Study summary

The purpose of the study is to evaluate the pharmacokinetic effects and safety and tolerability of VX-407 when coadministered with oral contraceptives.

Read the detailed description

The purpose of the study is to evaluate the pharmacokinetic effects and safety and tolerability of VX-407 when coadministered with oral contraceptives. This clinical trial information was submitted voluntarily under the applicable law and, therefore, certain submission deadlines may not apply. (That is, clinical trial information for this applicable clinical trial was submitted under section 402(j)(4)(A) of the Public Health Service Act and 42 CFR 11.60 and is not subject to the deadlines established by sections 402(j)(2) and (3) of the Public Health Service Act or 42 CFR 11.24 and 11.44.).

Eligibility criteria

Key Inclusion Criteria:

  • (BMI) of 18.0 to 30.0 kilogram per meter square (kg/m\^2), inclusive
  • A total body weight of greater than (>) 50 kg

Key Exclusion Criteria:

  • History of febrile illness within 5 days before the first dose of study drug
  • Pregnant, nursing, or planning to become pregnant during the study or within 90 days after the last dose of study drug

Other protocol defined Inclusion/Exclusion criteria will apply.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
