About this study

Official title: Phase 2 Study of Rt-PA Dose-effect Relationship on ICH Evacuation

The purpose of this trial is to determine the optimal dose of rt-PA in the treatment of intracerebral hemorrhage (ICH) using a combination of minimally invasive surgery and clot lysis with rt-PA。

Read the detailed description

The minimally invasive surgery (MIS) plus recombinant tissue plasminogen activator (rt-PA) is one of the best choices in the treatment of a large-scale deep supratentorial intracerebral hematoma. It uses hardware access technology, in a relatively short time to enter the hematoma center with favourable accuracy and safety.

The dose of rt-PA range from 0.3 mg to 4.0 mg in different research。We propose to determine the optimal dose of rt-PA with three dose control groups.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • YL-1 type of intracranial hematoma puncture needleDevice

    Also called aspiration drainage

    YL-1 type of intracranial hematoma puncture needle(Pat. NO.is ZL:93244252•8) was originated by Beijing WanTeFu Medical Apparatus Co.Ltd in 1997. With integration of needle and bur drill it is designed as hard tunnel.By the technique of skull self-holding, the puncture needle can being fixed in the target of haematoma for several days.This technique is convenient, simple and safe. To position haematoma's location, drills 3 millimeter holes in the localization point of puncture, then insert the drainage tube to inhale hematoma, gives the filament resolver interrupted for liquefication drainage afterward.

  • rt-PADrug

    Also called recombinant tissue plasminogen activator

    Up to 4 doses of 0.3~1.0 mg of rt-PA will be administered through the catheter that was placed directly into the intracerebral hemorrhage using minimally invasive surgery.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 16 Jun 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

rate of clot size removal (time frame: baseline to 24 hours(±12) post the last dose of rt-PA). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02472574, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Jun 2015.
