NGM Bio Announces Clinical Trial Collaboration with Merck Related to Ongoing Phase 1/2 Trial of NGM707, an ILT2/ILT4 Dual Antagonist Antibody, in Combination with Merck’s KEYTRUDA® (pembrolizumab)

Montag, 06. Dezember 2021 14:00
  • NGM entered into a clinical trial collaboration and supply agreement with Merck to evaluate the potential of NGM707 in combination with KEYTRUDA for the treatment of patients with advanced or metastatic solid tumors
  • NGM707 is part of NGM’s wholly-owned portfolio of immuno-oncology programs focused on releasing myeloid checkpoints to reprogram myeloid cells to reverse immune suppression
  • ILT2 and ILT4, upregulated in certain tumor types, are believed to serve as myeloid checkpoints, helping tumors evade immune detection
  • NGM707 is designed to reprogram ILT4-expressing myeloid cells and stimulate the activity of ILT2 expressing myeloid and lymphoid cells to enhance anti-tumor immunity
  • NGM’s additional myeloid checkpoint inhibitor candidates include NGM831 and NGM438, ILT3 and LAIR1 antagonist antibodies

SOUTH SAN FRANCISCO, Calif., Dec. 06, 2021 (GLOBE NEWSWIRE) -- NGM Biopharmaceuticals, Inc. (NGM) (Nasdaq: NGM), a biotechnology company focused on discovering and developing transformative therapeutics for patients, today announced a clinical trial collaboration and supply agreement with Merck (known as MSD outside of the United States and Canada) to evaluate NGM707, NGM’s wholly-owned novel ILT2/ILT4 dual antagonist antibody, in combination with Merck’s anti-PD-1 therapy, KEYTRUDA. NGM is currently enrolling patients in the Phase 1/2 trial, initiated in June 2021, to evaluate the potential of NGM707 as a monotherapy and in combination with KEYTRUDA in adult patients with advanced or metastatic solid tumors with elevated expression of ILT2 and ILT4.

“ILT2 and ILT4 are among a group of myeloid immune checkpoint receptors that are upregulated in patients who do not respond to T-cell checkpoint therapy, suggesting that they are potential resistance mechanisms that generate an immunosuppressive state in the tumor microenvironment. We’re excited by the unique profile of NGM707 in the myeloid checkpoint inhibition space. Our preclinical studies suggest that NGM707’s dual blockade of ILT2 and ILT4 may be more effective than blockade of either receptor alone in reversing myeloid based immune suppression, which is known to limit anti-tumor immunity,” said Hsiao D. Lieu, M.D., Chief Medical Officer at NGM Bio.

Dr. Lieu continued, “We’re pleased to enter into this agreement with Merck for our ongoing Phase 1/2 trial of NGM707. In preclinical models, we have demonstrated that NGM707 in combination with KEYTRUDA acts additively to increase T cell activation and cytokine secretion. We look forward to evaluating how these mechanisms of action translate in the clinic to potentially enable broader and deeper anti-tumor immune responses, bringing the promise of immunotherapy to more cancer patients.”

ILT2 and ILT4, inhibitory receptors with enriched expression on myeloid cells in the tumor microenvironment, are myeloid checkpoints that may enable certain tumors to evade immune detection, thereby suppressing patients’ anti-tumor response.  NGM707 is being developed with the goal of improving patient immune response to tumors by inhibiting both ILT2 and ILT4. By inhibiting both ILT2 and ILT4, NGM707 may be able to overcome the potential redundant role the two receptors play when co-expressed in myeloid cells and reprogram those cells to enhance T cell activity and proliferation. In addition, ILT2 blockade may drive further benefit through reducing suppression in certain lymphoid cells capable of directly attacking tumor cells.

About the NGM707 Phase 1/2 Trial Design

The Phase 1 portion (n≅60) of the trial includes a monotherapy dose escalation arm (Part 1a) and a dose-finding arm in combination with KEYTRUDA® (pembrolizumab) (Part 1b). The Phase 2 portion (n≅120) of the trial will employ a basket design that will include expansion cohorts of patients treated with NGM707 monotherapy (Part 2a) or NGM707 in combination with KEYTRUDA (Part 2b) in a variety of selected solid tumor types.
