Signature kidney injury & incidence

Hypertension — representative incidence ~42.4%.

Hypertension and proteinuria are common class effects; in the registrational VELOUR trial, grade 3-4 hypertension and proteinuria were more frequent with aflibercept plus FOLFIRI than with FOLFIRI alone. Nephrotic-range proteinuria and renal thrombotic microangiopathy are documented, including with the ophthalmic formulation, indicating a direct VEGF-trap mechanism. A meta-analysis of 15 trials (4,451 patients) put the summary all-grade hypertension incidence at 42.4%.

Renal toxicity profile

  1. HypertensionPrimary~44.2%All-grade hypertension 44.2% (95% CI 39.7-48.7), grade III/IV 22.6%, in a meta-analysis of aflibercept plus chemotherapy for metastatic colorectal cancer (2,889 pts, 10 studies); RR 6.30 vs control.
  2. Glomerular Injury / ProteinuriaSecondary~31.3%All-grade proteinuria 31.3% (95% CI 19.3-43.3), grade III/IV 7.4% (VEGF-trap podocyte injury), from the same aflibercept mCRC meta-analysis.
  3. Thrombotic MicroangiopathyRare

Onset timing & rechallenge

Subacute (~1–6 weeks) — Within weeks to a few months of therapy.

Mechanism of kidney injury

Sequestration of circulating VEGF-A (and PlGF) removes the endothelial survival and permeability signaling that maintains fenestrated glomerular endothelium, causing endothelial injury, loss of fenestrae, podocyte stress and proteinuria, reduced nitric-oxide-dependent vasodilation (hypertension), and renal-limited thrombotic microangiopathy. Because aflibercept binds the ligand itself (like bevacizumab), it produces a TMA-predominant lesion rather than the MCD/FSGS pattern more typical of receptor-blocking TKIs.

Clinical presentation

Hypertension with new proteinuria, sometimes nephrotic-range with edema; biopsy shows TMA (glomerular endotheliosis, capillary-wall double contours, mesangiolysis, intracapillary foam cells) and foot-process effacement.

Management

Antihypertensive therapy (ACE inhibitor/ARB favored); per label, suspend for urine protein >=2 g/24 h and resume at a lower dose when <2 g/24 h, and discontinue for nephrotic syndrome or any TMA. Renal abnormalities typically improve after drug discontinuation.

Risk factors

  • Pre-existing hypertension
  • Diabetes or baseline proteinuria/CKD

Prevention

  • Aggressive blood pressure control before and during therapy

Renal dose adjustment

No pharmacokinetic renal dose adjustment for a fusion-protein decoy; dose modification is driven by proteinuria thresholds and hypertension grade. Renal impairment does not alter clearance of the Fc-fusion molecule.

Dialyzability & ESKD dosing

Not dialyzable — a ~115 kDa Fc-fusion protein is not removed by hemodialysis or peritoneal dialysis; no dose change for dialysis patients.

Differential diagnosis

Ligand-trap (aflibercept/bevacizumab) renal injury skews toward TMA/endotheliosis on biopsy, contrasting with the MCD/FSGS pattern of VEGFR-TKIs; distinguish also from prerenal AKI and from chemotherapy (oxaliplatin/5-FU) effects within the FOLFIRI backbone.

Monitoring

  • Blood pressure every 2 weeks or with each cycle
  • Urine dipstick and/or UPCR during therapy (in practice, before each dose); 24-h collection if dipstick >=2+ or UPCR >1
  • Serum creatinine; CBC/LDH/haptoglobin and smear if TMA suspected

Key trials & series

  • VELOUR phase III trial of aflibercept + FOLFIRI in second-line metastatic colorectal cancer (carrying the hypertension/proteinuria signal)
  • Kikuchi et al. biopsy-proven aflibercept-associated renal TMA case (BMC Nephrol 2022)

Clinical pearls

  • As a VEGF ligand trap, aflibercept causes a TMA-type glomerular lesion, mirroring bevacizumab and the Eremina knockout model.
  • Even intravitreal aflibercept has caused renal TMA, underscoring how little systemic VEGF blockade the glomerulus tolerates.

Anticancer mechanism

Recombinant fusion protein combining the second Ig domain of VEGFR1 and the third Ig domain of VEGFR2 fused to the Fc of human IgG1, acting as a high-affinity soluble decoy that binds and sequesters VEGF-A, VEGF-B and placental growth factor (PlGF), blocking their interaction with native receptors and inhibiting angiogenesis. Used with FOLFIRI in metastatic colorectal cancer previously treated with an oxaliplatin regimen.

Note

Direct VEGF-A sequestration (like bevacizumab) predisposes to renal-limited TMA more than to glomerulopathy alone. The 'ziv-' prefix distinguishes the oncology formulation from intravitreal aflibercept, but the renal mechanism is identical.
