Inclusion Criteria

Dose escalation (Part 1A and Part 1B):, -Patients with histologically
confirmed, advanced unresectable or metastatic solid tumor whom in the opinion
of the Investigator does not have a suitable alternative therapy.,

Dose expansion (Part 2A):, -Patients with histologically confirmed, advanced
unresectable melanoma whom in the opinion of the Investigator does not have a
suitable alternative therapy

-Patients must have failed any prior therapy based on anti-PD-1 or anti-PD-L1
as defined by disease progression within 26 weeks of initiating anti-PD-1 or
anti-PDL-1-based therapy without any evidence of a response.

-Patients must have a site of disease amenable to biopsy and be a candidate for
tumor biopsy.

-Patients must be able and willing to provide mandatory tumor biopsies prior to
and during study treatment.,

Dose expansion (Part 2B):, -Patients with avanced unresectable or metastatic
melanoma who failed after one prior therapy based on anti-PD-1 or anti-PD-L1 or
colorectal adenocarcinoma with mesenchymal molecular subtype or urothelial
cancer and have failed platinum-containing chemotherapy or non-small cell lung
cancer (NSCLC) after failure of anti-PD-1 or anti PD-L1, or hepatocellular
carcinoma (HCC) after failure of anti-PD-1 or anti PD-L1, with or without
bevacizumab.

For all indications patients must not have a suitable alternative approved
standard therapy available in the opinion of the investigator or must be
refused by the patient., Dose expansion parts 2A and 2B:, -At least 1
measurable lesion by RECIST v1.1.
