LUMC-BOB1-B7-TCR.1

Clinical trials are investigating LUMC-BOB1-B7-TCR.1 in people with relapsed or refractory B-cell cancers. These studies aim to check whether treatment can be made, given safely, and help patients respond. The main target group includes HLA-B*07:02-positive patients with B-cell acute lymphoblastic leukemia, multiple myeloma, or non-Hodgkin B-cell lymphoma.

Trial overview

This study is investigating LUMC-BOB1-B7-TCR.1 in patients with relapsed or refractory B-cell malignancies, which means B-cell cancers that came back after treatment or did not respond well to treatment.[1]

The trial includes people with B-cell acute lymphoblastic leukemia, multiple myeloma, and non-Hodgkin B-cell lymphoma.[1]

The main goal is to learn whether the treatment can be made and given as planned, and whether it is safe and may help patients respond.[1]

Who can join the study

The study is for patients who are HLA-B*07:02 positive.[1]

HLA-B*07:02 is a specific marker on cells, and the trial only includes people with this marker.[1]

People in the study must also have one of the target B-cell cancers listed in the trial record.[1]

What the researchers are measuring

In Phase 1, researchers are checking whether a drug product can be manufactured at the intended dose and whether included patients actually receive treatment.[1]

They are also measuring dose-limiting toxicities, which are side effects serious enough to limit further dose increases, during the 28 days after infusion.[1]

Another Phase 1 goal is to find the maximum tolerated dose, meaning the highest dose that still has acceptable safety, and then choose a recommended dose for Phase 2.[1]

In Phase 2, the study measures safety and toxicity by looking at serious and other adverse events for up to 2 years after infusion, using ASTCT and CTCAE reporting standards.[1]

The trial also measures response rate at 12 weeks after infusion, with response defined as absence of circulating B cells and/or the best objective response described in the literature.[1]

Trial phase and study design

This is an interventional study, which means the researchers assign a treatment and then watch what happens.[1]

The trial is a Phase 1/2 study, so it combines early dose-finding work with a later look at safety and response.[1]

The phase 1 dose work uses a Bayesian Dose Interval (BOIN) design, a method that helps researchers adjust dose levels based on observed toxicity rates.[1]

The target toxicity rate in this design is 0.3, which means the study is trying to find a dose level with an acceptable level of serious side effects.[1]

Trial status and size

The trial is currently Authorised.[1]

The planned enrollment is 22 patients.[1]

The intervention is given by intravenous administration, which means through a vein.[1]

Glossary

  • B-cell malignancies: Cancers that start in B cells, which are a type of white blood cell.
  • Relapsed: A cancer that came back after treatment.
  • Refractory: A cancer that did not respond well to treatment.
  • HLA-B*07:02: A specific marker on cells. The trial is limited to patients who have this marker.
  • Phase 1: The first study stage, usually focused on making sure the treatment can be given and on finding a safe dose.
  • Phase 2: A later study stage that looks more closely at safety and whether the treatment helps.
  • Dose-limiting toxicities (DLTs): Side effects that are serious enough to limit how much treatment can be given.
  • Maximum tolerated dose: The highest dose that patients can take with acceptable safety.
  • Recommended dose: The dose chosen for later study because it appears suitable based on early results.
  • Response rate: The number or percent of patients whose cancer improves or disappears after treatment.
  • Infusion: Treatment given through a vein.
