Efficacy and Safety Study of Idelalisib in Participants With Indolent B-Cell Non-Hodgkin Lymphomas

Summary

The primary objective will be to assess the overall response rate and to evaluate the efficacy and safety of idelalisib (IDELA; GS-1101) in participants with previously treated indolent Non-Hodgkin Lymphoma (iNHL) that is refractory both to rituximab and to alkylating-agent-containing chemotherapy. Eligible participants will initiate oral therapy with idelalisib at a starting dose of 150 mg taken twice per day. Treatment with idelalisib can continue in compliant participants as long as the study is still ongoing and the participants appear to be benefiting from treatment with acceptable safety.
