New antibody GEN3018 enters first human tests for tough blood cancers
NCT ID NCT07384715
First seen Jun 25, 2026 · Last updated Sep 10, 2026 · Updated 7 times
Summary
This early-stage trial is testing a new antibody drug called GEN3018 in people whose acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS) has come back or stopped responding to treatment. The main goal is to check safety and find the right dose. Up to 78 participants will receive the drug by IV, and the study will monitor them closely for side effects and any signs that the drug is working.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- GEN3018 (an antibody given by IV infusion)
- What this could lead to
- If it works, this could point toward a new treatment option for people with hard-to-treat blood cancers like AML and MDS.
- What could go wrong
- This is a very early, first-in-human trial focused on safety, not effectiveness. The drug may not work or could have serious side effects. Only 78 people will be enrolled, so results may not apply to everyone.

Key Inclusion Criteria: All Participants: * Be at least 18 years of age at the time of signing informed consent form (ICF). * Participant's life expectancy at screening is judged to be at least 3 months. * Must have fresh bone marrow samples collected at screening. * Bone marrow (BM) blasts ≥ 5% at screening. * Eastern Cooperative Oncology Group (ECOG) performance status (PS) score of ≤ 2. * Has acceptable laboratory test results during the screening period Participants with R/R AML: * Relapsed or refractory AML, either de novo or secondary, and must have failed all conventional therapies. * Relapsed or refractory to at least one prior line of therapy. Participants with R/R HR-MDS: * Diagnosed with high- or very-high risk MDS according to International Prognostic Scoring System (IPSS-R) (score of \> 4.5 ie, high or very high) or World Health Organization (WHO) 2022 classification (ie, MDS-IB1 or MDS-IB2). * Refractory or relapsed after hypomethylating agents (HMAs) (such as azacitidine or decitabine). Key Exclusion Criteria: All Participants: * Diagnosis of acute promyelocytic leukemia (APL). * Presence of extramedullary AML at screening. * Prior autologous or allogenic hematopoietic stem cell transplant (HSCT) within 3 months prior to initiation of trial treatment. * Active graft-versus-host disease. * History of severe immune-related adverse events. * Treatment with anti-cancer agent (eg, small molecule, antibody, chemotherapy, radiation therapy), or major surgery within 2 weeks prior to the first dose of GEN3018. Other protocol-defined Inclusion and Exclusion criteria may apply.
