The initial focus of this partnership will be the development of a companion diagnostic assay for Merrimack’s seribantumab, or MM-121, an investigational therapy. Seribantumab is a fully human, monoclonal antibody that targets ErbB3, a cell surface receptor that is activated by the ligand heregulin (HRG). Heregulin-driven ErbB3 signaling identifies a unique, more difficult to treat cancer phenotype characterized by increased tumor growth and increased resistance to targeted, cytotoxic and anti-endocrine therapies. Seribantumab is being investigated primarily in combination settings, to block HRG activated ErbB3 signaling in order to enhance the anti-tumor effect of the combination therapy partner.

"We are pleased to be working with Merrimack on cancer therapies with the BOND platform," added Matthias Weber MD, President of Leica Biosystems. "The partnership utilizing RNAscope technology is an example of Leica Biosystems paving the way for in situ RNA detection in personalized medicine. The ease of use and high quality staining delivered by BOND systems makes them ideal platforms on which to deploy these very informative tests."

"Our increased understanding of cancer cell biology is driving the need for companion diagnostic tests to ensure the right patients get the right therapies," said Jason Baum, Director, Companion Diagnostics at Merrimack. "The use of RNAscope technology on Leica Biosystems’ automated staining platforms will allow us to detect HRG with high sensitivity and specificity, helping to identify the patients most likely to benefit from seribantumab treatment. HRG is the cognate ligand of the ErbB3 receptor and a powerful driver of cell survival signaling. HRG tumor expression has been implicated in defining a distinct, difficult to treat cancer phenotype that is found across multiple solid tumors at a prevalence rate of approximately 30-50% in major indications. We are pleased to have partnered with Leica Biosystems on this project."

Leica Biosystems’ work program will be led from their Companion Diagnostics Research and Development site in Danvers, Greater Boston, Massachusetts, with kit manufacturing occurring in Newcastle.

On April 14, 2016 Oncolytics Biotech Inc. (TSX: ONC) (OTCQX: ONCYF) (FRA: ONY) ("Oncolytics" or the "Company") reported updated results for a randomized Phase 2 clinical trial of its lead product, REOLYSIN, in combination with carboplatin and paclitaxel in patients with pancreatic cancer (NCI-8601) (Filing, 6-K, Oncolytics Biotech, APR 14, 2016, View Source [SID:1234510816]).

The Company performed an intent-to-treat analysis of overall survival on patients with confirmed treatment regimes, as assessed by the percentage of patients surviving for two years. The analysis showed a statistically significantly higher percentage of patients surviving two years in the test arm versus the control arm (p = 0.001), the crossover arm versus the control arm (p = 0.03) and the test plus crossover arms versus the control arm (p = 0.0004). At the time of the data cut off (January 19, 2016), there were five survivors on study in the test arm, and one survivor on study in the crossover arm. As a result, the two- and three-year survival for the arms may continue to evolve.

"These data clearly illustrate that patients receiving REOLYSIN, whether in the test arm or crossing over after progressing in the control arm, received a benefit in longer-term overall survival," said Dr. Brad Thompson. "The overall survival findings in this study build on what we saw in our REO 017 study, where the combination of REOLYSIN and gemcitabine, also produced a clear longer-term overall survival benefit, despite having limited impact on progression free survival. This is characteristic of clinical studies where the immune system affects patient outcomes. Based on these combined results, we are currently enrolling pancreatic cancer patients in a study incorporating REOLYSIN plus the checkpoint inhibitor KEYTRUDA to determine the effect of the immune system on patient outcomes."

This was one in a series of randomized Phase 2 studies with REOLYSIN that were designed and sponsored by third parties to test their specific hypotheses, and the Company intends to use these findings to further advance its own clinical program.

Study Design Summary
The study was an open-label, multi-institution, two-arm Phase 2 randomized study of patients with metastatic pancreatic cancer. Patients were randomized to receive either carboplatin, paclitaxel and REOLYSIN (test arm) or carboplatin and paclitaxel alone (control arm). Patients in both arms received treatment every three weeks (21-day cycles) and standard intravenous doses of paclitaxel and carboplatin on day one only. In the test arm, patients also received intravenous REOLYSIN at a dose of 3×1010 TCID50 on days one through five. Tumor response was assessed by computed tomography (CT) scan and conducted every eight weeks. Patients who progressed on carboplatin and paclitaxel (control arm) had REOLYSIN added (crossover arm). If patients experienced significant toxicity related to carboplatin and/or paclitaxel, they could continue with single agent REOLYSIN.

