Detailed Description
This is a randomised, double blind, cross over clinical study in healthy human volunteers, including pharmacokinetic (PK) sampling and laser Doppler assessment of local blood flow in a subset of up to 6 subjects per cohort, to assess the efficacy and safety of three different topical analgesics (DCF100, TIB200 and SPR300) versus placebo and active control(s) in a model of UV-induced inflammatory pain. The study will consist of 3 cohorts of subjects (n=20 subjects per cohort). Subjects of each cohort will receive test and reference products (no reference product for Cohort 3) of one investigational medicinal product (IMP) and a placebo.
Test Products:
Cohort 1: Ibuprofen, TIB200 gel (10%, w/w) Cohort 2: Diclofenac, DCF100 gel (2% or 4%, w/w) Cohort 3: Methyl-salicylate and Menthol, SPR300 gel (15%:7%, w/w; ratio of Methylsalicylate to Menthol)
Reference Products:
Cohort 1: Ibuprofen, Nurofen Max Strength gel (10%, w/w), Ibuprofen, Nurofen, oral tablet (400 mg) Cohort 2: Voltaren Emulgel (2%), Voltarol oral tablet (50 mg)
Placebo:
All Cohorts:Test product matching vehicle gel.
Pharmacodynamic tests and PK blood draws will be performed at: pre-dose, 1, 2, 4, and 6 hours post dose for all treatment cohorts and treatment days (PK blood sampling in up to 6 subjects per cohort only).
Safety will be evaluated by the incidence of local and systemic treatment-emergent adverse events (TEAEs) reported after each treatment. Safety assessments will also include vital signs, 12-Lead Electrocardiograms (ECGs), laboratory tests and a physical examination at Screening and the Follow-up visit.

Exclusion Criteria:

- Inability to give reproducible HPPT ratings on naïve skin at screening, (defined as HPTT test re-test difference ≥1.0 °C)
- Heat pain perception threshold <40°C or >51°C on naïve skin at Screening.
- Supine systolic blood pressure (SBP) <90 mmHg or >140 mmHg, or supine diastolic blood pressure (DBP) <50 mmHg or >90 mmHg after 5 minutes supine, at the Screening Visit.
- Positive test results for HBsAg, HCVAb or HIV-1 and/or -2 antibodies at Screening.
- Excessive use of caffeine-containing beverages exceeding 500 mg caffeine/day (5 cups of coffee) and the inability to refrain from the use of caffeine-containing beverages during confinement in the Clinical Unit.
- Excessive alcohol consumption (regular alcohol intake ≥21 units per week). Use of alcohol 48 hours before any study visit, as confirmed by urine alcohol testing at Screening, Day -2, and with any additional tests at the discretion of the PI.
- History in the last year or presence of drug addiction (positive urine drug screen) at Screening and Day -2.
- Presence or history of alcohol abuse in the last year, as confirmed by subject's general practitioner (GP).
- Blood donation within 8 weeks before the first IMP administration.
- Participation in another study with an experimental drug within 3 months before the first dosing day.
- Any psychological, emotional problems, any disorder or resultant therapy that was likely to invalidate informed consent, or limited the ability of the subject to comply with the protocol requirements.
- Unlikely to comply with the protocol requirements, instructions and study-related restrictions; e.g., uncooperative attitude, inability to return for Follow-up visits and improbability of completing the clinical study.
- Planned surgery, dental procedure, or hospitalisation from the Screening Visit until the end of the study.
