Elacestrant

Prerenal / Hemodynamic AKI.

Direct nephrotoxicity is not a recognized feature. In the pivotal phase 3 EMERALD trial the dominant toxicities were nausea, fatigue, vomiting and decreased appetite; a discrete renal-injury rate was not reported. Any renal involvement is best understood as indirect/case-level (e.g., volume depletion from GI toxicity).

Reported injury signatures: Prerenal / Hemodynamic AKI.

Variable / unpredictable — Renal events are uncharacterized; any prerenal AKI would track GI toxicity.

• Volume depletion from nausea/vomiting/poor intake
• Pre-existing CKD
• Concurrent nephrotoxins
• Strong CYP3A4 interactions affecting exposure (pharmacologic, not directly renal)

• Antiemetic prophylaxis and adequate hydration/intake
• Review CYP3A4 drug interactions

• Nausea/vomiting severity and volume/intake status
• Liver function and CYP3A4-interacting comedications

• EMERALD (Bidard JCO 2022) — pivotal phase 3
• EMERALD ESR1-mutant subgroup analyses (Bardia Clin Cancer Res 2024)

• GI, not renal: elacestrant's defining toxicity is nausea — any AKI is most likely prerenal from volume loss.
• Renal literature is absent; keep claims qualitative and conservative.
