Idelalisib in Combination With Rituximab for Previously Untreated Follicular Lymphoma and Small Lymphocytic Lymphoma

Phase 2TerminatedNCT02258529

Gilead Sciences10 enrolled

Overview

The primary objective of this study is to evaluate the overall response rate (ORR) and complete response (CR) rate to treatment with idelalisib in combination with rituximab in previously untreated adults with follicular lymphoma (FL) or small lymphocytic lymphoma (SLL). An increased rate of deaths and serious adverse events (SAEs) among participants with front-line chronic lymphocytic leukemia (CLL) and early-line indolent non-Hodgkin lymphoma (iNHL) treated with idelalisib in combination with standard therapies was observed by the independent data monitoring committee (DMC) during regular review of 3 Gilead Phase 3 studies. Gilead reviewed the unblinded data and terminated those studies in agreement with the DMC recommendation and in consultation with the US Food and Drug Administration (FDA). All front-line studies of idelalisib, including this study, were also terminated.

Outcomes

Primary Outcomes

Overall Response Rate

Overall response rate (ORR) was defined as the proportion of participants who achieve a confirmed complete or partial response during idelalisib treatment. ORR was to be assessed by an independent review committee (IRC).

Secondary Outcomes

Overall Safety Profile of Idelalisib as Measured by the Incidence of Adverse Events (AEs), Severe AEs (SAEs), AEs Leading to Idelalisib (IDL) Interruption, Idelalisib Dose Reduction, Premature Discontinuation of Idelalisib, or Death

Time frame: Up to 24 weeks plus 30 days

Rate of Grade ≥ 3 Transaminase Elevations Based on Laboratory Findings

The rate of Grade ≥ 3 transaminase elevations was defined as the number of participants with any Grade 3 or 4 alanine aminotransferase (ALT) or aspartate aminotransferase (AST) elevations.

Time frame: Up to 24 weeks plus 30 days

Idelalisib Trough and Peak Plasma Concentrations

Time frame: Predose and 1.5 hour postdose at Weeks 2, 4, and 12

Time to Response

Time to response was defined as the the interval from the start of idelalisib treatment to the first documentation of complete or partial response.

Duration of Response

Duration of response (DOR) was defined as the interval from the first documentation of complete response or partial response to the earlier of the first documentation of disease progression or death from any cause.

Progression-Free Survival

Progression-free survival (PFS) was defined as the interval from the start of idelalisib treatment to the earlier of the first documentation of disease progression or death from any cause.

Overall Survival

Overall survival was defined as the interval from enrollment to death from any cause.

Changes in Health-Related Quality of Life

Changes in health-related quality of life was to be reported by participants using the Functional Assessment of Cancer Therapy - Lymphoma (FACT-Lym) questionnaire.
