CyPep-1 in Cutaneous Warts

• Status: Completed
• Trial end date: 2019-12-20
• Target enrollment: 0
• Participant gender: All

Summary

This Phase 1 study is intended to explore the safety, tolerability, pharmacodynamics and efficacy of topical CyPep-1 as a potential treatment for HPV-associated conditions. Since this is a first-on-human study of a topical formulation, the first subjects will be monitored more frequently in order to establish the safety profile. Because clinical outcomes (i.e. reduction/clearance of the lesion) often require lengthy treatment / observation periods, the study design will primarily utilize clinical measurements of wart dimensions, along with HPV viral load as a biomarker of anti-viral effect.

• Agree not to use wart-removing products (prescription or over-the-counter) in the target area or prohibited medications other than the study medication during the course of the study.

Exclusion Criteria:

• Any clinically significant abnormality as determined by medical history taking and physical examinations obtained during the screening visit that in the opinion of the investigator would interfere with the study objectives or compromise subject safety;

• Not willing to use effective (double barrier) contraception until at least 3 months after last study drug application;

• For women: a positive pregnancy test and/or breastfeeding at screening or women who plan to become pregnant;

• Have used salicylic acid or any other over-the-counter wart-removing product including cryotherapy in the treatment area within 28 days prior to first study drug application;

• Have required systemic intake of immunosuppressive or immunomodulatory medication (including oral or parenteral corticosteroids) within 60 days prior to first study drug application or during the course of the study. Routine use of inhaled or intranasal corticosteroids during the study is allowed;

• Have any current and / or recurrent clinical significant skin infection in the treatment area other than common warts;

• Have a known sensitivity to any of the investigational product ingredients;

• Participation in an investigational drug or device study within 3 months prior to screening or more than 4 times in the past year;

• Donation of blood or blood loss of >500 mL within 3 months prior to screening or donation of plasma within 14 days

• Not having a general practitioner;

• Not willing to give permission to have the general practitioner to be notified upon participation in this study;

• Any condition that in the opinion of the investigator would complicate or compromise the study or the well-being of the subject.

Part 2 only:

• Have treatment resistant / persistent warts as defined as one of the following:

1. More than 5 different failed treatments including topical formulations and cryotherapy

2. Longer than 6 years presence of the target wart

3. Having received active treatment in a clinical trial with an experimental drug for cutaneous warts.
