ALT-803, an IL-15 superagonist, in combination with nivolumab in metastatic non-small cell lung cancer: Ongoing experience and biomarker development from a non-randomized, open-label, phase Ib/II trial.

John Wrangle, M.D., MPH

PD-1/PD-L1 blockade fails to yield a response in about 80% of unselected non-small cell lung cancer (NSCLC) patients and acquired resistance will lead to treatment failure in most responders. Cytokine therapy with IL-2/IL-15Rbg agonists has demonstrated durable responses in select solid tumors, though the response rates are low. In this phase Ib/II trial NSCLC patients received anti-PD1 immunotherapy in combination with ALT-803, an IL-15 super-agonist. There is encouraging anti-tumor activity with the combination of nivolumab with ALT-803. Phase II study of the combination is ongoing.

Cardiorespiratory fitness and incident lung and colon cancer: FIT-Cancer Cohort.

Catherine Handy, M.D., MPH

Cardiorespiratory fitness (CRF), an objective measure of exercise tolerance, is a strong predictor of cardiovascular disease and mortality yet its relationship with cancer incidence is unclear. In the largest study of its kind, CRF measured during exercise testing is a strong predictor of future lung and colon cancer risk. The study provides another important reason for optimizing CRF.

Nivolumab (Nivo) as neoadjuvant therapy in patients with resectable Merkel cell carcinoma (MCC) in CheckMate 358.

Suzanne Topalian, M.D., associate director of the Bloomberg~Kimmel Institute for Cancer Immunotherapy

MCC is a rare, aggressive skin cancer commonly associated with the oncogenic Merkel cell polyomavirus (MCPyV). The PD-1/PD-L1 immunosuppressive pathway is often upregulated in MCC, and advanced metastatic MCC is responsive to PD-1 blockade. This study is the first trial of anti–PD-1 in the neoadjuvant setting for resectable MCC. Nivo administered for 4 weeks before surgery in MCC was safe and induced substantial radiologic and pathologic tumor regressions in 45 percent and 65 percent of patients, respectively. In some patients, this obviated the need for more extensive surgery.

Monday, June 4 at 10 a.m./Arie Crown Theater

Durable tumor regression and overall survival (OS) in patients with advanced Merkel cell carcinoma (aMCC) receiving pembrolizumab as first-line therapy.

Paul Nghiem, M.D., Ph.D (University of Washington), Suzanne Topalian, M.D., associate director of the Bloomberg~Kimmel Institute for Cancer Immunotherapy

Merkel cell carcinoma (MCC) is an aggressive skin cancer often caused by the Merkel cell polyomavirus (MCPyV). Clinical trials of PD-1-axis blocking agents in aMCC have demonstrated increased progression free survival (PFS) compared to historical data from patients (pts) receiving chemotherapy, but data on response durability and OS are limited. Here we report outcomes from the expanded phase 2 Cancer Immunotherapy Trials Network-09 trial of pembrolizumab (PEM, anti-PD-1) in the first-line setting (NCT02267603).
