Concurrent with the financing, Steve Potts, Ph.D., MBA, founder and chief executive officer of OncoMyx, Kanad Das, Ph.D., representing BIVF, Tim Xiao, CFA, FRM, representing Delos Capital, Jason Rushton, representing Xeraya Capital, and Grant McFadden, Ph.D., founder and research advisor, have joined OncoMyx’s board of directors. Drs. Potts and Das and Messrs. Xiao and Rushton have extensive experience in the biopharmaceutical industry with track records of success. In addition to his role as Center Director and Professor of the Biodesign Center for Immunotherapy, Vaccines and Virotherapy at ASU, Dr. McFadden has pioneered the MYXV field and is widely regarded a top OV expert.

"This financing is a key step forward in advancing our pipeline of oncolytic immunotherapies," said Dr. Potts. "We are thrilled to have this strong team of experienced investors to provide the financial resources and guidance to build our company and advance our therapeutic pipeline with the ultimate goal of delivering new treatment options to patients."

OncoMyx’s proprietary OV platform is a unique and potentially best-in-class therapeutic approach that is backed by over 30 peer-reviewed publications by ASU Professor McFadden and his collaborators evaluating a poxvirus, MYXV, as an oncolytic agent in a wide variety of tumor models. Preclinical studies in mice and testing on cancer patient samples from the Mayo Clinic in Scottsdale have demonstrated encouraging immune responses against tumors. These data build upon the continued clinical validation of OVs and position OncoMyx’s platform to expand the boundaries of immuno-oncology (IO) cancer treatment and potentially benefit a large group of patients.

"OVs are emerging as a new pillar of cancer care to complement the effectiveness of immunotherapies such as immune checkpoint blockade," said Dr. McFadden. "The best-in-class MYXV platform is the only OV in development that is collectively a non-human pathogen, inherently immuno-stimulatory, easily multi-armed, and systemically delivered."

"We invested in OncoMyx because we believe in the potential of the myxoma-based oncolytic viruses for the treatment of solid cancers," said Dr. Das. "I look forward to working with Steve, Grant and the rest of the team to develop drugs that help improve patients’ lives across a range of malignancies."

Oncolytics Biotech ® Announces Study to Investigate Combination of Pelareorep and Avelumab in Metastatic Breast Cancer in Collaboration with Merck KGaA, Darmstadt, Germany, and Pfizer

On June 5, 2019 Oncolytics Biotech Inc. (NASDAQ: ONCY) (TSX: ONC), currently developing pelareorep, an intravenously delivered immuno-oncolytic virus, reported that the company has entered into an agreement with Merck KGaA, Darmstadt, Germany, a leading science and technology company, which operates in the US and Canada as EMD Serono, and Pfizer Inc. (NYSE: PFE) (Press release, Oncolytics Biotech, JUN 5, 2019, View Source [SID1234536908]). The agreement is to co-develop pelareorep in combination with paclitaxel and avelumab*, a human anti-PD-L1 antibody, for the treatment of hormone-receptor positive, human epidermal growth factor 2-negative (HR+ / HER2-) metastatic breast cancer. Oncolytics and Pfizer will share costs associated with the phase 2 clinical trial.

"Our co-development agreement with Merck KGaA, Darmstadt, Germany and Pfizer reflects a growing interest in the potential synergistic effect of oncolytic viruses and immune checkpoint inhibitors and provides yet another point of validation for our technology," said Dr. Matt Coffey, President and Chief Executive Officer of Oncolytics Biotech. "We believe pelareorep has broad applicability to boost the effectiveness of a range of checkpoint inhibitors across multiple cancer indications. We are excited to work with Merck KGaA, Darmstadt, Germany, and Pfizer and look forward to quickly developing the program to evaluate the efficacy and safety in metastatic breast cancer and potentially examining pelareorep in combination with other immunotherapies."

"We look forward to working with Oncolytics to assess the potential synergies of avelumab with their oncolytic virus platform to treat metastatic breast cancer." said Chris Boshoff, M.D., Ph.D., Senior Vice President and Chief Development Officer, Oncology, Pfizer.

"Through our collaboration with Oncolytics, we continue to advance our strategy to develop innovative immunotherapy combinations tackling the most challenging cancers," said Kevin Chin, Vice President, Global Clinical Development, Immuno-Oncology at the biopharma business of Merck KGaA, Darmstadt, Germany, which in the US and Canada operates as EMD Serono.

