What Drugs Are Being Repurposed for Alzheimer's Treatment?

Alzheimer's disease poses significant challenges due to its complex pathophysiology and the lack of effective treatments. Recent studies have explored repurposing existing drugs to find new therapeutic options. 

Algernon Pharmaceuticals is investigating Dextromethorphan, a common cough suppressant, for its potential effects on neuroinflammation and cognitive function.

Similarly, Novartis AG has been evaluating existing compounds that target amyloid plaques and tau proteins, key players in Alzheimer's progression.

The concept of drug repurposing allows researchers to leverage the safety profiles of these medications while potentially providing new benefits for Alzheimer’s patients​.

What Are the Advantages of Repurposing Drugs for Cancer Treatment?

Drug repurposing offers several advantages in oncology, including cost-effectiveness and accelerated development timelines. 

Biovista has focused on creating proprietary algorithms to identify existing drugs that may be effective against various cancer types. By analyzing molecular signatures and drug interactions, Biovista can expedite the discovery process, saving valuable time compared to traditional drug development methods.

Moreover, Teva Pharmaceutical Industries has successfully repurposed Erlotinib, initially developed for lung cancer, to treat head and neck cancers, showcasing the broad applicability of repurposed therapies in oncology​.

What New Drugs Are Being Repurposed for COVID-19 Treatment?

The urgency of the COVID-19 pandemic has propelled significant advancements in drug repurposing. Companies like Lantern Pharma, Inc. and ChemBio Discovery, Inc. are actively screening existing medications for efficacy against SARS-CoV-2.

For example, Lantern Pharma has focused on leveraging its proprietary AI-driven platform to identify and validate repurposed drugs that can inhibit viral replication. The accelerated approval pathways during the pandemic have also paved the way for quicker clinical trials, facilitating the repurposing of drugs like Baricitinib for COVID-19 treatment, which was initially used for rheumatoid arthritis​.

What Challenges Do Researchers Face in Drug Repurposing?

Despite its promise, drug repurposing is not without challenges. Excelra and Fios Genomics have identified several barriers, including regulatory hurdles and the need for extensive clinical validation of repurposed drugs.

These organizations emphasize the importance of robust data analytics to ensure that repurposed drugs are effective for new indications.

Additionally, Paradigm Biopharmaceuticals Ltd is actively working to address issues related to market access and reimbursement for repurposed drugs, which can hinder their availability to patients​.

Innovations in Drug Repurposing

The field of drug repurposing is continuously evolving, with several key players leading the charge. Chord Therapeutics SA utilizes high-throughput screening techniques to identify new uses for existing drugs, significantly speeding up the discovery process. 

Predictive Oncology focuses on developing sophisticated models to predict drug efficacy based on genomic data, enhancing the chances of successful repurposing.

Meanwhile, Sosei Group Corporation is investing in advanced computational tools to streamline drug discovery and repositioning efforts, demonstrating the transformative potential of technology in this area​.
