Official Title
A Phase Ib, Open-Label, Multicenter Study Evaluating the Safety and Efficacy of Glofitamab or Mosunetuzumab in Combination With Gemcitabine Plus Oxaliplatin in Patients With Relapsed or Refractory Diffuse Large B-Cell Lymphoma and High-Grade Large B-Cell Lymphoma
Study Summary
This study is designed to evaluate the safety and efficacy of glofitamab or mosunetuzumab in combination with gemcitabine and oxaliplatin (Glofit-GemOx or Mosun-GemOx) in participants with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) or high-grade B-cell lymphoma (HGBCL).
Eligibility Criteria
All
≥18 Years
No
Inclusion Criteria
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0,1, or 2
- Histologically confirmed B-cell lymphoma, including one of the following diagnoses per the 2016 World Health Organization (WHO) classification of lymphoid neoplasms: DLBCL, not otherwise specified (NOS); HGBCL with MYC and BCL2 and/or BCL6 rearrangements; HGBCL, NOS
- R/R disease, defined as follows: Relapse: disease that has recurred following a response that lasted >/=6 months after completion of last line of therapy; Refractory: disease that progressed during therapy or progressed within 6 months (<6 months) of prior therapy
- At least one line of prior systemic therapy
- At least one bi-dimensionally measurable nodal lesion or one bi-dimensionally measurable extranodal lesion, as measured on positron emission tomography-computed tomography (PET/CT) scan
- Adequate hematologic function
- For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods, and agreement to refrain from donating eggs, as follows: Women must remain abstinent or use contraceptive methods with a failure rate of <1% per year during the treatment period and for at least 18 months after the final dose of obinutuzumab, 6 months after the final dose of gemcitabine, 9 months after the final dose of oxaliplatin, 3 months after the final dose of mosunetuzumab, 3 months after the final dose of tocilizumab, and 2 months after the final dose of glofitamab. Women must refrain from donating eggs during this same period
- For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods, and agreement to refrain from donating sperm, as follows: With a female partner of childbearing potential or pregnant female partners, men must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of <1% per year during the treatment period and for at least 2 months after the final dose of glofitamab, 2 months after the final dose of mosunetuzumab, 2 months after the final dose of tocilizumab (if applicable), 3 months after the final dose of obinutuzumab, and 6 months after the final dose of oxaliplatin or gemcitabine to avoid exposing the embryo. Men must refrain from donating sperm during this same period.
