- Subject answers 'yes' to the question regarding the presence of residual EF over the past 3 months: 'At home over the past 3 months, have you experienced at least some growth of your penis in response to: (1) mechanical stimulation by yourself or your partner, or (2) visual stimulation?'
- Subject has been involved in a continuous heterosexual relationship for at least 6 months prior to screening
- Documented written informed consent from both subject and his female partner
- If the male subject's female partner is of childbearing potential from the time of first sexual intercourse attempt during the screening period until the last administration of study treatment, then the couple must have been using a medically acceptable form of contraception for at least 3 months prior to entering the study, and agree to continue such use for at least 1 month after the last study drug administration. Subjects who are or wish to become pregnant will not be included in the study.
- Subject and his female partner are capable of understanding and complying with the requirements of the protocol and must have signed the ICF prior to participation in any study related procedures
- Low IIEF-EF scores (≤ 25) during the screening period
To continue in the open-label extension phase of the study, subjects must meet the following inclusion criteria at the follow-up visit of the double-blind phase (Visit 6):
- Subject and his female partner complete the double-blind phase
- Subject and his female partner were compliant to study procedures during the double blind phase
- Documented written informed consent from both subject and his female partner
- If the male subject's female partner is of childbearing potential from the time of first sexual intercourse attempt during the screening period until the last administration of study treatment, then the couple must have been using a medically acceptable form of contraception for at least 3 months prior to entering the study, and agree to continue such use for at least 1 month after the last study drug administration. Subjects who are or wish to become pregnant will not be included in the study.
Exclusion Criteria:
- Any significant or serious cardiovascular, pulmonary, hepatic, renal, gastrointestinal, haematological, endocrinological, metabolic, neurological or psychiatric disease which, in the opinion of the PI, renders the subject unfit to take part in the study
- Subject has any history of an unstable medical or psychiatric condition or using any medication that, in the opinion of the PI, is likely to affect the subject's ability to complete the study or precludes the subject's participation in the study Certain concomitant medications; e.g. other vasodilators, calcium channel blockers, angiotensin converting enzyme (ACE) inhibitors, beta blockers, diuretics, anti hypertensives, tricyclic anti depressants and major tranquillisers, as well as the consumption of alcohol, may potentiate the BP lowering effects of MED2005; therefore, the PI must consider this carefully and include subjects at their discretion
- Any presence of a symptomatic, active urinary tract infection diagnosed by the PI or their delegate at screening or during the study
- Any presence of chronic indwelling urethral catheterisation or penile anatomical abnormalities (e.g. penile fibrosis) that would significantly impair EF
- Any history of operations for Peyronie's disease
- Primary hypoactive sexual desire or any history of hypogonadism

- Subjects taking Alpha blockers
- Subjects receiving testosterone pellets
- Any penile surgery except circumcision
- Any treatment with acetyl cysteine within 6 months
- Any treatment with dihydroergotamine within 6 months
- Postural hypotension, hypotension or uncorrected hypovolaemia, as the use of GTN in such states could produce severe hypotension or shock

- Any history of migraine or recurrent headache
- Aortic or mitral stenosis
- Hypertrophic obstructive cardiomyopathy
- Constrictive pericarditis or pericardial tamponade
- Closed-angle glaucoma
- Subjects with nursing partners, known pregnant partners or with partners who wish to become pregnant during the course of the study
- Confirmed positive results from urine drug screen (amphetamines, benzodiazepines, cocaine, cannabinoids, opiates, barbiturates, tricyclic antidepressants and methadone) or from the alcohol breath test at screening (for clarification, any positive result from the urine drug screen or alcohol breath tests at screening will mean the subject will be excluded from the study). In the instance that a subject is using medication which may give a positive result, exclusion will be at the PI's discretion
- Subject has recent (last 12 months) clinical evidence of alcoholism or drug abuse.
- Subject has a positive screen for hepatitis B, consisting of hepatitis B surface antigen (HBsAG), hepatitis C antibody, and human immunodeficiency virus (HIV)
- Any clinically significant abnormal laboratory, vital signs or other safety findings as determined by medical history, physical examination or other evaluations conducted at screening or on admission
- Subjects unwilling to cease use of vacuum devices, intracavernosal injections, PDE-5s or other therapy for ED for the entire course of the study
- Unwillingness of the subject or their partner to agree to make the required attempts at sexual intercourse during treatment period

Subjects are prohibited from participating in the open-label extension phase of the study if they meet any of the following exclusion criteria at the follow-up visit of the double-blind phase (Visit 6):
- Subsequent to recruitment into the double-blind phase of the study, the development of any significant or serious cardiovascular, pulmonary, hepatic, renal, gastrointestinal, haematological, endocrinological, metabolic, neurological or psychiatric disease which, in the opinion of the PI, renders the subject unfit to continue in the open-label extension phase of the study
Subject using any medication that, in the opinion of the PI, is likely to affect the subject's ability to complete or participate in the open-label phase of the study.
NB The concomitant medications listed as exclusion criteria for the study apply to the open-label extension phase. Certain concomitant medications; e.g. other vasodilators, calcium channel blockers, ACE inhibitors, beta blockers, diuretics, anti hypertensives, tricyclic anti depressants and major tranquillisers, as well as the consumption of alcohol, may potentiate the BP lowering effects of MED2005; therefore, the PI must consider this carefully and include subjects at their discretion
- Any presence of a symptomatic, active urinary tract infection diagnosed by the PI or their delegate at the start of the open-label extension phase
- Subsequent to recruitment into the double-blind phase of the study, the development of postural hypotension, hypotension or uncorrected hypovolaemia, increased intracranial pressure or inadequate cerebral circulation, any clinically significant vital signs or other safety findings as determined by medical history, physical examination or other evaluations conducted at Visit 6 prior to recruitment to the open-label phase
