The Phase 1/1b study consist of two parts: Dose Escalation and Dose Expansion. In the Dose Escalation Part, E7766 will be administered intratumorally in participants with advanced solid tumors or lymphomas to assess safety/tolerability profile of E7766 and to determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) of E7766. In the Dose Expansion Part, E7766 at RP2D will be administered to participants with melanoma, head and neck squamous cell carcinoma (HNSCC), breast cancer, colorectal cancer, and/or other tumors including lymphomas to confirm safety and assess preliminary clinical activity of E7766 as a single agent. Clinical activity will be evaluated by objective response rate (ORR), duration of response (DOR), and disease control rate (DCR) on treatment with E7766.
This is an open label, multicenter, phase 1/1b study to assess safety/tolerability and preliminary clinical activity of E7766 as a single agent administered intratumorally in participants with advanced solid tumors or lymphomas.
