About this study
Official title: Phase I/II and Pharmacological Study of Intravenous OTS167 in Patients With Refractory or Relapsed Acute Myeloid Leukemia, Acute Lymphoblastic Leukemia, Advanced Myelodysplastic Syndromes, Advanced Myeloproliferative Neoplastic Disorders, or Advanced Chronic Myelogenous Leukemia
The purpose of Phase I of this study is to test the safety and tolerability of the investigational drug, OTS167, and that of Phase II of this study is to confirm the potential response benefit of OTS167.
OTS167 is a maternal embryonic leucine zipper kinase (MELK) inhibitor which demonstrated antitumor properties in laboratory tests. It is being developed as an anti-cancer drug. In this study OTS167 will be administrated to patients with AML, ALL, advanced MDSs, advanced MPNs, or advanced CML.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing OTS167IV in people with AML and Advanced MDS, run by OncoTherapy Science, Inc. at 2 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 17 inclusion and 8 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 24 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 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 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?
The study was stopped early (reason given: slow patient accrual). 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?
Adverse events assessed by CTCAE v4.03 (time frame: Up to 30 days after last dose of study drug). 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 24 Nov 2021; AzTrials last refreshed its copy on 8 Nov 2026.
