About this study
Official title: Risk Assessment Model for Ischemic Stroke Endpoint Events Combining Multi-dimensional Traditional Chinese Medicine(TCM) and Modern Medicine Indicators: a Registry Study (Inlaid With a Prospective Cohort Study to Evaluate the Effectiveness of Qilong Capsules)
The present study aims to develope a risk assessment model of ischemic stroke endpoint events combining multi-dimensional traditional Chinese medicine(TCM) indicators with modern medicine indicators. The proposed study is a registry study based participant survey conducted in 7 hospitals nationwide in China. After obtaining informed consent, a total of 3000 study patients diagnosed with ischemic stroke will be recruited. 1-year follow-ups are carried out on-site in hospitals and by telephone to track endpoint events. At the same time, we conducted a prospective, multicenter, real-world longitudinal cohort study at 7 hospitals in China to investigate the clinical effectiveness of Qilong capsule (QLC) combined with CT for IS with Qi deficiency and blood stasis syndrome.
Read the detailed description
Stroke is characterized by high incidence and high rates of recurrence and other endpoint events. Risk assessment is important for secondary prevention of ischemic stroke. To date, no study has been conducted to evaluate the risk of ischemic stroke endpoint events by establishing risk accessment models combining TCM and modern medicine indicators.
The present study aims to develope a risk assessment model of ischemic stroke endpoint events combining multi-dimensional TCM indicators with modern medicine indicators. The proposed study is a registry study based participant survey conducted in 7 hospitals nationwide in China. After obtaining informed consent, a total of 3000 study patients diagnosed with ischemic stroke will be recruited. 1-year follow-ups are carried out on-site in hospitals and by telephone to track endpoint events. Comparative analysis of prevalence of endpoint events and other TCM or modern medicine features in different groups is conducted using frequency analysis and chi-squared tests, and expressed with composition ratios. Comparative analysis of quantitative scores of the scales and related syndromes or symptoms is conducted using rank-sum test. Correlation analysis of endpoint events and TCM or modern medicine factors will be performed using multivariate Cox proportional hazard model.
Participants in the exposed group were treated with QLC, and those in the non-exposed group were not treated with QLC. All participants in two groups received standard treatment without restriction. The intervention course of QLC was 12 weeks. All participants returned for in-person follow-up visits at the 12th week and 24th week. Primary outcome measures included a modified Rankin Scale (mRS), the National Institute of Health Stroke Scale (NIHSS), and the Barthel Index (BI). Secondary outcome measures included TCM syndromes (Qi deficiency syndrome score, blood stasis syndrome score), psychological index (self-rating depression scale, SDS; self-rating anxiety scale, SAS), blood lipid index, blood coagulation index, and homocysteine. Multiple imputations were used for any missing data. Propensity score matching (PSM) was used to deal with any confounding factors (age, gender, scale score, etc.). Rank alignment transformation variance analysis (ART ANOVA) and generalized linear mixed model (GLMM) were introduced to improve the scientific and accuracy of repeated measurement data. All statistical calculations were carried out with R 3.6.1 statistical analysis software.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Qilong capsules (QLC), produced by Jining Huaneng Pharmaceutical Factory Co., Ltd.Drug
The recommended dosage of QLC was 0.4g each time, 3 times a day. The course of treatment was 12 weeks.
| Study group | Role | What they receive |
|---|---|---|
| Exposure group | The exposure group was the patients who were treated with Qilong capsules (QLC). The willingness of the patients and the objective judgment of the clinician were comprehensively considered to decide whether to use QLC for intervention. Patients who chose to use QLC for intervention would take it immediately after being deemed eligible for enrollment. The recommended dosage of QLC was 0.4g each time, 3 times a day. The course of treatment was 12 weeks. QLC was produced by Jining Huaneng Pharmaceutical Factory Co., Ltd. All participants in the exposure groups received the standard level of CT provided by clinicians according to the clinical diagnosis and treatment guidelines for IS, including antiplatelet aggregation drugs, antihypertensive drugs, hypoglycemic drugs, and lipid-lowering drugs.

| Non-exposure group | The non-exposure group was the patients who did not take QLC. All participants in the non-exposure groups received the standard level of CT provided by clinicians according to the clinical diagnosis and treatment guidelines for IS, including antiplatelet aggregation drugs, antihypertensive drugs, hypoglycemic drugs, and lipid-lowering drugs. |

Questions about this trial
What is this clinical trial studying?
An observational study of Ischemic Stroke, run by China Academy of Chinese Medical Sciences at 1 site in China.
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 1 inclusion and 1 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: finished, as of the sponsor's last update on 4 Apr 2022. 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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
ischemic stroke recurrence events (time frame: 1 year follow-up). The study lists 2 primary outcomes in all. 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 NCT03174535, which also lists 3 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 4 Apr 2022.
