Puma Biotechnology Presents Interim Results of Phase II CONTROL Trial of PB272 in Extended Adjuvant Treatment of … – Business Wire (press release)

Posted: April 5, 2017 at 2:41 am

LOS ANGELES--(BUSINESS WIRE)--Puma Biotechnology, Inc. (Nasdaq: PBYI), a biopharmaceutical company, announced that interim results from a Phase II clinical trial of Pumas investigational drug PB272 (neratinib) were presented at the 2017 American Association for Cancer Research Annual Meeting (AACR) that is currently taking place in Washington, D.C. The presentation, entitled Effects of adding budesonide or colestipol to loperamide prophylaxis on neratinib-associated diarrhea in patients with HER2-positive early stage breast cancer: the CONTROL trial, was presented as a poster presentation.

The main adverse event that has been seen to date in clinical trials of neratinib is diarrhea and more specifically grade 3 diarrhea. In the Phase III ExteNET trial of neratinib as extended adjuvant treatment of HER2-positive early stage breast cancer that has previously been treated with adjuvant Herceptin, 95.4% of the patients experienced all grade diarrhea and 39.8% of the patients experienced grade 3 or higher diarrhea (there was one event of grade 4 diarrhea). The CONTROL trial is an international, open-label, Phase II study investigating the use of loperamide prophylaxis with or without other agents in the reduction of neratinib-associated diarrhea that has a primary endpoint of the incidence of grade 3 diarrhea.

In the CONTROL trial, patients with HER2-positive early stage breast cancer who had completed trastuzumab-based adjuvant therapy received neratinib daily for a period of one year. High dose loperamide prophylaxis was given for the first 2 cycles (56 days) of treatment. Initially, the loperamide dosing used was 16 mg on day 1, then 12 mg on days 2 and 3 and then 6-8 mg on days 4-56 (original dosing). The protocol was later amended to simplify the regimen such that patients took 12 mg on days 1-14 and 8 mg on days 15-56 (modified dosing). The CONTROL trial was also expanded to include two additional cohorts. One cohort received the combination of loperamide and budesonide and the other cohort received the combination of loperamide plus colestipol. Budesonide is a locally acting corticosteroid that the Company believes targets the inflammation identified in a preclinical model of neratinib-induced diarrhea and colestipol is a bile acid sequestrant that the Company believes targets the bile acid malabsorption also seen in preclinical models of neratinib-induced diarrhea.

The interim analysis of the trial presented in the poster included a total of 137 patients who received neratinib plus loperamide prophylaxis (28 patients taking the original dosing and 109 patients taking the modified dosing), 64 patients who received neratinib plus loperamide prophylaxis for 2 cycles and budesonide for 1 cycle, and 26 patients who received neratinib plus loperamide prophylaxis for 1 cycle and colestipol for 1 cycle.

The results of the trial showed that the incidence of grade 3 diarrhea for the 137 patients who received the loperamide prophylaxis was 30.7%. For the 137 patients who received the loperamide prophylaxis, the median number of grade 3 diarrhea episodes per patient was 1 and the median cumulative duration of grade 3 diarrhea was 3 days. For the 137 patients who received loperamide prophylaxis, 20.4% discontinued neratinib due to diarrhea.

For the 64 patients who received the combination of loperamide plus budesonide, the results of the trial showed that the incidence of grade 3 diarrhea was 23.4%. The median number of grade 3 diarrhea episodes per patient was 1 and the median cumulative duration of grade 3 diarrhea was 2 days. For the 64 patients who received loperamide plus budesonide prophylaxis, 9.4% discontinued neratinib due to diarrhea.

For the 26 patients who received the combination of loperamide plus colestipol, the results of the trial showed that the incidence of grade 3 diarrhea was 11.5%. The median number of grade 3 diarrhea episodes per patient was 2 and the median cumulative duration of grade 3 diarrhea was 2 days. For the 26 patients who received loperamide plus colestipol prophylaxis, no patient (0%) discontinued neratinib due to diarrhea. Further information is provided in Table 1 below:

In the ExteNET trial, higher grade (grade 2 and grade 3) diarrhea occurred early and persisted throughout the duration of the 12-month treatment period. In the CONTROL trial, in the loperamide prophylaxis, loperamide plus budesonide prophylaxis and loperamide plus colestipol prophylaxis arms, the results showed that higher grade diarrhea (grades 2 and 3) occurred early but did not typically recur. This is shown in more detail in Figure 1: Treatment Emergent Diarrhea, which is attached to this news release. In addition, a full copy of the poster that was presented at AACR is available on the Puma Biotechnology website.

