DepYmed and Monash Biomedicine Discovery Institute to Study the Role of a New Generation of PTP1B Inhibitors against a Novel Intracellular Checkpoint in Cancer

Cancer Discovery1 that PTP1B acts as an Intracellular Checkpoint and PTP1B Inhibition Represses Tumor Growth
NEW YORK (March 10, 2022) - DepYmed, Inc. (“DepYmed” or the “Company”) and the Monash Biomedicine Discovery Institute (“Monash BDI”) at Monash University in Melbourne, Australia announce today that they have entered into a sponsored research agreement (SRA) to explore the potential of the Company’s drug development candidates to treat cancer by targeting a newly discovered intracellular immune checkpoint.
The new agreement builds on recent results from a collaborative study led by Monash BDI that identified a new immune checkpoint that could provide a new therapeutic strategy for treating certain cancers by inhibiting the protein tyrosine phosphatase PTP1B in T cells, mobilizing the body’s immune system to repress tumour growth. These findings were the subject of a March 8, 2022, Monash BDI press release announcing their publication in a leading peer-reviewed medical journal, Cancer Discovery.2
The study’s findings revealed PTP1B is a novel intracellular checkpoint and that PTP1B inhibition represses tumor growth and enhances the response of surface checkpoint inhibitors when used in combination. It also demonstrated that PTP1B inhibition increased the activity of CAR-T cells, an innovative form of immunotherapy that has to date only been useful in blood cancers, in a solid tumor model.
"This partnership is an important part of our development strategy, as we begin to explore the incredible potential of PTP1B inhibition in a research and commercial environment that is tuned into checkpoint inhibition. We believe this represents an untapped approach to treating cancers and we anticipate further exploration,” commented Andreas Grill, DepYmed’s CEO. “The results from the publication are extremely encouraging and we look forward to the results of this collaboration with Monash BDI.”
T cells are a critical part of the body’s immune system that help prevent the growth of cancer cells. One of the important ways that cancers develop occurs when cancer cells acquire the ability to evade recognition by T cells. This new study found that PTP1B is increased in T cells in cancer, limiting their ability to attack tumour cells. In recent years, new cancer therapies that target immune checkpoints on the surface of T cells has revolutionized the treatment of many cancers. However, many patients do not respond or develop resistance to these checkpoint inhibitors, creating a significant need for new treatments that can be used in these patients or in combination with surface checkpoint inhibitors.
DepYmed is developing a new class of drug candidates that act by inhibiting PTP1B. The research sponsored under the new agreement aims to confirm that its drug candidates also target this intracellular checkpoint mechanism and inhibit tumor growth in preclinical cancer models. Confirmation of this novel mechanism would underscore the therapeutic potential of DepYmed’s drug candidates in cancer. The Company is the first to develop orally bioavailable PTP1B inhibitors and hopes to initiate Phase 1 clinical trials for these candidates later this year. Its drug development programs are based on the research of Nicholas Tonks, Caryl Boies Professor of Cancer Research at Cold Spring Harbor Laboratory, and the original discoverer of the PTP1B pathway. Professor Tonks was also a collaborator in the Cancer Discovery publication.
The sponsored research under the SRA will be conducted at the Monash BDI laboratory of Professor Tony Tiganis, the paper’s senior author.
