Darifenacin for ALS
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to test the safety and effects of Darifenacin for people with ALS, a condition that affects nerves and muscles, leading to severe disability. Researchers hope Darifenacin will improve nerve connections and muscle function in ALS patients. Participants will receive either the drug or a placebo (a non-active pill) to compare results. Those diagnosed with ALS within the last three years and who can swallow tablets might be suitable for this study. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.
Will I have to stop taking my current medications?
If you are taking standard ALS medications like Riluzole, Edaravone, or Albrioza, you must be on a stable dose before starting the trial and continue that dose during the study. If you are taking certain other medications, like strong CYP3A4 inducers or inhibitors, or antimuscarinic medications, you may need to stop them before joining the trial.
Is there any evidence suggesting that Darifenacin is likely to be safe for humans?
Research has shown that Darifenacin is FDA-approved for treating overactive bladder, indicating its general safety for that condition. This study examines how well individuals with ALS, a progressive nerve disease, can tolerate Darifenacin. Past studies reported that participants tolerated the treatment well, experiencing mild side effects such as dry mouth and constipation. This ongoing study aims to confirm these results specifically for ALS patients.12345
Why do researchers think this study treatment might be promising for ALS?
Unlike the standard ALS treatments, which often include drugs like riluzole and edaravone that primarily aim to slow down disease progression, darifenacin offers a unique approach by potentially addressing symptoms more directly. Darifenacin is traditionally used to manage overactive bladder by blocking specific receptors that control muscle contractions. Researchers are excited about the possibility that this drug might help manage ALS symptoms by reducing unwanted muscle activity, offering a new way to improve quality of life for patients. This different mechanism of action sets darifenacin apart, providing hope for a novel method of symptom management in ALS.
What evidence suggests that Darifenacin might be an effective treatment for ALS?
Research has shown that Darifenacin, which participants in this trial may receive, might help treat ALS by targeting specific parts of the body. This drug may aid certain cells, called glial cells, in repairing themselves. These cells play a crucial role in maintaining healthy nerve connections. In studies with mice that had ALS, these cells began to repair when given Darifenacin, suggesting it might also help protect nerve connections in humans. Although more research is needed, these findings offer hope that Darifenacin could improve muscle function and quality of life for those with ALS.12567

Are You a Good Fit for This Trial?
This trial is for people aged 18-85 with ALS, a progressive neurological disorder. Participants will be taking Darifenacin or a placebo to see if it can help maintain nerve and muscle connections by influencing certain cells at the neuromuscular junction.Inclusion Criteria