During the course of the CONTROL trial there has been an increase in the proportion of patients previously treated with pertuzumab (mainly in the neoadjuvant setting). For the 55 patients in the loperamide prophylaxis cohort who received prior pertuzumab, the grade 3 diarrhea rate was 38.2% (Table 2). For the 82 patients who did not receive prior pertuzumab, the grade 3 diarrhea rate was 25.6%. For the 39 patients in the budesonide cohort who received prior pertuzumab, the grade 3 diarrhea rate was 10.3%. For the 25 patients in the budesonide cohort who did not receive prior pertuzumab, the grade 3 diarrhea rate was 36.0%. This analysis suggests that prior pertuzumab exposure may have led to a higher rate of grade 3 diarrhea in the CONTROL trial that was not effectively managed by loperamide prophylaxis alone but was more effectively managed by loperamide plus budesonide.

Dr. Carlos H. Barcenas, Assistant Professor, Department of Breast Medical Oncology and Associate Medical Director, Breast Cancer Survivorship Clinic for the University of Texas MD Anderson Cancer Center, said, We are pleased to see the reduction in incidence, severity and duration of neratinib-associated diarrhea when using the three antidiarrheal prophylaxis regimens tested so far in this study. When using either the loperamide prophylaxis, the loperamide plus budesonide prophylaxis or the loperamide plus colestipol prophylaxis, there appears to be a reduction in the incidence and severity of grade 3 diarrhea with neratinib. Importantly, the severe grade 2 and grade 3 diarrhea, when using the prophylaxis, appears to be acute, self-limiting and manageable. Although the study is still ongoing, we are encouraged that the addition of budesonide or colestipol appears to greatly improve the tolerability of neratinib as well. We look forward to completing the loperamide plus colestipol cohort.

Alan H. Auerbach, Chief Executive Officer and President of Puma Biotechnology, said, We are pleased to see the reductions in the incidence of severe neratinib-related diarrhea in the CONTROL trial when using the loperamide, loperamide plus budesonide or loperamide plus colestipol regimens. The severe diarrhea appears to become more acute, whereby it does not typically recur after the first month. We are also very encouraged by the improvements in tolerability that have been seen to date in the budesonide and the colestipol cohorts. This is a marked improvement in tolerability over what was seen in the ExteNET trial and we look forward to continuing to monitor this in the loperamide plus colestipol cohort.

Man Receives Reprogrammed" Stem Cells From Donor In Medical … – IFLScience

Posted: April 5, 2017 at 2:41 am

Last week, a patient with blurry vision in his right eye walked into a doctors office and became the first person to receive reprogrammed stem cells from a donor to treat his age-related macular degeneration.

The patient a Japanese man in his 60s is not alone, as four other patients have been approved for the procedure by Japan's health ministry. The first medical case was reported on March 28 by Nature.

In a one-hour operation by surgeon Yasuo Kurimoto, the patient received skin cells from a human donor at Kobe City Medical Center General Hospital. The donors skin cells were reverse engineered into induced pluripotent stem (iPS) cells. These cells are often seen as a game-changer in the world of regenerative medicine as they have the ability to become almost any type of cell in the body.

In this case, the iPS cells were turned into retinal cells, which were then implanted into the retina of the patient, who has age-related macular degeneration. It is hoped the procedure will stop the progression of the disease, which can lead to blindness. The transplantis not being touted as a cure for the condition, merely a prevention methodfrom further damage.

During the procedure, the surgical team injected 50 microliters of liquid containing 250,000 retinal cells into the patients eye, according to the Japan Times. The real test, however, will be the next phase of monitoring.

What sets this transplant apart is also what makes the recovery process precarious. Doctors will need to keep a careful watch on the patient, as iPS cells from a donor are not a genetic match and could cause an immune rejection.

