The Lead Investigator of this up to 40 patients trial is Professor Doctor Salah-Eddin Al-Batran, the Medical Director of the IKF. The study will commence subject to receiving the necessary approvals from the competent regulatory authority and ethics committee.
Dr Al-Batran commented: "The promising results from previous studies and favourable safety profile of IMP321 have led us to conduct a phase I trial investigating a potential enhancement of the immune-activating effects of IMP321 by new routes of administration. Furthermore, we will explore the possibility to extend the positive results obtained by subcutaneous injections of IMP321 in metastatic renal cell and breast carcinomas to further solid tumour entities."

Marc Voigt, Chief Executive of Prima, said: "This is potentially an exciting new therapeutic application for IMP321 and is the result of the extensive research carried out by Dr Frédéric Triebel and the Prima team in our Paris laboratory. It is the first ever investigation into whether direct injection of IMP321 into a solid tumour can activate the antigen presenting cells located inside the tumour to boost the body’s immune response. As this trial is investigator initiated, it will also not require any significant near-term resource commitment from Prima."

Evelo and Epiva were both founded by Flagship’s VentureLabs innovation foundry in 2014 and followed the lineage of prior VentureLabs-founded microbiome companies Seres Therapeutics (launched in 2012) and Indigo Agriculture (launched in 2013). The Evelo-Epiva merger results in a 42-person company and combines each team’s pioneering research findings, product candidates and intellectual property protected by over 50 patents and applications. Flagship has financed the company with about $40 million to date and plans to make additional investments to support its rapid growth.

The combined entity establishes the definitive immuno-microbiome therapeutics platform, building upon both organizations’ recognition that the microbiome and immune system interact to form a largely unrecognized and uncharacterized metasystem, the immuno-microbiome. Evelo is at the forefront of deciphering the interactions between the immune system and the microbiome to discover novel therapeutics.

"The immune system functions in the context of its interactions with the microbiome and vice versa. Deciphering these interactions presents significant opportunities to develop new medicines for patients across multiple disease areas, including next wave cancer immunotherapy and treatment for autoimmune and inflammatory diseases," said Dr. Afeyan, Chairman, Evelo Biosciences and CEO of Flagship Ventures. "As the microbiome field begins to turn its attention to diseases beyond gut infections, we see the combination of these two first-mover companies as an important strategic development aimed at creating sufficient critical mass to lead the field."

"I look forward to accelerating and broadening Evelo’s development through this strategic combination," said Dr. Gill "With our expanded team working together on the immuno-microbiome, we expect to more rapidly advance multiple new product candidates into the clinic, build partnerships and deliver important treatments to patients who need them."

The two partners have been working together successfully under a research collaboration since 2012 and Bayer has already licensed two programs for multiple series of small molecules from X-Chem that address complex target structures such as protein:protein interactions. The new multi-year collaboration agreement will significantly expand the scope and duration of the partnership.

"Bayer and X-Chem have built a strong relationship delivering outcomes that have exceeded expectations. Complementing our in-house expertise with technologies and know-how of excellent partners is an integral part of our innovation strategy at Bayer," said Professor Andreas Busch, member of the Executive Committee of Bayer AG’s Pharmaceuticals Division and Head of Drug Discovery. "We have identified the DEX platform as a highly valuable extension for our drug discovery efforts. We are looking forward to working with X-Chem on some of our highest-priority targets, for which X-Chem’s platform is ideally suited."

Under the terms of this new agreement, X-Chem will receive an up-front payment, research and development funding, as well as potential pre-clinical, clinical and regulatory milestone payments, up to a total of $528 million. Bayer has an exclusive option to license any programs generated in the course of the collaboration. X-Chem will also receive royalties and sales milestones for each successfully commercialized drug that results from a licensed collaboration program.

"X-Chem is making significant inroads toward the discovery of small molecule drug candidates using its ultra-large screening library. With multiple successes across our partnerships, the DEX platform has been broadly validated to deliver novel chemical entities against a wide array of targets, including difficult targets," said Rick Wagner, Ph.D., Chief Executive Officer of X-Chem. "We are fortunate to have Bayer as a major strategic partner, and we are looking forward to expanding this strong and successful relationship. X-Chem is excited to continue working with Bayer on a wider array of diseases and conditions with significant unmet medical needs."

About the DNA-Encoded X-Chem (DEX) Library and Platform
Due to the size and diversity of the DEXTM library, X-Chem can discover multiple series of novel, potent and selective lead compounds at an unprecedented rate of success against a wide range of targets, including some that previously failed using conventional screening methods. A number of proprietary innovations in library design, screening methodology and bioinformatics underlie the exceptional performance of the DEXTM platform. In particular, X-Chem’s approach to library construction allows for additional chemical reactions to become useable in DNA-encoded library synthesis. Together, these developments result in a much greater repertoire of diversity for small molecules, which cover a range of categories including fragment molecules, small molecular weight heterocyclic compounds, and macrocyclic structures. This diverse library, combined with a heightened ability to detect active molecules, has yielded a robust process that has been highly successful against targets categorized as difficult or intractable.

About DNA-Encoding
The X-Chem drug discovery engine is based on a library, currently in excess of 120 billion compounds and growing, generated by iterative combinatorial synthesis of small molecules tethered to DNA tags that record the synthetic history of the small molecule. Every small molecule in the library has a unique DNA barcode attached it. The library is screened as a mixture using affinity-based binding to a target of interest. Certain rare molecules in the library that bind to the target can be "fished out," while the rest of the molecules are washed away. DNA sequencing methods are then used to detect molecules that are enriched when bound to the target. The diverse nature of the library produces multiple families or clusters of related molecules that bind to the target, forming a basis for emergent structure-activity relationships. Structure-activity relationships are typically used by medicinal chemists to guide iterative chemical maturation of a molecule into a drug. Based on the synthetic history encoded in the DNA sequence information, molecules are then made without the DNA tag attached, and tested for activity in conventional assays.
