Descriptive Information
Brief Title  ICMJE A DDI Study of FDL169 and FDL176 in Healthy Subjects
Official Title  ICMJE A Phase 1/2, Drug-Drug Interaction Study of FDL169 and FDL176 in Healthy Subjects and in Cystic Fibrosis Subjects Homozygous for the F508del-CFTR Mutation
Brief Summary A DDI study to assess the safety, tolerability and pharmacokinetics of both; doses of FDL176 with and without co-administration of FDL169 and doses of FDL169 with and without co-administration of FDL176.
Detailed Description This is an open-label, non-randomised study. Enrolment will be in two parallel and independent parts. Part 1 will assess the safety, tolerability and pharmacokinetics of single doses of FDL176 with and without co-administration of FDL169. Part 2 will assess the safety, tolerability and pharmacokinetics of repeated doses of FDL169 with and without co-administration of FDL176.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Healthy males or non-pregnant, non-lactating healthy females

  • Must agree to follow the study's contraception requirement

Exclusion Criteria:

  • Prior or ongoing medical condition, medical history, physical findings, ECG findings or laboratory abnormality that, in the Investigator's (or delegate's) opinion, could adversely affect the safety of the subject or would place the subject at increased risk.
  • History of long QT syndrome and/or QT corrected according to Fridericia's formula (QTcF) interval (>450 msec) or QTcF >450 msec at Screening or Day -1.
  • Presence or history of clinically significant allergy requiring treatment, as judged by the investigator. Hayfever is allowed unless it is active.
  • Use of any prescription drugs within 14 days or 5 half-lives (whichever is longer) before the first dose of IMP.
  • Use of any non-prescription drugs, including vitamins, herbal and dietary supplements within 14 days or 5 half-lives (whichever is longer) before the first dose of IMP.
  • Use of any prescription and non-prescription medications that are strong inhibitors or moderate inducers of cytochrome P450 3A, within 14 days or 5-half-lives (whichever is longer) before the first dose of IMP. Use of any prescription and non-prescription medications that are strong inducers of cytochrome P450 3A within 28 days before the first dose of IMP.

  • Pregnant or nursing females.
  • History of regular alcohol consumption within 6 months of the study
  • Current smoking or use of tobacco products or substitutes.
  • Poor peripheral venous access.
  • Donation of ≥470 mL blood or loss of blood during surgery or due to trauma within 3 months prior to Day 1.
