Clinical trials

Clinical trials are research studies that use human volunteers to test new therapies. After scientists test experimental therapies in the laboratory, those with promising results move to clinical trial to determine whether the therapy is safe and effective for use in humans. A new therapy must successfully pass through a series of phases before ultimately being approved by Health Canada and being made widely available to the Canadian public (learn more in our Clinical Trials FAQs).

In general, ALS clinical trials are therapeutic or observational in nature. Therapeutic clinical trials test potential drug therapies or interventional devices that aim to either slow the progression of the disease or help to manage symptoms. Observational trials aim to learn more about the disease and are essential to understanding, diagnosing and ultimately treating ALS. In many cases people who participate in clinical trials will not benefit from the therapy, but their generous involvement will help to find a successful therapy for those diagnosed in the future. One day, a clinical trial will test a therapeutic that slows the progression of ALS and those involved may directly benefit from taking part.

For more information, please speak with your clinician (preferably at an ALS clinic) and visit ClinicalTrials.gov, where all legitimate, recognized ALS clinical trials are registered globally. You can also visit the EU Clinical Trials Register and the World Health Organization International Clinical Trials Registry for additional information.

Current Clinical Trials for ALS in Canada

*NEW* Study of ANX005 in Adults With Amyotrophic Lateral Sclerosis (ALS)

Study: Therapeutic (Drug: ANX005); Phase 2
Status: Recruiting
Sites: Calgary, Edmonton, Toronto, Montreal (Neuro & CHUM), Fredericton
Sponsor: Annexon, Inc.

ANX005 is an antibody-based drug that targets a specific molecule, called C1q, within an inflammatory pathway called the complement system. Researchers hope that by inhibiting C1q they may be able to slow functional decline in people living with ALS. This Phase 2 clinical trial is open label with no placebo group, meaning everyone who enrolls in the study will receive the active drug. Approximately 24 participants will receive intravenous (IV) infusion of ANX005 over a 12-week period. Participants will be monitored to ensure that the drug is safe and to learn more about how the body breaks down the drug internally.

*NEW* Efficacy and Safety Study of Oral Edaravone Administered in Subjects With ALS

Study: Therapeutic (Drug: MT-1186); Phase 3b
Status: Recruiting
Sites: Edmonton, Saskatoon, Hamilton, London, Montreal (MNI), Greenfield Park, Fredericton
Sponsor: Mitsubishi Tanabe Pharma Development America, Inc.

In October 2018, a new treatment for ALS called edaravone (Radicava) was approved by Health Canada. Edaravone is typically delivered through intravenous (IV) infusion over several consecutive days, with 14 day breaks in between. In this new Phase 3b clinical trial, researchers will compare the effectiveness of two different dosing regimens of a new oral form of edaravone, called MT-1186. The study will enroll approximately 380 participants and last for 48 weeks. The effectiveness of oral edaravone at each dosing regimen will be measured primarily using the ALS Functional Rating Score Revised (ALSFRS-R), as well as certain breathing parameters and a questionnaire designed to evaluate aspects of health considered important by patients.

*NEW* Enoxacin for Amyotrophic Lateral Sclerosis (ALS) (REALS-1)

Study: Therapeutic (Drug: Enoxacin); Phase 1b/2
Status: Recruiting
Sites: Montreal (Neuro)
Sponsor: McGill University

This Phase 1b/2 clinical trial will test the safety and tolerability of enoxacin in people living with ALS. Enoxacin is an antibiotic that on a cellular level is known to activate an enzyme called DICER, which in turn can increase the levels of specific substances called microRNA (miRNA) which have been shown to be reduced in people living with ALS. The study will enroll approximately 36 participants who will be treated with enoxacin (taken by mouth) over a 30-day period. Researchers will monitor participants to ensure that the drug is safe, determine the appropriate dosage and learn more about how the body breaks down the drug internally. This study is being led by Canadian researcher Dr. Angela Genge (Montreal Neurological Institute-Hospital) in collaboration with Dr. Eran Hornstein (Weizmann Institute of Science). They are also the recipients of a 2020 ALS Canada-Brain Canada Discovery Grant which will allow them to will conduct more in-depth analyses to further assess the value of enoxacin in ALS.

*NEW* Radicava® (Edaravone) Findings in Biomarkers From ALS (REFINE-ALS)

Study: Observational
Status: Recruiting
Sites: Calgary, Toronto, Montreal (Neuro)
Sponsor: Mitsubishi Tanabe Pharma America Inc.

Biomarkers that can effectively measure neurodegeneration are much needed and essential to understanding, diagnosing, and ultimately treating ALS. In this observational study, researchers are seeking to identify and measure the levels of specific biomarkers in ALS patients being treated with edaravone (Radicava). The biomarkers of interest are linked to oxidative stress, inflammation, and neuronal and muscle injury. The study will enroll approximately 300 participants who will be followed over a 24-week period. Biological samples (blood and urine) will be collected from study participants for analyses. Participants can also opt in to receive their genetic results for five common mutations associated with ALS, including SOD1, TARDBP, C9ORF72, FUS and VCP.

