Study of Escalating Doses of INA03 Administered Intravenously as Single Agent in Adult Patients With Relapse/Refractory Acute Leukemia (INA03)

February 14, 2023 updated by: Institut Paoli-Calmettes

A Phase I, First in Human, Open-label Study of Escalating Doses of INA03 Administered Intravenously as Single Agent in Adult Patients With Relapse/Refractory Acute Leukemia

This Phase 1 Study is an open-label, non-randomized, dose escalation, safety, efficacy, pharmacokinetic, and pharmacodynamic evaluation study of INA03 administered as a single agent IV infusion every 2 weeks to patients ≥18 years of age with R/R AML, MLL, or ALL.

The study will be performed in 2 parts: a Dose Titration for Day 1 study (Part 1) followed by a Dose Escalation Part (Part 2) of INA03 used as monotherapy.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: INA03
INA03 administration
Drug: INA03 administration
INA03 will be administered IV on Day 1, Day 14 of 28-day cycles. The administration of INA03 will begin at 0.02 mg/kg. Study Part I is a titration study to determine the dose for the first INA03 infusion. Patients will be enrolled in sequential cohorts of 2 patients to receive ascending starting doses of INA03, starting from the lowest starting dose (0.02 mg/kg), and followed by subsequent administrations of INA03 (D14 and beyond) at a fixed dose of 0.1 mg/kg. The starting dose will be increased every cohort of 2 patients until evidence of absence of marrow residual erythroblasts by D14 myelogram. This dose is referred to as the MEID and will be selected as the D1 dose for the study Part 2. Patient accumulation in Part I of the study will continue until no evidence of non-hematological DLT within 28 days post dosing
