About this study

Official title: Individualized Treatment for Relapsed/Refractory Acute Leukemia Based on Chemosensitivity and Genomics/Gene Expression Data

This pilot clinical trial studies the feasibility of choosing treatment based on a high throughput ex vivo drug sensitivity assay in combination with mutation analysis for patients with acute leukemia that has returned after a period of improvement (relapsed) or does not respond to treatment (refractory). A high throughput screening assay tests many different drugs individually or in combination that kill leukemia cells in tiny chambers at the same time. High throughput drug sensitivity assay and mutation analysis may help guide the choice most effective for an individual's acute leukemia.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To test patient cells in a high throughput assay against individual drugs and drug combinations within 21 days to enable optimal choice of drug combinations for therapy.

II. To test gene expression that reveals activation of druggable pathways or mutations in genes that confer susceptibility to specific agents may also be considered in choice of treatment.

SECONDARY OBJECTIVE:

  1. To evaluate the response to the chosen therapy.

OUTLINE:

Leukemia cells obtained from blood or bone marrow are analyzed for sensitivity to both individual drugs and drug combinations via high throughput chemotherapy sensitivity assay and next generation sequencing assays. Doctors will then recommend chemotherapy regimens based on the results.

After completion of the chemotherapy regimen, patients are followed up at 2-4 weeks for response, and then every 3 months for 2 years for duration of response and survival.

Being tested
Chemosensitivity Assay, Cytology Specimen Collection Procedure, Gene Expression Analysis, Genetic Variation Analysis, In Vitro Sensitivity-Directed Chemotherapy

What is being measured

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

  1. Percentage of Patients we Are Able to Test and Initiate Treatment Within a 21 Day Period

    The study will be considered successful (feasibility demonstrated) if it is possible to choose and initiate a combination drug regimen within 21 days in 9 out of 15 patients. With that outcome, there would be 90% confidence that the true feasibility rate is at least 40%.

    Measured: Up to 21 days

Secondary outcomes (2)
  1. Rate of Complete Remission

    The secondary objective is to evaluate the response to the chosen therapy. Response will be evaluated using European LeukemiaNet Response Evaluation Criteria in AML (2010 version)

    Measured: Up to 2 years

  2. Survival

    Disease free and overall survival data will be assessed by contacting the referring MD or the patient every three months for the first two years.

    Measured: Up to 2 years

Questions about this trial

What is this clinical trial studying?

A study testing Chemosensitivity Assay, Cytology Specimen Collection Procedure and Gene Expression Analysis in people with Recurrent Acute Leukemia of Ambiguous Lineage and Recurrent Acute Lymphoblastic Leukemia, run by University of Washington 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 13 inclusion and 4 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 30 Jun 2022. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 30 Jun 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percentage of Patients we Are Able to Test and Initiate Treatment Within a 21 Day Period (time frame: Up to 21 days). 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 30 Jun 2022.
