About this study

Official title: Evaluating the Safety of GAMMAGARD LIQUID for the Treatment of Patients With Chronic Inflammatory Demyelinating Polyradiculoneuropathy

The main aim of this study is to evaluate the rates of adverse events of special interest (AESIs) (thrombotic events, acute kidney injury [AKI], and hemolytic events) among participants with CIDP initiating GGL compared with rates among participants with CIDP initiating comparator intravenous immunoglobulin (IVIG) products.

No study medicines will be provided to participants in this study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT05363358
Study groupRoleWhat they receive
Ig-naive (New-to-class) CohortParticipants who initiate GGL or one of the comparator IVIG products who have no record of previous use of any Ig product (Ig naive) for at least 6 months before study initiation will be include in this cohort.
Ig-experienced (New-to-drug) CohortParticipants who initiate either GGL or a comparator IVIG product with no record of previous use of that specific IVIG product but with previous use of any other Ig product (Ig experienced) in all available study data will be included in this cohort.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Thrombotic Events (TEs)

    Thrombotic events will be reported as adverse events of special interest (AESI) and will include: acute ischemic stroke, acute myocardial infarction (AMI), and acute venous thromboembolism (VTE) events including (deep vein thrombosis (DVT), cerebral venous thrombosis (CVT), pulmonary embolism (PE).

    Measured: Throughout observational period, from 01 January 2008 to 31 December 2019 (Up to 12 years)

  2. Number of Participants With Acute kidney injury (AKI)

    AKI will be reported as AESI and will include acute renal failure.

    Measured: Throughout observational period, from 01 January 2008 to 31 December 2019 (Up to 12 years)

  3. Number of Participants With Hemolytic Events (HEs)

    HEs will be reported as AESI and will include nonautoimmune hemolytic anemia, acquired hemolytic anemia, ABO incompatibility reaction, or hemolytic transfusion reaction.

    Measured: Throughout observational period, from 01 January 2008 to 31 December 2019 (Up to 12 years)

Secondary outcomes (3)
  1. Number of Participants With Anaphylaxis

    Anaphylaxis will be reported as adverse event (AE) and will include anaphylactic reaction or anaphylactic shock.

    Measured: Throughout observational period, from 01 January 2008 to 31 December 2019 (Up to 12 years)

  2. Number of Participants With Transfusion-related Acute Lung Injury (TRALI)

    Number of participants with TRALI will be reported.

    Measured: Throughout observational period, from 01 January 2008 to 31 December 2019 (Up to 12 years)

  3. Number of Participants With Transfusion-associated Circulatory Overload (TACO)

    Number of participants with TACO will be reported.

    Measured: Throughout observational period, from 01 January 2008 to 31 December 2019 (Up to 12 years)

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP), run by Takeda at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Thrombotic Events (TEs) (time frame: Throughout observational period, from 01 January 2008 to 31 December 2019 (Up to 12 years)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
