Non-Small Cell Lung Cancer (NSCLC) NSCLC divided into: Squamous (epidermoid carcinoma): ~25% of all NSCLC Non-Squamous: ~75% of all NSCLC Adenocarcinoma: cancer that originates from the mucus secreting cells, most common form Large cell (undifferentiated) carcinoma: heterogenous epithelial neoplasms Other types: occur less frequently NSCLC constitutes 85% to 90% of all lung cancers (sources: Seer Cancer Statistics, http://seer.cancer.gov/statfacts/html/lungb.html; American Cancer Society, http://www.cancer.org/cancer/lungcancer-non-smallcell/)

Non-Small Cell Lung Cancer Treatment NCCN Guidelines® recommend the anti-PD-1 inhibitor, nivolumab, for treating patients with Non-Small Cell Lung Cancer (NSCLC) with progression on or after platinum-based chemotherapy 1st Line 2nd Line Advanced or metastatic NSCLC: Non-Mutation Driven* Treatment algorithm Non-Squamous Squamous Chemotherapy (e.g. cisplatin / pemetrexed) +/- bevacizumab Nivolumab Docetaxel +/- ramucirumab Pemetrexed Other chemotherapy Nivolumab Docetaxel +/- ramucirumab Pemetrexed Other chemotherapy Chemotherapy (e.g. cisplatin / gemcitabine) *Targeted therapies are also an option for patients with EGFR (epidermal growth factor receptor) mutations or ALK (anaplastic lymphoma kinase) rearrangements
Slide 5-

Immunotherapy checkpoint inhibitors: the New Players in the NSCLC space Checkpoint inhibitors: tumors express “checkpoint” proteins on their cell surface to escape detection from the immune system; targeted inhibition towards these receptors enhances T cell response towards the tumor (source: taken from: http://sitn.hms.harvard.edu/flash/2014/blocking-the-brakes-helping-your-immune-system-battle-cancer/
Slide 6-

PD-L1Expression as a Potential Biomarker Expression of PD-L1 on tumor-infiltrating immune cells or tumor cells may potentially be used as a biomarker to predict anti-tumor response to PD-1 / PD-L1 inhibitors Several clinical trials are assessing the role of PD-L1 expression on the clinical activity of PD-1 / PD-L1 inhibitors to determine if higher expression correlates definitively with increased clinical activity (discussed in the following slides) and, if so, what the implications are for the effective and appropriate use of anti-PD1s in patients who are PD-L1+ or who are PD-L1 -
Slide 7-

Checkpoint inhibitor nivolumab was approved by the FDA to treat patients with squamous NSCLC as subsequent therapy Phase III, randomized, open-label study (n=272), nivolumab vs. docetaxel; metastatic squamous NSCLC, disease progression during or after one prior platinum doublet based chemotherapy Median Overall Survival (OS) = 9.2 months on nivolumab (n=132) vs. 6.0 months on docetaxel (n=137) CheckMate 017 Trial CheckMate 063 Trial Phase II, single-arm study, nivolumab (n=117); progression after a platinum-based therapy and at least one additional systemic treatment Objective Response Rate (ORR) = 15%, all partial responses, median time to onset of response = 3.3 months 76% (13 of 17 patients) with a confirmed response had ongoing responses, 10 of the 17 had durable responses of 6 months or longer Common adverse events (in at least 20% of patients, reported from Phase II trial): fatigue, dyspnea, musculoskeletal pain, decreased appetite, cough, nausea, and constipation sources: label; Rizvi, et al.

Nivolumab is being studied for additional indications in Non-Squamous Non-Small Cell Lung Cancer CheckMate 057 Trial Pivotal Phase III, randomized, open-label study (n=582), nivolumab vs. docetaxel in previously treated patients with advanced non-squamous NSCLC Median OS = 12.2 months with nivolumab compared to 9.4 months with docetaxel ORR was 19% vs. 12% and median DOR was 17.2 months vs. 5.6 months with nivolumab vs. docetaxel, respectively Higher PD-L1 expression correlated with higher improved survival; PD-L1 expression > 1% in tumor cells improved median OS by 41%; no difference in survival in PD-L1 non-expressors Nivolumab had a better adverse event profile compared to docetaxel; Grade 3-4 AEs were 10% with nivolumab vs. 54% with docetaxel Other selected ongoing trials: Trial stopped early because the study met its primary endpoint of superior overall survival sources: J Clin Oncol. 2015 33 (suppl; abstr LBA 109); clinicaltrials.gov NCT02041533, NCT02323126

Additional PD-1 / PD-L1 inhibitors in development to treat patients with NSCLC Merck’s Pembrolizumab (Keytruda): Human monoclonal antibody directed against the programmed death-1 (PD-1) receptor of the T Cell; binding to PD-1 blocks its interaction with programmed cell death ligand 1 (PD-L1) and PD-L2 on the tumor cell; pembrolizumab received breakthrough designation by the FDA; FDA approved for melanoma AstraZeneca’s MEDI4736: Human monoclonal antibody directed against programmed cell death ligand 1 (PD-L1). PD-L1 binds to the PD-1 receptor, releasing PD-1 pathway-mediated inhibition of the immune response, including the anti-tumor immune response Genentech’s MPDL3280A: Human monoclonal antibody directed against programmed cell death ligand 1 (PD-L1). PD-L1 binds to the PD-1 receptor, releasing PD-1 pathway-mediated inhibition of the immune response, including the anti-tumor immune response anti- PD-1 anti- PD-L1
