Clinical Trial Summary

15 stable patients diagnosed with schizophrenia take 100 mg of VLT-015 once a day, 200 mg of VLT-015 once a day and 200 mg of VLT-015 on two consecutive days with an interval of 24 hours between doses. PK parameters are measured, tolerability and safety of the product are evaluated.

Description:

At stage 1, 15 stable patients diagnosed with schizophrenia take 1 tablet of VLT-015 (100 mg) followed by blood sampling to measure the level of the active substance and its main metabolite within 72 hours. After that patients have 3 days washout period. At the second stage, the same 15 patients take two 100 mg tablets of VLT-015 (200 mg) followed by blood sampling to measure the level of the active substance and its main metabolite within 72 hours. Then patients have the same 3 days washout period. At stage 3, the same patients take 2 tablets of VLT-015 (200 mg) consecutively for 2 days with 24-hours interval followed by blood sampling to measure the level of the active substance and its main metabolite within 96 hours. PK parameters are measured, tolerability and safety of the product are evaluated.
