IMMUNOSTEM

Clinical trials investigating IMMUNOSTEM are studying a first-in-human gene therapy approach for early type 1 diabetes. The trial is mainly designed to check safety, with a small group of patients taking part in a phase 1/2 study. It also looks at early signs of whether the treatment can be tested further.

Trial overview

The available clinical trial for IMMUNOSTEM is a first-in-human study in people with early type 1 diabetes.[1] It is an interventional trial, which means researchers are giving a treatment and then measuring what happens.[1]

The trial title says it is testing a gene therapy using the patient’s own stem cells to treat early type 1 diabetes.[1] The study brief summary says the main objective is to evaluate study treatment safety.[1]

Who is being studied

The condition being studied is type 1 diabetes, specifically early disease.[1] This means the trial is aimed at people who are in the early stage of this condition, not the general population.[1]

The planned enrollment is 15 patients, so this is a small early trial.[1] Small studies like this are common when a treatment is being tested for the first time in people.[1]

What the study tests

The intervention is described as autologous CD34+ HSPCs transduced ex vivo with a LVV encoding the hPD-L1 cDNA, given by intravenous use.[1] In simple words, the study uses the patient’s own stem cells, changes them in a laboratory, and gives them back through a vein.[1]

This article does not go beyond the trial data to explain how the treatment works, because the source information focuses on the study design and safety goals.[1]

Phase and study size

The trial is in phase 1/2.[1] Phase 1 studies usually look first at safety, while phase 2 studies look more closely at early signs of whether a treatment may be worth testing further.[1]

The study is authorised and has a planned enrollment of 15 patients.[1] This suggests an early development program with careful monitoring.[1]

Main outcomes and safety checks

The primary endpoint is safety.[1] The trial will measure the number and description of adverse events, which are unwanted medical problems that happen during the study.[1]

Safety will also be checked using vital signs, laboratory tests, and the frequency and severity of adverse events and serious adverse events.[1] Serious adverse events are more severe problems, such as those that are life-threatening or need hospital care.[1]

Safety will be assessed over the first 3, 12, and 24 months of follow-up in the pilot phase.[1] The data safety monitoring board, or DSMB, will review the pilot safety results at 3 months before the study can continue to the next stage.[1]

What the status means

The trial status is Authorised.[1] This means the study has been approved to move forward, but the source data do not show final results yet.[1]

Because this is an early trial, the main question is whether the treatment can be given safely to people with early type 1 diabetes.[1] The trial is not presented in the source as a completed study, so there are no outcome results to report yet.[1]

Glossary

  • Type 1 diabetes: A long-term disease in which the body does not make enough insulin. Insulin is the hormone that helps control blood sugar.
  • First-in-human: The first time a treatment is tested in people. This is an early step in clinical research.
  • Gene therapy: A treatment that uses genetic material to try to change how cells work.
  • Stem cells: Early cells that can develop into different types of cells in the body.
  • Autologous: Made from the patient’s own cells, not from another person.
  • CD34+ HSPCs: A type of blood-forming stem cell used in some advanced treatments. HSPCs means hematopoietic stem and progenitor cells, which are cells that can make blood cells.
  • Ex vivo: Done outside the body, in a laboratory, before the cells are given back to the patient.
  • LVV: Short for lentiviral vector. This is a tool used to carry genetic material into cells.
  • Adverse event: Any unwanted medical problem that happens during a study, whether or not it is caused by the treatment.
  • Serious adverse event: A more severe medical problem during a study, such as one that is life-threatening or needs hospital care.
  • DSMB: Short for Data Safety Monitoring Board. This is an independent group that reviews safety information during a trial.
  • Endpoint: A main result the researchers measure to see what happened in the trial.
