Description of intervention(s) / exposure
XG005 Tablet 250 mg (equivalent to 125 mg of naproxen and 87 mg of pregabalin) taken orally.

The planned treatments in the Single Ascending Dose (SAD) portion (Part 1) are as follows:
Cohort 1: XG005 250 mg or matching placebo
Cohort 2: XG005 500 mg or matching placebo
Cohort 3: XG005 1000 mg or matching placebo
Cohort 4: XG005 1250 mg or matching placebo
It is planned for cohorts in the SAD portion to be dosed approximately 1 week apart, following escalation approval by the Safety Review Committee (SRC).

The Multiple Ascending Dose (MAD) portion (Part 2) will include a titration period; the plan for which is as follows:
Cohort 1: Day 1- XG005 250 mg or matching placebo, once.
Cohort 2: Day 1- XG005 250 mg or matching placebo, once. Days 2 and 3- XG005 250 mg or matching placebo, two times per day (12 hours apart).
Cohort 3: Day 1- XG005 250 mg or matching placebo, once. Days 2 and 3- XG005 250 mg or matching placebo, two times per day (12 hours apart). Days 4 and 5- XG005 500 mg or matching placebo, two times per day (12 hours apart).
Cohort 4: Day 1- XG005 250 mg or matching placebo, once. Days 2 and 3- XG005 250 mg or matching placebo, two times per day (12 hours apart). Days 4 and 5- XG005 500 mg or matching placebo, two times per day (12 hours apart). Days 6 and 7- XG005 1000 mg or matching placebo, two times per day (12 hours apart).
The titration period will be followed by the target dosing period.
During the target dosing period, participants will receive study drug twice daily for 7 days, 12 hours apart (only morning dose on Day 7). The planned treatments in the MAD target dosing period are as follows:
Cohort 1: XG005 250 mg two times per day or matching placebo
Cohort 2: XG005 500 mg two times per day or matching placebo
Cohort 3: XG005 1000 mg two times per day or matching placebo
Cohort 4: XG005 1250 mg two times per day or matching placebo
It is planned for cohorts in the MAD portion to commence the target dosing approximately 1 month apart, following escalation approval by the Safety Review Committee (SRC).

Subjects who participate in Part 1 of the study will be given the option to also participate in Part 2 of the study (if eligible).
Adherence to the study treatments will be monitored by inpatient stay and observation; participants in both SAD and MAD portions will be confined to the study unit from check-in on Day -1 through to discharge at 72-hour post last dose.

Outcomes
Primary outcome [1] 320899 0
The composite primary outcome is to determine the plasma and urinary PK profile of single and multiple oral doses of XG005 in healthy subjects.
Blood samples will be collected and the following PK parameters will be assessed in plasma-
Part 1:
Peak concentration (Cmax)
Time to peak concentration (Tmax)
terminal elimination rate constant (Kel)
half-life (t1/2)
Apparent oral clearance (CL/F)
Apparent oral volume of distribution (Vd/F)
Area under the concentration-time curve from time 0 to the last measurable concentration timepoint (AUC0-t)
Area under the concentration-time curve from time 0 and extrapolated to infinity (AUC0-infinity)
Part 2:
maximal concentration at steady-state (Cmax,ss)
minimum concentration (Cmin)
Tmax
Kel
t1/2
steady-state oral clearance (CLss/F)
steady-state volume of distribution (Vss/F)
area under the concentration-time curve for the dosing interval (AUC0-T)

Urine samples will also be collected and the following PK parameters assessed:
the amount of the analyte excreted in urine during each collection interval (Aet1-t2)
Cumulative percentage of dose excreted in urine (% dose excreted, %Ae)
renal clearance (CLr)
Timepoint [1] 320899 0
Blood samples for PK will be collected at the following timepoints:
Pre-morning dose on Days 2–6 of target dose (Part 2 only)
Pre-morning dose, and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, and 72-hours post-morning dose on Day 1 (Part 1) and Day 7 of target dose (Part 2).

Urine samples for PK will be collected at the following intervals on Day 1 (Part 1) and Day 7 of target dose (Part 2):
Pre-morning dose, 0–4 hours, 4–8 hours, 8–12 hours, 12–24 hours, 24–36 hours, 36—48 hours, and 48–72 hours post-morning dose.
Secondary outcome [1] 373294 0
To determine the safety and tolerability of XG005 when administered orally as a single ascending
dose (SAD) and as a multiple ascending dose (MAD) to healthy subjects.
This will be assessed by looking at the incidence, severity, causality, and seriousness of adverse events;
changes in clinical laboratory evaluations; changes in vital signs parameters, and ECGs; and Columbia-Suicide Severity Rating Scale (C-SSRS)
Timepoint [1] 373294 0
Adverse event information will be recorded from the time of admission to the study unit until 7 days after
the last dose of study drug.
Clinical laboratory evaluations of serum chemistry, hematology, and urinalysis will be performed at Screening, Check-in (Day -1), on Day 3 of target dosing (Part 2 only), at Discharge from clinic (72 hours post last dose), and Follow-up/Early Withdrawal.
Vital signs, including blood pressure, pulse rate, and body temperature will be measured at Screening (including respiration rate); Check-in (Day -1); Pre-dose, and 2, 4, 8, 12 and 72 hours post-dose (Day 1, Part 1, and Day 7 of target dose in Part 2); Daily prior to the morning dose during dose titration and on Day 1 of target dosing (Part 2); Follow-up/Early Withdrawal (including respiration rate).
12-lead ECGs will be obtained at: Screening; Check-in (Day -1); Pre-dose and 1, 2, 4, 8, and 72 hours post-dose (Day 1, Part 1, and Day 7 of target dose in Part 2); Daily prior to the morning dose during dose titration and on Day 1 of target dosing (Part 2); Follow-up/Early Withdrawal
C-SSRS will be obtained in Part 2 at Screening, discharge and the Follow Up/Early Withdrawal visit.
