Food Effect on PK of DW-1021 (Pelubiprofen 45 mg / Tramadol 45.9 mg) in Healthy Adults

Официальное название

A Randomized, Open-label, Single Oral Dose Clinical Trial to Evaluate the Food Effect on the Pharmacokinetics of Pelubiprofen-Tramadol (DW-1021) Controlled Release Film Coated Tablet (Pelubiprofen 45mg / Tramadol 45.9mg) After Oral Administration in 14 Healthy Adult Vietnamese Male Subjects Under Fed and Fasting Conditions

Обзор

This is a Phase 1, open-label, single-dose crossover study designed to evaluate the effect of food on the pharmacokinetics of DW-1021, a fixed-dose combination tablet containing pelubiprofen 45 mg and tramadol 45.9 mg. Fourteen healthy adult Vietnamese males will each receive DW-1021 once under fasting conditions and once under fed conditions, with a 14-day washout period in between. Blood samples will be collected to assess how food intake affects the absorption and exposure levels of both active ingredients. Safety, including adverse events, laboratory results, vital signs, and ECGs, will be closely monitored throughout the study.

Подробное описание

DW-1021 is a fixed-dose combination tablet containing pelubiprofen, a nonsteroidal anti-inflammatory drug (NSAID), and tramadol, a centrally acting analgesic. Combining these two agents is expected to provide multimodal pain relief by targeting both peripheral and central pain pathways while potentially reducing opioid-related side effects.

This Phase 1 study is being conducted to evaluate how a standard high-fat meal affects the rate and extent of absorption of pelubiprofen and tramadol when administered together in DW-1021. A randomized, open-label, two-period, two-sequence crossover design is used to allow each subject to serve as his own control, improving the reliability of the pharmacokinetic comparison between fasting and fed states.

Each of the 14 healthy adult male volunteers will receive a single dose of DW-1021 under fasting conditions in one period and under fed conditions in the other, with a sufficient washout period to prevent carryover effects. Intensive blood sampling will be performed after each dose to measure plasma concentrations of pelubiprofen, its active metabolite (trans-OH-pelubiprofen), tramadol, and O-desmethyl-tramadol. Safety will be monitored throughout, including recording of adverse events, laboratory tests, vital signs, and ECGs.

The data generated will help determine whether food intake has a clinically significant impact on the pharmacokinetic profile of DW-1021 and will support future dosing recommendations and product labeling.
