About this study

Official title: An Open-label Multicenter Study to Evaluate the Safety and Tolerability of Higher Infusion Parameters of Immune Globulin Subcutaneous (Human), 20% Liquid (Hizentra®) in Subjects With Primary Immunodeficiency

This multicenter, open-label, parallel-arm, non-randomized study is designed to evaluate safety and tolerability of higher infusion parameters of IgPro20 in subjects with primary immunodeficiency (PID). A total of 45 subjects (including at least 14 [30%] pediatric subjects ≤ 17 years of age and at least 9 [20%] obese subjects with body mass index [BMI] of ≥30 kg/m2) with confirmed PID will be evaluated in the study. The study will include three cohorts of 15 subjects each as follows: i) Pump-Assisted Volume Cohort (weekly infusions), volume per injection site of 25 mL up to 50 mL, ii) Pump Assisted Flow Rate Cohort (weekly infusions), flow rate per injection site of 25 mL/hour up to 100 mL/hour, iii) Manual Push Flow Rate Cohort (2 to 7 infusions per week), flow rate per injection site of 25 to 30 mL/hour up to 120 mL/hour (equivalent of approximately 0.5 mL/minute up to 2 mL/minute). Each cohort will test 3 infusion parameter levels (4 for the pump-assisted flow rate cohort), repeated at least 4 times over a duration of 12 weeks (16 weeks for the flow rate cohort). After 4 infusion weeks at each level, qualifying subjects (responders) will switch to the next infusion parameter level (eg, from 25 to 50 mL/h). During the study, the weekly dose will remain unchanged (as prescribed by treating physician, usually within 100-200 mg/kg per week range); only the respective infusion parameter under evaluation will change.

What is being measured

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

  1. Percentage of Responders

    A responder is a subject within the Pump-Assisted Cohorts that performs at least 3 out of 4 valid infusions at a certain infusion parameter level (weekly volumes per injection site of 25-50 mL; weekly flow rates per injection site of 25-100 mL/hour). Determination of a responder in the Manual Push Cohort is more complex due to the expected variable frequency of infusions per week (ie, 5-17) for different subjects. A responder within the Manual Push Cohort is a subject that performs a minimum number of valid infusions during 4 weeks corresponding to a certain flow rate level ([ie, 2-7 times per week], flow rates per injection site of 30-120 mL/hour). Valid infusions do not need to be consecutive, but each subject needs to adhere to the same schedule (number of infusions per week) throughout the study. An infusion parameter will be considered successful if at least one third (≥ 33%) of the subjects in the corresponding cohort are responders at that infusion parameter level.

    Measured: At the end of 4 weeks for each planned infusion parameter

Secondary outcomes (6)
  1. Rate of Treatment-emergent Adverse Events (TEAEs) Per Infusion

    Adverse event rate per infusion = number of adverse events/total number of infusions prior to subject's start date of non-response. Only events are included which start prior to subject's start date of non-response.

    Measured: At the end of 4 weeks for each planned infusion parameter

  2. Rate of Local TEAEs Per Infusion

    Local adverse event rate per infusion = number of local adverse events/total number of infusions prior to subject's start date of non-response. Local Adverse Events: comprises all events reported within the MedDRA high level terms "administration site reactions NEC (Not Elsewhere Classified)", "infusion site reactions", and "injection site reactions". Only events are included which start prior to subject's start date of non-response.

    Measured: At the end of 4 weeks for each planned infusion parameter

  3. Time to Onset of Local TEAEs

    Local Adverse Events: comprises all events reported within the MedDRA high level terms "administration site reactions NEC", "infusion site reactions", and "injection site reactions". Only events are included which start prior to subject's start date of non-response.

    Measured: At the end of 4 weeks for each planned infusion parameter

  4. Intensity of Local TEAEs

    Mild = A type of AE that is usually transient and may require only minimal treatment or therapeutic intervention. The event does not generally interfere with usual activities of daily living. Moderate = A type of AE that is usually alleviated with additional specific therapeutic intervention. The event interferes with usual activities of daily living, causing discomfort but poses no significant or permanent risk of harm to the subject. Severe = A type of AE that interrupts usual activities of daily living, or significantly affects clinical status, or may require intensive therapeutic intervention. Only events are included which start prior to subject's start date of non-response.

    Measured: At the end of 4 weeks for each planned infusion parameter

  5. Duration of Local TEAEs

    Local Adverse Events: comprises all events reported within the MedDRA high level terms "administration site reactions NEC", "infusion site reactions", and "injection site reactions".

    Measured: At the end of 4 weeks for each planned infusion parameter

  6. Tolerability of Infusions

    Tolerability = number of infusions without severe local adverse events / total number of infusions. Severe = A type of AE that interrupts usual activities of daily living, or significantly affects clinical status, or may require intensive therapeutic intervention. Only events are included which start prior to subject's start date of non-response.

    Measured: At the end of 4 weeks for each planned infusion parameter

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing IgPro20 in people with Primary Immunodeficiency, run by CSL Behring at 12 sites in 2 countries.

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 11 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 Jan 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percentage of Responders (time frame: At the end of 4 weeks for each planned infusion parameter). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03033745, which also lists 2 linked publications.

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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Mar 2020.
