Is this trial a fit for you?

Likely a good fit

Adults with autosomal dominant polycystic kidney disease who meet BMI, weight, and bowel movement criteria and have no conditions affecting drug handling.

Probably not a fit

Patients with comorbidities or conditions affecting absorption or radiation exposure limits may not benefit from this study.

What this trial studies

This Phase 1 interventional trial administers a single oral dose of radiolabeled VX-407 to eligible adults to characterize its pharmacokinetic profile. Safety and tolerability are also monitored to identify any immediate adverse effects. The study relies on precise measurement of the radiolabeled compound to track absorption, distribution, metabolism, and excretion. It is conducted at a single center with a sponsor focus on early pharmacology data for VX-407. Participants are selected by BMI, weight, stool frequency, and general health criteria to minimize variability.

Why it matters

Potential benefit: Participants may not directly benefit, but the information could help determine dosing for future studies of VX-407 in kidney disease.

How similar studies have gone: Prior pharmacokinetic studies using radiolabeled compounds have successfully mapped ADME profiles in early-phase trials, supporting this approach's validity.

Key Inclusion Criteria:

* Body mass index (BMI) of 18.0 to 32.0 kilogram per meter square (kg/m\^2), inclusive
* A total body weight of more than (\>) 50 kg
* Participants must have regular bowel movements (i.e., average of more than or equal to (\>=) 1 and less than or equal to (\<=)3 stools per day)

Key Exclusion Criteria:

* History of febrile illness or other acute illness that has not fully resolved within 14 days before the first dose of study drug
* Any condition possibly affecting drug absorption, distribution, metabolism, or excretion
* Exposure to any nonenvironmental radiation (e.g., diagnostic medical imaging or occupational exposure) within 12 months before study drug administration
* Participation in more than 1 radiolabeled study (if the previous study's radiation exposure is unknown) or participation in more than 3 radiolabeled studies (if the previous studies' radiation exposure is known) in the 12 months before dosing or if the annual whole-body radiation exposure from all previous studies (including this dosing) is more than the FDA-allowed maximum whole body radiation exposure of 5000 mrem

Other protocol defined Inclusion/Exclusion criteria will apply.
