A Study on Ketoprofen Lysine Salt (KLS) + Gabapentin (GABA) vs KLS to Investigate Their Pharmacodynamic in Healthy Males
brief summary
Part A The primary objective of this study is to determine the single dose pharmacokinetics (PK) of ketoprofen lysine salt combined with gabapentin (KLS-GABA \[80 mg-34 mg\]) compared to KLS alone (80 mg) in healthy male subjects. The secondary objective of this study is: • To determine the safety and tolerability of a single oral dose of KLS-GABA (80 mg-34 mg) compared to KLS alone (80 mg) in healthy male subjects. Part B The primary objective of this study is to determine the pharmacodynamic (PD) effects of KLS-GABA in the Intradermal (ID) capsaicin model in healthy male subjects. The secondary objectives of this study are: * To further investigate the safety, tolerability, and PK of single oral doses of KLS-GABA and KLS alone. * To investigate the possible relationship between plasma levels of drug and efficacy in pain reduction.
detailed description
This is a Phase I, Double-Blind, Pharmacokinetic, Safety and Tolerability Study of Ketoprofen Lysine Salt Combined with Gabapentin (KLS-GABA) Compared to Ketoprofen Lysine Salt (KLS) Alone in Healthy Male Subjects (Part A) Followed by a Randomised, Double-Blind, Placebo-Controlled Study to Investigate the Pharmacodynamic Effects of KLS, and KLS in Combination with Gabapentin (GABA), in Healthy Male Subjects Using the Intradermal (ID) Capsaicin Model (Part B).
Part A is a randomized, double-blind, crossover group study to investigate the safety, tolerability, and PK profile of a single oral dose of KLS-GABA compared to KLS alone in healthy male subjects. It is planned to enroll 12 subjects. All subjects take part in 2 treatment periods, in which they are randomized to receive either a single dose of KLS-GABA (80 mg-34 mg) or a single dose of KLS (80 mg) alone in each treatment period.
Subjects' participation in Part A lasts approximately 7 weeks and will consist of the following:
* A screening visit (up to 28 days prior to Day 1 of Treatment Period 1), * Admission to the clinical research unit (CRU) on Day -1 prior to Treatment Period 1, * Treatment Period 1 (Day 1 to Day 3), * A washout period of a minimum of 7 days, * Admission to the CRU on Day -1 prior to Treatment Period 2, * Treatment Period 2 (Day 1 to Day 3), * A follow-up visit (5 to 7 days post-final dose following Treatment Period 2). Safety will is assessed through Adverse Events (AE) reporting, 12-lead ECGs, vital signs, physical examinations, and clinical laboratory examinations. Pharmacokinetics are assessed by blood sampling.
Part A treatment lasts 2 days (Day 1 in Treatment Period 1; Day 1 in Treatment Period 2)
Part B is a randomized, double-blind, placebo-controlled parallel-group study to investigate the PD effects, PK/PD correlation, safety, and tolerability of three single oral dose levels of KLS-GABA compared to KLS alone, 300 mg gabapentin and placebo in the ID capsaicin model in healthy male subjects.
It is planned to enroll 128 subjects, randomized evenly to 8 possible treatments; subjects receive either KLS alone, KLS-GABA, 300 mg gabapentin or placebo. The planned treatments are:
* KLS alone (40 mg, 80 mg, or 160 mg) * KLS-GABA (40 mg-17 mg, 80 mg-34 mg or 160 mg-68 mg) * Gabapentin (300 mg) * Placebo
Subjects' participation in Part B lasts approximately 6 weeks and consists of the following:
