Description of intervention(s) / exposure
The study will be conducted in 3 parts.
Part1 MAD will consist of approximately 32 healthy subjects enrolled in up to 4 sequential Multiple Ascending Dose (MAD) dose cohorts and each cohort can commence after the corresponding dose Single Ascending Dose (SAD) cohort has been completed and after Safety Review Committee approval.
Each participant in all the 4 cohorts will receive oral doses of iN1011-N17 with matching placebo.
Dosage Form: Capsules
Mode of Administration: Oral
Cohort 1: Healthy participants will receive oral dose of 100 mg iN1011-N17 twice daily (b.i.d) from Day 1 to Day 6, approximately 12 hours apart between the 2 daily doses and receive the morning last dose on Day 7
Cohort 2: Healthy participants will receive oral dose of 200 mg iN1011-N17 twice daily (b.i.d) from Day 1 to Day 6, approximately 12 hours apart between the 2 daily doses and receive the morning last dose on Day 7
Cohort 3: Healthy participants will receive oral dose of 400 mg iN1011-N17 twice daily (b.i.d) from Day 1 to Day 6, approximately 12 hours apart between the 2 daily doses and receive the morning last dose on Day 7
Cohort 4: Healthy participants will receive oral dose of 800 mg iN1011-N17 twice daily (b.i.d) from Day 1 to Day 6, approximately 12 hours apart between the 2 daily doses and receive the morning last dose on Day 7
Each cohort will enrol distinct group of participants
Participants will be confined to the investigational site/institution and supervised for approximately 10 days (Day -1 to Day 9) and will be discharged from the investigational site/institution on Day 9, following satisfactory completion of all procedures and assessments.
iN1011-N17 will be administered as an oral suspension (Cohort 1) and Nano Suspension powder capsule (Cohorts 2-5)
Part 2: Approximately 16 participants will be enrolled into the study. It will be a open label study, cross over bioavailability study which will commence after completion of Part 1 with 2 cohorts. Here the participants in cohort 5 and 6 will receive both Regimen A (single dose of 400 mg iN1011-N17 hydrochloride salt capsule) and Regimen B (single dose of 400 mg iN1011-N17 mesylate salt capsule). Participants will receive a single oral dose of each study treatment (Regimens A and B), one during each of the 2 inpatient periods, in a randomized sequence of administration: AB (Cohort 5) or BA (Cohort 6).
Part 3: MAD Study in Healthy Volunteers and Post-Herpetic Neuralgia Patients with iN1011-N17 Mesylate Salt (14 Days). This will enroll 8 healthy volunteers and 8 PHN patients who will be randomised in a ratio of 3:1 to receive iN1011-N17 or placebo. MAD Cohort 7 will commence after SRC review and assessment of the safety data from Part 2 of the study.
Cohort 7- Healthy volunteers will receive oral dose of 400mg of iN1011-N17 mesylate salt capsule or placebo twice daily (b.i.d) from Day 1 to Day 13, approximately 12 hrs gap between 2 daily doses and receive last dose on Day 14 in the morning.
Cohort 8- Post hepatic Neuralgia participants will an oral dose of 400mg of iN1011-N17 mesylate salt capsule or placebo twice daily (b.i.d) from Day 1 to Day 13, approximately 12 hrs gap between 2 daily doses and receive last dose on Day 14 in the morning.