At this point, you might remember a similar case in 2014 with a Japanese woman at the same hospital. She also received retinal cells derived from iPS cells, however hers were taken from her own skin, not a donor's.

"A key challenge in this case is to control rejection," said Riken researcher Masayo Takahashi to the Japan Times. "We need to carefully continue treatment."

In an update, the team said the Japanese woman was doing well and her vision had not declined. They decided to change track and use donor cells for this study because it holds a more viable future for such transplants.

It's hoped, if all goes well here, that researchers can create a bank of donor stem cells. Such a future would cut down on costs and reduce wait times, as cultivating ones own cells can take several months. However, there's stillmuch to be done.

After the procedure, Takahashi told a press conference that the surgery went well. They will continue to monitor the situation and provide further updates in the future.

A Japanese man just got another person’s stem cells transplanted in … – ScienceAlert

Posted: April 5, 2017 at 2:41 am

In what's reported to be a world-first, last Tuesday, a Japanese man received a pioneering retinal cell transplant grown from donor stem cells instead of his own.

Doctors took skin cells from a donor bank and reprogrammed them into induced pluripotent stem (iPS) cells, which can be coaxed to grow into most cell types in the body.

For this procedure, the physicians grew the iPS cells into atype of retinal cell, and then injected them into the retina of the patient's right eye.

The test subject was a man in his 60s who has been living with age-related macular degeneration-a currently incurable eye disease that slowly leads to loss of vision.

If this news sounds somewhat familiar, it's because the same team of Japanese doctors successfully performed a similar transplant in 2014. But in that case, the iPS cells came from the patient's own skin, not from a donor.

The 2014 treatment involved culturing a patient's cells into a thin sheet of retinal pigment epithelium cells, which they transplanted directly under her retina.

One year later, their results showed that the patient's disease had not progressedas it would have without any treatment, and she continues to do well.

But a second case study after the 2014 success never went ahead - the researchers found genetic abnormalities in the iPS cells they had derived from an additional patient's skin. To avoid complications, the doctors fromRIKENand Kobe City Medical Centre General Hospital decided to halt the trial and refine their approach.

Now they are back with a potentially safer technique that uses cells from a donor bank. The patient who received the transplant last week is the first of five approved for a study by Japan's health ministry in February this year. It's important to note that so far this is a safety study - a precursor to a clinical trial.

As team leader Masayo Takahashi from RIKEN told a press conference, we will have to wait and see for several years until we know for sure whether last week's transplant was a complete success - which is the whole point of doing a safety study like this.

"A key challenge in this case is to control rejection. We need to carefully continue treatment," she said.

The patient will be closely observed for a year, and then receive check-ups for three more years. The main things for the team to look out for are rejection of the new retinal cells, and the development of potential abnormalities.

An editorial in Nature praises the team's cautious approach, emphasising that this work with iPS cells could pave a smoother path for other trials in the emerging field of stem cell medicine.

If donor cells turn out to be a viable option in iPS cell procedures, it would be huge for creating more affordable stem cell treatments that anyone can benefit from.

Instead of having to induce stem cells out of each individual patient's samples, doctors could go down the cheaper and quicker route of simply picking a suitable match from a donor bank.

Stem cell treatments such as this new procedure are an extremely promising avenue in medicine, but scientists are right to remain cautious and proceed slowly. Just last month a devastating case report broke the news that three women lost their eyesight by participating in a dodgy stem cell trial.

On the other hand, in 2015, an experimental stem cell treatment showed promise in multiple sclerosis (MS) patients, and just last year, stem cell injections were used to help stroke patients in recovery.

With all these exciting developments, we'll definitely be keeping an eye on further reports from the Japanese team.

Artificial thymus can produce cancer-fighting T cells from blood stem cells – Medical Xpress

UCLA researchers have created a new system to produce human T cells, the white blood cells that fight against disease-causing intruders in the body. The system could be utilized to engineer T cells to find and attack cancer cells, which means it could be an important step toward generating a readily available supply of T cells for treating many different types of cancer.

The preclinical study, published in the journal Nature Methods, was led by senior authors Dr. Gay Crooks, a professor of pathology and laboratory medicine and of pediatrics and co-director of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA, and Amelie Montel-Hagen, an associate project scientist in Crooks' lab.

