pandemic response. And then, lastly, I think given the nature of this crisis, it has had a tremendous effect on public health. The NCI has a moral obligation to work in this area.

I want to call your attention though to the decrease in care delivery to cancer patients related to the coronavirus pandemic. And this is something, frankly, Ive been worrying about a lot lately, and Ive been hearing from a lot of you and other extramural leaders.

Ive been looking at the statistics about decreases in screening and deferred care, and I am getting very worried about this issue. The data regarding delayed diagnosis and delayed therapy are very clear from cancer research over the decades.

Delayed diagnosis and deferred care leads to worse outcomes for patients with cancer. The things we do to prevent cancer and to diagnose cancer and to treat cancer well, they work, and they cant be put off indefinitely.

And if we do, we will lose ground, and we will give up hard-won progress. And heres a very specific fear I have, in this regard. Every spring, the National Cancer Institute, with the CDC and the ACS and NAACCR, puts out our Annual Report to the Nation on our progress against cancer.

Thanks to advances in screening and prevention and treatment and survivorship, that document has become an annual feel-good story for the NCI. Every year Ive been here, the report has been good news.

Its been a couple of percent drops in cancer mortality each year, and thats been going on, in fact, for decades. But with all this deferred and delayed care and postponed surgeries and later, reduced chemotherapy, and canceled appointments for mammography or a Pap smear or colonoscopy, this is going to have an impact on cancer outcomesan impact that I think well see play out over years to come.

So, Im becoming worried that, because of the pandemic, that in 2021 or 2022 or 2023, we will have the first Annual Report to the Nation since 1993 that shows an increase in cancer mortality. And I know exactly what the statistics will mean for patients. I know that that represents more cancer suffering and more bad outcomes, and more deaths. And lets all agree, we dont want that to happen, and we wont let that happen. I know COVID has caused many changes to how we care for patients.

And we have a legitimate need to be careful during the pandemic in order to protect the public health. But we need to get back to work of caring for our patients. We need our hospitals and our clinics and our infusion centers to start doing what they do best, which is care for our patients who need this. Of course, we have to do this in a manner that is smart, that is careful, that protects patients and staff alike from the coronavirus.

But we need to get back to work. The cost of deferred cancer care will be significant. Neglecting cancer will produce a negative impact on the public health, and one that may trouble our patients for years to come. I plan on talking a lot more about this in the coming weeks. And I havent even spoken about the debilitating impact on cancer science, by having these labs closed and postponedtremendous impact as well.

Just to remind you something that Dinah spoke about, and that is on the blog post as well, is the number of NCI COVID-19 funding opportunities that are somewhat new and recently posted, and still open. This is summarized here. I wont spend a lot of time on them, other than to say were taking both administrative supplements and competitive revisions.

We also had a good discussion at the joint board meeting about allowing a change of scope of certain grants, and we have received a small number of requests to do that, and are working through that. But I think that we are still considering administrative supplements and competitive revisions, and we will be making funding decisions related to these very soon.

Now with the COVID part of the discussion behind us, at least for the next few hours, lets return to regular NCI business. Frankly, I am really excited, as I said, to be able to spend most of our time today on advancing cancer research and cancer science. Getting these concepts that the BSA will see today is really a lot of work getting these things together.

I think you will be impressed or youll be really shocked by how much the NCI has been able to get done during a period of complete telework. I think this is a testament to the really extreme efforts of the trained professionals in the NCI to get this work done, no matter what the situation.

As always, its good to mention where we are in the appropriations outlook. Theres really not a lot to report. At this stage right now, much of Congresss focus has been on supplemental funding related to the coronavirus pandemic, and the work on the 2021 budget has been a little a bit behind that.

But Congress has been busy and has already passed these supplemental fundings, and as is widely reported, is working on a fifth emergency appropriations bill. At the same time, appropriators are starting to take up their work on the regular FY21 appropriations bill, and I suspect well be hearing more about that soon. So, stay tuned.

