Study summary

BACKGROUND Chronic subdural hematoma (CSDH) is one of the most frequent reasons for cranial neurosurgical consult. There is no widely accepted medical treatment for CSDH.

This trial will investigate whether Tranexamic Acid (TXA) can increase the rate of CSDH resolution following conservative management, lower the number of required surgical procedures and decrease the rate of CSDH recurrence following surgical evacuation. TRACS is a double blind, randomized, parallel-design, placebo-controlled, phase IIB study designed to provide preliminary efficacy data as well as feasibility, safety and incidence data required to plan a larger definitive phase III trial.

METHODS Consecutive patients presenting at the Centre Hospitalier Universitaire de Sherbrooke with a recent (\< 14 days) diagnosis of subdural hematoma with a chronic component will be screened for eligibility. Exclusion criteria include specific risk factors for thromboembolic disease, anticoagulant use or contraindication to TXA. A total of 130 patients will be randomized to receive either 750 mg of TXA daily or placebo until complete radiological resolution of the CSDH or for a maximum of 20 weeks. CSDH volume will be measured on serial CT scanning. Cognitive function tests, quality of life questionnaires as well as functional autonomy assessments will be performed at enrollment, 10 weeks follow-up and 3 months post-treatment follow-up. During the treatment period, patients will undergo standard CSDH management with surgery being performed at the discretion of the treating physician. If surgery is performed, the CSDH and its outer membrane will be sampled for in vitro analysis.

The primary outcome is the rate of CSDH resolution at 20 weeks without intervening unplanned surgical procedure. Secondary outcomes include CSDH volume, incidence of surgical evacuation procedures, CSDH recurrence, cognitive functions, functional autonomy, quality of life, incidence of complications and length of hospital stay. Planned subgroup analyses will be performed for conservatively vs surgically-managed subjects and highly vs poorly vascularised CSDH.

DISCUSSION CSDH is a frequent and morbid condition for which an effective medical treatment has yet to be discovered. The TRACS trial will be the first prospective study of TXA for CSDH.

Inclusion criteria

  • CT scan demonstrating the existence of a subdural hematoma containing a chronic component
  • Diagnosis within the last 14 days

Exclusion criteria

Exclusion Criteria:

  • Acute subdural hematoma with no chronic component;
  • Active thrombotic, thromboembolic or atheroembolic disease, including deep venous thrombosis within the last six months, cerebral thrombosis within the last six months, symptomatic carotid stenosis who did not undergo surgery or stroke within the last year;
  • Past history of unprovoked deep venous thrombosis or idiopathic pulmonary embolism;
  • Known hereditary thrombophilia, including Factor V Leiden, Antithrombin III mutation, Protein C deficiency, Protein S deficiency;
  • Atrial fibrillation (unless under successful rhythm control therapy);
  • Metallic heart valve;
  • Vascular stenting procedure within the last year;
  • Cardiac or vascular surgical procedure within the last 6 months, including endarterectomy, bypass or angioplasty;
  • Ongoing investigation for suspected ;
  • Confirmed active malignancy;
  • Concomitant hormone therapy for malignancy;
  • Concomitant hormone pill;
  • Macroscopic hematuria;
  • Known or suspected tranexamic acid allergy;
  • Pregnancy or breastfeeding;
  • Concomitant use of anticoagulant medication;
  • Any concern from the attending physician.
Terms in these criteria, in plain language(2)

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.

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.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

Primary outcomes

  1. Hematoma resolution

    The rate of chronic subdural hematoma resolution without intervening unplanned surgical procedure. Specifically, if the initial management strategy chosen by the attending physician within the first 24 hours of presentation consists of expectant management, any surgical procedure leads to a failure of meeting the primary outcome. On the other hand, if the management strategy chosen by the attending physician within the first 24 hours of presentation included a surgical evacuation of the CSDH, the primary outcome is met if the control CT scan at 20 weeks demonstrates a complete radiological resolution of the CSDH. Should a second surgery be required, the subject will fail to meet the primary outcome even if the CSDH has completely resolved by 20 weeks.

    Time frame: 20 weeks

Secondary outcomes

  1. Hematoma volume

    Measured by segmentation analysis on the 20 weeks CT scan

What these dates mean
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.
No changes since tracking began. The registry record was last updated on Sep 5, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
