Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Low-dose Cytarabine Plus Arsenic Trioxide | Cycle 1. 10 mg/m\^2 cytarabine was administered subcutaneously (sc) twice daily (bid) on days 1-14. 0.25 mg/kg arsenic trioxide was administered intravenously (iv) on days 1-5 and days 8-12. Cycle 2. A second identical cycle of cytarabine and arsenic trioxide was given to patients with persistent disease identified from a bone marrow sample taken on day 21 of cycle 1. Patients who achieved complete remission (CR), complete remission with incomplete platelet count recovery (CRp), or partial remission (PR) after 1 or 2 cycles received a 14-day consolidation cycle of cytarabine and arsenic trioxide with the doses and schedule identical to the initial cycle. A recovery period of up to 4 weeks between the attainment of CR, CRp, or PR and the initiation of consolidation treatment was allowed. Patients who completed consolidation treatment started maintenance treatment of arsenic trioxide 0.25 mg/kg iv on days 1 and 4 and cytarabine 10 mg/m\^2 sc bid on days 1 through 7 of a 28-day cycle. | 33 | 33 | OG000 |
| Group 2 | Low-dose Cytarabine Alone | Cytarabine was administered at a dose of 10 mg/m\^2 sc bid from days 1-14 of cycle 1. A second identical cycle of cytarabine treatment was given to patients with persistent disease identified from a bone marrow sample taken on day 21 of cycle 1. Patients who achieved a complete remission (CR), complete remission with incomplete platelet count recovery (CRp), or partial remission (PR) after 1 or 2 cycles received a 14-day consolidation cycle of cytarabine with the doses and schedule identical to the initial treatment cycle. A recovery period of up to 4 weeks between the attainment of CR, CRp, or PR and the initiation of consolidation treatment was allowed. Patients who completed consolidation treatment started maintenance treatment of cytarabine at 10 mg/m\^2 sc bid on days 1-7 of a 28-day cycle. Patients started maintenance treatment within 42 days after platelet count recovery. Maintenance treatment continued for 2 years or until unacceptable toxicity or disease progression. | 34 | 34 | OG001 |

Outcome
- Type
- SECONDARY
- Title
- Number of Participants Who Died or Were Censored by 24 Months
- Description
This measure (time to death or censor) was defined for all enrolled subjects from the date of randomization until death from any cause. If a subject was not known to have died by the end of the followup period, observation of overall survival was censored on the date the patient was last known to be alive. The number of participants who died or were censored is presented here. (Note: all subjects participating in this study had either died or were censored by 24 months.)
