NGM

NGM Biopharmaceuticals, Inc. (NGM Bio) (Nasdaq: NGM), a biotechnology company focused on discovering and developing transformative therapeutics for patients, today announced it will host the third of four virtual R&D events on Tuesday, May 31, 2022, from 12:00 pm – 1:15 pm ET. This four-part series of virtual webcasts, titled the “Explorer Series”, will highlight the company’s work as explorers on the frontier of life-changing science.

The third event will focus on NGM Bio’s lead myeloid checkpoint inhibition and reprogramming program, NGM707, a dual ILT2/ILT4 antagonist antibody product candidate. ILT2 and ILT4 are members of the LILR family of receptors, which may play a central role in establishing an immune-suppressive state in the tumor microenvironment. NGM707 is engineered to target both ILT2 and ILT4 with the goal of releasing myeloid checkpoints and reprogramming myeloid cells to enhance anti-tumor immunity. The program will feature presentations from multiple members of NGM Bio’s research and development team and from Dr. Marco Colonna, M.D., Professor of Pathology & Immunology at the Washington University School of Medicine in St. Louis.

The fourth and final session in the series will focus on NGM621, a monoclonal antibody product candidate engineered to potently inhibit complement C3, for the treatment of patients with geographic atrophy.

A live webcast of the presentation will be available under the Investors and Media section of NGM Bio’s website at https://ir.ngmbio.com/events-presentations. A replay of the webcast will be archived on NGM Bio’s site for one year following the event.
