DNA-editing method shows promise to treat mouse model of progeria – National Institutes of Health

Posted: January 8, 2021 at 3:50 pm

News Release

Wednesday, January 6, 2021

Using a recently developed DNA base-editing technique, researchers correct accelerating aging disorder.

Researchers have successfully used a DNA-editing technique to extend the lifespan of micewith thegenetic variationassociated withprogeria, a rare genetic disease that causes extreme premature aging in children and can significantly shorten their life expectancy. The studywas published in the journalNature, and was a collaboration between the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health; Broad Institute of Harvard and MIT, Boston; and the Vanderbilt University Medical Center, Nashville, Tennessee.

DNA is made up of four chemical bases A, C, G and T. Progeria, which is also known as Hutchinson-Gilford progeria syndrome, is caused by a mutation in the nuclear laminA(LMNA) gene in which one DNA base C is changed to a T. This change increases the production of the toxic protein progerin, which causes the rapid aging process.

Approximately 1 in 4 million children are diagnosed with progeria within the first two years of birth, and virtually all of these children develop health issues in childhood and adolescence that are normally associated with old age, including cardiovascular disease (heart attacks and strokes), hair loss, skeletal problems, subcutaneous fat loss and hardened skin.

For this study, researchers used a breakthrough DNA-editing technique calledbase editing, which substitutes a single DNA letter for another without damaging the DNA, to study how changing this mutation might affect progeria-like symptoms in mice.

"The toll of this devastating illness on affected children and their families cannot be overstated," said Francis S. Collins, M.D., Ph.D., a senior investigator in NHGRI's Medical Genomics and Metabolic Genetics Branch, NIH director and a corresponding author on the paper. "The fact that a single specific mutation causes the disease in nearly all affected children made us realize that we might have tools to fix the root cause. These tools could only be developed thanks to long-term investments in basic genomics research.

The study follows another recent milestone for progeria research, as theU.S. Food and Drug Administration approved the first treatment for progeriain November 2020, a drug called lonafarnib. The drug therapy provides some life extension, but it is not a cure. The DNA-editing method may provide an additional and even more dramatic treatment option in the future.

David Liu, Ph.D., and his lab at the Broad Institute developed the base-editing method in 2016, funded in part by NHGRI.

"CRISPR editing, while revolutionary, cannot yet make precise DNA changes in many kinds of cells," said Dr. Liu, a senior author on the paper. "The base-editing technique we've developed is like a find-and-replace function in a word processor. It is extremely efficient in converting one base pair to another, which we believed would be powerful in treating a disease like progeria.

To test the effectiveness of their base-editing method, the team initially collaborated with the Progeria Research Foundation to obtain connective tissue cells from progeria patients. The team used the base editor on theLMNAgene within the patients cells in a laboratory setting. The treatment fixed the mutation in 90% of the cells.

The Progeria Research Foundation was thrilled to collaborate on this seminal study with Dr. Collinss group at the NIH and Dr. Lius group at Broad Institute, said Leslie Gordon, M.D., Ph.D., a co-author andmedical director of The Progeria Research Foundation, which partially funded the study. These study results present an exciting new pathway for investigation into new treatments and the cure for children with progeria.

Following this success, the researchers tested the gene-editing technique by delivering a single intravenous injection of the DNA-editing mix into nearly a dozen mice with the progeria-causing mutation soon after birth. The gene editor successfully restored the normal DNA sequence of theLMNAgene in a significant percentage of cells in various organs, including the heart and aorta.

Many of the mice cell types still maintained the corrected DNA sequence six months after the treatment. In the aorta, the results were even better than expected, as the edited cells seemed to have replaced those that carried the progeria mutation and dropped out from early deterioration. Most dramatically, the treated mice's lifespan increased from seven months to almost 1.5 years. The average normal lifespan of the mice used in the study is two years.

As a physician-scientist, its incredibly exciting to think that an idea youve been working on in the laboratory might actually have therapeutic benefit, said Jonathan D. Brown, M.D., assistant professor of medicine in the Division of Cardiovascular Medicine at Vanderbilt University Medical Center. Ultimately our goal will be to try to develop this for humans, but there are additional key questions that we need to first address in these model systems.

Funding for the study was supported in part by NHGRI, the NIH Common Fund, the National Institute of Allergy and Infectious Diseases, the National Institute of Biomedical Imaging and Engineering, the National Institute of General Medical Sciences, the National Heart, Lung and Blood Institute and the National Center for Advancing Translational Sciences.

The Medical Minute: How the body responds to the COVID-19 vaccine – Penn State News

Posted: January 8, 2021 at 3:50 pm

By now, everyone has seen countless images of people receiving the COVID-19 vaccine. But once its injected into the upper arm, how does it actually interact with the body?

Dr. M. Fahad Khalid, chief of the Division of Hospital Medicine at Penn State Health Milton S. Hershey Medical Center, and Dr. Mohammad Ali, an infectious diseases physician at Penn State Health Holy Spirit Medical Center, say while the vaccine doesnt contain any live COVID-19 virus, it teaches the human immune system to protect against it.

