4. Willing and able to communicate with the investigator.

5. Vital signs at screening (after five minutes resting measured in the supine position) within the following ranges:

   1. Body temperature between 35.0-37.5°C
   2. Systolic blood pressure, 90-150 mmHg*
   3. Diastolic blood pressure, 60-90 mmHg*
   4. Pulse rate, 40-99 beats per minute (bpm)*. *Blood pressure and pulse rate will be taken again in a standing position. After two minutes standing, there shall be no more than a 20 mmHg drop in systolic or 10 mmHg drop in diastolic blood pressure, associated with clinical manifestation of postural hypotension.
6. Have a body weight of at least 50.0 kg and have a body mass index (BMI) between 19.0 and 35.0 kg/m2, inclusive.
7. Willing for his or her name to be notified to the responsible authorities for participation in this study, as applicable in individual countries.

8. Willing to allow his or her primary care practitioner and consultant to be notified of participation in the study.

   Inclusion Criteria for Renally Impaired Subjects:

9. Severe renal impairment or ESRD [clinically significantly abnormal creatinine and creatinine clearance (CLcr <30 mL/min and not requiring dialysis].

10. Onset of renal impairment must be documented at least 3 months prior to study start.

    Inclusion Criteria for Normal Renal Function Subjects:

11. In good health as determined by medical history, physical examination, biochemistry, hematology, urinalysis, hepatitis B and C, and HIV testing.
12. Creatinine clearance (CLcr) > 80 mL/min indicating normal renal function.
13. Individually matched to a renally impaired subject with respect to age (within the decile or 5 years, whichever is less), gender, and BMI (+/- 10% BMI).

Exclusion Criteria:

Subjects meeting any of the following criteria will not be eligible for this trial:

1. Donation or loss of 400 mL or more of blood within eight weeks prior to dosing and unwilling to abstain from donation of blood during the study.
2. Significant concomitant illness within the two weeks prior to dosing.
3. At high risk for requiring hospital admission or extended hospital stay during study period or any scheduled elective hospitalization during the planned study duration.
4. Requiring dialysis or expected to require dialysis during study period.
5. Has any surgical or medical condition, significant disease or disorder or any finding on physical examination and/or oral examination (other than their underlying condition) which might significantly alter the absorption, distribution, metabolism or excretion of drugs or that, in the opinion of the investigator, may put the subject at risk, influence the result of the study, or the subject's ability to participate in the study.
6. History of renal transplant.
7. Clinical evidence of acute or chronic liver disease or liver injury as indicated by clinically significant abnormal liver function tests such as Aspartate Aminotransferase, Alanine Aminotransferase, gamma glutamyl-transpeptidase, alkaline phosphatase (any ≥2.5 x Upper Limit of Normal [ULN] ) or serum bilirubin (≥1.5 x ULN) unless there is another likely explanation (e.g. Gilbert's syndrome).
8. Any change in medication within 14 days prior to dosing or planned for anytime throughout the study which might significantly alter the absorption, distribution, metabolism or excretion of the Investigational Medicinal Product (IMP), in the opinion of the investigator.
9. Any known or suspected hypersensitivity to cannabinoids or any of the excipients of the IMP(s).
10. Positive result for the presence of HBsAg, HCAb, or HIV antibodies.
11. Currently using or has used cannabis and/or cannabinoid-based medications (e.g. Marinol®, Nabilone®, Cannador®) within 30 days of study entry and unwilling to abstain for the duration of the study.
12. Any known or suspected history of a substance abuse/dependence disorder within the 12 months prior to dosing or current use of an illicit drug or current non prescribed use of any prescription drug, or evidence of such abuse as indicated by the laboratory assays conducted during the screening or baseline evaluations.
13. Current heavy alcohol consumption (more than 60 g of pure alcohol per day for men, and more than 40 g of pure alcohol per day for women).
14. Unwilling to abstain from drinking alcohol for 24 hours prior to each visit and during the inpatient period of the study.
15. Unwilling to abstain from nicotine products from midnight Day -2 to 48 hours post dose.
16. Unwilling to abstain from grapefruit products for one week prior to and throughout the inpatient period.
17. Consume more than five caffeinated beverages per day (e.g. five cups of tea or coffee or cans of cola) or who are unwilling to abstain from consumption of caffeine-containing food and beverages throughout the inpatient period.
18. Any known or suspected history or immediate family history of schizophrenia, or other psychotic illness, history of severe personality disorder or other severe significant psychiatric disorder other than depression associated with underlying condition.
19. Any history of epilepsy as evidenced by one or more seizures in the last 12 months.
20. Significant cardiac disease, or has a cardiac disorder that in the opinion of the investigator would put the subject at risk of a clinically relevant arrhythmia or myocardial infarction, or has a secondary or tertiary atrioventricular block, or evidence of clinically significant cardiac disease on ECG at screening.

21. Sexually active males whose partner is of childbearing potential who do not agree to practice two different methods of birth control or remain truly abstinent during the study and for three months after the last dose of study medication. Sexually active females of childbearing potential who do not agree to practice two different methods of birth control or remain truly abstinent during the study and for three months after the last dose of study medication. If employing birth control, two of the following precautions must be used: vasectomy, tubal ligation, vaginal diaphragm, intrauterine device, birth control pill, birth control implant, birth control depot injection, condom, or sponge with spermicide. However, a male condom must not be used in conjunction with a female condom as this may not prove effective.

    Note: Non-childbearing potential is defined as female subjects who are surgically sterile (i.e., have undergone bilateral salpingo-oophorectomy, hysterectomy) and female subjects who have been postmenopausal for at least 12 consecutive months.

22. Pregnant, lactating or planning pregnancy during the course of the study and for three months thereafter.
23. Received an IMP within 30 days or five times the half-life of the IMP (whichever is greater) prior to the screening visit.
24. Travel outside the country of residence planned during the study.
25. Previously enrolled into this study or any other Sativex® study.
