Much uncertainty remains
It should be noted that fenugreek is not currently a patented drug.
According to industry analysts, 10uM (micromol/L) of fenugreek can inhibit the replication of coronavirus by 15,393 times. This data is only the result of in vitro experiments, and the results of in vitro experiments are still a long way from the birth of a new drug. distance.
A person in charge of an anti-viral company said that "Shenjintiansu" can only be called a compound under research at present, and animal experiments, including pharmacology, toxicology, drug metabolism and other preclinical studies, are required to complete the drug, and then I, II, Phase III clinical trials.
Meng Lilian, chief expert of Sichuan Tianfu Health Industry Research Institute, said in an interview with the media that the development of new drugs is a process of overcoming five obstacles.
According to the drug development process, this invention is still far from a new drug, and it is still unknown whether it can become a drug.
In the end, it still needs to pass the test of safety, animal testing, clinical trials and other links.
In general, all drugs that have not been approved for marketing in the preclinical or clinical laboratory stage cannot be called new drugs, but should be called drug candidates or drug candidates.
Therefore, at present, whether fenugreek can eventually become an anti-new crown drug, it also needs to go through animal tests, human clinical trials, marketing approval and other links, and there is great uncertainty whether it can pass.
In addition, it is reported that a Canadian pharmaceutical company has already approached the US FDA to conduct a clinical trial study on the treatment of new coronary pneumonia with fenugreek, and the clinical trial is expected to be officially launched in the second half of this year.
Soochow Securities pointed out that under the management and control policy of dynamic clearing, the new crown special medicine is the key to long-term prevention and control in the future.
At present, only Pfizer’s Paxlovid has been approved for listing with conditions in China, and no domestic Covid-19 medicine has been approved for marketing.
According to estimates, the cost of fenugreek is far lower than that of other drugs.
At present, the market price of Pfizer's Paxlovid is 2,300 yuan per box, and the real biological Azdof is estimated to be 900 yuan per course of treatment, while the price of the old drug, with reference to the old drug, is about 100 yuan per box.
