WARF Therapeutics announces partnership with Sanford Burnham Prebys Medical Discovery Institute

On March 21, 2019 WARF Therapeutics reported a new partnership with Sanford Burnham Prebys Medical Discovery Institute (SBP) (Press release, WARF Therapeutics, MAR 21, 2019, View Source [SID1234644191]). SBP is an independent, nonprofit institution dedicated to understanding basic human biology and disease, and to advancing scientific discoveries to profoundly impact human health. SBP’s Conrad Prebys Center for Chemical Genomics (Prebys Center) is one of the most advanced drug discovery centers in the nonprofit world.

WARF Therapeutics was established as a major new program of the Wisconsin Alumni Research Foundation (WARF) in 2018. Its mission is to identify promising biological discoveries on the UW-Madison campus that are relevant to human disease. WARF Therapeutics will invest in validated targets, design and develop drug-like molecules, and ultimately partner them with the venture capital community, pharmaceutical organizations and biotech companies. Jonathan Young, Ph.D., an industry veteran with over 20 years of experience in large pharma and biotech, was recently hired, after a nationwide search, to build and lead WARF Therapeutics.

Young says, "WARF’s collaboration with SBP will help us accelerate translation of promising research by providing the essential discovery and early development expertise required. Furthermore, this partnership will help WARF Therapeutics continue the legacy of pharmaceutical innovation at UW-Madison and ultimately deliver novel medicines to patients with unmet medical needs."

Under the terms of the 5-year agreement, WARF and UW-Madison scientists will work with scientists at SBP’s Prebys Center to transition clinically relevant targets to early-stage drug discovery, including assay development and high-throughput screening to identify chemical compounds that modulate the activity of the targets. The Prebys Center’s compound library is a collection of more than 1 million diverse chemicals. Validated "hits" from this library can be developed into prototype drugs.

"The Prebys Center is like a magnet that attracts collaborators and partnerships with like-minded researchers who seek to discover new therapeutics for diseases with serious clinical unmet needs," says Michael Jackson, Ph.D., senior vice president of drug discovery and development at SBP. "We look forward to a productive partnership with WARF that will lead to therapies for diseases in need of a cure."

SBP holds an analogous partnership with the Mayo Clinic that began in 2012. The Mayo-SBP agreement outlines efforts to build a pipeline of therapeutic drugs aimed at a variety of diseases with serious unmet clinical needs.

Celgene and Exscientia enter 3-year AI drug discovery collaboration focused on accelerating drug discovery in oncology and autoimmunity

On March 21, 2019 Exscientia, a world-leading Artificial Intelligence (AI)-driven drug discovery company, reported that it has entered a three-year AI drug discovery partnership with leading biopharma company Celgene, including an initial $25 million upfront payment and eligibility to receive substantial milestones based on the clinical, regulatory and commercial success of the program (Press release, Exscientia, MAR 21, 2019, View Source [SID1234553912]). In addition, Exscientia is due to receive tiered royalties on net sales on any product resulting from the collaboration. Exscientia will apply its full-stack AI drug discovery capabilities to the execution of the entire project – from gene to the drug candidate.

The collaboration will use AI to accelerate the discovery of small molecule therapeutic drug candidates for three therapeutic programmes for Celgene in the areas of oncology and autoimmunity.

Exscientia will use its cutting-edge Centaur Chemist AI drug discovery platform, which has demonstrated its unparalleled capabilities on multiple projects and its ability to reduce the timelines by at least three-quarters to discover pre-clinical drug candidates. Applying AI to improve the speed of delivery of new treatments for patients is a key goal of this collaboration.

This deal extends Exscientia’s list of partnerships with blue chip pharma and biotech companies, with existing collaborations involving Roche, GSK, Sanofi and Evotec, cementing Exscientia’s reputation as the partner of choice in the rapidly developing field of AI-driven drug discovery. At the start of this year, the Oxford based Exscientia secured a $26 million Series B investment to expand its capabilities, develop its platform and build its proprietary drug pipeline.

Professor Andrew Hopkins, CEO of Exscientia, commented: "We’re incredibly proud to collaborate with Celgene and to sign another partnership with a key industry player, reinforcing our place at the forefront of AI drug discovery. Today, patients can wait more than ten years from initial drug discovery to its availability as a treatment. With autoimmune diseases and cancer rates increasing, the pharmaceutical industry’s R&D productivity needs to dramatically improve – and technology is a key part of this. Since our pioneering Nature papers in the field, we have been developing our AI platform on the principle that AI combined with human creativity can significantly accelerate the drug discovery process and thus drastically improve access of new drugs to the market. We’re excited to work with Celgene to drive this transformational change in new therapeutic areas."

Epic Sciences to Present New Data at AACR 2019 Demonstrating Expansion of Functional Cell Profiling Technology into New Indications including Breast, Lung and Prostate Cancer

On March 21, 2019 Epic Sciences, Inc. reported that new data will be presented at the American Association of Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2019, in Atlanta, Georgia, March 29 to April 4, 2019 (Press release, Epic Sciences, MAR 21, 2019, View Source [SID1234534564]). The data from multiple studies and indications demonstrate the feasibility of Epic’s Functional Cell Profiling (FCP) technology to predict patients’ response to cancer immunotherapies and drugs that target DNA damage repair pathways.

Epic’s FCP technology platform identifies and characterizes all circulating tumor cells in a blood sample to link their response or resistance to several drug classes. Following the highly successful development of Epic’s proprietary AR-V7 test for patients with metastatic castration-resistant prostate cancer, currently marketed as the Oncotype DX AR-V7 Nucleus Detect test, the company and its research partners are utilizing the FCP platform to analyze biomarkers to guide treatment decisions in breast cancer and small-cell lung cancer, expanding into new areas of unmet need.

"For years, Epic Sciences has been transforming late-stage prostate cancer treatment with our powerfully predictive Functional Cell Profiling technology by providing a comprehensive view of how populations of cancer cells change under selective pressure of different drug classes," said Katherine Atkinson, Chief Commercial Officer at Epic Sciences. "At AACR (Free AACR Whitepaper), we are presenting new data that demonstrates our technology’s significant value can be applied to new indications and drug classes in development, in addition to late stage prostate cancer, potentially improving the lives of many more patients."
