About this study
Official title: An Open-label, Multi-center, Dose-escalation, Cohort Study to Determine the Maximum Tolerated Dose and Safety of PEP005 Topical Gel Given as Either a Single Application (on Day 1) or as Two Applications (on Day 1 and Day 8) to a Superficial Basal Cell Carcinoma (sBCC) on the Trunk.
The purpose of this study is to determine maximum tolerated dose level (MTD) of PEP005 Topical Gel for the treatment of superficial basal cell carcinoma on the trunk
Read the detailed description
Basal cell carcinomas (BCCs) are a common skin problem largely caused by long term sun exposure. Current treatments include surgery, curettage/desiccation and simple excision, which are often cosmetically disfiguring. Non-invasive alternative therapy for treatment of BCC lesions is thus being researched. Sap from the plant Euphorbia peplus has been used for many years in Australia as a "folk" remedy to treat a number of skin conditions. The active component of Euphorbia peplus has been isolated and made into a gel applied directly to the skin by Peplin Opeation Pty Ltd.
The proposed study follows a previously conducted 12 week study in sBCC, PEP005-003. This was a two dose schedule evaluating doses up to 0.05%. Histological clearance rate at the end of study was 71% for the 0.05% concentration on the Day 1, Day 2 schedule compared with 0% in the vehicle group.
The proposed study aims to determine the maximum tolerated dose level (MTD) of PEP005 Topical Gel, in patients, when administered either as a single application or as two applications to a selected superficial basal cell carcinoma lesion with a 3 month follow up.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing PEP005 in people with Superficial Basal Cell Carcinoma, run by Peplin at 9 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Maximum Tolerated Dose level (MTD) through incidence of treatment related AEs, local skin reactions and pigmentation and scarring. (time frame: 85 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00432185, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Feb 2016; AzTrials last refreshed its copy on 7 Nov 2026.
