Childhood Acute Promyelocytic LeukemiaPhase 4NCT02200978
A Study for Improving the Outcome of Childhood Acute Promyeloid Leukemia
A Phase 4 study testing ATO, RIF and ATRA in people with Childhood Acute Promyelocytic Leukemia, run by South China Children's Leukemia Group at 1 site in China.
Trial summary
Outcome of acute promyelocytic leukemia (APL) has greatly improved since the introduction of all-trans-retinoic acid (ATRA). Treatment with ATRA and anthracycline-based chemotherapy (ATRA + chemotherapy) decreases relapses of the disease as well as early hemorrhagic deaths. Read more about this study

About this study
Official title: A Multicenter and Randomized Prospective Study for Improving the Outcome of Childhood Acute Promyeloid Leukemia
Outcome of acute promyelocytic leukemia (APL) has greatly improved since the introduction of all-trans-retinoic acid (ATRA). Treatment with ATRA and anthracycline-based chemotherapy (ATRA + chemotherapy) decreases relapses of the disease as well as early hemorrhagic deaths. Nowadays patients with APL have an event-free survival (EFS) of up to 80%. However, there remains a subset of the patients in whom the disease relapses. Recently, a randomized prospective study showed that the addition of ATO to "ATRA + chemotherapy" treatment protocol had a significantly higher EFS in patients with APL than those treated with "ATRA + chemotherapy" protocol. The patients treated with "ATO + ATRA + chemotherapy" had a five years EFS of 89.2%. Moreover, a recent study showed that Indigo naturalis formula (RIF), a traditional Chinese medicine with tetraarsenic tetrasulfide (As4S4), indirubin, and tanshinone IIA as major active ingredients, yielded synergy in the treatment of a murine APL model in vivo and in the induction of APL cell differentiation in vitro . It is about 20 years since RIF was used to treat ALP in China. Clinical studies showed that this agent was effective against APL. Compared to ATO, RIF is relatively inexpensive and can be taken orally, resulting in reducing the number of hospital days and the treatment cost. However, there is no report comparing treatment outcomes of "ATO + ATRA + chemotherapy" and "RIF + ATRA + chemotherapy" protocols in children with APL so far. For this purpose, therefore, investigators are going to conduct a multicenter and randomized prospective study in children with APL.

OBJECTIVES:
- Determine the safety and efficacy of "ATO/RIF + ATRA + less intensive chemotherapy" protocol in children with acute promyelocytic leukemia (APL).
- Compare the safety，efficacy and treatment cost of "RIF + ATRA + less intensive chemotherapy" with "ATO + ATRA + less intensive chemotherapy" protocol in children with APL. Determine if ATO can be substituted by RIF.
OUTLINE: This is a multicenter and randomized prospective study.
PROJECTED ACCRUAL: A total of 162 patients will be accrued for this study.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Outcome of acute promyelocytic leukemia (APL) has greatly improved since the introduction of all-trans-retinoic acid (ATRA). Treatment with ATRA and anthracycline-based chemotherapy (ATRA + chemotherapy) decreases relapses of the disease as well as early hemorrhagic deaths. Nowadays patients with APL have an event-free survival (EFS) of up to 80%. However, there remains a subset of the patients in whom the disease relapses. Recently, a randomized prospective study showed that the addition of ATO to "ATRA + chemotherapy" treatment protocol had a significantly higher EFS in patients with APL than those treated with "ATRA + chemotherapy" protocol. The patients treated with "ATO + ATRA + chemotherapy" had a five years EFS of 89.2%. Moreover, a recent study showed that Indigo naturalis formula (RIF), a traditional Chinese medicine with tetraarsenic tetrasulfide (As4S4), indirubin, and tanshinone IIA as major active ingredients, yielded synergy in the treatment of a murine APL model in vivo and in the induction of APL cell differentiation in vitro . It is about 20 years since RIF was used to treat ALP in China. Clinical studies showed that this agent was effective against APL. Compared to ATO, RIF is relatively inexpensive and can be taken orally, resulting in reducing the number of hospital days and the treatment cost. However, there is no report comparing treatment outcomes of "ATO + ATRA + chemotherapy" and "RIF + ATRA + chemotherapy" protocols in children with APL so far. For this purpose, therefore, investigators are going to conduct a multicenter and randomized prospective study in children with APL.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing ATO, RIF and ATRA in people with Childhood Acute Promyelocytic Leukemia, run by South China Children's Leukemia Group at 1 site in China.
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 1 inclusion and 1 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 10 May 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 China. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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.
What does the primary outcome measure?
event-free survival (time frame: 5 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02200978, which also lists 7 linked publications.
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 10 May 2022; AzTrials last refreshed its copy on 8 Nov 2026.
