Association between ribociclib and changes in creatinine in patients with hormone receptor positive metastatic breast cancer

Abstract: Combination ribociclib and aromatase inhibitors are currently the preferred treatment in Australia for newly diagnosed hormone receptor positive metastatic breast cancer in the absence of visceral crisis. In our case series of 32 patients, 28% experienced grade 1 elevations in creatinine, a toxicity that was under‐recognised in large phase III studies. Creatinine rise appears to be due to a reversible inhibition of renal efflux transporters rather than an acute kidney injury in the majority of cases.

“…7 Like many other drugs, CDK 4/6 inhibitors, that is, abemaciclib, have been shown to cause a transient and mostly reversible elevation in serum creatinine (SCr) and a corresponding reduction in estimated glomerular filtration rate (eGFR) without affecting kidney function. [8][9][10][11] Herein, we report the first case of pseudo-acute kidney injury (pseudo-AKI) in a patient on ribociclib-verified using both cystatin-based eGFR and measured GFR by urinary iothalamate clearance.…”

“…9 (%28) patients had grade 1 creatinine elevation and none discontinued therapy or had dose reductions for this reason. 14 In our case; Naranjo algorithm for adverse drug reaction is calculated as 9, which is classified as definitive adverse drug reaction and our patient was evaluated as grade 3 AKI due to Common Terminology Criteria for Adverse Events version 4.0. The detection of grade >2 acute AKI may lead clinicians to perform further examinations or even invasive tests.…”

“…In a study by Wilson et al; if grade 3 AKI occurs, restarting at reduced dose ribociclib is recommended. 14 Based on this study, ribociclib treatment was re-initiated with lower dose(400 mg daily). However, grade 3 AKI recurred despite dose reduction (creatinine: 2.5 mg/dl).…”

“…Moreover, at clinically relevant concentrations it also inhibited BCRP, OCT2, multidrug and toxin extrusion protein (MATE) 1, and bile salt export pump (BSEP) [15,29,56,68]. In a retrospective study in patients treated with ribociclib, creatinine levels increased 37% compared to baseline, probably due to OCT2 inhibition [69].…”
