The purpose of the study is to gain initial information on the tolerability and feasibility of high-concentration capsaicin patches for the treatment of painful HIV-associated neuropathy, whether resulting from HIV disease and/or antiretroviral drug exposure. The study will also provide preliminary safety and efficacy information.
Drug: Capsaicin Dermal Patch
||Masking: Open Label
Primary Purpose: Treatment
||An Open-Label Pilot Study of High-Concentration Capsaicin Patches in the Treatment of Painful HIV-Associated Neuropathy
|Ages Eligible for Study:
||18 Years to 75 Years
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- Between 18 and 75 years of age.
- Documented evidence of HIV-1 infection.
- Painful HIV-associated neuropathy, whether resulting from HIV disease and/or antiretroviral drug exposure, with primary symptoms of pain, burning or dysesthetic discomfort in both feet for at least 2 months prior to Screening Visit.
- Diminished ankle reflexes (compared to the knee) or absent ankle reflexes,
- Distal diminution of either vibration sensation or pain or temperature sensation in the legs.
- Either no neurotoxic antiretroviral (i.e., didanosine [ddI], zalcitabine [ddC], or stavudine [d4T]) exposure for at least 8 weeks prior to Screening Visit,
- Currently on stable dose(s) of any of the neurotoxic antiretrovirals listed above for at least 8 weeks prior to Screening Visit, without a foreseeable need to change doses or medications for duration of study.
- Screening Pain Sum Score of 12 to 36.
- Intact, unbroken skin over the painful area(s) to be treated.
- If taking chronic pain medications, be on a stable (not PRN) regimen for at least 7 days prior to Treatment Visit (Day 0) and willing to maintain medications at same stable dose(s) and schedule throughout the study.
- Be willing and able to use Roxicodone® (oxycodone) oral solution, if needed, to relieve treatment-associated discomfort.
- Female subjects with child-bearing potential must have a negative urine or serum pregnancy test, to be performed at the Screening Visit.
- All subjects must be willing to use effective methods of birth control and/or refrain from participating in a conception process during the study and for 30 days following experimental drug exposure.
- Be willing and able to comply with protocol requirements for the duration of study participation. (Such requirements include, but are not limited to: completing a daily pain diary, attending all study visits, and refraining from extensive travel during study participation.)
- Presence of acute, active opportunistic infection, except oral thrush; oral, genital, or rectal herpes; and Mycobacterium avium bacteremia within 2 weeks prior to Screening Visit.
- Significant pain of an etiology other than painful HIV-associated neuropathy, for example, compression-related neuropathies, e.g., spinal stenosis, or fibromyalgia or arthritis. Subjects must not have significant ongoing pain from other cause(s) that may interfere with judging HIV-associated neuropathy pain.
- Evidence of another contributing cause for peripheral neuropathy, e.g., diabetes mellitus, hereditary neuropathy, vitamin B12 deficiency (B12 level less than or equal to 200 pg/mL) or less than 3 months of B12 supplementation prior to Screening Visit, or treatment within 90 days prior to Screening Visit with any drug that may have contributed to the sensory neuropathy.
- Any implanted medical device (spinal cord stimulator, intrathecal pump or peripheral nerve stimulator) for the treatment of neuropathic pain.
- Recent use (within 21 days preceding the Treatment Visit [Day 0]) of any topically applied pain medication, such as non-steroidal anti-inflammatory drugs, menthol, methyl salicylate, local anesthetics (including Lidoderm®), steroids or capsaicin products on the painful areas.
- Treatment for acute opportunistic infections within 14 days before Treatment Visit (Day 0). Maintenance treatment of cytomegalovirus (CMV) retinitis, Mycobacterium avium bacteremia, or cryptococcal meningitis is permitted.
- Current use of any investigational drug, or Class 1 anti-arrhythmic drugs (such as tocainide and mexiletine).
- Hypersensitivity to capsaicin (i.e., chili peppers or OTC capsaicin products), local anesthetics, Roxicodone 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.
- Currently have active malignant disease. Malignancies in remission that do not require further treatment or Kaposi's sarcoma requiring local treatment only are allowed.
- High tolerance to opioids that precludes the ability to relieve treatment-associated discomfort with Roxicodone® if needed, as judged by investigator.
- History or current problem with prescription drug, illicit substance, or alcohol abuse from self report or as judged by investigator.
