Trial of INI-4001 in Patients With Advanced Solid Tumours

PHASE1NOT_YET_RECRUITING

Phase 1 open-label, dose-escalation and dose-expansion study of INI-4001 as a single agent and in combination with approved checkpoint inhibitors in subjects with advanced solid tumors.

Simpliy with AI

Study details:

This is a Phase Ia/Ib, open-label, dose-escalation, and dose expansion study. This study will be conducted in two parts: Phase Ia (dose escalation) and Phase Ib (dose expansion). Phase Ia will initially seek to establish the MTD of INI-4001 administered as a monotherapy.

Following identification of the MTD, any dose level at or below the MTD may be further expanded to further explore the safety, PK, PD, and preliminary efficacy of INI-4001 alone and in combination with a complementary therapy (Phase Ib). Following cessation of INI-4001, patients will be requested to participate in long-term follow-up to assess overall survival. This long-term follow-up will continue for each patient until at least 1 year after their last dose of INI-4001, or until otherwise advised by the Sponsor.
