What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study tested a new drug called S65487, which blocks a protein that helps leukemia cells survive, combined with the standard drug azacitidine. The trial included 57 adults with untreated acute myeloid leukemia who were not healthy enough for intensive chemotherapy. Researchers aimed to find the safest dose and see if the combination could lead to complete remission.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
S65487 (a Bcl2 inhibitor) combined with azacitidine
What this could lead to
If successful, this combination could offer a new treatment option for older or frail adults with acute myeloid leukemia who cannot tolerate intensive chemotherapy.
What could go wrong
This is an early-phase trial with only 57 participants, so results may not apply to all patients. The drug combination may cause side effects or fail to improve remission rates.

Inclusion Criteria: * Male or female participant aged ≥ 18 years old * Participants with cytologically confirmed and documented treatment naïve, de novo or secondary AML defined by WHO 2016 classification (Arber, 2016). Secondary AML includes: * Previous myelodysplastic syndrome transformed * AML due to exposure to potentially leukemogenic therapies or agents (e.g. radiation therapy, alkylating agents, topoisomerase II inhibitors) with the primary malignancy in remission for at least 3 years * Participants not eligible for standard induction chemotherapy * Aged ≥ 75 years old * Or Age ≥18 years with at least one of the following comorbidities: * Clinically significant heart or lung comorbidities, as reflected by at least one of: * Lung diffusing capacity for carbon monoxide (DLCO) ≤65% of expected * Forced expiratory volume in 1 second (FEV1) ≤65% of expected * Other contraindication(s) to anthracycline therapy (must be documented) * Other comorbidity that the Investigator judges as incompatible with intensive remission induction chemotherapy, which must be documented * ECOG (Eastern Cooperative Oncology Group) performance status should be (criterion should be rechecked at inclusion visit) ECOG ≤ 2. * Written informed consent obtained prior any study-specific procedure as described in section 13.3 of the protocol. * Adequate renal and hepatic function * Circulating White Blood Cell Count (WBC count) \< 25\*109 G/L (with or without use of hydroxycarbamide/leukapheresis) * Serum potassium, serum calcium, serum phosphates, serum magnesium within normal limits with or without supplementation. Exclusion Criteria: * Major surgery within 3 weeks prior to the first IMP administration, or participants who have not recovered from side effects of the surgery * Any radiotherapy within 3 weeks before the first IMP administration, * Allogenic stem cell transplant within 3 months before the first IMP administration and/or participants with active Graft-versus-host disease within 3 months before the first IMP administration and/or participants who still receive immunosuppressive treatment within 3 months before the first IMP administration and/or participant who receive donor lymphocyte infusion (DLI) within 3 months before the first IMP administration * Acute promyelocytic leukemia (APL, French-American-British M3 classification) * Favorable risk cytogenetics such as t(8;21), inv(16) or t(16;16) or t(15;17) as per the National Comprehensive Cancer Network (NCCN) Guidelines Version 3, 2019 for Acute Myeloid Leukemia * Treatment with hypomethylating agents (decitabine/azacitidine) or Venetoclax for AHD (antecedent hematologic disorders) in the 3 months prior to the first IMP intake
