Criteria

Inclusion Criteria:

• Diagnosis of faecal incontinence with a Wexner score of 8 - 20 inclusive at Visit 1 - Screening Visit.

• Historical clinical evidence (past 6 months prior to Visit 1 - Screening Visit) of faecal incontinence episodes (solids, liquid, gas or mucus).

• Greater than or equal to two faecal incontinence episodes (solids, liquid, gas or mucus) per week during the 4 week historical period prior to Visit 1 - Screening Visit.

• Able and willing to receive rectal examinations and treatments.

• Patients must be aged >18 without significant acute or uncontrolled chronic disease.

• Patients must understand the purpose and risks of the study and be able to provide written informed consent and willing, able and competent to complete the entire study and comply with study instructions as defined in the protocol.

• Female patients must be postmenopausal (for at least one year and confirmed by serum FSH at screening), or surgically sterile, practicing true sexual abstinence, or using Investigator-approved methods of contraception throughout the study until after the post study physical examination and have a negative pregnancy test at screening.

• Sexually active male patients must use condoms with their partners throughout the study and for 90 days after completion of the study in addition to their partner's normal mode of contraception.

• Male patients must not donate sperm during the study and for 90 days after the completion of the study.

• Patients taking any continuous medication need to have been on a stable regimen for at least 1 month prior to Visit 1 - Screening Visit.

Exclusion Criteria:

• External anal sphincter disruption related to faecal incontinence caused by trauma.

• Patients with complicating gastrointestinal (GI) disease including those with inflammatory bowel diseases, patients that have received radiotherapy or surgery for anal cancer, patients with rectal prolapse, transanal surgery.

• Relevant history of or presence of any significant or uncontrolled cardiovascular risk including:

1. Systolic > 160mmHg or Diastolic > 100mmHg. Patients on a stable regimen for > 3 months with controlled hypertension prior to Visit 1 - Screening Visit (Systolic < 140mmHg or Diastolic < 90mmHg) can be included.

2. Abnormal 24 hour Screening Holter: corrected QT interval (QTcf) prolongation with cut-off values of >460 ms for females and >430 ms for males, acute arrhythmia, nocturnal bradycardia with heart rate (HR) < 40bpm, atrial fibrillation, AV block Type II and III, Sick Sinus Syndrome, vasovagal syncope.

3. Fixed cardiac output states (severe aortic stenosis (AS), hypertrophic obstructive cardiomyopathy (HOCM).

4. Significant mitral regurgitation (MR).

5. Cardiac failure (New York Heart Association (NYHA) stage II-IV).

• Severe or uncontrolled asthma or chronic obstructive pulmonary disease determined by clinical history, physical examination, lung function tests or exercise tolerance

• Chronic liver disease (e.g. liver cirrhosis, chronic hepatitis, severe hepatic insufficiency).

• Vascular claudication after <50 metres walking distance.

• Severe renal impairment defined as glomerular filtration rate (GFR) ≤ 30 ml/min, uncontrolled and reno-vascular end stage renal disease.

• Patients with diabetic polyneuropathies.

• Any type of chronic diarrhoea or frequent diarrhoea (defined as >5 loose stools per day).

• Faecal impaction and overflow diarrhoea.

• Male patients with clinically diagnosed prostatic hyperplasia.

• Clinically significant electrolyte abnormalities, e.g. clinically significant low/high potassium and low sodium.

• Presence of clinical symptomatic haemorrhoids (grade III and IV), anal fissures or anorectal fistulas.

• Less than 2 episodes of faecal incontinence (solids, liquid, gas or mucus) per week during the 4 week historical period prior to Visit 1 - Screening Visit.

• Participation in a clinical drug study during the 90 days preceding the initial dose in this study.

• Known history of allergy to methoxamine or any other ingredients of the Investigational Medicinal Product.

• Patients who, in the opinion of the Investigator, are unsuitable for participation in the study due to any dependencies, general medical conditions or significant illness within two weeks prior to randomisation.

• Use of any disallowed concomitant medication or other medication that the Investigator believes may affect the study including over-the-counter (OTC) products within 30 days prior to the Investigational Medicinal Product administration.

• A personal or family history of QTcf prolongation or sudden death.

• Patients taking Loperamide (2mg) >8 tablets per day for faecal incontinence either alone or in combination with codeine phosphate and/or paracetamol (8/500mg).

• Patients using any device for the treatment of faecal incontinence.
