A Clinical Study to Evaluate the Effects of RO7875913 in Healthy Participants and of RO7875913 With Cevostamab in Participants With Relapsed/Refractory Multiple Myeloma
En fase I-dosisstigningsundersøgelse til vurdering af sikkerhed, farmakokinetik og farmakodynamik for RO7875913 hos raske frivillige
Part A: The purpose of Part A of this study is to evaluate the safety, pharmacokinetics, and pharmacodynamics of RO7875913 in healthy participants.
Part B: The purpose of Part B of this study is to evaluate the safety, pharmacokinetics, pharmacodynamics, and preliminary clinical activity of RO7875913 administered in combination with the T cell-engaging bispecific antibody (TCB) cevostamab in participants with relapsed or refractory (R/R) multiple myeloma (MM).
