Treatment Group A: Metronidazole 10% w/w ointment. A 2.5 cm strip of ointment (approximately 700 mg) will be administered topically to the wound together with suitable dressing, once daily.

One dose contains approximately 70 mg metronidazole in a formulation of white soft paraffin. The Investigator will demonstrate to the subject how to apply a 2.5 cm of IMP and dress the wound by applying the first dose and covering with a dry, gauze dressing which is to be retained with tape. Larger wounds may require additional amount of IMP to ensure sufficient cover of the wound

Treatment Group B: Placebo ointment. A 2.5 cm strip of ointment (approximately 700 mg) will be administered topically to the wound together with suitable dressing, once daily.

One dose of placebo ointment contains titanium dioxide and white soft paraffin. The Investigator will demonstrate to the subject how to apply a 2.5 cm of IMP and dress the wound by applying the first dose and covering with a dry, gauze dressing which is to be retained with tape. Larger wounds may require additional amount of IMP to ensure sufficient cover of the wound.

Title of Study:

Randomised, double-blind, placebo-controlled trial evaluating the effects of metronidazole ointment in facilitating resolution on non-healing pilonidal sinus wounds Medical Condition Under Investigation Non-healing pilonidal sinus wounds

Study centres: 2 Centres in Turkey

Clinical Phase: Phase 2

Protocol Number: MET-PS-02

Study Design: Randomised, double-blind, placebo-controlled, parallel group study to determine the safety and efficacy of metronidazole ointment applied to the wound, following debridement in non-healing pilonidal sinus wounds.

Planned Sample Size: 80 subjects

Route of Administration: Cutaneous

Investigational product and dosage:

Treatment Group A: Metronidazole 10% w/w ointment. A 2.5 cm strip of ointment (approximately 700 mg) will be administered topically to the wound together with suitable dressing, once daily.

One dose contains approximately 70 mg metronidazole in a formulation of white soft paraffin. The Investigator will demonstrate to the subject how to apply a 2.5 cm of IMP and dress the wound by applying the first dose and covering with a dry, gauze dressing which is to be retained with tape. Larger wounds may require additional amount of IMP to ensure sufficient cover of the wound.

Comparator and dosage:

Treatment Group B: Placebo ointment. A 2.5 cm strip of ointment (approximately 700 mg) will be administered topically to the wound together with suitable dressing, once daily.

One dose of placebo ointment contains titanium dioxide and white soft paraffin. The Investigator will demonstrate to the subject how to apply a 2.5 cm of IMP and dress the wound by applying the first dose and covering with a dry, gauze dressing which is to be retained with tape. Larger wounds may require additional amount of IMP to ensure sufficient cover of the wound.

Maximum Duration of Treatment:

The subject's participation in the study will last 10 weeks (including 2 week screening, 6 weeks clinical phase and 2 week follow-up phase).

Procedures:

Recruitment:

Subjects will be recruited through surgical out-patient clinics who will be contacted directly or through advertisements. Potential Subjects will have the opportunity to read or hear the study advertisement and contact the researcher through the contact details provided. Potential participants will have the opportunity to ask any questions to the researchers.

A member of the research team will then send a copy of the information sheet (either by email or post) or hand to the participant, who will have the opportunity to ask any questions to the researchers, either by email or phone.

Subjects expressing an interest in participating will be interviewed at their scheduled clinic appointment to explain the study in detail, and discuss the risks, benefits, goals and limitations of the study by the treating nurse.

Screening:

Potentially eligible Subjects will provide written informed consent prior to any study specific procedures being conducted.

Following the provision of written, informed consent, the Subject's demography, medical history, especially that relating to pilonidal sinus including details on surgical interventions, will be documented. Female Subjects of child-bearing potential will undergo a urine pregnancy test. Following a physical examination, height, weight and checks on vital signs, the Subjects will have blood samples drawn for routine haematology and biochemistry analyses. Subjects will be asked to provide details of any concomitant medications. The wound will be sized and graded using the Pressure Ulcer Scale for Healing (PUSH) tool 3.0. Subjects will have their wound assessed, then debrided and any surrounding hair removed by shaving, cleaned and dressed in accordance with normal management procedures.

Subjects with a confirmed diagnosis of non-healing pilonidal sinus wound, compliance with the inclusion and exclusion criteria and providing written informed consent will be registered on the electronic case report form (eCRF) to obtain a screening number.

The Investigator will demonstrate to the subject how to clean and dress the wound.

The subject will be educated on the use of the diary and asked to record at the end of each day the number of times they cleaned and dressed the wound and any changes in their condition or concomitant medication. Subjects will be asked to complete the diary over the subsequent 2 weeks.

Subjects not wishing to participate, or who are ineligible, will be followed up in accordance with the clinic's standard management procedures.

Baseline:

The subject will attend the clinic and the diary will be reviewed to ensure completion of the diary, the number of times the wound was cleaned and dressed, any changes in their condition or concomitant medications. Haematology and biochemistry test (from Screening) results will be confirmed as being acceptable.

Subjects will have the status of their pilonidal disease assessed and the wound will be sized and graded using the Pressure Ulcer Scale for Healing (PUSH) tool 3.0, to confirm that it remains unhealed with no improvement.

Subjects demonstrating improvement in the wound and healing in the screening period, will be followed up in accordance with the clinic's standard management procedures.

