ABIVAX is currently developing ABX196, a state of the art immune enhancer candidate based on iNKT activation. This product is largely derived from the technology and exclusive patent rights transferred to ABIVAX by the Scripps Research Institute (La Jolla, CA), the University of Chicago (Chicago, IL) and the Brigham Young University (Salt Lake City, UT)

A phase I clinical trial in healthy volunteers has been completed and showed activation of iNKT cells. Based on these data, new immuno-oncology pre-clinical studies were conducted that demonstrated the potential of the product in oncology, in particular in turning tumors not responsive to anti-PD-1 (cold) to tumors responsive to anti-PD-1 (hot). As ABIVAX is focusing on the antiviral and anti-inflammatory therapeutic spaces and does not intend to play a role in the immune-oncology field, ABIVAX is seeking to out-license this interesting product candidate.

The characteristics of ABX196 are as follows:

ABX196 has been developed from a platform technology proprietary to ABIVAX that identifies "iNKT Agonists" that demonstrate immune enhancing effects in cancer models
ABX196 is a synthetic agonist (glycolipid) of iNKT (invariant Natural Killer T) cells, in a liposomal formulation
ABX196 is well characterized, with stability studies and full toxicity package (including non-human primate studies) conducted prior to the phase I clinical trial in healthy volunteers
Phase I showed ABX196 is well tolerated and triggered both humoral as well as iNKT immune responses in human volunteers
Pre-clinical data show that ABX196 enhances anti-tumoral activity when used alone and in combination with anti-PD-1 antibody, doxorubicin or sorafenib
ABX196 turns a cold (i.e. non-responding to anti-PD-1 antibody) tumor into a hot, responsive tumor in the mouse melanoma model, corresponding to an increase in survival time
ABX196 potentiates the anti-tumoral response to chemotherapy (doxorubicin) in the mouse melanoma model, corresponding to an increase in survival time
ABX196 controls tumor progression in an orthotopic hepatocellular cancer model in mice, again showing a prolongation of survival
In total, POC of anti-tumoral activities has been established in four preclinical cancer models
Easy-to-use liposome formulation, with scaled-up and controlled manufacturing
Strong IP protection and FTO: 5 patent families

Amphivena Receives Orphan Drug Designation for AMV564, a Novel CD33/CD3 T-Cell Engagement Therapy for the Treatment of Acute Myeloid Leukemia

On November 29, 2017 Amphivena Therapeutics Inc., a privately held biotechnology company developing a novel CD33/CD3 T cell engager for the treatment of Acute Myeloid Leukemia (AML) and Myelodysplastic Syndromes (MDS), reported that it has received Orphan Drug Designation from the U.S. Food and Drug Administration for its lead compound AMV564 for the treatment of AML (Press release, Amphivena Therapeutics, NOV 29, 2017, View Source [SID1234522341]).

"The FDA’s designation of AMV564 as an orphan drug is an important milestone for us that will provide marketing protections and economic benefits at drug approval. Given the unique safety and efficacy profile that is emerging in the clinic, we believe our CD33-targeted T cell engager will be an important drug in the armamentarium for leukemia patients who have limited treatment options today," said Eric J. Feldman, M.D., Amphivena’s Senior Vice President of Clinical Development.

Amphivena is conducting a Phase 1 clinical study of AMV564 in relapsed or refractory AML. Amphivena plans to launch a Phase 1 clinical study in patients with MDS in early 2018. The company is also exploring the utility of AMV564 in solid tumors. In preclinical studies, this novel CD33/CD3 bispecific antibody demonstrated potent activity against AML patient samples that was independent of CD33 expression level, disease stage and cytogenetic risk. The antibody eliminated nearly all blasts from bone marrow and spleen in a stringent AML patient-derived xenograft murine model. In addition, Amphivena established a therapeutic window for AMV564 in cynomolgus monkeys, with rapid and sustained elimination of CD33-expressing cells during AMV564 dosing and rapid hematopoietic recovery following dosing.

Orphan Drug Designation is granted by the FDA Office of Orphan Drug Products to products that treat rare diseases. The FDA defines rare diseases as those affecting fewer than 200,000 people in the United States. Orphan Drug Designation provides the sponsor certain benefits and incentives, including a period of marketing exclusivity for the first marketing application, if regulatory approval is received for the designated indication, potential tax credits for certain activities and waiver of certain administrative fees.

