Brief Summary
The study hypothesis is that short-term low dose cyclophosphamide therapy will be effective in resolving inflammation in patients with late phase antibody-mediated rejection refractory to current standard of care treatment.

Eligibility Criteria
You may qualify if:
- Patients with a living or deceased donor kidney transplant
- Failed current standard of care for late antibody-mediated rejection
- Persistent de novo donor specific antibody and a concurrent biopsy with histologic evidence of acute antibody-mediated inflammation
- Adults with reproductive potential must agree to use approved methods of birth control while in the study
You may not qualify if:
- Leukopenia (WBC) \< 3.0 x 109/L
- Creatinine Clearance less than or equal to 25 ml/min/1.73m2
- HCV or HBV positive
- BKV or CMV viremia assessed by PCR
- Any active infection
- Use of other investigational drugs within 4 weeks of study
- Pregnancy/breast feeding/unwilling or unable to take birth control
- Active malignancy
- de novo DSA occurring equal to or greater than15 years after kidney transplant
- Screening biopsy with equal to or greater than cg2 on Banff criteria
- Cumulative/lifetime dose of cyclophosphamide, including anticipated total study dose (calculated according to Creatinine Clearance and mg/kg/day) equal to or greater than 36 g.
- Any condition that, in the opinion of the investigator, would pose risk to the subject's safe participation in the study
