Open-Label Study to Evaluate the Safety, Tolerability, PK, and Efficacy of INX-315 in Patients With Advanced Cancer

• Status: Not yet recruiting
• Trial end date: 2026-06-01

Summary

Incyclix Bio (Incyclix) is developing INX-315 as an oral, small molecule inhibitor of cyclin dependent kinase 2 (CDK2) for the treatment of human cancers. This first-in-human study is designed to evaluate the safety, tolerability, pharmacokinetics (PK) and preliminary antitumor activity of INX-315 in patients with recurrent advanced/metastatic cancer, including hormone receptor positive (HR+)/Human Epidermal Growth Factor Receptor 2 Negative (HER2-) breast cancer who progressed on a prior cyclin-dependent kinase 4/6 inhibitor (CDK4/6i) regimen, and CCNE1-amplified solid tumors who progressed on standard of care treatment. This study will evaluate approximately 6 dose levels of daily INX-315 in Part A, at least two dose levels will be evaluated in Part B to identify the Recommended Phase 2 Dose (RP2D) in patients with ovarian cancer, and Part C will evaluate combination treatment of INX-315 plus a CDK4/6i and selective estrogen receptor degrader (SERD) in HR+/HER2- breast cancer patients who have progressed on prior CDK4/6i regimen.