Vedanta Biosciences Expands Network of Clinical Collaborations Supporting Development of Microbiome Therapeutics for Cancer Immunotherapy

On November 29, 2017 Vedanta Biosciences, an affiliate of PureTech Health (LSE: PRTC) developing a new category of therapies for immune-mediated and infectious diseases based on rationally designed consortia of human microbiome-derived bacteria, reported new translational medicine collaborations in cancer immunotherapy with Leiden University Medical Center and the University of South Alabama (USA) Mitchell Cancer Institute (Press release, Vedanta Biosciences, NOV 29, 2017, View Source [SID1234522340]). The Company also reported the expansion of its translational medicine collaborate on in cancer immunotherapy with NYU Langone Health and its Perlmutter Cancer Center. Researchers at these institutions have been collaborating with Vedanta Biosciences to analyze microbiome clinical data from interventional checkpoint inhibitor studies to identify microbiome signatures associated with response to immunotherapy and key mechanisms through which the gut microbiota modulate immunotherapeutic responses.

"Data from our ongoing clinical collaborations in melanoma show that gut bacteria signatures could help determine if a cancer immunotherapy will work," said Bruce Roberts, Ph.D., Chief Scientific Officer of Vedanta Biosciences. "We’re pleased to expand our research collaborations into others forms of cancer, with the ultimate goal of identifying ways to change the microbiome to increase the proportion of patients and types of cancer patients who respond to immunotherapies."

Under the agreement with Leiden University Medical Center, Vedanta Biosciences will work in collaboration with Ellen Kapiteijn, M.D., Ph.D., and Ed Kuijper, M.D., Ph.D., to understand the role of the microbiome in immunotherapeutic responses against a variety of cancers, including melanoma, head and neck, and bladder. The new collaboration with the USA Mitchell Cancer Center, led by Art Frankel, M.D., will analyze associations between the gut microbiome and responses to checkpoint inhibitor treatment in melanoma and cancers of the bladder and kidneys. Building on the existing translational work with NYU Langone in melanoma led by Jeffrey S. Weber, M.D., Ph.D., and Melissa Wilson, M.D., Ph.D., the expanded agreement adds collaborations in bladder cancer and lung cancer, led, respectively, by Arjun V. Balar, M.D., and Leena Gandhi, M.D., Ph.D.

Vedanta Biosciences’ immuno-oncology programs include lead product candidate, VE800, which has been shown in preclinical models to activate CD8+ T cells, a type of white blood cell that is the predominant effector in cancer immunotherapy, improve CD8+ T cell tumor infiltration, and improve survival in several cancer models in combination with checkpoint inhibitors. Vedanta anticipates filing an investigational new drug application (IND) for this candidate in 2018.

U.S. FDA GRANTS FAST TRACK DESIGNATION FOR IDERA PHARMACEUTICALS’ IMO-2125 IN COMBINATION WITH IPILIMUMAB FOR TREATMENT OF PD-1 REFRACTORY METASTATIC MELANOMA

On November 29, 2017 Idera Pharmaceuticals, Inc. (NASDAQ:IDRA), a clinical-stage biopharmaceutical company developing toll-like receptor and RNA therapeutics for patients with rare cancers and rare diseases, reported that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation for the company’s lead development candidate IMO-2125 in combination with Ipilimumab for the treatment of anti-PD-1 refractory metastatic melanoma in combination with ipilimumab therapy (Press release, Idera Pharmaceuticals, NOV 29, 2017, View Source [SID1234522339]). FDA’s Fast Track program is designed to expedite the development and review of drugs and biologics to treat serious or life-threatening conditions with non-clinical or clinical data demonstrating the potential to address unmet medical needs. Such drugs may qualify for Fast Track designation.1

"This Fast Track designation represents another positive step for the development of IMO-2125 and is a clear recognition of the serious unmet need that exists for patients who do not benefit from anti-PD-1 therapy," stated Joanna Horobin, M.B., Ch.B., Idera’s Chief Medical Officer. "We’re thrilled with the dramatic response rate that has been observed to date so far with IMO-2125 in combination with ipilimumab and are eager to continue enrolling more patients through both the Phase 2 expansion of our ongoing trial and initiating the Phase 3 trial early next year."

