Hyaluronidase (Human Recombinant)

Clinical trials of Hyaluronidase (Human Recombinant) are studying subcutaneous treatment approaches in people with primary immunodeficiency diseases and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). These trials mainly look at safety, tolerability, and how the treatment behaves in the body, including pharmacokinetics. The studies include adults and older adolescents in different trial phases.

Overview of the trial program

The clinical trial data for Hyaluronidase (Human Recombinant) focus on studies of subcutaneous treatment, which means treatment given under the skin.[1] The main trial settings in the source data are primary immunodeficiency diseases and chronic inflammatory demyelinating polyradiculoneuropathy, also called CIDP.[1][2][3]

Most of the listed studies are designed to compare TAK-881 with HyQvia, and they look at how the treatment behaves in the body, as well as safety and tolerability.[2][3] One additional Phase 1 trial in the source data is about subcutaneous durvalumab and is not a Hyaluronidase (Human Recombinant) study.[4]

Trials in primary immunodeficiency diseases

Two trials in the source data are for people with Primary Immunodeficiency Diseases (PIDD), a group of conditions where the immune system does not work properly.[1][2] These studies include a Phase 3 long-term safety study and a Phase 4 crossover study that compares treatments in older adolescents and adults.[1][2]

NCT06076642 is a Phase 3 study with 37 enrolled participants and the status listed as Authorised.[1] Its goal is to evaluate long-term safety and tolerability of TAK-881, with primary outcomes that include treatment-emergent adverse events and infusion withdrawals, interruptions, and rate reductions linked to TAK-881-related adverse events.[1]

NCT05755035 is a multicenter, prospective, open-label, randomized, crossover Phase 4 study with 50 enrolled participants and a Completed status.[2] It aims to show pharmacokinetic comparability between TAK-881 and HyQvia at steady-state after subcutaneous administration in subjects aged 16 years and older with PIDD.[2]

In simple terms, this means the researchers are checking whether the two treatments give similar blood exposure over time in the study group.[2] The main endpoint is AUC0-τ,ss based on total IgG levels, which is a way to measure total exposure during a dosing interval at steady-state.[2]

Trials in CIDP

One Phase 3 study in the source data targets adults with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), a long-lasting nerve disorder that can affect strength and movement.[3] This study is listed as Authorised and includes 65 participants.[3]

The study is a single-arm, multiple-dose, pharmacokinetic comparability trial between TAK-881 and HyQvia in adults with CIDP.[3] Its brief summary says the purpose is to show pharmacokinetic comparability after subcutaneous administration in participants with CIDP.[3]

The primary outcome is baseline-uncorrected area under the curve during the dosing interval at steady-state, based on total IgG levels.[3] This tells researchers how much treatment exposure the body has over the dosing period.[3]

What the trials measure

The listed trials measure both safety and pharmacokinetics (PK), which means how the treatment moves through the body.[1][2][3]

  • Treatment-emergent adverse events (TEAEs): unwanted medical events that happen after treatment starts.[1]

  • Infusion withdrawals, interruptions, and rate reductions: these show whether the infusion had to be stopped, paused, or slowed because of treatment-related problems.[1]

  • AUC0-τ,ss: a measure of total drug exposure over one dosing interval at steady-state.[2][3]

  • Total IgG levels: the studies use this blood marker to compare exposure between treatments.[2][3]

Study design and phases

The source data includes Phase 3, Phase 4, and Phase 1 studies, but only the Phase 3 and Phase 4 studies are directly about Hyaluronidase (Human Recombinant) in the provided records.[1][2][3][4]

The PIDD Phase 4 study is described as multicenter, prospective, open-label, randomized, and crossover.[2] These words mean the study was done at more than one center, followed participants forward in time, did not hide the assigned treatment, randomly assigned treatment order, and had participants receive more than one study treatment in sequence.[2]

The CIDP study is single-arm and multiple-dose, which means there is no separate comparison group in the source description and participants receive more than one dose during the study.[3]

What patients should know from the trial data

From the available trial records, Hyaluronidase (Human Recombinant) research is centered on people with immune-related and nerve-related conditions, especially PIDD and CIDP.[1][2][3]

The main research questions are whether the study treatments are safe, whether they are tolerated over time, and whether they produce similar exposure in the body when compared with HyQvia.[1][2][3]

The source data does not give detailed results, so the article can only describe the study goals, populations, phases, and outcomes that were planned or measured.[1][2][3]

Glossary

  • Primary Immunodeficiency Diseases (PIDD): A group of conditions where the immune system does not work properly and may not fight infections well.
  • Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP): A long-lasting nerve disorder that can cause weakness, numbness, and trouble with movement.
  • Phase 1: An early trial phase that usually focuses on safety and how the treatment behaves in the body.
  • Phase 3: A later trial phase that often includes more people and checks safety and effectiveness in a larger group.
  • Phase 4: A study phase done after a treatment is already in use, often to learn more about safety and performance.
  • Pharmacokinetics (PK): How a treatment is absorbed, moved, and removed by the body.
  • Steady-state: A point when the amount of treatment in the body stays fairly stable with repeated dosing.
  • AUC0-τ,ss: A measure of total drug exposure during one dosing interval at steady-state.
  • Total IgG: The total amount of a type of antibody measured in the blood.
  • TEAEs: Treatment-emergent adverse events, meaning unwanted medical events that happen during the study after treatment starts.
  • Infusion withdrawal: Stopping an infusion before it is finished.
  • Open-label: A study where both the researchers and participants know which treatment is being given.
