PG - 1-6 LID - 10.1080/10428194.2024.2325636 [doi] AB - Lenalidomide and rituximab (R(2)) is an effective frontline treatment for patients with indolent B-cell non-Hodgkin lymphoma (iNHL). We investigated the safety and efficacy of addition of the proteasome inhibitor ixazomib to R(2) for treatment of iNHL through a phase I/II clinical trial for high-risk patients. Twenty patients were enrolled, 18 were treated. The target dose of ixazomib 4 mg weekly was achieved during dose escalation. The most common treatment-related adverse events (AEs) were low grade gastrointestinal, rash, neuropathy, and myalgia/arthralgia. There were 33% grade 2 and 17% grade 3 infections. With median follow-up of 5.2 years, four patients discontinued treatment due to lymphoma progression. Best overall response rate (ORR) was 61.2% [55.6% CR, 5.6% PR): 22.2% had stable disease and 16.7% had disease progression. Kaplan-Meier estimates of progression free and overall survival (OS) were 73% and 87% at 36 months, respectively. R(2) can safely be combined with ixazomib for treatment-naive iNHL patients.
