|Condition or disease||Intervention/treatment||Phase|
|Healthy||Drug: Oritavancin Drug: Placebo (D5W)||Phase 1|
Oritavancin has been approved in the United States for the treatment of adult patients with acute bacterial skin and skin structure infections (ABSSSIs) caused or suspected to be caused by susceptible isolates of designated Gram-positive microorganisms. The purpose of this study is to determine the (a) safety and tolerability and (b) pharmacokinetic profile of multiple doses of Oritavancin given over a 7-8 week period.
Cohort 1 will consist of 14 subjects, randomized to receive a total of four doses of either oritavancin or placebo, given once every two weeks in a double-blind fashion.
After completion of cohort 1, a Data Safety Monitoring Board will review the blinded safety data and pharmacokinetics (PK) for cohort 1 and determine whether to continue with cohort 2, modify cohort 2 or end the study. The cohorts for this study are sequential.
Cohort 2 will consist of 14 subjects, randomized to receive a total of eight doses of either oritavancin or placebo (4 subjects) given once every week in a double-blind fashion.

|Ages Eligible for Study:||18 Years to 55 Years (Adult)|
|Sexes Eligible for Study:||All|
|Accepts Healthy Volunteers:||Yes|
- Subject is able to provide written informed consent before initiation of any study-related procedures.
- Healthy male or female between the ages of 18 and 55 years, inclusive.
- Body mass index (BMI) < 45 kg/m2.
- Subject is in good health based on medical history and physical examination findings and has no clinically meaningful safety laboratory abnormalities (CBC, blood chemistry, and urinalysis) or 12 lead ECG results, as assessed by the PI.
- Vital signs (BP, pulse and temperature) measured at screening/baseline must be within the following ranges: SBP ≥90 to ≤150 mm Hg, DBP ≥45 to ≤90 mm Hg; Heart Rate ≥ 40 to ≤90 bpm (taken after resting in a supine position for at least 5 minutes).
- Willing to avoid all medications (other than the study drug and acetaminophen/paracetamol for minor aches/pains) during the study. This includes prescription and non-prescription medications, vitamins, herbal supplements, and nutriceuticals.
- Subject is a non-smoker and is willing to abstain from alcohol/illegal drug use for the duration of the study.
- If the female subject is surgically sterile, postmenopausal, or, if of childbearing potential, agrees to use at least 2 highly-effective methods of birth control (e.g. prescription oral contraceptives, contraceptive injections, contraceptive patch, intrauterine device, barrier methods, abstinence) or male partner sterilization alone for the duration of the study until 60 days after study drug administration.
- Has any condition, including findings in the medical history or in pre-study assessments that constitutes a risk or a contraindication for the participation in the study or completing the study.
- Female subjects of childbearing potential that have a positive test result for human chorionic gonadotropin (hCG) at screening.
- Female subjects who are nursing.
- Positive urine test for alcohol and/or for drugs of abuse at screening.
- Has a history or presence of alcohol/drug abuse within 2 years. Alcohol abuse is defined as regularly consuming >3 units/day (21 units per week for men), >2 units/day (14 units/week) for women. 1 unit of alcohol is defined as a can of 4% beer (330 mL), approximately 190 mL of 6-7% beer (malt liquor), a glass of 40% spirits (30 mL), or a glass of wine (100 mL).

- Treatment with any prescription or OTC drugs, within 2 weeks or 5 half-lives, whichever is longer, or herbal nutritional supplements within 2 weeks of screening, with the exception of acetaminophen/paracetamol for minor aches/pains. Subjects will not be allowed to receive medications for the duration of the study (except the above mentioned acetaminophen/paracetamol). Birth control or other hormone replacement is also permitted as long as it has been taken at a stable dose for at least three months before the screening visit and remains stable for the duration of the study.