The primary endpoint of the trial is to assess improvement in progression free survival with REOLYSIN, carboplatin and paclitaxel relative to carboplatin and paclitaxel alone in patients with metastatic pancreatic cancer. Secondary endpoints include safety, overall response rate, overall survival, immune factors and to prospectively establish and validate the relationship between Ras mutations in tumor samples and response to REOLYSIN. For this analysis, the control arm is patients receiving carboplatin and paclitaxel alone, the test arm is patients receiving carboplatin, paclitaxel, and REOLYSIN, and the crossover arm is patients initially treated with carboplatin and paclitaxel alone, who progressed and subsequently had REOLYSIN added to their treatment regime.

The NEfERT-T trial is a randomized, two-arm Phase II trial of neratinib plus the anticancer drug paclitaxel versus trastuzumab (Herceptin) plus paclitaxel as a first-line treatment for ERBB2-positive (previously referred to as HER2-positive) locally recurrent or metastatic breast cancer. The trial enrolled 479 patients in 33 countries who had not received prior anticancer therapy for locally recurrent or metastatic disease. Patients were randomized to receive first-line treatment with either paclitaxel plus neratinib or paclitaxel plus trastuzumab. The primary endpoint of the trial was progression-free survival (PFS). The secondary endpoints of the study included objective response rate (ORR) and the incidence of central nervous system (CNS) metastases, including brain metastases.

The results of the trial demonstrated that the progression-free survival for the patients who received the combination of paclitaxel plus neratinib was 12.9 months and the progression-free survival for the patients who received the combination of paclitaxel plus trastuzumab was 12.9 months (hazard ratio 1.02, p=0.89). The objective response rate in the trial for the patients who received the combination of paclitaxel plus neratinib was 74.8% and the objective response rate for the patients who received the combination of paclitaxel plus trastuzumab was 77.6% (p=0.52).

With respect to the incidence of CNS metastases (e.g., brain metastases), treatment with the combination of paclitaxel plus neratinib resulted in a 52% reduction in the incidence of CNS metastases compared to the incidence of CNS metastases in patients who received the combination of paclitaxel plus trastuzumab. Symptomatic or progressive CNS recurrences occurred in 20 patients (8.3%) in the neratinib-paclitaxel group and 41 patients (17.3%) in the trastuzumab-paclitaxel group (relative risk 0.48, p=0.002). The estimated Kaplan-Meier 2-year incidence of CNS recurrences was 16.3% in the neratinib-paclitaxel group and 31.2% in the trastuzumab-paclitaxel group (hazard ratio 0.45, p=0.004). These results reflect a statistically significant difference between the two treatment arms.

"The NEfERT-T trial represents the first randomized trial with a HER2-targeted agent that has shown a statistically significant reduction in the incidence of CNS metastases," said Alan H. Auerbach, Chief Executive Officer and President. "We believe this provides a meaningful point of differentiation for neratinib in the treatment of HER2-positive breast cancer. We are pleased that JAMA Oncology has chosen to publish these results."

On April 14, 2016 Bristol-Myers Squibb Company (NYSE:BMY) reported that the U.S. Food and Drug Administration (FDA) accepted a supplemental Biologics License Application (sBLA), which seeks to expand the use of Opdivo to patients with classical Hodgkin lymphoma (cHL) after prior therapies (Press release, Bristol-Myers Squibb, APR 14, 2016, View Source [SID:1234510769]).

The application included CheckMate -205 data, which evaluated Opdivo in cHL patients who have received autologous stem cell transplant and brentuximab vedotin. The FDA granted the application a priority review and previously granted Opdivo Breakthrough Therapy Designation for cHL on May 14, 2014. According to the FDA, Breakthrough Therapy Designation is intended to expedite the development and review of drugs for serious or life-threatening conditions.

"There is a significant burden on classical Hodgkin lymphoma patients who do not respond to initial treatment, and they need new treatment options that address the disease in a different way," said Jean Viallet, M.D., Oncology Global Clinical Research Lead, Bristol-Myers Squibb. "With the Agency’s acceptance of our application, Opdivo has the potential to be the first PD-1 inhibitor in hematology, allowing us to expand Immuno-Oncology beyond solid tumors to patients with classical Hodgkin lymphoma and strengthen our hematology franchise."

CheckMate -205 is a Phase 2 study evaluating the safety and efficacy of Opdivo in patients with relapsed or refractory cHL. Data from this trial are expected to be presented at a medical meeting later this year.

About Hodgkin Lymphoma

Hodgkin lymphoma, which also is known as Hodgkin disease, is one of two main types of lymphoma, a group of cancers most often beginning in the lymph nodes.1 Hodgkin lymphoma is characterized by malignant lymphocytes called Reed-Sternberg cells.1 The other type of lymphoma is non-Hodgkin lymphoma, which is much more common.1 Hodgkin lymphoma affects nearly 190,000 people in the United States,2 with about 8,500 new cases and 1,120 deaths expected this year.1 There remains a significant unmet need for patients who have relapsed or have become refractory to current treatments.

