Phase I Clinical Study to Evaluate Safety, Tolerance and Pharmacokinetics of SY-007 After Single-dose Incremental Intravenous Injection in Healthy Subjects

2019-10-07 08:56:47 | BioPortfolio


This study is a single-dose incremental, randomized, double-blind, parallel, placebo-controlled study on safety, tolerance and pharmacokinetics healthy subjects.


Six dose-group trials are planned: 1 mg,4 mg,10 mg,20 mg,30 mg,and 45 mg.When the dose reaches 45mg, if the standard of increasing dose termination is still not reached, the researcher and the sponsor shall decide whether to continue the increasing dose after reviewing the previous study data, and each increasing dose shall not exceed 33.3% (e.g., 60mg) of the previous dose group. In the process of dose increasing, when the dose exceeds 20 mg, if the dose level reaches the dose termination standard, an intermediate dose is set between this dose and the previous dose, and the study is returned to the intermediate dose group.In this study, a parallel design was adopted, in which each subject received only one dose of drug from one dose group, which ensured the safety of the subject to the greatest extent, and also avoided the interference of safety and PK results caused by possible insufficient elution or other factors.Among them, 1 mg dose group was the starting dose group, and 6 subjects were randomly assigned into sy-007 group for injection or placebo group at a ratio of 2:1. Only 2 subjects were given the drug for the first time. One day after the first two subjects were given the drug, after ensuring the safety of the first two subjects, the drug was given to the remaining 4 subjects.In other dose groups, sentry administration was also used. The first 2 subjects received sy-007 injection or placebo respectively. After 3 days of hospitalization observation, the safety data of the first 2 cases were reviewed by the researcher and the sponsor, and the remaining subjects in this dose group were determined accordingly.Pharmacokinetic biological samples were collected from all dose groups and their safety was assessed.A total of 66~90 healthy subjects will be enrolled.

Medical and Biotech [MESH] Definitions

Bleeding into one or both CEREBRAL HEMISPHERES including the BASAL GANGLIA and the CEREBRAL CORTEX. It is often associated with HYPERTENSION and CRANIOCEREBRAL TRAUMA.

A heterogeneous group of sporadic or familial disorders characterized by AMYLOID deposits in the walls of small and medium sized blood vessels of CEREBRAL CORTEX and MENINGES. Clinical features include multiple, small lobar CEREBRAL HEMORRHAGE; cerebral ischemia (BRAIN ISCHEMIA); and CEREBRAL INFARCTION. Cerebral amyloid angiopathy is unrelated to generalized AMYLOIDOSIS. Amyloidogenic peptides in this condition are nearly always the same ones found in ALZHEIMER DISEASE. (from Kumar: Robbins and Cotran: Pathologic Basis of Disease, 7th ed., 2005)

Pathological conditions of intracranial ARTERIES supplying the CEREBRUM. These diseases often are due to abnormalities or pathological processes in the ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; and POSTERIOR CEREBRAL ARTERY.

Radiography of the ventricular system of the brain after injection of air or other contrast medium directly into the cerebral ventricles. It is used also for x-ray computed tomography of the cerebral ventricles.

The largest of the cerebral arteries. It trifurcates into temporal, frontal, and parietal branches supplying blood to most of the parenchyma of these lobes in the CEREBRAL CORTEX. These are the areas involved in motor, sensory, and speech activities.
