A Study of SHY-ONC6, a Novel Proteasome Inhibitor, in Adults With Advanced or Metastatic Solid Tumors

Официальное название

A Phase 1 Multicenter, Open-label Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of SHY-ONC6 in Participants With Advanced or Metastatic Solid Tumors

Обзор

This is a Phase 1, first-in-human (FIH), open-label, multicenter study designed to evaluate the safety, tolerability, PK, and preliminary anti-tumor activity of SHY-ONC6 in participants with advanced or metastatic solid tumors who have progressed on or are intolerant to standard therapies. The study will consist of 2 parts: a dose escalation part (Phase 1a) and a dose expansion part (Phase 1b).

Вмешательства

• Препарат SHY-ONC6
  Participants receive SHY-ONC6 administered orally once daily in 21-day cycles. SHY-ONC6 will be administered until the participant withdraws from study, experiences unacceptable toxicity or other safety event, or their disease progresses.

• Incidence of Adverse Events (AEs) and Serious Adverse Events (SAEs) (Phase 1b) [Срок оценки: From first dose through end of treatment plus a 30-day safety follow-up period.]
• Anti-Tumor Activity - Objective Response Rate [Срок оценки: Baseline through study completion, an average of 18 months.]
• Anti-Tumor Activity - Best Overall Response (BOR) [Срок оценки: Baseline through study completion, an average of 18 months.]
• Anti-Tumor Activity - Time to Response (TTR) [Срок оценки: From baseline until first documented response, assessed up to an estimated 18 months.]
• Anti-Tumor Activity - Duration of Response (DOR) [Срок оценки: Baseline through study completion, an average of 18 months.]
