study drug administration.
9. Subjects with normal lung function defined as =80% predicted forced expiratory volume
in one second (FEV1) at screening.

Exclusion criteria:
1) Any clinically significant abnormality at physical examination, clinically significant
abnormal laboratory test results or positive test for HIV, hepatitis B, or hepatitis C
found during medical screening.

blood pressure less than 40 or greater than 90 mmHg, or heart rate less than 40 or
greater than100 bpm, oxygen saturation less than 95% O2) at screening.
5. History of alcohol abuse within 1 year prior to screening or regular use of alcohol
within 6 months prior to the screening visit. Regular use of alcohol is defined as
greater than 14 units of alcohol per week, where 1 unit is defined as 375 mL of beer

6. History of drug abuse within 1 year prior to screening, recreational use of soft drugs
(such as tetrahydrocannabinol [THC]) within 1 month prior to the screening visit, or
hard drugs (amphetamines, methamphetamines, methadone, barbiturates, benzodiazepines,
cocaine, opiates, methyledioxymethamphetamine [MDMA], and phencyclidine [PCP]) within
3 months prior to screening.
7. Participation in a clinical research study involving the administration of an
investigational or marketed drug or device within 30 days prior to the first dosing,
administration of a biological product in the context of a clinical research study
within 90 days prior to the first dosing, or concomitant participation in an
investigational study involving no drug or device administration.
8. Use of medications for the timeframes specified below, with the exception of
medications exempted by the Investigator on a case-by-case basis because they are
judged unlikely to affect the PK profile of the study drug or subject safety (e.g.,
topical drug products without significant systemic absorption):
1. Prescription medications (except for hormonal contraceptives) within 14 days
prior to the first dosing;
2. Over-the-counter products and natural health products (including herbal remedies,
such as St. John's wort, homeopathic and traditional medicines, probiotics, food

the exception of the occasional use of acetaminophen/paracetamol (up to 2 g/day),
ibuprofen (up to 800 mg/day), and topical formulations without significant
systemic absorption;
3. Depot injection or implant (except for hormonal contraceptives) of any drug

499 mL within 56 days prior to the first dosing.
10. Breast-feeding subject.

a symptomatic viral or bacterial infection, within 2 weeks prior to the first dosing.
15. Any reason that, in the opinion of the Investigator, would prevent the subject from
participating in the study.
