SpringWorks Therapeutics Inc. said Monday it has entered into a clinical collaboration and supply agreement with Janssen Biotech Inc. to evaluate a myeloma treatment.

The companies will research SpringWorks' investigational gamma secretase inhibitor nirogacestat in combination with Janssen's bispecific antibody targeting B-cell maturation antigen and CD3, teclistamab, in patients with relapsed or refractory multiple myeloma.

The biopharmaceutical company said that in preclinical models, nirogacestat has been shown to increase the cell surface density of B-cell maturation antigen and reduce levels of soluble BCMA, which may enhance the activity of BCMA-targeted therapies, including CD3 bispecific antibodies.

Janssen will sponsor and conduct the Phase 1 study to evaluate the safety, tolerability and preliminary efficacy of the combination, and will assume all costs associated with the study, other than expenses related to the manufacturing of nirogacestat. SpringWorks Therapeutics will also form a joint oversight committee with Janssen. The study is anticipated to begin by early 2021.

In addition to its ongoing clinical collaborations with BCMA-directed therapies, SpringWorks said it is also currently conducting a global Phase 3, double-blind, randomized, placebo-controlled clinical trial to evaluate nirogacestat in adults with progressing desmoid tumors.
