Safety, Tolerability and Preliminary Efficacy of AZD5213 in Combination With Pregabalin in Subjects With PDN and Good Pain Reporting Ability

Completed · Phase 2 · Has a placebo group

Conditions studied: Diabetic Neuropathy, Painful; Diabetic Neuropathies

In brief

This is a 2-part study. In Part 1 of the study, subjects will undergo a pain reporting training program in which a painful stimulus will be applied to the subject's hand, and the subjects will be asked to report how painful the stimulus is. Over the course of the pain training sessions, feedback will be provided to the subject about how accurately they are reporting their degree of pain, relative to the amount of pressure stimulus applied to evoke pain. Those subjects who have adequate pain reporting ability will be asked to continue into Part 2 of the study in which 3 different blinded study drugs will be administered to each subject, in a crossover design to compare whether or not the study drugs improve pain associated with diabetic neuropathy.

Able to participate in all scheduled evaluations and to complete all required tests and procedures. 9. In the opinion of the investigator, the subject must be considered likely to comply with the study protocol and to have a high probability of completing the study.

You may not qualify if…

• Known or suspected hypersensitivity to pregabalin. 2. Clinically important illness or infection (e.g., chronic, persistent, or acute infection) within 30 days prior to screen or between screen adn baseline. 3. Presence of any psychiatric or neurologic disorder or any other disorder or symptom, if, in the judgement of the investigator, the disorder or symptom is likely to confound interpretation of drug effect or affect the subject's ability to complete the study. Any clinically important abnormality, as determined by investigator at Screen or baseline, in physical or neurologic examination, vital sign, ECG, or clinical laboratory test results that could be detrimental to the subject, or could affect the subject's ability to complete the study. 4. Initiation or change in intensity or frequency of non-pharmacologic therapy for PDN, including psychotherapy, physical therapy, massage, acupuncture, acupressure, or chiropractic care, within 3 months prior to baseline).
