Testing HSK42360 for solid tumors with BRAF V600 mutation

A Phase I, Open-label, Dose-escalation and Expansion Study to Evaluate the Safety, Tolerability, Pharmacokinetic and Pharmacodynamic of HSK42360 in Patients With BRAF V600 Mutation Locally Advanced or Metastatic Solid Tumors

Phase 1 Interventional Haisco Pharmaceutical Group Co., Ltd. · NCT06536400

This study is testing a new oral medication called HSK42360 to see if it is safe and helpful for people with advanced solid tumors that have a specific BRAF V600 mutation.

What this trial studies

This phase I clinical trial evaluates the safety and tolerability of HSK42360, an oral medication, in patients with locally advanced or metastatic solid tumors that have a BRAF V600 mutation. The study is divided into two phases: Phase Ia focuses on dose escalation and safety evaluation, while Phase Ib involves expanding the cohort to further assess the drug's pharmacokinetics and pharmacodynamics. Patients will be enrolled based on specific eligibility criteria, including prior treatment history and performance status.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with locally advanced or metastatic solid tumors who have failed standard treatments and have a confirmed BRAF V600 mutation.

Not a fit: Patients without the BRAF V600 mutation or those with untreated brain metastases may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with BRAF V600 mutation-positive solid tumors.

How similar studies have performed: Other studies targeting BRAF V600 mutations have shown promising results, indicating potential for success with this approach.
