Non Hodgkin Lymphoma Clinical Trial

A Study to Learn About the Effects of Two Study Medicines (Maplirpacept [PF-07901801] And Glofitamab) When Given Together In People With Relapsed Or Refractory Diffuse Large B Cell Lymphoma.

Summary

The purpose of this study is to learn about the effects of two study medicines (maplirpacept [PF-07901801] and glofitamab) when given together for the treatment of diffuse large B-cell lymphoma (DLBCL) that is relapsed or is refractory. Relapsed means has returned after last treatment. Refractory means that it has not responded to last treatment. The two study medicines are given after a single dose of obinutuzumab which is the third study medicine.

DLBCL is a type of non-Hodgkin lymphoma (NHL). NHL is a cancer of the lymphatic system. It develops when the body makes abnormal B lymphocytes. These lymphocytes are a type of white blood cell that normally help to fight infections.

This study is seeking adult participants who:

Have histologically confirmed diagnosis of DLBCL
Have received at least one first line of treatment for NHL.
Are unable or unwilling to undergo a stem cell transplant or CAR-T cell therapy.

Stem cell transplant is a procedure in which a patient receives healthy blood-forming cells to replace their own stem cells that have been destroyed by treatment.

A CAR-T therapy is a type of treatment in which a patient's T cells are changed in the laboratory so they will attack cancer cells.

Everyone in this study will receive all three medicines at the study site by intravenous (IV) infusion which is given directly into a vein. The two study medicines (maplirpacept [PF-07901801] and glofitamab) will be given in 21-day cycles.

At Cycle 0, participants will receive a single dose of obinutuzumab pre-treatment followed by two step-up doses of glofitamab. The combination of maplirpacept (PF-07901801) with glofitamab full dose will be administered for the first time at Cycle 1 Day 1.

Maplirpacept (PF-07901801) will be given weekly for the first three cycles and then every three weeks. Glofitamab will be given every 3 weeks for approximately 9 months. Thereafter participants will continue to receive maplirpacept alone.

Maplirpacept (PF-07901801) will be given at different doses to different participants. Everyone taking part will receive the same fixed doses of glofitamab and obinutuzumab studied in patients with DLBCL.

The study will compare the experiences of people receiving different doses of maplirpacept (PF-07901801). This will help to determine what dose is safe and effective when given with the other 2 study medicines.

Full Description

This is a multicenter, open-label, Phase 1b/2 study to evaluate the safety, tolerability and potential clinical benefits of maplirpacept PF-07901801, an anti-CD47 molecule, in combination with fixed doses of glofitamab after a single dose of obinutuzumab in participants with relapsed/refractory (R/R) DLBCL not eligible for or unwilling to undergo high dose chemotherapy and subsequent autologous stem cell transplantation (ASCT) or unable to receive approved chimeric antigen receptor T-cell (CAR-T) therapy (for example, due to logistical limitations).

For Phase 1b, participants must have previously received at least 1 prior systemic treatment regimen. For Phase 2, participants must have received at least 1 but no more than 2 prior systemic treatment regimens. All participants must have previously received an anti-CD20 containing regimen.

Phase 1b will assess dose-limiting toxicities of PF-07901801 when administered in combination with glofitamab, to select up to 2 doses for the Phase 2 part of the study. Phase 2 will evaluate safety and efficacy to determine the recommended Phase 3 dose of PF-07901801 to be administered in combination with glofitamab.
