About this study

Official title: Phase Ib Clinical Study to Evaluate Safety, Tolerance,Pharmacokinetics and Efficacy of SY-007 After Intravenous Injection in Acute Ischemic Stroke Subjects

This Phase 1b multiple center, randomized, double-blind, placebo-controlled study is a dose escalation trial evaluating the safety, tolerability, PK characteristics and efficacy of SY-007 after injection in acute ischemicstroke patients. The immunogenicity of SY-007 will be evaluated and this study will provide the recommended dosage for subsequent clinical trials.

Being tested
SY-007/ Placebo 15mg, SY-007/ Placebo 30mg, SY-007/ Placebo 60mg
Medical subject headings
Ischemic Stroke

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety and tolerance of SY-007

    Number of patients with treatment-emergent adverse events and number of patients who died over 90 days

    Measured: From Day 0 to Day 90

Secondary outcomes (13)
  1. Pharmacokinetics of SY-007

    Peak Plasma Concentration (Cmax)

    Measured: From Day 0 to Day 7

  2. Pharmacokinetics of SY-007

    Area under the plasma concentration versus time curve (AUC)

    Measured: From Day 0 to Day 7

  3. Pharmacokinetics of SY-007

    Time to Cmax (Tmax)

    Measured: From Day 0 to Day 7

  4. Pharmacokinetics of SY-007

    Terminal half life (T½)

    Measured: From Day 0 to Day 7

  5. Pharmacokinetics of SY-007

    Clearance (CL)

    Measured: From Day 0 to Day 7

  6. Pharmacokinetics of SY-007

    Volume of distribution

    Measured: From Day 0 to Day 7

  7. Percentage of Participants With Excellent Outcome in Modified Rankin Scale(mRS) Score at Day 8, Day30, Day60, Day90

    Excellent mRS is defined as mRS score of 0 or 1

    Measured: Day 8, Day30, Day60, Day90

  8. Modified Rankin Scale Score at Day 8, Day30, Day60, Day90

    Modified Rankin Scale Score range from 0 to 5,higher score mean a worse outcome.

    Measured: Day 8, Day30, Day60, Day90

  9. Percentage of Participants With National Institute of Health Stroke Scale (NIHSS) range from 0 to 1 at Day 8, Day30

    Measured: Day 8, Day30

  10. Change From Baseline in NIHSS Score at Day 8, Day30 range from 0 to 1 at Day 8, Day30

    Measured: Day 8, Day30

  11. Percentage of Participants With Excellent Outcome in Barthel index (BI) Score at Day 8, Day30, Day60, Day 90

    Excellent BI outcome is defined as a score of >=95. BI consists of 10 items that measure a participant's daily functioning, specifically the activities of daily living and mobility.

    Measured: Day 8, Day30, Day60, Day 90

  12. Change of Cerebral infarction volume before and after treatment

    Measured: Baseline, Day 8, Day30

  13. Immunogenicity of SY-007

    Anti-Drug antibody evaluation

    Measured: From Day 0 to Day 30

Questions about this trial

What is this clinical trial studying?

A Phase 1 study of Acute Ischemic Stroke, run by Suzhou Yabao Pharmaceutical R&D Co., Ltd. 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 6 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: paused, as of the sponsor's last update on 27 Jun 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Safety and tolerance of SY-007 (time frame: From Day 0 to Day 90). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 27 Jun 2022.
