First-in-human Study Aiming to Characterize the Safety, Tolerability, Pharmacokinetic and Preliminary Signs of Activity of ABD-3001 in Refractory or Relapsed AML and High Risk MDS Adult Patients

First-In-Human, Open Label, Dose Escalation Study to Evaluate Safety, PK and PD of ABD-3001 As Monotherapy in Relapsed/Refractory Acute Myeloid Leukemia or High/Very-high Risk Myelodysplastic Syndromes Patients, Ineligible for Intensive or New Generation Targeted Therapy.

Summary

This First In Human (FIH) study is a prospective, open-label, multicenter, Phase 1 study, with a dose escalation design, followed by an optimized design. It will consist in a Single Ascending Dose (SAD) part and a Multiple Ascending Dose (MAD) part.

Detailed description

This FIH study combines, in patients with primary refractory or relapsed AML patients and in patients with high risk MDS a Single Ascending Dose (SAD) part (Part A) and a Multiple Ascending Dose (MAD) part (Part B). The objective of the SAD phase is to explore a wide range of dose administered as a single and fixed 4-hours intravenous infusion in order to select a dose and a dosing frequency (determined using pharmacokinetic and pharmacodynamics parameters). The objective of the MAD is to elucidate the pharmacokinetic (PK) and pharmacodynamics (PD) of multiple doses of ABD-3001. The dose levels and dosing intervals (i.e., time between consecutive doses) will be selected as those that are predicted to be safe from the SAD. Dose levels and dosing frequency will be derived from data obtained during the SAD.

Conditions

• Acute Myeloid Leukemia, Adult
• Myelodysplastic Syndromes

Interventions

Type	Name	Description
DRUG	ABD-3001	Each patient will receive a fixed 4 hours-intravenous infusion dose of ABD-3001 once or twice a week. For SAD : The first dose of the first cohort will receive an estimated infusion dose of 18 mg/m² at Day 1. Subsequent cohorts will be given the following doses: 54 mg/m², 135 mg/m², 270 mg/m², 405 mg/m², 540 mg/m².
DRUG	ABD-3001	For MAD : Based on all data gathered during the SAD including safety, PK and preliminary efficacy data, up to three doses were selected in accordance with the Safety review Committee (SRC). A dosage optimization analysis was performed at the end of the SAD cohort 6 using population pharmacokinetic modelling to set the optimal frequency of infusion per week for each selected dose to achieve sustained exposition throughout the treatment period. Based on this analysis, the Sponsor, in agreement with the SRC, defined 3 doses regimens that will be set up in parallel, with infusion of ABD-3001 once or twice a week during 3 cycles of 28 days.
