NGM Bio to Host the Second of Four Virtual R&D Events on April 27, 2022

NGM831 and NGM438, NGM Bio’s myeloid reprogramming antibody product candidates targeting stromal checkpoints, will be showcased in the second of a four-part series titled the “Explorer Series”SOUTH SAN FRANCISCO, Calif., April 20, 2022 (GLOBE NEWSWIRE) — 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 second of four virtual R&D events on Wednesday, April 27, 2022, from 11:00 am – 12:30 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 second event will focus on NGM Bio’s myeloid reprogramming programs targeting stromal checkpoints: NGM831, an ILT3 antagonist antibody product candidate, and NGM438, a LAIR1 antagonist antibody product candidate. ILT3 and LAIR1 are members of the LILR family of receptors, which may play a central role in establishing an immune-suppressive state in the tumor microenvironment. NGM831 and NGM438 are engineered to target ILT3 and LAIR1, respectively, with the goal of releasing myeloid checkpoints and reprogramming myeloid cells to enhance anti-tumor immunity. The program will feature presentations from David Woodhouse, Ph.D., NGM Bio’s Chief Executive Officer, Dr. Don Gibbons, M.D., Ph.D. at the MD Anderson Cancer Center where he is the Director of the Thoracic – Head and Neck Medical Oncology Translational Genetic Models Laboratory and Co-Leader of the Lung Cancer Moon Shot Program and multiple members of NGM Bio’s research and development team. Future sessions will focus on NGM707, a dual ILT2/ILT4 antagonist antibody product candidate, and NGM621, an anti-complement C3 antibody product candidate. Both sessions will feature members from NGM Bio’s management and scientific team as well as leading industry physicians and scientists. 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.
