Evaluate the Efficacy and Safety of Interferon-α Combined With ATO in the Treatment of Arsenic-resistant APL (APL)

June 6, 2024 updated by: Zhejiang Provincial People's Hospital

A Study to Explore the Efficacy and Safety of Interferon-α Combined With ATO and Venetoclax in the Treatment of Arsenic-resistant Acute Promyelocytic Leukemia

This study was a single-arm, open study. After the screening period, arsenic-resistant APL patients were treated with interferon α-2b, arsenic and venetoclax. The efficacy (ORR) and safety were evaluated.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Eligible APL patients with arsenic-resistant relapse will enter the run-in period, and the subjects in the run-in phase will be treated with arsenic combined with venetoclax. After the run-in period, the patients were treated with interferon α-2b, arsenic trioxide for injection and venetoclax until the outcome of CR/PR/PD/ death/withdrawal/loss to follow-up occurred. Tumor assessments were performed every 4 to 6 weeks (as determined by the investigator) during trial treatment. Those who achieved CR/PR/PD/ withdrawal were then returned to standard treatment (treatment regimen was determined by the clinician), and those who completed the combination treatment period of the trial entered the survival follow-up period.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Inclusion Criteria:

  • 1. Must sign an informed consent form (ICF) indicating that he or she understands the purpose of, and procedures required for, the study and is willing to participate in the study.
  • 2. Age 18-70 years old (including boundary value);
  • 3. The presence of promyelocytic leukemia-retinoic acid receptor alpha (PML-RARα) confirmed by morphological features, cytogenetic analysis, and real-time quantitative polymerase chain reaction (qPCR);
  • 4. Arsenic relapse resistant patients: patients who had relapsed (including molecular relapse) after remission with ATO in the previous treatment, and could not be relieved after standard treatment;
  • 5. Eastern Cooperative Oncology Group (ECOG) performance status score 0-2;
  • 6. The expected survival time is more than 3 months.

Exclusion Criteria:

  • 1. Allergy or contraindication to any study drug involved in the protocol;
  • 2. Physical examination, electrocardiogram, laboratory examination, vital signs and test related abnormalities are clinically significant (subject to clinician's judgment);
  • 3. Other serious conditions that may limit the patient's participation in the trial, such as severe liver or kidney disease; "Patients with advanced infection, uncontrolled diabetes mellitus, severe cardiac dysfunction (e.g., clinically significant prolongation of the QT interval, potentially fatal torsades de pointes) or a history of angina or major heart disease, autoimmune diseases (as judged by the clinician);"
  • 4. Pregnant or lactating women;
  • 5. Epilepsy and central nervous system dysfunction;
  • 6. Active hepatitis B, active hepatitis A, HIV positive;
  • 7. Participate in other clinical trials at the same time
  • 8. Any condition for which, in the opinion of the investigator, participation would not be in the best interest of the participant (eg, compromise the well-being) or that could prevent, limit, or confound the protocol-specified assessments.
