• 1 other identifier: 2023LS183
• Study Type: interventional
• Target: 65
• Locations: 1 country
• Sites: 1

Brief Summary

The study follows a Simon's two-stage phase II trial design to evaluate the safety and efficacy of tafasitamab added to rituximab and lenalidomide for two treatment-naïve, parallel, independent cohorts: follicular lymphoma (FL) and marginal zone lymphoma (MZ). Each cohort, FL and MZ, will be evaluated separately. This study is presented to the patient and consent is signed prior to the initiation of treatment for their primary malignancy.

Conditions

Follicular Lymphoma; Marginal Zone Lymphoma

Outcome Measures

Primary Outcomes (1)

• Complete response (CR)

  Estimate complete response (CR) at the end of study (after 12 cycles around 1 year) regimen of tafasitamab with lenalidomide and rituximab.

Secondary Outcomes (6)

• Complete response (CR)

  6 months

• Overall response rate (ORR)

  1 year

• Progression of disease (POD24)

  2 years

• Progression free survival (PFS)

  3 years

• Overall survival (OS)

Study Arms (2)

Follicular Lymphoma

EXPERIMENTAL

On Cycle 1, patients will receive an infusion of tafasitamab 12 mg/kg IV on Day 1, Day 8, Day 15 and day 22, rituximab 375 mg/m2 IV on Day 1, Day 8, Day 15 and Day 22, and lenalidomide 20 mg PO Day 1 through Day 21. On Cycles 2-3, patients will receive tafasitamab 12 mg/kg IV on Day 1, Day 8, Day 15 and day 22, rituximab 375 mg/m2 IV on day 1, and lenalidomide 20 mg PO Day 1-21. On Cycles 4-6, patients will receive an infusion of tafasitamab 12 mg/kg IV on Day 1, Rituximab 375 mg/m2 IV on Day 1, and lenalidomide 20 mg PO from Day 1-21. At the end of Cycle 6, patients on both cohorts will be assessed by Lugano standard. Patients in complete remission (CR) will continue on tafasitamab/rituximab and discontinue lenalidomide. Patients with partial response (PR) or stable disease (SD) will continue on all three drugs, tafasitamab/rituximab/lenalidomide, and if progressive disease (PD) will discontinue study.
