入选标准
- •Age ≥ 18 years to 75 years;
- •Documented history of Type I or II diabetes with current treatment control(glycosylated hemoglobin A1c of ≤ 10.0% at Screening) and currently on oral medication and / or insulin;
- •Taking 60 to 200 mg morphine milligram equivalents (MME)/day for painful DPN at study entry and must be on stable regimen starting at Day -21; percent of overall requirement as immediate release must be ≥ 30%;
- •No significant changes anticipated in diabetes medication regimen;
- •No new symptoms associated with diabetes within the last 3 months prior to study entry;
- •Diagnosis of painful diabetic peripheral neuropathy in both lower extremities;
- •Global pain intensity [Numerical rating scale, average NRS] score over the week prior to initial Screening visit must be ≥ 4 and ≤ 9 (0 = no pain - 10 = worst pain imaginable);
- •Symptoms from the Brief Pain Neuropathy Screening (BPNS) is ≤ 5 point difference between legs at Initial Screening;
- •The physical examination component of the Michigan Neuropathy Screening Instrument Score (MNSI) is ≥ 3 at Initial Screening;
- •Subjects on gabapentin (Neurontin), pregabalin (Lyrica), or duloxetine (Cymbalta) for painful DPN at study entry must be on a stable regimen of these treatments for at least 7 days prior to start of oral placebo run-in; and
- •If female of childbearing potential, negative urine pregnancy test at screening and using acceptable method of birth control during the study.
排除标准
- •Small fiber polyneuropathy caused by condition other than diabetes;
- •Additional pain syndrome of overall greater intensity than that of DPN that, in the opinion of the investigator, would prevent assessment of DPN;
- •Progressive or degenerative neurological disorder;
- •Inflammatory disorder of the blood vessels (inflammatory angiopathy, such as Buerger's disease);
- •Active infection, in the opinion of the investigator;
- •Chronic inflammatory disease (e.g., Crohn's disease, rheumatoid arthritis), in the opinion of the investigator;
- •Positive HIV or HTLV at Screening;
- •Active Hepatitis B or C as determined by Hepatitis B core antibody (HBcAb; IgG and IgM), antibody to Hepatitis B surface antigen (HBsAb), Hepatitis B surface antigen (HBsAg) and Hepatitis C antibodies (Anti-HCV) at Screening;
- •Subjects with known immunosuppression or currently receiving immunosuppressive drugs, chemotherapy or radiation therapy;
- •Stroke or myocardial infarction within last 3 months;
- •Specific laboratory values at Screening including: Hemoglobin < 8.0 g/dL, WBC < 3,000 cells per microliter, platelet count <75,000/mm3, Creatinine > 2.0 mg/dL; AST and/or ALT > 3 times the upper limit of normal or any other clinically significant lab abnormality which in the opinion of the investigator should be exclusionary;
- •Proliferative retinopathy within 5 years of signing consent or any ophthalmological condition which, in the opinion of the investigator, should be exclusionary; any condition that precludes standard ophthalmologic examination;
- •Uncontrolled hypertension defined as sustained systolic blood pressure (SBP) > 200 mmHg or diastolic BP (DBP) > 110 mmHg at Screening;
- •Subjects with a recent history (< 5 years) of or new screening finding of malignant neoplasm except basal cell carcinoma or squamous cell carcinoma of the skin (if excised and no evidence of recurrence for one year); subjects with family history of colon cancer in any first degree relative are excluded unless they have undergone a colonoscopy in the last 12 months with negative findings;
- •Use of the following drugs / therapeutics is PROHIBITED past Day -14:
- •skeletal muscle relaxants, benzodiazepines (except for stable bedtime dose),
- •capsaicin, local anesthetic creams and patches, isosorbide dinitrate (ISDN) spray,
- •transcutaneous electrical nerve stimulation (TENS), acupuncture
- •If not using gabapentin (Neurontin), pregabalin (Lyrica), duloxetine (Cymbalta), any antidepressants (e.g., amitriptyline and venlafaxine), any other antiepileptics (e.g., valproic acid, carbamazepine, or vigabatrin), subjects must agree not to start these drugs until after Day
- •Subjects on these medications on day of informed consent must maintain a stable dose starting at Day -21 until Day 180; any changes in analgesic regimen after Day 180 are at the discretion of the investigator;
- •Use of certain COX-1/COX-2 inhibitor drug(s), steroids (except inhaled, ocular, or intra-articular steroids), and anti-Vascular Endothelial Growth Factor (VEGF) agents; subjects may be enrolled if willing/able to undergo medication wash-out prior to the first dosing and to refrain from taking these drugs for the duration of the study;
- •Major psychiatric disorder within last 6 months that would interfere with study participation;
- •Body mass index (BMI) > 45 kg/m2 at Screening;
- •Any prior or lower extremity amputation due to diabetic complications;
- •History of illicit drug or alcohol abuse / dependence in the past 2 years, including but not limited to, cocaine, amphetamines, non-prescribed opioids, and non-prescribed benzodiazepines);
- •Use of an investigational drug or treatment in past 6 months; and
- •Unable or unwilling to give informed consent.