Both vaccines that received Emergency Use Authorization from the U.S. Food and Drug Administration (FDA) the Pfizer-BioNTech and Moderna vaccines are mRNA (messenger RNA) vaccines. They are not live viruses. Instead, they work by giving your body a blueprint to create a piece of the virus that causes COVID-19, called a spike protein.

Once you receive the vaccine, your cells machinery uses the mRNA instructions to make the spike protein. This protein is then displayed on the cell surface, and the immune system sees it and responds to it. While mRNA is a type of genetic code, it never enters the center (nucleus) of your cells. That means it never converts into DNA, Khalid said. The mRNA itself is destroyed by the cells after they produce the spike protein.

The spike protein the vaccines create is the same one found on the surface of the virus that causes COVID-19. However, the vaccines do not contain any live virus. The spike protein itself cannot cause an infection, Ali said.

Khalid and Ali also addressed many common questions people have about both vaccines:

The vaccines were approved quickly. Are they safe? Advances in vaccinology and vaccine production allowed pharmaceutical companies to create vaccines in months. However, both vaccines followed rigorous FDA guidelines, including the normal regimen of clinical trials and Phase 1, 2 and 3 trials. Their effectiveness is tremendous, Ali said. The flu vaccine is typically 40% to 60% effective, and the COVID-19 vaccines are 94% to 95% effective.

Do people get severe allergic reactions to the vaccine? The Centers for Disease Control and Prevention (CDC) reports a limited number of incidents where people experienced a severe allergic reaction (anaphylaxis) or reaction such as hives, swelling or wheezing. The CDC recommends against people taking the vaccine who had a prior severe allergic reaction to any ingredient in the COVID-19 vaccine. People who have had allergic reactions to other vaccines should ask their doctor about taking the COVID-19 vaccine. People with nonvaccine-related allergies food allergies, pet allergies, seasonal allergies are safe to get vaccinated, says the CDC.

Will the vaccine side effects be worse than getting COVID-19? Possible side effects, such as swelling or pain at the injection site, fever, headache or muscle pain, are temporary. Those side effects arent nearly as bad as severe cases of COVID-19, which can be fatal, Khalid said.

Do I need a vaccine if I already had COVID-19? Yes. Currently, the CDC recommends vaccination even in people who have had COVID-19 in the past. This is because we do not know how long immunity to the virus lasts after someone is infected.

Do I need to wear a mask after getting the COVID-19 vaccine? Yes, you must continue to wear a mask, practice social distancing and continue to wash your hands. The vaccine protects you from getting sick with COVID-19, but researchers still dont know if individuals can still get infected and transmit the virus to others.

Is there any kind of microchip tracking in the vaccines? No. The vaccine also will not cause infertility. Theres a lot of misinformation out there, Ali said. The most trustworthy resource for accurate information is the CDC website.

Alison Enimpah, a registered nurse who provided direct care for COVID-19 patients at the Milton S. Hershey Medical Center, was among the earliest group of health care workers to get vaccinated. Shell receive her second dose later this month. The vaccine adds a layer of reassurance that were making forward progress in keeping ourselves and our community safe during the pandemic, she said.

Based on genes, nearly everyone is likely to have an atypical response to at least one drug – Scope

Posted: January 8, 2021 at 3:50 pm

Every drug, from morphine to ibuprofen, has a standard dose -- a sort of one-size-fits all recommendation. But a new study suggests that when it comes to drug doses, "one size fits all" rarely applies.

Stanford Medicine professor Russ Altman, MD, PhD, and a team of scientists found that almost everyone (99.5% of individuals) is likely to have an abnormal or "atypical" response to at least one therapeutic drug. This, at least, is the case for people in the United Kingdom, as the study's data came from the UK Biobank, a project that collects, studies and shares data.

The research found that nearly a quarter of the study's participants had been prescribed a drug for which they were predicted to have an atypical response, based on their genetic makeup. On average, participants were predicted to have an atypical response to 10 drugs.

"Ultimately, the hope is that we can show how pervasive drug response variability is and encourage more doctors to rethink the standard prescription protocols that are largely used today and use genetic testing to predict and adjust forthis variability," said Altman, who is an expert in pharmacogenetics, a field that studies the intersection of drugs and genetics.

An "atypical" drug response encompasses a lot of things; but generally speaking, it means a certain drug might not affect one person the way it does another.

For instance, someone who has an atypical metabolic response might process that drug more efficiently, strengthening its initial effects but decreasing its efficacy over time. On the flip side, it could mean that that person is unable to metabolize the drug at all, leaving them without therapeutic aid, or even with dangerous side effects.

These differences in response to a drug are partially due to our genetics. Specific proteins -- workhorse molecules in the body -- break down drugs in order for the body to benefit from the therapeutic. Those proteins are regulated by a specific group of genes. Natural variation in those genes leads to differences in how an individual's body reacts to a given drug molecule.

Altman and his team, including graduate students and first authors of the study Greg McInnes and Adam Lavertu, analyzed data from nearly 500,000 participants.

For 230,000 participants in the study, the team had primary care data going back about 30 years. That includes which drugs had been prescribed, the dose, and all of the patient's different diagnoses. The researchers also had access to detailed genetic information about each patient. They paid special attention to genetic variations in a group of genes that are known to influence the human drug response.

