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.
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.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
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.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
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.
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.
Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
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.

Change From Baseline in Health-Related Quality Of Life (HRQoL) on Functional Assessment of Cancer Therapy Lymphoma (FACT-Lym) Trial Outcome Index (TOI) Score
The FACT-Lym is a 42-item questionnaire designed to measure HRQoL and cancer-specific symptoms in non-Hodgkin lymphoma patients. Subscales include FACT-General (FACT-G), FACT-Trial Outcome Index (FACT-TOI), FACT-Lym total score (FACT-Lym TS), and the Lymphoma subscale (Lym S). The Lym S has a single domain consisting of 15 items specific to lymphoma burden with a score ranging from 0 to 60. FACT-G has 4 well-being domains, physical (7 items), social/family (7), emotional (6), and functional (7), with scores ranging from 0 to 108. FACT-TOI combines FACT-G's physical and functional domains with Lym S, with scores ranging from 0 to 116. FACT-Lym TS combines FACT-G with Lym S, with scores ranging from 0 to 168. The scoring of FACT-Lym is on a 5-point Likert scale from 0 to 4, with 0= not at all, 1= a little bit, 2= somewhat, 3=quite a bit, 4=very much. The higher the score the better the quality of life.

Change From Baseline in HRQoL on Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-NTX) Neurotoxicity Subscale Score
The FACT GOG-NTX provides a targeted assessment of symptoms of peripheral neuropathy, including sensory, motor, and auditory problems and cold sensitivity. It is an 11-item questionnaire designed to measure the neurotoxicity subscale. The scoring of FACT GOG-NTX is on a 5-point Likert scale from 0 to 4, with 0= not at all, 1= a little bit, 2= somewhat, 3=quite a bit, 4=very much. To produce a Neurotoxicity Subscale score (range 0-44), multiply the sum of the item scores by the number of items in the subscale, then divide by the number of items answered.
