- Brief Summary
Randomized, controlled, open study to evaluate the efficacy and safety of Hetrombopag in the treatment of chemotherapy-induced thrombocytopenia(CIT) in patients with acute myeloid leukemia
- Detailed Description
This study is a prospective, single center, randomized, controlled and open clinical trial initiated by the researchers to evaluate the efficacy and safety of Hetrombopag in the treatment of thrombocytopenia caused by chemotherapy in acute myeloid leukemia. The study focuses on acute myeloid leukemia patients aged 18-70 who have completed induction chemotherapy and achieved complete remission, and have received ≤ 1 course of intensive therapy for consolidation. Patients were randomly divided into the treatment group and the control group through the random number table by 1:1. The treatment group received Hetrombopag and platelet transfusion, and the control group did not receive other platelet raising therapy except platelet transfusion. The study used the proportion of subjects with effective treatment during the randomized treatment period as the main efficacy indicator. 72 patients are planned to be enrolled, with treatment group and control group=1:1.

- Participant whose Expected survival time ≥3 months, and who can receive at least 2 cycles of intensive chemotherapy;
- ECOG performance status <=2;
- Participants of childbearing age who agree to use reliable contraceptive methods;
- Patients signed the informed consent form and volunteered to participate in this study with good compliance;
- Participant has any history of hematologic diseases other than chemotherapy-induced thrombocytopenia;
- Participant has a history of arterial or venous thrombosis within 6 months before screening (stroke, transient ischemic attack, myocardial infarction, deep vein thrombosis, or pulmonary embolism), or has clinical symptoms and medical history suggestive of thrombophilia;
- Participant has a history of severe cardiovascular disease within 6 months before screening, such as congestive heart failure (NYHA class III-IV), arrhythmia known to increase the risk of thromboembolism (atrial fibrillation), post-coronary stent implantation, angioplasty, or coronary artery bypass grafting;
- Known human immunodeficiency virus infection,or hepatitis C infection (if hepatitis B surface antigen is positive, or hepatitis B surface antigen is negative but hepatitis B core antibody is positive, HBV-DNA testing is required, if virus replication is suggested, the subject should be excluded);

- Participant participated in other clinical trials within 3 months before enrollment;
- Previous use of thrombopoietin receptor agonist (TPO-RA), recombinant human TPO, recombinant human interleukin-11(rhlL-11) within 1 month before screening;
- Received platelet transfusions within 3 days before enrollment;
- Patients with known or expected allergy or intolerance to the active ingredient or excipients of hetrombopag;
- Inability to understand the nature of the study or failure to obtain informed consent;
- The investigator considers that there are any other conditions that may prevent the subject from completing the study or present a significant risk to the subject;
