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 JAK2/IRAK1/ACVR1 inhibitor for cytopenic myelofibrosis whose kidney risk is indirect — severe diarrhea drives volume and electrolyte depletion into prerenal azotemia, not intrinsic nephrotoxicity.
Signature lesion
Pacritinib has no established intrinsic nephrotoxicity; its renal risk is a downstream consequence of its dominant gastrointestinal toxicity. Diarrhea is the signature adverse effect — in the phase 2 study grade 1/2 diarrhea occurred in ~69% of patients and nausea in ~49% (Komrokji 2015), and in the PERSIST-1 phase 3 trial grade 3-4 diarrhea occurred in ~5%. In real-world FAERS pharmacovigilance, gastrointestinal disorders were the top disproportionality system-organ-class and diarrhea the most-reported preferred term (Zhang 2025). High-volume diarrhea (often with nausea/vomiting) can precipitate volume depletion, hypokalemia/hypomagnesemia, and prerenal azotemia, but a specific incidence of pacritinib-attributable acute kidney injury has not been separately quantified — so no headline AKI rate is quoted here.Source: 25762180
Diarrhea (and the prerenal azotemia/electrolyte loss that tracks it) emerges within the first days-to-weeks and is most pronounced over roughly the first 8 weeks — early and episodic, not cumulative.
Distilled from: “Diarrhea is an early effect, typically emerging within the first days-to-weeks of therapy and most pronounced over roughly the first 8 weeks; it tends to be self-limited and to improve with continued treatment, antidiarrheals, and dose management. Any prerenal azotemia and electrolyte disturbance tracks the diarrhea temporally and is therefore early and episodic rather than cumulative or delayed.” · PMID 25762180 (opens PubMed in a new tab)
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.
Renal hypoperfusion from capillary leak and cytokine storm — IL-2 and CAR-T cytokine release syndrome.
Renal electrolyte derangement — magnesium/potassium/calcium wasting (cisplatin, anti-EGFR antibodies) or retention (FGFR-inhibitor hyperphosphatemia, tumor-lysis hyperkalemia/hyperphosphatemia).
Direct death of tubular epithelial cells — the dose-limiting lesion of the platinums and zoledronate.

Prerenal / Hemodynamic AKI
Renal hypoperfusion from capillary leak and cytokine storm — IL-2 and CAR-T cytokine release syndrome.
Oral small-molecule kinase inhibitor with activity against JAK2 (including the JAK2 V617F mutant), FLT3, IRAK1, and ACVR1 (ALK2), while notably sparing JAK1. By dampening constitutive JAK2-STAT signaling it reduces splenomegaly and constitutional symptoms of myelofibrosis; because it spares JAK1, it can be dosed in patients with severe thrombocytopenia in whom ruxolitinib and fedratinib worsen cytopenias. Potent ACVR1 inhibition suppresses hepcidin production, contributing an anemia/transfusion-independence benefit, and IRAK1 inhibition attenuates NF-kB-driven inflammatory signaling.

Everything below is FAERS — adverse events someone chose to report, about 2,964 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.
