What side effects are associated with this type of intervention?

Common treatments for Non-Hodgkin's Lymphoma, particularly those involving monoclonal antibodies like rituximab, ofatumumab, and obinutuzumab, can cause infusion reactions such as fever, chills, rash, and hypotension, especially during the first cycle. Chemotherapy regimens, such as those involving bendamustine, often lead to myelosuppression, resulting in neutropenia, anemia, and thrombocytopenia, along with nausea, vomiting, fatigue, and increased infection risk. Combining these treatments can enhance efficacy but also compound the side effects.

What prior FDA approvals exist?

The FDA has approved several treatments for Non-Hodgkin's Lymphoma, including monoclonal antibodies and bispecific antibodies. Rituximab, a monoclonal antibody targeting CD20, was one of the first significant approvals and has been widely used in combination with chemotherapy. More recently, bispecific antibodies like Blinatumomab, which targets CD19 and CD3, have been approved for certain types of NHL. These therapies work by engaging T-cells to target and kill B-cell malignancies. Mosunetuzumab, currently under investigation, similarly targets CD20 and CD3, representing a promising advancement in the treatment landscape for relapsed or refractory aggressive B-cell lymphomas.

What other types of research exist?

Promising novel alternatives to Mosunetuzumab for Non-Hodgkin's Lymphoma patients include: 1) CAR T-cell therapies such as Axicabtagene Ciloleucel and Tisagenlecleucel, which have shown significant efficacy in relapsed or refractory NHL. 2) Bispecific T-cell engagers (BiTEs) like Blinatumomab, which target CD19 and CD3. 3) Antibody-drug conjugates (ADCs) such as Polatuzumab Vedotin, which targets CD79b. 4) Novel BTK inhibitors like Zanubrutinib and Acalabrutinib, which offer improved tolerability and efficacy profiles. These therapies represent cutting-edge advancements in the treatment of NHL and are expected to be significant options in 2024.

Summary

This trial tests adding mosunetuzumab to strong chemotherapy for patients with aggressive B cell lymphoma who haven't responded to other treatments. The drug helps the immune system find and kill cancer cells, aiming to improve treatment before a stem cell transplant. Mosunetuzumab has shown promising results in recent trials.

Who is the study for?

This trial is for adults with certain aggressive B cell lymphomas that have come back or didn't respond to initial treatments. They should be planning an autologous stem cell transplant and must not have had more than two prior chemotherapy lines. Participants need normal blood counts, no major recent surgeries, and can't be pregnant or breastfeeding. Those with autoimmune diseases, a history of severe allergies to monoclonal antibodies, active infections, or liver disease are excluded.

What is being tested?

The study tests mosunetuzumab combined with platinum-based salvage chemotherapy (DHAX or ICE) in patients aiming for stem cell transplantation. It's designed to see if this combination is safe and potentially better than current chemoimmunotherapy options that use rituximab retreatment.

What are the potential side effects?

Mosunetuzumab may cause side effects like infusion reactions (symptoms during or after the drug is given), low blood counts leading to increased infection risk, tiredness, and potential organ inflammation. The exact side effects will vary from person to person.

Experimental Treatment

Group I: Arm B: Mosunetuzumab + ICEExperimental Treatment2 Interventions

* 3 cycles (cycle=21 days) of mosunetuzumab with ICE salvage chemotherapy (selected at the discretion of the treating physician). * The first 3 patients in each arm will receive Dose Level 1 along with standard dosing of ICE. The rate of dose-limiting toxicities will determine whether the subsequent 3 patients in each arm are enrolled at Dose Level 1, or alternatively at Dose Level -1. * For patients tolerating Cycle 1 of treatment, Cycles 2 and 3 will consist of mosunetuzumab administered as a single dose on Day 1 along with ICE. Patients will undergo PET-CT restaging prior to Cycle 3, and those achieving a CR (or PR, at their physician's discretion) will receive the Cycle 3 dose of mosunetuzumab and ICE, followed by standard of care stem cell mobilization and autoSCT. Patients with SD or PD after restaging will discontinue study treatment.

Group II: Arm A: Mosunetuzumab + DHAXExperimental Treatment2 Interventions

* 3 cycles (cycle=21 days) of mosunetuzumab with DHAX salvage chemotherapy (selected at the discretion of the treating physician). * The first 3 patients in each arm will receive Dose Level 1 along with standard dosing of DHAX. The rate of dose-limiting toxicities will determine whether the subsequent 3 patients in each arm are enrolled at Dose Level 1, or alternatively at Dose Level -1. * For patients tolerating Cycle 1 of treatment, Cycles 2 and 3 will consist of mosunetuzumab administered as a single dose on Day 1 along with DHAX. Patients will undergo PET-CT restaging prior to Cycle 3, and those achieving a CR (or PR, at their physician's discretion) will receive the Cycle 3 dose of mosunetuzumab and DHAX, followed by standard of care stem cell mobilization and autoSCT. Patients with SD or PD after restaging will discontinue study treatment.

Other Research

The most common treatments for Non-Hodgkin's Lymphoma (NHL) include monoclonal antibodies, chemotherapy, and targeted therapies. Monoclonal antibodies like rituximab target CD20 on B-cells, leading to their destruction. Chemotherapy uses cytotoxic drugs to kill rapidly dividing cells, including cancerous lymphocytes. Targeted therapies, such as ibrutinib, inhibit specific proteins involved in cancer cell growth and survival. Mosunetuzumab, a bispecific antibody, targets both CD20 on B-cells and CD3 on T-cells, bringing them together to enhance the immune system's ability to kill cancer cells. These mechanisms are crucial for NHL patients as they offer multiple strategies to eliminate cancer cells, potentially improving treatment efficacy and patient outcomes.