Female Subjects of child-bearing potential will undergo a pregnancy test. Subjects compliant with the inclusion and exclusion criteria will be randomised on a 1:1 basis to one of the two treatment groups: metronidazole 10%w/w ointment or matching placebo ointment. Randomisation will be stratified by wound size less than 3cm.

Following a physical examination, weight and checks on vital signs, blood samples will be drawn for routine haematology and biochemistry analyses. The wound will be swabbed for microbial analysis, then debrided and any surrounding hair removed by shaving.

The subject will be provided with two pre-weighed tubes of IMP together with a supply of sterile dressings. The Investigator will demonstrate to the subject how to apply 2.5 cm of IMP and dress the wound by applying the first dose and covering with a dry, gauze dressing which is to be retained with tape.

The subject will be retrained on completion of the diary and asked to record each day confirmation of wound cleansing, IMP dose application and wound dressing as well as any changes in their condition or concomitant medication.

Week 1:

One week after randomisation, the subject will be contacted by telephone to check on their progress, compliance with study medication, concomitant medications and the occurrence of any adverse events.

Weeks 2, 4 and 6 :

Two, four and six weeks after randomisation, the subject will attend the clinic for review of the healing status of their pilonidal disease including sizing of the wound and assignment of a PUSH score, together with checks on vital signs and a physical examination. In addition, the subject will complete the PGI I in relation to their pilonidal disease, relative to the baseline condition.

Haematology and biochemistry test (from Baseline) results will be confirmed as being acceptable (Week 2 Visit only).

At each visit the IMP tubes will be weighed to determine the amount used as a check on compliance with study treatment. The subject diary will be reviewed and any changes in symptoms and concomitant medications registered in the eCRF.

The Investigator will clean the wound and remove any surrounding hair by shaving. During each visit apply the dose of IMP and dress the wound for that day (Week 2 and Week 4 Visits only).

At the Week 6 visit, subjects will also provide blood samples for routine haematology and biochemistry analyses. Female subjects of child-bearing potential will undergo a pregnancy test. Subjects considered a clinical failure will have the pilonidal sinus wound swabbed for microbiological analysis.

In the event that the wound is judged to be completely healed at any visit, the subject will be instructed to stop applying the study medication. The Week 6 procedures will be performed and the subject will be asked to attend the clinic after a further 2 weeks, when the Week 8 procedures will be undertaken.

In the event that a subject wishes to withdraw prior to the end of the study, they will be asked to undertake the Week 6 procedures.

For subjects who have failed to heal, appropriate post-study treatment will be instituted.

Week 8 (follow-up):

Eight weeks after randomisation (or two weeks after a visit at which complete healing is confirmed), the subject will attend the clinic for review of the healing status of the pilonidal disease including wound size and PUSH score, together with checks on vital signs, changes in symptoms and concomitant medications. The subject will complete the PGI I in relation to their pilonidal disease, relative to the baseline condition. Haematology and biochemistry test (from Week 6 Visit) results will be confirmed as being acceptable.

Blood and urine sampling:

A blood sample will be drawn at the Screening, Baseline and Week 6 Visits for routine haematology and biochemistry tests.

Urine pregnancy tests will be conducted at Screening, Baseline and Week 6 Visits.

Safety Parameters:

Study subjects will be asked to record any changes in symptoms in the diary provided on a daily basis. This will be reviewed at each study visit and any adverse events will be documented in the eCRF. Changes in vital signs and outcome of routine blood analyses will be evaluated.

Adverse events (AEs) will be classified using a coding thesaurus (MedDRA).

Primary Endpoint:

Complete wound healing by Week 6.

Secondary Endpoints:

* Rate of wound healing \[(baseline mm3 - Current mm3) / baseline mm3 x 100%
* Proportion of subjects with complete healing by Week 2 and 4
* Proportion of subjects with complete healing maintained over two consecutive visits
* Time to response, defined as complete healing
* Change from baseline in PUSH score at Weeks 2, 4 and 6
* Patient's Global Impression of Improvement (PGI-I) at Weeks 2, 4 and 6

Safety Endpoints:

The safety analysis will be conducted in all randomised subjects receiving at least one dose.

* Number and proportion of subjects with adverse events.
* Assessment of clinical laboratory parameters.
* Assessment of vital signs.

Statistical Analyses:

Proportion of subjects with complete healing and with partial healing will be presented using point estimates with 95% confidence intervals.

Differences in the rates of healing will be determined by difference in the mean. SE of the mean and 95% confidence interval will be reported.

Time to response will be presented in Kaplan-Meier curves. PUSH score will be presented by using point estimates with 95% confidence intervals. Comparisons between each treatment and placebo will be based on an Analysis of covariance (ANCOVA) model.

PGI-I will be presented by category using point estimates with 95% confidence intervals. Comparisons between each treatment and placebo will be based on a proportional odds model.

AEs will be classified into standard terminology using a coding thesaurus (MedDRA). Treatment-related AEs will be summarised separately from all AEs. In addition, the maximum intensity of AEs will be summarised. For AEs these will be summarized using descriptive statistics. Results of laboratory tests and measures of vital signs will be presented as summary statistics and as shift tables.

Missing data will be handled using a worst observation carried forward (WOCF) imputation. Sensitivity analyses will be included in the SAP.
