3-Way Crossover Study to Compare the PK (Pharmokinetics) and to Evaluate the Effect of Food on the Bioavailability
A Phase 1, Randomized, Open-Label, Single-Dose, 3-Way Crossover Study to Compare the PK of Two Oral Formulations of SMP-100 and to Evaluate the Effect of Food on the Bioavailability of SMP-100 Tablets in Normal Healthy Volunteers
A tanulmány áttekintése
Részletes leírás
SMP-100 is a novel serotonin receptor 3 (5-HT3) partial agonist. The compound is under development in an oral dosage form for the treatment of diarrhea-predominant irritable bowel syndrome (IBS-d). The study drug also has the potential to treat chemotherapy induced nausea and emesis and diarrhea due to carcinoid syndrome.
A single ascending dose (SAD) and multiple ascending dose (MAD) clinical study (study number SMP-100-101) evaluating the safety, tolerability, and PK profile of orally administered SMP-100 in healthy volunteers is ongoing. Regarding safety, there have been no clinically relevant abnormal vital signs, ECGs, laboratory results or SAEs.
In each period, subjects will receive a single 4 mg dose of SMP-100 on Day 1 (Period 1), Day 4 (Period 2), and Day 7 (Period 3), under fasting or fed conditions, followed by 48 hours of PK and safety assessments.
The study will include a screening visit from Day -28 to Day -2. Eligible subjects will be admitted to the clinical site on Day -1 and will be confined until completion of the assessments on Day 9. There will be a washout period of at least 72 hours between doses.
Primary objectives:
- To compare the PK of SMP-100 dissolved in water for oral administration with SMP-100 tablets under fasting conditions, following a single dose in healthy subjects.
- To evaluate the effect of a high-fat, high-calorie meal on the bioavailability of SMP-100 tablets, following a single dose in healthy subjects.
Secondary objective:
• To evaluate the safety and tolerability of two SMP-100 oral formulations when administered to healthy subjects.
