Details and patient eligibility

About

The study consists of two periods, the Screening Period (~3 weeks) and Treatment Period (12 weeks).

Eligibility for the study will be determined by Screening tests, physical examination/medical history, and fulfilment of eligibility criteria including assessment of pain completed during the Screening Period. Potential participants will be required to provide written informed consent prior to any study-specific Screening procedures being performed.

Following Screening assessments, patients will be randomized to receive either EMA401 300 mg BID or placebo.

Patient study visits during the Treatment Period are at the end of baseline/randomization visit, and end of Weeks 3, 6, 9, and 12, for assessments.

Inclusion criteria

Patients with Type I or Type II diabetes mellitus with painful, distal, symmetrical, sensory-motor neuropathy attributed to diabetes, of at least six months duration.
Be assessed as suffering from moderate to severe pain across the Screening Period. The assessment of moderate and severe pain will be made using an algorithm proprietary to Spinifex. The investigator/site staff will be informed immediately as to whether the patient is eligible or ineligible on the ePRO website based on the patient entering all relevant pain scores in the eDiary device.
Women of child bearing potential (WOCBP), must have a negative urine pregnancy test at the Screening visit (Visit 1) and within 72 hours prior to administration of IP.

Exclusion criteria

Patients taking any topical treatment for their PDN at the time of Screening Visit 2 will be excluded, including lidocaine plaster, capsaicin patch, and any other topical preparations of these or any other topical medications (e.g., aspirin, Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) for their PDN.
Have a blood pressure reading, after resting for at least five minutes, outside a systolic blood pressure range of 84 - 151 mmHg or a diastolic blood pressure > 95 mmHg. If the blood pressure is outside of the range, a repeat measurement can be taken after the patient has rested. The repeat measurement should be used as the screening value.
Have serum aspartate transaminase (AST), or alanine transaminase (ALT) levels > 1.5 x the upper limit of normal or have total bilirubin concentrations > 1.5 x the upper limit of normal at Screening (Visit 1).
Have hemoglobin A1c > 11 %.
Known history of, or positive laboratory results for hepatitis B virus (HBV), hepatitis C virus (HCV) or human immunodeficiency virus (HIV) infection as defined by being seropositive for hepatitis B surface antigen (HBsAg), HCV antibodies or HIV antibodies respectively.
