Trial summary

Acute Promyelocytic Leukaemia (APL) has been known as a type of cancer, which is of great significance to improve its eradication rate. Recent clinical trials show that ATRA plus ATO treatment regimen can result in complete response (CR) in 90-94% of patients and 5-year disease-free survival (DFS) in more than 90% of… Read more about this study

About this study

Official title: Implement Randomized, Controlled, International Multi-center Clinical Trial of Compound Realgar-Indigo Naturalis Formula Plus Retinoic Acid for Non-high-risk Acute Promyelocytic Leukaemia

Acute Promyelocytic Leukaemia (APL) has been known as a type of cancer, which is of great significance to improve its eradication rate. Recent clinical trials show that ATRA plus ATO treatment regimen can result in complete response (CR) in 90-94% of patients and 5-year disease-free survival (DFS) in more than 90% of patients. However, the ATRA plus ATO treatment regimen can achieve considerate survival rate, patients still need to receive infusion therapy in hospital. If oral arsenic can replace intravenous ATO without reduction of the efficacy, patients would not need to be administered to receive treatment, which would highly increase their quality of lives. Phase I, II Clinical trials have verified the security and efficacy of the Compound Realgar-Indigo Naturalis Formula. Compound Realgar-Indigo Naturalis Formula was approved by the China Food and Drug Administration in 2009. Investergators have done a multi-centre, randomized, controlled, non-inferiority phase 3 clinical trial in China. And the result showed that oral arsenic plus retinoic acid has an anti-leukaemic efficacy similar to the intravenous arsenic treatment. So Investigators performed an international multi-center, Randomized controlled clinical trialsto compare the efficacy of oral RIF plus ATRA with intravenous arsenic trioxide plus ATRA in patients with non-high-risk APL in different racial types.

Read the detailed description

Acute Promyelocytic Leukaemia (APL) has been known as a type of cancer, seriously endangering human health especially for young adults. It is of great significance to improve its eradication rate. Recent clinical trials show that ATRA plus ATO treatment regimen can result in complete response (CR) in 90-94% of patients and 5-year disease-free survival (DFS) in more than 90% of patients.

However, the ATRA plus ATO treatment regimen can achieve considerate survival rate, patients still need to receive infusion therapy in hospital. If oral arsenic can replace intravenous ATO without reduction of the efficacy, patients would not need to be administered to receive treatment, which would highly increase their quality of lives. The research and development of oral arsenic has therefore become a hotpoint. Professor Huang, Shilin from he 210th Hospital of PLA, according to the Prescription Theory "Jun Chen Zuo Shi", developed and designed an oral arsenic, the Compound Realgar-Indigo Naturalis Formula. Phase I, II Clinical trials have verified the security and efficacy of the Compound Realgar-Indigo Naturalis Formula. Research Team led by Professor Huang, Saijun, Shanghai Institute of Haematology (China), studied Compound Realgar-Indigo Naturalis Formula's mechanism of action from vitro cell lines and mice.

In the following Phase II clinical trial, APL patients received Compound Realgar-Indigo Naturalis Formula solo treatment regime. It resulted in 96.7% of CR and high safety rate Compound Realgar-Indigo Naturalis Formula was approved by the China Food and Drug Administration in 2009. Investigators have done a multi-centre, randomized, controlled, non-inferiority phase 3 clinical trial in China. 242 newly diagnosed APL patients (with newly diagnosed WBC<50×10^9/L) were enrolled. And the result showed that oral arsenic plus retinoic acid has an anti-leukaemic efficacy similar to the intravenous arsenic treatment.

What is being measured

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

  1. 2-year Event-free Survival (EFS) rate

    treatment failure (no CR after 45-day induction therapy, or no molecular complete remission after 3-month consolidation therapy), relapse (molecular relapse, or haematological relapse); or death from any cause.

    Measured: 2 year after diagnosis

Model description
This study is a prospective, non-inferiority, randomized controlled clinical trial. The non-inferiority is concluded if the lower limit of the 95% CI for the difference in proportion of patients achieving EFS is greater than the -10% non-inferiority margin. The survival curves are estimated by using the Kaplan-Meier method and will be compared by using the log-rank test.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Compound Realgar-Indigo Naturalis Formula Plus Retinoic Acid in people with Acute Promyelocytic Leukaemia, run by Peking University People's Hospital.

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 7 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 29 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Hao Jiang, MD (13601164350, 2516735116@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

2-year Event-free Survival (EFS) rate (time frame: 2 year after diagnosis). 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 29 Nov 2019.
