Precautions and Warnings

urine protein-to-creatinine ratio (UPCR), serum cystatin C, and urine dipstick needs to be measured prior to starting Amondys 45. Consider measurement of glomerular filtration rate prior to initiation of this therapy.

Monitoring for kidney toxicity throughout the therapy is recommended. Obtain the urine sample before the infusion of Amondys 45 Injection or at least 48 hours following infusion.

Due to the effect of reduced skeletal muscle mass on creatinine measurements in those with DMD, no specific dosage adjustment is needed for DMD patients with renal impairment depending on estimated glomerular filtration rate. Patients with known renal function impairment need to be precisely monitored throughout Amondys 45 treatment.
