      Background:
      Lung-MAP (S1400) is a master umbrella protocol designed to establish genomic screening for previously treated squamous cell lung cancer patients (SqCCA), and independently evaluate targeted therapies with matching biomarkers and alternative therapies (designated non-match therapy) in patients without putative markers. The protocol opened June 16, 2014 with four biomarker-driven sub-studies and one non-match sub-study.

      Method:
      Eligibility stipulated advanced SqCCA, progressing after at least one prior platinum-based chemotherapy, PS 0–2, and EGFR/ALK wild-type. Tumor samples were required and analyzed for gene alterations by FoundationOne NGS assay (Foundation Medicine). The original biomarker and non-match studies were: S1400B evaluating taselisib for PI3K mutations, S1400C evaluating palbociclib for cell cycle gene alterations (CCGA), S1400D evaluating AZD4547 for FGFR mutations, S1400E evaluating rilotumumab and erlotinib for c-MET positive tumors, and S1400A evaluating durvalumab in patients with no matching biomarkers. The original design included randomization to a control arm, but was amended to a single-arm phase 2 design. The primary endpoint for each modified sub-study was response.

      Result:
      As of June 16, 2017 all original sub-studies have been closed to accrual; 1298 patients registered to the screening component of the trial and 486 patients have registered to a sub-study. Two new sub-studies have been launched and are currently accruing. Details of the completed sub-studies are included in the table.

      Conclusion:
      Lung-MAP as a master genomic screening protocol has demonstrated feasibility with respect to accrual and evaluation of targeted therapies in lower prevalence patient populations. This dynamic, centralized, single-IRB platform is well positioned to efficiently assess multiple novel therapeutics for advanced SqCCA patients.
