    Lisaftoclax for Prevention of Differentiation Syndrom

    Drug: Lisaftoclax (APG-2575)

Interventions

  • DrugLisaftoclax (APG-2575)

    Description: Newly diagnosed APL patients receive standard induction therapy with oral ATRA 25 mg/m²/day and intravenous ATO 0.16 mg/kg/day. Lisaftoclax (APG-2575) is given for DS prophylaxis in patients with peripheral WBC count \>2.0×10⁹/L or ≥24-hour 2-fold WBC elevation. Lisaftoclax can only be initiated 24 hours after ATRA/ATO induction initiation. Dosing and Escalation: Lisaftoclax starts at 50 mg QD. Dose may be escalated to 100 mg QD, with a maximum dose of 100 mg twice daily (bid) based on patient tolerability. Monitoring and Interruption: Daily peripheral blood count monitoring is required during Lisaftoclax treatment. Lisaftoclax must be immediately withheld if the WBC count declines for two consecutive days. Protocol-defined dexamethasone or ruxolitinib will be administered for suspected DS during induction therapy.

What researchers measure

Primary outcomes

  1. the rate of Differentiation Syndrom

    DS, known as retinoic acid syndrome, is a severe complication of ATRA or ATO during the differentiation of promyelocytes. Signs of DS are presented as fever, weight gain, hypertension, dyspnoea, radiographic opacities, peripheral edema and acute renal failure.

    Time frame: the induction regimen (21 days to 28 days)
