Inclusion criteria

  1. The subject must have completed PellePharm Study Pelle-926-201 or Pelle-926-301.
  2. Study Pelle-926-301 subjects must have completed the End of Treatment Visit in Study 301, prior to the Screening Visit in this study. They must also complete all Study 301 related procedures prior to the Baseline Visit of this study.
  3. The subject must be willing to abstain from application of a non-study topical medication (prescription or over the counter) to facial skin for the duration of the trial except as prescribed by the Investigator. Moisturizers and emollients are allowed. Subjects will be encouraged to use their preferred sunscreen with a sunscreen protection factor (SPF) of at least 30 daily on all exposed skin sites.
  4. Female subjects must have a negative pregnancy test. For Study 301 subjects a negative serum pregnancy test result from Study 301 is acceptable if the test was done within 7 days of the Screening Visit of this study.
  5. If the subject is a woman of child bearing potential (), she must be willing to use methods which may be considered highly effective. Hormonal contraception must be supplemented with a barrier method (preferably condom). Birth control must start prior to Baseline, continue through the duration of the study, and for 30 days after last application of product (IP).
  6. If the subject is a male with a female sex partner who is a WOCBP, the subject must be willing to use condoms, even after a vasectomy, starting prior to Baseline, through the duration of the study, and for at least 3 months after the last application of IP.
  7. The subject is willing for all facial BCCs to be evaluated and follow treatment recommendations made only by the Investigator.
  8. The subject is willing to forego treatment of facial BCCs with anything other than the study IP except when the Investigator believes that delay of treatment of a BCC potentially might compromise the health of the subject. In such instances, the only other allowed form of treatment is surgical.

Exclusion criteria

Exclusion Criteria:

  1. The subject has used topical treatment to the face or systemic therapies that might interfere with the evaluation of the study IP.
  2. The subject has current, recent (within five half lives of the experimental drug or if half life not known, within the past 6 months prior to the Screening Visit), or planned (while enrolled in this study) participation in an experimental drug study (excluding Study 301).
  3. The subject is a who is unwilling or unable to comply with pregnancy prevention measures.
  4. The subject is pregnant or breastfeeding.
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.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

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.

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 Sep 24, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
