A Pharmacokinetic Trial of the OPB-111077 Current Formulation Versus the Modified Formulation by Single Administration in Healthy Adult Male Subjects

JRCT ID: jRCT2071230033

Registered date:27/06/2023

Basic Information

• Recruitment status: Not Recruiting
• Health condition(s) or Problem(s) studied: Diffuse large B-cell lymphoma
• Date of first enrollment: 30/08/2023
• Target sample size: 56
• Study type: Interventional

Intervention(s)

A single oral dose of an antiemetic drug (Nasea OD Tablets 0.1 mg) will be administered at 1 hour (acceptable window: 55 to 60 minutes) prior to IMP administration with approximately 150 mL of water. At 30 minutes (acceptable window: 25 to 30 minutes) after the start of breakfast, a single oral dose of the IMP scheduled for each cohort and group will be administered with approximately 150 mL of water.
The dose for Cohort 1 is 100 mg for the current formulation and 50 mg for the modified formulation and while confirming the tolerability and safety of each of the current and modified formulations, the sponsor will decide whether to proceed to the next cohort based on the procedure for advancing to the next cohort.
The dose of the current formulation in Cohort 2 and Cohort 3 is 200 mg and 400mg. The sponsor will determine the dose of the modified formulation to be administered in Cohort 2 and Cohort 3 based on the pharmacokinetic data for the unchanged drug up until 96 hours postdose.
