Biological: TBio-6517|Biological: Pembrolizumab

This is a Phase 1/2a dose escalation study with TBio-6517 administered by direct injection into tumor(s) or by intravenous infusion. The Phase 1 portion has 4 arms; the first arm (Arm A) will determine the RP2D of TBio-6517 alone when directly injected into tumor(s), and the second arm (Arm B) will determine the RP2D of TBio-6517 when combined with pembrolizumab. The third and fourth arms will determine the RP2D of TBio-6517 when given intravenously alone and with pembrolizumab, respectively.

In the Phase 2a portion, the clinical benefit of TBio-6517 combined with pembrolizumab will be further explored in patients with Microsatellite Stable Colorectal Cancer (MSS-CRC), Cholangiocarcinoma (CCA), Cutaneous Melanoma, and Cutaneous Squamous Cell Carcinoma of the Skin (cSCC), as assessed by overall response rate (ORR) from central radiology review.
