About this study

Official title: A Randomized, Open-label, Single Oral Dose, Two-period, Cross-over Trial to Evaluate the Pharmacokinetics of Pelubiprofen-Tramadol (DW-1021) Controlled Release Film Coated Tablets (Pelubiprofen 45mg-Tramadol 45.9mg Salt) (Test Drug) in Comparison With the Co-administration of Each of Pelubi CR 45mg Controlled Release Film Coated Tablets (Pelubiprofen 45mg) and Zytram CR 75mg Controlled Release Film Coated Tablets (Tramadol HCl 75mg) in Healthy Adult Vietnamese Male Subjects Under Fasting Condition

This is a Phase 1, randomized, open-label, single-dose, two-period, cross-over study to evaluate the pharmacokinetics (PK) of DW-1021, a fixed-dose combination tablet containing Pelubiprofen 45 mg and Tramadol 45.9 mg (as a salt), in healthy adult Vietnamese male volunteers. The study compares DW-1021 with the co-administration of two reference drugs: Pelubi CR 45 mg (Pelubiprofen) and Zytram CR 75 mg (Tramadol HCl), under fasting conditions.

A total of 14 eligible participants will be randomly assigned to receive either the test drug followed by the reference drugs, or vice versa, with a 14-day washout period between the two dosing periods. Blood samples will be collected over a 48-hour period after each administration to evaluate drug concentrations. The main purpose is to assess and compare the rate and extent of absorption (Cmax, AUC) of the test and reference products.

The study is sponsored by Haiphong University of Medicine and Pharmacy in collaboration with Daewon Pharmaceutical Co., Ltd. It is conducted under ethical approval by the National Ethics Committee in Biomedical Research of Vietnam.

Read the detailed description

This clinical trial is designed to evaluate and compare the pharmacokinetic characteristics of DW-1021, a fixed-dose combination of Pelubiprofen and Tramadol in salt form (Pelubiprofen 45 mg - Tramadol 45.9 mg), with the co-administration of the individual components-Pelubi CR 45 mg (controlled release Pelubiprofen) and Zytram CR 75 mg (controlled release Tramadol hydrochloride)-in healthy adult male Vietnamese volunteers under fasting conditions.

This is an open-label, randomized, single-dose, two-treatment, two-period, two-sequence crossover study. Fourteen eligible participants will be randomized into two sequences: Test-Reference (TR) and Reference-Test (RT), with each dosing period separated by a 14-day washout. Study drugs will be administered in a fasted state, and blood samples will be collected at multiple time points up to 48 hours post-dose for pharmacokinetic analysis.

The primary PK parameters include Cmax and AUCt. Secondary PK parameters include Tmax, AUC∞, and t1/2. Safety will be monitored through assessment of adverse events, vital signs, clinical laboratory tests, and physical examinations throughout the study.

The trial is sponsored by Haiphong University of Medicine and Pharmacy. Analytical testing of plasma concentrations will be performed by Invites Bio-Core, and CRO support is provided by Big Leap Clinical Research Support JSC. The study is approved by the National Ethics Committee in Biomedical Research of Vietnam (Approval No. 277/CN-HĐĐĐ, dated 12/12/2024). This study was additionally approved for protocol amendments by the Vietnamese Ministry of Health under Decision No. 3840/QĐ-BYT, dated December 19, 2024.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • DW-1021Drug

    Also called Pelubiprofen 45 mg - Tramadol 45.9 mg salt combination, Pelubiprofen-Tramadol fixed-dose combination

    DW-1021 is a fixed-dose combination tablet containing Pelubiprofen 45 mg and Tramadol 45.9 mg (as a salt), formulated as a controlled-release film-coated tablet. It is administered as a single oral dose with 150 mL of water under fasting conditions for the evaluation of pharmacokinetics in healthy adult male volunteers.

  • Pelubi CR + Zytram CRDrug

    Also called Pelubiprofen 45 mg controlled-release tablet, Tramadol HCl 75 mg controlled-release tablet

    The reference treatment consists of two separate controlled-release film-coated tablets: Pelubi CR (Pelubiprofen 45 mg) and Zytram CR (Tramadol HCl 75 mg). These are co-administered as a single oral dose with 150 mL of water under fasting conditions to compare the pharmacokinetic profile against the fixed-dose combination DW-1021.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximum plasma concentration (Cmax)

    Cmax represents the peak plasma concentration of the drug after administration. It is used to compare the rate of absorption between the test and reference products.

    Measured: 0 to 48 hours post-dose in each period

  2. Area under the plasma concentration-time curve from time 0 to the last measurable concentration (AUCt)

    AUCt is a pharmacokinetic parameter representing the total drug exposure from administration to the last quantifiable time point. It is used to compare the extent of absorption between DW-1021 and the reference drugs.

    Measured: 0 to 48 hours post-dose in each period

Secondary outcomes (3)
  1. Area under the curve extrapolated to infinity (AUC∞)

    AUC∞ represents the total drug exposure over time, extrapolated beyond the last measured concentration. It helps assess complete systemic exposure.

    Measured: 0 to 48 hours post-dose in each period

  2. Terminal elimination half-life (t1/2)

    The time it takes for the plasma concentration of the drug to decrease by 50%. It is used to understand the drug elimination kinetics.

    Measured: 0 to 48 hours post-dose in each period

  3. Time to reach maximum plasma concentration (Tmax)

    Tmax is defined as the time point at which the maximum plasma drug concentration is observed following drug administration. It is used to compare the absorption rate between DW-1021 and the reference products.

    Measured: 0 to 48 hours post-dose in each period

Model description
This is a randomized, open-label, single-dose, 2-treatment, 2-period, 2-sequence (2x2) crossover study conducted under fasting conditions. Fourteen healthy male volunteers will be randomly assigned to one of two sequences: Test-Reference (Group A) or Reference-Test (Group B), with a 14-day washout period between dosing periods. The test drug (DW-1021, Pelubiprofen 45 mg - Tramadol 45.9 mg salt) or the reference drugs (Pelubi CR 45 mg and Zytram CR 75 mg) will be administered orally with 150 mL of water after at least 10 hours of fasting. Blood samples will be collected up to 48 hours post-dose in each period for pharmacokinetic evaluation.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 28 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Nguyen Thi Thu Phuong, MD, PhD (+84936685007, nttphuong@hpmu.edu.vn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximum plasma concentration (Cmax) (time frame: 0 to 48 hours post-dose in each period). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07032558, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
