Clinical Trial: Risk of Nephrogenic Systemic Fibrosis (NSF) in Patients With Moderate Renal Insufficiency After the Administration of Magnevist

Study Status: Completed
Recruit Status: Completed
Study Type: Observational

Official Title: Prospective Non-randomized Observational (Pharmacoepidemiologic) Cohort Study (Open-label, Multicenter) to Assess the Magnitude of Potential Risk With the Administration of Magnevist® Injection i

Brief Summary: Assess potential risk for NSF in subjects with renal impairment (moderate) post magnevist injection. Subjects will be screened within 48 hours of previously scheduled MRI, those meeting the enrollment criteria will be enrolled prior to MRI and followed for 2 years post MRI with visits occuring at 1yr and 2 yr timepoints, in addition follow-up phone calls conducted at 1, 3, 6 and 18 months to assess for skin changes suggestive of NSF.

Detailed Summary:
Sponsor: Bayer

Current Primary Outcome:

  • Number of Participants Who Developed Nephrogenic Systemic Fibrosis (NSF), Based on Diagnostically Specific Clinical and Histopathological Information-cohort Analysis and Full Analysis Set [ Time Frame: Up to 24 months following the administration of Magnevist ]
    Either clinical or histopathology score had to be at least 2 and the other at least 3 for diagnosis of NSF. Clinical score 2, 3 or 4 was derived from more than one minor criterion finding, one major criterion finding or more than one major criterion finding respectively. Major Criteria include patterned plaques, joint contractures, cobblestoning and marked induration/Peau d'orange (upper extremity or above knee); minor Criteria include puckering/linear banding, superficial (plaque/patch), dermal papules and scleral plaques (subject aged <45 years). Pathology score 2, 3 or 4 was derived from 2, 3 or at least 4 histological criteria findings respectively. Histological Criteria include increased cellularity (spindled and/or epithelioid) with few other inflammatory cells, CD34+ spindle or epithelioid cells in a reticular or parallel arrangement with "tram-tracking," presence of both fine collagen and ropey collagen surrounded by clefts, elastic fibers preserved and septal involvement.
  • Number of Participants Who Developed NSF, Based on Diagnostically Specific Clinical and Histopathological Information-full Analysis Set [ Time Frame: Up to 24 months following the administration of Magnevist ]
    Either clinical or histopathology score had to be at least 2 and the other at least 3 for diagnosis of NSF. Clinical score 2, 3 or 4 was derived from more than one minor criterion finding, one major criterion finding or more than one major criterion finding respectively.

    Original Primary Outcome: Number of subjects with onset of biopsy confirmed NSF or cutaneous skin changes consistent with NSF following the administration of Magnevist within the 2 year follow-up period [ Time Frame: 2 years ]

    Current Secondary Outcome:

    • Total Number of Participants With Clinicopathological Correlation of 'NSF' or 'Consistent With NSF' and Subjects Without Biopsy Developing Clinical Signs Consistent With NSF-cohort Analysis and Full Analysis Set [ Time Frame: Up to 24 months following the administration of Magnevist ]
      Either clinical or histopathology score need at least 2 and the other at least 3 for diagnosis of NSF. Clinical score 2, 3 or 4 required more than 1 minor criterion, 1 major criterion or more than 1 major criterion respectively. Major criteria: patterned plaques, joint contractures, cobblestoning, marked induration/Peau d'orange (upper extremity or above knee); minor Criteria: puckering/linear banding, superficial (plaque/patch), dermal papules, scleral plaques (subject aged <45 yrs). Pathology score 2, 3 or 4 required 2, 3 or at least 4 histological criteria respectively. Histological criteria include Increased cellularity with few other inflammatory cells, CD34+ spindle or epithelioid cells in a reticular or parallel arrangement with "tram-tracking," presence of fine collagen and ropey collagen surrounded by clefts, elastic fibers preserved and Septal involvement. A clinical score of 4 was suggestive of developing clinical signs consistent with NSF in subjects without biopsy.

    • Total Number of Participants With Clinicopathological Correlation of 'NSF' or 'Consistent With NSF' and Subjects Without Biopsy Developing Clinical Signs Consistent With NSF-cohort Analysis and Per Protocol Set [ Time Frame: Up to 24 months following the administration of Magnevist ]

Clinical score 2, 3 or 4 required more than 1 minor criterion, 1 major criterion or more than 1 major criterion respectively.
