Treatment of Lupus Nephritis With Allogeneic Mesenchymal Stem Cells

Официальное название

Phase II, Double-Blind, Placebo-Controlled Clinical Trial to Evaluate Safety and Efficacy of Mesenchymal Stem Cells (MSV-allo) in the Treatment of Lupus Nephritis

Обзор

The purpose of this study is to evaluate the safety and efficacy of mesenchymal stem cells (MSCs) obtained from bone marrow for the treatment of adults with active proliferative lupus nephritis. The objective of this study is to evaluate the efficacy of mesenchymal stem cells (MSCs) in achieving a full or partial response in the treatment of Lupus Nephritis (LN) during its induction period.

Подробное описание

A Phase 2b, double-blind (neither the participant nor the investigator will know if active drug or placebo is assigned), placebo-controlled, randomized (assigned by chance), in which subjects with Lupus Nephritis (LN), who do not respond -or respond partially- to induction treatment, shall receive either MSCs (2 million cells/Kg) or placebo by intravenous injection. The administration of cells will be done only once.

Вмешательства

• Препарат Mesenchymal stem cells (MSC)
  Endovenous injection of MSV in saline solution

Критерии исключения

A - Related to previous treatments:

• Use of corticosteroids or mycophenolate above the doses allowed for induction, according to the Consensus Document of the Systemic Autoimmune Diseases Group of the Spanish Society of Internal Medicine and the Spanish Society of Nephrology.
• Use of rituximab, belimumab, ocrelizumab or other biologic therapies against B cells in the 6 months prior to selection.
• Use of cyclophosphamide in the 6 months prior to selection.
• Use of any tumor necrosis factor inhibitor treatment in the 6 months prior to selection.
• Use of immunoglobulins in the 6 months prior to selection.
• Change in doses of an angiotensin converting enzyme inhibitor or an angiotensin receptor inhibitor in the two months prior to selection.
• Treatment with another investigational medicinal product within three months prior to selection or 5 times the half-life of the agent.

B - Related to medical problems:

• Any pathology, including an uncontrolled disease other than SLE, which, in the opinion of the investigator, the sponsor or the person they designate, constitutes an inappropriate risk or a contraindication for participation in the trial or that could interfere with the objectives of the trial, its performance or evaluation.
• Cardiac, peripheral, or cerebrovascular cardiovascular events in the 6 months prior to the selection visit.
• Active cardiac arrhythmia or clinically significant electrocardiogram abnormalities at selection visit or on the day of randomization that, in the opinion of the investigator, sponsor, or designee, constitute an inappropriate risk or contraindication to participation in the study.
• Thromboembolic events in the 12 months prior to or during selection, whether or not associated with associated antiphospholipid syndrome, or inadequate anticoagulation tests 6 weeks immediately prior to or during selection visit.
• Active central nervous system SLE that is considered severe or progressive (recent uncontrolled seizures, changes in anticonvulsant treatment within 3 months prior to selection visit, or resulting in significant cognitive impairment).
• History or current diagnosis of a demyelinating disease such as multiple sclerosis or optic neuritis.
• Comorbidities that require treatment with systemic corticosteroids (oral, rectal or injectable) such as asthma or inflammatory bowel disease.
• Antecedents or plans for an organ transplant.
• Clinically significant active viral, bacterial or fungal infection, or having suffered a major episode of infection that required hospitalization or parenteral treatment in the 4 weeks prior to the selection visit, during the selection visit, or having finished anti-infective treatment within 2 weeks prior to or during selection, or a history of recurrent infections (three or more cases of the same type of infection in a consecutive 12-month period). Controlled vaginal candidiasis, onychomycosis, and genital or oral herpes simplex virus would not be reasons for exclusion.
• History of or positive human immunodeficiency virus (HIV) test result, hepatitis C antibodies and/or detection by polymerase chain reaction, hepatitis B surface antigen (HBsAg+), and/or IgM or total antibodies against hepatitis B nuclear antigen at selection.
• Diagnosis of active or latent tuberculosis (TB) using a purified protein derivative TB skin test (induration ≥ 5 mm) or a positive Quantiferon test result, at selection or within 3 months prior to the selection visit. Patients who have completed previous adequate treatment or who are receiving treatment will not repeat the test. Patients who are receiving adequate TB treatment for at least 4 continuous weeks prior to the selection visit and who are expected to complete the treatment regimen will not be excluded.
• Presence of class 3 or 4 uncontrolled congestive heart failure according to the New York Heart Association.
