Summary

This trial tests baricitinib, a pill taken daily, in people with early signs of Alzheimer's or ALS, or those at risk. The goal is to see if it can reduce harmful inflammation in the brain. Participants will take the medication for several months to check if it reaches the brain and lowers inflammation. Baricitinib is used for the treatment of rheumatoid arthritis and has shown promising preliminary data for moderate-to-severe atopic dermatitis.

Who is the study for?
Adults aged 55-90 with cognitive issues like Alzheimer's or mild impairment, and those aged 18-80 with ALS or carrying an ALS-related gene. Participants must have up-to-date vaccinations including Shingrix and COVID-19, be able to consent, and for those with AD, a MoCA score ≥8 plus a study partner is required. For ALS patients: stable on FDA treatments if any, able to walk at home daily, and life expectancy over 12 months.
What is being tested?
The trial tests baricitinib in participants with various neurodegenerative conditions over 24 weeks without using a placebo. It starts at a lower dose for the first eight weeks before doubling. The goal is to see if it can reach therapeutic levels in the brain/spinal fluid and reduce inflammation markers linked to these diseases.
What are the potential side effects?
Baricitinib may cause infections due to immune system suppression, changes in blood test results indicating liver or kidney issues, cholesterol increases, allergic reactions where the drug enters the body (if injected), digestive tract problems like diverticulitis or ulcers.

Prior Approvals
Other Research
Common treatments for Amyotrophic Lateral Sclerosis (ALS) include medications like Riluzole and Edaravone, which work by reducing glutamate-induced excitotoxicity and oxidative stress, respectively. Baricitinib, a Janus Kinase (JAK) inhibitor, is being studied for its potential to suppress inflammatory pathways that contribute to motor neuron degeneration in ALS. By inhibiting JAK1 and JAK2, Baricitinib may reduce the inflammatory signaling that exacerbates neuronal damage. This is crucial for ALS patients as it targets the underlying inflammatory processes, potentially slowing disease progression and improving quality of life.
