ST-067 is an engineered variant of the human cytokine interleukin-18 that may help the immune system kill cancer cells. Teclistamab is a bispecific antibody that can bind to two different antigens at the same time. Teclistamab binds to B-cell maturation antigen (BCMA), a protein found on some B-cells and myeloma cells, and CD3 on T-cells (a type of white blood cell) and may interfere with the ability of cancer cells to grow and spread. Giving ST-067 in combination with teclistamab may be safe, tolerable and/or effective in treating patients with relapsed or refractory multiple myeloma.', 'detailedDescription': 'OUTLINE: This is a dose-escalation study of ST-067 in combination with teclistamab followed by a dose-expansion study.\n\nPatients receive ST-067 subcutaneously (SC) on days 1, 8, 15 and 22 of cycle 1, on days 8, 15 and 22 of cycle 2, then on days 1 and 15 of subsequent cycles.
