A phase I study to assess the safety and activity of topical lovastatin (FP252S) for the prevention of chemotherapy-induced alopecia.

INTRODUCTION: A phase I study was performed to establish the minimum effective dose safety of the topical 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase inhibitor lovastatin (FP252S) in preventing chemotherapy-induced alopecia in cohorts of three patients receiving their first doses of chemotherapy with doxorubicin (eight patients) or taxanes (four patients).
RESULTS: One patient at the first dose level receiving doxorubicin and cyclophosphamide had only grade 1 hair loss at 3 weeks. At dose level 2, one patient on doxorubicin took more than 4 weeks to lose her hair and another on docetaxel retained some hair throughout her chemotherapy. At level 3, one patient had grade 2 hair loss at week 4 and another on docetaxel for 6 cycles showed evidence of hair growth between cycles. There were no grade 3 or 4 toxicities, but at the fourth dose level, no higher concentrations could be formulated. DISCUSSION: Lovastatin was well-tolerated at the maximum concentration achievable but showed little efficacy.
