Chronic Kidney DiseasePhase 2NCT02224820
Phase II Study, Evaluation of Safety and Efficacy of IdeS in Chronic Kidney Disease
A Phase 2 study testing IdeS in people with Chronic Kidney Disease, run by Hansa Biopharma AB at 1 site in Sweden.
Trial summary
IdeS is an immunoglobulin g (IgG) cleaving enzyme. It will given to patients with donor specific antibodies to reduce the antibody load and thus enable kidney transplantation. IdeS antibody reducing efficacy and its safety will be studied. Read more about this study

- Adult, Older adult
Who may be able to join
- Diagnosed with chronic kidney disease and in dialysis with identified antibodies against at least two HLA antigens of which at least one is 3000 MFI or more as measured by SAB assay on at least two occasions.
Who cannot join

About this study
Official title: A Phase II Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Efficacy of Intravenous IdeS After Administration of Ascending Doses in Chronic Kidney Disease Patients
IdeS is an immunoglobulin g (IgG) cleaving enzyme. It will given to patients with donor specific antibodies to reduce the antibody load and thus enable kidney transplantation. IdeS antibody reducing efficacy and its safety will be studied.
Read the detailed description
Study 13-HMedIdeS-02 (EudraCT no. 2013-005417-13) is a single centre, single arm, dose finding, Phase II study in sensitized CKD patients assessing safety, tolerability, pharmacokinetics (PK) and efficacy of HMED-IdeS without intent to transplantation. However, patients are not removed from the transplant waitlist during the study. Included patients has a panel reactive antibody [PRA] >70% (n=7).

IdeSBiological
Doses are administered in ascending doses
| Study group | Role | What they receive |
|---|---|---|
| Intravenous IdeS | Experimental | One or two doses of IdeS in ascending doses Receives: Biological: IdeS |
What is being measured
The primary outcome is the main question the study is designed to answer.
Efficacy
Efficacy was defined as the IdeS dosing scheme in the majority of the patients resulting in human leucocyte antigen (HLA) antibody levels which are acceptable for transplantation, measured as mean fluorescent intensity (MFI) of less than 1100, within 24 hours from dosing. MFI was determined by single antigen bead (SAB) assay and detection of complement fixating ability (CIq Screen) in serum.
Measured: 24 hours
Secondary outcomes (4)
Safety
Adverse events (all clinical laboratory tests, vital signs and ECG jugded as clinically significant were reported as AEs)
Measured: 9 weeks
Pharmacodynamics
IgG cleavage and regeneration measured by ELISA
Measured: Up to day 64
Immunogenicity
Presence of Anti-Drug Antibodies formation in serum throughout a 64 day period
Measured: Up to 64 days
Pharmacokinetics
IdeS T1/2 in alpha phase. One patient who interrupted dose was excluded.
Measured: Up to 21 days

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing IdeS in people with Chronic Kidney Disease, run by Hansa Biopharma AB at 1 site in Sweden.
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 1 inclusion and 8 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 3 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Sweden. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 23 May 2016). 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?
Efficacy (time frame: 24 hours). 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 NCT02224820, which also lists 3 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 3 Mar 2017.