*NEW* A Study to Assess the Safety, Tolerability, and Pharmacokinetics of BIIB105 in Participants With Amyotrophic Lateral Sclerosis

Study Type: Therapeutic (Drug: BIIB105); Phase 1
Status: Recruiting
Sites: Montreal (Neuro)
Sponsor: Biogen

BIIB105 (also referred to as ION541) is an antisense oligonucleotide (ASO) that is being studied to treat ALS. This is the first antisense treatment that has be designed to treat sporadic, rather than familial, forms of ALS. BIIB105 works to reduce production of a protein called ataxin 2 (ATXN2), which has been shown to impact the behaviour of another ALS-linked protein, TDP-43, that behaves abnormally in 97 per cent of people with ALS. It is hypothesized that lowering ATXN2 levels will help to restore the normal function of TDP-43, and therefore result in a therapeutic benefit. This Phase 1 study will enroll approximately 70 people living with ALS. Researchers will monitor participants to ensure that the drug is safe, determine the appropriate dosage and learn more about how the body breaks down the drug internally.

Evaluation of MN-166 (Ibudilast) for 12 Months Followed by an Open-label Extension for 6 Months in Patients With ALS (COMBAT-ALS)

Study Type: Therapeutic (Drug: Ibudilast); Phase 2b/3
Status: Recruiting
Sites: Hamilton, Toronto, Montreal (Neuro)
Sponsor: MediciNova

Ibudilast (also referred to as MN-166) is an experimental therapy being developed to treat ALS. This broad target drug is thought to reduce the activity of immune cells in the brain, thereby supressing inflammation. It is also believed to promote the production of neurotrophic factors which play a role in the growth and survival of motor neurons. The Phase 2b/3 COMBAT-ALS clinical trial will enroll 230 participants living with ALS and last 12 months. Researchers will monitor participants to ensure that the drug is safe. Researchers will also evaluate the impact of ibudilast on the progression of ALS by evaluating changes in the ALS Functional Rating Scale-Revised (ALSFRS-R) score, as well as muscle strength, quality of life, and respiratory function. Ibudilast will be taken by mouth in combination with a dose of riluzole. Researchers believe the anti-inflammatory and neuroprotective characteristics of ibudilast make it a promising treatment option for ALS.

Efficacy and Safety of Masitinib Versus Placebo in the Treatment of ALS Patients

Study Type: Therapeutic (Drug: Masitnib); Phase 3
Status: Not yet recruiting
Sites: TBD
Sponsor: AB Science

Masitinib is an oral drug that targets cells within the body that play an important role in the immune system. Previous studies suggest that masitinib may reduce inflammation within the nervous system that is thought to be a factor in the progression of ALS. A previous Phase 2/3 clinical trial showed that over a 48-week period, treatment with masitinib reduced loss of function and increased quality of life. This global Phase 3 clinical trial is intended to confirm the results of the previous Phase 2/3 study and is expected to enroll 495 participants in Canada, the US and Europe.

A Clinical Trial of Pimozide in Patients with Amyotrophic Lateral Sclerosis

Study Type: Therapeutic (Drug: pimozide); Phase 2
Status: Recruiting
Sites: Calgary, Edmonton, Fredericton, Hamilton, London, Ottawa, Toronto, Greenfield Park, Montreal (CHUM)
Sponsor: University of Calgary
Collaborators: ALS Canada, Brain Canada

Some people believe that the loss of muscle function that occurs in ALS is caused by the muscles and the nerves not being able to communicate anymore. The area in the body where this communication occurs is called the neuromuscular junction. Pimozide is a medication originally used in schizophrenia that has been shown to enhance communication at the neuromuscular junction in laboratory worms, fish and mice. This Phase 2 study will investigate whether treatment with pimozide slows the progression of ALS in humans. Pimozide will be evaluated primarily using the ALS Functional Rating Score Revised (ALSFRS-R), a 12-item questionnaire that assesses function in certain daily activities. This Phase 2 clinical trial is supported by an ALS Canada-Brain Canada Arthur J Hudson Translational Team Grant.

NeuroCognitive Communicator: Safety Study (NCC-1701)

Study Type: Therapeutic (Device: NeuroCognitive Communicator)
Status: Recruiting
Sites: Ottawa
Sponsor: Ottawa Hospital Research Institute

The progressive paralysis experienced by people living with ALS can eventually make communicating with others difficult as the ability to gesture and speak lessens with the weakening of the muscles. To help improve quality of life for people affected by ALS, researchers from the Ottawa Hospital Research Institute are testing the safety of a new assistive device that uses brain-computer interface (BCI) technology to help people who have motor impairments to communicate. This device can convert brain signals into single letters on a computer screen, allowing people to spell words simply with their thoughts. The technology requires surgical placement of two sensors into the areas of the brain that support motor and cognitive function. Researchers will be monitoring the two participants to ensure that the procedure is safe, and to assess the ability of this technology to support effective communication and improve quality of life.