The thymus sits in the front of the heart and plays a central role in the immune system. It uses blood stem cells to make T cells, which help the body fight infections and have the ability to eliminate cancer cells. However, as people age or become ill, the thymus isn't as efficient at making T cells.

T cells generated in the thymus acquire specialized molecules, called receptors, on their surface, and those receptors help T cells seek out and destroy virus-infected cells or cancer cells. Leveraging that process has emerged as a promising area of cancer research: Scientists have found that arming large numbers of T cells with specific cancer-finding receptorsa method known as adoptive T cell immunotherapy has shown remarkable results in clinical trials.

Adoptive T cell immunotherapy typically involves collecting T cells from people who have cancer, engineering them in the lab with a cancer-finding receptor and transfusing the cells back into the patient.

However, adoptive T cell immunotherapy treatments can be time-consuming, and people with cancer might not have enough T cells for the approach to work, according to Dr. Christopher Seet, the study's first author and a clinical instructor who treats cancer patients in the division of hematology-oncology at UCLA.

Since adoptive T cell immunotherapy was first used clinically in 2006, scientists have recognized that it would be more efficient to create a readily available supply of T cells from donated blood cells or from pluripotent stem cells, which can create any cell type in the body. The challenge with that strategy would be that T cells created using this approach would carry receptors that are not matched to each individual patient, which could ultimately cause the patient's body to reject the transplanted cells or could cause the T cells to target healthy tissue in addition to cancer cells.

"We know that the key to creating a consistent and safe supply of cancer-fighting T cells would be to control the process in a way that deactivates all T cell receptors in the transplanted cells, except for the cancer-fighting receptors," Crooks said.

The UCLA team used a new combination of ingredients to create structures called artificial thymic organoids that, like the thymus, have the ability to produce T cells from blood stem cells. The scientists found that mature T cells created in the artificial thymic organoids carried a diverse range of T cell receptors and worked similarly to the T cells that a normal thymus produces.

Next, the team tested whether artificial thymic organoids could produce the specialized T cells with cancer-fighting T cell receptors. When they inserted a gene that delivers a cancer-fighting receptor to the blood stem cells, they found that the thymic organoids produced large numbers of cancer-specific T cells, and that all other T cell receptors were turned off. The results suggest that the cells could potentially be used to fight cancer without the risk of T cells attacking healthy tissue.

Montel-Hagen said the artificial thymic organoid can easily be reproduced by other scientists who study T cell development. The UCLA researchers now are looking into using the system with pluripotent stem cells, which could produce a consistent supply of cancer-fighting T cells for patients in need of immediate life-saving treatment.

Durability of CAR T-cell therapy response may depend on … – Medical Xpress

Posted: April 5, 2017 at 2:41 am

April 4, 2017

Although most patients with relapsed B-cell acute lymphoblastic leukemia (B-ALL) experienced complete response after treatment with a type of CAR T-cell immunotherapy, pretreatment disease burden impacted the durability of the responses and long-term survival, according to data from a clinical trial presented here at the AACR Annual Meeting 2017, April 1-5.

"Adult patients with relapsed or refractory ALL have extremely poor outcomes, with the five-year survival rate being less than 10 percent. Therefore, there is a clear need to develop effective therapy for these patients," said Jae Park, MD, assistant attending physician at Memorial Sloan Kettering Cancer Center (MSKCC) in New York.

"To this end, we and other groups have developed and tested CD19-specific CAR T-cell therapy [19-28z CAR T-cell therapy] and have reported encouraging results, with high initial complete response rates in patients with B-ALL. However, relapses are common, even after achieving seemingly deep remission, and severe toxicities have been observed in some patients," Park noted.

Park and colleagues, therefore, retrospectively analyzed data from a prospective clinical trial that tested 19-28z CAR T-cell therapy to identify patients who benefited the most from this therapy. All of the 51 adult patients in this trial had relapsed or refractory B-ALL after one or more conventional multiagent chemotherapy.

The researchers measured disease burden prior to CAR T-cell infusion in all patients and divided them into two cohorts those who had minimal residual disease (MRD) with less than 5 percent blast cells in bone marrow (20 patients), and those who had morphologic disease, with 5 percent or more blast cells in bone marrow (31 patients).

