Observational Study of Elizaria® in aHUS Patients

Completed
Conditions
aHUS
Atypical Hemolytic Uremic Syndrome
Interventions
Drug: Elizaria®
Registration Number
NCT04749810
Lead Sponsor
AO GENERIUM
Brief Summary

It is a multicenter observational non-comparative study of the efficacy and safety of long-term pathogenetic Elizaria® therapy in patients with atypical Hemolytic Uremic Syndrome

Detailed Description

After screening, patients meeting all of the inclusion / non-inclusion criteria and vaccinated against meningococcal infections were treated by Elizaria®.

The study is planned to include at least 50 patients receiving Elizaria® for the aHUS treatment.

The study will consist of a screening period of up to 4 weeks, including, if necessary, immunization with meningococcal vaccine, a treatment period of 52 weeks.

Medication will be prescribed in accordance with routine medical practice. Accordingly to minimize the risks and subjectivity of assessments the methods adopted in the routine practice of treating patients with aHUS will be used.

Investigators enroll patients with aHUS diagnosis who have indications for pathogenetic therapy and who are receiving Elizaria® under the government program. Patients will receive medication in accordance with the established requirements of national standards and protocols for the treatment of patients with aHUS. The registration of the amount of the drug used will be carried out on the basis of information in the Patient Diaries, as well as primary documentation.

Primary Outcome Measures
NameTimeMethod
Change in platelet count compared to the screening level52 week

Change in platelet count at 52 week after treatment with study drug compared to baseline at screening

Secondary Outcome Measures
NameTimeMethod
Dynamics of membrane attack complex (MAC) level compared to baseline at Visit 252 week

Changes in MAC levels at 52 week compared to baseline

Proportion of patients with normalized platelet levels52 week

Proportion of patients with normal platelet count at 52 week after initiation of study drug treatment

Proportion of TMA-related interventions52 week

The proportion of TMA-related interventions is defined as (number of plasma therapy sessions + number of hemodialysis sessions) / number of patient days.

Proportion of patients with an improvement in glomerular filtration rate (eGFR) of 15 ml / min / 1.73m2 or more compared to the baseline level at screening.52 week

Proportion of patients with improvement in eGFR of 15 ml/min/1.73m2 or more at 52 week after treatment with study drug compared to baseline at screening

The frequency and severity of adverse events (AEs)52 weeks

Frequency and severity of adverse events (AEs), including serious adverse events (SAEs) and AEs associated with study drug use

Proportion of patients with antidrug antibodies52 weeks

Proportion of patients with antidrug antibodies; titer of antidrug antibodies and their neutralizing activity

Proportion of patients with more then 1 stage-improvement in chronic kidney desease (CKD) compared to baseline at screening.52 week

Proportion of patients with \>=1 stage improvement in CKD at 52 week after initiation of study drug treatment compared with baseline at screening

Proportion of patients with no thrombotic microangiopathy (TMA) events52 week

The absence of TMA-related events is defined as the absence, for at least 12 weeks, of: 1) a decrease in platelet counts greater than 25% from baseline at screening; 2) plasma therapy; 3) hemodialysis.

Change in lactate dehydrogenase (LDH) levels from baseline at screening52 week

Change in LDH levels at 52 week after starting study drug treatment from baseline at screening

Change in eGFR (ml / min. / 1.73m2) compared with the baseline level at screening;52 week

Change in eGFR (mL/min/1.73m2) at 52 week after initiation of study drug treatment from baseline at screening

Proportion of patients with complete TMA response52 week

Complete TMA response is defined as the absence of abnormalities in LDH and platelet levels + improvement in renal function (decrease in creatinine levels by 25% or more compared to the baseline value on screening) when performed at least two consecutive tests within 8 weeks

Proportion of patients with an increase in hemoglobin level of more than 20 g / l compared to the baseline level at screening.52 week

Proportion of patients with an increase in hemoglobin level of more than 20 g/l at 52 week after the start of study drug treatment compared with baseline at screening
