A Double Blind, Placebo and Standard Care Controlled, Randomised Study to Investigate the Clinical Safety and Toleration, Wound Healing and Antiscarring Potential of Two Applications of Intradermal RN1001 (Avotermin) in Healthy Male Subjects

A double blind, Placebo (Vehicle) and Standard Care controlled, randomised study to investigate the clinical safety and toleration (including systemic pharmacokinetics), wound healing and antiscarring potential of two applications of intradermal RN1001 in healthy male subjects

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Double blind, randomised, Placebo and Standard Care controlled, single centre study. Each subject served as their own control, i.e. Arm 1 incisions/biopsies randomly received one of two treatments and Arm 2 incisions/biopsies received the same treatments as for Arm 1 but in reverse. The randomisation of the treatment allowed for control of possible positional effects on healing and subsequent scarring. Subjects were initially dosed and wounded (incisions and punch biopsies) on Day 0 and re-dosed on Day 1. On Day 3, Arm 1 incisions and punch biopsies were re-dosed as per Day 0 and excised, and re-dosed again on Day 4. Arm 2 punch biopsies were excised at Day 5 but not re-dosed. Healed incisions/scars on Arm 2 were excised for histological analysis after 12 months and not re-dosed. All subjects, regardless of treatment were treated according to best practices for moist wound healing.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 45 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  • Healthy, non-Afro-Caribbean, male subjects aged 18-45 years inclusive.
  • Weight between 60 and 150kg and a body mass index between 15 - 55 kg/m2.
  • Subjects who have a previous history of surgery or minor injury and who have not developed any evidence of hypertrophic or keloid scar formation

Exclusion Criteria:

  • Subjects who on direct questioning and physical examination have history or evidence of hypertrophic or keloid scarring.
  • Afro-Caribbean subjects are excluded because of the increased susceptibility to hypertrophic and keloid scarring.
  • Subjects with tattoos or previous scars in the areas to be biopsied.
  • Subjects, who on direct questioning and physical examination, have evidence of any past or present clinically significant disease and particularly coagulation disorders, immuno mediated conditions and skin diseases and allergies, such as eczema.
  • Subjects with a history of clinically significant allergies, especially drug hypersensitivity to lignocaine or allergy to the surgical dressings to be used in this study.
  • Subjects with any clinically significant abnormality following review of pre study laboratory data and full physical examination.
  • Subjects who are taking, or have taken, certain prescribed or investigational drug in the three weeks prior to Day 0 and in particular topical or systemic steroids, and anti-coagulant drugs. Certain drugs are not excluded in this trial. These include OTC analgesics including paracetamol and codeine, vitamin and mineral supplements, inhaled salbutamol, thyroxine replacement therapy, OTC cold remedies.
  • Subjects who drink more than 28 units of alcohol per week (1 unit = ½ pint of beer (285mls) or 25ml of spirits or 1 glass of wine).
  • Subjects who have current evidence of drug abuse.
  • Subjects who are known to have or had serum hepatitis or who are carriers of the hepatitis B surface antigen or hepatitis C antibody. Subjects with previous vaccination against Hepatitis B are not excluded per se.
  • Subjects who are known to have or had serum hepatitis or who are carriers of the hepatitis B core antibody and who show less than 10 units per litre of Anti-HBs.
  • Subjects who have previously had a positive result to the test for HIV 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 study for what ever reason.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
