NCT06896760 | Not Yet Recruiting Phase 1

• 1 other identifier: ABSK-011-103
• Study Type: interventional
• Target: 6
• Locations: 1 country
• Sites: 1

Brief Summary

This study is a single-site, open-label, single-cohort, single-dose study to assess the absorption, metabolism, and excretion profile of \[14C\] ABSK011 in healthy adult male subjects. The study plans to enroll 6 to 8 healthy male subjects to ensure at least 6 evaluable subjects.

Conditions

Healthy Subjects

Outcome Measures

Primary Outcomes (3)

• Cumulative excretion rate of radioactivity in excreta (urine, feces) and total radioactivity (urine and feces)

  To assess the routes and rates of elimination of ABSK011 and its metabolites after single oral administration of \[14C\]ABSK011 in healthy adult male subjects

  All excreted urine and feces samples at specified time points during 0-192 hours after dosing will be collected.

• Percentage of each metabolite in urine and feces relative to the administered dose (% administered dose), or percentage of metabolites in plasma relative to total exposure AUC (% AUC);

  To determine the metabolism and elimination pathways of ABSK011 after single oral administration of \[14C\] ABSK011 in healthy adult male subjects, and identify major metabolites.All excreted urine and feces samples at specified time points during 0-192 hours after dosing will be collected.

  Conduct testing within 1 month after all subjects collect plasma, urine, and fecal samplesat all time points required by the protocol

• %AUC

  To evaluate the pharmacokinetics of ABSK011 and its major metabolites in the urine of healthy adult male subjects after a single oral administration \[14C\] of ABSK011.

  Conduct testing within 1 month after all subjects collect all samples at all time points required by the protocol

Secondary Outcomes (1)

• Frequency, type and severity of adverse events/serious adverse events; changes in vital signs, 12-lead ECGs, laboratory tests, etc.

  From signing the ICF until 9 days after the first dosing

Study Arms (1)

[14C]ABSK011

EXPERIMENTAL

Participants will receive a single oral administration of approximately 200 mg/120 µCi \[14C\]ABSK-011 suspension after a low-fat breakfast on day 1 morning.

Drug: [14C]ABSK011

Interventions

[14C]ABSK011 DRUG

The standard meal was taken the night before administration, and the patient was fasted for at least 10 h without drinking water overnight. The next morning, eat a low-fat meal, finish the meal within 30 minutes, and take the test drug with warm water 30 minutes (±5 minutes) after the beginning of the meal. The total volume of warm water and suspension liquid is about 240 mL. Except for meals and administration, no water was allowed 1 hour before and 1 hour after medication. No food is allowed for 4 hours after taking the medication. Throughout the study, participants received meals provided by the center at approximately the same time each day.
