Study summary

Ranpirnase in topical formulation is an antiviral drug being evaluated for the topical treatment of anogenital warts. The aims of this study is to evaluate the efficacy and safety of a topical formulation of ranpirnase in subjects with genital warts.

Read the detailed description

The study consists of the evaluation of 4 weeks exposure to the study product; designed as randomized, double blinded, against vehicle to study the effects of 1 mg/ml concentration of ranpirnase on anogenital warts.

The dermal reaction are scored on a scale that describes the amount of erythema, edema, and other features indicative of irritation.

The clinical response are be scored on the basis of the percentage of the reduction of the lesions in size and number.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Diagnosis of external genital / perianal warts with at least 2 warts and no more than 30 lesions
  • Accept to follow study instructions / signature of IC
  • Abstain from sexual intercourse for 6 hours after applying the study product during the time of the study.

Exclusion criteria

Exclusion Criteria:

  • Any topical and/or destructive treatments for external genital warts within 4 weeks (within 12 months for imiquimod and within 12 weeks for sinecatechins) prior to enrollment (i.e., the randomization visit)
  • Non pregnant. For women in reproductive age it would be required pregnancy test, and the use of double barrier .
  • Any of the following conditions:
  • Known allergy to the study product
  • Internal (rectal, urethral) warts that required or were undergoing treatment;
  • A dermatological disease (e.g., psoriasis) or skin condition in the area, which may interfere with the evaluation.
  • Imiquimod 5% cream (Aldara®)
  • Any marketed or HPV vaccines
  • Sinecatechins (Veregen)
  • Interferon or interferon inducers
  • Cytotoxic drugs
  • Immunomodulators or immunosuppressives
  • Oral or parenteral (inhaled/intranasal steroids are permitted)
  • Oral antiviral drugs (with the exception of HAART, oral acyclovir and acyclovir related drugs) for suppressive or acute therapy herpes; or oseltamivir for prophylaxis or for influenza)
  • Topical antiviral drugs (including topical acyclovir and acyclovir related drugs) in the areas under treatment
  • Podophyllotoxin/Podofilox in the treatment areas
  • Any topical prescription medications in the treatment areas
  • Dermatologic procedures or surgery in the treatment areas
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 6, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
