JMT106 Injection in the Treatment of Advanced Solid Tumors

Официальное название

A Phase I Clinical Trial to Evaluate the Safety, Tolerability, Pharmacokinetic Characteristics, Immunogenicity, and Preliminary Antitumor Activity of JMT106 Injection in Patients With Advanced Solid Tumors

Обзор

This study is the first-in-human Phase I study of JMT106 injection, comprising two phases: Dose escalation with backfill and cohort expansion. The planned study population consists of subjects with advanced solid tumors. The objective is to evaluate the safety, tolerability, pharmacokinetics and preliminary efficacy of JMT106 injection as monotherapy in participants with advanced solid tumors

Критерии исключения

• Adverse reactions from prior antitumor therapy not recovered to CTCAE 5.0 Grade ≤1 (excluding toxicities deemed non-risky by the investigator, e.g., alopecia).
• Any antitumor therapy (chemotherapy, targeted therapy, immunotherapy, etc.) or investigational intervention within 4 weeks or 5 half-lives (whichever is shorter) before the first dose, or traditional Chinese medicine with antitumor indications within 14 days prior.

• Concurrent participation in another interventional clinical trial (observational trials or follow-up phases allowed).
• Major surgery within 28 days before the first dose or planned tumor resection during the study.
• Significant bleeding tendency within 4 weeks before the first dose, or high-risk conditions (e.g., gastrointestinal hemorrhage, severe hemoptysis) per investigator judgment; hereditary bleeding disorders.
• Known severe allergy to the study drug or its excipients.
• Active bacterial, fungal, or viral infection requiring IV treatment within 14 days before randomization (prophylactic therapy allowed if no active infection symptoms); patients with viral hepatitis are allowed to receive antiviral treatment.
