Brief summary

The goal of this clinical trial is to Assess the Effect of Food on the Pharmacokinetics (PK) of D3S-001 in Healthy Adult Participants. The main question\[s\] it aims to answer are: 1. Evaluate the PK of D3S-001 administered in the fasted and fed state in healthy adult participants. 2. Evaluate the safety and tolerability of D3S-001 administered in the fasted and fed state in healthy adult participants. Potential participants will be screened within 28 days prior to the first dose. Participants will be admitted into the clinical research unit (CRU) on Day -1 and will be confined until end of study (EOS) or until early termination. On Day 1, participants will be randomised to Group 1 or Group 2. Participants will receive Treatment A or Treatment B in each of 2 periods (Periods 1 and 2; Study Days 1 and 4), once under fasted conditions (Treatment A) and once under fed conditions (Treatment B). Each participant will receive both treatments.

Interventions

The investigational product dose: 600 mg D3S-001 capsules. A 600-mg oral dose of D3S-001 will be given to potential participants on Day 1 and Day 4.

Intervention model description

This will be a Phase 1, single-centre, open-label, randomised, crossover study in healthy adult male and female participants. Potential participants will be screened within 28 days prior to the first dose. Participants will be admitted into the clinical research unit (CRU) on Day -1 and will be confined until end of study (EOS) or until early termination. On Day 1, participants will be randomised to Group 1 or Group 2. Participants will receive Treatment A or Treatment B in each of 2 periods (Periods 1 and 2; Study Days 1 and 4), once under fasted conditions (Treatment A) and once under fed conditions (Treatment B).

Design outcomes

Primary

MeasureTime frameDescription
Maximum Observed Concentration (Cmax)From screening to end of treatment at 34 daysMaximum Observed Concentration (Cmax) of D3S-001 administered in the fasted and fed state.
Area under the concentration-time curveFrom screening to end of treatment at 34 daysEvaluate the area under the concentration-time curve from time zero to the time of the last quantifiable concentration after D3S-001 administered in the fasted and fed state.

Secondary

MeasureTime frameDescription
Adverse eventsFrom screening to end of study (approximately 34 days)Subjects will be observed for any signs or symptoms of adverse events and asked about their condition by open questioning, such as "How have you been feeling since you were last asked?", at least once each day while resident at the study site and at each study visit.
Number of clinically significant clinical laboratory findingsOn Screening visit, Day -1, Days 2-3 and Days 5-6 (End of Study)Evaluate the safety and tolerability of the drug through clinical laboratory assessments, including clinical chemistry, haematology, coagulation, and urinalysis.
Number of clinically significant electrocardiogram parametersOn screening day, Day -1 and Days 1-6 (End of Study)Evaluate the safety and tolerability of the drug using resting 12-lead electrocardiogram (ECG) parameters, recorded after the subject has been supine and at rest for at least 5 minutes. The following ECG Measurements will be recorded: Heart Rate, RR Interval, PR Internal, QRSD QT Interval, QTcB and QTcF.
To determine the safety and tolerability of the drug in healthy subjects, as assessed by the collection of vital signs.On screening day, Day -1 and Days 1-6 (End of Study)Temperature in Degrees Celsius (℃)
Number of clinically significant physical examinationsOn Screening visit, Day -1 and Day 6 (End of Study)Evaluate the safety and tolerability of the drug by performing HEENT \[head, eyes, ears, nose, and throat\], mouth/dental, neck \[including thyroid \& nodes\], cardiovascular, respiratory, gastrointestinal, renal, neurological, musculoskeletal, skin, and other examinations.
