Study summary

This trial will investigate whether four doses of RN1001 (20ng, 50ng, 100ng and 200ng) are efficacious in preventing or reducing the resultant scar, as compared to placebo, when applied intradermally to wound margins following excision of benign naevi situated on the head and neck.

Read the detailed description

Male and female subjects (aged between 18-85 years) with one or more benign head \& neck naevi will be invited to participate in the study.

Each patient will be randomised to a particular dose group, depending on the number of naevi suitable for excision. For example, patients with one excised naevi will receive either a dose of one of the concentrations of RN1001, or placebo. A patient with 2 excised naevi will receive an active dose, and placebo. Patients with 3 excised naevi will receive 2 active doses, plus placebo, and patient with four excised naevi will receive 3 active doses plus placebo.

Naevi will be excised using punch biopsy, and then closed with standard sutures. Following wound closure, the study drug (active RN1001 or placebo) will be administered via intradermal injection at a rate of 100ul per linear cm of wound margin.

Digital and film photography will be taken pre-dose and post dose (Day 0, day 14, day 28, Month 2, 3, 6 \& 12, and thereafter at M24, M36, M48 \& M60). Additionally, scar assessments (completed by Investigator, Research Nurse \& Medical photographer) will be completed at follow up visits from Day 20 onwards. Silicone moulds of the scars will be taken at M6, M12 and then annually to M60.

Patients will be requested to complete a questionnaire to rate their scar expectations/assessment on a total of 5 occasions (screening, Day 0, Month 3, Month 6 \& Month 12)

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

  • Weight between 50 and 150kg and a within the permitted range for their height, using Quetelet's index-weight (kg)/height² (m). The permitted index is between 15-55.
  • Subjects with one or more benign head and neck naevi which when measured are at least 3cm apart.
  • Subjects who are aged 18-85 years.

Exclusion criteria

Exclusion Criteria:

  • Subjects who on examination have a naevus or naevi, which appear clinically suspicious of and therefore require specialist referral and treatment.
  • Subjects who on direct questioning and physical examination have a history or evidence of hypertrophic or keloid scarring or tattoo(s) or previous scar(s) in the area to be excised.
  • Subjects with a personal history of a bleeding disorder.
  • Subjects with a skin disorder that is chronic or currently active and which the Investigator considers will adversely affect the healing of acute wounds or involves the areas to be examined in this trial.
  • Subjects with any medical condition that would impair wound healing including renal, hepatic, haematological, neurological or immune disease.
  • Subjects with a history of clinically significant drug to lignocaine or allergy to surgical dressings to be used in this trial.
  • Subjects with any clinically significant abnormality following review of pre trial laboratory data and physical examination.
  • Subjects who are taking, or have taken, any drugs within the last 30 days, long term oral, topical or inhaled therapy and anti coagulant or anti medication.
  • Certain drugs are not excluded in this trial. These include OTC analgesics including paracetamol and codeine, vitamin and mineral supplements and OTC cold remedies containing paracetamol as the active ingredient.
  • Subjects who are pregnant or who become pregnant up to and including Day 0. Subjects must use suitable forms of during at least the first two months of the trial.
  • Subjects who have previously had a positive result to the test for antibodies, or who admit to belonging to a high-risk group.
  • In the opinion of the Investigator, a subject who is not likely to complete the trial for whatever reason.
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.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

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.

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.

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.

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.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

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.

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.

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 Apr 11, 2008, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