By comparing an individual's genetics against the variations known to exist in the group of drug-response-associated genes, the researchers could predict how any given patient might respond to a drug.

"Pharmacogenetics as a field has been around for a long time, but it hasn't really been adopted into clinical use," McInnes told me. "It's been growing in the last few years as more people realize the impact that it could have on personalized health. For a long time, it's been this overlooked aspect of genetics that I think is actually one of the most clinically actionable advances that has come out of human genetics."

What's more, he said, the wide variability in the human drug response applies to common therapeutics most everyone has encountered or is familiar with -- ibuprofen, codeine, statins and beta blockers among others.

Moving forward, Lavertu says that the goal is to expand drug-gene variant interaction analyses into more diverse populations. The data from the UK Biobank provided critical insight, but it was largely only representative of a British population, where the majority shares European ancestry. A next step for the researchers is to investigate the same genes in the Million Veteran Program, a government research program with a more diverse study population, that is examining how genes, lifestyle and military exposures affect health and illness.

"Our hope is that doing more of these studies will help us find new relationships between genetic variants and drug response, so that pharmacogenetics can benefit more people," Lavertu said.

Developmental Biologist Kathryn Anderson Dies at 68 – The Scientist

Posted: January 8, 2021 at 3:50 pm

Kathryn Anderson, a developmental biologist at the Memorial Sloan Kettering Cancer Center known for her work detailing the genetics of early embryogenesis, died November 30 at age 68.

Throughout her scientific career, Anderson used rigorous genetic screening assays to identify mutations suspected of disrupting cell division and differentiation in model systems. Having identified a gene of interest, she would then turn to a technique known as forward genetics, creating model organisms such as fruit flies and mice with a particular phenotype to better understand its molecular underpinnings. Using these tools, Anderson made important contributions to scientists understanding of several genetic pathwaysmost notably the Toll and Hedgehog pathwaysrequired for proper development of these animals.

Kathryn was fearless and very open-minded, Tatiana Omelchenko, a senior research scientist in Andersons lab who uses confocal microscopy to do live imaging of mouse embryos, tells The Scientist. Every lab has its own environment and its own mood, and when you stepped into Kathryns lab, you immediately felt very focused.

Born in La Jolla, California, in 1952, Anderson became interested in science at a young age, stemming back to an article in LIFEthat included a detailed image of a human fetus, according to an interview released shortly after her death. She attended the University of California, Berkeley, where she earned her undergraduate degree in biochemistry before heading to a graduate program in neurodevelopment at Stanford University in 1973.

Anderson left that program after only two years, earning a masters degree in neuroscience, and spent the next several years looking for her scientific niche. She enrolled briefly in medical school at the University of California, San Diego, an experience that led her to realize her love of basic research. The clinical work wasnt my cup of tea, Anderson shared in a 2005 biography. The lab was where I felt most at home.

Ultimately, Anderson landed at the University of California, Los Angeles, studying the developmental genetics of Drosophilaunder the guidance of biologist Judith Lengyel. For her PhD work, Anderson showed that in the first two hours after fertilization, the development of Drosophilaembryos remains under maternal control, with maternal RNA and proteins directing cell division and differentiation within the egg.

Looking to further her study of fruit flies, Anderson next traveled to the Max Planck Institute for Developmental Biology in Germany as a postdoc to work with Drosophilageneticist Christiane Nsslein-Volhard. In 1995, Nsslein-Volhard would share a Nobel Prize for her work using mass screenings to identify mutations that disrupt embryonic development, and Anderson would continue studying a handful of the genes identified in these early screens throughout her career.

One such gene, known as Toll, turned out to play an important role in dorsal-ventral (D-V) differentiationdictating, as Anderson said in her biography, how a fly embryo knows its back from its belly. In addition to probing the function of Toll,Anderson continued building out the wider Toll pathway after returning to the University of California, Berkeley, as an assistant professor in 1985, and later in her own lab at the Sloan Kettering Institute, which she launched in 1996 at Memorial Sloan Kettering. During this time, Anderson and her team identified roughly a dozen genes involved in cell differentiation along the D-V axis, and she used similar screening methods to better understand Tolls role in innate immunity of Drosophila. Her findings were noted by geneticists Jules Hoffmann and Bruce Beutler, whose study of Toll-like receptors in both fruit fly and mammalian immunity would later earn them a Nobel Prize.

After her successes in fruit flies, Anderson began thinking about applying her same methods to the study of mice. She spent a year on sabbatical in the lab of Rosa Beddington at the National Institute for Medical Research in the UK, where she showed that Toll had no analogous role in the D-V differentiation of mammals. It demonstrated, she said in a 2016 interview with Development, that there are things about early mammalian development that you cant figure out by extrapolating from flies.

Back at the Sloan Kettering Institute, Anderson began once again using mass genetic screenings, this time to identify mutations of interest in mice, and then studying them in fine detail. These were lengthy experiments that often took years to yield results. I think her major contribution is discovering the functions and roles of genes through this mutagenesis screen, Omelchenko says. This is amazing because . . . the mouse embryo model is quite complex, but she did the work.

