Trial of Intratumoral Injections of TTI-621 in Subjects With Relapsed and Refractory Solid Tumors and Mycosis Fungoides

Summary

This is a multicenter, open-label, phase 1 study conducted to test intratumoral injections of TTI-621 in subjects that have relapsed and refractory percutaneously accessible solid tumors or mycosis fungoides. The study will be performed in two different parts. Part 1 is the Dose Escalation phase and Part 2 is the Dose Expansion phase. The purpose of this study is to characterize the safety profile of TTI-621 and to determine the optimal dose and delivery schedule of TTI-621. In addition, the safety and antitumor activity of TTI-621 will be evaluated in combination with other anti-cancer agents or radiation.
