Neurodegenerative Alzheimer's Disease and Amyotrophic Lateral Sclerosis (NADALS) Basket Trial
United States17 participantsStarted 2022-12-05
Plain-language summary
This is an open-label, biomarker-driven basket trial of baricitinib in people with subjective cognitive disorder, mild cognitive impairment, Alzheimer's disease (AD), Amyotrophic lateral sclerosis (ALS), or asymptomatic carriers of an ALS-related gene, such as a hexanucleotide expansion in the C9ORF72 gene, with evidence of abnormal inflammatory signaling in cerebrospinal fluid (CSF) at baseline. Each participant will be treated with baricitinib for 24 weeks; no placebo will be given. Participants will receive baricitinib 2 mg per day by mouth for the first 8 weeks and baricitinib 4 mg per day by mouth for the remaining 16 weeks. This proof of concept trial will ascertain whether baricitinib at 2 mg per day, 4 mg per day, or both reaches therapeutic levels in the CSF and suppresses inflammatory biomarkers associated with type I interferon signaling among the study participants.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
CSF Concentration of baricitinib
Timeframe: Measured at baseline, 8 weeks and 16 weeks, results reported at the completion of the study
2
CSF CCL2 Concentration
Timeframe: Measured at baseline, 8 weeks and 16 weeks, results reported at the completion of the study
. Ability to medically undergo LP in the opinion of the investigator (e.g., no bleeding disorder, allergy to local anesthetics, prior lumbar surgery which might make LP difficult, a skin infection at or near the LP site, evidence of high intracranial pressure, or anticipated difficulty getting into position for LP).
. Capable of providing informed consent and following study procedures.
. Women who are pregnant, breastfeeding, or planning to become pregnant during the trial
. Any unstable clinically significant medical condition other than ALS or AD (e.g., within six months of baseline, including but not limited to myocardial infarction, angina pectoris, congestive heart failure, or neoplasm undergoing active treatment).
. Active cancer or history of cancer, except for the following: basal cell carcinoma, cervical carcinoma in situ, prostatic carcinoma in situ, or other malignancies curatively treated and with no evidence of disease recurrence for at least 5 years. Active cancer includes cancers with current disease manifestations or therapy that could adversely affect participant safety and longevity, create the potential for drug-drug interactions, or compromise the interpretation of study results.
. History of diverticulitis or bowel perforation.
. Active ulcerative colitis, Crohn's disease, and history of peptic ulcer disease within the past 5 years or after the age of 65.
. Active, serious infection, including localized infection in the opinion of the investigator.
