A Phase 1 interventional study of KUR-502 in NHL, Relapsed, Adult, B-cell Lymphoma and B-cell Leukemia, sponsored by Athenex, Inc.. Recruiting at 3 sites in United States. Open to participants aged 3 Years to 75 Years. Per ClinicalTrials.gov, last updated 2023-05-18.
Sponsored by Athenex, Inc. · Phase 1, Interventional, and Treatment
This study is a multi-center study to evaluate the safety of KUR-502 in subjects with refractory/relapsed B-cell NHL or leukemia (ALL or CLL).
KUR-502 will be manufactured from leukapheresis products from healthy donors. Subjects will be enrolled into 2 parallel cohorts (Cohort A [non-ALL] and Cohort B [ALL]). Each cohort will undergo dose escalation independently.
Three (3) dose levels will be evaluated in the ANCHOR and ANCHOR2 studies combined (1×107/m2, 3×107/m2, 1×108/m2). Dose levels are defined based on the number of transduced KUR-502 cells. Body surface area (BSA) will be capped at 2.4 m2. Subjects will receive \<1×104 allogeneic T cells/kg at any dose level.
The MTD will be determined once dose escalation is completed, and all subjects are evaluable for DLT. If there is no DLT that determines an MTD, a maximum dose level will be declared. Dose escalation will stop when 6 subjects have been treated at the MTD or highest dose level.
885 studies on the registry are indexed under Lymphoma, B-Cell; 286 are open to participants now.
This study's planned enrollment of 36 is close to the median of 34 across 773 interventional studies indexed under Lymphoma, B-Cell.

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.
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.
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.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.
“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.
Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
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.
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.
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.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
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.
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.
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.
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.
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.
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.
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.

Genetic: KUR-502
KUR-502 (CD19.CAR-aNKT cells) consists of transduced allogeneic natural killer T cells (aNKT) genetically modified with additional features to enhance their anti-tumor activity against CD19+ B-cell malignancies. Following intravenous (IV) infusion, the product is expected to kill CD19+ tumor cells by direct interaction with the chimeric antigen receptor (CAR), and activation of the NKT cells to kill tumor through their innate cell killing.
Also known as: CD19.CAR-aNKT cells

Started Oct 2022 (actual). Primary completion is estimated for Dec 2023, 14 months after the start.
Of 90 industry-sponsored phase 1 interventional studies under Lymphoma, B-Cell, half reached primary completion within 47 months of starting (the median), counting those still running; a quarter within 37 and three quarters within 81. This study's planned 14 months is below that.
Counting every sponsor, half of 207 studies reached it within 51 months; a quarter within 37 and three quarters within 78.
