Brief summary

This was an open-label study to evaluate the absorption, distribution, metabolism, and excretion of radioactivity in healthy male participants following a single 150-milligram (mg) oral dose of carbon-14 (\[14C\])-ACH-014447 (\[14C\])-danicopan) containing approximately 100 microcuries (µCi) of \[14C\].

Inclusion criteria

Key Inclusion Criteria: * Healthy was defined as having no clinical relevant abnormalities identified by a detailed medical history, physical exam, blood pressure and pulse rate measurements, 12-lead electrocardiogram, and clinical laboratory tests. * Body mass index of ≥ 18 and ≤ 30 kilograms (kg)/meter squared and weight of ≥ 50 kg and ≤ 100 kg. * Regular daily bowel movements (that is, production of at least 1 stool per day). * Non-smoker or ex-smoker who had not used tobacco or nicotine products for ≥ 3 months prior to screening. Key

Exclusion criteria

* History or clinically relevant evidence of significant cardiovascular, pulmonary, hepatic, renal, hematological, gastrointestinal, endocrine, immunologic, dermatologic, neurological, or psychiatric disease. * History of conditions or procedures possibly affecting drug absorption or excretion. A history of appendectomy, cholecystectomy, and hernia repair was allowed if they were not associated with complications. * Active bacterial infection or clinically significant active viral infection, a body temperature \> 38°Celcius, or other evidence of infection on Day 1, or with a history of febrile illness within 7 days prior to Day 1. * Healthy participants who had been exposed to significant radiation levels of \> 5 millisieverts in the last year prior to screening. * Clinically significant laboratory abnormalities at screening or Day -1, as well as absolute neutrophil counts, platelets, and hemoglobin outside of reference ranges.

Secondary

MeasureTime frameDescription
Incidence Of Treatment-emergent Adverse EventsDay 1 through Day 10
Percentage Of Total Radioactivity Detected For Each [14C]-Danicopan Metabolite in Plasma, Urine, And FecesUp to 96 hours postdose or maximum of 216 hours postdose for extended collection period\[14C\]-Danicopan metabolic profiling in plasma, urine, and feces was performed in samples containing sufficient amounts of radioactivity. The percent of dose represented by each of the metabolites was calculated using the radioactivity concentration equivalent data combined with the metabolic profiling data. The percentage of each identified metabolite to total radioactivity in plasma was estimated based on plasma metabolic profiling data.
