An Open Label, Randomized, Multicenter, Phase Ib/II Trial Evaluating the Safety, Tolerability, Pharmacokinetics, and Efficacy of Mosunetuzumab (BTCT4465A) in Combination with Polatuzumab Vedotin in patients with B-Cell Non-Hodgkin Lymphoma(GO40516)(PSCI18-058)
This is a drug study that will compare drug mosunetuzumab with drug polatuzumab vedotin in patients with non-Hodgkin lymphoma (NHL).
This study has three parts: 1. Screening (to see if you are eligible for the study) 2. Treatment 3. Follow-up (to check on you after treatment is finished) If you are enrolled in the FL or DLBCL cohort during the single-arm expansion phase, you will receive mosunetuzumab for 8-17 cycles and polatuzumab vedotin for 6 cycles, with each cycle lasting 21 days. In addition to the single-arm expansion phase, the study may open another expansion phase of the study for the DLBCL cohort. If you are enrolled in the additional DLBCL expansion phase, you will be randomly assigned to one of three possible arms. Neither you nor your study doctor may choose the arm you will be in. - Mosunetuzumab in combination with polatuzumab vedotin - Mosunetuzumab alone - Bendamustine plus rituximab in combination with polatuzumab vedotin After your last dose, your study doctor will follow up with you about every 3 months for approximately 2 years or longer (as long as you agree to it). Your total time in the study (Phase II expansion portion) will depend on how your DLBCL, FL, or MCL responds to treatment. This could range from 1 day to more than 2 1/2 years.