Some really wonderful news during the joint board meeting last month, I was able to share some news about Dan Gallahan assuming the permanent role as director of NCIs Division of Cancer Biology. And today Im very pleased to share that Phil Castle will soon take the helm at NCIs Division of Cancer Prevention.

Those of you who know, Phil is replacing Barry Kramer in this role, but DCP has been led for over a year now by Debbie Winn, serving in an acting capacity. Debbie has done a spectacular job in this rolevery hard to be an acting in this roleand I want to thank her for taking this on for the benefit of the NCI. I would like a virtual round of applause for Debbie. Yay Debbie!

Phil is joining us from Albert Einstein College of Medicine in New York, where he served as professor in the Department of Epidemiology and Population Health. He was also the executive director and co-founder of the Global Coalition Against Cervical Cancer.

Phil is no stranger to the NCI. He was a senior tenured investigator and tenure-track investigator in the Division of Cancer Epidemiology and Genetics from 2003 to 2011. While at NCI, he was the lead investigator on several epidemiologic studies, including the Mississippi Delta project, the HPV Persistence and Progression Cohort, and the guidelines cohort and cancer at Kaiser Permanente, Northern California, and the Anal Cancer Screening Study.

Im thrilled Phil is joining the NCI in this key role, and Im really excited to have him join and provide vision for the DCP mission regarding cancer prevention, screening and early detection. So, welcome, Phil.

Id like to give a brief update on the Childhood Cancer Data Initiative. We are anxiously anticipating an upcoming working group report for the joint board meeting in June. As some of you know, Jaime Guidry Auvil kicked off the BSA working group on March 27 and provided an overview of its activities, as well as its relationship with ongoing NCI pediatric initiatives.

While we await the report, its important to note that we are using the FY20 CCDI funding to support foundational aspects of childhood cancer research and data related to those efforts, from which to build CCDI in years FY21 to FY30. So, we are working on this at a good speed with the already appropriated funds and are eagerly awaiting more advice from the working group on the shape of this initiative.

Ill just mention that the cell-based therapy and vector production efforts at Frederick National Lab are proceeding apace. As I mentioned though at the joint board meeting, we have actually had our first trial, using a CAR T-cells prepared at Frederick, open. The virus production facility will soon come online. And well evaluate potential viral production projects proposed by the extramural community.

So, we envision Frederick will have capacity to make viral vectors as needed for extramural searchers. This will include both developmental and clinical trial proposals.

Needless to say, Im thrilled with the progress and ramping up of this facility. In fact, this summer we will begin accepting applications. Weve dedicated space to produce viral projects, so those of you who will need help producing virus for, say, a CAR T trial or some other related efforts, stay tuned for the announcement about the acceptance of applications.

I think many on this board are aware of the interesting pattern of prostate cancer statistics over the last few years, regarding incidence and mortality, with changing recommendations related to PSA screening. The NCI has been following this area carefully. We had a very large internal NCI meeting, spanning the gamut from basic researchers to clinical trialists, to population health science researchers, to discuss where our prostate cancer research portfolio ought to be, in light of these changing statistics, and we decided a good way to go forward would be to have a lot of advice from the extramural community.

And for that reason, were working towards a workshop next spring to bring in extramural perspective to convene the best folks to try and understand where the NCI should be focusing its research mission related to prostate cancer now. Bill Dahut and others are leading this effort at the NCI.

I thought Id mentioned a few quick research updates that we found exciting. I always like to try and at least note some of the great science that NCI has done, either intramurally, or funded extramurally, and always try and bring up a few recent items.

This is work from the DeNardo lab at Washington University, published recently in Cancer Cell, related to dendritic cells in tumor immunotherapy. It proposes that the number of dendritic cells in a tumor may explain why immunotherapy works for some cancers, but not others, and work in miceboosting dendritic cell number triggered an immune response in pancreatic cancer, which has been traditionally difficult in terms of immunotherapy. So exciting research proposals to follow.

