Brief Summary
This is a Phase 1b study involving multiple oral doses of AV-101 in healthy male and female subjects. The safety, pharmacokinetics, and antihyperalgesic effect of AV-101 on capsaicin-induced hyperalge...
Detailed Description
Healthy subjects will be randomized into three dose cohorts (360, 1,080, and 1,440 mg) to receive daily oral doses of AV-101 for 14 consecutive days. Each cohort has 12 subjects on active drug and 4 s...
Eligibility Criteria
Inclusion
- A subject will be eligible for participation in the full study only if all of the following criteria are met:
- Be male or female, aged 21 to 60 years inclusive, healthy, able and willing to provide written informed consent to participate in the study.
- Be able to read and speak English sufficiently to understand and follow the study instructions, including completion of pain intensity rating scales.
- For males, must use birth control (condom) to prevent fathering children; for females must be nonlactating, not pregnant, and using a reliable contraception method (e.g., abstinence, intrauterine device, hormonal birth control, or double barrier method \[male condom, female condom, or diaphragm plus a spermicidal agent such as contraceptive foam, jelly, or cream\]).
- Have a visual analog pain score of at least 4 out of 10 at screening.
Exclusion
- Subjects will be excluded from the study if any one or more of the following conditions apply:
- History of peripheral neuropathy or any chronic pain condition.
- History of significant hepatic, ophthalmic (including previous or current cataract), cardiovascular, renal, gastrointestinal, hematological, neurological, endocrine (including diabetes), metabolic, pulmonary, or psychiatric disease. Significance will be determined by the principal investigator.
- Clinically significant abnormality on the screening electrocardiogram that in the judgment of the investigator would place the subject at risk of cardiac adverse event as a result of capsaicin injection or administration of AV-101.
- Cognitive or psychiatric disorders that may diminish compliance with study procedures.
- Dermatopathology, skin hypersensitivity, or skin lesions in the areas of capsaicin application.
- Allergy to capsaicin or the study medication.
- Current tobacco use.
- Use of chemotherapy agents or history of cancer, other than resolved skin cancer, within 5 years before the screening visit.
- History of drug or alcohol abuse within 1 year before screening.
- History of AIDS, testing as HIV positive, or use of antiretroviral therapy.
- Use of, within 4 weeks before study drug dosing, any investigational drug, any epidural or intrathecal agent, corticosteroids, topical anesthetics, topical analgesics, central alpha agents (e.g., clonidine), alpha blockers (e.g., praxosin, terazosin), beta blockers, calcium channel blockers, or ACE inhibitors.
- Use within 7 days before and during the entire period of study drug dosing of long-acting nonsteroidal anti-inflammatory drug (NSAIDs) such as piroxicam or naproxen.
- Use within 36 hours before and during the entire period of study drug dosing of NSAIDs, aspirin, acetaminophen, antihistamines, sympathomimetics (e.g., pseudoephedrine and ephedrine), caffeine or alcohol.
