About this study
Official title: A Phase Ib/II, Open Label Study of Sabatolimab as a Treatment for Patients With Acute Myeloid Leukemia and Presence of Measurable Residual Disease After Allogeneic Stem Cell Transplantation
The primary purpose of this study was to test the hypothesis that preemptive treatment with sabatolimab, alone or in combination with azacitidine, when administered to participants with Acute myeloid leukemia (AML)/secondary AML who were in complete remission with positive measurable residual disease post-allogeneic hematopoietic stem cell transplantation (Minimal residual disease (MRD)+ post- Allogeneic hematopoietic stem cell transplantation (aHSCT)), could enhance the graft versus leukemia (GvL) response and prevent or delay hematologic relapse without an unacceptable level of treatment-emergent toxicities, including clinically significant acute and/or chronic graft-versus-host disease (GvHD) and immune-related adverse events
Read the detailed description
This is a phase Ib/II, open label, multi-center study of sabatolimab as monotherapy and in combination with azacitidine, in participants with AML/secondary AML who had received one aHSCT and achieved complete remission but MRD+, by local assessment, anytime at >= Day 60 after aHSCT and at least 2 weeks after immunosuppressive medications had been tapered off.
The study was planned to enroll approximately 59 participants and be conducted in two parts:
Part 1 was a Safety Run-in of approximately 20 participants, to assess whether sabatolimab as monotherapy at the two tested dose levels (400 mg and 800 mg intravenously Q4W) was safe when administered in the post-aHSCT setting. For each dose level, once the required number of evaluable participants had been confirmed, enrollment would be halted until participants had completed the dose limiting toxicities (DLT) observation period (≥ 8 weeks following the first dose). Following the observation period for DLTs, a Safety Review Meeting was to be conducted after each dose level to assess safety and determine the recommended dose for expansion to proceed with enrollment of additional cohorts in Part 2 of the study.
Part 2 consisted of sabatolimab monotherapy expansion cohort of approximately 13 participants, sabatolimab in combination with azacitidine cohort of approximately 20 participants, and an adolescent cohort of approximately 6 participants (≥ 12 years but < 18 years of age) with sabatolimab as monotherapy. Sabatolimab was to be administered at the recommended dose for expansion determined in Part 1.
After initiating Part 2, Novartis took the decision to put enrollment in permanent halt and terminate the sabatolimab program. This decision was not driven by any safety concerns.

A dose-limiting toxicity (DLT) is defined as an adverse event or abnormal laboratory value considered by the Investigator to be at least possibly related to sabatolimab as a single contributor that occurs during the DLT observation period and meets the severity criteria as per protocol.
Measured: From Cycle 1 Day 1 to end of Cycle 2; Cycle =28 Days
Secondary outcomes (7)
Incidence of Grade III or IV Acute Graft Versus Host Disease (aGvHD)
Assessment of the treatment emergent grade III or IV aGvHD. Acute GvHD: Grade IV acute GvHD, Stage ≥3 lower GI acute GvHD (consistent with Grade III acute GvHD) or Stage ≥3 liver acute GvHD (consistent with Grade III GvHD).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The primary purpose of this study was to test the hypothesis that preemptive treatment with sabatolimab, alone or in combination with azacitidine, when administered to participants with Acute myeloid leukemia (AML)/secondary AML who were in complete remission with positive measurable residual disease post-allogeneic hematopoietic stem cell transplantation (Minimal residual disease (MRD)+ post- Allogeneic hematopoietic stem cell transplantation (aHSCT)), could enhance the graft versus leukemia (GvL) response and prevent or delay hematologic relapse without an unacceptable level of treatment-emergent toxicities, including clinically significant acute and/or chronic graft-versus-host disease (GvHD) and immune-related adverse events

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Sabatolimab and Azacitidine in people with Acute Myeloid Leukemia, run by Novartis Pharmaceuticals at 9 sites in 4 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 16 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites in Italy, Germany, France, Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 3 Jun 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
