About
This is a Phase 1, open-label, dose-escalation trial of avelumab [antibody targeting programmed death ligand 1 (anti PD-L1)] with consecutive parallel group expansion in participants with selected tumor indications. New recruitment is open for all active cohorts.
Active cohorts: Escalation revised dosing regimen cohort.
Closed cohorts: Non-small cell lung cancer (NSCLC, first line), NSCLC (post-platinum), metastatic breast cancer (MBC), colorectal cancer (CRC), urothelial carcinoma (secondary), mesothelioma, gastric/GEJ cancer (first line switch maintenance and second line), and ovarian cancer (secondary and platinum refractory + liposomal doxorubicin), renal cell carcinoma (second line) melanoma and head, neck squamous cell carcinoma (HNSCC), castrate-resistant prostate cancer (CRPC), adrenocortical carcinoma (ACC) urothelial carcinoma (efficacy), gastric/gastroesophageal junction (GEJ) cancer (third line), renal cell carcinoma (RCC, first line) and escalation phase .

Inclusion and exclusion criteria
Inclusion Criteria for dose escalation and expansion phase:
Inclusion Criteria for expansion phase:
Participants must have relapsed, refractory, or progressive disease following last line of treatment (with the exception of the gastric and gastroesophageal junction (GEJ) cancer cohort, which does not require progression). Availability of tumor archival material or fresh biopsies (excluding bone biopsies) is mandatory for eligibility in the expansion cohorts. For participants in the MBC cohort, the biopsy or surgical specimen must have been collected within 90 days prior to the first investigational medicinal product (IMP) administration. Specifically, the following will be required:
NSCLC post platinum doublet: Histologically or cytologically confirmed stage IIIB or stage IV NSCLC that has progressed after 1 line of platinum-containing doublet chemotherapy. Participants should have received only 1 line of platinum-containing treatment for metastatic disease (i.e., adjuvant treatment with a platinum-containing regimen is not sufficient for eligibility because not received in the context of a metastatic disease). Participants in the NSCLC cohort will only be enrolled in USA
NSCLC first line: Stage IV (per 7th International Association for the Study of Lung Cancer [IASLC] classification) or recurrent NSCLC that is histologically proven. Participants must not have received treatment for their metastatic or recurrent disease. No activating epidermal growth factor receptor (EGFR) mutation nor ALK translocation/re-arrangement
Gastric and GEJ cancer: Histologically confirmed, unresectable locally advanced or metastatic adenocarcinoma of the gastric and gastro-esophageal junction, treated with first-line chemotherapy combination with or without disease progression. Participants should have received no more than 1 line of treatment for metastatic disease. Participants should not have been treated with trastuzumab (but can be Human Epidermal growth factor Receptor 2 [HER2] positive). Participants who received any platinum containing doublet or triplet as a neoadjuvant chemotherapy strategy, but are not ultimately candidates for surgery will also be eligible, as long as they did not have progressive disease after completion of the neoadjuvant chemotherapy. In addition, participants with gastric cancer can enter in the study if their white blood cell (WBC) and lymphocyte count is as defined in the protocol
MBC: Participants must have histologically confirmed locally advanced or MBC and have tumor that is refractory to or progressive after standard of care therapy. Participants must have received no more than 3 prior lines of cytotoxic therapy for metastatic disease. Participants must have received a taxane and an anthracycline, unless contra-indicated
Secondary expansion cohorts: Metastatic colorectal cancer (mCRC), Metastatic castrate-resistant prostate cancer (mCRPC), melanoma, ovarian cancer, ACC, mesothelioma, urothelial carcinoma and renal cell carcinoma as defined in the protocol
Efficacy expansion cohorts: Gastric and GEJ cancer (third line), ovarian cancer (platinum Refractory + liposomal doxorubicin), urothelial carcinoma, and HNSCC as defined in the protocol
