What are the contents of the drug research phase regulations?
Drug development mainly had the following stages and relevant regulations: - ** Pre-clinical research stage **: Mainly includes the discovery and screening of new active ingredients, and the development of pharmacology and toxicity experiments (safety evaluation tests). - ** New drug clinical trial phase **: - ** Phase I clinical trial **: It is a preliminary clinical pharmacology and human safety evaluation test to observe the human body's tolerance to the new drug and its pharmacology, and to provide a basis for the formulation of the drug administration plan. The number of cases is 20 - 30. - ** Phase II clinical trial **: It is the preliminary evaluation stage of the treatment effect. The purpose is to preliminary evaluate the treatment effect and safety of the drug on patients with the target indication. It also includes providing a basis for the design of the phase III clinical trial and the determination of the dosage plan. The research design can be in various forms, such as a random blind controlled clinical trial. The number of cases should not be less than 100. - ** Phase III clinical trial **: It is the confirmation stage of the treatment effect. The purpose is to further verify the treatment effect and safety of the drug for patients with the target indication, evaluate the relationship between benefits and risks, and finally provide sufficient evidence for the review of the drug registration application. The trial should generally be a random, blind, controlled trial with sufficient sample size. According to the requirements of different diseases and dosage forms, the number of cases should not be less than 300. - ** Phase IV clinical trial **: It is the application research stage after the new drug is launched. The purpose is to investigate the efficacy and adverse reactions of the drug under widespread use conditions, evaluate the relationship between benefits and risks of using it in general or special populations, and improve the dosage. The number of cases shall not be less than 2000. - ** Bioequivalent test **: It refers to a human trial that uses the method of the study of the bio-utilization to compare the preparations of the same or different dosage forms of the same drug. Under the same test conditions, the degree and speed of absorption of the active ingredients are compared. Generally, 18 - 24 cases are involved. Generally, the development of a generic-type drug requires a bioequivalent test. - ** Production and post-marketing research phase **: The commercial production of drugs should comply with the Good Drug Production Practice, and the clinical use of drugs in the research and development phase should comply with the Good Drug clinical Trial Practice. During the R & D process, stability studies were carried out throughout the entire stage. It was necessary to follow relevant domestic and international regulations, such as ChP2020 <9001 Guidance on the stability testing of drug substances and preparations>, ChP2020 <9402 Guidance on the stability testing of biological products>, ICHQ1A-Q1E, relevant regulations of the World Health Organization, and 211.166 Stability testing of the Food and Drug Administration.

What are the contents of clinical drug research?
The contents of clinical drug research mainly include the following aspects: ** 1. Effect of the medicine ** 1. ** clinical effects ** - To determine whether the drug has a treatment effect on a specific disease, such as whether it can improve symptoms, reduce the severity of the disease, or cure the disease. This helped doctors find the best methods and drugs to improve, control, and treat diseases. 2. ** Pharmacological effects ** - To explore the pharmacology of drugs in the body, such as how the drugs interact with the body's receptor, the receptor, or other biological molecules to exert their effects. 3. ** Other functions ** - It might involve the effects of drugs on the overall physiological functions of the body, such as the immune system and metabolism. ** 2. Side effects of the drug ** - The possible adverse reactions of the study drug included mild discomfort symptoms to serious toxic reactions. This was because while the drug brought benefits to the patient, there might be some adverse reactions that had never been encountered before. The discovery of these adverse reactions was crucial for a comprehensive assessment of the safety of the drug. ** 3. Absorption, distribution, metabolism and secretion of drugs ** 1. ** Absorb ** - Understand the way drugs enter the body (such as oral administration, injection, etc.) and the speed and degree of absorption. For example, some drugs are easily dehydrated in water, and will be destroyed when they meet acid, alkalium, and oxidants, which will affect their absorption. Penicilin is generally not taken by the mouth because it is easily degraded by the presence of an enzyme. 2. ** Dispersion ** - Studying the distribution of drugs in different tissues and organs in the body would help to understand whether the drugs could reach the site of the disease. 3. ** Metabolization ** - To investigate the metabolism process of drugs in the body, including which hormones are involved in the metabolism, what the metabolism products are, and whether the metabolism products are active or toxic. 4. ** Excretion ** - To determine the way the drug and its metabolism products are discharged from the body (such as through kidney secretion, bile secretion, etc.) and the rate of secretion. ** IV. Drug effectiveness and safety ** 1. ** Validity ** - Through systematic research to confirm or discover whether the drug can achieve the expected treatment effect, such as whether it can effectively kill the pathogen and improve physiological function. 2. ** Security ** - The safety of drugs was evaluated based on the three principles of science, law, and ethics. They had to consider the risks and benefits of the drug in clinical trials to ensure that the drug would not bring unacceptable risks to the subjects while treating the disease. When intolerable adverse reactions occurred, the research team had to take emergency measures to ensure the safety of the subjects. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the content of the drug research process?
