Trial summary

The purpose of this study is to find what effects, good and/or bad, treatment with two drugs has on leukemia. The first medicine is tretinoin (also called all-trans retinoic acid, ATRA, or Vesanoid). It is an approved medicine that causes the leukemia cells in APL to mature. It is related to vitamin A. Read more about this study

About this study

Official title: Phase II Study of Combined Tretinoin and Arsenic Trioxide for Patients With Newly Diagnosed Acute Promyelocytic Leukemia Followed by Risk-Adapted Postremission Therapy

The purpose of this study is to find what effects, good and/or bad, treatment with two drugs has on leukemia. The first medicine is tretinoin (also called all-trans retinoic acid, ATRA, or Vesanoid). It is an approved medicine that causes the leukemia cells in APL to mature. It is related to vitamin A. The second is arsenic trioxide (Trisenox). It is an approved medicine for APL that comes back after earlier treatment.

APL is most often treated with tretinoin and standard chemotherapy drugs. These chemotherapy drugs can cause infection and bleeding. They can also damage the heart and normal bone marrow cells. This can lead to a second leukemia years later.

In this study, the investigators are using tretinoin and arsenic trioxide together. Both drugs work to treat APL. They have been used together in only a limited number of people. The investigators want to use these drugs together to reduce the amount of standard chemotherapy and decrease side effects. The patient will receive standard chemotherapy with a drug called idarubicin only if they have a higher chance of the leukemia coming back or a higher risk of side effects.

Read the detailed description

Induction will consist of tretinoin 45 mg/m2 po daily (rounded up to the nearest 10mg) in two divided doses (25 mg/m2 in patients <20 years of age) for 35 days and ATO 0.15 mg/kg IV daily for 35 doses given 5-7 days per week. The drugs will then be discontinued, and the patient will be followed until a clinical complete remission is achieved. Idarubicin 12 mg/m2 IV for 4 doses will be added during induction on day 2 if the presenting WBC is >10,000/μl, or if the WBC increases to 5,000/μl on day 5, 10,000/μl on day 10, or 15,000/μl on day 15, because of the increased risk of the APL differentiation syndrome and relapse in these patients. Dexamethasone 10 mg twice daily with be given on days 1-14 of induction as prophylaxis for the APL differentiation syndrome. All patients will then receive four courses of consolidation with tretinoin 45 mg/m2 po daily (rounded up to the nearest 10mg) (25 mg/m2 in patients <20 years of age) for 15 days and ATO 0.15 mg/kg IV for 25 doses.

Patients with high-risk disease or who received Idarubicin during Induction may receive intrathecal cytarabine as CNS prophylaxis given by the treating physician during consolidation, at the discretion of the site PI. High-risk patients will also receive maintenance therapy with additional courses of tretinoin and ATO every 3 months for 2 years. Each maintenance course will consist of tretinoin 45 mg/m2 po daily (25 mg/m2 in patients <20 years of age) for 15 days and ATO 0.15 mg/kg IV for 10 doses. Disease status will be monitored with serial analyses of peripheral blood samples using RT-PCR for PML-RARα mRNA. Patients will be followed until relapse, death, loss to follow-up, or removal from study.

Induction therapy can be given as an inpatient or outpatient. Consolidation and maintenance treatments will be given as an outpatient. Consolidation may also be given at the patient's local institution. Intrathecal cytarabine treatments will be administered as an outpatient.

What is being measured

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

  1. To Determine the Rate of Molecular Remission

    after induction with combined tretinoin and ATO (along with idarubicin in patients with high-risk disease or who develop leukocytosis) in APL.

    Measured: 4 years

Secondary outcomes (6)
  1. Participants Who Experienced a Complete Remission

    after induction with tretinoin and ATO (with idarubicin in patients with high-risk disease or who develop leukocytosis).

    Measured: 4 years

  2. To Determine the Proportion of Patients in Molecular Remission

    after each course of postremission therapy.

    Measured: 4 years

  3. To Determine the Disease-free and Event-free Survival of Patients

    treated with this program.

    Measured: 4 years

  4. To Determine the Toxicity of This Treatment Program

    including the early death rate (within 30 days), the incidence of APL differentiation syndrome, the number and length of hospitalizations, the incidence of secondary myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML), and the effects of treatment on left ventricular ejection fraction (LVEF) Frequencies of toxicities based on the NCI Common Terminology Criteria for Adverse Events (CTCAE), version 4.0 will be tabulated.

    Measured: 4 years

  5. To Characterize the Differentiation of APL Cells During Treatment

    with combined tretinoin and ATO using serial immunophenotyping studies of peripheral blood

    Measured: 4 years

  6. Explore the in Vivo Induction of Telomerase-dependent Cell Death

    by ATRA (Tretinoin) and ATO (Arsenic Trioxide). Bone marrow samples will be analyzed at baseline and at the time of clinical CR for telomerase activity, telomere length and TERT expression

    Measured: 4 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tretinoin and Arsenic Trioxide in people with Acute Promyelocytic Leukemia, run by Memorial Sloan Kettering Cancer Center at 12 sites in 2 countries.

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 10 inclusion and 6 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 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 12 sites in United States, Canada. 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?

Yes. Results are posted in the registry (first posted 30 Nov 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?

To Determine the Rate of Molecular Remission (time frame: 4 years). 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 Nov 2021.
