(ii) Willing and able to continuously use one of the following methods of birth control during the course of the study, defined as those which result in a low failure rate (i.e., less than 1% per year) when used consistently and correctly: implants, injectable or patch hormonal contraception, oral contraceptives, IUD, double-barrier contraception, sexual abstinence. The form of birth control will be documented at screening and baseline.
You may not be if

2. Undiagnosed OSA with a STOPBANG score of 5 or higher
3. History of difficult airway in surgical setting
4. Any pulmonary/respiratory disorder that would merit categorization of patient as ASA Class 3 or higher
9. Clinically significant liver disease, determined by LFTs within the past 6 months
10. Clinically significant kidney disease determined by creatinine / GFR within the past 6 months
11. Symptomatic gastroesophageal reflux disease, hiatal hernia, taking medications causing delayed gastric emptying, or any other gastrointestinal disorder placing the patient at risk for aspiration or that would merit categorization of patient as ASA physical classification status of III or higher

14. Any other clinically significant abnormal laboratory result at the time of the screening exam that might affect safety, study participation or confound interpretation of study results
15. Any other clinically significant physical exam abnormality on the screening physical examination that might affect safety, study participation or confound interpretation of study results, including any condition that would merit categorization of patient as ASA Class 3 or higher
16. Participation in any clinical trial with an investigational drug or device that conflicts with this trial, within the past month or concurrent to study participation.