The drug research process mainly included the following contents: ** 1. Candidate Drug Development (New Drug Discovered)** 1. ** Disease confirmation, target confirmation ** - First of all, it was necessary to determine the type of disease that the drug was used to treat and understand the pathogenic mechanism of the disease. This was just like determining the combat target. For example, when developing drugs for the 2019 coronaviruses, it was necessary to understand the mechanism of the virus invading cells, replicating, and releasing in the body, and to find effective targets from the signal molecules and the binding sites of the virus. 2. ** Lead compound found ** - After determining the target, they had to find the compound that had an effect on the target. Its source could be natural products, such as natural active substances excavated from animals, plants, and marine organisms, or it could be an improvement of known drugs. This process usually used high-throughout screening, computer simulation screening, rational design, and other methods to determine which compounds had medicinal development value through cell experiments. 3. ** Lead compound optimization ** - After finding the lead compound, it was necessary to analyze the relationship between its chemical structure and its efficacy, and then optimize its structure to obtain the optimal compound that could play a more effective role, which was also the candidate drug. ** II. Preclinic research ** 1. ** chemical synthesis ** - The R & D department first designed the route to synthesize the optimal compound, and then the process department designed the drug synthesis route according to the needs, and constantly adjusted the process to obtain enough compounds to meet the needs of follow-up research and clinical trials. This was also the process of perfecting the drug preparation process. 2. ** PK ** - The absorption, distribution, metabolism, and secretion of drugs in the body were studied through animal models. These research data could guide the initial formulation of the drug administration plan, such as determining the best way to administer the drug (oral, intravenous, nasal, etc.), the frequency of administration, and the dosage adjustment for special patients (such as patients with kidney failure). 3. ** Drug Safety ** - In addition to treating the target disease, evaluate the possible effects of the drug on other parts of the body, especially on important parts such as the cardiovascular system, nervous system, and organs. 4. ** Drug toxicity research ** - Study the toxicity, cancerism, reproductive toxicity, etc. of drugs taken for a long time, and avoid including drugs with serious toxic reactions in further research plans. 5. ** Formula research, formulation development ** - Based on the conclusions of the previous studies, they would develop a new drug that could finally be used on the market. ** III. clinical trial (phase I-III)** 1. ** Phase I clinical trial ** - It mainly conducted small-scale experiments on healthy volunteers, focusing on the safety of the drug, including the absorption, distribution, metabolism, and secretion of the drug in the human body to determine the safe dosage range. 2. ** Phase II clinical trial ** - Trials were conducted on patients to evaluate the treatment effect of the drug on the target disease. At the same time, the safety of the drug was further observed to explore the appropriate dosage plan. 3. ** Phase III clinical trial ** - Trials were conducted on a larger patient population to comprehensively evaluate the effectiveness and safety of the drug, providing sufficient evidence for the approval of the drug. ** IV. New drug application, marketing approval, and post-marketing monitoring (Phase IV clinical trial)** 1. ** New drug application and approval ** - The developer submitted a new drug application to the relevant department, and the drug could be sold after review and approval. 2. ** Post-marketing monitoring (Phase IV clinical trial)** - After the drug was launched, the safety and effectiveness of the drug in a large population were continuously monitored, and information on adverse reactions was collected so that the medication guidelines could be adjusted or the drug could be improved in a timely manner. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What's the difference between medical device and drug regulations?
