Brief Summary:
This is a Phase 1b/2, open label, multicenter, safety and clinical activity study of avelumab in combination with chemotherapy as first-line treatment of adult patients with locally advanced or metastatic solid tumors. Initially, avelumab will be evaluated in combination with pemetrexed and carboplatin in patients with advanced non-squamous non-small cell lung cancer (NSCLC) (Cohort A1) and in combination with gemcitabine and cisplatin in patients with cisplatin-eligible urothelial (bladder) cancer (UC) (Cohort A2). As more information is learned about other anti-cancer immunotherapy agents, in future portions of the study, avelumab may be combined with chemotherapy and other anti-cancer immunotherapy agents in patients with these same or different tumor types.

Condition or disease Intervention/treatment Phase
Non-small Cell Lung Cancer Urothelial Cancer Drug: Avelumab 800 mg in combination with pemetrexed / carboplatin Drug: Avelumab 800 mg in combination with gemcitabine / cisplatin. Drug: Avelumab 1200 mg in combination with pemetrexed/carboplatin Drug: Avelumab 1200 mg in combination with gemcitabine/cisplatin Phase 1 Phase 2

Detailed Description:

This is a Phase 1b/2, open label, multicenter, safety, clinical activity, pharmacokinetic (PK), and pharmacodynamics (PD) study of avelumab in combination with chemotherapy with or without other anti-cancer immunotherapies, as first-line treatment of adult patients with locally advanced or metastatic solid tumors. Initially, avelumab will be evaluated in combination with pemetrexed and carboplatin in patients with advanced non-squamous non-small cell lung cancer (NSCLC) (Cohort A1) and with gemcitabine and cisplatin in patients with cisplatin-eligible urothelial cancer (UC) (Cohort A2).

Given the growing preclinical and clinical indications that combinations of anti-cancer immunotherapies potentially improve patient outcomes compared to results seen with single agents, in portions of the study to be added in the future, avelumab will be evaluated in combination with both standard-of-care chemotherapy and other anti-cancer immunotherapies in patients with advanced malignancies. Each cohort in the study will consist of a Phase 1b lead-in portion to evaluate safety and a Phase 2 cohort expansion to evaluate safety and efficacy.

In the Phase 1b safety lead-in portion, up to 12 patients will be enrolled into each cohort and evaluated for dose-limiting toxicities (DLT) during the first 2 cycles of treatment. If investigational products administration in a cohort is deemed safe in the Phase 1b lead-in, enrollment may be expanded into the Phase 2 cohort expansion. Up to approximately 40 patients in each cohort (including those enrolled in the Phase 1b lead-in and those enrolled in the Phase 2 cohort expansion) will be enrolled and treated with avelumab plus chemotherapy in the initial portion of the study and, in future portions of the study, with avelumab plus chemotherapy with or without other anti-cancer immunotherapies.

In the Phase 1b lead-in portions of NSCLC Cohort A1 and UC Cohort A2, avelumab is dosed at 800 mg fixed dose every 3 weeks. Under Protocol Amendment 4, avelumab is dosed at 1200 mg fixed dose every 3 weeks in the Phase 1b lead-in portions of NSCLC Cohort A3 and in UC Cohort A4, in combination with the same standard-of-care chemotherapy doublets used in Cohort A1 and Cohort A2, respectively. For each tumor type, the study treatment combination with the highest avelumab dose determined to be safe may be advanced into Phase 2 cohort expansion.

  7. Progression Free Survival (PFS) as Per RECIST v 1.1 by Investigator Assessment [ Time Frame: From start of treatment until disease progression or death due to any cause, whichever occurred first (maximum up to 3.5 years approximately) ]
    PFS was defined as the time from the date of first dose of study treatment to the date of the first documentation of PD per RECIST v1.1 or death due to any cause, whichever occurred first. PD = at least a 20% increase in sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm or appearance of one or more new lesions was considered progression.

    DOR was defined as time from the first documentation of objective response (confirmed CR or PR) to the date of first documentation of PD or death due to any cause, whichever occurs first. As per RECIST v1.1, CR = disappearance of target and non-target lesions, with exception of nodal disease and normalization of tumor markers. All nodes, both target and non-target must have short axis measures <10 mm. PR = at least a 30% decrease in the sum of measures (longest diameter for tumor lesions and short axis measure for nodes) of target lesions, taking as reference baseline sum of diameters. Non-target lesions must be non-PD. PD = at least a 20% increase in sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm or appearance of one or more new lesions was considered progression.

    TTR was defined as the time from the date of first dose of study treatment to the first documentation of objective response (CR or PR) as assessed by investigator according to RECIST v 1.1. As per RECIST v 1.1, CR was defined as disappearance of all target and non-target lesions, with exception of nodal disease. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

  11. Absolute Value of Tumor Mutational Burden (TMB) in Tumor Tissue [ Time Frame: Pre-dose on Day 1 of Cycle 1 ]
    Mutational load within tumor tissue was defined as number per megabase of the genome, coding, base substitution, and indel mutations present in the sample. Mutational load was determined in whole blood samples using next generation deoxyribonucleic acid (DNA) sequencing followed by computational analysis.

  12. Number of Participants With Programmed Death-Ligand 1 (PD-L1) Expression [ Time Frame: Baseline and Cycle 2 Day 8 (each cycle of 21 days) ]
    PD-L1 expression at was defined as the number of PD-L1 positive cells and/or qualitative assessment of PD-L1 staining on tumor and inflammatory cells in regions of interest. PD-L1 expression in the tumor was determined using immunohistochemistry. Participants were considered positive if their pretreatment tumor tissue sample demonstrated cell surface PD-L1 expression >=1% tumor cells or >= 5% immune cells and were otherwise considered negative. PD-L1 expression at baseline and on-treatment were reported in this outcome measure.
