Describes how this page is sourced, not how dangerous the drug is. Thinly sourced means fewer of the sourcing signals are met — not that the agent is kidney-safe. A rule-based summary, not a formal certainty appraisal.
The oral rapalog whose podocytes pay in protein — glomerular proteinuria and secondary FSGS, with occasional thrombotic microangiopathy.
Signature lesion
Proteinuria is a class effect of mTOR inhibitors, and with systematic monitoring it is close to universal. A retrospective review of 129 first-line metastatic renal-cell patients found any-grade proteinuria in 81% overall and in 96% of the everolimus arm (44 patients) — the highest of the three regimens compared, against 80% on pazopanib and 64% on bevacizumab. Almost all of it was minor: the study's grade 3-4 proteinuria (24%, 6 patients) occurred entirely in the bevacizumab group, none in the everolimus arm, and 35 of the everolimus patients (80%) simply continued at the same dose under monitoring. So the striking number is detection, not injury — heavy proteinuria and overt podocytopathy remain uncommon, and most nephrotic-range and biopsy-proven FSGS data are still extrapolated from the sirolimus/transplant literature. A phase II trial combining everolimus with bevacizumab reported grade 3-4 proteinuria of 25%, which reflects the added anti-VEGF effect and overstates everolimus alone. Thrombotic microangiopathy is rare and drawn mainly from case reports, typically with concomitant calcineurin-inhibitor or anti-VEGF exposure.Source: Land et al., J Oncol Pharm Pract 2016 (PMID 25505255, everolimus arm 44 patients, any-grade proteinuria 96%); Hainsworth JD et al., J Clin Oncol 2010 (PMID 20368560, everolimus + bevacizumab combination figure)
Proteinuria emerges over the first weeks to months; thrombotic microangiopathy usually within weeks to months, often with concurrent calcineurin-inhibitor or anti-VEGF exposure.

This agent's kidney lesions ordered by prominence — the #1 signature lesion first, then secondary and rare patterns. Cited incidence is shown where a citable figure exists; otherwise the tier stands qualitatively.
Damage to the filtration barrier — podocyte injury, FSGS and protein leak from VEGF and mTOR blockade.
Endothelial injury with microvascular thrombi, hemolysis and thrombocytopenia — gemcitabine, mitomycin C, anti-VEGF.
Renal electrolyte derangement — magnesium/potassium/calcium wasting (cisplatin, anti-EGFR antibodies) or retention (FGFR-inhibitor hyperphosphatemia, tumor-lysis hyperkalemia/hyperphosphatemia).

Glomerular Injury / Proteinuria
Damage to the filtration barrier — podocyte injury, FSGS and protein leak from VEGF and mTOR blockade.
Oral rapamycin analog (rapalog) that binds FKBP-12 to inhibit mTOR complex 1 (mTORC1), blocking downstream S6K1/4E-BP1 signaling. This arrests G1/S cell-cycle progression, suppresses protein synthesis and proliferation, and reduces HIF-1alpha-driven VEGF production, adding an anti-angiogenic effect.

Primary (non–case-report) references per year — a proxy for how actively the agent's renal literature is accruing. Recent years are highlighted. Reflects curation depth, not a systematic bibliometric count.
Single-patient and small-series reports, graded by evidentiary strength — A Strong (biopsy-proven plus a series and/or positive rechallenge), B Moderate, and C Limited (a single clinically-diagnosed case). Strongest first. Grades are inferred automatically from each report's abstract and journal — a heuristic ranking aid, not a formal quality appraisal.

Boxed warning
WARNING: MALIGNANCIES and SERIOUS INFECTIONS; KIDNEY GRAFT THROMBOSIS; NEPHROTOXICITY; and MORTALITY IN HEART TRANSPLANTATION WARNING: MALIGNANCIES and SERIOUS INFECTIONS; KIDNEY GRAFT THROMBOSIS; NEPHROTOXICITY; and MORTALITY IN HEART TRANSPLANTATION See full prescribing information for complete boxed warning. Only physicians experienced in immunosuppressive therapy and management of transplant patients should use everolimus ( 5.1 ) Increased susceptibility to infection and the possible development of malignancies may result from immunosuppression ( 5.2 , 5.3 ) Increased incidence of kidney graft thrombosis ( 5.4 ) Reduced doses of cyclosporine are required for use in combination with everolimus in order to reduce nephrotoxicity ( 2.4 , 2.5 , 5.6 , 12.7 , 12.8 ) Increased mortality in a heart transplant clinical trial. Use in heart transplantation is not recommended ( 5.7 ) Malignancies and Serious Infections Only physicians experienced in immunosuppressive therapy and management of transplant patients should prescribe everolimus. Patients receiving the drug should be managed in facilities equipped and staffed with adequate laboratory and supportive medical resources.

No dose adjustment is needed in patients with renal impairment [see Clinical Pharmacology (12.6) ].
Everything below is FAERS — adverse events someone chose to report, about 50,589 of them for this agent. Nobody counts the patients who were fine, so none of these numbers is an incidence, a risk, or a rate: they describe what gets reported, shaped by a drug's fame, its indication, and who was watching. How these numbers work.
Only significant signals appear (95% CI lower bound above 1) — a phenotype missing here was tested and did not reach significance, except Prerenal / Hemodynamic AKI, Pseudo-AKI, Renal Cysts, Chronic Interstitial Nephropathy — outside the clinician-reviewed MedDRA term map, never queried — and ATN and AIN, queried but biopsy-bound: real cases are filed as generic “acute kidney injury”, so their absence is not a negative. As of 2026-08-21.

Nearest agents by kidney-injury phenotype (shared injuries, nephron target, severity, class) — a similarity approximation, not a claim of shared drug identity or mechanism.
Same-class agents ordered by their documented kidney-injury profile — atlas severity, an acute-kidney-injury FAERS signal, and how many injury types each is documented to cause. Agents nearer the top carry the lighter documented renal profile.
A comparison of documented kidney-injury data within one drug class — not a substitution recommendation. Efficacy, indication, and non-renal toxicity differ between these agents and are out of scope here. Educational only, not medical advice.
