Brief Summary

The purpose of this study is to determine the safety and local toleration and histological effects of various dose levels of avotermin (Juvista) injected intradermally in healthy male volunteers.

Detailed Description

The study was split into two Cohorts: A and B. Volunteers in Cohort A were assigned to one of four dose groups receiving 50, 100, 500 and 1000ng/100μl/3mm punch biopsy. Volunteers were assigned sequentially in order of ascending dose. Within each dose group volunteers were further randomised to subgroup a, b or c. Each subject was set to receive four 3mm punch biopsies, two on each arm, and intradermal injection of avotermin, placebo or nothing (standard care).

On day 0 two 3mm punch biopsies were administered under local anaesthesia to the inner aspect of one arm of each subject following intradermal injection of avotermin, placebo or nothing. The four subjects in subgroup a received avotermin to one punch biopsy and placebo to the other. The four subjects in subgroup b received avotermin to one punch biopsy and standard care only to the other. The one subject in subgroup c was administered with intradermal placebo to one biopsy and standard care only to the other. 24 h later a further application of intradermal avotermin, placebo or nothing was applied.

While arm 1 was used as a study arm, arm 2 was used for safety procedures. Subjects were then randomised to return on Day 3 or 7 for excision of the first two punch biopsies. At the same time two punch biopsies and the same treatment regime was carried out on the second arm. These were dosed again 24 h later and all were excised on Day 10.

After determining safety and toleration of all doses in Cohort A, new subjects were assigned to Cohort B. These were allocated in ascending order to groups that would receive 1, 10, 50 and 100μg/100μl/3mm punch biopsy, following the same procedures that were used for Cohort A. Only after the first three groups reached Day 10 and the safety data was analysed would the final volunteers be recruited to the 100μg group.
