About this study

Official title: An Open-Label Multi-Center Study of Eculizumab in Children and Adolescents With a Diagnosis of Paroxysmal Nocturnal Hemoglobinuria

The primary objective of this study was to evaluate the pharmacokinetic (PK) and pharmacodynamic (PD) parameter estimates of eculizumab to confirm the dose regimens for pediatric and adolescent participants with PNH.

Read the detailed description

This was an open-label, multi-center study of eculizumab administered to approximately 6 to 8 pediatric and adolescent participants aged 2 to 17 years with PNH. There were 3 periods in this study (screening, treatment, and post-treatment) with the treatment period having 2 dosing phases (induction and maintenance). If all screening criteria were met, the participant was eligible to enter the treatment period of the study after receiving Neisseria meningitidis (N. men), Streptococcus pneumoniae (S. pneumo), and Haemophilus influenzae (H. influ) vaccinations at least 14 days prior to first dose of study drug, or was vaccinated and received treatment with appropriate antibiotics until 14 days after the vaccinations. Participants received eculizumab intravenously (IV) based on their weight. Eculizumab was administered via an IV infusion at a rate of 5 to 10 milliliters (mL) per kilogram (kg) per hour (hr) (mL/kg/hr) for at least 25 minutes. The planned duration of treatment was 12 weeks with a 4-week induction phase and an 8-week maintenance phase. At the Investigator's and parents/legal guardian's discretion, participants who completed this study with eculizumab could continue treatment with commercially available eculizumab (Soliris®) and were followed in the Soliris® PNH Registry. Participants who stopped study participation before study completion or who did not continue with Soliris® treatment at the completion of the study were followed for 8 weeks and monitored for signs and symptoms of serious hemolysis.

What is being measured

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

  1. Peak And Trough Concentrations Of Eculizumab In Serum At Week 12

    Serum concentrations of eculizumab were measured by using a validated enzyme-linked immunosorbent assay (ELISA) method developed at Alexion Pharmaceuticals Bioanalytical Laboratory. The range of the analytical assay was 10 to 600 microgram per milliliter (μg/mL). Peak concentrations were not measured at the early termination (ET) visit.

    Measured: Pre-infusion and 1 hour post-infusion at End of Treatment (EOT) (Day 84 [Week 12]) or ET

Secondary outcomes (4)
  1. Number Of Participants With Treatment-emergent Adverse Events (TEAEs)

    A TEAE was defined as any adverse event (AE) not present prior to exposure to eculizumab or any event already present that worsened in either intensity or frequency following exposure to eculizumab. A serious TEAE was defined as any event that resulted in death, was immediately life threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, or was a congenital anomaly/birth defect. Related TEAEs were considered by investigators to be definitely, probably, or possibly related to administration of the study drug. Relationship is ordered as follows: unrelated, possibly related, probably related, or definitely related. TEAEs and TEAE severity were classified in accordance with the Medical Dictionary for Regulatory Activities (MedDRA) 13.0 dictionary. A summary of serious and all other non-serious AEs regardless of causality is located in the Reported Adverse Events module.

    Measured: First dose of study drug (Day 0) to End of Follow-up (Week 20 [8 weeks after EOT])

  2. Area Under The Curve (AUC) Of The Change From Baseline To Week 12 In Levels Of Lactate Dehydrogenase (LDH)

    The AUC of LDH was calculated by using the change of LDH from baseline values for each participant up to Week 12. For those participants with missing LDH values, the last observation carried forward method (LOCF) was used to impute missing values. Individual AUC values of LDH were summarized and tabulated.

    Measured: Baseline, EOT (Day 84 [Week 12]) or ET

  3. Concentration Of Plasma-free Hemoglobin At Baseline And Week 12

    Plasma-free hemoglobin was determined for each participant by using standard laboratory assays. The values of plasma-free hemoglobin were summarized by visit.

    Measured: Baseline, EOT (Day 84 [Week 12]) or ET

  4. Change From Baseline In LDH Levels

    Levels of LDH were determined by using standard laboratory assays. LDH values and the change of LDH from baseline were summarized by visit.

    Measured: Baseline, Weeks 1 to 12 or ET

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Eculizumab in people with Hemoglobinuria, Paroxysmal, run by Alexion Pharmaceuticals, Inc. at 3 sites 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 8 inclusion and 6 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 31 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. 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 31 Oct 2018). 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?

Peak And Trough Concentrations Of Eculizumab In Serum At Week 12 (time frame: Pre-infusion and 1 hour post-infusion at End of Treatment (EOT) (Day 84 [Week 12]) or ET). 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 NCT00867932, which also lists 1 linked publication.

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?
