Full Study Summary:

AMX0035 is a combination therapy designed to reduce neuronal death through blockade of key cellular death pathways originating in the mitochondria and endoplasmic reticulum (ER). This clinical trial is designed to demonstrate that treatment is safe, tolerable, and able to slow decline in function as measured by the ALSFRS-R. The trial will also assess the effects of AMX0035 on muscle strength, vital capacity, and biomarkers of ALS including markers of neuronal death and neuroinflammation.

Key Exclusion Criteria:
Presence of tracheostomy
Exposure to PB, TUDCA or UDCA within 3 months prior to the Screening Visit or planning to use these medications during the course of the study
History of known allergy to PB or bile salts
Abnormal liver function defined as AST and/or ALT > 3 times the upper limit of the normal

Poorly controlled arterial hypertension (SBP>160mmHg or DBP>100mmHg) at the Screening Visit
Pregnant women or women currently breastfeeding
History of cholecystectomy
Biliary disease which impedes biliary flow including active cholecystitis, primary biliary cirrhosis, sclerosing cholangitis, gallbladder cancer, gallbladder polyps, gangrene of the gallbladder, abscess of the gallbladder.
History of Class III/IV heart failure (per New York Heart Association - NYHA)
Severe pancreatic or intestinal disorders that may alter the enterohepatic circulation and absorption of TUDCA including biliary infections, pancreatitis and ileal resection
The presence of unstable psychiatric disease, cognitive impairment, dementia or substance abuse that would impair ability of the subject to provide informed consent, according to Site Investigator judgment
Clinically significant unstable medical condition (other than ALS) that would pose a risk to the subject if they were to participate in the study
Active participation in an ALS clinical trial evaluating a small molecule within 30 days of the Screening Visit
Exposure at any time to any biologic under investigation for the treatment of subjects with ALS (off-label use or investigational) including cell therapies, gene therapies, and monoclonal antibodies.
