Safety and Effectiveness of Repeated Administration of QUTENZA Patches for Treatment of Pain Caused by Nerve Damage (STRIDE)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
In this study all patients will be treated with the same medicine, the QUTENZA patch. Subjects will receive up to 6 QUTENZA patch applications over 12 months.
Condition or disease
The rationale for the current study is to evaluate the safety of repeated QUTENZA applications, including the effect of QUTENZA on sensory function in subjects diagnosed with different types of Peripheral Neuropathic Pain (PNP). In order to adequately assess the long-term safety QUTENZA in well defined patient populations the current study will enroll a minimum of 100 patients each with HIV-Associated Neuropathy (HIV-AN) and Postherpetic Neuralgia (PHN).

Layout table for eligibility information
Ages Eligible for Study:
18 Years to 90 Years (Adult, Older Adult)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Common Inclusion Criteria:
Be in good health as determined by the investigator
Average pain score >=4 during screening period (using the average reported pain from the Brief Pain Inventory [BPI])
Intact, non-irritated, dry skin over the painful area(s) to be treated
All females of child bearing potential must be willing to use effective methods of birth control during the study and for 30 days following study termination
Be willing and able to comply with protocol requirements for the duration of study participation
Population-specific Inclusion Criteria:
All subjects must meet one (and only one) of the Population-Specific Inclusion Criteria for PHN, HIV-AN, PNI or ISNN or have adequately characterized PNP based on clinical history and examination.
Postherpetic Neuralgia (PHN): Prior diagnosis of PHN with pain persisting at least 3 months since shingles vesicle crusting, documented by the primary treating physician or investigator
Painful HIV-Associated Neuropathy (HIV-AN): Presence of HIV-AN existing for a minimum of 3 months, confirmed using the Brief Peripheral Neuropathy Screen (BPNS) at the time of study entry
Peripheral Neuropathic Injury (PNI): Diagnosis of Post-traumatic Peripheral Neuropathic Pain syndrome, including post-surgical neuropathic pain, neuropathic pain due to peripheral nerve injury, confirmed by a qualified pain specialist and persisting for a minimum of 3 months following the traumatic event
Idiopathic Small Nerve Neuropathy (ISNN): Diagnosis of ISNN based on clinical criteria (e.g. quantitative sensory testing) or skin biopsy
Neuropathy exclusively or predominantly affecting A-δ (small myelinated) and nociceptive C (unmyelinated) nerve fibres
Loss of pinprick and temperature sensation in feet
Other Peripheral Neuropathic Pain (PNP): Adequately characterized PNP based on clinical history and examination existing at the time of screening
Any prior receipt of QUTENZA open label or blinded study patches
Use of oral or transdermal opioids exceeding a total daily dose of morphine of 80 mg/day, or equivalent; or any parenteral opioids, regardless of dose, within 7 days preceding the first patch application visit
Lack of an effective pain medication strategy for the subject, such as unwillingness to use opioid analgesics during study treatment, or high tolerance to opioids precluding the ability to relieve treatment-associated discomfort with oxycodone or other analgesic, as judged by the investigator
Active substance abuse or history of chronic substance abuse within 1 year prior to enrolment or prior chronic substance abuse (including alcoholism) likely to re-occur during the study period as judged by the investigator
Use of any topical pain medication, such as non-steroidal anti-inflammatory drugs, menthol, methyl salicylate, local anesthetics, steroids or capsaicin products on the painful areas within 7 days preceding the first patch application visit
Current use of any investigational agent (excluding antiretrovirals in Phase 3 evaluation to treat HIV infection)
Unstable or poorly controlled hypertension or a recent history of a cardiovascular event which, in the opinion of the investigator, would put the patient at risk of adverse cardiovascular reactions related to the patch application procedure
Evidence of another contributing cause for peripheral neuropathy, and/or treatment within 90 days prior to screening visit with any drug that may have contributed to the sensory neuropathy
Past or current history of Type I or Type II diabetes mellitus
Current psychotic disorders
Clinically significant abnormal ECG at screening
Hypersensitivity to capsaicin (i.e., chilli peppers or Over-the-counter [OTC] capsaicin products), any QUTENZA excipients, local anesthetics, oxycodone, hydrocodone, or adhesives
Significant ongoing or untreated abnormalities in cardiac, renal, hepatic, or pulmonary function that may interfere either with the ability to complete the study or the evaluation of adverse events
Significant pain of an aetiology other than painful HIV-AN, PHN, PNI, ISNN or other adequately characterized PNP for example, compression-related neuropathies (e.g., spinal stenosis), fibromyalgia or arthritis
Posttraumatic neuropathic pain due to Complex Regional Pain Syndrome (CRPS, Type I)
Active malignancy or history of malignancy during the past 5 years (a history of squamous cell carcinoma or a basal cell carcinoma not involving the area to be treated is allowed)
Evidence of cognitive impairment including dementia that may interfere with subject's ability to complete study evaluations and recall pain levels in the past 24 hours
Planned elective surgery during the trial
Neuropathic pain areas located only on the face, above the hairline of the scalp, and/or in proximity to mucous membranes
Female subjects of child-bearing potential with a positive serum or urine pregnancy test prior to treatment