Work from the Richard Kitsis lab at Albert Einstein tries to better understand the relationship between daunorubicin and doxorubicin and cardiomyopathy, and developed an experimental drug to prevent this chemotherapy-induced heart toxicity. It does so without interfering with the chemotherapys therapeutic ability to kill cancer cells in mice. So, interesting work for a long-standing problem related to the use of these agents at extended doses for patients.

In some microbiome research from Marcel van den Brink at Memorial Sloan Kettering in people with blood, hematologic malignancies, the health of their gut microbiome appears to affect the risk of dying after receiving allogeneic stem cell transplant, according to this NCI-funded study, published in the New England Journal of Medicine that got tremendous attention in the press. An exciting development to help improve outcomes for patients who need allogeneic transplantation.

Finally, in addition to our grantee blog, Bottom Line, which is now widely read, and our research enterprise blog, which is Cancer Currents, I also also want to remind everyone about an important resource on our cancer.gov site. This site is specifically designed for researchers with questions. And it is updated frequently with new information as it becomes available.

To date, weve tracked over 20,000 visits to these blogs and other researcher-focused web content. I wanted to stress that we know all too well that the extramural community, as is the case in nearly every sector of the nation, things are really hurting out there.

And regardless of how the back-to-business plan does roll out at various institutions, it will really take some time to bounce back. We know, for instance, that universities and institutions have begun furloughing staff and laying off researchers. We know clinical trials accrual is down, especially for non-treatment trials.

All of this will slow the pace of research, but beyond that and equally important, the public health crisis represents a real hardship for our families, our communities, and patients with cancer. NCI has not lost sight of this. Well do all we can help to recover from these significant setbacks.

Precision medicine guides choice of better drug therapy in severe heart disease – Science Codex

Posted: May 16, 2020 at 11:45 am

BIRMINGHAM, Ala. - Is personalized medicine cost-effective? University of Alabama at Birmingham researcher Nita Limdi, Pharm.D., Ph.D., and colleagues across the United States have answered that question for one medical treatment.

Patients experiencing a heart attack -- known as a myocardial infarction or an acute coronary syndrome -- have sharply diminished blood flow in coronary arteries, with a high risk of heart failure or death. Coronary angioplasty, a procedure to open narrowed or blocked arteries in the heart, and percutaneous coronary intervention, known as PCI or stenting, can restore blood flow to minimize damage to the heart. These procedures reduce the risk of subsequent major adverse cardiovascular events, or MACE, which include heart attacks, strokes or death.

But then, a treatment decision has to be made.

After stenting, all patients are treated with two antiplatelet agents for up to one year. Which combination of antiplatelets is best? The answer comes through pharmacogenomics, says Limdi, a professor in the UAB Department of Neurology and associate director of UAB's Hugh Kaul Precision Medicine Institute.

Pharmacogenomics combines pharmacology, the study of drug action, with genetics, the study of gene function, to choose the best medication according to each patient's personal genetic makeup. This is also called precision medicine -- tailored medical treatment for each individual patient.

The most commonly used antiplatelet combination after PCI is aspirin and clopidogrel, which is trademarked as Plavix. Clopidogrel is converted to its active form by an enzyme called CYP2C19. However, patients respond to clopidogrel differently based on their genetic makeup.

More than 30 percent of people have loss-of-function variants in the CYP2C19 gene that decrease the effectiveness of clopidogrel. The FDA warns that these patients may not get the full benefit of clopidogrel, which would increase the risk of MACE. So the FDA advises doctors to consider a different treatment such as prasugrel or ticagrelor, trademarked as Effient and Brillinta, to replace clopidogrel.

While most patients undergoing PCI receive clopidogrel without receiving any CYP2C19 loss-of-function testing, academic institutions like UAB that offer precision medicine use pharmacogenomics to guide the selection of medication dosing.

In 2018, Limdi and other investigators across nine United States universities -- all members of the Implementing Genomics in Practice consortium, or IGNITE -- showed that patients with loss-of-function variants who were treated with clopidogrel had elevated risks. There was a twofold increase in MACE risk for PCI patients, and a threefold increase in MACE risk among patients with acute coronary syndrome who received PCI, as compared to patients prescribed with prasugrel or ticagrelor instead of clopidogrel. Prasugrel and ticagrelor are not influenced by the loss-of-function variant and can substitute for clopidogrel, but they are much more costly and bring a higher risk of bleeding.

