Evaluating JAB-2485 for Advanced Solid Tumors

Official title: A Phase 1/2a, Multi-Center, Open-Label Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Evidence of Antitumor Activity of JAB-2485 in Adult Patients With Advanced Solid Tumors

Run by Jacobio Pharmaceuticals Co., Ltd. · NCT05490472 · Data updated 2026-11-12

This study is testing a new drug called JAB-2485 to see if it is safe and can help adults with advanced solid tumors, like certain types of breast cancer and lung cancer, who have already tried other treatments.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults with advanced solid tumors who have not responded to or are intolerant of existing therapies.

Probably not a fit

Patients with central nervous system metastases or active infections may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to assess the safety and tolerability of JAB-2485, an Aurora A inhibitor, in adult patients with advanced solid tumors. The trial consists of a Dose Escalation phase to determine the maximum tolerated dose (MTD) and a Dose Expansion phase to evaluate the preliminary antitumor activity at the recommended Phase 2 dose (RP2D). Participants must have confirmed metastatic or locally advanced solid tumors and must have previously been treated with existing therapies. The study focuses on specific tumor types, including ER+ breast cancer, triple negative breast cancer, ARID1A mutant tumors, and small cell lung cancer.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced solid tumors who have limited treatment alternatives.

How similar studies have gone: Other studies involving Aurora A inhibitors have shown promise, indicating potential for success with this approach.
