Study of N91115 in Patients With Cystic Fibrosis Homozygous F508del-CFTR Mutation (SNO4)
A Phase 1b, Randomized, Double-Blind, Placebo-Controlled, Parallel, Group Study of N91115 to Evaluate Safety and Pharmacokinetics in Patients With Cystic Fibrosis Homozygous for the F508del-CFTR Mutation
調査の概要
詳細な説明
Study procedures, frequency and timing are provided in the attached study schema. Adverse events and concomitant medication will be monitored throughout the study from informed consent signing until end of study participation. A Data Monitoring Committee (DMC) will also review unblinded safety data on a monthly basis throughout the study. Limitations on bronchodilators for pulmonary assessments prior to study drug dosing are described below except in emergent situations.
- Short acting β-agonists and anticholinergics will be held for at least 4 hours
- Long acting β-agonists dosed twice daily will be held for at least 12 hours
- Long acting β-agonists dosed once daily and long acting anticholinergics will be held for at least 24 hours
Screening (Day -28 to Day -3):
Patients will sign the informed consent and undergo procedures to determine eligibility including pregnancy testing, demographic information, medical history, and genotype by historical confirmation or blood sample confirmation (as applicable), height and weight, 12-Lead electrocardiogram (ECG), 48-hour Holter monitoring, chemistry, hematology, full physical examination, sweat chloride, smoking and alcohol history, spirometry, sputum microbiology, urinalysis and vital signs.
Day 1 Predose (Day -2 to -1) Patients will return to the clinic to reconfirm eligibility and assess any changes in medical history and pregnancy status. An abbreviated physical examination focusing on cardiovascular, pulmonary and gastrointestinal systems plus an assessment of weight will be conducted. The following will be obtained: 12-lead ECG, abbreviated physical exam, blood for DNA (optional), blood for leukocyte messenger ribonucleic acid (mRNA), blood inflammatory biomarkers, cystic fibrosis questionnaire-revised (CFQ-R), O2 Sat, patient global impression of change (PGIC), safety labs, serum pharmacokinetics (PK), spirometry, sputum microbiology, sweat chloride (SC) (if more than 2 weeks since the screening value was obtained), and vital signs. Sites may choose to perform any of these assessments on Day -2, Day -1 or Day 1 predose except for serum PK that starts Day 1 predose and vital signs that are done Day 1 predose.
Dosing and Food Intake:
Patients will take their dose of study drug every 12 hours at approximately the same time each morning and night. There are no restrictions related to food intake.
Dosing Days 1 and 2:
On Day 1, patients will be observed for at least 4 hours following the first dose of study drug. Patients return to the clinical site on Day 2 for a predose PK sample that is 24 hours after their first dose. Patients will be observed for at least 2 hours after the second dose on Day 2.
Days 3-28:
Patients self-administer study drug at approximately the same time each morning and evening with the exception that the morning doses on clinic Days 7, 14, 21 and 28, which will be administered and witnessed in the clinic.
Day 7 (Dosing in Clinic):
On Day 7, patients will return to the clinic to monitor any changes in health status and for an abbreviated physical exam, 12-Lead ECG, O2 Sat, safety labs, PK, spirometry, study drug compliance, SC and vital signs.
Day 14 (Dosing in Clinic):
On Day 14, patients will return to the clinic to monitor any changes in health status and for an abbreviated physical exam, urine pregnancy, 12-lead ECG, blood inflammatory biomarkers, CFQ-R, O2 Sat, safety labs, PK, spirometry, study drug compliance, SC and vital signs.
Day 21 (Dosing in Clinic):
On Day 21, patients will return to the clinic to monitor any changes in health status and for an abbreviated physical exam, 12-Lead ECG, O2 Sat, safety labs, PK, spirometry, study drug compliance, SC and vital signs.
Day 28 (Dosing in Clinic):
On Day 28 patients will return to the clinic to monitor any changes in health status and for an abbreviated physical exam, 12-Lead ECG, blood for DNA (optional), blood for leukocyte mRNA, blood inflammatory biomarkers, CFQ-R, urine pregnancy, O2 Sat, PGIC, safety labs, PK, spirometry, sputum microbiology, study drug compliance, SC, weight, and vital signs.
Day 42 (Final study day 2 weeks after last dose):
On Day 42 (± 2 days) study follow-up assessments include: abbreviated physical exam, blood inflammatory biomarkers, O2 Sat, PGIC, spirometry, SC, weight, and vital signs.
