[Clinical trials] This product was approved for clinical research by the State Drug Administration in March 2003, and Phase I, II, and III clinical trials were conducted from September 2003 to February 2005.
The phase Ⅰ clinical trial was to observe the tolerance of the human body to salvia polyphenolic acid for injection and to determine the safe range of clinical administration. There are five dose groups in the single-stage tolerability test of Phase I, which are administered with 0.5, 1, 2.25, 3, and 4 drugs, respectively, for a total of 28 people; the continuous dose tolerance test is divided into 1 and Two groups of two doses, a total of 12 people, once a day, continuous administration for 14 days. The single-dose and continuous-dose tolerance test methods are: intravenous injection of danshen polyphenolic acid and 0.9% sodium chloride injection 250ml, the drip rate is 30-40 drops / minute. The results of the phase Ⅰ clinical trial recommended that the proposed clinical dosage of this product is 1-2 per time / day.
Phase Ⅱ and Ⅲ clinical trials are to observe the effectiveness and safety of stasis and blood clotting syndrome in the recovery period of stroke disease (mild to moderate atherosclerotic thrombotic cerebral infarction) for salvia polyphenolic acid for injection. The design of clinical trials were multi-center, randomized, blinded, double-dose, and positive control. The control drug was Xuesaitong for injection. Method of administration: Test group (low-dose group): one salvia polyphenolic acid for injection, diluted with 0.9% sodium chloride injection, and then intravenously, once a day. Test group (high-dose group): 2 injections of salvia polyphenolic acid for injection, diluted with 0.9% sodium chloride injection, intravenously, once a day. Control group: 200mg Xuesaitong for injection, diluted with 0.9% sodium chloride injection, and then intravenously, once a day. During the medication, the drip rate is strictly controlled, and it is required to be no higher than 40 drops / min. The course of treatment is 14 days.
There were 234 cases of Phase II clinical observations, including 78 cases of Xuesaitong for injection, 77 cases of low-dose polyphenolic acid (1) group for injection, and 79 cases of high-dose polyphenolic acid (2) group for injection; The number of clinical observation cases in stage Ⅲ was 521 cases, of which 173 were Xuesaitong for injection, 173 were in low-dose (1) salvia polyphenolic acid group, and 175 were in high-dose (2) salvia polyphenolic acid injection group. . The cases included in phase Ⅱ and phase Ⅲ clinical trials were mainly patients with blood stasis and obstruction due to stroke recovery during the meridian recovery period. Western medicine diagnosed patients with mild to moderate atherosclerotic thrombotic cerebral infarction. Age 30-70 years. The analysis of the main factors influencing the evaluation of the efficacy of the experimental group and the control group before treatment suggested comparability.
Results of Phase Ⅱ clinical trials: In terms of the comprehensive efficacy of stroke, the total efficacy of the low-dose salvianolate group was better than that of Xuesaitong group, the low-dose salvia polyphenolate group and the high-dose salvia polyphenolic group, and There was no significant difference between the high-dose group and the Xuesaitong group. There was no significant difference in the efficacy and total effective rate of TCM syndromes in each group. There was no statistically significant difference in the efficacy of neurological deficit score improvement in each group. Analysis of the efficacy of related symptoms and signs showed no difference between the groups.
Results of phase Ⅲ clinical trials: In terms of comprehensive efficacy of stroke, the high-dose salvia polyphenolic acid group and the low-dose salvia polyphenolic acid group were better than the Xuesaitong group. In terms of the efficacy of TCM syndromes, the high-dose salvia polyphenolic acid group was superior to the Xuesaitong group, and the differences between the other groups were not statistically significant. The clinical neurological deficit score scores improved curative effect: Danshen polyphenolic acid high dose group and Danshen polyphenolic acid low dose group were better than Xuesaitong group.
In terms of the individual symptom recovery rate of TCM syndromes, the scores of TCM syndromes in the three groups during the treatment showed that the high-dose salvia polyphenolic acid group and the low-dose salvia polyphenolic acid group could significantly improve the hemiplegia caused by stroke. The symptoms of skewed tongue, astringent or silent speech, headache, limb pain, numbness, irritability and irritability were statistically analyzed. The test group was better than the control group.
Compared with the high-dose salvia polyphenolic acid group and the low-dose salvia polyphenolic acid, the clinical cure rate, marked recovery rate and total effective rate were not statistically significant. Only a few high-dose groups were better than low-dose groups.
