入选标准
- •Patients must meet all of the following inclusion criteria in order to
- •participate in this study:
- •1.The patient is willing and able to provide signed informed consent
- •prior to any protocol-required procedures to be performed.
- •2.The patient is at least 18 years of age at the time of randomization.
- •3.The patient's Tanner Stage should be = 4 prior to randomization.
- •4.The patient has a diagnosis of Gaucher disease type 1 confirmed by a documented deficiency of acid ß-glucosidase activity by enzyme assay.
- •5.The patient consents to provide a blood sample for genotyping for
- •Gaucher disease, chitotriosidase, and cytochrome P450 2D6 (CYP2D6, to categorize the patient's predicted rate of metabolism), if these genotyping results are not already available for the patient.
- •6.The patient has received treatment with ERT for at least 3 years. For at least 6 of the 9 months prior to randomization, the patient has received a total monthly dose of 30 to 130 U/kg of ERT that has received approval by at least one regulatory authority by the time of randomization.
- •7.The patient has reached Gaucher disease therapeutic goals prior to randomization. Gaucher disease therapeutic goals are defined as a patient with all of the following:
- •A.No bone crisis and free of symptomatic bone disease such as bone pain attributable to osteonecrosis and/or pathological fractures within the last year.
- •B.Mean hemoglobin level of = 11 g/dL if female and = 12 g/dL if male at the time of screening.
- •C.Mean platelet count = 100,000/mm3 at the time of screening.
- •8.Spleen volume < 10 times Normal or total splenectomy (provided the splenectomy occurred > 3 years prior to randomization).
- •9.Liver volume < 1.5 times Normal.
- •10.Female patients of childbearing potential must have a documented negative pregnancy test prior to randomization. In addition, all female patients of childbearing potential must use a medically accepted form of contraception throughout the study (either a barrier method or hormonal contraceptive with ethinyl estradiol and norethindrone or similar active components).
- •11.The patient is willing to abstain from consumption of grapefruit,
- •grapefruit juice, or grapefruit products for 72 hours prior to
- •administration of the first dose of study medication (Genz 112638 or Cerezyme) and, if randomized to Genz 112638, for the duration of the primary analysis period.
- •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 150
- •F.1.3 Elderly (>=65 years) yes
- •F.1.3.1 Number of subjects for this age range 0
排除标准
- •Patients will be excluded from participation in this study if they meet
- •any of the following exclusion criteria:
- •1.The patient received substrate reduction therapies for Gaucher disease within 6 months prior to randomization.
- •2.The patient has had a partial or total splenectomy within 3 years prior to randomization.
- •3.The patient has any evidence of neurologic (e.g., peripheral
- •neuropathy, tremor, seizures, Parkinsonism or cognitive impairment) or pulmonary involvement (e.g., pulmonary hypertension) as related to Gaucher disease.
- •4.The patient is transfusion-dependent.
- •5.The patient has documented prior esophageal varices or liver
- •infarction or current liver enzymes (alanine transaminase
- •[ALT]/aspartate aminotransferase [AST]) or Total Bilirubin > 2 times the upper limit of normal (ULN), unless the patient has a diagnosis of Gilbert Syndrome.
- •6.The patient has any clinically significant disease, other than Gaucher disease, including cardiovascular, renal, hepatic, gastrointestinal, pulmonary, neurologic, endocrine, metabolic (e.g. hypokalemia, hypomagnesemia), or psychiatric disease, other medical conditions, or serious intercurrent illnesses that may preclude participation in the study.
- •7.The patient is known to have any of the following: Clinically significant coronary artery disease including history of myocardial infarction (MI) or ongoing signs or symptoms consistent with cardiac ischemia or heart failure; or clinically significant arrhythmias or conduction defect such as 2nd or 3rd degree atrioventricular (AV) block, complete bundle branch block, prolonged QTc interval, or sustained ventricular tachycardia (VT).
- •8.The patient has tested positive for the human immunodeficiency virus (HIV) antibody, Hepatitis C antibody, or Hepatitis B surface antigen.
- •9.The patient has received an investigational product within 30 days
- •prior to randomization.
- •10.The patient is scheduled for in-patient hospitalization, including
- •elective surgery, during the study.
- •11.The patient has a history of cancer within 5 years of randomization, with the exception of basal cell carcinoma.
- •12.The patient is pregnant or lactating.
- •13.The patient has received any medication that may cause QTc interval prolongation within 30 days prior to randomization. Exception:
- •Diphenhydramine (Benadryl) or other medications used as
- •premedication for ERT infusions are allowed up to 7 days prior to randomization.
- •14.The patient has received any medication that may induce CYP3A4
- •within 30 days prior to randomization, with the exception of
- •premedications for ERT infusion, which are allowed up to 7 days prior to randomization.
- •15.The patient is not a CYP2D6 poor metabolizer, or is an indeterminate metabolizer with one allele identified as active, and has received any medication that is a strong inhibitor of CYP3A4 or CYP2D6 within 30 days prior to randomization, with the exception of the following:
- •premedications for ERT infusion, which are allowed up to 7 days prior to randomization;
- •a strong inhibitor of CYP3A4 or a strong inhibitor of CYP2D6 (but not both medications) that has been administered chronically for at least 30 days prior to randomization and will be continued on the same dosing regimen during the primary analysis period.
- •16.The patient is a CYP2D6 poor metabolizer or an indeterminate
- •metabolizer with neither allele known to be active and has received any medication that is a strong inhibitor of CYP3A4 within 30 days prior to randomizat