Complete response rates in the MRD cohort and morphologic disease cohort were 95 percent and 77 percent, respectively, which was not statistically different. After a median of 18 months of follow-up, median event-free survival and overall survival could not be computed for those in the MRD cohort (because most patients were still disease-free and alive), but they were 6.3 months and 17 months, respectively, for those in the morphologic disease cohort.

The study also found that long-term survival did not improve for patients in either cohort by having a hematopoietic stem cell transplant (HSCT) after CAR T-cell therapy.

"While more patients and longer follow-up will be needed to adequately address the significance of HSTC, the result of this analysis raises a question as to whether 19-28z CAR therapy can be considered as a definitive, curative therapy rather than a bridge to stem cell transplant, at least in a subset of patients," Park noted.

"Our data suggest that incorporation of 19-28z CAR T cells at the time of MRD following first-line chemotherapy will maximize the durability of CAR T-cell mediated remissions and survival and can potentially spare these high-risk patients from HSCT, rather than waiting until they relapse morphologically and then trying CAR T-cell therapy when it is less likely to achieve a durable long-term outcome," Park added.

Patients from the MRD cohort fared well in terms of side effects as well, compared with those in the morphologic disease cohort. Two of the major side effects associated with CAR T cells, cytokine release syndrome (CRS) and neurotoxicity, occurred in 42 percent and 58 percent of the patients, respectively, in the morphologic disease cohort, compared with 5 percent and 15 percent, respectively, in those from the MRD cohort. No case of cerebral edema was observed in either cohort of this study, Park noted.

A limitation of the study is that this is a retrospective analysis and the findings will need to be validated prospectively, Park said. Further, the analysis on the impact of post-CAR allogeneic HSCT was limited by a relatively small sample size in each cohort as the study was not designed to specifically answer or address that question.

#AACR17: Study Explores Best Time to Give CAR T Cell Therapy – Memorial Sloan Kettering Cancer Center (blog)

Posted: April 5, 2017 at 2:41 am

Summary

For patients with leukemia who relapse after chemotherapy, treatment options have traditionally been limited. At MSK, an experimental immunotherapy called CAR T therapy has expandedoptions for these patients. New research data presented at this years annual meeting of the American Association for Cancer Research (AACR) suggest that patients do better on the therapy when they are treated at the time of minimal residual disease.

Highlights

Like many patients who come to Memorial Sloan Kettering, Glen Blum, 31, had already received treatment at another hospital for a cancer that was proving stubbornly hard to beat.

His saga began several years ago, when lingering back pain led to a blood test, a biopsy, and eventually a diagnosis of acute lymphoblastic leukemia, or ALL. This aggressive cancer, which grows in the bone marrow, had already damaged several of his vertebrae. He received conventional treatment with both chemotherapy and radiation, which helped for a while. But as is often the case with ALL, the cancer came roaring back. And when it did, it was resistant to further treatment with conventional drugs.

Thats when Mr. Blums doctor recommended that he enroll in a clinical trial of an experimental immunotherapy treatment at MSK. The goal of that treatment, called chimeric antigen receptor (CAR) T cell therapy, would be to shrink his cancer down to a point where he would be eligible for a potentially life-saving bone marrow transplant.

The way they explained itto me is that the treatment would get my own immune cells to see the cancer cells as foreign and eliminate them, says Mr. Blum, who lives in East Harlem in New York City. Then the bone marrow transplant was a secondary step so that I wouldnt grow more cancer cells.

The treatment would get my own immune cells to see the cancer cells as foreign and eliminate them.

Historically, a bone marrow transplant is often a leukemia patients last, best hope for a cure once initial therapy has failed. But the procedure is not without significant risks. To receive new bone marrow, patients must first have their existing bone marrow destroyed with high-dose chemotherapy or radiation. Because the bone marrow is what produces blood cells including the white blood cells that make up the immune system patients are vulnerable to infections while the new bone marrow grows. There is also the risk that immune cells from the donor marrow will start to attack the bodys healthy cells, a dangerous complication called graft-versus-host disease.

