A Phase 1 Open-label, Multicenter Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Anti-tumor Activity of CLN-418 in Subjects With Advanced Solid Tumors

Description

Brief Summary
Study to evaluate the safety and tolerability of the study drug CLN-418, to determine the maximum tolerated dose and/or recommended Phase 2 study dose of CLN-418.


Detailed Description
This is a study to evaluate the safety and tolerability of the study drug CLN-418, and to determine the maximum tolerated dose and/or recommended Phase 2 study dose of CLN-418. The study will also look at the anti-tumor activity, pharmacokinetics and immunogenicity of CLN-418.The study consists of 2 parts. In Part 1, patients are enrolled into different cohort doses in order to identify the appropriate recommended phase 2 dose (RP2D) or maximum tolerated dose (MTD). In Part 2, participants with metastatic / unresectable Non small cell lung cancer (NSCLC), Triple Negative Breast Cancer (TNBC) will receive the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) established in Part 1 of the study. In Part 1 and Part 2, participants will be administered treatment every 3 weeks.
