What this trial studies

This Phase I clinical trial evaluates the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of JMKX000197 injection in patients suffering from malignant pleural effusion. The study aims to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) while exploring dose-limiting toxicities (DLT). It involves multiple centers and includes comprehensive assessments of the drug's metabolic transformation and its effects on patients' conditions.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 75 with confirmed malignant pleural effusion requiring drainage and a Karnofsky score of 60 or higher.

Not a fit: Patients with mild pleural effusion or those with a Karnofsky score below 60 may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with malignant pleural effusion, potentially improving their quality of life and survival.

How similar studies have performed: While this approach is novel, similar studies targeting malignant pleural effusion have shown promise in evaluating new treatments.