Bristol-Myers Squibb & Immuno-Oncology: Advancing Oncology Research

At Bristol-Myers Squibb, we have a vision for the future of cancer care that is focused on Immuno-Oncology, now considered a major treatment choice alongside surgery, radiation and chemotherapy for certain types of cancer.

We have a comprehensive clinical portfolio of investigational and approved Immuno-Oncology agents, many of which were discovered and developed by our scientists. Our ongoing Immuno-Oncology clinical program is looking at broad patient populations, across multiple solid tumors and hematologic malignancies, and lines of therapy and histologies, with the intent of powering our trials for important measures. We pioneered the research leading to the first regulatory approval for the combination of two Immuno-Oncology agents, and continue to study the role of combinations in cancer.

We are also investigating other immune system pathways in the treatment of cancer including CTLA-4, CD-137, KIR, SLAMF7, PD-1, GITR, CSF1R, IDO, and LAG-3. These pathways may lead to potential new treatment options – in combination or monotherapy – to help patients fight different types of cancers.

Our collaboration with academia, as well as small and large biotech companies, is responsible for researching the potential Immuno-Oncology and non-Immuno-Oncology combinations, with the goal of providing new treatment options in clinical practice.

At Bristol-Myers Squibb, we are committed to conducting research for hard-to-treat cancers.

About Opdivo

Cancer cells may exploit "regulatory" pathways, such as checkpoint pathways, to hide from the immune system and shield the tumor from immune attack. Opdivo is a PD-1 immune checkpoint inhibitor that binds to the checkpoint receptor PD-1 expressed on activated T-cells. It blocks the binding of PD-L1 and PD-L2, preventing the PD-1 pathway’s suppressive signaling on the immune system, including the interference with an anti-tumor immune response.

Opdivo’s broad global development program is based on Bristol-Myers Squibb’s understanding of the biology behind Immuno-Oncology. Our company is at the forefront of researching the potential of Immuno-Oncology in hard-to-treat cancers. This scientific expertise serves as the basis for the Opdivo development program, which includes a broad range of Phase 3 clinical trials. To date, the Opdivo clinical development program has enrolled more than 18,000 patients.

Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world in July 2014 and currently has regulatory approval in 48 countries, including the United States, Japan and in the European Union.

IMPORTANT SAFETY INFORMATION

WARNING: IMMUNE-MEDIATED ADVERSE REACTIONS

YERVOY can result in severe and fatal immune-mediated adverse reactions. These immune-mediated reactions may involve any organ system; however, the most common severe immune-mediated adverse reactions are enterocolitis, hepatitis, dermatitis (including toxic epidermal necrolysis), neuropathy, and endocrinopathy. The majority of these immune-mediated reactions initially manifested during treatment; however, a minority occurred weeks to months after discontinuation of YERVOY.

Assess patients for signs and symptoms of enterocolitis, dermatitis, neuropathy, and endocrinopathy and evaluate clinical chemistries including liver function tests (LFTs), adrenocorticotropic hormone (ACTH) level, and thyroid function tests at baseline and before each dose.

Permanently discontinue YERVOY and initiate systemic high-dose corticosteroid therapy for severe immune-mediated reactions.

Immune-Mediated Pneumonitis

Immune-mediated pneumonitis, including fatal cases, occurred with OPDIVO treatment. Across the clinical trial experience with solid tumors, fatal immune-mediated pneumonitis occurred with OPDIVO. In addition, in Checkmate 069, there were six patients who died without resolution of abnormal respiratory findings. Monitor patients for signs with radiographic imaging and symptoms of pneumonitis.

Immune-mediated rash can occur with OPDIVO treatment. Severe rash (including rare cases of fatal toxic epidermal necrolysis) occurred in the clinical program of OPDIVO. Monitor patients for rash. Administer corticosteroids for Grade 3 or 4 rash. Withhold for Grade 3 and permanently discontinue for Grade 4. In Checkmate 069 and 067, immune-mediated rash occurred in 22.6% (92/407) of patients receiving OPDIVO with YERVOY: Grade 3 (n=15), Grade 2 (n=31), and Grade 1 (n=46). In Checkmate 037, 066, and 067, immune-mediated rash occurred in 9% (72/787) of patients receiving OPDIVO: Grade 3 (n=7), Grade 2 (n=15), and Grade 1 (n=50). In Checkmate 057, immune-mediated rash occurred in 6% (17/287) of patients receiving OPDIVO including four Grade 3 cases. In Checkmate 025, rash occurred in 28% (112/406) of patients receiving OPDIVO and 36% (143/397) of patients receiving everolimus. Immune-mediated rash, defined as a rash treated with systemic or topical corticosteroids, occurred in 7% (30/406) of patients receiving OPDIVO: Grade 3 (n=4), Grade 2 (n=7), and Grade 1 (n=19).