In terms of safety: During the clinical trial, 40 patients in the phase I clinical trials had undergone relevant safety checks before and after treatment, and the number of cases in the treatment group before and after treatment in the phase II and III clinical trials: blood routine 498 There were 496 cases of routine urine, 459 cases of routine urine, 459 cases of liver function (ALT497, AST496 cases), renal function (BUN498 cases, Cr498 cases), myocardial enzymes (CK482 cases, CK-MB477 cases) and electrocardiogram 496 cases. Most of the treatments were normal before and after treatment, and some patients had abnormalities after normal treatment before treatment and abnormalities before treatment. Most of the abnormalities worsened after treatment. Most of the abnormalities or changes were minor, and most were considered to have no clinical significance and had nothing to do with the test drug. However, a small number of changes are more obvious, which may be related to the test drug.
In the single-stage tolerant administration in the first-stage clinical trial, 3 cases of high-dose group (4 sticks / day / person) had dizziness symptoms after treatment, and no other complaints were reported. The symptoms lasted for about 20 minutes, and the dizziness symptoms resolved on their own. The investigator determined that the relationship with the test drug was suspicious; in the low-dose group (0.5 sticks / day / person), one patient had a myocardial enzyme CK elevation of 648 U / L and a CK-MB elevation of 26 U / L 24 hours after administration, and a review was performed after 1 day CK was 1549U / L, CK-MB was 40U / L, and after 7 days, CK was 261U / L, and CK-MB was 25U / L. The researchers thought that it may be related to cold after exercise and has nothing to do with the test drug. The patient experienced a slight decrease in diastolic blood pressure, which was not ruled out as related to the drug. In the continuous-dose small-dose group (1 stick / day / person), 4 subjects felt mild head and eye fullness after taking the drug, which the researchers thought may be related to the drug.
Phase Ⅱ clinical trial: 1 patient in the low-dose salvia polyphenolic acid group (1 stick / day) had a blood pressure of 150 / 100mmHg and numbness in the lips after 1 day of administration, and the blood pressure did not decrease after using antihypertensive drugs. 110mmHg, drug withdrawal, blood pressure returned to normal, it is not ruled out that it is related to the test drug. One case of the salvia polyphenolic acid high-dose (2 sticks / day) group for 7 days after the administration showed a large amount of erythema, pimples, pruritus, and pruritus on the face and behind the ear. It disappeared for several hours without treatment. The patient had eaten shrimp and crab the night before, and the researchers did not rule out that it had nothing to do with the test drug.
In the low-dose group, ALT and AST increased from 30U / L and 30U / L before treatment to 127U / L and 86U / L after treatment, and 1 case increased from 48U / L and 38U / L before treatment. After treatment, 78U / L and 45U / L are considered to be related to the test drug. Phase Ⅲ clinical trial, high-dose salvia polyphenolic acid injection group (2 sticks / day), 1 case was treated on the 3rd day, 40 minutes after infusion, skin flushing, sweating, mild symptoms, slower drip rate, no After stopping the drug, the symptoms disappeared after 30 minutes, and similar symptoms did not appear after continued administration. The researchers determined that it may be related to the test drug; high dose (2 sticks / day), 1 case after the drug was administered for 1 day, conscious body fever, but the body temperature was normal (36.8 ° C), no facial flushing, no skin rash, no cough and other symptoms, disappeared after 1 hour, and withdrew from the test. The researchers thought it might be related to the test drug. One patient received a low dose (1 stick / day). On the third day of medication, he experienced headache and eye swelling for 2 hours, which resolved on his own. Similar symptoms did not appear after continued administration.
In the high-dose group, 2 cases of CK and CK-MB increased slightly after treatment, and 1 case of CK and CK-MB increased from 144.95 U / L, 28.8 U / L to 284.9 U / L, and 34.35 U before treatment, respectively. / L, 1 case of CK, CK-MB increased from 153U / L, 5U / L before treatment to 560U / L, 31U / L, and returned to 53U / L, 13U / L after review, which is considered to be possible with the test drug Related; 1 case in the high-dose group increased CK-MB from the original 17U / L to 43U / L after treatment, and was rechecked to 20U / L after 1 week, which was considered to be related to the drug; 1 case in the low-dose group was ALT, AST Increased from 36.8U / L and 37.2U / L before treatment to 79.1U / L and 81U / L after treatment, respectively, and the post-treatment review was 37.6U / L and 39.2U / L, which were considered to be related to the test drug. ALT and AST in the high-dose group increased from 38.9 U / L and 37.3 U / L before treatment to 103 U / L and 85 U / L after treatment, respectively, and the post-treatment review was 32.7 U / L and 30.6 U / L, respectively. L, think it may be related to the test drug.