Anderson and her team screened more than 12,000 mutations, selecting roughly 40 that produce obvious phenotypic disruptions midway through gestation. Working diligently over many years, Anderson identified previously unknown pathways that have since prompted new research directions in the field of developmental biology.

Through her screening, for example, Anderson identified a previously unknown relationship between ciliamicroscopic, hairlike structures on the outside of some cellsand proper signaling of the Hedgehog pathway that dictates cell differentiation in mammalian embryos. Further research showed that components of this pathway are enriched in cilia, while mice with certain mutations in genes involved in Hedgehog signaling lacked cilia altogether in a structure called the node that directs gastrulation in vertebrate embryos. That turned out to be pretty amazing, actually: theres this whole organelle required for Hedgehog signaling in vertebrates, but not in flies, Anderson said in her Developmentinterview. Its a geneticists dream, but raises the question of why organize the genome like this: there are so many weak points in Hedgehog signalingand Hedgehog is so vital.

For her contributions to the field of developmental biology, Anderson was inducted into the National Academy of Sciences in 2002 and elected as a member of the Institute of Medicine of the National Academies in 2008. In addition, she was awarded the Thomas Hunt Morgan Medal for lifetime contributions to the science of genetics in 2012, the Federation of American Societies for Experimental Biologys Excellence in Science Award in 2014, and the Society for Developmental Biologys Edwin G. Conklin Medal for distinguished and sustained research in 2016, among other honors.

Prior to her death, Anderson had spoken about the possible extension of her research into human genetics, as disruptions in hedgehog signaling have since been linked both to birth defects and to a series of diseases referred to as ciliopathies. It was, however, a line of questioning she planned to leave to other scientists, content to continue her methodical work exploring mutations in mice.

Many scientists are very quiet people, but contemporary society requires you to be very loud [so] that people will listen to you, Omelchenko says. Kathryn is such a great example of being quiet, being a very deep thinker, and at the same time becoming a very successful and bright scientist. I think I will keep learning from her even though she has passed away.

Anderson is survived by her husband, Timothy Bestor, a geneticist at Columbia University.

The risk related to genetic data is anticipated to limit the growth of the biotechnology services market. The biotechnological approach of transferring specially created genes for modification in characteristics to create genetically modified organisms (GMOs) has always been considered a threat to human and environmental health. According to the report of the World Conservation Union, there are numerous environmental risks likely to occur by the use of GMOs, which include interbreeding, antibiotic resistance, impact on the ecosystem, creation of new or worse viruses, competition with natural species, unpredictable and unintended effects and ethical concerns.

Collaborations and partnerships between industry players are a growing trend in the field of biotech services. In Dec 2019, Interpace Pharma, a subsidiary of Interpace Biosciences, dealing in pharmacogenomics testing, genotyping and biorepository services, collaborated with Genecast Biotechnology Co. Ltd for jointly developing, promoting, and offering translational studies and clinical trial solutions to the industry. This partnership is expected to benefit pharmaceutical and biotech companies to accelerate their biomarker-driven drug development and precision medicine.

The increasing pervasiveness of conditions like hepatitis B, diabetes and cancer is driving the research in biotechnology. Biotechnology uses research tools from biology and chemistry to study the genetic material of bacteria and viruses to check the disease-producing agent. Oncology research is most prominent among biopharma companies. Stem cell treatment, using a monoclonal antibody for therapy and genome sequencing is progressing in medical applications. The sales of global biotech drugs are expected to reach $284 billion in 2020.

According to Data-Driven Investor, all sectors of biotech companies together spend 20% of their budget on research and development, accounting for nearly $750 billion in 2018. Therefore, the rising pervasiveness of diseases and huge expenses on R&D is predicted to contribute to the growth of the biotechnology services market.

Alnylam Reports Positive Topline Results from HELIOS-A Phase 3 Study of Vutrisiran in Patients with hATTR Amyloidosis with Polyneuropathy – Business…

Posted: January 8, 2021 at 3:50 pm

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), the leading RNAi therapeutics company, announced today that the HELIOS-A Phase 3 study of vutrisiran, an investigational RNAi therapeutic in development for the treatment of transthyretin-mediated (ATTR) amyloidosis, met its primary and both secondary endpoints at nine months in patients with hATTR amyloidosis with polyneuropathy. The primary endpoint was the change from baseline in the modified Neuropathy Impairment Score (mNIS+7) at 9 months as compared to historical placebo data from the APOLLO Phase 3 study of patisiran. The two secondary endpoints were changes in quality of life assessed by the Norfolk Quality of Life Questionnaire-Diabetic Neuropathy (Norfolk QoL-DN) and gait speed assessed by the timed 10-meter walk test (10-MWT) compared to historical placebo. Vutrisiran met the primary endpoint (p less than 0.001) and achieved statistically significant results (p less than 0.001) for each of the Norfolk QoL-DN and 10-MWT secondary endpoints. In addition, vutrisiran treatment showed improvement compared to placebo on the exploratory cardiac biomarker endpoint, NT-proBNP (nominal p less than 0.05). Vutrisiran also demonstrated an encouraging safety and tolerability profile.

