SpringWorks Therapeutics Announces Clinical Collaboration with AbbVie to Evaluate Nirogacestat in Combination with ABBV-383 in Patients with Relapsed or Refractory Multiple Myeloma

– Seventh Clinical Collaboration Represents Continued Execution on Strategy to Advance Nirogacestat in Combination with BCMA Therapies –
STAMFORD, Conn., Dec. 10, 2021 (GLOBE NEWSWIRE) -- SpringWorks Therapeutics, Inc. (Nasdaq: SWTX), a clinical-stage biopharmaceutical company focused on developing life-changing medicines for patients with severe rare diseases and cancer, today announced that the company has entered into a clinical trial collaboration agreement with AbbVie, Inc. to evaluate nirogacestat, SpringWorks’ investigational gamma secretase inhibitor, in combination with ABBV-383, AbbVie’s investigational CD3 bispecific antibody directed against B-cell maturation agent (BCMA), in patients with relapsed or refractory multiple myeloma.
Gamma secretase inhibition helps prevent the cleavage and shedding of BCMA from the surface of myeloma cells. In preclinical models, nirogacestat has been shown to increase levels of membrane-bound BCMA and reduce levels of soluble BCMA, thereby helping to enhance the activity of BCMA-targeted therapies, including CD3 bispecific antibodies.1,2
“We continue to progress our strategy to evaluate nirogacestat in combination with BCMA therapies for patients with multiple myeloma and are delighted to enter into our seventh BCMA clinical collaboration. We look forward to working with AbbVie to study nirogacestat in combination with ABBV-383,” said Saqib Islam, Chief Executive Officer of SpringWorks. “Together with our industry-leading collaborators, our goal remains to meaningfully improve clinical outcomes for patients with multiple myeloma.”
Under the terms of the agreement, AbbVie will sponsor and conduct the Phase 1b study to evaluate the safety, tolerability, and preliminary efficacy of the combination in patients with relapsed or refractory multiple myeloma, and will assume all costs associated with the study, other than expenses related to the manufacturing of nirogacestat and certain expenses related to intellectual property rights. AbbVie and SpringWorks will also form a joint steering committee to manage the clinical study, which is expected to commence in the first half of 2022.
Nirogacestat is an investigational, oral, selective, small molecule gamma secretase inhibitor in Phase 3 clinical development for desmoid tumors, which are rare and often debilitating and disfiguring soft-tissue tumors. Gamma secretase cleaves multiple transmembrane protein complexes, including Notch, which is believed to play a role in activating pathways that contribute to desmoid tumor growth.
In addition, gamma secretase has been shown to directly cleave membrane-bound BCMA, resulting in the release of the BCMA extracellular domain, or ECD, from the cell surface. By inhibiting gamma secretase, membrane-bound BCMA can be preserved, increasing target density while reducing levels of soluble BCMA ECD, which may serve as decoy receptors for BCMA-directed therapies. Nirogacestat’s ability to enhance the activity of BCMA-directed therapies has been observed in preclinical models of multiple myeloma.1,2 SpringWorks is evaluating nirogacestat as a BCMA potentiator and has seven collaborations with industry-leading BCMA developers to evaluate nirogacestat in combinations across modalities, including with an antibody-drug conjugate, two CAR T cell therapies, three bispecific antibodies and a monoclonal antibody. SpringWorks has also formed research collaborations with Fred Hutchinson Cancer Research Center and Dana-Farber Cancer Institute to further characterize the ability of nirogacestat to modulate BCMA and potentiate BCMA-directed therapies using a variety of preclinical multiple myeloma models.
Nirogacestat has received Orphan Drug Designation from the U.S. Food and Drug Administration (FDA) for the treatment of desmoid tumors and from the European Commission for the treatment of soft tissue sarcoma. The FDA also granted Fast Track and Breakthrough Therapy Designations for the treatment of adult patients with progressive, unresectable, recurrent or refractory desmoid tumors or deep fibromatosis.
