P3.01-078 - Avelumab (MSB0010718C), an Anti-PD-L1 Antibody, Evaluated in a Phase III Trial versus Docetaxel in Patients with Relapsing NSCLC (ID 1588)

- 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 III study (NCT02395172) is an open-label, multicenter trial of avelumab compared with docetaxel in patients with non-small-cell lung cancer (NSCLC) that has progressed after treatment with a platinum-containing doublet.
Methods:
The primary objective of this head-to-head phase III study is to demonstrate superiority defined by overall survival (OS) of avelumab versus docetaxel in patients with locally advanced unresectable, metastatic, or recurrent NSCLC whose tumors express PD-L1 and whose disease has progressed following treatment with a platinum-containing doublet. Approximately 650 eligible patients (ECOG performance status 0-1 at trial entry, tumor archival material or fresh biopsy suitable for PD-L1 expression assessment, histologically confirmed NSCLC, and known-negative ALK mutation status, among other inclusion and exclusion criteria), including 522 patients with PD-L1—positive tumors, will be randomized 1:1 to receive either avelumab at a dose of 10 mg/kg as a 1h intravenous (IV) infusion Q2W or docetaxel at a starting dose of 75 mg/m2 (per label) by IV infusion Q3W. Patients will be stratified according to PD-L1 status. NSCLC histology and EGFR mutation status will be used to define 3 stratified levels for randomization: squamous cell, non-squamous cell/EGFR wildtype, and non-squamous cell/EGFR-activating mutations. Treatment will continue until disease progression, unacceptable toxicity, or any criterion for withdrawal occurs. Responses will be evaluated according to RECIST 1.1 and adjudicated by a blinded independent review committee. In addition to the primary endpoint of OS, secondary endpoints include progression-free survival, best overall response, quality of life assessments, and safety profile. Exploratory endpoints include duration of response, tumor shrinkage in target lesions per timepoint, immunogenicity, PK profile, and evaluation of molecular, cellular, and soluble markers in peripheral blood or tumor tissue that may be relevant to the mechanism of action of, or response/resistance to, avelumab. Safety profiling of trial drugs includes incidence of adverse events (AEs), serious AEs, and other assessments according to NCI-CTCAE v4.03. Patients receiving avelumab who have achieved a complete response (CR) will be treated for a minimum of 6 months and a maximum of 12 months after confirmation. In the case of relapse following a CR, treatment with avelumab may be re-initiated once at the discretion of the investigator and in the absence of treatment-related toxicity. For patients whose disease progresses with avelumab, treatment may continue past the initial determination of disease progression per RECIST 1.1 if the patient’s performance status has remained stable, other criteria are fulfilled, and the investigator’s opinion supports a possible benefit of continued treatment with avelumab. Patients treated with docetaxel may not crossover to the avelumab arm as long as the primary endpoint has not been met in the planned interim or final analyses. Enrollment in this trial began in April 2015. *Proposed INN.
