Terms in these criteria, in plain language(19)

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.

Karnofsky performance status (KPS)

A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.

Studies often ask for 60 or 70 and above. Your doctor gives the score.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

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.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

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.

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.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

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.

Reproductive potential

Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.

Criteria about it usually ask for contraception during the study and for a time after it.

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.

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.

Excipients

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

TIA (transient ischaemic attack)

A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.

Stroke symptoms need emergency care at once, even if they go away.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

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.

What researchers measure

Primary outcomes

  1. Overall Survival (OS)

    Analyzed by the Kaplan-Meier method. OS is defined as the time from enrollment to death from any cause. Surviving patients are censored at last follow-up.

    Time frame: From enrollment to death from any cause, assessed up to 60 months.

Secondary outcomes

  1. Change in Quality of Life Score Assessed by the EORTC QLQ-BN20

    Quality of life is assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Brain Cancer Module (EORTC QLQ-BN20). The QLQ-BN20 contains 20 items, and scores are linearly transformed to a 0-100 scale. Higher scores indicate greater symptom burden/worse outcome. Changes in scores from baseline to post-treatment are analyzed.

    Time frame: Baseline and Week 4 post-treatment (4 weeks ± 7 days after the 4th treatment cycle; each cycle is 21 days).

  2. Incidence and Severity of Adverse Events

    All adverse events are graded and recorded according to NCI CTCAE v5.0. The incidence, severity, and causal relationship to the study drug are summarized.

    Time frame: From informed consent form (ICF) signing until 4 weeks after the last dose of study drug; assessed before each treatment cycle (each cycle is XX days), with summary at 4 weeks after the last dose.

  3. Intracranial Progression-Free Survival (iPFS)

    Analyzed by the Kaplan-Meier method. Intracranial progression is defined per RANO-BM criteria on contrast-enhanced T1-weighted brain MRI. Imaging assessments are performed every 2-3 months (each treatment cycle is 21 days).

    Time frame: From enrollment until the date of first documented intracranial progression per RANO-BM or death from any cause, whichever came first, assessed up to 60 months; imaging assessments every 2-3 months.

  4. Brain edema improvement rate

    Edema volume around target lesions is measured on T2/FLAIR sequences of brain MRI at baseline and post-treatment. Brain edema improvement is defined as a ≥25% reduction in edema volume from baseline. The response rate is calculated as: (number of patients with ≥25% reduction in edema volume / total number of evaluable patients) × 100%.

    Time frame: At Week 4 post-treatment (4 weeks ± 7 days after the 4th treatment cycle; each cycle is 21 days), i.e., the end-of-treatment assessment visit.

  5. Neurological Function Improvement Rate Assessed by Focused Neurological Examination

    Neurological function is assessed by focused neurological examination, including cranial nerve, motor, sensory, cerebellar, and reflex evaluations. Improvement is defined as resolution or stabilization of neurological deficits. The improvement rate is calculated as: (number of patients with improvement / total number of evaluable patients) × 100%.

    Time frame: Baseline and Week 4 post-treatment (4 weeks ± 7 days after the 4th treatment cycle; each cycle is 21 days).
