The number of clinical visits for condylomata acuminata (genital warts) has increased substantially over the last 30 years. Most infections cause benign lesions, but some types can be associated with cancers of the cervix and penis. Interferons (IFN) have shown antiviral properties for these infections and IFN-beta, in particular, has shown a specific cytopathic effect in humans. A total of 124 patients with condylomata acuminata, most of whom had failed previous therapy, were treated intralesionally with recombinant human interferon-beta-la (r-hIFN-beta-1a) or placebo.

Up to 6 lesions were treated in each patient and injections were performed 3 times per week for a total of 9 injections. Then the patients were followed for 3 months. Efficacy evaluations at all time points (day 19, week 6, and month 3) showed a clear advantage for interferon-beta r-hIFN-beta-1a treatment. Patients who received r-hIFN-beta-1a showed a higher rate of treatment success in terms of complete or partial reduction (at least 50%) of the total area of ​​the treated lesions. The treatment was also well-tolerated.

Headache, flu-like symptoms, and asthenia were more common in patients receiving r-hIFN-beta-1a, but these adverse events were generally mild in severity and rarely led to patient withdrawal. . It was concluded that r-hIFN-beta-1a has good efficacy in condylomata acuminata and, therefore, presents a useful therapeutic alternative in this difficult-to-treat condition.