Based on these positive results, the Company plans to submit a New Drug Application (NDA) for vutrisiran with the U.S. Food and Drug Administration (FDA) in early 2021, and to follow with regulatory filings in additional countries, such as Brazil and Japan. The Company plans to submit a Marketing Authorisation Application (MAA) in the EU upon obtaining the results of the 18-month analysis expected in late 2021 as previously aligned with the European Medicines Agency (EMA).

We are excited to report positive topline results from the HELIOS-A study, which show that vutrisiran reduces neurologic impairment and improves quality of life in patients with hATTR amyloidosis with polyneuropathy as soon as 9 months, with an encouraging safety and tolerability profile. In addition, were very pleased to see evidence for reversal of polyneuropathy manifestations of disease and also favorable effects on the exploratory cardiac endpoint, NT-proBNP. We believe that vutrisiran, as a low-dose, once-quarterly, subcutaneously administered therapy, has the potential to be a highly attractive therapeutic option for patients living with this progressive, life-threatening, multi-system disease. We look forward to presenting the full 9-month results from HELIOS-A at a medical meeting in early 2021 and to announcing additional 18-month results, including additional exploratory cardiac endpoint data, in late 2021, said Akshay Vaishnaw, M.D., Ph.D., President of R&D at Alnylam. We would like to recognize and extend our profound gratitude to the patients, caregivers, investigators, and study staff who are participating in HELIOS-A and who, through their commitment during an especially difficult year, have helped make possible another potential advancement in the treatment of hATTR amyloidosis with polyneuropathy. We look forward to initiating our regulatory filings in early 2021 as we work to bring this investigational treatment one step closer to patients with this rare disease.

HELIOS-A (NCT03759379) is a Phase 3 global, randomized, open-label study to evaluate the efficacy and safety of vutrisiran. The study enrolled 164 patients with hATTR amyloidosis with polyneuropathy at 57 sites in 22 countries. Patients were randomized 3:1 to receive either 25mg of vutrisiran (N=122) via subcutaneous injection once every three months or 0.3 mg/kg of patisiran (N=42) via intravenous infusion once every three weeks (as a reference comparator) for 18 months. The primary endpoint is the change from baseline in mNIS+7 score at 9 months1, relative to historical placebo. Secondary endpoints at 9 months are the change from baseline in the Norfolk QoL-DN score and the timed 10-MWT, relative to historical placebo. Changes from baseline in NT-proBNP were evaluated as an exploratory endpoint at 9 months. The efficacy results of vutrisiran in HELIOS-A are compared to historical placebo control data from the landmark APOLLO Phase 3 study, which evaluated the efficacy and safety of patisiran in a patient population similar to that studied in HELIOS-A. Additional secondary endpoints at 18 months will be evaluated in the HELIOS-A study, including change from baseline in mNIS+7, Norfolk QoL-DN, 10-MWT, modified body mass index (mBMI), Rasch-built Overall Disability Scale (R-ODS), and serum transthyretin (TTR) levels. Additional exploratory cardiac endpoint data at the 18-month time point will be evaluated, including NT-proBNP, echocardiographic measures and cardiac amyloid assessments with technetium scintigraphy imaging. Following the 18-month study period, all patients are eligible to receive vutrisiran for an additional 18 months as part of an open-label extension study. Full 9-month results will be presented at a medical conference in early 2021 and topline 18-month results, including further exploratory cardiac endpoint data, are expected to be announced in late 2021.

Vutrisiran demonstrated an encouraging safety profile. There were two study discontinuations (1.6 percent) due to adverse events in the vutrisiran arm by Month 9, both due to deaths, neither of which was considered related to study drug. There were two serious adverse events (SAEs) deemed related to vutrisiran by the study investigator, consisting of dyslipidemia and urinary tract infection. Treatment emergent adverse events (AEs) occurring in 10 percent or more patients included diarrhea, pain in extremity, fall and urinary tract infections, with each of these events occurring at a similar or lower rate as compared with historical placebo. Injection site reactions (ISRs) were reported in five patients (4.1 percent) and were all mild and transient. There were no clinically significant changes in liver function tests (LFTs).

The HELIOS-A results reinforce our commitment to building an industry-leading franchise of medicines for the treatment of ATTR amyloidosis which began with the development and approval of ONPATTRO as a treatment for patients with hATTR amyloidosis with polyneuropathy. Indeed, the vutrisiran results from HELIOS-A now serve as a second example of the potential for RNAi therapeutics to have a meaningful impact for patients, showing the ability to halt and potentially even reverse polyneuropathy manifestations of the disease. Furthermore, our robust development program, including the APOLLO-B and HELIOS-B studies, investigates the potential of patisiran and vutrisiran, respectively, to treat the cardiac manifestations of disease across a broad spectrum of patients with ATTR amyloidosis, said John Maraganore, Ph.D., Chief Executive Officer of Alnylam. We believe that our ATTR amyloidosis franchise will be a significant driver of Alnylams growth in the years to come, with the potential to position Alnylam as a top tier biopharma company.

