A scientist within the RCH4 charity discovered and identified a problem protein that is responsible for promoting ALS in over 80% of PALS. This problem protein was previously unknown by researchers around the world. The RCH4 charity then designed a drug that can safely stop the production of this problem protein with no known side effects in patients.
The Internet forum Patients Like Me, discusses the efficacy and safety of the drug. Monitoring reports by PALS from fourteen countries using RCH4 are submitted to the charity every month and have been over the course of several years.
