- 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,
- OR
- 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.)
Who cannot join
- 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.
Show all 12Show fewer
- 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.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Capsaicin Dermal Patch in people with HIV Infections, run by NeurogesX at 3 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 17 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 14 Sep 2007. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Sep 2007.
