Study of WVE-004 in patients with C9orf72-associated Amyotrophic Lateral Sclerosis (ALS) or Frontotemporal Dementia (FTD)
Information about the drug that will be tested in the study
The study drug is given as an injection through a thin needle into the spinal canal (lumbar puncture).
Is the drug already on the market for another medical condition?
Will all participants receive the same drug?
Participants will be selected at random to either receive one of the following options:
- WVE-004 (Dose A, B, C or D)
- Placebo (also called a dummy treatment which is an inactive substance identical in appearance to the drug being tested with no active therapeutic effect).
Neither the participant nor his/her doctor will know if the person is receiving the investigational drug or the placebo.
Information about participating in the trial
What are the researchers trying to find out?
The purpose of this study is to evaluate the safety and tolerability of WWE-004 in adults with documented mutation in the C9orf72 gene (GGGGCC repeat expansion) who have been diagnosed with Frontotemporal Dementia or Amyotrophic Lateral Sclerosis.
How long will the treatment last?
What your involvement will entail?
- During the study, participants will be asked to complete some laboratory/biological tests to evaluate the emergent adverse effects (unfavourable signs, symptoms or diseases temporally associated with the use of the drug tested in the study) as well as to understand how WVE-004 moves through and impact the body
- Participants with Frontotemporal Dementia and its study partner will complete a test called CDR® plus NACC FTLD, which assesses memory, orientation, judgement, problem solving, personal care, community affairs, behaviour, and language
- Participants will be asked to undertake brain scans (MRI) or lumbar punctures (for CSF sampling and administration of study drug) to see changes in biomarkers in the brain. Participants with mixed disease (Amyotrophic Lateral Sclerosis and Frontotemporal Dementia) need not undergo MRI if their Amyotrophic Lateral Sclerosis symptoms prevent it.
Further information on the procedures, tests and number of visits can be obtained from the study team.
Who can participate in this study?
Who can participate in the study?
To take part in the study, participants must:
- Be between 18 and 80 years old
Participants with Frontotemporal Dementia must:
- Have a score of 0.5 or 1 in the Clinical Dementia Rating-Global Score- Frontotemporal Lobar Degeneration (CDR® plus NACC FTLD). This would suggest that the person has an impairment in their memory that is at a very mild stage
- Able to undergo brain scans and lumbar puncture
Participants with Amyotrophic Lateral Sclerosis must:
- Be diagnosed with Amyotrophic Lateral Sclerosis based on clinical disease
- Clinically diagnosed possible, laboratory supported probable, probable, or definite criteria for diagnosing Amyotrophic Lateral Sclerosis according to the World Federation of Neurology revised El Escorial criteria
- If the participant is taking riluzole, the dose must be stable for ≥30 days
- If the participant is taking edaravone, he must have received it for a minimum of 1 cycle (28 days).
Participants with mixed disease (Amyotrophic Lateral Sclerosis and Frontotemporal Dementia) must:
- Meet above criteria for both Amyotrophic Lateral Sclerosis and Frontotemporal Dementia.
Who cannot participate in the study?
People cannot take part in the study if they have or have experienced:
- A disease or medical condition that may interfere with the study assessments and will make the participant unsuitable for participation in or completion of the trial procedures
- Any other investigational drug, biological agent, or device within 1 month and received an investigational oligonucleotide, within the past 6 months.
The above list is not exhaustive.
