1. Subject is able to provide written informed consent before initiation of any study-related procedures.
2. Healthy male or female between the ages of 18 and 55 years, inclusive.
3. Body mass index (BMI) < 45 kg/m^2.
4. 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.
5. 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).
6. 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 nutraceuticals.
7. Subject is a non-smoker and is willing to abstain from alcohol/illegal drug use for the duration of the study.
8. 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.

Exclusion Criteria:

1. 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.
2. Female subjects of childbearing potential that have a positive test result for human chorionic gonadotropin (hCG) at screening.
3. Female subjects who are nursing.
4. Positive urine test for alcohol and/or for drugs of abuse at screening.
5. 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).
6. History of hypersensitivity to drugs with a similar chemical structure (i.e. glycopeptide antibiotics) to oritavancin or any of its excipients.
7. Blood or plasma donation within the past 2 months.
8. Subjects who participated in other clinical research studies involving the evaluation of other investigational drugs or devices within 30 days or 5 half-lives, whichever is longer, prior to screening and/or unwilling to allow at least two months before participation in another drug trial following the current trial.
9. 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.
10. Males who are unwilling to practice abstinence or use an acceptable method of birth control during the entire study period (i.e. condom with spermicide).
11. Subjects that have any surgical or medical condition that could interfere with the administration of the study drug.
12. Subjects that have known active hepatitis B or C, or human immunodeficiency virus (HIV) infection or has known immune deficiency disease at screening.
13. Subjects that have any condition that would confound or interfere with the assessment of safety.
14. Subjects that have poor IV access as determined by the investigator. Subjects excluded for any of the previous criteria may only be rescreened for participation after discussion with sponsor and principal investigator.
15. Prior exposure to Oritavancin alone or in combination with another product.
