Phase 1 Study of Intravenous KK2260 in Adults With Advanced or Metastatic Solid Tumors Including Esophageal and Head and Neck Squamous Cell Carcinoma

What this Trial Is About

Researchers are studying KK2260 in patients with advanced or metastatic solid tumors to evaluate its safety, tolerability, and effectiveness. This is a first-in-human, phase 1 clinical trial that aims to determine the maximum tolerated dose MTD and assess different dosing regimens. The study focuses on patients with various solid tumors, including esophageal squamous cell carcinoma and head and neck squamous cell carcinoma. KK2260 will be given intravenously at several dose levels. In Part 1a, the maximum tolerated dose will be identified while monitoring safety. Parts 1b and 2 will test at least two dosing regimens for different cancer types to evaluate the safety, tolerability, and efficacy of each regimen. The study is open-label, non-randomized in early parts, and randomized in the later part, with participants assigned to different dosing groups. Participants will undergo weekly laboratory tests for blood counts, liver and kidney function, and other measures for about one year. Researchers will monitor adverse events, vital signs, ECG parameters, and performance status regularly. Various outcomes such as dose-limiting toxicity, overall response rate, progression-free survival, and overall survival will be tracked during treatment and follow-up. The study includes tumor biopsies before and after treatment. The total duration of involvement may last around one year or more depending on treatment and follow-up.
