*Purpose: Previous trials have not examined differences in patient-reported outcomes (PRO) between belatacept (BELA)- and tacrolimus (TAC)-based therapies in adult kidney transplant (KTx) patients (pts). The BEST Trial (Belatacept-based Early Steroid-withdrawal Trial) was designed to compare 2 BELA-based early steroid withdrawal (ESW) regimens with a TAC-based ESW regimen across 2 years. Our hypothesis was that patients on BELA will have fewer immunosuppressant-related symptoms and improved quality of life (QoL).
*Methods: This longitudinal, multisite study was conducted under an FDA IND and IRB across 8 sites. All pts (n=315) received mycophenolate therapy and 5 days of steroids; and, were randomized to 3 groups: alemtuzumab+BELA, r-ATG+BELA, and r-ATG+TAC. Pts completed two PRO measures at baseline and 12 months (MEMPHIS Survey, MTSOSD-59R Survey).
*Results: Intent to treat analyses on 264 patients with 1 year follow-up were completed. Those on BELA-based therapies generally reported higher gains in quality of life from baseline to one year; and, reported a lower probability of experiencing adverse events at one year. No significant differences were observed between groups for total QoL, misc side effects, GI distress, emotional burden, life/role responsibilities or mobility as measured by the MEMPHIS change weighted scores or the symptom occurrence or symptom distress scales in the MTSOSD-59R. Alemtuzumab+BELA and r-ATG+BELA groups were compared to r-ATG+TAC group at 1 year and differences in individual symptom scores were observed.

*Conclusions: Our results show that a TAC free and steroid free BELA-based regimen resulted in a tendency toward improved PROs at 1 year. Neurologic, gastrointestinal, and mobility symptoms were reported less frequently in the BELA-based regimens across both measures with a >15% difference reported in trembling hands. BELA-based protocols reported more problems participating in leisure past-times.