The IGNITE group then leveraged this real-world data to conduct an economic analysis to determine the best drug treatment for these heart disease patients.

A study led by Limdi and colleagues, published in the Pharmacogenomics Journal, examines the cost-effectiveness of genotype-guided antiplatelet therapy for acute coronary syndrome patients with PCI. This cost-effectiveness study is the first to use real-world clinical data; many cost-effectiveness studies use clinical trial data, which tends to exclude the sicker patients normally seen in clinical practice.

The study compared three main strategies: 1) treating all patients with clopidogrel, 2) treating all patients with ticagrelor, or 3) genotyping all patients and using ticagrelor in those with loss-of-function variants.

"We showed that tailoring antiplatelet selection based on genotype is a cost-effective strategy," Limdi said. "Support is now growing to change the clinical guidelines, which currently do not recommend genotyping in all cases. Evidence like this is needed to advance the field of precision medicine."

Costs, QALYs and ICERs

In the analysis, Limdi and colleagues considered differences in event rates for heart attacks and stent thrombosis in patients receiving clopidogrel versus ticagrelor versus genotype-guided therapy, during the one-year period following stenting. They also included medical costs from those events that are borne by the payer, such as admissions, procedures, medications, clinical visits and genetic testing. The analysis considered variations in event rates and medication costs over time to ensure that the results held under different scenarios.

The study uses an economic measure -- the QALY, which stands for the quality-adjusted life year.

"First, we looked at which strategy provided the highest QALY," Limdi said. "The QALY is the gold standard for measuring benefit of an intervention -- in our case, genotype-guided treatment compared to treatment without genotyping. Universal ticagrelor and genotype-guided antiplatelet therapy had higher QALYs than universal clopidogrel -- so those are the best for the patient."

But health care resources are not infinite. So, Limdi and colleagues then evaluated whether those interventions that have higher QALYs were also reasonable from a cost perspective. This analysis considered the willingness to pay. What would a payor or a patient pay for the highest QALY?

"In our case, the payor would recognize that ticagrelor is more expensive than clopidogrel -- $360 per month vs. $10 per month -- and there is a $100 cost for each genetic test," Limdi said. "So, from the payor perspective, the more effective strategy (one with a higher QALY) -- if more expensive (higher cost) -- would have to lower the risks of bad outcomes like heart attacks and strokes for the gains in QALY that are at, or below, the willingness-to-pay threshold."

A calculation called incremental cost-effectiveness ratios, or ICERs, assesses the incremental cost of the benefit (improvement in QALY). In the United States, a treatment is considered cost-effective if its associated ICER is at or below the willingness-to-pay threshold of $100,000 per QALY.

"In our assessment, the two strategies with the highest QALY had very different ICERs," Limdi said. "The genotype-guided strategy was cost-effective at $42,365 per QALY. Universal ticagrelor was not; it had an ICER of $227,044 per QALY."

The researchers also looked at some secondary strategies for a real-world reason. A number of clinicians now prescribe ticagrelor or prasugrel for the first 30 days after PCI, which is considered a period of greater risk, and then switch their patients to the less expensive drug clopidogrel.

The secondary analysis allowed Limdi and colleagues to explore the cost-effectiveness of giving all patients ticagrelor for 30 days, and then switching them to clopidogrel, without genetic testing, versus switching the patients based on genotype. Both strategies were better -- in terms of QALYs -- than a universal switch to clopidogrel at 30 days. However, neither of the two appeared to be cost-effective. Because these secondary strategies used estimated parameters, "the findings should only be considered as hypothesis-generating," Limdi said.

Scientists race to find a cure or vaccine for the coronavirus. Here are the top drugs in development – CNBC

Health officials and scientists across the world are racing to develop vaccines and discover effective treatments against the coronavirus, which has infected more than 4.2 million people worldwide in as little as four months, according to data compiled by Johns Hopkins University.