Vutrisiran has been granted Orphan Drug Designation in the United States and the European Union for the treatment of ATTR amyloidosis. Vutrisiran has also been granted a Fast Track designation in the United States for the treatment of the polyneuropathy of hATTR amyloidosis in adults. The safety and efficacy of vutrisiran are being evaluated in the comprehensive HELIOS clinical development program and have not yet been evaluated by any health authority. The ongoing HELIOS-B Phase 3 clinical trial in patients with ATTR amyloidosis with cardiomyopathy was initiated in late 2019 and is currently enrolling at sites around the world. Together, the HELIOS-A and -B studies are intended to demonstrate the broad impact of vutrisiran across the multisystem manifestations of disease and the full spectrum of patients with ATTR amyloidosis.

About hATTR AmyloidosisHereditary transthyretin (TTR)-mediated amyloidosis (hATTR) is an inherited, progressively debilitating, and often fatal disease caused by mutations in the TTR gene. TTR protein is primarily produced in the liver and is normally a carrier of vitamin A. Mutations in the TTR gene cause abnormal amyloid proteins to accumulate and damage body organs and tissue, such as the peripheral nerves and heart, resulting in intractable peripheral sensory-motor neuropathy, autonomic neuropathy, and/or cardiomyopathy, as well as other disease manifestations. hATTR amyloidosis, represents a major unmet medical need with significant morbidity and mortality affecting approximately 50,000 people worldwide. The median survival is 4.7 years following diagnosis, with a reduced survival (3.4 years) for patients presenting with cardiomyopathy.

About VutrisiranVutrisiran is an investigational, subcutaneously administered RNAi therapeutic in development for the treatment of ATTR amyloidosis, which encompasses both hereditary (hATTR) and wild-type (wtATTR) amyloidosis. It is designed to target and silence specific messenger RNA, blocking the production of wild-type and variant transthyretin (TTR) protein before it is made. Quarterly administration of vutrisiran may help to reduce deposition and facilitate the clearance of TTR amyloid deposits in tissues and potentially restore function to these tissues. Vutrisiran utilizes Alnylams Enhanced Stabilization Chemistry (ESC)-GalNAc-conjugate delivery platform, designed for increased potency and high metabolic stability that allows for infrequent subcutaneous injections. The safety and efficacy of vutrisiran have not been evaluated by the U.S. Food and Drug Administration, European Medicines Agency or any other health authority.

About RNAiRNAi (RNA interference) is a natural cellular process of gene silencing that represents one of the most promising and rapidly advancing frontiers in biology and drug development today. Its discovery has been heralded as a major scientific breakthrough that happens once every decade or so, and was recognized with the award of the 2006 Nobel Prize for Physiology or Medicine. By harnessing the natural biological process of RNAi occurring in our cells, a new class of medicines, known as RNAi therapeutics, is now a reality. Small interfering RNA (siRNA), the molecules that mediate RNAi and comprise Alnylams RNAi therapeutic platform, function upstream of todays medicines by potently silencing messenger RNA (mRNA) the genetic precursors that encode for disease-causing proteins, thus preventing them from being made. This is a revolutionary approach with the potential to transform the care of patients with genetic and other diseases.

About Alnylam PharmaceuticalsAlnylam (Nasdaq:ALNY) is leading the translation of RNA interference (RNAi) into a whole new class of innovative medicines with the potential to transform the lives of people afflicted with rare genetic, cardio-metabolic, hepatic infectious, and central nervous system (CNS)/ocular diseases.

SpaceX Cargo Dragon Returning To Earth; First U.S. Commercial Cargo Craft To Return From ISS – Science Times

Posted: January 8, 2021 at 3:49 pm

(Photo: Bill Ingalls/NASA via Getty Images)CAPE CANAVERAL, FL - JUNE 03: In this handout provided by the National Aeronautics and Space Administration (NASA), the SpaceX Falcon 9 rocket, with the Dragon spacecraft onboard, launches from pad 39A at NASA's Kennedy Space Center on June 3, 2017, in Cape Canaveral, Florida. Dragon is carrying almost 6,000 pounds of science research, crew supplies, and hardware to the International Space Station in support of the Expedition 52 and 53 crew members.

The National Aeronautics and Space Administration (NASA) has confirmed that on January 11, Elon Musk's SpaceX Cargo Dragon would return to Earth from the International Space Station (ISS). The said spacecraft is bringing orbital science analysis observations and other items.

Cargo Dragon embarked on a SpaceX Falcon 9 onDecember 7and landed at the ISS with at least 6,400 pounds of hardware, research samples, and crew supplies roughly 24 hours later.

In apress release, NASA said the spacecraft would make parachute-assisted water landing in the Atlantic Ocean off Florida's coast about 9:00 pm EST. NASA will broadcast the flight and landing live on theirwebsite.

Some of the scientific investigations Dragon will return to Earth include:

Microgravity induces modifications in the human heart's function and shape, and it is still unclear if these changes will become permanent if an individual stayed in space for more than a year. Using 3D-engineered cardiac tissues, a form of tissue chip, Cardinal Heartstudieshow variations in gravity influence cardiovascular cells at the cellular and tissue stage. The findings could include a new view of Earth's cardiac diseases, help detect new therapies, and facilitate the creation of cardiovascular risk prediction screening measures before spaceflight.

