This Phase 1 study will evaluate a new formulation of HBW-3220 capsules in healthy adults. It will compare how much and how quickly HBW-3220 enters the bloodstream after a single 120 mg dose of the new formulation versus the previous formulation under fasting conditions, and after the new formulation is taken under fed versus fasting conditions. Twenty-one participants will be randomly assigned to one of three treatment sequences and will receive all three treatments during three study periods, with at least 7 days between doses. Blood samples will be collected for pharmacokinetic analysis, and safety and tolerability will be assessed throughout the study and during follow-up.
HBW-3220 is a reversible Bruton tyrosine kinase (BTK) inhibitor. This is a randomized, open-label, three-period, three-sequence crossover Phase 1 study in 21 healthy adult participants. Participants will be randomized in a 1:1:1 ratio to one of three treatment sequences. During each study period, participants will receive a single 120 mg oral dose of one of the following treatments: the previous formulation of HBW-3220 capsules under fasting conditions, the new formulation under fasting conditions, or the new formulation after a high-fat, high-calorie meal. Each participant will receive all three treatments, with a washout period of at least 7 days between doses. Blood samples for pharmacokinetic assessment will be collected before dosing and through 72 hours after each dose. The primary pharmacokinetic parameters include maximum plasma concentration (Cmax), area under the plasma concentration-time curve from time zero to the last measurable concentration (AUC0-t), and area under the curve extrapolated to infinity (AUC0-inf). Relative bioavailability will be assessed by comparing the new and previous formulations under fasting conditions. The effect of food will be assessed by comparing the new formulation under fed and fasting conditions. Safety and tolerability will be evaluated using adverse events, vital signs, physical examinations, clinical laboratory tests, and 12-lead electrocardiograms. A safety follow-up will be conducted 10 ± 2 days after the last dose.

A single oral dose of 120 mg HBW-3220 old formulation, administered as four 30 mg capsules under fasting conditions.
A single oral dose of 120 mg HBW-3220 new formulation, administered as four 30 mg capsules under fasting conditions.
A single oral dose of 120 mg HBW-3220 new formulation, administered as four 30 mg capsules after a high-fat, high-calorie meal.
Maximum Observed Plasma Concentration (Cmax) of HBW-3220
Maximum observed plasma concentration of HBW-3220 will be calculated from plasma concentration-time data using noncompartmental analysis. Cmax will be compared between the new and old formulations under fasting conditions and between the fed and fasting conditions for the new formulation.
Time frame: Predose and 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 5, 6, 8, 12, 24, 48, and 72 hours after dosing in each of the three treatment periods
Area Under the Plasma Concentration-Time Curve From Time Zero to the Last Quantifiable Concentration (AUC0-t) of HBW-3220
AUC0-t of HBW-3220 will be calculated from plasma concentration-time data using noncompartmental analysis. AUC0-t will be compared between the new and old formulations under fasting conditions and between the fed and fasting conditions for the new formulation.
Time frame: Predose through 72 hours after dosing in each of the three treatment periods
Area Under the Plasma Concentration-Time Curve From Time Zero to Infinity (AUC0-inf) of HBW-3220
AUC0-inf of HBW-3220 will be calculated from plasma concentration-time data using noncompartmental analysis. AUC0-inf will be compared between the new and old formulations under fasting conditions and between the fed and fasting conditions for the new formulation.
Time frame: Predose through 72 hours after dosing in each of the three treatment periods