Safety Study of Oral Edaravone Administered in Subjects With ALS

Study Type: Therapeutic (Drug: MT-1186); Phase 3
Status: Active, not recruiting
Sites: Edmonton, Montreal (Neuro), Greenfield Park, Quebec City
Sponsor: Mitsubishi Tanabe Pharma Development America, Inc.

In October 2018, a new treatment for ALS called edaravone (Radicava) was approved by Health Canada. The decision was based on evidence from a previous Phase 3 clinical trial which showed that edaravone helped to slow functional decline in participants who were early in their ALS progression, with milder symptoms and a larger vital capacity (the maximum amount of air a person can expel from their lungs after a maximum inhalation). Edaravone is delivered through intravenous (IV) infusion over several consecutive days, with 14 day breaks in between. In this new Phase 3 clinical trial, researchers will enroll 150 participants to test the safety and effectiveness of a new oral form of edaravone (MT-1186) which can be taken by mouth. The trial is expected to last 48 weeks and all participants will be given the active drug meaning there will be no placebo group. The hope is that the oral form proves to be safe and can be delivered to the brain and spinal cord as effectively as the current IV form. Due to the relatively intensive dosing regimen recommended for edaravone, a treatment option like MT-1186 that can be taken orally could significantly improve quality of life for people living with ALS.

An Efficacy and Safety Study of Ravulizumab in ALS Participants (CHAMPION-ALS)

Study Type: Therapeutic (Drug: Ravulizumab); Phase 3
Status: Active, not recruiting
Sites: Edmonton, Saskatoon, London, Toronto, Montreal (Neuro), Quebec City, Fredericton
Sponsor: Alexion Pharmaceuticals

Ravulizumab (also referred to as Ultomiris) is a drug that contains an antibody that targets a specific protein within the immune system, called C5, which is thought to play a role in the onset and progression of ALS. Researchers hope that by blocking this protein they may be able to slow disease progression. CHAMPION-ALS is a global Phase 3 clinical trial that will evaluate the safety and effectiveness of ravulizumab in 350 participants with familial (inherited) or sporadic ALS. The treatment will be administered through intravenous (IV) infusion every 8 weeks for a total of 50 weeks. The drug’s effectiveness will be measured primarily using the ALS Functional Rating Score Revised (ALSFRS-R), a 12-item questionnaire that assesses function in certain daily activities. Additional outcomes that will be monitored include changes in muscle strength, breathing parameters, and levels of neurofilament light chain (a biomarker of disease severity). Once the trial is completed all participants will have the opportunity to receive ravulizumab in a two-year open-label extension phase.

An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)

Study Type: Therapeutic (BIIB067); Phase 3
Status: Active, not recruiting
Sites: Calgary, Toronto, Montreal (Neuro)
Sponsor: Biogen
Collaborator: Ionis Pharmaceuticals, Inc.

*Due to the specificity of this treatment, this clinical trial is only open to individuals with a SOD1 mutation.   

BIIB067 (also referred to as tofersen) is an antisense oligonucleotide (ASO) that is being studied to treat a familial form of ALS linked to mutations in the SOD1 gene. As a result of mutation, SOD1 is believed to gain a toxic function that is damaging to the nerve cells that control movement. BIIB067 is designed to decrease production of SOD1 which researchers hope will lead to preservation of motor neurons and slowed progression of the disease. This Phase 3 clinical trial will enroll 144 participants with a confirmed SOD1 mutation and will test the safety, tolerability and effectiveness of BIIB067. This study is a continuation of a previous Phase 1/2 clinical trial which showed promising results.

A Study to Assess the Safety, Tolerability, and Pharmacokinetics of BIIB078 in Adults With C9ORF72-Associated Amyotrophic Lateral Sclerosis

Study Type: Therapeutic (BIIB078); Phase 1
Status: Active, not recruiting
Sites: Calgary, Edmonton, London, Toronto, Montreal (Neuro & CHUM)
Sponsor: Biogen

*Due to the specificity of this treatment, this clinical trial is only open to individuals with a C9ORF72 mutation. 

BIIB078 is an antisense oligonucleotide (ASO) that is being studied to treat a familial form of ALS linked to mutations in the C9ORF72 gene. Approximately 34% of all familial ALS cases are linked to C9ORF72, making it the most common genetic cause of ALS. Two substances are produced in cells as a result of C9ORF72 mutations, commonly referred to as repeat RNAs and DPR proteins. These substances are thought to contribute to the cellular toxicity that leads to disease. BIIB078 is designed to target repeat RNAs preventing them from being used to create the potentially toxic DPR proteins. This Phase 1 clinical trial will enroll 80 participants with a confirmed C9ORF72 mutation. Researchers will monitor participants to ensure that the drug is safe, determine the appropriate dosage and learn more about how the body breaks down the drug internally.
