Precision medicine: computational drug repositioning for rare diseases
A study published in Drug Discovery Today shows the unmet needs in drug development for rare diseases. In this context, computational drug repositioning has been successfully applied to the development of treatments for diseases and has been shown to be a promising approach. However, the use of these novel findings from genomic data to conduct and implement computational drug repositioning approaches for rare disease therapies is still an open issue. The study focuses on how accumulated genomic data can accelerate and facilitate drug repositioning for rare diseases, and also highlights that treatments for rare diseases have received a great support from government-sponsored initiatives which helps the research and development of new therapies in the practice of precision medicine.

Characteristics of novel therapeutics and postmarket safety events
A study published in the Journal of the American Medical Association highlights three additional characteristics of novel therapeutics that should be considered when examining potential predictors of postmarket safety events after FDA approval. The following characteristics are:
- withdrawals due to safety concerns.
- FDA issuance of incremental boxed warnings added in the postmarket period.
- FDA issuance of safety communications.
The study shows that risks may only become evident when novel therapeutics are used in much larger patient populations and for longer durations in the postmarket period, which could enhance patient safety if factors of risk are found with postmarket safety events. Orphan products are represented the postmarket safety events of novel therapeutics described in this study. The study concludes that there is a need for continuous monitoring of the safety of novel therapeutics throughout their life cycle due to the high frequency of postmarket safety events.
