(NGM Bio) (Nasdaq: NGM), a biotechnology company focused on discovering and developing transformative therapeutics for patients, today provided recent business highlights and reported financial results for the fourth quarter and full year ended December 31, 2023. “In 2023, we made significant progress in patient enrollment in trials of our solid tumor drug candidates. Most notably, we are encouraged by the signals of activity observed in our NGM707 Phase 1b trial, particularly among MSS CRC patients whose lesions are typically unresponsive to immuno-checkpoint therapies. We also made progress in our discussions with the FDA regarding the design of a potential registrational Phase 2 study of aldafermin in PSC using a primary endpoint composed of surrogate biomarkers of PSC progression and obtained orphan drug designation from the agency for aldafermin for the treatment of PSC,” said David J. Woodhouse, Ph.D., Chief Executive Officer at NGM Bio. “In 2024, we are focused on completing patient enrollment for NGM707 with a potential interim Phase 1b trial readout in the middle of the year, initiating a potential Phase 2 proof-of-concept trial of NGM120 in HG by the end of 2024, and, provided we have the financial resources and agreement on trial design, initiating a registrational Phase 2 trial of aldafermin in PSC patients. Our priority remains to seek licensing and other business development partners across all our wholly-owned product candidates and to allocate our resources to the programs that we believe have the greatest potential both in the near- and long-term.” Key Fourth Quarter and Recent Highlights Solid Tumor Oncology Disclosed in January 2024 encouraging findings in a Phase 1 Part 1b cohort of the ongoing Phase 1/2 trial evaluating NGM707 in combination with pembrolizumab for the treatment of patients with advanced or metastatic solid tumors, including MSS CRC patients. 46 patients were enrolled as of the November 6, 2023 data-cutoff and, of the 37 response-evaluable patients (those completing at least one on-treatment scan), there were four confirmed partial responses across multiple indications, including one pathological complete response, and 12 patients with stable disease (11% overall response rate and 43% disease control rate). The combination of NGM707 and pembrolizumab was generally well-tolerated at all four doses (200, 600, 1200, 1800 mg) of NGM707. The maximum tolerated dose was not reached. NGM Bio expects to complete enrollment in the Phase 1 Part 1b cohort in the second quarter of 2024 and anticipates providing an update in mid-2024 on the fully enrolled cohort and subsequent next steps, including, provided sufficient financial resources, the potential for additional cohorts, which NGM Bio expects will include MSS CRC patients.Completed enrollment in the Phase 1 Part 1b cohorts of the Phase 1/1b trials evaluating NGM831, an ILT3 antagonist antibody product candidate, and NGM438, a LAIR1 antagonist antibody product candidate, in combination with pembrolizumab in patients with advanced solid tumors. NGM831 and NGM438, alone and in combination with pembrolizumab, have been generally well-tolerated and there have been no dose limiting toxicities noted to date.Initiated an ongoing Phase 1, Part 1c dose finding cohort evaluating the triplet combination of NGM831, NGM438 and pembrolizumab. This cohort is anticipated to complete enrollment in the first half of 2024. Hyperemesis Gravidarum Announced in January 2024 potential development of NGM120 for the treatment of HG. NGM120, a GFRAL antagonist antibody, is designed to block GDF15 signaling, the central cause of HG and, thereby, may potentially have therapeutic benefit for treating pregnant women suffering from HG. HG is a rare, serious condition that affects approximately 100,000 – 150,000 women in the United States each year during pregnancy and is characterized by intractable nausea and vomiting, which then results in dehydration, weight loss and malnutrition. HG has a significant physical and psychosocial impact on patients and leads to overall higher rates of fetal loss, preeclampsia, preterm birth, low birth weight and fetal malnutrition. HG is the second leading cause of hospitalization in pregnancy (second to preterm labor) and typically recurs in subsequent pregnancies. There are currently no FDA-approved therapies for this condition. Research1 has shown that GDF15 levels increase steadily in early pregnancy and, on average, are higher in women who experience nausea and vomiting in pregnancy and HG. The research also indicated that women with GDF15 genetic variants associated with lower levels of GDF15 in a non-pregnant state are predisposed to HG.NGM Bio’s goal is to initiate a Phase 2 proof-of-concept study of NGM120 for the treatment of HG by the end of 2024. NGM Bio is in the process of producing a toxicology package to submit to regulatory authorities in Australia or the United Kingdom that we hope will support initiation of the trial. Aldafermin Presented positive Phase 2b results from the ALPINE 4 trial of aldafermin in compensated cirrhosis (F4) due to NASH at AASLD The Liver Meeting in November 2023.In January 2024, announced U.S. Food and Drug Administration (FDA) granted orphan drug designation to aldafermin, an engineered FGF19 analog, for the treatment of PSC.NGM Bio plans to further develop aldafermin for the treatment of PSC, a rare liver disease that irreparably damages the bile ducts, leading to bile acid dysregulation, which, ultimately, results in serious liver damage. There are currently no FDA-approved therapies for PSC. NGM Bio is continuing discussions with the FDA regarding the design of a potential registrational trial of aldafermin in PSC, including on the proposed utilization of a primary endpoint composed of surrogate biomarkers with the goal of obtaining accelerated approval from the FDA. NGM Bio plans to continue working towards the goal of initiating a potential registrational trial contingent upon further discussion with the FDA on trial design and obtaining the additional capital necessary to conduct the study. Corporate On February 26, 2024, NGM Bio announced that it had entered into the Agreement and Plan of Merger (Merger Agreement) with Atlas Neon Parent, Inc. (Parent) and Atlas Neon Merger Sub, Inc., a wholly-owned subsidiary of Parent (Merger Sub). The Merger Agreement provides for, among other things, (i) the acquisition of NGM Bio by Parent through a cash tender offer (the Offer) by Merger Sub for each issued and outstanding share of NGM Bio’s common stock (other than certain rollover shares) for $1.55 per share (the Offer Price), and (ii) the merger of Merger Sub with and into NGM Bio (the Merger), with NGM Bio surviving the Merger as a privately held company. Subject to the terms of the Merger Agreement, the Offer Price will be paid subject to any applicable tax withholding and without interest. Pursuant to the Merger Agreement, on March 8, 2024, Parent commenced the Offer. Additional details can be found in NGM Bio’s recent filings with the United States Securities and Exchange Commission (SEC).NGM Bio anticipates that the Offer and the Merger contemplated under the Merger Agreement will be consummated in the second quarter of 2024. However, closing of the Merger is subject to customary closing conditions, and there can be no assurance that the Offer and the Merger contemplated by the Merger Agreement will be completed. If the Merger is effected, NGM Bio’s common stock will be delisted from The Nasdaq Stock Market LLC and NGM Bio will be privately held.
