Time was passing slowly. There is rarely a chance. A little girl, stricken with a rare genetic disorder, had undergone every possible treatment. A new gene-editing therapy that had recently come out of clinical trials gave her doctors some hope. Meanwhile, the physicians opted for this treatment. A couple of months later, her disease had reached a much-improved state, showcasing the boundless power of modern medicine.
One such story of this medical miracle is of Victoria Gray, one of the first people to use the CRISPR gene-editing technique to successfully treat sickle cell anaemia. Post-treatment, the patient was freed from the debilitating pain crisis that once suffused her life, thus highlighting the power of modern pharmacological advancements.
Research advancements being undertaken in top pharmaceutical science colleges in Maharashtra, evolving technology and changing patient expectations are driving changes in drug discovery and development. Academic institutions and research organisations are vital in educating the next generation of pharmaceutical innovators to build on these advances.
The need for faster, safer, and more effective therapies has been growing in line with the expanding requirements of the global market, which is pushing scientists and pharmaceutical companies to look into new ideas.
The Evolution of Drug Development: A Shift Towards Innovation
Bringing a new drug to market is a complicated, costly process that can take a decade or more and consume billions of dollars. Previously drug discovery followed a trial-and-error base, but through computer modelling, artificial intelligence research, and high-throughput screening, the process has changed completely.
The distribution, testing and discovery of pharmaceuticals is speeding up thanks to personalised medicine, artificial intelligence (AI) and gene editing, which is making the drugs more efficient and more accessible. A medicine that tailors therapy based on a person lifestyle, environment, and genetics — has taken the business world by storm over the last several years. This approach mitigates side effects and augments therapeutic effectiveness.
Emerging Innovations in Drug Development
- Artificial Intelligence (AI) & Machine Learning (ML) in Drug Discovery
The use of big data analytics is also revolutionising pharmaceutical research with artificial intelligence and machine learning. This allows for the prediction of the interaction between molecules, the discovery of new, potentially useful drugs, and the improved targeting of drugs. Instead of sifting through hundreds of molecules over the span of years, AI algorithms can scour data and find promising candidates for new treatments in days.
Here are some of the most notable applications of artificial intelligence in pharmaceutical research:
- Predicting Drug-Target Interactions: AI can be used to analyse molecular structures to predict how drugs will interact with biological targets.
- Drug Repositioning: AI algorithms can find new therapeutic indications for existing drugs, thereby shortening the time to develop new drugs.
- Clinical Trial Optimisation: AI assists in identifying optimal patient populations, forecasting trial success, and reducing risk.
Companies like DeepMind, Benevolent AI, In-silico Medicine are using AI to accelerate drug discovery. Here we explain how AI-enabled algorithms have dramatically shortened the time required for identifying leads, allowing for drug companies to deliver cutting-edge medicines faster.
- CRISPR and Gene Editing
In particular, the CRISPR-Cas9 is greatly revolutionising the treatment of hereditary diseases using gene-editing technologies. Small but critical changes in their DNA sequences allow scientists to correct the glitches that cause sickle cell anaemia and cystic fibrosis. This provides new hope for the suffering all around.
Gene editing has various medical applications, including:
- Eradicating genetic illnesses: CRISPR could also solve hereditary diseases at the gene level.
- Targeting cancer mutations: Scientists are employing CRISPR to change immune cells so they can better pursue and destroy cancer cells.
- Developing personalised gene therapies: Treatments that have been customised according to an individual’s genetic background deliver superior results.
Despite still being in its infancy, gene-editing technology represents a tremendous hope for the future of medicine.
- Expanding mRNA Technology Beyond Vaccines
It has also led to new applications of mRNA technology in the treatment of rare genetic diseases, cancers and infectious diseases following the development of mRNA-based COVID-19 vaccines. Scientists are developing personalised vaccinations for cancer that are more efficacious against tumours and induce fewer side-effects.
Some of the key benefits of mRNA-based therapies are:
- Shorter development timelines than conventional vaccines and medications.
- More room for narrowing down on specific diseases with customised mRNA sequences.
- Avoids the risk of contamination since mRNA production does not involve using live viruses or cells.
- 3D Printing in Pharmaceuticals
3D printing techniques are changing the pharmaceutical formulation making it more personalised with respect to dose, release patterns and even drug combinations ultimately leading to improved therapeutic outcomes and patient compliance.
Key applications include:
- Personalised medication: 3D printing has enabled administering medications that can be customised to a patient’s metabolism and condition.
- Advanced drug formulations: Allows for the production of multilayer dosage forms with distinct release characteristics.
- On-demand drug production: Hospitals and pharmacies could potentially print out medications on premises, alleviating reliance on supply chains.
The first 3D-printed epilepsy drug to receive FDA approval, for example, is Spritam, which dissolves quickly for patients with trouble swallowing.
Advances in Drug Formulation
- Targeted Drug Delivery Using Nanotechnology: Recent innovations in nanotechnology have improved drug solubility, targeted drug delivery and stability. Liposomal formulation and nanoparticle-based drug delivery systems not only intensify the therapeutic effects of drugs used in cancer therapy but also significantly reduce their associated toxicity and adverse effects. Nanocarriers help medications reach sick tissues while preserving healthy cells and minimising side effects.
- Long-Acting Injectables (LAIs) Long-acting injectables (LAIs) can help manage diseases like HIV and schizophrenia by minimising the need for regular dosage, thus improving adherence and treatment success. Such formulations permit the treatment to be given multiple times over weeks or months.
- Smart Drug Delivery Systems Responsive drug delivery systems released drug only in response to some physiological signals such as pH, temperature and enzyme activities. These advances are the very best thing that could happen for the management of chronic illness like cancer and diabetes.
- Biodegradable Implants and Patches Transdermal patches and innovative biodegradable implants ensure the prolonged pharmaceutical delivery of pharmaceutical substances which is required. For example, the implementation of opiate addiction implants time-released a constant stream of medication for months, eliminating the need to come in regularly for a dosage.
The Role of Education in Embracing These Innovations
Educational institutions must explore these new technologies to build future pharmacists who are well-prepared to meet the needs of the modern world in an era when pharmaceutical sciences are changing and advancing rapidly. Some of the main areas to focus on are:
- Techniques for drug discovery using artificial intelligence
- Gene-editing techniques such as CRISPR
- Nanotechnology and personalised medicine application and the key applications of 3D printing in pharmaceutical formulation.