But what if it were possible for patients to receive CAR T cell therapy earlier, before a relapse? Would outcomes for these patients be better? And might they be able to forgo a bone marrow transplant altogether?

On April 3, at the AACR annual meeting, MSK physician-scientist Jae Park presented research that speaks directly to these questions. Dr. Park and his colleagues took a retrospective look at all adult patients with relapsed or refractory ALL treated with CAR T cells at MSK 51 patients in all. They wanted to understand who benefits the most from this experimental treatment. For example, does the amount of leukemia a person has at the time of CAR T therapy influence how long that person remains free of disease or how severe the side effects are?

To get at these questions, the team divided those 51 patients into two groups: those with minimal residual disease (MRD, defined as less than 5% of cancer cells in the bone marrow at the time of CAR therapy) and those with obvious morphologic disease (MD, defined as 5% or greater cancer cells in the bone marrow). They then performed statistical analyses on the two groups to determine whether they differed in terms of length of survival and severity of side effects.

What they found was that, indeed, there was a significant difference in outcomes between the two groups. Although both groups initially experienced deep regressions leading to a high rate of complete responses, patients in the MRD group lived longerand hadless toxicity compared with those in the MD group. (After an average of 18 months of follow-up, most of the MRD patients werestill alive and free of disease, while the MD patients had a median survival of 17 months; the rate of a life-threatening side effect called cytokine release syndrome was 5% for MRD patients versus 42% for MD patients.)

According to Dr. Park, the results of this study provide strong support for administering CAR T cell therapy soon after initial chemotherapy, when a patient has minimal residual disease, rather than waiting until a patient relapses. The data from this study, he says, indicate that the CAR T cell therapy is likely to be both more effective and less toxic in the earlier setting. A prospective study to test this hypothesis is currently being planned.

Our ultimate goal is to cure the disease with as little therapy as possible and with the minimum of toxicity.

Another suggestive finding though one that needs to be interpreted with caution, given the small sample size was that receiving a BMT after the CAR T therapy did not seem to improve outcomes in either group of patients. This raises the possibility that CAR T therapy might serve as a final or destination therapy, rather than as a bridge to transplant as it is typically used.

Our ultimate goal is to cure the disease with as little therapy as possible and with the minimum of toxicity, Dr. Park says. A bone marrow transplant is currently the only proven curative treatment for patients with relapsed or refractory ALL. But at the same time, its a pretty toxic therapy, and carries a mortality rate anywhere from 15% to 25%. So if we could use CAR T cell therapy to treat the disease while sparing at least some patients the risks of transplant, that would be a big improvement.

Glen Blum and his fiance, Ashley

For Mr. Blum, there was never really a question that he would go for the transplant, though he admits there was a point after the CAR T cell therapy when he considered his options.

Hearing that your cancer is at zero feels like a victory, he said. It feels like, Oh great, Im done.But then when I thought about all I went through to get to that point all the rounds of chemo and radiation, the hospital stays, the experimental treatment to not go the last mile just didnt feel right.

Yet Mr. Blums experience with bone marrow transplantation indicates why doctors are eager get to a point at which they can safely avoid it. About a month after the transplant, he got an infection that led to a severe case of pneumonia.

I was in the ICU, and honestly, it was a really scary time, Mr. Blum says. The doctorstold my mother not to leave the hospital. They were worried I might not make it.

According to Dr. Park, the decision to recommend a BMT or not becomes a question of weighing different factors, including the number of previous treatments, the characteristics of the disease, the risks of the transplant, the risk of relapse, and the age of the patient.

These are the practical conversations were having with patients every day, he says. And while Im not suggesting by any means that weve answered the question definitively, this study raises the possibility that at least for some patients CAR therapy could be an end point.

In May, it will be one year since Mr. Blum had his bone marrow transplant. Though he still has some back pain, he says he is feeling much better. Hes since gotten engaged, and he and his fiance, Ashley, are planning a trip to Jamaica in June assuming doctors give him the all-clear before then.

He says he has no regrets about the treatment he received, despite the difficulties. He always felt very well cared for at MSK.

That hospital is a piece of heaven, Mr. Blum says. Everyone there, including Dr. Park, has a heart three times the size of normal.
