P3.01-084 - Avelumab (MSB0010718C), an Anti-PD-L1 Antibody, Evaluated in a Phase Ib Trial as a First-Line Treatment for Patients with Metastatic NSCLC (ID 1707)

- Abstract
Background:
The programmed death-1 receptor (PD-1) and its ligand (PD-L1) are key therapeutic targets in the reactivation of the immune response against multiple cancers. Avelumab* (MSB0010718C) is a fully human anti-PD-L1 IgG1 antibody currently being investigated in clinical trials. The phase Ib study (NCT01772004) is an open-label, parallel group expansion trial in patients with metastatic or locally advanced solid tumors that includes a cohort of patients with non-small-cell lung cancer (NSCLC) who have not been previously treated for metastatic or recurrent disease. Prior to adding this first-line cohort, this study had enrolled a separate cohort of patients with NSCLC who had received a prior platinum-containing doublet regimen.
Methods:
This trial cohort is enrolling patients with histologically confirmed stage IV (according to IASLC) or recurrent NSCLC who have not previously received treatment for metastatic or recurrent disease. In addition, this cohort is restricted to patients without an activating EGFR mutation or ALK rearrangement. Patients with unknown EGFR or ALK status will be tested during screening and are required to have negative status for inclusion. Eligible patients also must have tumor archival material or fresh biopsy, an ECOG performance status of 0 or 1 at the time of trial entry, and disease with at least 1 measurable lesion according to RECIST 1.1. Exclusion criteria include prior therapy with immune checkpoint drugs or a known history of autoimmune disease. Up to 150 eligible patients will receive avelumab at 10 mg/kg as an infusion Q2W. Treatment will continue until disease progression, unacceptable toxicity, or any criterion for withdrawal occurs. Treatment may be continued despite progression according to RECIST 1.1 if the patient’s clinical status is stable and, according to investigator opinion, there is no need to start salvage therapy. The primary objective of the trial is to assess the safety and tolerability of avelumab as a first-line therapy. Select secondary objectives include: assessment of best overall response (BOR) and progression-free survival (PFS) according to RECIST 1.1; assessment of immune-related BOR and immune-related PFS (using modified Immune-Related Response Criteria); and assessment of overall survival. Association between tumor PD-L1 expression and efficacy will be evaluated. Immunomonitoring of cellular and soluble markers and intratumoral cellular surveillance will also be carried out. At each visit during the treatment phase, adverse events will be assessed and graded according to NCI-CTCAE v4.0. Tumor evaluation will be performed every 6 weeks until progression. Enrollment in this cohort began in March 2015. *Proposed INN.
