This protocol describes a double-blind study to evaluate the safety and pharmacokinetics of
multiple IV doses of 1200 mg ORBACTIV (oritavancin) in healthy subjects.
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.
1. Subject is able to provide written informed consent before initiation of any
2. Healthy male or female between the ages of 18 and 55 years, inclusive.
3. Body mass index (BMI) < 45 kg/m2.
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
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.
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
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.
