Comparative assessment of the absorption of a generic formulation of asenapine sublingual tablet against the innovator asenapine sublingual tablet conducted under fasting conditions in healthy male and female volunteers

A open-label, balanced, randomised, single-dose, two-treatment, three-period, three-sequence, oral bioequivalence study of asenapine sublingual tablets in a three-way crossover, partial replicate, reference scaled, comparison against the innovator asenapine sublingual tablets conducted under fasting conditions in healthy male and female volunteers

Brief summary

The objective of this study is to evaluate the bioequivalence of the test (new) formulation of 10 mg asenapine sublingual tablet relative to that of the reference formulation (innovator brand of 10 mg asenapine sublingual tablet) following oral administration of a single dose of 10 mg in healthy male and female subjects under fasting conditions

Interventions

Single dose, crossover over study design whereby each participant receives the test formulation of asenapine sublingual (1 x 10 mg) on one occasion and the innovator formulation of asenapine sublingual (1 x 10 mg) on two occasions with each dose seperated by a one week washout period. The intervention for this trial is the test formulation of asenapine. Each dose (1 x 10 mg) will be placed under the subjects tongue. Subjects will be instructed not to chew or swallow the tablet but to allow it

Single dose, crossover over study design whereby each participant receives the test formulation of asenapine sublingual (1 x 10 mg) on one occasion and the innovator formulation of asenapine sublingual (1 x 10 mg) on two occasions with each dose seperated by a one week washout period. The intervention for this trial is the test formulation of asenapine. Each dose (1 x 10 mg) will be placed under the subjects tongue. Subjects will be instructed not to chew or swallow the tablet but to allow it to dissolve completely. Investigators will complete a mouth check at frequent intervals to ensure that the medication has been taken as directed and is fully dissolved. An allergy scratch test will be carried out the night prior to dosing. Subjects are required to consume 200ml of water one hour prior to dosing. At least 10 minutes prior to dosing subjects will be asked to void their bladder and the site of the scratch test will be checked to ensure that no drug sensitivity problems have been developed. Participants are required not to eat for 10 hours before receiving each dose and to fast for approximately 4 hours after receiving each dose. Bathroom visits will be supervised to ensure no unauthorised water or food intake and for personal safety. Participants will be confined at the Clinical Site for 10 hours prior to dosing to ensure compliance can be monitored and for 24 hours after dosing. Standard meals will be consumed at the Clinical Site with no additional food intake allowed. Alcohol breath testing will be performed upon each participant reporting to the Clinical Site 10 hours prior to dosing. Pre and post study laboratory tests will be completed to assess the healthy of participants along with HIV, Hepatitis and drugs of abuse testing. An allergy scratch test to determine sensitivity will be carried out during medical screening and prior to receving each asenapine dose.