This Japan Aerospace Exploration Agency (JAXA) study shows human stem cell 3D organ buds' development to examine gene expression improvements. To attain 3D growth, cell cultures on Earth require supporting materials or powers. Still, without such instruments, cell cultures may extend into three dimensions in microgravity. The findings of this study could reveal the benefits of utilizing microgravity for state-of-the-art advances in regenerative medicine and could lead to the advancement of the technology required to manufacture artificial organs.

Return to Earth would be the sextant used in theSextant Navigationresearch. Sextants have a tiny telescope-like optical sight to take exact angles across pairs of stars from land or sea. It allows movement without mechanical aids. For decades, travelers have navigated through sextants, and NASA's Gemini missions performed the first spacecraft sextant sightings. This investigation evaluated basic methods for using a sextant for disaster management on satellites such as NASA's Orion, which would bring humans on deep-space flights.

The role of lungs, nerves, and lymphatic systems in the eye and improvements in mice's retina before and after spaceflight was observed in this experiment. The goal is to understand why visual perception is affected by these improvements. On long-duration space missions, at least 40 percent of astronauts suffer visual disorder known as Spaceflight-Associated Neuro-ocular Syndrome (SANS), which could negatively impact mission performance.

Using dynamically heated and cooled amine beds, thistechnologytested a process to extract carbon dioxide (CO2) from the air aboard the International Space Station. Controlling the station's CO2 levels decreases crew members' risk of developing CO2 buildup effects, including nausea, headache, trouble breathing, strained eyes, and itchy hands.

In microgravity, bacteria and other microorganisms have grown as biofilm populations. Thisexperimentdescribes the bacterial genes used during biofilms development and investigates whether stainless steel can be corroded by these biofilms, and assess a silver-based disinfectant's efficacy. This research could offer insight into better methods of managing and eliminating resistant biofilms, leading to potential space flights of long duration.

Buoyed by study, scientists increasingly hopeful first two COVID-19 vaccines effective against new strains – The Boston Globe

Posted: January 8, 2021 at 3:49 pm

David Montefiori, a Duke University virologist who is beginning to test the effectiveness of both vaccines against the British strain with help from Weissman, was also encouraged. Nonetheless, he said the Pfizer-BioNTech study was somewhat limited because it only focused on one mutation.

The British strain, he explained, has eight mutations on the spike protein the part of the coronavirus that the pathogen uses to invade a cell that distinguish it from the dominant virus in the pandemic. The same is true of the South African variant, although some mutations differ between the two.

The mutation [Pfizer-BioNTech] studied ... is the one scientists were most concerned about because of where it is located on the Spike protein, Montefiori said in an e-mail. However, it is important to get a more definitive answer with the complete variant containing all 8 mutations.

Montefiori and Weissman are studying how effective both vaccines are against the complete British variant, Montefiori said. Researchers at the National Institute for Communicable Diseases in South Africa are doing the same with the strain that emerged in their country, he added. Montefiori hoped results would be released within a couple of weeks.

The Pfizer-BioNTech findings appeared on a pre-print server and have yet to be subjected to peer review. They indicate the key mutation in both strains does not create resistance to the immune response stimulated by the Pfizer vaccine, according to a statement by the partnership.

The companies and the University of Texas Medical Branch, which participated in the study, acknowledged more research is needed to determine if the vaccine protects recipients against the two new strains.

Researchers used blood samples taken from 20 people who were vaccinated in Pfizer-BioNTechs late-stage clinical study, and mixed them with the virus containing the key mutation.

The new coronavirus variants have rattled people around the world.

The website of the Centers for Disease Control and Prevention identifies three coronavirus variations from the dominant strain: one first detected in September and now highly prevalent in London and southeast England; another first detected in October in South Africa; and a third recently isolated in Nigeria.

There is no evidence that the three variants cause more severe illness, according to the CDC, but they have led to tighter restrictions.

Prime Minister Boris Johnson on Monday announced a new national lockdown for England until at least mid-February to combat the new variant. He said people must stay home, as they were ordered to do so in the first wave of the pandemic in March, because the new strain was spreading in a frustrating and alarming way.

The British variant has been detected in parts of the United States, including California, Colorado, Connecticut, Florida, Georgia and New York. Governor Charlie Baker on Tuesday urged residents to redouble their efforts to control the spread of the coronavirus based on the assumption that the British strain has arrived in Massachusetts, although public health officials have not confirmed that.

The South African strain has not been detected in the United States. But Dr. Scott Gottlieb, the former head of the Food and Drug Administration in the Trump administration, said in an interview on CNBC on Tuesday that it appears to be prevalent in South America and he was worried that it will soon spread in the United States. He also said current medical treatments might not work as well against it, making vaccinations more urgent than ever.

The World Health Organization said Tuesday that the strain in the United Kingdom has been detected in a small number of cases in 40 other countries and areas and that the South African variant has been found in six other countries and areas.

