Multiple myeloma is a malignant plasma cell disorder characterized by osteolytic lesions, increased susceptibility to infections, hypercalcemia, and renal failure.
Overall rationale of study is that daratumumab in combination with JNJ-64407564 [anti-GPRC5DxCD3] or JNJ-64007957 [anti-BCMAxCD3] may lead to enhanced clinical responses in treatment of relapsed or refractory multiple myeloma through multiple mechanisms of action. Daratumumab is human immunoglobulin G1 kappa monoclonal antibody (IgG1k) that binds with high affinity to a unique epitope on cluster of differentiation 38 (CD38) in a variety of hematological malignancies including multiple myeloma. JNJ-64407564 (anti-GPRC5DxCD3) and JNJ-64007957 (anti-BCMAxCD3) are bispecific T cell redirection antibodies. JNJ-64407564 (anti-GPRC5DxCD3) binds to cluster of differentiation 3 (CD3) receptor complex on T cells and to G protein-coupled receptor family C group 5-member D (GPRC5D), a 7‑transmembrane receptor protein on plasma cells and JNJ-64007957 (anti-BCMAxCD3) binds to human and cynomolgus-CD3 and B cell maturation antigen (BCMA).
Purpose of study is to evaluate safety of daratumumab in combination with bispecific T cell redirecting antibodies, and to evaluate antitumor activity of each combination. Study consists of a screening period, treatment period (Part 1: dose escalation and Part 2: dose expansion) and a post treatment follow-up period (after end of treatment and up to 16 weeks after last dose.
End of study is defined as last study assessment for last participant in study. Total duration of study is approximately 2.4 years. Efficacy, safety, pharmacokinetics (PK), immunogenicity, and biomarkers will be assessed at specified time points. Participants safety will be monitored throughout study by Study Evaluation Team (SET). SET consists of members of sponsor's study team and participating investigators.