There are no proven, knockout treatments and U.S. health officials say a vaccine could take at least a year to 18 months.

On May 1, theFood and Drug Administration granted emergency use authorizationfor Gilead Sciences' antiviral drug remdesivir. This after a government-run clinical trial found Covid-19 patients who took remdesivir usually recovered after 11 days. That is four days faster than those who didn't take the drug. The EUA means doctors in the U.S. will be allowed to use remdesivir on patients hospitalized with Covid-19 even though it has not been formally approved by the agency.

Even if the drug wins final approval, infectious disease specialists and scientists say researchers will need an arsenal of medications to fight this respiratory virus, which can also attack the cardiovascular, nervous, digestive and other major systems of the body.

Below is a list of the leading vaccines and drugs in development to battle Covid-19.

Moderna

The National Institutes of Health, an agency within the Department of Health and Human Services, has been fast-tracking work with biotech company Moderna to develop a vaccine to prevent Covid-19.The company began the first phase 1 human trialon45 volunteers testing a vaccine to prevent the disease in March and has been approved to soon start its phase 2, which would expand the testing to 600 people, by late May or June. If all goes well, its vaccine could be in production as early as July.

Moderna's potential vaccine contains genetic material called messenger RNA, or mRNA, that was produced in a lab. The mRNA is a genetic code that tells cells how to make a protein and was found in the outer coat of the new coronavirus, according to researchers at the Kaiser Permanente Washington Health Research Institute. The mRNA instructs the body's own cellular mechanisms for making proteins to create those that mimic the virus proteins, thereby producing an immune response.

Johnson & Johnson

Johnson & Johnson began Covid-19 vaccine development in January. J&J's lead vaccine candidate will enter a phase 1 human clinical study by September, the company announced in March, and clinical data on the trial is expected before the end of the year. If the vaccine works well, the company said it could produce600 million to 900 million doses by April 2021.

The company said it is using the same technologies it used to make its experimental Ebola vaccine, which was provided to people in the Democratic Republic of Congo in late 2019. It involves combing genetic material from the coronavirus with a modified adenovirus that is known to cause common colds in humans.

Inovio Pharmaceutical

Inovio began its early stage clinical trials for a potential vaccine on April 6,making it the second potential Covid-19 vaccine to undergo human testing after Moderna. It says it will enroll up to 40 healthy adult volunteers in Pennsylvaniaand Missouri and expects initial immune responses and safety data by late summer. Inovio made its potential vaccine by adding genetic material of the virus inside synthetic DNA, which researchers hope will cause the immune system to make antibodies against it.

Oxford University

A coronavirus vaccine developed by researchers at Oxford University began phase 1 human trials on April 23. British Health Minister Matt Hancock saidthat he wouldprovide 20 million, ($24.5 million), to help fund the Oxford project. The team said it aims to produce 1 million doses by September.

Oxford researchers are calling their experimental vaccineChAdOx1 nCoV-19, and it's a kind ofrecombinant viral vector vaccine. Like J&J's team, the researchers will place genetic material from the coronavirus into another virus that's been modified. They will then inject the virus into a human, hoping to produce an immune response.

Pfizer

Pharmaceutical giant Pfizer,which is working alongside German drugmaker BioNTech, began testing an experimental vaccine to combat the coronavirus in the U.S. on May 5.The U.S.-based drugmaker hopes to produce "millions" of vaccines by the end of this year and expects to increase to "hundreds of millions" of doses next year. The experimental vaccine uses mRNA technology, similar to Moderna. The mRNA is a genetic code that tells cells what to build in this case, an antigen that may induce an immune response for the virus.

Sanofi and GSK

Sanofi and GSKannouncedApril14 that they had entered an agreement to jointly create a Covid-19 vaccineby the end of next year.The companies plan to start clinical trials in the second half of 2020 and, if successful, produce up to 600 million doses next year. To make it, Sanofi said it will repurpose its SARS vaccine candidate that never made it to market while GSK will provide pandemic adjuvant technology, which is meant to enhance the immune response in vaccines.

