Critères d'inclusion : Part B:
- Availability of a fresh tumor biopsy is mandatory for eligibility in the RCC cohort. The biopsy or surgical specimen should be collected within 28 days prior to the first IMP administration. If a subject has 2 separate biopsy attempts in which usable tissue is not obtained, enrollment may be possible after discussion with the Medical Monitor. For other expansion cohorts, availability of either tumor archival material (< 6 months old) or fresh biopsies (obtained within 28 days) is acceptable with one of these being mandatory. For formalin-fixed paraffin-embedded samples, either block or sections (> 15) may be provided. Tumor biopsies and tumor archival material must be suitable for biomarker assessment
- Urothelial carcinoma (UC) post-platinum: Histologically or cytologically confirmed locally advanced or metastatic transitional cell carcinoma of the urothelium (including renal pelvis, ureters, urinary bladder, and urethra). Subjects must have progressed after treatment with at least 1 platinum containing regimen for inoperable locally advanced or metastatic UC or disease recurrence. Availability of either tumor archival material (< 6 months old)or fresh biopsies (obtained within 28 days) is acceptable with one of these being mandatory. For formalin-fixed paraffin-embedded samples, either block or sections (> 15) may be provided. Tumor biopsies and tumor archival material must be suitable for biomarker assessment.
- Non-small cell lung cancer (NSCLC), first-line metastatic: Stage IV (per seventh International Association for the Study of Lung Cancer classification) histologically confirmed NSCLC. Subjects must not have received treatment for their metastatic disease. Subjects could have received adjuvant chemotherapy or loco-regional treatment that included chemotherapy for locally advanced disease, as long as disease recurrence occurred at least 6 months after the completion of the last administration of chemotherapy. Only epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) wild-type are allowed (ie, EGFR mutation and ALK translocation / re arrangement excluded). Non squamous cell histologies and never / former light smoker (< 15 pack years) squamous cell carcinoma subjects (per local standard of care) require testing if status is unknown. Subjects must have low tumor PD-L1 expression defined as < 50% tumor proportion score determined using PD-L1 IHC 22C3 pharmDx test or an equivalent Food and Drug Administration (FDA)- approved PD-L1 test. Availability of either tumor archival material or fresh biopsies within 28 days is acceptable with one of these being mandatory. For FFPE samples, either block or sections (> 15) may be provided. Tumor biopsies and tumor archival material must be suitable for biomarker assessment. This cohort will not be opened for enrollment in Belgium, Czech Republic, France, Germany, Hungary, Italy, Netherlands, Spain, and United Kingdom.
- Colorectal cancer (CRC): Histologically or cytologically confirmed recurrent or refractory metastatic CRC (according to American Joint Committee on Cancer / International Union Against Cancer Tumor Node Metastasis [TNM] Staging System seventh edition) after failure of prior therapy containing oxaliplatin / fluoropyrimidine and / or irinotecan / fluoropyrimidine and, if eligible, cetuximab (Erbitux®) and bevacizumab (Avastin®). Only subjects with microsatellite instability (MSI)-low or microsatellite stable (MSS) metastatic CRC are eligible. Subjects without existing MSI test results will have MSI status performed locally by a Clinical Laboratory Improvement Amendments (CLIA)-certified IHC or polymerase chain reaction (PCR)-based test (PCR based MSI test is preferred). Subjects must be willing to undergo an on-treatment biopsy procedure. Availability of either tumor archival material or fresh biopsies within 28 days is acceptable with one of these being mandatory. For FFPE samples, either block or sections (> 15) may be provided. Tumor biopsies and tumor archival material must be suitable for biomarker assessment. For Belgium, Czech Republic, France, Germany, Hungary, Italy, Netherlands, Spain, and United Kingdom, subjects in the second-line setting should have exhausted or be considered ineligible or intolerant (in the opinion of the Investigator) of available second-line chemotherapy options.
- Renal cell carcinoma (RCC), primary immune checkpoint inhibitor failure: Histologically or cytologically documented metastatic RCC with a component of clear cell subtype. Subjects must have had progressive disease (PD) within 6 months or best overall response of stable disease (SD) for ≥ 6 months following start of therapy with any antibody / drug targeting T cell co-regulatory proteins (immune checkpoints) such as anti-PD-1, anti-PD-L1, or anticytotoxic T lymphocyte antigen-4 (CTLA-4) for advanced or metastatic disease (either as monotherapy or combination therapy, in any line). Fresh tumor biopsy is required for enrollment. If a subject has 2 separate biopsy attempts in which usable tissue is not obtained, enrollment may be possible after discussion with the Medical Monitor. Subjects must be willing to undergo an on-treatment biopsy procedure. In France, in addition to having received checkpoint inhibitor therapy, subjects should have already received recommended local-standard therapy per the discretion of the Investigator.
Critères de non-inclusion : - Concurrent treatment with a non-permitted drug/intervention (listed below)
Anticancer treatment (eg, cytoreductive therapy, radiotherapy, immune therapy, cytokine therapy, monoclonal antibody, targeted small molecule therapy) or any investigational drug within 4 weeks or 5 half-lives, whichever is shorter, prior to start of trial treatment, or not recovered from adverse event (AE) related to such therapies, with the following exceptions: Palliative radiotherapy delivered in a normal organ-sparing technique is permitted; Erythropoietin, darbepoetin-α and granulocyte colony-stimulating factor are permitted; Hormonal therapies acting on the hypothalamic-pituitary-gonadal axis are permitted (i.e. luteinizing hormone-releasing hormone agonist/antagonists). No other hormonal anticancer therapy is permitted.
- Major surgery (as deemed by Investigator) for any reason, except diagnostic biopsy, within 4 weeks prior to start of trial treatment, or not fully recovered from surgery within 4 weeks prior to start of trial treatment
- Subjects receiving immunosuppressive agents (such as steroids) for any reason should be tapered off these drugs before start of trial treatment, with the following exceptions: Subjects with adrenal insufficiency, may continue corticosteroids at physiologic replacement dose, equivalent to ≤ 10 mg prednisone daily; Administration of steroids through a route known to result in a minimal systemic exposure (topical, intranasal, intra-ocular, or inhalation) is permitted; Previous or ongoing administration of systemic steroids for the management of an acute allergic phenomenon is acceptable as long as it is anticipated that the administration of steroids will be completed in 14 days, or that the dose after 14 days will be equivalent to <= 10 mg prednisone daily.
