Study summary

The present study aims to compare the efficacy and the safety of MaioRegen Prime to Debridement (SSOC) in patients with deep osteochondral lesions of the knee joint. The foreseen population involves patients with osteochondral lesions with different etiology, dimension, shape, and location.

The evaluation will be performed through clinical, subjective and objective assessments.

Read the detailed description

This is multicenter, prospective, randomized clinical trial, subjects will be randomized (2:1) to MaioRegen Prime or debridement.

All randomized patients will be followed with post-operative visits at 15 days, 6 weeks, 3, 6, 12, 18 and 24 months after surgery and annually post-24 months visit (until last patient reaches 24 months).

During screening period and at follow-up visits commonly used specific scores will be evaluated: IKDC Subjective Knee Evaluation Form, IKDC Knee Examination Form, KOOS, Tegner Score, VAS pain, PROMIS-29, ICRS Cartilage Repair Assessment and MRI related scores.

Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. Superiority of MaioRegen Prime vs Debridement

    The primary endpoint is the success rate defined as a composite binary endpoint, where a patient is a success if they meet all of the following criteria: * At least a 15 points IKDC increase at 24 months * Lack of SAE related to MaioRegen treatment or debridement during the 24-month follow-up * Lack of related re-intervention after MaioRegen treatment or debridement during the 24-month follow-up

    Time frame: baseline, 24 months

Secondary outcomes

  1. International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Score at 24 months of MaioRegen Prime compared to debridement

    Subjective, knee-specific rating scale that is considered one of the most reliable assessment tools in the evaluation of knee pathologies. All questions examines 3 categories: symptoms, sports activity, and knee function. The IKDC Subjective Knee Evaluation Form is graded by adding the results of each item's scores, and then converting the result to a scale from 0 to 100. Higher scores indicate higher levels of function and lower levels of symptoms, (i.e., a better outcome).

    Time frame: baseline, 24 months

  2. Rate of responder in IKDC Subjective Knee Evaluation at 24 months of MaioRegen Prime compared to debridement as defined as improvement in IKDC Subjective Knee Evaluation of ≥15 points

    The new IKDC Subjective Knee Evaluation Form, published in 2000, is considered one of the most reliable assessment tools in the evaluation of knee pathologies. All questions examines 3 categories: symptoms, sports activity, and knee function. The IKDC Subjective Knee Evaluation Form is graded by adding the results of each item's scores, and then converting the result to a scale from 0 to 100. Higher scores indicate higher levels of function and lower levels of symptoms, (i.e., a better outcome).

    Time frame: baseline, 24 months

  3. Proportion of patients without SAEs related to MaioRegen treatment or debridement treatment during the 24-month follow-up period

    Time frame: baseline, 24 months

  4. Proportion of patients without related re-intervention after MaioRegen treatment or debridement treatment at 24 month follow-up period

    Time frame: baseline, 24 months

  5. Change from baseline in average overall KOOS score (Knee Injury and Osteoarthritis Outcome Score)

    KOOS score consists of 5 subscales and covers: pain (9 items), symptoms (7 items, two of which are related to stiffness), functions and activities of daily living (17 items), physical function, sports and leisure activities (5 items) and quality of life in relation to the knee (4 items). Each question uses a 0 (no problem/difficulty) to 4 (extreme problem/difficulty) response, which is then converted into the final 0-100 score for each subscale, indicating the percentage of the total possible score achieved, with 0 representing extreme knee problems (i.e., worse outcome) and 100 representing no knee problems (i.e., better outcome).

    Time frame: baseline, 12, 18, and 24 months

  6. Change from pre-injury and from baseline in Tegner score

    Tegner activity level scale allows to know the level of physical activity carried out by the patients. Tegner's activity scale classifies the activity according to work and sports activities on a scale from 0 to 10, where 0 is being on sick leave/disabled due to knee issues, and 10 is elite, international competitive sports.

    Time frame: baseline, 12 months, 18 months, 24 months

  7. Change from baseline in IKDC (International Knee Documentation Committee) Knee Examination Objective Form

    The IKDC objective examination form uses a 0-100 scale, calculated by summing seven parameters related to knee function. The presence of effusions and degree of knee motion are assessed; the worst value of any of these parameters determines the final IKDC grade. There are four grades (A, B, C, D) that identify a knee rated as normal, near normal, abnormal, and severely abnormal, respectively.

    Time frame: baseline, 12 months, 18 months, 24 months

  8. Change from baseline in VAS (visual analogue scale) pain

    The VAS scale is a 0-cm line tool to measure pain intensity, with "no pain" at 0 and "worst pain imaginable" at 10, where patients mark their pain level

    Time frame: baseline, 12 months, 18 months, 24 months

  9. PROMIS-29 (Patient-Reported Outcomes Measurement Information System): Patient's QOL (quality of life) improvement

    The PROMIS-29 uses a T-score metric (mean 50, SD 10) to assess 7 domains (Physical Function, Fatigue, Depression, Anxiety, Pain Interference, Sleep Disturbance, and Social Participation) with 4 questions with an additional pain intensity numeric rating scale (NRS, 0-10 score). There is no total score, but each axis forms its own score.

    Time frame: baseline, 12 months, 18 months and 24 months

  10. MRI evaluation: MOCART (Magnetic Resonance Observation of Cartilage Repair Tissue) 2.0 Knee Score

    MOCART 2.0 score allows the assessment of both cartilage tissue repair and the structures surrounding it. It is a 0-100 point MRI-based system for evaluating cartilage repair, updating the original MOCART by focusing on nine key variables like defect filling (in 25% increments), integration to native cartilage, surface, signal intensity, bony changes (overgrowth/defect), marrow edema, and subchondral cysts. 100 represents the best score and a score of 0 represents the worst score.

    Time frame: baseline, 12 months, 24 months

Other outcomes

  1. Safety Outcome

    Adverse Events rate per type, severity, seriousness, and relatedness to the treatment, including Serious Adverse Events and Serious Adverse Device Effect, Adverse Device Effect, Unanticipated Adverse Device Effect, Re-operations, Complaint and Treatment Failures up to 24 months will be evaluated and adjudicated by CEC members.

    Time frame: 24 monhs

Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
