Task: Answer Verification
Input (English): Question: Is local interferon-alpha 2b an effective treatment in early-stage Peyronie 's disease?
Answer: IFN-alpha 2b, given according to our regimen, is not useful for the treatment of Peyronie's disease in the early stage since the disease progress continues at different sites in about 25% of the patients, and the side effects are untolerable. Our results also demonstrate that local therapy is not indicated in Peyronie's disease.
Output (English): no
