A Safety Study of Tocilizumab to Improve Transplant Rates in Highly Sensitized Patients Awaiting Kidney Transplantation

NCT ID: NCT01594424

Last Updated: 2016-08-25

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1/PHASE2
• Total Enrollment: 10 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2012-06-30
• Study Completion Date: 2015-05-31

Brief Summary

In this Phase I/II trial, 10 highly sensitized patients will be entered after informed consent and will receive Intravenous Immunoglobulin (IVIG) at 2 gm/kg + Tocilizumab 8 mg/kg x 5 doses on days 15, 45, 75, 105, 119, 135, and 149. If robust reductions in anti-HLA antibody are seen, patients will progress to kidney transplantation when an "acceptable" crossmatch is achieved with a living donor (LD) or deceased donor (DD). Those receiving transplants will also receive Tocilizumab infusion monthly X7 doses post-transplant. All subjects will have intensive monitoring of Donor Specific Antibodies (DSA), viral PCRs, and routine post-transplant labs. At 6 months post-transplant, those who have retained their transplanted kidney will have a protocol biopsy.

Eligibility Criteria

Inclusion Criteria

• Subject/Parent/Guardian must be able to understand and provide informed consent.

Exclusion Criteria

• Major surgery (including joint surgery) within 8 weeks prior to screening or planned major surgery within 6 months following randomization.
• Treatment with any investigational agent within 4 weeks (or 5 half-lives of the investigational drug, whichever is longer) of screening.
• Previous treatment with any cell-depleting therapies, including investigational agents or approved therapies, some examples are CAMPATH, anti-CD4, anti-CD5, anti¬CD3, anti-CD19 and anti-CD20 within 6 months of baseline.
• Treatment with intravenous gamma globulin, plasmapheresis or Prosorba column within 6 months of baseline
• Immunization with a live/attenuated vaccine within 2 months prior to baseline.
• Previous treatment with TCZ (an exception to this criterion may be granted for single dose exposure upon application to the sponsor on a case-by-case basis).
• Any previous treatment with alkylating agents such as chlorambucil, (within 1 year) or with total lymphoid irradiation.

Exclusions for General Safety:

• History of severe allergic or anaphylactic reactions to human, humanized or murine monoclonal antibodies.
• Evidence of serious uncontrolled concomitant cardiovascular, nervous system, pulmonary (including obstructive pulmonary disease), hepatic, endocrine (include uncontrolled diabetes mellitus) or gastrointestinal disease (including complicated diverticulitis, ulcerative colitis, or Crohn's disease.)
• Current liver disease as determined by principal investigator unless related to primary disease under investigation
• Known active current or history of recurrent bacterial, viral, fungal, mycobacterial or other infections (including but not limited to tuberculosis and atypical mycobacterial disease, Hepatitis B and C, and herpes zoster, but excluding fungal infections of nail beds). These are limited to non-access related infections.
• Any major episode of infection requiring hospitalization or treatment with IV antibiotics within 4 weeks of screening or oral antibiotics within 2 weeks prior to screening.
• Active TB requiring treatment within the previous 3 years. Patients should be screened for latent TB and, if positive, treated following local practice guidelines prior to initiating TCZ. Patients treated for tuberculosis with no recurrence in 3 years are permitted.
• Primary or secondary immunodeficiency (history of or currently active) unless related to primary disease under investigation.
• Evidence of active malignant disease, malignancies diagnosed within the previous 10 years (including hematological malignancies and solid tumors, except basal and squamous cell carcinoma of the skin or carcinoma in situ of the cervix uteri that has been excised and cured), or breast cancer diagnosed within the previous 20 years unless related to primary disease under investigation.
• Pregnant women or nursing (breast feeding) mothers.
• Patients with reproductive potential not willing to use an effective method of contraception.
• History of alcohol, drug or chemical abuse within 1 year prior to screening.
• Neuropathies or other conditions that might interfere with pain evaluation unless related to primary disease under investigation.
• Patients with lack of peripheral venous access.
• Body weight of > 150 kg.

• Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 1.5 times upper limit of normal (ULN)
