Becaplermin (recombinant human platelet-derived growth factor-BB [BB homodimer, rhPDGF-BB]) has demonstrated a favorable safety profile in a series of nonclinical studies designed to assess its systemic toxicity, sensitization, local irritation, and genotoxic potential. No significant local or systemic toxicity directly attributable to becaplermin was observed following single and multiple intravenous or subcutaneous administration at doses up to 3 mg/kg in monkeys. Administration of single large intravenous doses (up to 100 mg/kg) and repeated dosing at 1 or 3 mg/kg in mice resulted in rapidly reversible vasodilation and central nervous system depression. In a bone-toxicity study, becaplermin produced histomorphologic changes suggestive of accelerated bone remodeling, which were judged to be potentially reversible. Similar findings have not been observed in humans. Although becaplermin was not considered a dermal or ocular irritant, some skin-sensitizing effects were observed in animals; this finding was not unexpected for a recombinant human-derived protein. Becaplermin was not genotoxic in a variety of in vitro assays and in one in vivo assay. |
