An Exploratory Clinical Study of Photodynamic Therapy Combined With Sonodynamic Therapy in Cholangiocarcinoma
An Exploratory Clinical Study of Photodynamic Therapy With Hematoporphyrin Injection Combined With Sonodynamic Therapy in the Treatment of Inoperable Cholangiocarcinoma
After enrollment, they received photodynamic therapy and sonodynamic therapy for a maximum of 2 times, and the longest treatment time was 6 months.The investigator will judge whether the second photodynamic therapy+ sonodynamic therapy treatment treatment is necessary according to the tolerance and tumor progress of the subject. The second photodynamic therapy+ sonodynamic therapy treatmentwill be carried out at the end of the sixth month. After the treatment period, the patients will be followed up once in the first, third and sixth months respectively, and then every three months. The observation and follow-up were carried out from the first subject after randomization to the end of 24 months after the last case.
The inspection and follow-up evaluation on the 7th day of the treatment period, including vital sign examination, blood routine examination, urine routine examination, blood biochemical examination, electrocardiogram examination, recording the number of times of plastic stent/metal stent drainage/drainage tube replacement, evaluation of physical status scale, evaluation of quality-of-life scale, recording concomitant medication and adverse events.
At the end of the first, third and sixth month, you need to come to the hospital for follow-up evaluation. In the test group, the investigator shall judge whether the second photodynamic therapy is needed at the end of the sixth month according to the tolerance and tumor progression of the subject. Before receiving the next photodynamic therapy, your body and quality of life must be evaluated according to KPS score and quality of life scale Arrange laboratory and relevant examinations. If the second photodynamic therapy is needed, continue to record the concomitant medication and adverse events at this stage.
During the follow-up period, after the longest treatment period of 6 months, a follow-up was conducted every 3 months until the end of 24 months after the last subject was enrolled in the scheme. Your survival, replacement of plastic stent/metal stent/drainage tube, biliary drainage, treatment methods for cholangiocarcinoma and serious adverse events were recorded during the follow-up.

Hematoporphyrin injection is a new drug for tumor photodynamic therapy approved by the State Food and Drug Administration of China. It is a representative drug of domestic photosensitizer with independent intellectual property rights developed and produced by Chongqing Huading Modern Biological Pharmaceutical Co., Ltd. In the third phase clinical trial, the dosage of hematoporphyrin injection (5mg/kg) should be given intravenously 48-72 hours before laser irradiation for diagnosis and treatment, and skin test should be conducted before injection. Diagnostic laser wavelength is 514.5nm, power density is 10mW/cm2, therapeutic laser wavelength is 630-690nm, average output power density is 400mW/cm, and optical dose density is 200-400J/cm2 The chemical structure formula of hematoporphyrin is: C34H38N4O6, molecular weight: 598.70 |
Hematoporphyrin in tumor tissue will be greatly enhanced by the combination of Sonodynamic Therapy and Photodynamic Therapy and achieve better treatment effect.
