Brief Summary

Single dose oral bioequivalence study of Cariprazine 1.5 mg Hard Capsules (1.5 mg Cariprazine hydrochloride) and Reagila® 1,5 mg Hartkapseln (Hard Capsules) (Cariprazine) in healthy adult human participants under fasting conditions.

Conditions

SCHIZOPHRENIA 1 (Disorder)

Outcome Measures

Primary Outcomes (2)

• The area under the plasma concentration versus time curve calculated using the linear trapezoidal rule from the zero time point to the 72 hours (AUC72)

  The statistical method for testing bioequivalence was based on the determination of the 90% confidence interval around the ratio of the Ln-transformed population means (Test/Reference) for the PK parameters AUC72

  72.00 hours

• Maximum measured plasma concentration (Cmax)

• Willing to provide written informed consent to participate in the study.
• All participants must be judged by the principal or sub-investigator or physician as normal and healthy during a pre-study safety assessment performed within 28 days of the first dose of study medication which will include:
• A physical examination (clinical examination) with no clinically significant finding.
• Additional tests and/or examinations (apart from mentioned in protocol) may be performed, if necessary, based on principal investigator discretion.
• All results will be assessed against the current laboratory normal ranges at the time of testing and a copy of the normal ranges used will be included in the study documentation.

You may not qualify if:

• History of allergic responses to Cariprazine or other related drugs, or any of its formulation ingredients.
• Have significant diseases or clinically significant abnormal findings during screening \[medical history, physical examination (clinical examination), laboratory evaluations, ECG recording, gynecological history and examination (including pelvic examination and routine breast examination) (for female participants)\].
