NCT04088513

Brief Summary

Aspirin was reported to induce hemolysis in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency on some occasions, while still widely uesd for stroke prevention. The SAST trial is designed to evaluate the safety and efficacy of aspirin in patients this enzyme disorder.The primary purpose of the trial is to evaluate the hemolytic effects of a 3-month regimen of aspirin 100mg/d versus a 3-month regimen of clopidogrel 75mg/d.

Outcome Measures

Primary Outcomes (1)

  • Proportion of protocol-defined hemolysis.

    Protocol-defined hemolysis is defined as one or more of the following conditions: a) Hemoglobin level declined ≥2.5 g/dL from baseline, meanwhile ruling out bleeding events. b) Hemoglobin level declined ≥25% from baseline, meanwhile ruling out bleeding events. c) Clinically relevant hemolytic events, could manifested as fatigue, back pain, anemia, dark urine and jaundice, adjudicated by the adjudication committee ultimately.

    90±5 days.

Secondary Outcomes (11)

  • Change in hemoglobin.

    4 days,10±3 days,27±3 days and 90±5 days.

  • Change in reticulocyte.

    4 days,10±3 days,27±3 days and 90±5 days.

  • Change in unconjugated bilirubin and total bilirubin.

    4 days,10±3 days,27±3 days and 90±5 days.

  • Change in lactic dehydrogenase.

    4 days,10±3 days,27±3 days and 90±5 days.

  • Proportion of major bleed (GUSTO definition).

    90±5 days.

  • +6 more secondary outcomes

Eligibility Criteria

Age40 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Concomitant infections at the time of randomization
  • mRS\>2 prior to the presenting stroke
  • Hemoglobin\<10 g/dL prior to randomization
  • Received intravenous thrombolytic therapy or neurointervention treatment before randomization
  • Clear indication for anticoagulation (presumed cardioembolism, eg, atrial fibrillation, prosthetic cardiac valves or suspected endocarditis)
  • Clear indication for dual antiplatelet therapy (eg, minor stroke in 24h (NIHSS ≤3) or endovascular therapy for the indexed event)
  • Anticipated concomitant antiplatelets other than aspirin or clopidogrel (eg, GPIIb/IIIa inhibitors, ticlopidine, prasugrel, dipyridamole, ozagrel, cilostazol, ticagrelor) and other antithrombotic agents with antiplatelet effects, including traditional/herbal medicine agents.
  • Anticipated concomitant therapy with long-term (\>7 days) NSAIDs affecting platelet function
  • Contraindication to clopidogrel or aspirin (1)Known allergic reactions (2)Severe hepatic or renal dysfunction (Severe hepatic dysfunction is defined as serum ALT or AST \>2 times the upper limit of the normal group;Severe renal dysfunction is defined as serum creatinine \> 1.5 times the upper limit of the normal group) (3)Severe cardiac failure(NYHA class Ⅲ or Ⅳ) (4)Asthma (5)Any history of Hemostatic disorder or systemic bleeding (6)Any history of thrombocytopenia or neutropenia (7)Any history of drug-induced hematologic or hepatic insufficiency (8)Low white blood cell (\<2×10\^9/L) or platelet count (\<100×10\^9/L)
  • Any history of thalassemia, autoimmune hemolytic disease, aplastic anemia or other severe hematologic diseases
  • Anticipated concomitant therapy with other contraindicated drugs for G6PD deficiency
  • Severe dysphagia to unable swallow the drugs
  • Concomitant infections and need for antimicrobial therapy
