Advisor, ADC Discovery
Jonathan Davis received his Ph.D. from University of California, San Francisco, where he studied protein structure and function using NMR. After a post-doc at Harvard Medical School exploring RNA selection and structure in the labs of Jack Szostak and Gerhard Wagner, he went to work at EMD Serono, where his work involved improving antibody-based therapeutics, inventing a platform technology for generating heterodimeric Fcs as a basis for multifunctional molecules, and developing a novel scaffold based on an artificially-designed protein from David Baker’s lab. In 2008 he took a job at Bristol-Myers Squibb in Waltham/Cambridge MA, working on antibody discovery and platform development in a wide range of therapeutic areas, with a particular focus on multispecific therapeutics. He moved to Madison, WI in 2019 to take on the role of VP of Innovation and Strategy at Invenra, a biotech focused on bispecific antibodies, and where he is currently head of the Scientific Advisory Board. In early 2024 he left the corporate world to found Creative Antibodies, a consulting firm that helps guide companies to successful antibody discovery and development projects, from mAbs to multispecifics, ADCs, and other formats. Outside of science, Jonathan is a conservatory trained cellist, plays numerous other instruments, and founded the UCSF Orchestra (now Symphony Parnassus) in San Francisco, where he was Music Director for six years.

L‑DOS47 is a first‑in‑class, clinical-stage antibody‑enzyme conjugate designed to deliver a game-changing assist to anti-cancer immunity and today’s leading cancer immunotherapies for the treatment of prevalent, hard-to-treat solid tumors. The compound precisely targets CEACAM6, a cell-surface protein overexpressed in non‑small cell lung cancer (NSCLC) and other aggressive tumors, where it delivers an enzymatic payload that raises the extracellular pH of the acidic tumor microenvironment (TME). By neutralizing tumor acidity, L-DOS47 restores immune cell infiltration and activity, helps turn immunologically “cold” tumors “hot”, and enhances the therapeutic reach of immune checkpoint inhibitors. With patented composition-of-matter coverage through 2036 and demonstrated synergy with PD-1 inhibitor, pembrolizumab, L-DOS47 is poised to significantly increase the efficacy of immune checkpoint blockade and unlock broader and more durable responses in NSCLC and other aggressive solid tumors.

LEUMUNA™ is an oral immune checkpoint modulator designed to activate the donor immune system to recognize and fight relapsing leukemia in patients who have undergone allogeneic stem cell transplantation (allo-SCT). Although a life-saving procedure, up to 30% of patients who undergo allo-SCT see their cancer return, facing a median survival of just four months. LEUMUNA aims to offer these patients a new lease on life, by activating an immune cascade and inciting graft-versus-leukemia (GvL) effect, potentially offering long-term remission. Backed by strong preclinical data and a promising safety record from trials with its precursor compound, ulodesine, LEUMUNA offers a patient‑friendly, oral approach to a difficult-to-treat condition, with patent protection through 2041 and an Orphan Drug Designation granted by the US FDA.

GEMCEDA is a first-in-class oral prodrug of gemcitabine that opens up the possibility for convenient at-home administration, metronomic dosing and seamless integration into combination regimens with immune checkpoint inhibitors. To date, gemcitabine is only administered intravenously because oral forms have shown poor bioavailability of about 10%. GEMCEDA was developed as a prodrug to enable new uses of gemcitabine by combining it with cedazuridine, an enzyme inhibitor that helps boost its bioavailability to 90%. This remarkable innovation allows for greater flexibility in dosing schedules, fewer clinic visits, and a better quality of life, while achieving bioavailability on par with intravenous gemcitabine. Supported by a well‑established safety profile, scalable manufacturing, and patent coverage to 2043, GEMCEDA reimagines how chemotherapy can fit into patients’ lives.
