NCT05395351

Brief Summary

The objective of the study is to find out the in-hospital clinical outcomes among Chinese Acute Ischaemic Stroke (AIS) patients, who were treated with intravenous (IV) Recombinant Tissue Plasminogen Activator (rt-PA) within 4.5 hours of symptom onset in different age groups (18 to 80 years and above 80 years).

Study Population

Acute ischemic stroke (AIS) patients who were treated with Intravenous (IV) Recombinant Tissue Plasminogen Activator (rt-PA) or did not receive thrombolysis treatment within 4.5 hours of symptom onset, aged ≥18 years old.

You may qualify if:

  • Patient registered in the Chinese Stroke Centre Alliance (CSCA) platform from Aug 2015 to Jul 2019
  • ≥18 years old
  • Diagnosed as Acute Ischemic Stroke (AIS) at admission
  • Arrived or admitted into hospital within 4.5 hours of symptom onset
  • For patients in the iv rt-PA groups only: received IV rt-PA within 4.5 hours of symptom onset

You may not qualify if:

  • Documented Intravenous Thrombolysis (IVT) absolute contraindication
  • Key data missing (age, gender, baseline National Institutes of Health Stroke Scale \[NIHSS\], time of symptom onset, IVT treated or not, time of IV alteplase treatment)
  • Received thrombolysis agents other than IV rt-PA (urokinase, tenecteplase, recombinant plasminogen activator, prourokinase, streptokinase)
  • Received endovascular treatment
  • Received IV rt-PA after 4.5 hours of symptom onset

Limitations and Caveats

Hospital participation in the Chinese Stroke Centre Alliance (CSCA) was voluntary. To avoid selection bias, all patients were included without sampling when dataset was extracted. The larger sample size and broad geological distribution increased representativeness. Data collected by hospitals were not audited by external chart review. Data reliability depends on training for data abstractors and automated checks to identify erroneous, illogical data entries.

Data Sharing

IPD Sharing
Will not share

Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).
