Study summary

This is a Phase 3 multi-center, randomized, double-blind, vehicle-controlled, parallel group study to be conducted in up to approximately 340 subjects ≥6 months of age with MC. Subjects or their caregivers will apply SB206 12% or Vehicle Gel once daily for a minimum of 4 weeks and up to 12 weeks to all lesions identified at Baseline and new treatable lesions that arise during the course of the study.

Read the detailed description

This is a Phase 3 multi-center, randomized, double-blind, vehicle-controlled, parallel group study to be conducted in approximately 340 subjects with MC. After obtaining informed consent/assent, subjects who satisfy entry criteria will be randomized 2:1 (active:vehicle). Subjects receiving current treatment for MC at the time of the Screening Visit will enter a wash out period of up to 14 days prior to randomization.

Subjects or their caregivers will apply SB206 12% or Vehicle Gel once daily for a minimum of 4 weeks and up to 12 weeks to all lesions identified at Baseline and new treatable lesions that arise during the course of the study. Subjects or their caregivers will continue to treat the area until the next scheduled visit even if the lesion(s) clear. If the investigator determines all lesions are cleared at a clinic visit, the treatment may stop. Subjects will visit the clinic at Screening/Baseline, Week 2, Week 4, Week 8, Week 12. In addition, subjects will be seen in the clinic for a safety follow-up at Week 24.

  • Have between 3 and 70 treatable MC at Baseline;
  • Female subjects age 9 and above must have a negative UPT at Baseline;
  • Female subjects age 9 and above must agree to practice a medically acceptable form of during the study and for 30 days after Week 12/ET1;
  • Be willing and able to follow study instructions and likely to complete all study requirements.

Exclusion criteria

Exclusion Criteria:

  • Have strongly suggested sexually transmitted MC and do not agree to refrain from sexual activities throughout the study period.
  • Are , have immunodeficiency disorder, or are on immunosuppressive treatment;
  • Have significant injury on and/or surrounding MC that may impact ability to treat and count lesions;
  • Have received treatment with topical calcineurin inhibitors or on MC or within 2 cm of MC lesions within 14 days prior to Baseline;
  • Have received treatment for MC during the 14 days prior to Baseline with podophyllotoxin, imiquimod, cantharidin, sinecatechins, topical retinoids, oral or topical zinc, or other homeopathic or over the counter (OTC) products including, but not limited to, ZymaDerm and tea tree oil, cimetidine and other histamine H2 receptor antagonists (including Zantac);
  • Have received surgical procedures related to MC (cryotherapy, curettage, other) within 14 days prior to Baseline;
  • Have MC only in periocular area;
  • Female subjects who are pregnant, planning a pregnancy or breastfeeding;

  • Have more than 1 family member currently participating in a study with a berdazimer sodium product (SB204, SB206, SB208, SB414).
  • Have participated in any other trial of an interventional drug or device within 14 days or concurrent participation in another interventional research study.
  • History or presence of medical, psychiatric, or emotional condition that, in opinion of the investigator, would compromise the safety of the subject or the quality of the data.
Terms in these criteria, in plain language(8)

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.

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.

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.

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

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

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.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

What researchers measure

Primary outcomes

  1. Complete Clearance of All Treatable MC at Week 12

    Percent (proportion) of subjects with complete clearance of all treatable MC at Week 12. This was measured by dividing the number of subjects who showed complete clearance by the number in that treatment group (this represents our primary outcome variable).

    Time frame: 12 Weeks

Secondary outcomes

  1. Complete Clearance of All Treatable MC at Week 8

    Percent (proportion) of subjects with complete clearance of all treatable MC at Week 8. This was measured by dividing the number of subjects who showed complete clearance at week 8 by the number in that treatment group (this represents our secondary outcome variable).

    Time frame: 8 Weeks
