Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
To obtain additional data at the 30 mg/kg dose level, a sixth cohort will be enrolled after the preliminary safety and tolerability of the 30 mg/kg dose in Cohort 4 is demonstrated. Cohort 6 will be comprised of 24 subjects (randomized 5 : 1 to CR6261 or placebo) following the same visit schedule as subjects in Cohorts 1-5.

8. Subjects must agree to not use OTC medications (including aspirin, decongestants, antihistamines and other NSAIDs), and herbal medication (including, but not limited to, herbal tea, St. John's Wort), within 14 days prior to study drug administration through the final follow-up visit, unless approved by the investigator and medical monitor. Occasional use of acetaminophen/paracetamol at recommended doses (≤ 1 gram/6 hours and ≤ 4 grams/day) and continued pre-existing use of vitamins or multivitamins at recommended doses is allowed.
9. Female subjects must:
* Be surgically sterile (have had a hysterectomy or bilateral oophorectomy, tubal ligation, or otherwise be incapable of pregnancy), or
* If heterosexually active, use two effective methods of birth control, including hormonal prescription oral contraceptives, contraceptive injections, contraceptive patch, contraceptive ring, intrauterine device, barrier method (e.g. condoms, diaphragm, or cervical cap), or spermicidal foam, cream, or gel), or
* Confirm male partner sterilization, or
* Not be heterosexually active Note: women who are not heterosexually active at screening must agree to utilize two effective methods of birth control if they become heterosexually active during their participation in the study.
Women must agree to continue using these methods of contraception throughout the study.
10. Females must have a negative urine pregnancy test at both screening and baseline.
11. If a man who is able to father a child and sexually active with a female of childbearing potential, he must agree to use a double barrier method of birth control (e.g. condom with spermicidal foam, cream, or gel) and to not donate sperm during the study.
12. Subjects must agree to avoid strenuous exercise (e.g. long distance running \>5 km/day, weight lifting, or any physical activity to which the subject is not accustomed) while confined to the Clinical Unit and for at least 72 hours prior to study drug administration and follow up visits.
Exclusion Criteria
2. Temperature \>99.5oF (37.5oC) at randomization.
3. Presence of a significant infection or known inflammatory process during screening or at the time of randomization.
