Clinical Trial Summary

The purpose on this study was to determine whether the test product, Haloperidol Tablets, 2 mg (Cycle Pharmaceuticals Ltd), and the reference product, Haloperidol Tablets, United States Pharmacopeia (USP), 2 mg (Mylan Pharmaceuticals Inc.) are bioequivalent under fed conditions.

Description:

The specific aim was to conduct a single dose, open-label, randomized, two period crossover pivotal study to determine the bioequivalence of two formulations containing haloperidol 2 mg in healthy males and females under fed conditions.

A total of 32 healthy female and male volunteers (age 18 to 55 years old) were entered into the study. Volunteers were determined to be free of significant medical conditions as assessed by medical history, physical examination, and blood and urine tests. Volunteers were randomly allocated to a treatment sequence, before administration of investigational medicinal product (IMP) under fed conditions.

A wash-out period of at least 14 calendar days (minimum number of days based on half-life of the analyte) between consecutive administrations of the IMP was maintained.

Blood samples were collected at at pre-dose (0 hours), at 30 minutes, at 1 hour,

1 hour 30 minutes, 2 hours, 2 hours 30 minutes, 3 hours, 3 hours 30 minutes, 4 hours, 4 hours 30 minutes, 5 hours, 5 hours 30 minutes, 6 hours, 8 hours, 12 hours, 16 hours, 24 hours, 30 hours, 36 hours, 48 hours, 72 hours, 96 hours, 120 hours, 144 hours, 168 hours and 192 hours post-dose (total: 26 samples per treatment period).

• Use of any medication, prescribed or over-the-counter or herbal remedies, within 2 weeks before the first administration of IMP except if this will not affect the outcome of the study in the opinion of the investigator. In this study the concomitant use of hormonal contraceptives is NOT allowed.

• Participation in another study with an experimental drug, where the last administration of the previous IMP was within 8 weeks (or within 5 elimination half-lives for chemical entities or 2 elimination half-lives for antibodies or insulin, whichever is the longer) before administration of IMP in this study, at the discretion of the investigator.

• Treatment within the previous 3 months before the first administration of IMP with any drug with a well-defined potential for adversely affecting a major organ or system.

• A major illness during the 3 months before commencement of the screening period.

• History of hypersensitivity or allergy to the IMP or its excipients or any related medication.

• History of hypersensitivity or allergy to the pre-medication or its excipients or any related medication.

• History of hypersensitivity or allergy to the rescue medication or its excipients or any related medication.

• History of bronchial asthma or any other bronchospastic disease.

• History of convulsions.

• History of porphyria.

• History of cardiac arrhythmias.

• History of sudden cardiac death in the family or history of familial long QT syndrome.

• Relevant history or laboratory or clinical findings indicative of acute or chronic disease, likely to influence study outcome.

• Cytochrome P450 (CYP) 2D6 poor metabolizers (if warranted by the FDA).

• Hypomagnesemia.

• Hypothyroidism or hyperthyroidism.

• Hypokalemia.

• Subjects with narrow-angle glaucoma.

• Subjects with stenosing peptic ulcers.

• Subjects who have pyloroduodenal obstruction.

• Subjects who have symptomatic prostatic hypertrophy or bladder-neck obstruction.

• Known or previous dystonia or dyskinesia.

• Subjects with severe toxic central nervous system depression or who have experienced comatose states from any cause.

• Subjects who have Parkinson's disease.

• Donation or loss of blood equal to or exceeding 500 mL during the 8 weeks before the first administration of IMP.

• Diagnosis of hypotension made during the screening period.

• Diagnosis of hypertension made during the screening period or current diagnosis of hypertension.

• Resting pulse of > 100 beats per minute or < 40 beats per minute during the screening period, either supine or standing.

• Positive testing for human immunodeficiency virus (HIV), hepatitis B and hepatitis C.

• Positive urine screen for drugs of abuse. In case of a positive result the urine screen for drugs of abuse may be repeated once at the discretion of the investigator.

• Positive pregnancy test (female subjects).

• Hemoglobin count deviating more than 10% of the lower limit of normal.

Primary	Area Under the Curve (0-t) (AUC(0-t))	Area under the plasma concentration versus time curve from time zero to t, where t is the time of the timepoint of the last quantifiable concentration of haloperidol in the blood plasma.
