Inclusion criteria

  • Clinical diagnosis of ALS, locked-in syndrome, or stroke

    1. ALS - ALS patients who in the opinion of the treating neurologist have at least 3 years of survival
    2. Locked-in Syndrome as a result of brain-stem stroke or traumatic brain-stem injury - patients who in the opinion of the treating neurologist have at least 3 years of survival
    3. Stroke (either ischemic or hemorrhagic) - for patients with prior stroke, the original cause of the stroke (e.g., arteriovenous malformation, carotid stenosis, atrial fibrillation, heart disease, hypertension) must have been addressed and the patient must not have had a recurrent stroke at least within the prior 12 months
  • ALS diagnosis, stroke, or Locked-in syndrome (LIS) etiology onset occurred at least one year prior to enrollment
  • Minimal communication ability as assessed by a speech-language pathologist

    1. unable to produce more than 10 total unique intelligible words when reading the Rainbow Passage and Grandfather Passage, and
    2. unable to write or type more than 10 unique words from a dictated list of 20 words.
  • Limited upper limb strength based on the Medical Research Council Scale for Muscle Strength

    1. ≤3/5 strength throughout both arms for those with non-progressive conditions (stroke or traumatic brain-stem injury)
    2. ≤4/5 strength throughout both arms for those with ALS

    i. For patients with 4/5 strength, they must have a documented decline in speech or upper extremity function in the preceding 12 months.

  • Has a means of communication sufficient to enable understanding of research protocol and provide consent (e.g. eye blinks or eye movements, use of assistive technology). Thus patients are severely impaired with regards to naturalistic communication, but able to make decisions regarding their own care
  • Ability to understand and comply with study session instructions
  • Must live within a 90-minute drive of study site and willing to travel to study site up to three days per week for duration of the study
  • Has a stable psychosocial support system with caregiver capable of providing care during post-operative periods and monitoring participant throughout the study
  • Stable ventilator status - ventilator requirements have not changed over prior 6 months and ventilator status does not impose additional substantial risks to subject participation, including travel to the investigation site

Exclusion criteria

Exclusion Criteria:

  • Psychiatric conditions including current diagnosis of major psychiatric illness, significant cognitive impairment (based on a neuropsychological assessment by a clinical psychologist), suicidal ideation with intent/plan. [Columbia-Suicide Severity Rating Scale (C-SSRS) Categories 4-5)] or suicidal behavior within 12 months, or substance abuse/narcotic/alcohol dependence within 12 months.
  • Neurological disorders including current diagnosis of epilepsy, abnormal pre-surgical neuroimaging precluding safe implant placement (per neurosurgical team), prior ipsilateral craniotomy, or hydrocephalus with or without ventricular shunt.
  • Implanted electronic devices including pacemakers, cardiac defibrillators, spinal cord stimulators, vagal nerve stimulators, deep brain stimulators, or cochlear implants.
  • Cardiovascular disorders including acute myocardial infarction (MI) or cardiac arrest within 6 months, significant cardiovascular impairment contraindicating surgery.
  • Hematological disorders requiring chronic anticoagulation and medical to discontinuing anticoagulant medications perioperatively.
  • Dermatological conditions causing excessive skin sloughing, poor wound healing, existing scalp lesions, or skin breakdown.
  • Infectious/immunological conditions including active infections, unexplained fever, infection, ongoing chronic infections, medical conditions predisposing to high infection risk, chronic or therapy, or active cancer within 1 year requiring chemotherapy.
  • Medical contraindications including conditions contraindicating chronically implanted devices (osteomyelitis, diabetes, hepatic failure, disease/disorders with associated altered immune responses) or other chronic unstable medical conditions interfering with participation.
  • Surgical contraindications including medical contraindications to general anesthesia, craniotomy, or surgery; significant pulmonary, metabolic, or renal impairments making surgical procedure unsafe.
  • Other exclusions including pregnancy (confirmed by blood test), nursing, inadequate , correction vision worse than 20/100, limited English proficiency, or concurrent participation in device/drug trials.
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

Primary outcomes

  1. Safety as assessed by the number and type of adverse events that occur

    Time frame: From time of implant to one year post-implant

Secondary outcomes

  1. Safety as assessed by the number of participants with device explanted

    Time frame: From time of implant to one year post-implant

  2. Safety as assessed by the number of participants with Serious Adverse Events that result in death or permanently increased disability

    Time frame: From time of implant to one year post-implant

  3. Effectiveness of the device as assessed by the Word error rate (WER)

    Time frame: Every three months for the first two years post-implant

  4. Effectiveness of device as assessed by the Phoneme error rate (PER)

    Time frame: Every three months for the first two years post-implant

  5. Effectiveness of the device as assessed by the Bilingual Evaluation Understudy (BLEU) Score

    BLEU (Bilingual Evaluation Understudy) quantifies, on a range of 0-1, the overlap between the decoded text and the reference text based on matching n-grams. Higher BLEU scores indicate that the decoded output more closely matches the reference at the level of local word sequences.

    Time frame: Every three months for the first two years post-implant

  6. Effectiveness of the device as assessed by the Bidirectional Encoder Representations from Transformers (BERT) Score

    BERT Score compares the semantic similarity (on a range of -1 to 1) between the decoded text sequence and the reference text using a pretrained language model (BERT). Higher scores indicated stronger semantic alignment.

    Time frame: Every three months for the first two years post-implant

Timeline

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Nov 2026; primary completion for Jan 2035, 98 months later.

Of 134 non-industry interventional studies with no phase under Amyotrophic Lateral Sclerosis, half reached primary completion within 40 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 60. This study's planned 98 months is above that.

Counting every sponsor, half of 154 studies reached it within 35 months; a quarter within 23 and three quarters within 60.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
