Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43925   clinical trials with a EudraCT protocol, of which   7306   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of this study is to determine whether methotrexate is an effective treatment for relieving pain in knee OA.
    E.2.2Secondary objectives of the trial
    The secondary objective is to determine whether methotrexate is a cost effective treatment for knee OA.
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    MRI sub study: The objective of the MRI substudy is to examine whether methotrexate reduces inflammation within the osteoarthritic knee joint and if this is related to symptom change and is a predictor of response. MRI of the signal knee will be performed at baseline and six months (24 weeks). Participation in the MRI substudy is optional.
    Biological sub study: The objective of the biological substudy is to analyse markers of inflammation in the blood to determine which markers/genes are important in osteoarthritis and the response to treatment. Biological samples (blood and urine) will be taken at baseline and six months (24 weeks). Participation in the biological substudy is optional.
    E.3Principal inclusion criteria
    Patients to be included must meet the following criteria:
    1. Fulfil clinical ACR Criteria for knee OA.
    2. Knee pain on most days in the last 3 months.
    3. Insufficient pain relief from, inability to tolerate, or contra-indication to oral and/or topical NSAIDs and/or opioids. Moderate to severe pain of the signal knee as defined by a score of ≥40mm on a VAS (0-100mm) using the question “On average, how would you rate your knee pain during the last 3 months?”.
    4. Knee pain is the predominant pain condition.
    5. Patient able to identify a ‘signal’ painful knee (either the most painful knee or selected from equally painful knees).
    6. A radiograph (X-Ray) of the signal knee within the last 2 years with changes consistent with tibiofemoral OA.
    7. No change in the average weekly dose of oral/topical analgesics (including NSAIDs) for at least 4 weeks.
    8. Has used chondroitin or glucosamine for at least 3 months with no change to the average weekly dose, is not using or is willing to stop using if recently started.
    9. All male and female subjects biologically capable of having children must agree to use a reliable method of contraception for the duration of the study and 24 weeks after the end of the study period. Acceptable methods of contraception are surgical sterilisation, oral, implantable or injectable hormonal methods, intrauterine devices or barrier contraceptives.If female and have potential for child bearing then a negative pregnancy test must be performed prior to starting treatment.
    10. The patient must be able to adhere to the study visit schedule and other protocol requirements.
    11. The patient must be capable of giving informed consent and the consent must be obtained prior to any screening procedures.
    12. All patients must have had a chest radiograph (X-Ray) within the last 6 months.
    13. Aged >/= 18 years
    E.4Principal exclusion criteria
    Patients will be excluded from this study for any of the following reasons:
    1. The presence of any inflammatory arthritis (e.g. gout, reactive arthritis, rheumatoid arthritis, psoriatic arthritis, seronegative spondylarthropathy, previous diagnosis of pseudogout in target joint with proven crystals on joint aspiration or elevated CRP at time of knee arthritis flare) or fibromyalgia.
    2. Use of intra-articular (IA) hyaluronic acid in the signal knee within the 4 months preceding enrolment in the study.
    3. Use of IA, IM or oral corticosteroids in the 3 months preceding enrolment.
    4. Use of other anti-synovial agents (e.g. hydroxychloroquine or sulphasalazine) in the 2 months preceding the study.
    5. Significant knee injury or any knee surgery within the 6 months preceding enrolment in the study.
    6. A history of partial or complete joint replacement surgery in the signal knee at any time, listed for knee surgery or anticipating knee surgery during the study period.
    7. Commencement of physiotherapy or non-pharmacological knee OA treatment in the 2 months preceding the study.
    8. The presence of non-OA causes of pain in the signal knee e.g. referred hip pain, osteonecrosis.
    9. Women who are pregnant, breast-feeding, or men or women planning pregnancy within 18 months after screening (i.e. approximately 6 months following last study medications).
    10. Use of any investigational (unlicensed) drug within 1 month prior to screening or within 5 half-lives of the investigational agent, whichever is longer.
    11. Have current signs or symptoms of severe, progressive or uncontrolled renal, hepatic, haematological, gastrointestinal, endocrine, pulmonary, cardiac, neurologic, cerebral disease, or active current infection.

    14. Planned need for live vaccination during 12 months of study (e.g. for foreign travel) with exception of Zostavax® which is permissible.
    15. Poor tolerability of venepuncture or lack of adequate venous access for required blood sampling during the study period.
    16. Melanoma, squamous cell carcinoma or non-skin cancer in the past 3 years.
