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.
A VEGFR tyrosine kinase inhibitor that throttles glomerular VEGF housekeeping signaling, producing the class triad of hypertension, proteinuria, and occasional renal-limited thrombotic microangiopathy.
Signature lesion
Proteinuria is common but usually low-grade, and reported any-grade rates span roughly 15% to 80% depending on the population and how proteinuria was ascertained. In a pooled secondary analysis of two phase III trials of pazopanib or sunitinib in metastatic RCC (n=1392, Sorich 2016), any-grade proteinuria occurred in 15.0% and grade 3/4 in 3.7% — a trial adverse-event figure covering both agents, not a pazopanib-specific rate. In a single-center first-line mRCC cohort, proteinuria was reported in 80% of the pazopanib-treated patients (Land 2016), most grade 1-2 and managed with continued monitoring at the same dose. Assume proteinuria is the expectation rather than the exception on pazopanib and schedule urine protein monitoring accordingly. Hypertension is one of the most frequent class effects, with severe (grade 3-4) hypertension a recognized class risk. Thrombotic microangiopathy is rare and largely case-level; biopsy-proven renal-limited and systemic TMA/TTP-like presentations have been reported.Source: Sorich, Br J Cancer 2016 (pooled phase III, pazopanib or sunitinib); pazopanib-specific cohort reports 80% (Land, J Oncol Pharm Pract 2016)
Proteinuria and hypertension within weeks to a few months; TMA case reports within the first weeks to ~2 months.
Distilled from: “Proteinuria and hypertension typically emerge within weeks to a few months of starting therapy; TMA case reports describe onset within the first weeks to ~2 months.”
Long-term outcome and threshold data distilled from the agent's cited literature — educational, not a substitute for the primary sources.
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.
Proteinuria from VEGF-signaling inhibition: mild/asymptomatic in ~21-63%, heavy (nephrotic-range) in up to ~6.5% of RCC patients; reflects glomerular podocyte/slit-diaphragm injury. PMID 20006922 (opens PubMed in a new tab)
Hypertension is among the most common adverse events with pazopanib in the pivotal phase III RCC trial; prospectively documented BP rise within 4 weeks of therapy. PMID 20100962 (opens PubMed in a new tab)
Uncommon; biopsy-proven drug-induced thrombotic microangiopathy reported at the case level (VEGF-inhibitor endothelial injury). PMID 33850692 (opens PubMed in a new tab)

Glomerular Injury / Proteinuria
Damage to the filtration barrier — podocyte injury, FSGS and protein leak from VEGF and mTOR blockade.
§ Receptor target map
VEGFR2 is the target with documented renal consequences across every VEGFR TKI; multi-kinase breadth beyond it (PDGFR-β, FGFR, and off-target receptor kinases) adds further renal and hypertensive liability. Select a lit receptor for its renal consequence.
VEGFR2 · renal target
Glomerular endothelial VEGFR2: loss of podocyte-derived paracrine VEGF signaling → fenestrae loss, nephrin downregulation, nitric-oxide depletion → hypertension, proteinuria, and thrombotic microangiopathy.
Oral multi-targeted tyrosine kinase inhibitor of VEGFR-1/2/3, PDGFR-alpha/beta, and c-KIT; blocks tumor angiogenesis by interrupting VEGF-driven endothelial proliferation and vascular sprouting.

8 primary references — trials, cohorts, mechanism, and reviews. Single-patient case reports are listed separately below, graded by strength. Citation metadata via PubMed / NLM.
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: HEPATOTOXICITY Severe and fatal hepatotoxicity has been observed in clinical trials. Monitor hepatic function and interrupt, reduce, or discontinue dosing as recommended [see Warnings and Precautions (5.1)]. WARNING: HEPATOTOXICITY See full prescribing information for complete boxed warning. Severe and fatal hepatotoxicity has been observed in clinical trials. Monitor hepatic function and interrupt, reduce, or discontinue dosing as recommended. (5.1)
Renal impairment — from the label
No dose adjustment is recommended for patients with renal impairment. Pazopanib has not been studied in patients with severe renal impairment or in patients undergoing peritoneal dialysis or hemodialysis.
Everything below is FAERS — adverse events someone chose to report, about 26,904 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 2026-10-01.

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.
The leading contributors to Pazopanib’s clinical kidney literature on PubMed, ranked by a blend of publication volume and citation impact — filtered toward clinical work via the PubMed Humans heading and clinical publication types (trials, cohorts, case reports, guidelines, reviews). Names link to that author’s work on Pazopanib; the PMIDs beside each name are up to three of their most recent papers on it, not the full count.
Ranked by a 50/50 blend of publication volume and a position-weighted, capped Relative Citation Ratio (NIH iCite) on this agent’s renal literature; the citation count shown is the raw total, not the ranking score — counted over the 41 clinical records among all 50 PubMed matches, so counts are within-sample — bibliometric context, not an endorsement or a measure of clinical authority.
