Biopharma Drug Discovery is hitting right at the market spaces and seems to have a massive impact on drug development. These are broken down as following five stages and covers everything starting from complexity to approval after evaluation.
Step 1: Discovery and Development
With the first step being discovery and new insights on the treatment pathway, drugs are considered with potential efficacy and side effects.
Discovery is all about the insights researchers gain through different processes that allow them to prevent, stop, or reverse the disease. Multiple tests associated with molecular compounds against diseases to know the potential. Check and run existing treatments for unanticipated results. Genetic manipulating and targeted therapy technologies are also a way for discovering diseases.
Development is a long process in Biopharma Drug Discovery. The promising compound found in discovery is checked thoroughly with experimentation. The complete study is done for the following:
Absorption, distribution, metabolism, digestion, and excretion.
Mechanism of action and associated benefits.
Dosage and mode of drug infusion.
Compatibility with different medicines and toxicity levels.
Effectiveness with existing drugs.
The difference in effectiveness by the group of people.
Step 2: Preclinical Research
Once the discovery and development are made in Biopharma Drug Discovery, the preclinical research is carried out. Before testing drugs on people, there is potential research done with two types as ‘In Vitro’ and ‘In Vivo’.
In Vitro
In in vitro preclinical research, the cell lines are derived from humans or animals and are introduced to the drug under development. This is carried out within a petri dish or test tube based on the studies and testing conditions.
In Vivo
In vivo is the part where the research is done within an entire living being. The preclinical trials are done with utmost safety on candidates that are authorised.
These studies are carried out to know whether it is safe to consume and how the drugs work when tested.
Step 3: Clinical Development
Clinical development is the stage where researchers design the trials on the product. There are series from early, the small crowd to the large and late-stage studies with the trials. The clinical development in Biopharma Drug Discovery has the following phases as below:
Phase 1
The study has about 20 - 100 healthy volunteers with the disease or conditions of the disease. The study lasted for several months with controlled safety and dosages timely. An approximate 70% of drugs are qualified to enter Phase 2.
Phase 2
The study has hundreds of volunteers with disease and is treated, studied for about months to 2 years on minimum. The efficacy and side effects are taken into interest. About 33% of drugs are headed to Phase 3.
Phase 3
The study focuses on 300 to 3000 volunteers who have the disease and are studied for 1 - 4 years. Efficacy and reaction studies are an interest of clinical development. Drugs of 25 - 30 % approximately quality to final Phase 4.
Phase 4
Thousands of volunteers with diseases and taken for the studies. The interest in the final phase is safety and efficacy.
Step 4: FDA Review
The FDA review team, while in Biopharma Drug Discovery, the FDA review team thoroughly looks over the data on the drug and has the power to approve or disapprove the drug. The NDA (New Drug Application) has the full story that demonstrates the drug safety and efficiency with the studies.
Step 5: FDA Post-market Safety Monitoring
The safety and efficiency are known at the preclinical trials and the development phases, yet the safety cannot be predicted fully. Hence, the steps limitations bring up concerns and products safety is understood within the months or years of product at the market.
FDA in Biopharma Drug Discovery tracks and reports monitoring of drugs and gives in cautions and measures on the pack when the drugs are circulating.
