NCT ID: NCT01354353

Last Updated: 2022-09-14

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 75 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2011-05-31
• Study Completion Date: 2012-03-31

Brief Summary

This is an inpatient, open-label, multiple-dose, multicenter study to evaluate the safety and tolerability of LY2140023 given at doses expected to reflect multiples of the anticipated therapeutic exposure under clinical investigation. In the event of poor tolerability in Part A of this study Part B may be conducted to explore higher doses using titration. Participants in both Parts A and B will participate in a 9 day wash-out period of current medication (Study Days 1-9); participants coming into the study on aripiprazole will remain on their current therapy throughout.

Detailed Description

The primary objective of this study was to evaluate the safety and tolerability of escalating doses of LY2140023 in subjects with schizophrenia.

The secondary objectives of this study were:

• to characterize the pharmacokinetic (PK) parameters of LY2140023 and its active moiety - LY404039 in subjects with schizophrenia
• to explore higher doses of LY2140023 in subjects with schizophrenia for use in further regulatory studies
• to compare safety of LY2140023 to aripiprazole (ARP)
• to access changes in pharmacodynamic (PD) measures (Clinical Global Impression-Severity Scale [CGI-S], Extrapyramidal Symptoms [EPS], and Brief Psychiatric Rating Scale [BPRS])

This was an inpatient, open-label, multiple-dose, multi-center study to evaluate the safety and tolerability of LY2140023 given at doses expected to reflect multiples of the anticipated maximum therapeutic exposure under investigation.

Intervention Type: DRUG

Administered orally

Part B: LY2140023

If doses up to or equal to 400 mg BID are not tolerated, Part B of the study may be started. The dose of LY2140023 will be titrated in the same participant from highest dose that was tolerated in Part A, with the intention to reach a dose of 480 mg LY2140023.
