About
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.
Full 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. Pembrolizumab is an anti-PD-1 immunotherapy that is given intravenously and is approved for treatment of malignant NSCLC. Idelalisib is the first-in-class oral PI3K-δ inhibitor that is approved for treatment of certain forms of leukemia and lymphoma.
Immune checkpoint inhibitors (such as anti-PD-1) are effective in treating NSCLC as a single agent, but overall response isn't optimal; overall response rates (ORR) are only ~20% on average. The goal of this study is to see whether combining standard therapy with additional immune modulators will increase response rates, compared to the response seen with pembrolizumab monotherapy.

Inclusion and exclusion criteria
All subjects must have documented metastatic or recurrent NSCLC from biopsy. They must have failed or progressed on platinum-based chemotherapy (e.g. cisplatin, carboplatin) as well as immune checkpoint inhibitor therapy (e.g nivolumab or pembrolizumab). Patients with EGFR/ALK mutations/translocations must have failed or progressed on small molecule inhibitor therapies (e.g. erlotinib, afatinib, etc.).
