The Overall Progress in Biopharmaceutical Development
With new technology beaming the market, biopharmaceuticals revamped their drug production and distribution techniques to several degrees, offering a smoother path through the CMC pharmaceutical evaluation process. Some of the progresses throughout the century include:
Biobetters
As you can already tell by the name, these drugs are altered for enhancing their performance. So needless to say they are chemically or functionally modified for developing them into a more “better” version.
The original version of the drugs can sometimes arrive with unsolicited side effects that can be detrimental to human life. This is because even after thorough investigation during drug development, the actual performance cannot be predicted unless it’s sent over for public usage. Hence with the help of special regulators, those drugs are refined to make biobetters.
Other than removing the unwarranted adverse effects, biobetters are also improved for achieving better clinical performance. Proteins are purposefully changed for getting a more smoother targeting and delivery. As a result, the proteins are perfected for treating targets better as well as growing less resistant.
Moreover, biobetters have more possibility of earning patents. So they have significantly improved the biopharmaceutical industry be it in terms of drug effectiveness and safety.
Roche’s Avastin antibody which is often applied in the treatment of colon cancer. However, a small fragment of it called Roche’s Lucentis can be now used for remediating age-related macular degeneration. Again, the first ever biobetter produced with an altered amino acid sequence was the insulin analog Lispro.
Transgenic Animals
Even though a lot of ethical concerns may arise for animal welfare, transgenic animals have been a gamechanger in the production of biopharmaceuticals. As a result, the overall quality and production limit is significantly benefited.
Since these drugs are produced from animals, it is also addressed with “pharming”. So in pharming, a desired protein is transferred into an animal for mass production of that particular protein with the assistance of genetic engineering. Moreover, animals have the ability to reproduce which is totally natural.
Now you’ll be shocked knowing how these proteins are collected – these proteins are actually delivered with its milk production! Goats and cows are mainly used for this purpose. However, a notable amount of these proteins are achieved from swine blood that acts as a substitute for human hemoglobin.
Transgenic animals are made by injecting a DNA protein gene coupled with mammary directing signal into a fertilized embryo which is then implanted into surrogate mothers to give birth to these wonderful animals.
ATryn, an anticoagulant, is renowned to be the first biopharmaceutical to be produced in a transgenic goat. After that, it has proceeded to develop the transgenic “super mice” to produce a human drug called tPA for treating blood clots.
Gene Therapy
Genes are considered the biological blueprints of our body and hence any errors in these genes can be corrected by harnessing gene therapy. It works by altering the genes of the patient for therapeutic purposes. Usually gene therapy is conducted by either adding a new gene or fixing a gene by inserting a good version of the faulty gene.
The vehicle for transferring the gene into the human body is called a vector. In ex-vivo, the faulty genes are collected from a person where the vector is inserted to correct the genes outside the body. But during in vivo, the vector is directly injected into the patient for target correction.
But more advanced treatments emerged with the development of CRISPR-Cas9. They are the “biological scissors” to customize a defective gene. This tool can add, remove, or simply repair the faculty gene responsible for causing diseases.
Thanks to this therapy patients are blessed with new possibilities for defeating fatal inherited disorders that may lead to disability or even early death. Moreover, earlier treatments can save further damages from causing.
Leber congenital amaurosis is a rare eye condition that can be cured by this miraculous therapy. Other extreme disorders like cystic fibrosis can also be overcome.
Precision Medicines
Just like readily available clothes, the one-size fit all policy of traditional medicines often misses the mark. It’s because our genes are further from each other. Hence personalized medications are revolutionary as they’re tailored to a patient’s unique biological getup.
A particular medicine can show life-altering consequences in one person while the same medicine can cost it their own life. That’s why taking treatments based on one’s uniqueness can be extremely effective – can be easily achieved by making customized precision medications.
By paying attention to the skeleton of DNA, personalized medicines can help people achieve a more seamless diagnosis. Moreover, they aid in predicting any upcoming disease based on symptoms as well as obstruct them from developing any further.
This showcases remarkable success in dealing with extreme disorders like cancer. So these medicines either target particular cancer cells directly or trigger the immune system to launch an attack on those cancer cells. They also eliminate any signs of side effects that may surface from consuming regular medications available for all.
Precision medicines are widely used for treating numerous types of cancers – ranging from most common like breast cancer and leukemia to the more scarce ones like melanoma and lung cancer.
Vaccine Development
Now vaccines singlehandedly remediated the world with their magical potions during the COVID-19. They’re usually a mixture of harmless bits and pieces of weakened viral toxins that are injected into the body for the treatment. This reinforces our immune system to assist in fighting off foreign microbes.
However, the entire process of developing a powerful emulsion can get pretty lengthy. That’s because religious monitoring is required during every step for precisely producing an effective vaccine. Firstly during pre-clinical trials these are tested on animals and slowly they’re applied to actual humans for further monitoring.
These advancements evolved into messenger RNA vaccine formulation. When injected, mRNA instructs the body cells to make viral protein. So the generation of antibodies is boosted as a part of the body’s coping machinery. The antibodies also stay inside for a prolonged period for fighting off any emerging entities.
Now mRNA vaccines are widely used for taming coronavirus. Pfizer and Moderna vaccines are some of the examples that became our saviors during the COVID-19 pandemic. They safeguard us by instructing our immune system to accumulate loads of antibodies.
Bioprinting
Finally bioprinting is an absolute miracle where you can 3D print but with cells! Just like 3D printers form objects going by layers, bioprinting also enables us to build organs by printing with cells instead of ink.
But patients are required to undergo an MRI scan to get a copy of their internal whereabouts. This creates a blueprint based on which the tissue model will be developed.
Firstly in Jetting-based bioprinting, human cells are mixed with bioinks to create an emulsion for printing the 3D organ. Next Extrusion-based bioprinting fabricates 2D or 3D organs by using a threadlike material consisting of cells. Finally, Integrated bioprinting uses hydrogels and aggregates consisting of cells to replicate tissue-like structures.
As a result, these models are mainly applied in research purposes for reforming the medication and cosmetic sectors. Drugs are perfect to be tested in these models that also cuts down on the overall development cost. Moreover, heart and other organ surgeries can be practiced with these dummies.
So 3D printing can construct new tissues and organs for transplantation and even plastic surgeries aside from research purposes.
Bottom Line
Biopharmaceuticals relentlessly keep on evolving with their cutting-edge research facilities for making human lives a lot more secure. So with the assistance of novel therapeutics, countless cost-efficient and resilient remedies are circulating in almost every healthcare center. Therefore, you’ll be familiar with the ongoing progress in biopharmaceutical development if you’ve made till this far!
This means biopharmaceuticals are constantly beating their own game. This industry came up with biobetters for enhancing pre-existing drugs. Transgenic animals create human protein within their milk. A faulty gene can be fixed using gene therapy and vaccine development protects us from emerging diseases. Precision medicines are tailored according to our internal conditions. Finally, cell models of 3D structures are created using bioprinting.
Therefore, the overall progress in biopharmaceutical development single handedly saved millions of civilians.
