研究概览
简要总结
This is a Phase 1/2, open-label, multi-center, non-randomized, dose-escalation study of PT-112 in combination with the anti-PD-L1 antibody, avelumab, in selected advanced solid tumors.
The study is to be conducted in two parts: the Dose Escalation Phase of PT-112 within the combination and the Dose Confirmation Phase in patients with non-small cell lung cancer who will be treated at the RP2D.

- •Known symptomatic central nervous system (CNS) metastases requiring steroids.
- •Diagnosis of any other malignancy within 2 years prior to enrollment;

- •Current use of immunosuppressive medication at study entry;
- •Active or prior autoimmune disease that might deteriorate with receiving an immunostimulatory agent;
- •Acute or chronic infections requiring systemic therapy;
- •Known history of autoimmune colitis, inflammatory bowel disease, pneumonitis, pulmonary fibrosis;
- •Known intolerance to checkpoint inhibitor therapy, defined by the occurrence of an AE leading to drug discontinuation;
