RCT, Blinded, 2-Arm Efficacy Study of IP and Placebo in Patients With Chronic Pain Related to Osteoarthritis of the Knee
United States, Taiwan500 participantsStarted 2021-12-10
Plain-language summary
It is a Phase III efficacy study as the title 'A randomized, double-blind, parallel-arm study comparing the efficacy of investigational product "Ibuprofen Modified-Release Tablets 800 mg" and placebo in patients with chronic pain related to osteoarthritis of the knee.' The primary objective is to determine the analgesic efficacy of orally administered IBUMR in patients with osteoarthritis (OA) of the knee.
The Secondary objectives are to compare the treatment effect on patient pain, function and stiffness between IBUMR- and placebo-treated patients as measured by the Western Ontario and McMaster Osteoarthritis Index (WOMAC), to compare the treatment effect on Patient Global Assessment on Disease Activity between IBUMR- and placebo-treated patients, to compare the treatment effect on Investigator's Global Assessment on Disease Activity between IBUMR- and placebo-treated patients, to compare the use of analgesic rescue medicine between IBUMR- and placebo-treated patients, to determine the safety profile of IBUMR.

Inclusion criteria
. Male and female patients ≥18 years of age at the screening visit.
. Patients diagnosed with symptomatic OA of the knee based on the American College of Rheumatology (ACR) clinical criteria and have an American Rheumatology Association (ARA) functional class rating of I, II, or III (1), for ≥ 3 months prior to date of screening; with recent (≤ 6 months) radiographic evidence of tibiofemoral OA: ≥ Grade 2 on the Kellgren \& Lawrence scale. (In cases where both knees are affected, the most painful knee joint is selected as the target knee for study evaluation).
. Patients had been prescribed NSAIDs or acetaminophen to treat their OA-related pain for at least 3 months prior to the screening visit.
. Following discontinuation of analgesic medication (a washout period of at least 5 times the half-life (prior to Day -7), plus a subsequent additional 7 days prior to Baseline visit (Day -7 to Day-1), patients must have a reported pain score of at least 40 mm for WOMAC Pain intensity question: 'walking on a flat surface' at Baseline Visit.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Change from baseline in the WOMAC visual analogue 3.1 Pain intensity subscale, over 12 weeks of treatment. [Time frame: Baseline week up to Week 12]
Timeframe: at baseline week (Day -6 to Day 1) and at Day 8, 15, 22, 29, 43, 57 and Week 12 (Day 79 to Day 85).
. Subjects are willing to comply with protocol-stated requirements, instructions and restrictions, followed by understanding and signing the written informed consent form or legal representative if he/she is under the statutory age of consent as per the local authority.
Exclusion criteria
. Patients with a history of gastroduodenal perforations and/or obstructions; gastric and/or duodenal surgery; recent (≤ 6 months) active gastrointestinal (GI) ulceration; inflammatory bowel disease; GI bleeding in the past year.
. Patients with a history of congestive heart failure, coronary artery disease, renal artery stenosis or recent (within 1 year) myocardial infarction, angina, stroke, or transient ischemic attack and/or with uncontrolled hypertension.
. Patients with moderate to severe hepatic impairment (alanine aminotransferase \[ALT\] or aspartate transaminase \[AST\] concentrations \> 2.5 times the upper limit of normal).
. Patients with a medical condition (e.g., a cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal, endocrine \[adrenal hyperplasia\], immunologic, dermatologic, neurologic, oncologic, or psychiatric) or a significant laboratory abnormality that, in the Investigator's opinion, would jeopardize the safety of the patient or is likely to confound the study measurements.
. Patients receiving ongoing opioid therapy for their OA-related pain; or requiring ongoing use of analgesic therapy for other indications, anticoagulants, psychotherapeutic agents, aspirin at daily doses greater than 325 mg, statin-class hypolipidemic agents at doses that have not been stabilized, or other treatments known to interfere with pain perception. (Note: 'stabilized' is defined as being used for at least 3 months).
. Patients who have received intra-articular injection of corticosteroids, hyaluronic acid or platelet-rich plasma in the target knee within 6 months prior to the screening visit (within 1 year for long-acting formulations); or have received opioid medication within 14 days prior to the screening visit.
. Patients who are unable to be prescribed NSAIDs or are known or suspected to have hypersensitivity to study medication or their excipients.
. Patients who have participated in investigational drug trials and took any investigational therapy within 90 days or a time of 5 half-lives prior to the study dosing.