The study known as BRACELET-1 (BReast cAnCEr with the Oncolytic Reovirus PeLareorEp in CombinaTion with anti-PD-L1 and Paclitaxel) is an open label study that will enroll 45 patients into three cohorts with 15 patients per cohort: paclitaxel alone, paclitaxel in combination with pelareorep and paclitaxel in combination with both pelareorep and avelumab. The study will examine the expression of immune-related biomarkers to identify changes in T cell clonality between pre-treatment and on-therapy biopsies to confirm our previously identified biomarker and is designed to assess efficacy in terms of overall response rate at week 16 per RECIST 1.1 and iRECIST. The safety of the combination will also be evaluated. During the period of the study and for 90 days after a pre-determined interim analysis, Oncolytics may exclusively develop pelareorep in HR+ / HER2- metastatic breast cancer with Merck KGaA, Darmstadt, Germany, and Pfizer.

*Avelumab is under clinical investigation for treatment of hormone receptor-positive, human epidermal growth factor 2-negative (HR+ / HER2-) metastatic breast cancer and has not been demonstrated to be safe and effective for this use. There is no guarantee that avelumab will be approved for HR+ / HER2- metastatic breast cancer by any health authority worldwide.

About avelumab

Avelumab is a human anti-programmed death ligand-1 (PD-L1) antibody. Avelumab has been shown in preclinical models to engage both the adaptive and innate immune functions. By blocking the interaction of PD-L1 with PD-1 receptors, avelumab has been shown to release the suppression of the T cell-mediated antitumor immune response in preclinical models.3-5 Avelumab has also been shown to induce NK cell-mediated direct tumor cell lysis via antibody-dependent cell-mediated cytotoxicity (ADCC) in vitro.5-7 In November 2014, Merck KGaA, Darmstadt, Germany, and Pfizer announced a strategic alliance to co-develop and co-commercialize avelumab.

Avelumab Approved Indications

Avelumab (BAVENCIO) in combination with axitinib is indicated in the US for the first-line treatment of patients with advanced renal cell carcinoma (RCC).

The US Food and Drug Administration (FDA) granted accelerated approval for avelumab (BAVENCIO©) for the treatment of (i) adults and pediatric patients 12 years and older with metastatic Merkel cell carcinoma (mMCC) and (ii) patients with locally advanced or metastatic urothelial carcinoma (mUC) who have disease progression during or following platinum-containing chemotherapy, or have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. These indications are approved under accelerated approval based on tumor response rate and duration of response. Continued approval for these indications may be contingent upon verification and description of clinical benefit in confirmatory trials.

Avelumab is currently approved for patients with MCC in more than 45 countries globally, with the majority of these approvals in a broad indication that is not limited to a specific line of treatment.

Avelumab Important Safety Information from the US FDA-Approved Label

The warnings and precautions for avelumab (BAVENCIO) include immune-mediated adverse reactions (such as pneumonitis and hepatitis [including fatal cases], colitis, endocrinopathies, nephritis and renal dysfunction and other adverse reactions [which can be severe and have included fatal cases]), infusion-related reactions, major adverse cardiovascular events (MACE), and embryo-fetal toxicity.

Common adverse reactions (reported in at least 20% of patients) in patients treated with BAVENCIO include fatigue, musculoskeletal pain, diarrhea, nausea, infusion-related reaction, peripheral edema, decreased appetite/hypophagia, urinary tract infection and rash. Additional common adverse reactions reported in patients receiving BAVENCIO in combination with axitinib include hypertension, mucositis, palmar-plantar erythrodysesthesia, dysphonia, hypothyroidism, hepatotoxicity, cough, dyspnea, abdominal pain, and headache. Clinical chemistry and hematology laboratory value abnormalities have been reported including but not limited to grade 3-4 lymphopenia, anemia, elevated cholesterol and liver enzymes.

Peer-reviewed publications confirm the potential of Transgene’s TG4001 and TG6002

On June 5, 2019 Transgene (Paris:TNG), a biotech company that designs and develops virus-based immunotherapies for the treatment of solid tumors, reported the publication of two articles highlighting the potential of TG4001 and TG6002, two clinical-stage products, that are expected to generate new clinical data in H2 2019 (Press release, Transgene, JUN 5, 2019, View Source [SID1234536904]).

TG4001 in Gynecologic Oncology

The data confirm the potential of TG4001 (Tipapkinogen Sovacivec), administered as a monotherapy, to treat precancerous HPV-induced lesions (cervical intraepithelial neoplasia – CIN2/3).

These clinical results, with a 30-month follow up, are highly supportive of the ongoing development of TG4001 in combination with avelumab in HPV-positive cancers, including head and neck carcinomas (NCT

03260023), for which efficacy data are expected in H2 2019.

