Trial Summary

What is the purpose of this trial?

BrUOG-401 is a prospective, single-arm, phase 2 trial of first-line therapy in adult patients with previously untreated FL or MZL. All patients will be assigned the same initial treatment plan, modified by interim response assessment (IRA) after Cycle 4. All patients will start treatment with four 21-day cycles (C1-4) of mosunetuzumab alone (using step-up dosing during C1), followed by IRA. Patients who achieve CR at IRA will continue with additional 4 cycles (C5-8) of mosunetuzumab. Patients who achieve PR at IRA will receive mosunetuzumab with lenalidomide augmentation during C5-8. Primary response assessment (PRA) will occur after C8. Patients who remain in PR at PRA will continue for additional 4 cycles (extended augmentation).

Do I need to stop my current medications to join the trial?

The trial does not specify if you need to stop taking your current medications. However, you cannot use systemic immunosuppressive medications, except for low-dose corticosteroids, before starting the trial.

What data supports the effectiveness of the drug combination Mosunetuzumab and Lenalidomide for treating lymphoma?

Lenalidomide has shown significant effectiveness in treating various types of B-cell non-Hodgkin lymphoma, both as a single drug and in combination with other treatments, like monoclonal antibodies. It has been particularly effective in relapsed or refractory cases, suggesting potential benefits when combined with other drugs like Mosunetuzumab for lymphoma treatment. ^{1 2 3 4 5}

Is the combination of Mosunetuzumab and Lenalidomide safe for humans?

Mosunetuzumab and Lenalidomide have been studied separately and in combination with other drugs for lymphoma, showing a generally favorable safety profile. Common side effects include neutropenia (low white blood cell count), fatigue, and cytokine release syndrome (a reaction that can cause fever and low blood pressure), but these are often manageable. Both drugs have been used safely in various lymphoma treatments, suggesting they are generally safe for humans. ^{3 6 7 8 9}

How is the drug Mosunetuzumab + Lenalidomide unique for treating lymphoma?

Mosunetuzumab is a novel drug that engages T-cells to target and destroy cancer cells, making it a potent option for relapsed or refractory follicular lymphoma. When combined with lenalidomide, an oral drug that modifies the immune system, this treatment offers a unique approach by enhancing the immune response against lymphoma cells, providing an 'off-the-shelf' option with manageable side effects. ^{1 3 4 6 10}

Trial Timeline

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

Participants receive mosunetuzumab alone for four 21-day cycles, followed by interim response assessment. Depending on response, treatment continues with mosunetuzumab alone or with lenalidomide augmentation for additional cycles.

24 weeks

Primary Response Assessment

Primary response assessment occurs after Cycle 8 to evaluate complete response rate.

1 week

Extended Augmentation

Participants who remain in partial response at primary response assessment continue for additional 4 cycles with extended augmentation.

12 weeks

Follow-up

Participants are monitored for progression-free survival and other outcomes.

Approximately 5 years

Treatment Details

Interventions

• Lenalidomide (Immunomodulatory Agent)
• Mosunetuzumab (Monoclonal Antibodies)

Trial Overview The trial tests mosunetuzumab alone for four cycles followed by an interim response assessment (IRA). Depending on IRA results (complete response or partial response), patients may continue with mosunetuzumab alone or receive it augmented with lenalidomide for another four cycles. The primary response is assessed after eight cycles.

Findings from Research

Lenalidomide is an effective oral immunomodulator approved for treating relapsed/refractory mantle cell lymphoma (MCL) after two prior therapies, showing significant activity in various B-cell non-Hodgkin lymphomas (NHL).

Combining lenalidomide with rituximab (R2) has demonstrated promising results in both first-line and relapsed/refractory settings, and ongoing trials are evaluating its use in combination with immunochemotherapy regimens like R-CHOP.

In a study of 33 patients with relapsed/refractory non-Hodgkin lymphoma, the GROC-Rev chemotherapy regimen followed by lenalidomide maintenance therapy resulted in a 61% overall response rate, with 39% achieving complete response (CR).

The treatment was generally well-tolerated, although some patients experienced significant adverse events like neutropenia and infections, highlighting the need for careful monitoring during therapy.

Mosunetuzumab: First Approval. Kang, C.[2022]

The combination of oral lenalidomide and obinutuzumab was found to be well tolerated and effective in treating relapsed or refractory follicular lymphoma, with a response rate of 63.2% among participants.

The study established a recommended dose of lenalidomide at 20 mg, as higher doses increased the risk of grade 3/4 neutropenia, although no maximum tolerated dose was reached during the trial.
