  Purpose
The investigators goal is to evaluate the role of XOLAIR® in treatment of Acute Tubulointerstitial Nephritis (AIN) with the goal of shortening the duration and dose of prednisone for treatment of drug-induced AIN. Currently there is no good treatment for drug-induced AIN. Prednisone is the standard treatment but is associated with many side-effects when used long-term and at high doses.

Primary Outcome Measures:
  • Change in serum creatinine [ Time Frame: Baseline to three months ]

Secondary Outcome Measures:
  • Mean individual percentage drop in serum creatinine relative to entry creatinine levels [ Time Frame: baseline to 3 months ]
  • Percentage of subjects returning to their usual baseline creatinine (+25%) or below [ Time Frame: baseline to 3 months ]
  • Reduction in Neutrophil gelatinase-associated lipocalcin. [ Time Frame: baseline to 3 months ]
    24 hours, 4 hours, and in 3 months after Xolair treatment

  • Percentage of subjects requiring renal replacement therapy [ Time Frame: baseline to 3 months ]

Estimated Enrollment: 20
Anticipated Study Start Date: November 2017
Estimated Study Completion Date: December 2018
Estimated Primary Completion Date: September 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Omalizumab and Prednisone

Omalizumab in addition to prednisone. Omalizumab will be given once subcutaneously at a dose of 375 mg within 24 hours after receiving prednisone

Standard clinical therapy with prednisone.

  • Day 1-14: 60 mg/day 14 days (2 weeks)
  • Day 15-28: 40 mg/day (2 weeks)
  • Day 29-35: 30 mg/day (1 week)
  • Day 36-42: 20 mg/day (1 week)
  • Day 43-49: 10 mg/day (1 week)
  • Day 50-56: 5 mg/day (1 week)
  • Subjects will stop taking prednisone on day 57

If patients weigh less than 60 Kg, the dose will be adjusted accordingly (to equal 1mg/kg/day of prednisone as the starting dose).
