§01

Signature kidney injury

Drug-induced thrombotic microangiopathy (TMA) is a rare, case-level event for ixazomib and is not reliably quantified. In a pharmacovigilance analysis of the FDA Adverse Event Reporting System (FAERS, 2004-2023), proteasome inhibitors as a class were significantly associated with TMA (225 cases in 213 exposed individuals; ROR 1.71), but carfilzomib dominated the signal (58.7% of exposed individuals, 125 of 213; ROR 17.97), with bortezomib and ixazomib contributing far fewer reports. The ixazomib signal is therefore extrapolated largely from the class.Source: Deng et al., Support Care Cancer 2025 (FAERS pharmacovigilance)

§03

Kidney injury

Deep diveProteasome-inhibitor thrombotic microangiopathyWeeks into carfilzomib — often with an infection as the second hit — the microvascular endothelium tips into thrombotic microangiopathy: schistocytes and falling platelets, an acute kidney injury the drug set in motion, and an ADAMTS13 that comes back normal because this was never TTP.

Mechanism of kidney injury

Proteasome inhibition injures glomerular and microvascular endothelium, reducing endothelial production of protective factors (including VEGF and complement-regulatory proteins) and provoking platelet aggregation, microthrombi, and mechanical (microangiopathic) hemolysis. In the pooled PI-TMA literature, the median time to onset was about 8 days and most patients presented with the classic triad of hemolytic anemia (98%), thrombocytopenia (97%), and AKI (97%). Ixazomib TMA has been reported both as cumulative dose-dependent toxicity and via an immune-mediated mechanism; complement activation has been implicated, mirroring carfilzomib cases that responded to eculizumab.

Clinical presentation

Microangiopathic hemolytic anemia (schistocytes on smear, elevated LDH, undetectable haptoglobin, negative direct Coombs), thrombocytopenia, and AKI with rising creatinine, often with new or worsening hypertension. Gastrointestinal symptoms, fever, and fatigue frequently precede the laboratory triad.

Management

Discontinue ixazomib promptly when TMA is suspected; provide supportive care, transfusion as needed, and AKI management including dialysis when indicated (used in ~32% of pooled PI-TMA cases). TMA often improves after drug withdrawal (hematologic recovery ~96%, renal recovery ~93% in the pooled series). Plasma exchange has uncertain benefit in drug-induced TMA and is reserved for diagnostic uncertainty (suspected TTP); complement blockade with eculizumab has stabilized renal function in refractory proteasome-inhibitor TMA and can be considered.Lesion-level management framework

Risk factors

  • Prior or concurrent proteasome inhibitor exposure (especially carfilzomib)
  • Cumulative drug exposure
  • Underlying multiple myeloma with paraprotein burden
  • Pre-existing endothelial/renal compromise
Anticancer mechanism· how it treats cancer

Reversibly inhibits the chymotrypsin-like activity of the 20S proteasome (beta-5 subunit), causing accumulation of polyubiquitinated misfolded proteins, ER stress, and NF-kB-dependent apoptosis in malignant plasma cells. Used orally with lenalidomide and dexamethasone for relapsed/refractory multiple myeloma.

Note · TMA with ixazomib is rare and case-level; incidence is not reliably quantified. The signal is extrapolated from the proteasome-inhibitor class, where carfilzomib dominates.
§04

Clinical depth

Renal dose adjustment

No starting-dose change for mild renal impairment (CrCl >=30). For severe renal impairment (CrCl <30) or ESRD requiring dialysis, reduce the ixazomib dose from 4 mg to 3 mg. Hepatic impairment also requires reduction.

Dialyzability & ESKD dosing

Ixazomib is not meaningfully dialyzable (highly protein-bound, large volume of distribution); it may be given without regard to dialysis timing. Use the reduced 3 mg dose in dialysis-dependent patients.

Differential diagnosis

Distinguish drug-induced TMA from myeloma-related causes of AKI (cast nephropathy, hypercalcemia, paraprotein-associated TMA) and from TTP (check ADAMTS13) and atypical HUS (complement). The temporal link to PI dosing, normal ADAMTS13, and improvement on drug withdrawal favor PI-TMA.

Monitoring

  • CBC with smear review each cycle (platelets, schistocytes)
  • LDH and haptoglobin if cytopenias develop
  • ADAMTS13 activity when the TMA triad appears, to exclude TTP
  • Blood pressure at each visit
  • Serum creatinine each cycle

Key trials & series

  • TOURMALINE-MM1 (phase 3 ixazomib-Rd vs placebo-Rd in relapsed/refractory myeloma)
  • FAERS proteasome-inhibitor TMA pharmacovigilance analysis (Deng et al. 2025)

Clinical pearls

  • Carfilzomib carries by far the largest proteasome-inhibitor TMA signal; ixazomib reports are rare and the risk is largely class-extrapolated.
  • Look for the MAHA triad: schistocytes, undetectable haptoglobin, and thrombocytopenia with AKI.
  • Eculizumab has rescued renal function in refractory PI-TMA, supporting a complement-mediated component.

What gets reported — FAERS

Everything below is FAERS — adverse events someone chose to report, about 28,609 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.

  • Reporting odds ratio (ROR) — is kidney injury named in this agent's reports more often than in every other drug's? Above 1 means yes, disproportionately.
  • Renal phenotypes — the same question asked separately for each kind of kidney injury, so the ratios differ from the overall one and from each other.
  • Outcomes — a share of this agent's own reports, not of patients: how many were filed as involving a death or a hospitalization. Not a case-fatality rate.
FAERS reported renal phenotypes· 2 signals

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.
