Phase 1 PK, Bioavailability, Safety Study of Clonidine MBT w Catapres in Healthy Volunteers
Phase 1 PK, Bioavailability, Safety Study of Clonidine MBT w Catapres in Healthy Volunteers
The purpose of this study is to determine the pharmacokinetic dose proportionality of 50 μg
 and 100 μg Clonidine and comparative bioavailability of clonidine with that from the
 Reference drug, Catapres® 100 μg oral tablets following single dose administration in healthy
 subjects.
A single blind, randomised, 3-period, 3-sequence single-dose crossover study to determine the
 pharmacokinetic dose proportionality of Clonidine MBT 50 μg and Clonidine MBT 100 μg and
 comparative bioavailability of clonidine from the Reference drug, Catapres® 100 μg oral
 tablets following single dose administration in healthy male and female subjects.

 36 subjects will be randomised for 30 to complete the study. The study will comprise of 3
 Treatment Periods (1, 2 and 3) and a post study follow up (7 - 12 days after the last dose).
 Study drug will be administered on the morning of Day 1. Pharmacokinetic (PK) blood samples
 will be collected for each of three treatment periods. Safety will be evaluated at specified
 times throughout the study. There will be at least 7 days between dose administrations.
Main Inclusion Criteria:

 -  Healthy males or females (non-pregnant/non-lactating) aged 18 - 50 years.

 -  A Body Mass Index (BMI) of 18-30.

 -  No clinically significant abnormal serum biochemistry, haematology and urine
 examination values.

 -  A negative urinary drugs of abuse screen.

 -  Negative HIV and Hepatitis B and C results.

 -  No clinically significant abnormalities in 12-lead electrocardiogram (ECG).

 -  No clinically significant abnormalities in blood pressure or pulse.

 -  No allergy or sensitivity to clonidine or any of its excipients.

 -  No allergy to milk or milk derivatives.

 -  Subjects must provide written informed consent to participate in the study

 Main Exclusion Criteria:

 -  Current or past medical condition that might significantly affect the pharmacokinetic
 or

 -  pharmacodynamic response to clonidine.

 -  Participation in a New Chemical Entity clinical study within the previous 3 months or
 a marketed drug clinical study within the previous 30 days.

 -  Pathological condition of the oral cavity that would affect administration via the
 buccal route.

 -  Raynaud's disease or other peripheral vascular disease.

 -  Receipt of regular medication within 14 days of the first dose that may have an impact
 on the safety and objectives of the study (at the Investigator's discretion).

 -  Evidence of renal, hepatic, central nervous system, respiratory, cardiovascular or
 metabolic dysfunction.

 -  Symptomatic postural hypotension evident on screening

 -  History or evidence of Suicidal Ideation and/or behaviour as determined by using
 Columbia-Suicide Severity Rating Scale (C-SSRS)
