NCT05139225: Phase 1: A Study of TTI-621 and TTI-622 in Combination With Daratumumab Hyaluronidase-fihj in People With Multiple Myeloma

A Study of TTI-621 and TTI-622 in Combination With Daratumumab Hyaluronidase-fihj in People With Multiple Myeloma

This study will test the safety of TTI-621 or TTI-622 in combination with daratumumab hyaluronidase-fihj in people with relapsed/refractory multiple myeloma. The researchers look for the highest dose of TTI-621 and TTI-622 that causes few or mild side effects in participants when given in combination with daratumumab hyaluronidase-fihj. Once the researchers find the highest safe dose of each study drug, they will further test the combinations (TTI-621 + daratumumab hyaluronidase-fihj and TTI-622 + daratumumab hyaluronidase-fihj) in new participants to find out if the combinations are effective in treating relapsed/refractory multiple myeloma. Researchers think that combining TTI-621 or TTI-622 with daratumumab hyaluronidase-fihj, a standard treatment for multiple myeloma, may be an effective treatment approach.
