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.Phase:

Exclusion Criteria:
Part A
Subjects with any of the following will be excluded from study participation:
1. Clinically relevant history of abnormal physical or mental health interfering with the
study as determined by medical history and physical examinations obtained during
screening as judged by the Investigator (including [but not limited to], neurological,
psychiatric, endocrine/diabetic, cardiovascular, respiratory, gastrointestinal,
hepatic, or renal disorder).
2. Clinically relevant abnormal laboratory results (including hepatic and renal panels,
complete blood count, chemistry panel and urinalysis), 12-lead ECG and vital signs, or
physical findings at screening. In case of uncertain or questionable results, tests
performed during screening may be repeated once to confirm eligibility or judged to be
clinically irrelevant for healthy subjects.
3. History or clinical evidence of any disease and/or existence of any surgical or
medical condition which might interfere with the absorption, distribution, metabolism
and excretion (ADME) of the study drugs.
4. Any other concomitant disease or condition that could interfere with, or for which the
treatment might interfere with, the conduct of the study as outlined in this Protocol,
safety of the subject as per the SmPC of KLS and gabapentin (Neurontin 300 mg hard
capsules) or that would, in the opinion of the Investigator, pose an unacceptable risk
to the subject in this study.
5. Subject has a history of neurological disorders which may impact the perception of
pain or impairs the subject's ability to fully participate in the study.
6. Subject has a significant skin allergy, pigmentary disorder, or any active
dermatological condition.
7. AST, ALT, gamma-glutamyl transferase (GGT) or total bilirubin levels above the ULN at
screening. These laboratory evaluations may be repeated once at the discretion of the
Investigator. If the repeat test is within the reference range, the subject may be
included only if the Investigator considers that the previous finding will not
introduce additional risk factors and will not interfere with interpretation of safety
data.
8. Positive test for hepatitis B surface antigen (HBsAg), anti-hepatitis C antibody
(anti- HCV) or human immunodeficiency virus I and II antibodies (anti-HIV I/II) at
screening.
9. Positive urine test for drugs of abuse or alcohol breath test at screening or Day -1
of each treatment period.
10. History of drug and/or alcohol abuse/dependence, or intake of >28 units of alcohol
weekly, and the inability to refrain from alcohol use from 48 hours before screening
and each scheduled visit until discharge from the CRU. One unit is equivalent to a 285
mL glass of full strength beer or 1 (30 mL) measure of spirits or 1 glass (100 mL) of
wine.
11. Habitual and heavy consumption of caffeinated beverages (>8 cups of coffee or
equivalent per day) at screening; and/or unable to refrain from use of (methyl)
xanthine (e.g., coffee, tea, cola, chocolate) from 48 hours prior to dosing until
discharge from the CRU.
12. The subject has participated in a clinical study and has received a medication or a
new chemical entity within 3 months or 5 half-lives (whichever is longer) prior to
dosing of current study medication.
13. Use of any prescription or non-prescription medications, including herbal and
nutritional supplements (including St. John's wort), or OTC medications (e.g.,
ibuprofen, aspirin) within 14 days of dosing and throughout the study. By exception,
the subject may take acetaminophen (less or equal 2 g/day) for up to 48 hours prior to
dosing. The Investigator and study team may review medication on a case-by-case basis
to determine if its use would compromise subject safety or interfere with study
procedures or data interpretation.
14. History of severe adverse reactions or allergies, or history of an anaphylactic
reaction to prescription medications, non-prescription medication, food, NSAIDs or
gabapentin (non-active hay-fever is acceptable).
15. Consumption of any food or drinks containing cranberry, pomegranate, starfruit,
grapefruit, pomelos, exotic citrus fruits or Seville oranges (including marmalade and
juices made from these fruits) within 14 days before admission to the CRU until the
end of the study.
16. Strenuous exercise within 48 hours prior to each blood collection for clinical
laboratory tests.
