Eligibility Criteria
Inclusion
- Inclusion criteria
- In order to be eligible to participate in this study, a subject must meet all of the following criteria:
- 18 years and older
- Subjects must be willing to give written informed consent for the trial and able to adhere to dose and visit schedule.
- Non-insulin-dependent diabetes mellitus (NIDDM) or healthy sex, age (± 3 yrs) and BMI (± 3 kg/m2) matched controls.
- Have no clinical or electrocardiographic signs of ischemic heart disease as determined by the Investigator with normal cardiac intervals appropriate for their gender. The Screening 12 lead ECG conduction intervals must be within gender specific normal range (e.g., QTcF ≤ 430 msec, PR interval ≤ 220 msec). ECGs are to be judged by the investigator or sub investigator as per standardized procedures.
- Vital sign measurements must be within the following ranges: (Individuals with values outside (or indicate lower or higher) of these ranges may be enrolled if clinically acceptable to the investigator and sponsor.
- body temperature, between 35.5°C and 37.5°C
- systolic blood pressure, 90 to 150 mmHg
- diastolic blood pressure, 40 to 95 mmHg
- pulse rate, 40 to 100 bpm
- Subjects must be free of any clinically significant disease that would interfere with the study evaluations.
- Subjects presenting out of range values of lab/ECG/vital signs compatible with normal variation of the normal healthy subject can be included in the study at the investigator's discretion and sponsor written approval.
- Positive Allen's test
- Fitzpatrick skin type I or II
- A potential subject who meets any of the following criteria will be excluded from participation in this study:
- Insulin dependent diabetes mellitus
- Diagnosed Obstructive Sleep Apnea (OSAS) or high suspicion of OSAS determined by a STOP-BANG score \> 5
- Respiratory or cardiovascular disease
- Smoking/vaping
- Positive pregnancy test
- conditions that result in elevated levels of methaemoglobinia
- body mass index \> 35 kg/m2
- Use of illicit drugs
- Use of prescription opioids or benzodiazepines
- Failure of the drug of abuse tests at screening or check-in.
- History of dyspnea, asthma, tuberculosis, chronic obstructive pulmonary disease, or any other ventilatory / lung disease.

- Subjects who, in the opinion of the investigator, will not be able to participate optimally in the study.
- Subject who has a history of any infectious disease within 4 weeks prior to drug administration that in the opinion of the investigator, affects the subject's ability to participate in the trial.
- Subjects who are part of the study staff personnel or family members of the study staff personnel.
- Subjects who have demonstrated allergic reactions (e.g., food, drug, atopic reactions or asthmatic episodes) which, in the opinion of the investigator and sponsor, interfere with their ability to participate in the trial.
- Personal or family history of arrhythmias or ECG conductance abnormalities.
- Hypokalemia defined as \<3.5 mmol/L