Immune-Mediated Encephalitis

Immune-mediated encephalitis can occur with OPDIVO treatment. Withhold OPDIVO in patients with new-onset moderate to severe neurologic signs or symptoms and evaluate to rule out other causes. If other etiologies are ruled out, administer corticosteroids and permanently discontinue OPDIVO for immune-mediated encephalitis. In Checkmate 067, encephalitis was identified in one patient (0.2%) receiving OPDIVO with YERVOY. In Checkmate 057, fatal limbic encephalitis occurred in one patient (0.3%) receiving OPDIVO.

Other Immune-Mediated Adverse Reactions

Based on the severity of adverse reaction, permanently discontinue or withhold treatment, administer high-dose corticosteroids, and, if appropriate, initiate hormone-replacement therapy. In < 1.0% of patients receiving OPDIVO, the following clinically significant, immune-mediated adverse reactions occurred: uveitis, pancreatitis, facial and abducens nerve paresis, demyelination, polymyalgia rheumatica, autoimmune neuropathy, Guillain-Barré syndrome, hypopituitarism, systemic inflammatory response syndrome, gastritis, duodenitis, and sarcoidosis. Across clinical trials of OPDIVO as a single agent administered at doses of 3 mg/kg and 10 mg/kg, additional clinically significant, immune-mediated adverse reactions were identified: motor dysfunction, vasculitis, and myasthenic syndrome.

Infusion Reactions

Severe infusion reactions have been reported in <1.0% of patients in clinical trials of OPDIVO. Discontinue OPDIVO in patients with Grade 3 or 4 infusion reactions. Interrupt or slow the rate of infusion in patients with Grade 1 or 2. In Checkmate 069 and 067, infusion- related reactions occurred in 2.5% (10/407) of patients receiving OPDIVO with YERVOY: Grade 2 (n=6) and Grade 1 (n=4). In Checkmate 037, 066, and 067, Grade 2 infusion related reactions occurred in 2.7% (21/787) of patients receiving OPDIVO: Grade 3 (n=2), Grade 2 (n=8), and Grade 1 (n=11). In Checkmate 057, Grade 2 infusion reactions requiring corticosteroids occurred in 1.0% (3/287) of patients receiving OPDIVO. In Checkmate 025, hypersensitivity/infusion-related reactions occurred in 6% (25/406) of patients receiving OPDIVO and 1.0% (4/397) of patients receiving everolimus.

Embryo-fetal Toxicity

Based on their mechanisms of action, OPDIVO and YERVOY can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with an OPDIVO- or YERVOY- containing regimen and for at least 5 months after the last dose of OPDIVO.

Lactation

It is not known whether OPDIVO or YERVOY is present in human milk. Because many drugs, including antibodies, are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from an OPDIVO-containing regimen, advise women to discontinue breastfeeding during treatment. Advise women to discontinue nursing during treatment with YERVOY and for 3 months following the final dose.

Serious Adverse Reactions

In Checkmate 067, serious adverse reactions (73% and 37%), adverse reactions leading to permanent discontinuation (43% and 14%) or to dosing delays (55% and 28%), and Grade 3 or 4 adverse reactions (72% and 44%) all occurred more frequently in the OPDIVO plus YERVOY arm relative to the OPDIVO arm. The most frequent (≥10%) serious adverse reactions in the OPDIVO plus YERVOY arm and the OPDIVO arm, respectively, were diarrhea (13% and 2.6%), colitis (10% and 1.6%), and pyrexia (10% and 0.6%). In Checkmate 037, serious adverse reactions occurred in 41% of patients receiving OPDIVO. Grade 3 and 4 adverse reactions occurred in 42% of patients receiving OPDIVO. The most frequent Grade 3 and 4 adverse drug reactions reported in 2% to <5% of patients receiving OPDIVO were abdominal pain, hyponatremia, increased aspartate aminotransferase, and increased lipase. In Checkmate 066, serious adverse reactions occurred in 36% of patients receiving OPDIVO. Grade 3 and 4 adverse reactions occurred in 41% of patients receiving OPDIVO. The most frequent Grade 3 and 4 adverse reactions reported in ≥2% of patients receiving OPDIVO were gamma-glutamyltransferase increase (3.9%) and diarrhea (3.4%). In Checkmate 057, serious adverse reactions occurred in 47% of patients receiving OPDIVO. The most frequent serious adverse reactions reported in ≥2% of patients were pneumonia, pulmonary embolism, dyspnea, pleural effusion, and respiratory failure.
