8. Hypersensitivity or idiosyncratic reaction to components of ABP-700 (meglumine and/or sulfobutylether-beta-cyclodextrin), fentanyl, midazolam, egg, egg products, soybeans, soy, or to compounds related to the study medications.
9. History or presence of adrenal insufficiency as defined by serum cortisol level <6 Ķg/dL at screening.
10. Women who are pregnant or lactating.
11. Positive results for the urine drug screen and alcohol breath test at screening or check-in (Day -1).
12. Positive urine cotinine at screening.
13. Positive results at screening for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), or hepatitis C antibodies (HCV).
14. Single 12-lead ECG demonstrating QTcF interval >450 msec at screening.
15. Unable to refrain from or anticipates the use of any drug, including prescription and non-prescription medications, herbal remedies, or vitamin supplements beginning approximately 14 days prior to dosing and throughout the study, with the exception of oral contraceptives. Ibuprofen (1.2 g per 24 hour period) may be permitted during the study at the PIís discretion.
16. Use of any drugs known to be hormonal replacement therapy, inducers of cytochrome P450 (CYP) enzymes, including St. Johnís Wort, within 28 days prior to the first dose of study medication. Appropriate sources will be consulted by the PI to confirm lack of PK/PD interaction with study medication(s).
17. Have a diet incompatible with the clinic diet, in the opinion of the PI, within the 28 days prior to the first dose of study medication(s), and throughout the study.
18. Blood donation or significant blood loss within 90 days prior to dosing.
19. Plasma donation within 7 days prior to dosing.
20. Participation in another clinical trial within 90 days prior to dosing. The 90-day window will be derived from the date of the last study procedure (such as last blood collection or dosing) in the previous study to Day 1 of the current study.
21. Subjects who previously received ABP-700.

|- Brief summary||ABP-700 is an intravenous (IV) sedative-hypnotic agent currently in Phase I clinical development and is being developed the induction of general anesthesia and procedural sedation in patients undergoing diagnostic or therapeutic procedures.|
The highly dynamic nature of surgical and procedural intervention, as well as the short duration of these procedures, demands the development of potent yet rapidly reversible anesthetic agents. Ideally, the pharmacokinetics (PK) and pharmacodynamics (PD) of these anesthetic agents should be better matched to the procedures being performed. In general, currently used agents are either too long-acting or not easily titratable to the desired level of effect. The result is a clear unmet need for more effective drugs with a higher therapeutic index that exhibit a predictable PK/PD relationship and allow precisely tailored control of sedation and anesthesia. Newer sedative/anesthetic drugs that are potent, have minimal hemodynamic effects and reduced toxicities, and have a PK/PD profile that enables them to be more readily titratable are highly desired to meet these evolving patient and healthcare needs.
ABP-700 is a newly developed, potent, positive allosteric modulator of the GABAA receptor. Its mechanism of action is via potentiation of GABAA receptor activation producing its sedative and anesthetic effects. ABP-700 contains an ester bond that was precisely designed to undergo rapid hydrolysis in the body by nonspecific tissue esterases that produce an inactive carboxylic acid metabolite. This chemical approach has been used previously in approved drugs such as remifentanil, esmolol, and clevidipine, resulting in rapid inactivation of pharmacologic activity and a unique PK profile.
