Trial summary

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Tretinoin may help hematologic cancer cells develop into normal white blood cells. Read more about this study

About this study

Official title: A Phase I, Dose-Finding Trial of Sodium Phenylbutrate (NSC 657802) in Combination With All Trans-retinoic Acid (ATRA, NSC 122758) in Patients With Myelodysplastic Syndromes (MDS) and Acute Myeloid Leukemia (AML)

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Tretinoin may help hematologic cancer cells develop into normal white blood cells.

PURPOSE: Phase I trial to study the effectiveness of combining phenylbutyrate and tretinoin in treating patients who have hematologic cancer.

Read the detailed description

OBJECTIVES:

  • Determine the safety and toxicity of phenylbutyrate and tretinoin in patients with myelodysplastic syndromes, chronic myelomonocytic leukemia, or acute myeloid leukemia.
  • Determine the pharmacokinetic interaction of this regimen in these patients.
  • Determine any potential therapeutic activity of this regimen in these patients.

OUTLINE: This is a dose escalation study of tretinoin.

Patients receive phenylbutyrate IV continuously on days 1-7 of weeks 1, 5, 7, 9, 11, 13, 15, 17, and 19. Patients also receive oral tretinoin three times daily on days 1-7 of weeks 3, 5, 7, 9, 11, 13, 15, 17, and 19. Treatment continues in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of tretinoin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 6 patients experience dose limiting toxicities.

An additional cohort of 6 patients is accrued at the MTD. These patients receive phenylbutyrate IV continuously on days 1-3 of weeks 1 and 3-18. These patients also receive oral tretinoin three times daily on days 1-3 of weeks 2-18. Treatment continues in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months.

PROJECTED ACCRUAL: A total of 3-24 patients will be accrued for this study within 18 months.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing sodium phenylbutyrate and tretinoin in people with Leukemia and Myelodysplastic Syndromes, run by Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins 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?

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 29 Sep 2017. 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 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.

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 29 Sep 2017; AzTrials last refreshed its copy on 8 Nov 2026.