The Pfizer-BioNTech and Moderna vaccines were about 95 percent effective at preventing the dominant strain of COVID-19 in large late-stage clinical trials, according to data released by the FDA. Each vaccine requires two shots a few weeks apart.

Weissman, an immunologist with a medical degree and PhD from Boston University whose lab licensed messenger RNA technology used by both vaccines, had already been optimistic that they would prove effective against new variants.

His reason: The coronavirus strain that has locked down much of the world for the past 10 months, he said, is actually a mutation of the original virus first identified in Wuhan, China, last December. The Moderna and Pfizer vaccines were custom-made to prevent the Wuhan strain, he added, but demonstrated even better results against the second coronavirus strain, according to a recently published study he co-authored with Montefiori and other researchers in the journal Cell Host & Microbe.

Im pretty confident they will be effective against the latest variants, Weissman, 61, told the Globe earlier this week. The spike [protein] is a very big protein, and it has many regions that antibodies can neutralize, so the mutations might affect a few small areas, but theyre not going to change the entire protein to make it resistant.

The Pfizer and Moderna vaccines rely on synthetic messenger RNA -- technology that Weissman has worked on for about 25 years -- to instruct cells to build the spike protein after people are vaccinated. When cells make the distinctive protein, it stimulates an immune response that protects people from the virus.

The emergence of new coronavirus strains comes as no surprise to scientists. When a virus replicates itself inside a cell that it has infected, the copies often have small differences because of errors, and those errors can lead to mutant strains. People get influenza shots every year because new variants emerge after such errors.

The coronavirus replication enzymes are less prone to errors than those of viruses like influenza virus, but still quite prone to errors, Pfizer said in a statement this week.

Ray Jordan, a Moderna spokesman, said his company is also testing its vaccine against several variants, but he had no details.

Weissman has studied messenger RNA since the 1990s with Katalin Kariko, a colleague at Penn who joined BioNTech, Pfizers German partner, in 2013 as senior vice president. After years of trial and error, they figured out a way to create a form of messenger RNA that could sneak its way into cells without being destroyed by the bodys natural defenses.

Derrick Rossi, a stem cell biologist who helped found Moderna in 2010, recently told the Globe that he believes the groundbreaking work of Kariko and Weissman deserves the Nobel Prize in chemistry.

Weissman, whose laboratory has developed a potential COVID-19 vaccine for the government of Thailand, said he would worry about new strains if they proved more deadly. But that hasnt happened where they have spread.

COVID-19 has caused more than 366,000 deaths in the United States, and the mortality rate is averaging under 2 percent.

If the mortality rate suddenly increased to 10 percent [as a result of new strains], thats a big problem, Weissman said.

George Lyon: Covid vaccine highlights need to accept genetic engineering – Press and Journal

Posted: January 8, 2021 at 3:48 pm

Precious few tears would have been shed on Hogmanay for the passing of 2020.

Celebrating New Year virtually imprisoned in our homes by Government decree was unimaginable this time last year.

2020 will be remembered as one of the most difficult and challenging years we have ever faced.

Millions have lost their lives, economies have been wrecked, businesses closed and jobs lost all because of a virus that jumped from animals to humans in a Chinese wet market.

Looking back what strikes me most is how well people have adapted to cope with the threat from the virus.

We have learned to live with social distancing and to disinfect our hands everywhere we go.

But by far the most difficult change to cope with is being unable to mix with our family and friends.

At work huge swathes of the population overnight found themselves working from their living rooms instead of going to their offices leaving city centres deserted and empty.

Teams and Zoom have become the mainstay of doing business and even farmers have adapted to this new-fangled digital world.

At AHDB we were forced to move our monitor farms online and to our surprise the number of farmers taking part or watching after far surpassed the numbers who would have attended an actual event.

The crisis has also brought home to consumers that supermarket shelves groaning with every kind of food available 24 hours a day are not a given.

In the early days of lockdown people were panic buying and there was a real danger of food shortages.

The food industry showed how strong, resilient and robust its supply chain is by quickly responding to meet the huge switch in consumer demand as people were forced to cook at home instead of eating out.

I would like to think that experience has made consumers recognise that farmers and growers who work seven days a week to put food on our tables are just as important as those who work in the health service and care sector.

The outlook for the New Year would have been pretty bleak if our scientists had not come up trump with new vaccines.

Developing a vaccine to fight this virus only 10 months after the outbreak started is nothing short of miraculous.

At the heart of that miracle is genetic engineering which allowed scientists to precisely construct an effective vaccine that works.

The precision of the technology was summed up for me when one of the virus experts was recently asked on the BBC if the vaccine would work on the new variant of the virus.

He said: The genetic code is like an email; we just go in and precisely adjust a few letters in it to reflect the change in the virus.

These genetically engineered vaccines will literally save millions of lives, allow economies and businesses to thrive again and save jobs.

Yet these precision genetic techniques, which have the potential to revolutionise crop breeding and vaccine development for animals, are being denied to the farming industry by the SNP Government.

Surely it is time our politicians used their common sense, ended the hypocrisy and recognised these tools are part of the solution in the move to a more sustainable agriculture.
