Overview

Primary pontine hemorrhage (PPH) is not common but is the most catastrophic subtype of intracerebral hemorrhage, with acute mortality between 30% and 60%. For severe PPH, defined as Glasgow Coma score (GCS) <8 and hematoma volume≥5ml, the mortality rate is as high as 80-100%. Guidelines from the American Heart Association and European Stroke Organization do not make definite specifications. More than a century after Finkelnburg first explored the brainstem for hematoma, however, plenty of researches have shown surgery can save lives and improve the prognosis for selective patients and can be an effective and safe treatment. This study is proposed to validate the safety of surgical treatment in severe primary pontine hemorrhage.

Description

The study is being conducted from Jan 2022 to Nov 2024 in 20 neurosurgical units. This STIPE trial is an investigator-initiated, parallel (3:1 to surgical HE or MT), multi-centre, randomized controlled open-label trial following the Consolidated Standards of Reporting Trials (CONSORT) guidelines and will be conducted from Jan 2022 to Nov 2024 in 20 Tertiary hospitals in China. The flow chart of the clinical trial is presented in Figure 1. Neurosurgeons involved in the study are senior investigators with good clinical experience in sPPH management. Moreover, all investigators are well trained centrally according to the requirements.

Eligibility

Inclusion Criteria:

  1. Clinical diagnosis of PPH: patients have acute hemorrhage mainly in pons with a definite history of hypertension.
  2. GCS 5~7 and HV≥5ml on admission (the HV in intraventricular system being excluded).
  3. Family members consenting to randomize and signing informed consent form (ICF).
  4. Time from onset to admission less than 24 hours.
  5. Age:18 years or older.

Exclusion Criteria:

  1. Structural lesions such as brainstem cavernous malformation, arteriovenous malformation, aneurysm, tumor apoplexy.
  2. GCS≥8 and HV<5ml.
  3. Time from onset to admission over 24 hours.
  4. Patients with platelet count < 100,000, International Normalized Ratio (INR)> 1.4, or an elevated prothrombin time (PT) and activated partial thromboplastin time (APTT).
  5. Multiple ICH.
  6. Accompanying hydrocephalus that requires surgical management
  7. Irreversible brainstem failure (bilateral fixed, dilated pupils and extensor motor posturing, GCS≤4).
  8. A previous history of ICH.
  9. Any serious concurrent illness that would interfere with the safety assessments including hepatic, renal, gastroenterologic, respiratory, cardiovascular, endocrinologic, immunologic, and hematologic disease.
  10. Pregnant patients.
  11. Patients' family members refuse HE.
  12. Any other condition that the investigator believes would present a significant hazard to the subject if the investigational therapy were initiated.
  13. Participating in another simultaneous trial of ICH treatment.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
