Number of Participants With Dose-Limiting Toxicity (DLT) Events as Assessed by CTCAE v4.03Primary· First 9 weeks at each dose level
Modified 3+3 dose escalation design will be used to determine whether the addition of idelalisib to standard pembrolizumab is safe and tolerable in checkpoint inhibitor refractory NSCLC patients. An initial cohort of 3 patients will receive 50 mg twice daily idelalisib with standard pembrolizumab. If none of the 3 patients develop a DLT, another 3 patients will be enrolled. Dose will be escalated or de-escalated based on the occurrence of DLTs. All events will be assessed for possible, probable, or definite relation to idelalisib.

Dose-Finding Assessment for Optimum Dose of Idelalisib in Combination With PembrolizumabSecondary· 18-27 weeks
Determine the phase 2 recommended dose (P2RD) of idelalisib, in combination with pembrolizumab, in patients with checkpoint inhibitor refractory NSCLC. If no more than 1/6 patients in initial cohort develop a DLT, the patients will be tested for T-regulatory cell function suppression (80% suppression in 80% of patients). If dose is escalated or de-escalated, testing will continue to assess for optimal T-reg suppression. The dose at which the tolerability and suppression criteria are both met will be declared the P2RD and the study will proceed to phase 2.

Sponsor's own description
This is a phase 1b/2 study to determine the safety and effectiveness of the combination of pembrolizumab and idelalisib in NSCLC patients whose disease has stopped responding to immune therapy. This study is being done to see if adding another immune modulator (idelalisib) to standard pembrolizumab will increase response rates, compared to the response seen with pembrolizumab alone.
