Brief summary

This is a phase I/II study for previously untreated subjects with advanced NSCLC. The study will take place in two phases. First, a cohort of twelve participants will be enrolled in phase I part and will be treated with carboplatin, nab-paclitaxel and pembrolizumab. A cohort of twelve subjects will be evaluated for safety and tolerability after 2 cycles of therapy. All subjects who receive either nab-paclitaxel or pembrolizumab will be evaluable. If 33% of subjects or less have unacceptable toxicity in the first cohort or any subsequent cohort (if necessary), the study will proceed to the Phase II part. If more than 33% have unacceptable toxicity, 12 additional subjects will be enrolled in a second cohort, if necessary. If unacceptable toxicity is seen in more than 33% in Cohort 2, the study will end due to unacceptable toxicity of this drug combination. The phase II part of the study is a single arm study. All subjects will be treated with carboplatin, nab-paclitaxel, and pembrolizumab in 21-day cycles for up to 4 cycles. Mandatory pre-treatment tumor biopsies will be obtained prior to initiating treatment for all subjects (only if adequate archived samples are unavailable). Mandatory tumor biopsies will be obtained in the Phase II part of the study after 4 cycles of study treatment or at the time of progression, whichever comes first. For subjects without progression of disease after Cycle 4, pembrolizumab will continue every 3 weeks for up to 2 years or until unacceptable toxicity.

Subjects who complete 24 months of treatment with pembrolizumab may be eligible for up to one year of additional study treatment if they progress after stopping study treatment provided they continue to meet inclusion criteria requirements. Phase II Induction Therapy: * Carboplatin AUC 6 IV, Day 1 * Nab-paclitaxel 100 mg/m\^2 IV, Days 1, 8, 15 * pembrolizumab 200mg IV, Day 1 of each cycle * Cycle length: 21 days; number of cycles: 4 Phase II Maintenance Therapy: For subjects who have confirmed CR, PR, or SD (non-progression) after 4 cycles of induction therapy, maintenance therapy with pembrolizumab 200 mg will continue on Day 1 of each 21-day cycle.

Induction Therapy Cycles 1-4 Subjects will be treated with carboplatin AUC 6 given IV on Day 1, nab-paclitaxel 100 mg/m2 given IV on Days 1, 8, and 15, and pembrolizumab 200 mg IV on Day 1. Treatment will continue for a maximum duration of 4 cycles of study treatment. Each cycle starts when all the criteria to start a new cycle are met. A cycle is defined only when you can give all 3 drugs on Day 1, and it coincides with pembrolizumab. Pembrolizumab should be given with carboplatin and nab-paclitaxel on day 1 of the cycle. Chemotherapies may be withheld for six weeks, while pembrolizumab can be withheld for 12-weeks. If there is a pembrolizumab-specific toxicity requiring pembrolizumab to be held, chemotherapy should be resumed without pembrolizumab within 6 weeks if it is felt that chemotherapy is safe by the site investigator. Delays in chemotherapy beyond 6 weeks require withdrawal from the study treatment. Maintenance Therapy For subjects who have confirmed CR, PR, or SD (non-progression) after 4 cycles of induction therapy, maintenance therapy with pembrolizumab 200 mg will continue on Day 1 of each 21-day cycle. Treatment will continue until progression of disease, unacceptable toxicity, or for a maximum of 2 years from Cycle 1 Day 1.
