Clinical Trial Designed to Determine the Safety and Efficacy of EMA401 in Patients With Painful Diabetic Neuropathy

August 25, 2015 updated by: Spinifex Pharmaceuticals Pty Ltd

A Double-blind, Placebo-controlled, Randomized Trial to Determine the Safety and Efficacy of EMA401 in Patients With Painful Diabetic Neuropathy

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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.
  • Phase 2

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

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.
  • Have undergone neurolytic or neurosurgical therapy or use a neurostimulating device for PDN.

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.
Outcome Measure
Time Frame
The efficacy of EMA401 compared to placebo in patients with painful diabetic neuropathy (PDN), as assessed by the difference in the weekly mean of the 24 hour average pain score, using an 11-point Numeric Rating Scale (NRS).
Time Frame: Change from Baseline to Week 12
Change from Baseline to Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
