Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients with pathologically confirmed HER2-positive locally advanced or metastatic solid tumors.

Probably not a fit

Patients with uncontrolled CNS metastases, certain heart conditions, or autoimmune diseases 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 clinical trial evaluates the safety, tolerability, pharmacokinetics, and anti-tumor activity of YH32367, a bispecific antibody targeting HER2 and 4-1BB, in patients with HER2-positive locally advanced or metastatic solid tumors. The study consists of two parts: a Dose Escalation phase to determine the Maximum Tolerated Dose (MTD) and a Dose Expansion phase to confirm the safety and efficacy at the recommended dose. Participants must provide tumor tissue samples and have measurable lesions to qualify for the trial.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with HER2-positive solid tumors.

How similar studies have gone: Other studies involving bispecific antibodies targeting HER2 have shown promise, suggesting potential for success in this approach.