There were many differences between medical device and drug regulations. In terms of supervision classification, medical devices are managed in three categories according to the degree of risk. For example, Class I medical device manufacturers are subject to filing management, while Class II and Class III are subject to license management. Among operating enterprises, Class I does not require license and filing, Class II is subject to filing management, and Class III is subject to license management. Although drugs were also classified, the classification basis and management method were different from medical devices. From the perspective of license and filing management, the administrative measures for the registration and filing of medical devices (such as the administrative measures for the registration and filing of medical devices, the administrative measures for the registration and filing of in-vitro-diagnosis reagents, etc.) have their own regulations, which involve the registration and filing requirements and procedures of different types of medical devices, which are different from the regulations for the registration and filing of drugs. In terms of adverse event monitoring, medical devices have the Management Methods for Medical Device adverse event monitoring and re-evaluation, and a medical device adverse event monitoring system has been established. Pharmaceuticals have an independent adverse drug reaction monitoring system. The two are different in terms of the main body of monitoring, process, and treatment measures. In terms of the management regulations on the production, distribution and use, there were regulations specifically for the production, distribution (such as the Regulations on the Supervision and Administration of Medical Device Production and the Regulations on the Supervision and Administration of Medical Device Marketing) and use (the Regulations on the Supervision and Administration of Medical Device Use Quality) of medical devices. These regulations took into account the characteristics of medical devices and formulated corresponding rules. Pharmaceuticals also had corresponding regulations for production, distribution and use. The details and focus of the management of the two were different. In terms of advertisement review, the advertisement review management of medical devices and the advertisement review management of drugs followed their own laws and regulations respectively. Different review standards and requirements were set according to the different characteristics, risks and other factors of medical devices and drugs. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Salivary cancer effective drug research and development
The research and development of drugs for Salivary Gland Cancer had made progress in many aspects. In terms of drug therapy research based on the ESCat classification, the drug therapy for Salivary Gland Cancer was divided into four types: one was the NTrK fusion inhibition drugs Entritini and Larotinib, and the other was targeted at the over-expression of HEL2.(For example, trastuzumab-pertuzumab-pertuzumpertuzum-pertuzum-pertuzumpertuzum In terms of anti-HEL2 therapy, studies have shown that trastulizumab-plus-taxotere in the treatment of HEL-amplified saliva gland cancer has achieved an objective response rate (ORR) of 70.2%, and in the treatment of patients with HEL2 overexpressed or amplified saliva gland cancer with patotubizumab-plus-tratotubizumab-plus-taxotere, the ORR has reached 60%. In 2021, a study conducted by AscO used the ADC drug, DS - 8201, to treat patients with SADC as second-line therapy. The PR rate reached 47.1% and the DOR was 12.9 months. It was confirmed that HER-2 was a driver gene of saliva gland cancer. In a study reported at the 2024 Annual Meeting of the American Society of Clinic Oncers (Asco), pirotinib (an oral irreversible pan-Her receptor Tyrosin Kinase) was used to treat HER2 variant advanced stage Salivary Gland Cancer (SGC). The efficacy and safety of pirotinib in patients with HER2 amplification, over-expression, or mutation in advanced SGC were being evaluated. In terms of anti-androgen therapy, anti-androgen therapy for Salivary Ductal Carcinomas (SDCs) was the highest AR expression subclass in saliva glands. The study showed that leuprorelin + bicalutamide treatment for patients with Salivary Ductal Carcinomas (34 SDCs and 2 other patients) achieved a PR + PR rate of 41.7%. After 24 patients (19 SDCs) failed previous ADT, they were treated with abraterone + Prednisone + LHGH Analogy as a salvage plan. The ORR was 21% and the DPR was 62.5%. In addition, in the case of a malignant tumor of the saliva gland, the study found that the small molecular inhibition of MMD2 could reduce the number of cancer stem cells and reduce the relapse rate of mice. Although there was no FDa-approved drug for the treatment of this cancer, it provided a new direction for the treatment of saliva gland cancer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How does drug science fiction influence real - world drug research?
Drug science fiction can inspire real - world drug research in some ways. It can spark the imagination of researchers. For example, a fictional concept of a drug that can erase bad memories might lead researchers to think about ways to target and manipulate certain neural pathways related to memory. However, it also serves as a cautionary tale. The negative consequences of fictional drugs, like addiction or mind control, can make researchers more aware of the potential risks in their own work.
