About this study

Official title: A Phase I, Dose-finding Study of the Oral, Dual Phosphatidylinositol 3(PI3)-Kinase / Mammilian Target of Rapamycin (mTOR) Inhibitor BEZ235 in Adult Patients With Relapsed or Refractory Acute Leukemia

Primary objectives:

  • To establish the maximum tolerated dose (MTD), and the recommended Phase 2 dose (RP2D) of BEZ235 when administered twice daily (BID) as a single agent in patients with relapsed or refractory acute leukemia
  • To determine the dose-limiting toxicity (DLT)
Read more

Secondary objectives:

  • Assess the safety and tolerability of daily oral administration of BEZ235 with a BID schedule
  • To describe preliminary anti-leukemic activity of BEZ235 in patients with acute leukemia
  • To correlate changes in pharmacodynamic biomarkers with basic pharmacokinetic data

Exploratory objectives:

  • To assess pre-treatment phosphatidylinositol 3-kinase (PI3K) pathway-related genes in blast cells and all other malignant cells derived from blood or bone marrow.
  • To assess the pharmacodynamic changes in components of the PI3K-protein kinase B (AKT)-mTOR pathway in bone marrow following treatment as potential predictive biomarkers of pharmacodynamic (PD) activity of BEZ235 in association with clinical responses.
  • To identify potential resistance mechanisms and biomarkers that may correlate with efficacy and response from blood and bone marrow samples pre-and post-treatment in case of resistance

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BEZ235 in people with Acute Lymphoblastic Leukemia and Leukemia, Myelocytic, Acute, run by Goethe University at 1 site in Germany.

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 22 inclusion and 34 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: finished, as of the sponsor's last update on 16 Feb 2023. 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 Germany. 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 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.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Recommended Phase 2 dose (RP2D) of BEZ235 in acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML) and chronic myeloid leukemia in blastic phase (CML-BP) (time frame: 6 months after inclusion of first patient). 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?

On the ClinicalTrials.gov record for NCT01756118, which also lists 1 linked publication.

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 16 Feb 2023.
