DRUG REPURPOSING / ORPHAN DRUG

Drug repurposing, also known as drug repositioning, is the strategic approach of identifying new therapeutic uses for existing or previously unsuccessful drugs. Meanwhile, orphan drugs are pharmaceutical compounds designed specifically to treat rare diseases. Both strategies present innovative solutions to bridge critical gaps in healthcare by accelerating treatment availability in a cost-effective manner.

Core Characteristics

Drug Repurposing:

• Leverages established pharmacological properties and well-documented safety profiles.
• Often circumvents the early, time-consuming stages of drug development.
• Includes the potential revival of drugs previously withdrawn or discontinued for their original intended use.

Orphan Drugs:

• Primarily address rare, often genetic or life-threatening diseases with limited treatment options.
• Benefit from regulatory incentives such as tax credits, expedited approval pathways, and extended market exclusivity.
• Despite a restricted commercial market, they fulfill a high unmet medical need, making them vital in rare disease therapeutics.

 

Key Applications and Advantages

Applications:

• Treatment of rare, neglected, or drug-resistant conditions.
• Used extensively in fields such as oncology, neurology, infectious diseases, and autoimmune disorders.
• Provide swift therapeutic responses to emerging global health crises, including outbreaks like COVID-19.

 

Advantages:

• Significantly reduces drug development time and associated costs.
• Minimizes the risk of clinical failure due to existing safety and efficacy data.
• Regulatory bodies such as the FDA and EMA facilitate streamlined approval processes.
• Addresses critical therapeutic deficiencies where conventional treatment strategies have been insufficient.

 

Future Outlook

• The integration of AI and bioinformatics is revolutionizing drug repurposing by enhancing predictive modelling and compound screening.
• Expansion of rare disease registries and genomic databases is fostering better patient stratification and treatment personalization.
• Increasing collaboration among academia, biotech firms, and regulatory authorities is driving innovation and improving accessibility to repurposed drugs.
• Advances in personalized medicine and precision therapeutics are expected to synergize with repurposing efforts, enabling more tailored treatment strategies.

 

Conclusion

Drug repurposing and orphan drug development represent forward-thinking, resource-efficient solutions to persistent medical challenges. By repurposing known compounds and prioritizing underserved conditions, these strategies not only accelerate the delivery of life-saving therapies but also mitigate financial and scientific risks. Their continued evolution, supported by emerging technologies and strategic partnerships, will be instrumental in shaping the next era of precision and equitable healthcare.
