AUTOLOGOUS CD34+ ENRICHED CELL FRACTION THAT CONTAINS CD34+ CELLS TRANSDUCED WITH RETROVIRAL VECTOR THAT ENCODES FOR THE HUMAN ADA CDNA SEQUENCE

Clinical trials are studying AUTOLOGOUS CD34+ ENRICHED CELL FRACTION THAT CONTAINS CD34+ CELLS TRANSDUCED WITH RETROVIRAL VECTOR THAT ENCODES FOR THE HUMAN ADA CDNA SEQUENCE in people with acute ischemic stroke. The trial is looking at whether this treatment can affect infarct size and is focused on safety and early signs of benefit in a phase 2 study.

Trial overview

The available study is titled StroKE34 Study Protocol and it is a randomized controlled Phase IIa trial of intra-arterial CD34+ cells in acute ischemic stroke.[1] The trial is authorised and studies people with ischemic stroke.[1]

The intervention listed in the trial data is AUTOLOGOUS CD34+ ENRICHED CELL FRACTION THAT CONTAINS CD34+ CELLS TRANSDUCED WITH RETROVIRAL VECTOR THAT ENCODES FOR THE HUMAN ADA CDNA SEQUENCE, shown in the source as Strimvelis 1-10 x 10^6 cells/mL dispersion for infusion.[1] The trial brief summary says the study is evaluating the effect of CD34+ cells given intra-arterially on infarct volume after stroke.[1]

Who is being studied

The target population is people with acute ischemic stroke.[1] The brief summary says the study includes patients in an early subacute stage, about 7 days after stroke, or a later subacute stage, about 20 days after stroke.[1]

This means the trial is not for all stroke patients, but for a specific time window after the stroke event.[1] In simple terms, the researchers are studying whether treatment soon after stroke may help limit the later size of the brain injury.[1]

Study design and phase

This is an interventional study, which means the research team gives a treatment and then measures what happens.[1] It is also described as a randomized controlled trial, meaning participants are assigned by chance and compared in a controlled way.[1]

The study phase is Phase 2.[1] Phase 2 trials usually look for early signs that a treatment may work, while also continuing to follow safety and study design questions.[1]

The intervention is described as being given intra-arterially, which means into an artery, a blood vessel that carries blood away from the heart.[1] The trial data also lists an intravenous infusion form in the intervention field, but the brief summary specifically says the cells are administered intra-arterially.[1]

What the trial measures

The main outcome is infarct volume at three months after ischemic stroke.[1] Infarct volume means the size of the damaged area in the brain after the stroke.[1]

This outcome helps researchers see whether the treatment may reduce the amount of brain injury over time.[1] The trial data does not list additional outcomes, so the main focus in the available source is the three-month infarct volume.[1]

Trial status and size

The study status is Authorised.[1] The planned enrollment is 30 participants, which makes this a small clinical study.[1]

Because the trial is small and in Phase 2, it is designed to give early information about whether the approach should be studied further in stroke care.[1]

Ordliste

  • Acute ischemic stroke: A stroke caused by a blocked blood vessel in the brain. This can reduce blood flow and damage brain tissue.
  • Subacute stage: The period after the very first phase of illness, when the body is still in early recovery. In this trial, it means about 7 days or 20 days after stroke.
  • Phase 2: A clinical trial phase that looks at whether a treatment may help and continues to monitor safety.
  • Randomized: Participants are assigned by chance to a study group. This helps make the results more fair.
  • Controlled trial: A study design that compares one treatment with another group or standard care.
  • Interventional study: A study in which researchers give a treatment or procedure and then measure what happens.
  • Intra-arterial: Given into an artery, which is a blood vessel that carries blood away from the heart.
  • Intravenous infusion: Treatment given through a vein, usually by a drip.
  • Infarct volume: The size of the damaged area caused by a stroke.
  • Enrollment: The number of people planned for a study or actually included in it.
