1. The development and launch of drugs is not an easy task.
The time required for drug research and development is much longer than we imagined. What we see are drugs, but the drug research and development process has many difficulties and is also a very long one. The process, specifically:
1. The success rate of drug laboratory development is between 0.05-0.1%.
In other words, there are more than thousands of drug research subjects before one research subject can become a drug. It is conceivable that the drug's early experimental stage will have to experience at least thousands of failures.
2. The drug development process requires multiple clinical trials.
As far as phase III clinical trials are concerned, it is necessary to fully verify the safety, efficacy, dosage, etc. of the drug. In terms of cost, the entire process usually costs billions of dollars.
3. It takes at least 5 years for a drug to be successfully developed.
According to statistics: Between 2010 and 2020, the U.S. Food and Drug Administration (FDA) approved 440 new drugs. The time range for clinical development ranges from 5 years to more than 20 years. The average time required is 8.3 years. two. The current status of research and development of new coronavirus drugs in my country.
1. my country is at the forefront of the world in COVID-19 drug research and development.
my country is one of the first countries to invest in the research and development of COVID-19 drugs. In terms of data, patent applications and authorized invention patents for COVID-19 drugs account for 56% and 70% of the global patent volume respectively. Currently, more than 30 new coronavirus drugs are in the clinical trial stage in our country.
2. There are already two new coronavirus drugs on the market in my country.
One is the new coronavirus neutralizing antibody combination treatment drug ambavirumab injection and romisevirimab injection, which were approved for marketing in December 2021, and the other is the oral drug Azizumab Fudine tablets were approved for marketing on July 25, 2022.
Some people may ask, why did these two drugs come to the market so quickly? On the one hand, it shows the full investment of our scientific researchers, on the other hand, we took "shortcuts". As for the oral drug Azivudine tablets, it was originally a drug to treat AIDS. After the outbreak of the new coronavirus, it was screened by a large number of scientific researchers and found to be effective against the new coronavirus and was used as a drug to treat the new coronavirus. three. It’s been three years since the epidemic, why haven’t there been any effective drugs yet?
What are specific drugs? In common people’s words, it is a drug that can have an immediate effect. The COVID-19 drugs that have been developed include Monupivir, the world’s first oral drug for COVID-19, Paxlovid developed by Pfizer, and Azivudine, an oral drug marketed in my country. Although tablets were called special medicines when they were launched on the market, they are not what ordinary people call "special medicines". Why? Because the new coronavirus is still mutating.
The constantly mutating new coronavirus has not only made it more difficult for us to fight the epidemic, it has also had a certain impact on the effectiveness of the new coronavirus vaccine and new coronavirus drugs. Therefore, the launch of new coronavirus specific drugs is not a short-term matter. , we should fully understand this.
