Brief summary

This project is testing the safety and pharmacokinetics of a single oral dose of a new drug called GBP-088 when given with and without food. GBP-088 is being developed for the treatment of recurrent kidney stones. You may be eligible for this study if you are a healthy adult man or woman aged between 18 and 55 years old. You will receive a single oral dose of active study drug on Day 1 under fasted conditions. After a 4 day washout period you will receive the same oral dose of active study drug given after eating a high fat, high calorie meal. It is hoped that this research will help determine the safety of GBP-088 when given to healthy men or women so that it can be tested in patients with recurrent kidney stone disease

Interventions

Approximately 8 healthy men or women will be enrolled in the food effect part of this study (Cohort SC-6). In Cohort SC-6 the participants will only receive GBP-088. There will be no participants receiving placebo. Cohort SC-6 receives a single dose of GBP-088 twice. The first dose will be following an overnight fast of at least 10 hours. The second dose will be given after a 4 day washout and following a standard high fat and high calorie meal. The meal will contain about 1000 calories with

There will be no participants receiving placebo. Cohort SC-6 receives a single dose of GBP-088 twice. The first dose will be following an overnight fast of at least 10 hours. The second dose will be given after a 4 day washout and following a standard high fat and high calorie meal. The meal will contain about 1000 calories with approximately 150 protein calories, 250 carbohydrate calories and 600 fat calories. Participants will be required to refrain from fluids for an hour before dosing and an hour after each dosing. The dose to be used in SC-6 will not be any higher than previously tested single doses and will not exceed 2000mg.
