Study Summary

This trial is testing mosunetuzumab as a treatment for aggressive B cell lymphomas. Mosunetuzumab is an antibody that targets T cells and cancerous B cells. The goal is to use mosunetuzumab to direct T cells to kill cancerous B cells.

Who is the study for?
Adults with aggressive B cell lymphomas who are planning to undergo autologous stem cell transplant. They must have adequate organ function, no recent major infections or vaccinations, and not be pregnant. Men and women must agree to use effective contraception during the study and for 3 months after the last dose of mosunetuzumab.Check my eligibility
What is being tested?
The trial is testing mosunetuzumab as a consolidation therapy post-autologous stem cell transplant in patients with relapsed or refractory aggressive B cell lymphomas. Mosunetuzumab is an engineered antibody designed to direct T cells to kill cancerous B cells.See study design
What are the potential side effects?
Potential side effects include reactions related to immune system activation such as inflammation in various organs, infusion-related reactions, increased risk of infection, and possibly others that are currently unknown due to the investigational nature of mosunetuzumab.

Experimental Treatment
Group I: Consolidation MosunetuzumabExperimental Treatment1 Intervention
Mosunetuzumab is a CD3xCD20 bispecific antibody administered intravenously in the consolidation setting after autologous stem cell transplant (autoSCT). Mosunetuzumab will be given in a step-up dosing schedule beginning on Day 49 after autoSCT on C1D1, C1D8, C1D15, and then Day 1 of all cycles thereafter. Patients will undergo PET-CT restaging around Day 100 post-autoSCT (approximately Cycle 3) and patients in complete response will continue mosunetuzumab for up to 17 cycles in the absence of disease progression or unacceptable toxicity. Patients not in complete response will discontinue treatment and enter follow-up. All cycles are planned to be 21 days.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What positive effects are researchers hoping to observe from this clinical trial?

"Genentech, Inc., the sponsor of this trial, has defined a primary outcome measure to be evaluated over an interval estimated at one year and thirty days. This metric is the frequency and severity of treatment-emergent adverse events (TEAEs). Additionally, secondary objectives include progression free survival (PFS), percentage of patients requiring any doses for cytokine release syndrome management with tocilizumab, as well as number of tocilizumab doses per patient for CRS management."

Answered by AI

Are there still options for patient enrollment in this experiment?

"Clinicaltrials.gov reports that this medical trial is not currently enrolling volunteers, despite being initially posted on the 31st of December 2022 and having its information last updated on November 8th 2022. Nonetheless, there are 1,832 other trials actively recruiting patients at present."

Answered by AI

Has Mosunetuzumab gained regulatory approval from the Food and Drug Administration?

"The safety of Mosunetuzumab has been assigned a rating of 1, as this is an early phase medical trial with only preliminary evidence to support the drug's efficacy and security."