Novavax

Novavax announced on April 8 it found a coronavirus vaccine candidate and would start human trials in May with preliminary results expected in July. The potential vaccine, which is being calledNVX-CoV2373, is usingadjuvant technology and will attempt to neutralize the so-called spike protein, found on the surface of the coronavirus, which is used to enter the host cell.

Gilead Sciences

The FDA granted emergency use authorization for Gilead's remdesivir drug to treat Covid-19 on May 1. The National Institute of Allergy and Infectious Diseases released results from its study showing patients who took remdesivir usually recovered faster than those who didn't take the drug. Even though remdesivir was granted for emergency use, there are still several ongoing clinical trials testing whether it's effective in stopping the coronavirus from replicating.

Remdesivir has shown some promise in treating SARS and MERS, which are also caused by coronaviruses. Some health authorities in the U.S., China and other parts of the world have been using remdesivir, which was tested as a possible treatment for the Ebola outbreak, in hopes that the drug can improve the outcomes for Covid-19 patients. The company said it expects to produce more than 140,000 rounds of its 10-day treatment regimen by the end of May and anticipates it can make 1 million rounds by the end of this year.

New York state and others

Hydroxychloroquine is a decades-old malaria drug touted by PresidentDonald Trumpas a potential "game-changer."

The drug is proven to work in treating Lupus and rheumatoid arthritis, but not Covid-19. A handful of small studies on its use in coronavirus patients published in France and China had raised hope that the drug might help fight the virus. However, hydroxychloroquine, which is available as a generic drug and is also produced under the brand name Plaquenil by French drugmaker Sanofi, can have serious side effects, including muscle weakness and heart arrhythmia.

The FDA issueda warning against takingthe drug outside a hospital or formal clinical trial setting after it became aware of reports of "serious heart rhythm problems" in patients.

On March 24, researchers at NYU Langone in New York launchedone of the nation's largest hydroxychloroquine clinical studiesafter federal health regulators fast-tracked approvals for coronavirus research, allowing scientists across the nation to skip through months of red tape. It's one of more than a dozen formal studies in the U.S. looking at treatments for the coronavirus,according to ClinicalTrials.gov.

But the early results aren't so promising. An observational study published in thejournal JAMA Network Open on Monday and run by the New York State Department of Health, in partnership with the University of Albany, found that it didn't help coronavirus patients. Worse yet, when taken with azithromycin which French researchers credited with speeding recovery times it put patients at significantly higher risk of cardiac arrest.

Zhejiang Hisun Pharmaceutical

Favipiravir is an anti-flu drug sold byFujifilm Holding under the name Avigan. Researchers in China are testing the drug to see if it's effective in fighting the coronavirus. Most of favipiravir's preclinical data is derived from its influenza and Ebolaactivity; however, the agent also demonstrated broad activity against other RNA viruses, according to researchers in Japan.

Regeneron and Sanofi

Regeneron and Sanofi started clinical trials of rheumatoid arthritis drug Kevzara in Covid-19 patients in March.The drug inhibits a pathway thought to contribute to the lung inflammation in patients with the most severe forms of Covid-19.

The companies announced last month that Kevzara showed promise for treating the sickest coronavirus patients in a clinical trial but it wasn't beneficial for patients with less-advanced disease, prompting the companies to stop testing the medicine in that group.

Eli Lilly

Eli Lilly, in partnership with National Institute of Allergy and Infectious Diseases, is seeing if its rheumatoid arthritis drugbaricitinib is effective against the coronavirus.The company theorizes that baricitinib's anti-inflammatory effects could curb the body's reaction to the virus.

Eli Lilly, AstraZeneca and Regeneron

While some drugmakers are looking for vaccines to stop the virus, Eli Lilly, AstraZeneca and Regeneron, among other companies, are working on so-called antibody treatments, which are made to act like immune cells and may provide protection after exposure to the virus. Earlier this month,Regeneron said its treatment could be available for use by the end of this summer or fall.
