AI Identifies Potential ALS Treatments by Repurposing Existing Drugs

Researchers are leveraging artificial intelligence (AI) to identify existing drugs that could potentially slow the progression of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease. This innovative approach, spearheaded by a team from Lawrence Livermore National Laboratory (LLNL), Stanford University, and UCLA, analyzes electronic health records to find medications originally prescribed for other conditions that may offer therapeutic benefits for ALS patients.

Repurposing Drugs: A Faster Route to ALS Treatment

Customary clinical trials for new drugs can span five to seven years, making the repurposing of existing drugs a significantly faster alternative for delivering treatments to patients in need. AI and machine learning (ML) accelerate this process by analyzing long-term electronic health records (EHRs) of ALS patients. This analysis helps identify drugs,or combinations thereof,prescribed for other conditions that may influence the disease’s progression. These “off-target” effects could not only impact patient survival but also provide valuable insights into the mechanisms of neurodegenerative diseases, paving the way for more effective therapies.

Did You Know? …

The average cost to develop a new drug and bring it to market is estimated to be $2.6 billion,according to a study by the Tufts Center for the Study of Drug Progress. repurposing existing drugs can drastically reduce these costs and timelines.

The Urgency of ALS treatment

ALS is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord, leading to muscle weakness, paralysis, and eventually, respiratory failure. The ALS Association estimates that approximately 5,000 people in the united States are diagnosed with ALS each year. With a typical survival time of two to five years after diagnosis, the need for effective treatments is urgent.

AI’s Role in “Synthetic Clinical Trials”

The emergence of EHRs has created unprecedented opportunities for medical research.Priyadip Ray, a staff scientist at LLNL, explains that the rarity and rapid onset of ALS make large clinical trials challenging. By using causal machine learning, researchers can create “synthetic clinical trials” by matching patients who were given a particular drug with similar patients who were not, effectively comparing outcomes and identifying potential treatments.

Pro Tip: …

When researching medical information online, always verify the source’s credibility. Look for reputable organizations, peer-reviewed studies, and expert opinions to ensure accuracy.

Promising Drug Candidates Identified

the research team analyzed data from over 20,000 veterans with ALS and identified three classes of drugs that showed a significant positive effect on survival: statins (cholesterol-reducing drugs), alpha-blockers (blood pressure medication), and PDE5-inhibitors (erectile dysfunction treatments). Notably,the combination of statins and alpha-blockers exhibited a synergistic effect,further enhancing their potential therapeutic benefits.

Future Research and Validation

To validate their findings and ensure broader applicability, the team plans to analyze millions of patient files from the Optum EHR dataset. They also intend to extend their AI/ML approaches to study Parkinson’s disease, hoping to uncover insights that could benefit the treatment of various neurodegenerative diseases. Securing funding for clinical validation is a crucial next step, which would not only pave the way for drug approval but also confirm the effectiveness of their AI-driven approach.
