Trial Summary

What is the purpose of this trial?

This trial is testing a new drug called RO7227166, given through an IV, along with two other drugs, obinutuzumab and glofitamab. Obinutuzumab is a monoclonal antibody recently approved for treating follicular lymphoma that has relapsed or was refractory to a rituximab-containing regimen. It targets patients whose Non-Hodgkin's Lymphoma has come back or didn't respond to previous treatments. The goal is to see if this combination can help the immune system fight the cancer more effectively.

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

The trial protocol does not specify if you need to stop taking your current medications. However, you must not have received certain treatments like systemic immunotherapeutic agents or chemotherapy within 4 weeks before starting the trial. It's best to discuss your specific medications with the trial team.

What data supports the effectiveness of the drug combination RO7227166, Obinutuzumab, and Glofitamab for Non-Hodgkin's Lymphoma?

Research shows that Obinutuzumab, a part of this drug combination, has been effective in treating follicular lymphoma, especially in patients who did not respond to or relapsed after other treatments. It has been shown to improve progression-free survival and overall survival when combined with other drugs in clinical studies. ^{1 2 3 4 5}

What safety data exists for Obinutuzumab in treating Non-Hodgkin's Lymphoma?

Obinutuzumab, used in treating Non-Hodgkin's Lymphoma, generally has manageable side effects, with mild to moderate infusion-related reactions (like fever or chills during the drug infusion) being common. More serious side effects include neutropenia (a drop in white blood cells), but these are less frequent. ^{2 3 5 6 7}

What makes the drug combination of RO7227166, Obinutuzumab, and Glofitamab unique for treating Non-Hodgkin's Lymphoma?

This drug combination is unique because it includes Obinutuzumab, a novel anti-CD20 antibody that has shown improved efficacy over rituximab, especially in patients who are resistant to rituximab. Obinutuzumab is designed to induce strong direct cell death and enhance the immune system's ability to kill cancer cells, making it a promising option for difficult-to-treat cases of Non-Hodgkin's Lymphoma. ^{2 3 4 5 8}

Eligibility Criteria

This trial is for adults with relapsed/refractory B-Cell Non-Hodgkin's Lymphoma who've had at least two prior treatments and have no other survival-prolonging options. They must not be pregnant or breastfeeding, agree to contraception requirements, have a life expectancy of over 12 weeks, and good organ function. Exclusions include active infections, recent major surgery or immunotherapy, certain cardiovascular diseases, and CNS lymphoma.

Inclusion Criteria

Life expectancy of >/= 12 weeks

I can provide a fresh biopsy from a site that is safe to access, as long as I have more than one measurable lesion.

Side effects from my previous cancer treatments are mild or gone.

Exclusion Criteria

I haven't had cancer treatment within the last 4 weeks or before the drug's half-life period, whichever is shorter, before starting obinutuzumab.

I've had side effects from previous immune treatments or have an autoimmune disease.

I have a serious heart condition.

Interventions

• Glofitamab (Monoclonal Antibodies)
• Obinutuzumab (Monoclonal Antibodies)
• RO7227166 (Other)

Trial Overview The study tests RO7227166 combined with obinutuzumab and glofitamab in people with specific lymphomas. It starts with a pre-treatment dose of obinutuzumab followed by the main drugs in escalating doses to find safe levels (Phase I/II) before expanding to more patients (Phase III).

Participant Groups

Group I: Part III Experimental Treatment 4 Interventions

Dose-Expansion Stage: Participants with r/r diffuse large B-cell lymphoma not otherwise specified (DLBCL NOS), high-grade B-cell lymphoma (HGBCL), primary mediastinal B-cell lymphoma (PMBCL), and DLBCL arising from FL (transformed FL) will receive englumafusp alfa administered by IV infusion in combination with glofitamab in a three-weekly schedule (Q3W).

Group II: Part II Experimental Treatment 4 Interventions

Combination Dose-Escalation: Mixed r/r participants and participants with mixed r/r mantle cell lymphoma (MCL) and Richters transformation will receive a fixed dose of obinutuzumab seven days prior to first administration of englumafusp alfa. Englumafusp alfa will be administered by IV infusion in combination with glofitamab in a three-weekly schedule (Q3W).

Group III: Part I Experimental Treatment 3 Interventions

Combination Dose-Escalation: Mixed r/r NHL participants will receive a fixed dose of obinutuzumab up to seven days prior to first administration of englumafusp alfa. Englumafusp alfa will be administered by intravenous (IV) infusion in combination with obinutuzumab in a three-weekly schedule (Q3W).

Findings from Research

In a phase 2 study involving 89 patients with relapsed or refractory follicular lymphoma, 79% achieved an overall response after treatment with lenalidomide and obinutuzumab, demonstrating significant efficacy in this patient population.

The treatment had a manageable safety profile, with common adverse events including neutropenia and asthenia, and serious adverse events reported in 34% of patients, indicating that while effective, careful monitoring for side effects is necessary.
