Study summary

This is a prospective, randomized, open-label, controlled study, aiming to enroll 30 patients with Condylomata Acuminata. The study consists of two phases: a treatment phase (Weeks W1-W12) and an observation phase (Weeks W13-W24). Eligible patients will be randomly allocated into three groups at a ratio of 1:1:1: Test Group 1, Test Group 2, or the Control Group. And clinical cure, recurrence rates, adverse events, vital signs, laboratory tests, drug exposure doses, premature withdrawals will be analyzed.

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

  • Patients must be between 18 and 65 years old.
  • Patients with positive of human papillomavirus(HPV) nucleic acid test and acetowhite test, were diagnosed as condyloma acuminatum according to clinical manifestations and epidemiological history.
  • Patients' lesions are located on non-cavity areas such as the foreskin, glans penis, labia majora, labia minora, with a number ranging from 1 to 5 individual lesions, and each individual lesion having a diameter less than 1 centimeter.
  • For female participants with reproductive capability, a negative pregnancy test result is mandatory at the screening stage.
  • Participants must volunteer to enroll in the study and be able to understand and sign a written form.

Exclusion criteria

Exclusion Criteria:

  • Pregnant women, breastfeeding mothers, or individuals planning to conceive during the study period.
  • Patients who received treatment for genital warts within two weeks prior to screening.
  • Patients with concurrent skin conditions in the affected area that might significantly impact the evaluation of treatment efficacy.
  • Individuals with known severe immunodeficiency or those requiring long-term use of and agents.
  • Active carriers of virus, virus, (HIV), or Treponema pallidum (syphilis).
  • Patients with a history of severe cardiovascular, hepatic, renal, endocrine, digestive, immune, respiratory, or nervous system diseases.
  • Patients with severe retinal disorders or other serious ophthalmologic conditions.
  • Patients allergic to interferons or in the medication formulation, or those deemed unsuitable for CO2 laser treatment.
  • Individuals meeting any listed in the drug's package insert.
  • Patients who participated in another interventional clinical trial within three months before screening, or those planning to participate in another clinical trial during the study period.
  • Other cases deemed inappropriate for enrollment by the investigator due to various reasons.
Terms in these criteria, in plain language(9)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

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.

    Other: CO2 laser

Interventions

  • Participants receive CO2 laser treatment followed by local injection of 36mcg of Peginterferon α-2b directly into the base of each treated wart, repeated weekly for 12 weeks, and then followed for another 12 weeks.

  • Participants undergo CO2 laser treatment and then receive a weekly subcutaneous injection of 180mcg of Peginterferon α-2b for 12 weeks, and then followed for another 12 weeks.

  • OtherCO2 laser

    On the day (baseline), CO2 laser treatment was performed to remove all warts, and the treatment range was 0.2cm around the lesion and the depth was up to the dermis. Wound disinfection after laser. Participants are treated with CO2 laser therapy only and are observed for 12 weeks, followed by another 12-week observation period without any additional adjuvant therapy.
