| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |

|
| E.2.2 | Secondary objectives of the trial |
| Furthermore, we want to explore a potential mitigation of BoNT/A by UV-B irradiation and /or the ensuing sunburn reaction of the skin. |

| E.3 | Principal inclusion criteria |
Inclusion criteria · Men or women, aged between 19 and 75 years · Body mass index between 15th and 85th percentile · Normal findings in the medical history, physical and neurological examination · without dermatological alterations on the upper legs in the area of measurement · no exposure to Botulinum toxin for at least one year
|
|
| E.4 | Principal exclusion criteria |
Any of the following will exclude a subject from the study: · Previously exposed to Botulinum toxin · Regular use of anticholinergic medication especially anhidrotic drugs, aminoglycosid antibiotics, abuse of alcoholic beverages · Participation in a clinical trial in the 2 weeks preceding the study · Symptoms of a clinically relevant illness in the 4 weeks before the first study day · Acute skin diseases on the relevant areas · Contraindications to botulinum toxin A: pregnancy, breast feeding, known allergy or hypersensitivity, myasthenia gravis or Eaton-Lambert-syndrom, myopathies and myotonias.

| E.5 End points |
| E.5.1 | Primary end point(s) |
The main outcome variables will be: 1. for peripheral antihyperalgesic effects: heat pain perception threshold (HPPT) 2. for central antihyperalgesic effects: area of secondary hyperalgesia 3. for anti-inflammatory effects: superficial skin blood flow in the sunburn spots, as assessed with laser Doppler interferometry (LDI) 4. for BoNT/A activity after UV-B irradiation and sunburn: area of anhidrosis as assessed with the iondine starch test (Minor Test).
