About this study

Official title: A Phase Ib/IIa Single-arm, Open-label Clinical Trial to Evaluate the Safety, Pharmacokinetics, and Efficacy of BP1001 (a Liposomal Grb2 Antisense Oligonucleotide) in Combination With Dasatinib in Patients With Philadelphia Chromosome Positive (Ph+) Chronic Myelogenous Leukemia (CML) Including Chronic Phase Patients Who Have Failed Initial Tyrosine Kinase Inhibitor (TKI) Therapy, Accelerated or Blast Phase, Ph+ Acute Myeloid Leukemia (AML) or High-risk Ph+ Myelodysplastic Syndrome (MDS)

The primary objective of the Phase Ib study is to determine the dose-limiting toxicity (DLT) and maximal tolerated dose (MTD) of BP1001 in combination with dasatinib in patients with with Philadelphia Chromosome Positive (Ph+) Chronic Myelogenous Leukemia (CML) including chronic phase patients who have failed initial tyrosine kinase inhibitor (TKI) therapy, accelerated or blast phase, Ph+ Acute Myeloid Leukemia (AML) or High-risk Ph+ Myelodysplastic Syndrome (MDS). The primary objective of the Phase IIa study is to assess the efficacy of the combination of BP1001 and dasatinib in patients with Ph+ CML, Ph+AML, or high-risk Ph+ MDS.

Read the detailed description

The Grb2 gene has been mapped to the human chromosome region 17q22-qter, a region that is duplicated in leukemias and solid tumors, which may result in an increased copy number of the Grb2 gene product. As Grb2 is important for the transformation of murine hematopoietic cells, and the proliferation of human leukemia cells that express high levels of oncogenic tyrosine kinases, inhibition of Grb2 may have a significant impact on the natural history of leukemias. The study drug (BP1001) may be able to inhibit the cells from making Grb-2. Researchers hope that without this protein, the leukemia cells will die.

Researchers hope that the combination of BP1001 and Das will provide a benefit to Ph+ CML patients, including chronic phase patients who have failed initial TKI therapy, accelerated or blast phase Ph+ AML, and high-risk Ph+ MDS patients.

This is a Phase Ib/IIa, multicenter, study of BP1001 in combination with Das in participants with Ph+ CML, including chronic phase patients who have failed initial TKI therapy, accelerated or blast phase Ph+ AML, and high-risk Ph+ MDS.

This is a Phase Ib/IIa, multicenter, study of BP1001 in combination with dasatinib in participants with Ph+ CML who are in chronic phase who have failed initial TKI therapy, accelerated or blast phase, Ph+ AML or high-risk Ph+ MDS.

This trial will utilize a single arm, open label design to assess the safety profile, DLT, MTD, PK, and efficacy of BP1001 in combination with dasatinib.

The Phase Ib study employs an open-label, sequential, dose-escalation design to assess safety, tolerability and toxicity, tumor response and anti-leukemic activity.

A standard "3+3" design will be used in which successive cohorts of patients are being treated with BP1001 at the MTD (or highest tested dose [HTD] if the MTD is not defined) and 1 level below the MTD (or HTD) in combination with a fixed dose of dasatinib to characterize safety and biological effect, as well as identify the recommended Phase IIa dose.

Up to 6 evaluable participants are expected to participate in the Phase Ib part of the study and up to 40 evaluable participants are expected to participate in the Phase IIa part of the study.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing BP1001 (varying dose), BP1001 (fixed dose) and Dasatinib in people with Chronic Myelogenous Leukemia, Ph1-Positive and Acute Myeloid Leukemia, run by Bio-Path Holdings, Inc. at 1 site 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 30 inclusion and 17 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: withdrawn, as of the sponsor's last update on 28 May 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 withdrawn before enrolling participants, so there are no results.

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?

Dose Limiting Toxicity of BP1001 using non-hematologic and hematologic parameters per NCI CTCAE criteria (time frame: 240 days). The study lists 5 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 28 May 2020.
