Clinical Trial of Ublituximab and Umbralisib With CHOP (U2-CHOP) Followed by U2 Maintenance (U2-CHOP-U2) in Previously Untreated Mantle Cell Lymphoma (MCL)

• Status: Recruiting
• Trial end date: 2025-06-30
• Target enrollment: 0
• Participant gender: All

Summary

This is a single arm, multi-center, open label Phase Ib/II trial in adult patients with newly diagnosed Mantle Cell Lymphoma (MCL)(Stage II-IV). The Diagnosis of MCL (Stage II, III, IV) is supported by histology and over expression of cyclin D1 or by FISH (fluorescent in situ hybridization). In the proposed study, the primary endpoint is to estimate the biological response rate of the combination of Umbralisib at dose 800 mg with Ublituximab (900mg)-Cyclophosphamide, Doxorubicin, Vincristine and Prednisone (CHOP), but a phase Ib portion with dose de-escalation at two does level (800 and 600 mg) will be built in to further confirm its safety and tolerability. Treatment will be administered on an outpatient basis in 3-week (21 day) cycles. Once Umbralisib dose is defined in phase Ib, the study will expand to phase II portion after SMC/DSMB (Safety monitoring committee/Data Safety Monitoring Committee) agreement.

• All patients (or their legal representative) must have signed an informed consent indicating that they are willing to participate in the study and are willing to follow the procedure required by the study in accordance with federal, local and institutional guidelines.

• Female patients who are not of child-bearing potential, and female patients of child-bearing potential who have a negative serum pregnancy test within 3 days prior to initial trial treatment Female patients of child-bearing potential and all male partners must consent to use a medically acceptable method of contraception throughout the study period and for 4 months after the last dose of either study drug.

Exclusion Criteria:

• Any prior anti-neoplastic therapy for MCL

• CNS involvement by MCL