Of the 129 women randomized to TG4001 and 63 to placebo, complete resolution1 was significantly higher in the vaccine group than placebo for CIN 2/3 regardless of the 13 high-risk HPV types assayed (24% vs. 10%, p < 0.05).
Irrespective of baseline HPV infection, viral DNA clearance2 was higher in the vaccine group compared to placebo (p < 0.01).
TG4001 was well tolerated with the most common adverse events being injection site reactions.

Sierra Announces Momelotinib Granted FDA Fast Track Designation

On June 5, 2019 Sierra Oncology, Inc. (SRRA), a late-stage drug development company focused on advancing targeted therapeutics for the treatment of patients with significant unmet needs in hematology and oncology, reported that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to momelotinib, a JAK1, JAK2 and ACVR1 inhibitor, for the treatment of patients with intermediate/high-risk myelofibrosis who have previously received a JAK inhibitor (Press release, Sierra Oncology, JUN 5, 2019, View Source [SID1234536903]).

"Fast Track designation for momelotinib highlights the serious and significant unmet needs of patients with myelofibrosis who have previously received a JAK inhibitor. These patients typically suffer from uncontrolled constitutional symptoms, progressively worsening anemia often resulting in transfusion dependency, and enlarged spleens. Fast Track also recognizes the absence of FDA-approved treatments for these patients and that momelotinib has the potential to address their unmet needs," said Dr. Barbara Klencke, Chief Development Officer of Sierra Oncology. "We look forward to continuing to work closely with the FDA as we launch and conduct the MOMENTUM Phase 3 trial of momelotinib, with the goal of bringing this important therapy to patients expeditiously."

"We are very pleased that momelotinib has been granted Fast Track designation by the FDA, which further reflects the collaborative and constructive dialogue we have had with the Agency concerning the advancement of momelotinib towards potential registration," said Dr. Nick Glover, President & CEO of Sierra Oncology.

About FDA Fast Track Designation:
The Fast Track program facilitates the expedited development and review of new drugs or biologics that are intended to treat serious or life-threatening conditions and demonstrate the potential to address unmet medical needs. Fast Track designation allows for frequent communication and interactions with the review team at the FDA throughout the drug development and review process, with the goal of providing faster drug approval and greater patient access.

A drug that receives Fast Track designation is eligible for some or all of the following:

More frequent meetings with FDA to discuss the drug’s development plan and ensure collection of appropriate data needed to support drug approval
More frequent written communication from FDA about such things as the design of proposed clinical trials
Eligibility for Accelerated Approval and Priority Review, if relevant criteria are met
Rolling Review, which means that a drug company can submit completed sections of its Biologic License Application (BLA) or New Drug Application (NDA) for review by FDA, rather than waiting until every section of the NDA is completed before the entire application can be reviewed.
About MOMENTUM Phase 3 Clinical Trial:
A Randomized, Double-Blind, Phase 3 Study to Evaluate the Activity of Momelotinib (MMB) versus Danazol (DAN) in Symptomatic, Anemic Subjects with Primary Myelofibrosis (PMF), Post-Polycythemia Vera (PV) Myelofibrosis, or Post Essential Thrombocythemia (ET) Myelofibrosis who were Previously Treated with JAK Inhibitor Therapy.

Sierra plans to launch the MOMENTUM Phase 3 clinical trial in Q4 2019. The randomized double-blind trial is designed to enroll 180 myelofibrosis patients who are symptomatic and anemic and have been treated previously with a JAK inhibitor. Patients will be randomized 2:1 to receive either momelotinib or danazol. Danazol has been selected as an appropriate treatment comparator given its use to ameliorate anemia in myelofibrosis patients, as recommended by NCCN and ESMO (Free ESMO Whitepaper) guidelines. After 24 weeks of treatment, patients on danazol will be allowed to crossover to receive momelotinib.

The Primary Endpoint of the trial is the Total Symptom Score (TSS) response rate of momelotinib compared to danazol at Week 24 (99% power; p-value < 0.05). Secondary and exploratory endpoints include:

Transfusion Independence (TI) rate at Week 24 (key secondary: >90% powered; p-value < 0.05),
Splenic response rate (SRR) at Week 24 (>90% powered; p-value < 0.05),
Duration of TSS response to Week 48,
Other measures of anemia benefit, including Transfusion Dependence response rate and various measures of cumulative transfusion burden,
Patient Reported Outcome measures of fatigue and physical function.
Dr. Srdan Verstovsek, MD, PhD, Chief, Section for Myeloproliferative Neoplasms, Department of Leukemia, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center, Houston, Texas, has been named Chief Investigator of the MOMENTUM Phase 3 study.
