Details and patient eligibility

About

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.

Full 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).

Inclusion criteria

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.

Exclusion criteria

Prior malignancy within 2 years excluding adequately treated basal cell or squamous cell skin cancer, cervical carcinoma in situ and prostate cancer Gleason <6 and prostate-specific antigen (PSA) <10 ng/mL.
Any positive result on screening for serum hepatitis B surface antigen, hepatitis C antibody and human immunodeficiency virus (HIV
Clinical signs of ongoing infectious disease.
Severe other conditions requiring treatment and close monitoring, e.g. cardiac failure > New York Heart Association (NYHA) grade 3, unstable coronary disease or oxygen dependent chronic obstructive pulmonary disease (COPD)
History of any other clinically significant disease or disorder which, in the opinion of the investigator, may either put the patient at increased risk because of participation in the study, or influence the results or the patient's ability to participate in the study
Hypogammaglobulinemia defined as any values of P-total IgG less than 3 g/L
History of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity, as judged by the investigator or history of hypersensitivity to drugs with a similar chemical structure or class to IdeS (e. g streptokinase and/or staphylokinase)
Has received another new chemical entity (defined as a compound which has not been approved for marketing) or has participated in any other clinical study that included drug treatment within 4 months of the first administration of investigational product in this study. Patients consented and screened but not dosed in previous studies are not excluded
