The main objective of this study is to assess the relative systemic bioavailability of
diclofenac in the presence and absence of capsaicin by comparing the systemic bioavailability
of diclofenac from a combination product (Diclofenac 2% + Capsaicin 0.075% Topical Gel) with
two diclofenac only products, Diclofenac Mono Gel 2% and Voltarol® 12 Hour Emulgel 2.32% Gel,
following topical administration.
In order to examine potential racial differences in pharmacokinetics (PK), the study
population will be stratified 50:50, Caucasian versus Black people. With respect to the main
objective, additionally a supportive analysis will be performed to investigate the influence
of race on the intra-individual bioavailability ratios.

Eligibility |
Inclusion Criteria: - Healthy males and females, 18 to 50 years (inclusive) at time of screening. - Body mass index (BMI) between 18.5 and 29.9 kg/m2 (inclusive). - Body mass not less than 50 kg for males and females. - Findings for medical history, vital signs, physical examination, standard 12-lead electrocardiogram (ECG) and laboratory investigations must be normal or within laboratory reference ranges for the relevant laboratory tests, unless the PI considers the deviation to be not clinically significant for the purpose of the study. - Non-smokers. - Females, if: - Not of childbearing potential, - Of childbearing potential, the following conditions are to be met: - Negative pregnancy test. - Not lactating. - Abstaining from sexual activity (if this is the usual lifestyle of the subject) or must agree to use an accepted method of contraception, and agree to continue with the same method throughout the study. - Written informed consent given for participation in the study. - Further inclusion criteria apply. Exclusion Criteria: - Evidence of psychiatric disorder, antagonistic personality, poor motivation, emotional or intellectual problems likely to limit the validity of consent to participate in the study or limit the ability to comply with protocol requirements. - Current alcohol use > 21 units of alcohol per week for males and > 14 units of alcohol per week for females. One unit (10 g alcohol) is equal to beer (330 mL), wine (200 mL), or distilled spirits (25 mL) per day. - Regular exposure to substances of abuse (other than alcohol) within the past year. - Use of any medication, prescribed or over-the-counter (especially products containing diclofenac or use of other oral nonsteroidal anti-inflammatory drugs [NSAIDS]) or herbal remedies, within 2 weeks before the first administration of Investigational medicinal product (IMP) except if this will not affect the outcome of the study in the opinion of the PI (Principal Investigator) (in collaboration with the Sponsor). In this study the concomitant use of hormonal contraceptives is allowed. - Participation in another study with an experimental drug, where the last administration of the previous IMP was within 8 weeks (or within 5 elimination half-lives for chemical entities or 2 elimination half-lives for anti-bodies or insulin), whichever is the longer before administration of IMP in this study, at the discretion of the PI. - Treatment within the previous 3 months before the first administration of IMP with any drug with a well-defined potential for adversely affecting a major organ or system. - A major illness during the 3 months before commencement of the screening period. - History of hypersensitivity or allergy (acute rhinitis, angioedema, urticaria or bronchial asthma) to the IMP or its excipients or any related medication (Aspirin or any other NSAID). - History of hypersensitivity or allergy to cayenne pepper or other capsaicinoids (paprika plants). - History of bronchospasm or bronchial asthma, arterial hypertension, myocardial infarction, thrombotic events, stroke, congestive heart failure, impaired renal function or liver disease. - History or current diagnosis of gastrointestinal bleeding or peptic ulcer disease. - Relevant history or laboratory or clinical findings indicative of acute or chronic disease, likely to influence study outcome. - Donation or loss of blood equal to or exceeding 500 mL during the 8 weeks before the first administration of IMP (Investigational medicinal product) . - Bruises, damaged skin, eczema or wounds on the application site, or the application site inappropriate for applying the IMP in the opinion of the PI (Principal Investigator). - Further exclusion criteria apply. |

Primary | Area Under the Plasma Concentration-time Curve (AUC) Over One Dosing Interval for Diclofenac at Steady State (AUC0-t,ss) (t = 12 Hours) (Day 7) | AUC0-t,ss, Area under the plasma concentration-time curve (AUC) over one dosing interval at steady state for diclofenac at day 7 (t = 12 hours). Stratification by race was analysed using a supportive Analysis of Variance (ANOVA) yielding point estimates for each underlying pairwise comparison analog to the main analysis. As the resulting two Least Square Means and Geometric Means (gMeans) per treatment and race are very similar, only gMeans per treatment and race are presented. | Pharmacokinetic samples were collected on Day 7 at pre-dose and 0.5, 1, 2, 3, 4, 6, 8, 10 and 12 hours after the drug administration | |
Primary | Maximum Plasma Concentration During a Dosage Interval (Cmax,ss) Obtained Directly From the Concentration-time Data for Diclofenac at Steady State (Day 7) | Cmax,ss, Maximum plasma of diclofenac concentration during a dosage interval obtained directly from the concentration-time data at steady state for diclofenac on day 7. Stratification by race was analysed using a supportive Analysis of Variance (ANOVA) yielding point estimates for each underlying pairwise comparison analog to the main analysis. As the resulting two Least Square Means and gMeans per treatment and race are very similar, only gMeans per treatment and race are presented. | Pharmacokinetic samples were collected on Day 7 at pre-dose and 0.5, 1, 2, 3, 4, 6, 8, 10 and 12 hours after the drug administration | |
Secondary | Time to Maximum Observed Plasma Concentration at Steady State for Diclofenac at Steady State (Tmax,ss) (Day 7) | tmax,ss, Time to maximum observed plasma concentration at steady state for diclofenac at day 7 (tmax,ss). Descriptive statistics by race are reported in addition. | Pharmacokinetic samples were collected on Day 7 at pre-dose and 0.5, 1, 2, 3, 4, 6, 8, 10 and 12 hours after the drug administration | |
Secondary | Average Plasma Concentration (Cav,ss) for Diclofenac at Steady State | Average plasma concentration (Cav,ss) calculated as AUC0-t,ss divided by t=12 hours (t is the duration of the dosing interval). Descriptive statistics by race are reported in addition. | Pharmacokinetic samples were collected on Day 7 at pre-dose and 0.5, 1, 2, 3, 4, 6, 8, 10 and 12 hours after the drug administration | |
Secondary | Percentage Peak-trough Fluctuation (%PTF), Calculated as [100*(Cmax,ss - Cpre,ss)/Cav,ss] | Percentage peak-trough fluctuation (%PTF) which was calculated as [100*(Cmax,ss - Cpre,ss)/Cav,ss] for Diclofenac. Descriptive statistics by race are reported in addition. | Pharmacokinetic samples were collected on Day 7 at pre-dose and 0.5, 1, 2, 3, 4, 6, 8, 10 and 12 hours after the drug administration |
