Inclusion criteria

  1. Cohort-specific inclusion for male and female patients.

    a. Cohort A (no prior cranial radiation) i. Diagnosed with one of the following:

    • Breast cancer exposed to treatment including chemotherapy, radiotherapy, surgery and/or other breast cancer interventions.
    • Non-breast cancer patients exposed to anthracyclines- or platinum-containing chemotherapy within the past 3 years.
    • Non-breast cancer patients exposed to other anticancer therapies within the past 3 years.

      b. Cohort B (prior cranial radiation)

    • Previously received radiotherapy or radiosurgery to the brain for benign, malignant, or tumors.
    • > 6 months
  2. Washout from and conventional interventions is up to the discretion of the investigator. Concurrent participation in another intervention is allowable if judged by the Principal Investigator that this would not be scientifically or medically incompatible with this study.
  3. ≥18 years of age
  4. Perceived by patient or investigator that cognitive function has worsened since receipt of cranial radiation or cancer treatment.
  5. Able to provide .
  6. Literacy in English, Chinese, Korean, Vietnamese, or Spanish, to complete the questionnaires.
  7. Patients must agree to complete and be able to complete the questionnaires and computerized assessments used to measure functional outcomes.

    • Note: Patients who have visual impairment or have degenerative conditions (e.g. Parkinsons's disease, etc.) can participate if they cannot complete computerized assessments, as long as they can still complete the questionnaires with assistance.

Exclusion criteria

Exclusion Criteria:

  1. Cohort-specific exclusion for male and female patients:

    1. Cohort A (no prior cranial radiation)

      • History of or current presence of primary brain tumors or .
    2. Cohort B (prior cranial radiation)

      • Diagnosed with high grade glioma.
  2. Unwilling to undergo neuropsychological assessments necessary for the study.
  3. Women who are breastfeeding, pregnant or are planning to get pregnant during the study period. Persons of (POCBP) must have a negative pregnancy test at screening if there is suspicion of pregnancy.

    a. Female patients who are considered not to be of childbearing potential must have a history of being (with a minimum of 1 year without menses), tubal ligation, or hysterectomy.

  4. History of suspected to riluzole or to any of its .
  5. Patients taking or planned to take medications/substances with potential drug-drug interactions: pixantrone, current smoker (defined as having smoked within the last month), abametapir, cannabis, capmatinib, lapatinib, methotrexate, and levoketoconazole.
  6. Hepatic impairment as indicated by: or ALT ≥ 3x upper limit normal ()
  7. Have serious pre-existing medical conditions that, in the judgment of the investigator, would preclude participation in this study.
Terms in these criteria, in plain language(11)

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.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

What researchers measure

Primary outcomes

  1. Change in circulating Brain-Derived Neurotrophic Factor (BDNF) levels over time in cancer survivors experiencing cognitive impairment (CRCI)

    Comparing mean plasma BDNF values at each patient visit point, including before the intervention, at the midpoint, and at the endpoint of the study.

    Time frame: 8 weeks

Secondary outcomes

  1. Cognitive Function Scores (FACT-Cog)

    Functional Assessment of Cancer Therapy - Cognitive Function (FACT-Cog) scores, including both cumulative and perceived cognitive impairment scores. These scores will be compared between intervention and placebo groups over time, with mixed effects models used to evaluate changes.There are four other scoring subscales in FACT-Cog v3: perceived cognitive impairments (PCI; 18 items); perceived cognitive abilities (7 items); impact of perceived cognitive impairment on QOL (4 items); and comments from others on cognitive function (4 items). Both total and PCI scores will be calculated in this study. Total score is calculated by summing scores from all the items and ranges from 0-148, and higher scores represent better subjective cognitive functioning. Similarly, PCI score is calculated by summing responses of all relevant items and ranges from 0 to 72.

    Time frame: 8 weeks

  2. Cognitive Function Scores (CANTAB)

    The study will assess the effects of riluzole on cognitive function using the Cambridge Neuropsychological Test Automated Battery (CANTAB) scores across five cognitive domains. These scores will be compared between intervention and placebo groups over time, with mixed effects models used to evaluate changes. Cognitive domains of response speed, learning and memory, working memory, multitasking, and sustained attention will be assessed with CANTAB®. Using International Cognition and Cancer Task Force (ICCTF criteria), overall cognitive impairment is defined as ≥ 2 standard deviations below normative mean on at least 1 cognitive test or ≥ 1.5 standard deviations below normative mean on 2 or more tests.

    Time frame: 8 weeks
