Brief Summary

An open, non-randomized, multicenter, single-arm dose-escalation design, phase 1 trial to study the safety, tolerability, pharmacokinetics and efficacy of JYP0322 in patients with ROS1+ locally advanced/metastatic solid tumors .

Detailed Description

JYP0322 is an orally available inhibitor of ROS1 (coded by the gene ROS1). Molecular fusions are present in several different tumor types, including non-small cell lung cancer (NSCLC), glioma, etc. Patients with locally advanced or metastatic cancer with a detectable molecular fusion in targets of interest may be eligible for enrollment.

Phase 1 will assess safety and tolerability of JYP0322 via standard dose escalation scheme and determine the recommended Phase 2 dose. Safety and efficacy will be assessed in the dose expansion portion of the study.

Arm && Interventions

Group	Intervention	Description
50 mg qd	JYP0322 50 mg qd	Participants with ROS1 fusion-positive locally advanced or metastatic solid tumors will receive JYP0322 at a dose of 50 mg qd. This arm evaluates the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of this dose level.
100 mg qd	JYP0322 100 mg qd	Participants with ROS1 fusion-positive locally advanced or metastatic solid tumors will receive JYP0322 at a dose of 100 mg qd. This arm assesses safety, tolerability, and pharmacokinetics (PK) data for this dose level.
200 mg qd	JYP0322 200 mg qd	Participants with ROS1 fusion-positive locally advanced or metastatic solid tumors will receive JYP0322 at a dose of 200 mg qd. This arm examines the safety, pharmacokinetics (PK), and preliminary efficacy of this dose level.
100 mg bid	JYP0322 100 mg bid	Participants with ROS1 fusion-positive locally advanced or metastatic solid tumors will receive JYP0322 at a dose of 100 mg bid. The arm evaluates the safety, tolerability, and pharmacokinetics (PK) of this increased dosing frequency.
150 mg bid	JYP0322 150 mg bid	Participants with ROS1 fusion-positive locally advanced or metastatic solid tumors will receive JYP0322 at a dose of 150 mg bid. This arm aims to determine the optimal dosing for safety, pharmacokinetics (PK), and efficacy.
200 mg bid	JYP0322 200 mg bid	Participants with ROS1 fusion-positive locally advanced or metastatic solid tumors will receive JYP0322 at a dose of 200 mg bid. This arm focuses on evaluating safety, tolerability, and pharmacokinetics (PK) at this dose.
