Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the results of the study, there was no evidene of skin sensitization following treatment with the test article.
- Executive summary:
The dermal sensitization potential of the test article was evaluated in the Maximization Test using male and female Hartley guinea pigs. This study was performed in accordance with GLP (1997). The study design was based on Maximization Test methods described in Dermatotoxicology, 5 ed. (1996). The test article was prepared in Sterile Water for Injection (vehicle for intradermal induction) or petroleum jelly (vehicle for epidermal induction and challenge) just prior to each dosing procedure. The test group (10 males and 20 females) received intradermal induction injections of 0.1 ml/site of a 1:1 mixture of Freund’s Complete Adjuvant (FCA):vehicle, 125 mg/mL test article in vehicle, and 125 mg/mL test article in 1:1 FCA/vehicle. A control group (5 males and 10 females) received the same induction treatment with the exclusion of test article. The epidermal induction of sensitization was conducted under occlusion with 0.5 g test article in vehicle (test group) one week after the intradermal induction and 24 hours after pre-treatment with 10% sodium dodecyl sulfate. The control group did not receive any treatment during the epidermal induction. Two weeks after epidermal induction the control and test animals were challenged by epidermal application of 33.33% test article and vehicle only under occlusive dressing. Skin reactions were evaluated at 24 and 48 hours after removal of the dressing. One week after the first challenge, the males were rechallenged in a similar manner. The females were not rechallenged due to a lack of positive results. Positive controls (2-mercaptobenzothiazole and hexyl cinnamic aldehyde) were recently tested to confirm the validity of the experimental technique. Three control group males and one test group male were found dead on Days 9-11. These deaths were not associated with test article treatment. No erythema or edema was observed at any site in either the control or test article group females following the first challenge. No erythema or edema was observed at any site in either the control or test article group males following the rechallenge (0% responders). Based on the results this study, there was no evidence of skin sensitization following treatment with the test article.