About Fast Track Designation1
Fast Track designation is intended to facilitate development and expedite review of drugs to treat serious or life-threatening conditions. A drug that is intended to treat a serious or life-threatening condition with nonclinical or clinical data that demonstrate the potential to address an unmet medical need may qualify for Fast Track designation. When Fast Track designation is requested later in development, available clinical data should demonstrate the potential to address an unmet medical need. There are opportunities for frequent interactions with the review team for a fast track product. In addition, such a product could be eligible for priority review if supported by clinical data at the time of BLA, NDA, or efficacy supplement submission.

About IMO-2125
IMO-2125 is a toll-like receptor (TLR) 9 agonist that received orphan drug designation from the FDA in 2017 for the treatment of melanoma Stages IIb to IV. It signals the immune system to create and activate cancer-fighting cells (T-cells) to target solid tumors in refractory melanoma patients. Currently approved immuno-oncology treatments for patients with metastatic melanoma, specifically checkpoint inhibitors, work for some but not all, as many patients’ immune response is missing or weak and thus they do not benefit from the checkpoint therapy making them so-called "refractory." The combination of ipilimumab and IMO-2125 appears to activate an immune response in these patients who have exhausted all options. Intratumoral injections with IMO-2125 are designed to selectively enable the T-cells to recognize and attack cancers that remained elusive and unrecognized by the immune system exposed to checkpoint inhibitors alone, while limiting toxicity or impact on healthy cells in the body.

About Metastatic Melanoma
Melanoma is a type of skin cancer that begins in a type of skin cell called melanocytes. As is the case in many forms of cancer, melanoma becomes more difficult to treat once the disease has spread beyond the skin to other parts of the body such as the lymphatic system (metastatic disease). Because melanoma occurs in younger individuals, the years of life lost to melanoma are also disproportionately high when compared with other cancers. Although melanoma is a rare form of skin cancer, it comprises over 75% of skin cancer deaths. The American Cancer Society estimates that there were approximately 76,000 new invasive melanoma cases and 10,000 deaths from the disease in the USA in 2016. Additionally, according to the World Health Organization, about 132,000 new cases of melanoma are diagnosed around the world every year.

TRACON Doses First Patient in Phase 1b Study of TRC105 with Opdivo® in Patients with Lung Cancer

On November 29, 2017 TRACON Pharmaceuticals (NASDAQ:TCON), a clinical stage biopharmaceutical company focused on the development and commercialization of novel targeted therapeutics for cancer, wet age-related macular degeneration (AMD) and fibrotic diseases, reported that the first patient has been dosed in its Phase 1b clinical trial of TRC105 in combination with Opdivo (nivolumab) in patients with non-small cell lung cancer (Press release, Tracon Pharmaceuticals, NOV 29, 2017, View Source;p=RssLanding&cat=news&id=2319234 [SID1234522312]).

"Endoglin is expressed on activated myeloid derived suppressor cells, a cell type implicated in tumor resistance to immunotherapy. To date, we have observed promising signs of activity with our endoglin antibodies in combination with PD-1 inhibitors in a number of preclinical syngeneic mouse tumor models," said Charles Theuer, M.D., Ph.D., President and CEO of TRACON. "We are excited to advance a combination of TRC105 with an immune oncology agent into the clinic to further assess our antibody’s immunomodulatory activity."

About the Phase 1b Clinical Trial of TRC105 and Opdivo in Lung Cancer

The Phase 1b clinical trial is an open-label, dose-escalation and expansion cohort study of TRC105 and Opdivo in patients with non-small cell lung cancer that have received prior chemotherapy. The primary objectives of the Phase 1b study are to assess the safety of TRC105 when given with Opdivo, determine its recommended Phase 2 dose with Opdivo and evaluate the response rate. The trial incorporates tumor biopsy testing to correlate tumor myeloid cell infiltration with response, in order to allow for potential biomarker-directed therapy of lung cancer patients.

Further details of the study are available on www.clinicaltrials.gov, identifier NCT03181308.

About Carotuximab (TRC105)
