The treatment, AMX0035 (marketed as Albrioza), is composed of two drugs—tauroursodeoxycholic acid and sodium phenylbutyrate—that protect nerve cells by blocking stress signals within mitochondria and protein-synthesizing organelles called endoplasmic reticula, according to ALS News Today.

The Times reports that, to date, the treatment’s effectiveness has been measured in a Phase 2 clinical trial involving 137 participants, as well as an open-label extension study, which ...
