This is a Phase 1, first‑in‑human study testing a single intravenous dose of SynKIR-310 in people with relapsed or refractory B‑cell non‑Hodgkin lymphoma. The study will escalate doses in up to four small cohorts to find a recommended Phase 2 dose, then enroll more participants at that dose. Overall, up to 36 participants will be treated; the study focuses on safety, feasibility, and early signs of activity.

What it is studying. The study is testing the safety and feasibility of a single infusion of SynKIR-310 and collecting early data on its activity and how long the modified T cells persist in blood. It also aims to identify a recommended dose for future studies.

What the researchers hope to learn. Scientific goals are to evaluate safety (including adverse events and dose‑limiting toxicities), confirm feasibility of giving SynKIR-310, determine a Recommended Phase 2 Dose, and collect preliminary measures of response, duration of response, and product persistence.

What this study is about

The study's own summary, as published on ClinicalTrials.gov. Underlined terms have a short explanation.

This first-in-human (FIH) trial is designed to assess the safety, feasibility and preliminary efficacy of a single intravenous (IV) dose of SynKIR-310 administered to participants with relapsed/refractory B-NHL.

Study description and what participation involves

The study's detailed description, as published on ClinicalTrials.gov.

Detailed description from the registry

This is a Phase 1, FIH, multicenter, open-label study of a single infusion of SynKIR-310 in participants with relapsed/refractory B-NHL. Up to 36 participants, regardless of subtypes of B-NHL, who meet the eligibility criteria, will be treated in the study. Up to 4 cohorts of 3 to 6 participants per cohort will be assessed to determine the safety and feasibility of treatment with SynKIR-310. Doses will be escalated across up to 4 cohorts to determine a Recommended Phase 2 Dose (RP2D). Once the RP2D has been determined, a dose expansion group will enroll additional participants regardless of subtypes of B-NHL at the RP2D to further characterize the safety, feasibility and preliminary efficacy of SynKIR-310 in treating B-NHL.

Participants will have screening tests. If eligible, they receive a single intravenous (IV) infusion of SynKIR-310, a treatment made from their own T cells that have been genetically modified to target CD19. The registry also mentions leukapheresis, a blood-cell collection procedure, but does not describe when or how it is performed in the study. After infusion, blood samples will be taken at multiple times to measure CAR T‑cell persistence and for safety testing, and investigators will assess disease response. Participants will be monitored for adverse events and followed for safety and outcomes for up to 24 months; some screened participants may not ultimately receive the infusion.

How the study is structured. Phase 1, open‑label, single‑group interventional trial. Participants receive one IV infusion of SynKIR-310 (autologous T cells transduced with CD19 KIR‑CAR). Doses will be escalated across up to four cohorts (3–6 participants each) to determine a Recommended Phase 2 Dose (RP2D), after which a dose expansion group will enroll additional participants at the RP2D. Safety, feasibility, response, and persistence of the product will be followed for up to 24 months.

Questions you could ask

These questions are suggestions for a conversation with the study team or your own clinician, not advice.

  • This is an early-phase study, mainly about safety and dose. What is already known about this treatment?
  • The listed sites are in United States. Is any of them reachable for me, and does the study help with travel?
  • Which of the eligibility criteria would need to be checked with tests before I could join?

Terms used on this page · explanations by MedicalUpdates.ai

first-in-human
The first study in which a treatment is given to people. Safety is the main question and the number of participants is usually small.
relapsed/refractory
A condition that has not responded to a treatment. 'Relapsed' means it responded and then came back; 'refractory' means it did not respond in the first place.
Histologically confirmed
Removal of a small piece of tissue so it can be examined under a microscope. 'Biopsy-proven' or 'histologically confirmed' means the diagnosis was confirmed by examining tissue under a microscope.
enrollment
The number of participants a study plans to include, or has included. 'Estimated' means the planned number; 'actual' means the number who joined.
CAR T
A treatment in which a person's own immune cells (T cells) are collected, modified in a laboratory to recognise a target, and returned to the body.
relapsed
A condition that improved with treatment and has since returned or worsened.
prior lines
Treatment a person has already had for the condition. A 'line of therapy' is one course of treatment; studies often require, or limit, the number of prior lines.
allogeneic stem cell transplant
A procedure that replaces blood-forming cells after high-dose treatment. 'Autologous' uses the person's own cells collected beforehand; 'allogeneic' uses cells from a donor.
immunosuppressive
A medicine that reduces the activity of the immune system. Studies of autoimmune conditions often require a stable dose, a prior failure, or a washout of such medicines.
ECOG
A scale from 0 to 5 that describes how a person's condition affects daily activity. 0 means fully active; 1 means restricted in strenuous activity; 2 means able to self-care but unable to work; higher numbers mean more limitation.
investigational agent
A treatment that is being tested and has not been approved for this use. It may be approved for a different condition. Being studied does not mean it works or is available outside the study.
prior to screening
The checks done before enrolment to see whether a person qualifies, such as tests, scans or a review of medical history.
complete remission
No sign of the condition can be found with the tests used in the study. It does not always mean the condition is gone permanently, and the definition depends on the condition and the study.
Exclusion criteria
The conditions that rule a person out even if they meet the inclusion criteria, for example other illnesses, certain medicines or pregnancy.
Inclusion Criteria
The conditions a person must meet to be considered for the study, for example a confirmed diagnosis, an age range or a test result.
open-label
No masking is used, so the assigned intervention is not deliberately hidden from participants or study staff.
eligibility criteria
The rules the study team uses to decide who may take part. They are usually split into inclusion criteria and exclusion criteria.
cohort
A group of people who share a characteristic, such as a diagnosis, and are studied together. 'Prospective' means they are followed forward from enrolment; 'retrospective' means existing records are reviewed.
Recommended Phase 2 Dose
The dose chosen at the end of a phase 1 study for testing in later studies, based on safety and other measurements.
