Study details:

This study uses an innovative multi-arm, adaptive trial design to investigate the efficacy of multiple treatments simultaneously. Currently one study-arm is active, investigating the efficacy and safety of lithium carbonate versus placebo in patients with ALS. Only patients with a specific UNC13A genotype (approximately 1 in 6 ALS patients) are eligible to participate.

The use of riluzole will be permitted during the study. Subjects taking riluzole must be on a stable dose for at least 30 days prior to the baseline visit, or stopped taking riluzole at least 30 days prior to the baseline visit.

Women of childbearing potential* must have a negative pregnancy test at baseline and be non-lactating.

Men must not plan to father a child or to provide sperm for donation for the duration of the trial and 3 months after the last dose of study drug.

Women must not be able to become pregnant (e.g. post-menopausal***, surgically sterile or using effective birth control methods) for the duration of the study. Effective contraceptives are defined as having a failure rate of less than 1% per year when used consistently and correctly and, when applicable, in accordance with the product label, including: abstinence, hormonal contraception, intrauterine device in place for ≥ 3 months Appendix 1). Women of childbearing potential must have a negative pregnancy test at baseline, and be non-lactating. Women who are pregnant or are actively seeking to become pregnant, and women of reproductive potential who are not using effective contraceptives are excluded.

Exclusion criteria

Laboratory Criteria at baseline: * ALT (alanine transaminase) ≥ 5 times upper limit of normal (ULN) * AST (aspartate aminotransferase) ≥ 3 times ULN * Bilirubin ≥ 1.5 times ULN * Estimated glomerular filtration rate (eGFR) < 50 mL / min / 1.73 m2 based on Cystatin C, if not available eGFR can also be calculated based on creatinine clearance. * Platelet concentration of < 100 x109 per L * Absolute neutrophil count of < 1x109 per L * Haemoglobin < 100 g/L (<6.2 mmol/L) * Amylase & lipase ≥ 2 times ULN (suspected pancreatitis) * Lactate ≥ 2 times ULN (suspected lactate acidosis)

Moderate to severe hepatic impairment according to Child-Pugh classification (Class B or higher; score ≥ 7). Child-Pugh classification is based on bilirubin, albumin, International Normalized Ratio (INR) and presence of encephalopathy or ascites.

Participation in any other investigational drug trial or using investigational drug (within 30 days prior to screening).

Hypothyroidism unresponsive to thyroid hormone supplementation.

Subjects using non-invasive ventilation (NIV, ≥22 h per day) or having a tracheostomy.

Subjects taking edaravone within 30 days prior to screening. Edaravone is approved by the FDA, but remains an investigational product in Europe and Australia.

Clinically significant history of unstable or severe cardiac (e.g. congestive heart failure, coronary insufficiency and arrhythmias), oncological, hepatic or renal disease, neuromuscular diseases, significant pulmonary disorder or other medically significant illness.

Drug or alcohol abuse.

Unstable psychiatric illness defined as psychosis or untreated major depression within 90 days of the screening visit. This exclusion criterion is based on a prior psychiatric diagnosis that is unstable as determined by the subject's treating Psychiatrist.

Presence of frontotemporal dementia which prevents informed consent.

Patients heterozygous or homozygous for the A-allele of rs12608932 (UNC13A)

Known allergy or hypersensitivity to lithium, or its excipients, or to the components of the placebo.

Brain injury with posttraumatic epilepsy or neurologic deficit, excluding a concussion in the medical history. Brain infarction is an exclusion criterion, a transient ischemic attack is not.

Addison disease.

Patients with the following co-medication: antipsychotics, digoxin and calcium antagonists, carbamazepine, methyldopa, verapamil and diltiazem.

Brugada Syndrome or family history of Brugada Syndrome.

Plasma sodium <120 mmol/L

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

How is the study designed?

Participant Group/Arm	Intervention/Treatment
EXPERIMENTAL: Lithium carbonate Lithium carbonate 400 mg capsules will be taken once daily, starting with one capsule (400 mg daily) initially titrated up to two or three capsules daily, depending on blood lithium levels. The target range for the lithium plasma level will be between ≥0.4 mmol/l and ≤ 0.8 mmol/l. Maximum duration is 24 months.	DRUG: Lithium Carbonate 400 MG Lithium carbonate vs placebo (2:1)
PLACEBO_COMPARATOR: Placebo Patients start with 1 capsule to be taken once daily, with subsequent sham dose adjustments made to patients on placebo to maintain blinding in clinical sites.	DRUG: Lithium Carbonate 400 MG Lithium carbonate vs placebo (2:1)

What is the study measuring?

Primary outcome

Primary Outcome Measure	Primary Outcome Description	Primary Outcome Time Frame
Overall survival, defined as time to death from any cause or respiratory insufficiency (DRI; defined as tracheostomy or the use of non-invasive ventilation for ≥22 h per day for ≥10 consecutive days)	A tracheostomy for ventilation is meant here	endpoint or 24 months

Secondary outcome

Composite endpoint evaluating daily functioning and survival based on the joint model framework of survival and longitudinal ALSFRS-R total scores	The ALSFRS-R (Amyotrophic Lateral Sclerosis Rating Scale-revised) is a 12 item participant self-report measure that monitors ALS disease progression, where a higher score reflects a better outcome.	endpoint or 24 months
