入选标准
- •1.Male or female aged =18 to =65 years at the time of informed consent form (ICF) signing.
- •2.Confirmed diagnosis of SCD (HbSS, HbSß0 thalassemia, or HbSß+ thalassemia) in the medical record; if not available, the diagnosis must be confirmed at the site’s local laboratory instead.
- •3.Subjects must have had at least 2 and no more than 12 documented episodes of VOC in the past 12 months at the time of ICF signing and at randomization (Day 1).
- •For study eligibility, VOC is defined as a documented episode of an acute painful crisis (for which there was not an explanation other than VOC) that involved moderate to severe pain lasting for at least 2 hours and at least one of the following:
- •Use of escalated analgesia (including healthcare professional-instructed use of an analgesic prescription)
- •A hospital, emergency department, or clinic visit and/or healthcare telephone consultation at the time of occurrence
- •Diagnosis of acute chest syndrome (ACS) (defined as an acute illness characterized by fever and/or respiratory symptoms, accompanied by a new pulmonary infiltrate on a chest X ray), hepatic sequestration, splenic sequestration, or priapism (in males)
- •4.Hb of >5.5 and <10.5 g/dL; Hb values within 21 days post-transfusion will be excluded.
- •5.This inclusion criterion has been removed.
- •6.Subjects receiving HU must have received it continuously for at least 6 months prior to signing the ICF, and must have been on a stable dose for at least 3 months prior to signing the ICF, with no anticipated need for dose adjustments during the study including the screening period, in the opinion of the investigator.
- •7.Female subjects must not be pregnant or breastfeeding and be highly unlikely to become pregnant. Male subjects must be unlikely to impregnate a partner.
- •8.Be capable of giving informed consent and reading and signing the ICF after the nature of the study has been fully explained by the investigator or investigator designee.
- •9.Be willing and able to complete all study assessments and procedures and to communicate effectively with the investigator and site staff.
- •Are the trial subjects under 18? no
- •Number of subjects for this age range:
- •F.1.2 Adults (18-64 years) yes
- •F.1.2.1 Number of subjects for this age range 97
- •F.1.3 Elderly (>=65 years) yes
- •F.1.3.1 Number of subjects for this age range 2
排除标准
- •1.Hospital discharge for sickle cell crisis or other vaso occlusive event within the 4 days prior to randomization (Day 1).
- •2. Subjects participating in a chronic/prophylactic RBC transfusion program (i.e., regularly scheduled RBC transfusions); any transfusions within 21 days of screening or Baseline Hb measurement.
- •3.Subjects with HbF >25% at screening.
- •4.Subjects with known active hepatitis A, hepatitis B, or hepatitis C, with active or acute event of malaria, or who are known to be positive for human immunodeficiency virus (HIV).
- •5.For female subjects of childbearing potential, a positive serum human chorionic gonadotropin (hCG) test (screening) or a positive urine hCG test at randomization (Day 1).
- •6.Significant kidney disease as indicated by, for example, Estimated glomerular filtration rate (eGFR) <45 mL/min as calculated by the equation from the Modification of Diet in Renal Disease (MDRD) Study using creatinine, age, sex, and ethnicity (modified MDRD formula).
- •7.Alanine aminotransferase or aspartate aminotransferase >3 × the upper limit of normal.
- •8.Body mass index (BMI) <17.0 kg/m2 or >35 kg/m2; or total body weight <45 kg.
- •9.Current or history of malignancies (solid tumors and hematological malignancies), unless the subject has been free of the disease (including completion of any active or adjuvant treatment for prior malignancy) for =5 years. However, subjects with the following history of/concurrent conditions are allowed if, in the opinion of the investigator, the condition has been adequately diagnosed and is determined to be clinically in remission, and the subject’s participation in the study would not represent a safety concern:
- •a.Basal or squamous cell carcinoma of the skin
- •b.Carcinoma in situ of the cervix
- •c.Carcinoma in situ of the breast
- •d.Incidental histologic finding of prostate cancer (T1a or T1b using the tumor, nodes, metastasis clinical staging system)
- •10.History of a clinically significant allergic reaction or hypersensitivity, as judged by the investigator, to any drug or any component of the study drug formulations used in the study (see the Investigator’s Brochure).
- •11.History of unstable or deteriorating cardiac or pulmonary disease within 6 months before signing the ICF, including but not limited to the following:
- •a.Unstable angina pectoris or myocardial infarction or elective coronary intervention
- •b.Congestive heart failure requiring hospitalization
- •c.Uncontrolled clinically significant arrhythmias
- •12.Any condition affecting drug absorption, such as major surgery involving the stomach or small intestine (prior cholecystectomy is acceptable).
- •13.On ECG testing at ICF signing and/or randomization (Day 1), a corrected QT interval, Fridericia’s formula (QTcF) >450 ms in men and >470 ms in women on 2 or more of the triplicate ECGs, or the presence of clinically significant ECG abnormalities as determined by the investigator.
- •14.Major surgery within 8 weeks or minor surgery within 2 weeks of randomization (Day 1).
- •15.Stroke requiring medical intervention within 24 weeks prior to randomization (Day 1).
- •16.Subjects taking direct acting oral anti-coagulants (apixaban, dabigatran, rivaroxaban, edoxaban, or ticagrelor) or taking warfarin, unless they stopped the treatment at least 28 days prior to randomization (Day 1); low molecular weight heparins are allowed in the peri operative period; Aspirin use (<100 mg per day) is allowed before and during the study.
- •17.Poorly controlled diabetes mellitus in the
