Evaluating ABD-3001 for patients with difficult-to-treat blood cancers

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.

Phase1; Phase2 Interventional Advanced BioDesign · NCT05601726

This study is testing a new treatment called ABD-3001 to see if it can help adults with hard-to-treat blood cancers like Acute Myeloid Leukemia and high-risk Myelodysplastic Syndromes feel better and stay safe during the process.

What this trial studies

This first-in-human study investigates the safety, tolerability, and preliminary effectiveness of ABD-3001 in adults with refractory or relapsed Acute Myeloid Leukemia (AML) and high-risk Myelodysplastic Syndromes (MDS). The study employs a dose escalation design, consisting of a Single Ascending Dose (SAD) phase to determine the optimal dosing and a Multiple Ascending Dose (MAD) phase to further assess pharmacokinetics and pharmacodynamics. Participants will receive ABD-3001 via intravenous infusion, with careful monitoring of their response and safety throughout the trial.

Who should consider this trial

Good fit: Ideal candidates include adults with relapsed or refractory AML or high-risk MDS who are not eligible for salvage treatments.

Not a fit: Patients with specific karyotype abnormalities in AML or those with active central nervous system leukemia may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with limited alternatives for refractory AML and high-risk MDS.

How similar studies have performed: While this approach is novel for ABD-3001, similar studies targeting refractory blood cancers have shown promising results in the past.
