A Study of Avelumab in Combination With Axitinib In Non-Small Cell Lung Cancer (NSCLC) or Urothelial Cancer (Javelin Medley VEGF)

Inclusion Criteria:

Non-small cell lung cancer (NSCLC) Cohort: Histologically or cytologically confirmed diagnosis of NSCLC that is locally advanced or metastatic; No activating EGFR mutations, ALK or ROS1 translocations/rearrangements where testing is standard of care; received at least 1 prior platinum-based chemotherapy regimen for locally advanced or metastatic NSCLC; No more than 2 prior lines of systemic therapy for locally advanced or metastatic disease (If disease progression occurred during or within 6 months after neoadjuvant/adjuvant chemotherapy or radiotherapy-chemotherapy, the regimen is counted as 1 prior treatment regimen towards the allowed limit of prior treatment regimens); Checkpoint inhibitor naïve.
Urothelial Cancer (UC) Cohort: Histologically or cytologically confirmed diagnosis of transitional cell carcinoma (TCC) of the urothelium (if mixed, more than 50% TCC component) including bladder, urethra, ureters, or renal pelvis that is locally advanced or metastatic; No prior systemic treatment for locally advanced or metastatic disease; Prior neoadjuvant or adjuvant therapy is permitted if disease progression occurred >12 months after the completion of therapy; Checkpoint inhibitor naïve; Ineligible for receiving cisplatin-containing front-line chemotherapy based at least one of the following criteria: ECOG performance status (PS) 2; Renal dysfunction (defined as creatinine-clearance <60 ml/min); Grade 2 peripheral neuropathy; Grade 2 hearing loss (hearing loss measured by audiometry of 25 decibels at two contiguous frequencies).
At least 1 measurable lesion by RECIST v1.1 not previously irradiated.
Availability of an archival FFPE tumor tissue block from primary diagnosis specimen or metastatic specimen or 15 unstained slides (10 minimum). If an archived sample is not available, a fresh tumor biopsy must be performed.
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. For UC patients, ECOG performance 2 is permitted (cisplatin ineligibility criterion)

Exclusion Criteria:

Prior immunotherapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, anti-OX-40, anti-GITR, anti-LAG-3, anti-TIM-3 or anti-CTLA-4 antibody (including ipilimumab).
Newly diagnosed brain metastases or known symptomatic brain metastases requiring steroids.
Radiologically documented evidence of major blood vessel invasion or encasement by cancer or intratumor cavitation, regardless of tumor histology.
Active autoimmune disease (that might deteriorate when receiving an immunostimulatory agent).
Current use of immunosuppressive medication (except for those listed in protocol).
Known prior severe hypersensitivity to the investigational products /monoclonal antibodies.
Known history of immune-mediated colitis, inflammatory bowel disease, immune-mediated pneumonitis, pulmonary fibrosis.
NCI CTCAE Grade 3 hemorrhage within 28 days prior to study enrollment.
