The first part of VK0214-102 will include the first 2 dose cohorts and placebo, which will be dosed in parallel (up to N=24). The first 2 doses used in these cohorts will be 20 mg QD and 40 mg QD for 28 days. A Dose Level Review Team (DLRT) meeting will be held at the end of the first 2 parallel doses.~The DLRT will review safety, tolerability, and preliminary efficacy data from cohort 1 and 2. If the data analyzed show that the first 2 doses are safe and well tolerated the DLRT may make a recommendation for proceeding to commence dosing in the third dose cohort.~Based upon outcomes in Cohorts 1 and 2, the sponsor may decide to include a third dose cohort. Before screening may be initiated in Cohort 3, data to support dosing in this cohort will be submitted to the FDA, together with the amended protocol and the dosing recommendation of the DLRT.
Subjects will be administered multiple doses of VK0214 in a cohort dose escalation process. A total of up to 36 subjects will be enrolled in the study, into one of three dose cohorts. For each cohort, up to 12 subjects will be randomized to receive VK0214 or placebo in a 3:1 ratio so that there will be a total of up to 9 subjects for each of the active doses and up to 3 subjects dosed with placebo in each cohort.
