Study summary

MAGIC-MT study is multi-center, prospective, randomized (1:1) controlled trial designed to show that additional MMA embolization with Onyx in patients with non-acute symptomatic subdural hematoma(SDH) results in reduced hematoma recurrence in surgically treated patients/ reduced hematoma progression in conservatively managed patients.

Read the detailed description

The objective of this study is to show that additional MMA embolization with Onyx in patients with non-acute symptomatic subdural hematoma(SDH) results in reduced hematoma recurrence in surgically treated patients/ reduced hematoma progression in conservatively managed patients.

Inclusion criteria

  1. Patients with symptomatic non-acute SDH with mass effect (i.e., chronic or subacute SDH)

    1. Mass effect refers to a shift in midline structure or deformation of local cerebral cortex due to SDH.
    2. Symptomatic defined as neurological symptoms, such as headache, short-term cognitive dysfunction, language disorder or aphasia, gait instability, decreased muscle strength, sensory disturbances, epileptic seizure, etc.
  2. Age ≥18 years;
  3. Pre-morbid mRS score 2;
  4. Form (ICF) signed by patient or guardian.

Exclusion criteria

Exclusion Criteria:

  1. Radiographic imaging indicating massive cerebral infarction with corresponding symptoms;
  2. Required craniotomy or craniotomy with small bone flap to remove SDH;
  3. Emergency SDH removal/drainage;
  4. Bilateral SDH with unknown origin of symptoms;
  5. Anatomical variations that may affect the safety of MMA embolization (e.g., prominent middle MMA-ophthalmic artery anastomosis);
  6. Intractable coagulation dysfunction or abnormal count and function (pre-operative [INR] > 1.5 and/or platelet count \< 80109/L);
  7. to cerebral angiography, such as allergy to iodinated contrast agents, renal insufficiency ( \< 30 ml/min), etc.;
  8. Computed tomography (CT) or magnetic resonance imaging (MRI) showing intracranial space-occupying lesions;
  9. Pregnancy or planning to become pregnant;
  10. Serious or fatal coexisting disease that may prevent improvement of conditions or completion of follow-up;
  11. \< 1 year;
  12. Recent operation unrelated to this study or investigators believe that they will be at higher risks if antiplatelet and/or anticoagulant drugs are discontinued;
  13. Inability to complete follow-up as required by the protocol;
  14. Patients participating in other clinical trials;
  15. Prior surgery or interventional therapy on target SDH;
  16. Inability to complete MMA embolization before trepanation and drainage.
Terms in these criteria, in plain language(6)

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.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
