A multicenter, Phase 2a, randomized, double-blind, placebo (vehicle)-controlled, parallel-group, dose-finding study designed to evaluate the efficacy, safety and tolerability of NRD135S. E1 in adult patients with diabetes mellitus type 1 or 2 with neuropathic pain. Potential study patients will sign informed consent prior to undergoing any study-related procedure.

Clinical Details

Official title: A Phase 2a, Randomized, Double-blind, Placebo (Vehicle)-Controlled, Dose Finding Trial to Assess the Safety, Tolerability and Efficacy of NRD135S.E1 in Patients With Neuropathic Pain Associated With Diabetes Mellitus

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator), Primary Purpose: Treatment

Primary outcome: • Change from the baseline week to Week 3 in the weekly average daily pain intensity as measured on an 11-point numerical pain scale (NPS)

Secondary outcome:

Change from the baseline week to Week 3 in the weekly maximum daily pain intensity as measured on the NPS

Change from the baseline week to Week 3 in the weekly consumption of rescue analgesic (i.e., number of paracetamol 500 mg tablets taken per week)

• Change from Day 8 (end of baseline week) to Day 29 (24 h after last study drug administration) in Short-Form McGill Pain Questionnaire (SF-MPQ) score

Clinician's Global Impression of Change from the baseline week at Day 29 (24 h after last study drug administration)

Patient's Global Impression of Change from the baseline week at Day 29 (24 h after last study drug administration)

Change from the baseline week to Week 3 in the weekly Daily Sleep Interference Score

Incidence of treatment-emergent AEs (TEAEs)

Detailed description: Following screening, eligible patients will be enrolled and go through a week of washout of analgesic treatment. Patients who are still eligible following the washout will be randomized to one of four treatment groups: NRD135S. E1 at 10, 40, or 150 mg per day or placebo (vehicle). All four treatment groups will start study treatment with 1 week of single blind placebo (baseline week) followed by 3 weeks of the allocated double blind treatment (Weeks 1, 2, and 3). All patients will be followed for 30 days after the last study drug administration. The total study duration per patient is 9 to10 weeks. Visit schedule: Screening (Days minus 14 to minus 8, Visit 1). Washout visit (Day minus 7, Visit 2). Randomization and start of placebo treatment (Day 1, Visit 3). Double blind treatment visits on Days 8 (Visit 4), 15 (Visit 5) and 29 (Visit 6). Follow up visit by telephone (Day 59, Visit 7).


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.


Inclusion Criteria:

1. - Males agree to use condoms throughout treatment and follow up study periods.

- Females must not be of childbearing potential as evidenced by at least one of

the following: ≥ 62 years old and amenorrheic for ≥ 1 year

- Amenorrheic ≥ 12 consecutive months and a documented serum follicle stimulating

hormone (FSH) level > 35 mIU/mL

- Irregular menstrual periods and a documented FSH level > 35 mIU/mL

- On hormone replacement therapy and prior clinical evidence of menopause based on

any of the criteria above

- Surgically sterile

2. Known stable diabetes mellitus for the last 3 months. (No oral hypoglycemic medications change allowed. Maximum insulin change allowed is ± 20%). 3. Evidence of peripheral neuropathy associated with diabetes mellitus diagnosed by DN4 criteria. 4. Presence of ongoing pain due to DPN for at least 3 months. 5. Mean DPN pain intensity of 4 to 9 on the NPS at screening. 6. HbA1c ≤ 9% of total hemoglobin at screening. 7. Willing to stop pain medications for DPN (except for limited use of paracetamol). 8. Signed written informed consent.

- Subjects must have signed and dated an Institutional Review Board / Independent

Ethics Committee approved written informed consent form in accordance with regulatory and institutional guidelines. This must be obtained before the performance of any protocol related procedures that are not part of normal subject care.

- Subjects must be willing and able to comply with scheduled visits, treatment

schedule, laboratory testing, and other requirements of the study. Exclusion Criteria 1. Female of childbearing potential. 2. Neurologic disorders unrelated to DPN that may interfere with the assessment of DPN. 3. Known allergy or intolerance to paracetamol. 4. Evidence of non-DPN polyneuropathy. 5. The presence of severe pain associated with conditions other than DPN (e. g., peripheral vascular disease, phantom pain, etc.) that could confound the self-evaluation of pain due to DPN. 6. Any anti-epileptic or anti-depressive treatment. Amityptiline (Elatrol/Elatrolet) or duloxetine (Cymbalta) are permitted at screening but not later. 7. Constant use of non-steroidal anti-inflammatory drugs or opiates that cannot be withdrawn during the washout period and the whole study duration. 8. Participation in another clinical trial in the last 3 months. 9. Poor compliance with prescribed medication or alcohol or drug abuse within 2 years before screening. 10. Hypersensitivity to paracetamol or any of the inactive ingredients in NRD135S. E1 capsules. 11. Any serious medical condition, including the presence of laboratory abnormalities, that places the patient at an unacceptable risk if he or she participates in this study or confounds the ability to interpret data from the study. 12. Patients with any hematological disorder. 13. Prisoners or subjects who are involuntarily incarcerated. 14. Subjects who are compulsorily detained for treatment of either a psychiatric or physical (e. g. infectious disease) illness. 15.
