About this study

Official title: A Phase 2, Open-Label, Single Arm, Multi-Center Study to Assess the Efficacy and Safety of BST-236 as a Single Agent in Adults Unfit for Intensive Chemotherapy With Relapsed or Refractory AML or Higher-Risk Myelodysplastic Syndromes

An open label multi center study to assess the safety and efficacy of BST-236 as single agent in adult patients unfit for standard therapy with Acute Myeloid Leukemia (AML) or higher-risk (HR) Myelodysplastic Syndromes (MDS) who fail to respond or relapsed following first line therapy.

Approximately 20 adult patients with relapsed and/or refractory AML and approximately 20 adult patients with relapsed and/or refractory HR MDS, will be enrolled into the study.

Patients will be treated with 1-2 induction courses and 2-4 maintenance courses. All patients will be followed for 1 year in the study and additional 1 year post study follow-up.

Being tested

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BST-236Drug

    Also called Aspacytarabine

    BST-236 is a conjugate of cytarabine and asparagine, provided as a sterile lyophilized powder for IV administration

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. CR rate

    In AML patients -The proportion of patients who achieve a CR per the IWG 2006 Criteria

    Measured: To be assessed 5 months after the last patient was enrolled to the study

  2. Overall response rate (ORR)

    In MDS patients -Overall response rate (ORR), defined as the proportion of patients who achieve a CR or PR per proposal for modification of the International Working Group (IWG) criteria for MDS, 2006

    Measured: To be assessed 5 months after the last patient was enrolled to the study

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing BST-236 in people with AML, Adult and MDS, run by BioSight Ltd. at 4 sites in United States.

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 0 inclusion and 16 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: status not confirmed, as of the sponsor's last update on 9 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. 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 phase mean?

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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

CR rate (time frame: To be assessed 5 months after the last patient was enrolled to the study). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Mar 2023.
