Mediar Therapeutics Announces Clinical Candidates for Lead Fibrosis Programs, Strategic Collaborations and Key Leadership Addition

CAMBRIDGE, Mass., October 25, 2023 – Mediar Therapeutics Inc., a biotechnology company advancing a portfolio of first-in-class therapies that halt fibrosis progression, today announced several milestones that support clinical advancement of its portfolio of novel antibodies: the nomination of two clinical candidates, key strategic collaborations with Pfizer Ignite and WuXi Biologics, and the appointment of Jeffrey D. Bornstein, M.D., as Chief Medical Officer.

Mediar’s first candidate, MTX-463, is a first-in-class monoclonal antibody designed to neutralize the WISP-1 signaling that is elevated in and contributes to fibrosis progression. Its second candidate, MTX-474, is a first-in-class monoclonal antibody designed to neutralize the EphrinB2 signaling that causes fibrosis advancement and may play a role in defining the fibrotic niche. Both candidates offer therapeutic potential across multiple indications, including fibrosing diseases of the lung and liver, and are supported by a compelling suite of preclinical in vivo and ex vivo data demonstrating specific anti-fibrotic effects and selective neutralization of their respective targets. Mediar plans to advance both MTX-463 and MTX-474 into Phase 1 clinical development in 2024.
