§01
Signature kidney injury
Signature lesion
Dordaviprone carries no meaningful renal signal and no discrete published incidence of drug-related acute kidney injury. Its clinically important safety consideration is cardiac — QT-interval prolongation — rather than renal, and the intermittent oral schedule is generally well tolerated. Across its glioma program (Arrillaga-Romany, Neuro Oncol 2024, describes the phase 3 ACTION design and prior recurrent-disease efficacy), the toxicity profile is dominated by fatigue and QT effects, not nephrotoxicity. Any renal contribution would be indirect (prerenal physiology from intercurrent illness) rather than an intrinsic tubular or glomerular toxicity.Source: No meaningful renal signal; QT prolongation (not nephrotoxicity) is the safety focus (ACTION program, Arrillaga-Romany 2024)

§03
Kidney injury
Mechanism of kidney injury
Dordaviprone has no established direct renal toxicity. Its targets (DRD2 and mitochondrial ClpP) are not a nephron-specific injury pathway, and it is not primarily renally cleared, so the kidney is neither a target nor the elimination route. The only realistic routes to a kidney problem are indirect and non-specific: prerenal azotemia from volume depletion during an intercurrent illness, or an electrolyte disturbance that, combined with the drug's QT effect, raises arrhythmia risk (making potassium and magnesium worth keeping normal for cardiac rather than renal reasons). There is no described tubular, interstitial, or glomerular lesion attributable to the drug.
Clinical presentation
No characteristic renal presentation; renal function is expected to remain stable. The safety picture to watch is a prolonged QT (and its interaction with hypokalemia/hypomagnesemia), not a rising creatinine. A creatinine change on therapy is usually explained by an intercurrent prerenal insult rather than by the drug.
Management
No dordaviprone-specific renal management is required. Correct and maintain potassium and magnesium (for QT safety), restore volume for any prerenal creatinine rise, and address the precipitant. Investigate a progressive creatinine rise, proteinuria, or an active sediment as a separate renal process. There is no role for dialysis or drug-specific renal rescue for this agent.Lesion-level management framework
Risk factors
- Intercurrent volume depletion (vomiting, diarrhea, poor intake) causing prerenal physiology
- Electrolyte disturbances (hypokalemia, hypomagnesemia) — chiefly a QT/arrhythmia concern
- Concurrent QT-prolonging drugs
- Baseline CKD (lowers reserve for any intercurrent insult)
Prevention
- Keep potassium and magnesium normal — primarily to protect the QT interval, secondarily for renal-electrolyte health
- Maintain hydration during intercurrent GI illness
- Review co-medications for additive QT prolongation
- Routine chemistry and ECG monitoring per the drug's cardiac guidance
Anticancer mechanism· how it treats cancer
Oral small molecule, the first-in-class 'imipridone,' that acts as a selective antagonist of dopamine receptor D2/D3 (DRD2) and, more importantly for its antitumor effect, as an agonist of the mitochondrial protease ClpP; hyperactivating ClpP degrades respiratory-chain subunits, disrupting oxidative phosphorylation and triggering an integrated stress response and apoptosis, with particular activity in H3 K27M-mutant diffuse gliomas. It is given orally on an intermittent (weekly or twice-weekly) schedule.
§04
Clinical depth
Renal dose adjustment
No renal-impairment dose adjustment is established; dordaviprone is an orally administered small molecule given on an intermittent schedule and is not primarily renally cleared. Dose interruption/modification is driven by tolerability and by QT/cardiac considerations rather than by GFR.
Dialyzability & ESKD dosing
Not characterized as dialyzable and not clinically relevant: dordaviprone is not primarily renally eliminated, and there is no renal-clearance or drug-removal scenario in which dialysis is relevant. Renal replacement therapy would only ever address an unrelated AKI.
Differential diagnosis
Any renal abnormality in a patient on dordaviprone should be attributed to a cause other than the drug: prerenal volume depletion, a concurrent nephrotoxin, contrast, obstruction, or disease. The drug's own safety signal to track is the QT interval, amplified by hypokalemia/hypomagnesemia — an electrolyte-and-cardiac concern, not a tubular-injury one. A true renal lesion warrants an independent workup.
Monitoring
- ECG/QT interval per the drug's cardiac guidance (the key safety monitor)
- Serum potassium and magnesium (to protect the QT, and for general electrolyte health)
- Routine serum creatinine as part of standard care (no drug-specific renal surveillance)
- Volume status during intercurrent GI illness
Key trials & series
- ACTION (Arrillaga-Romany, Neuro Oncol 2024) — randomized phase 3 design of dordaviprone (ONC201) in newly diagnosed H3 K27M-mutant diffuse glioma after radiotherapy, following demonstrated efficacy in recurrent disease; the pivotal program whose toxicity profile centers on tolerability and QT rather than renal injury.
- Emerging targeted therapies in pediatric brain tumors (Terashima, No Shinkei Geka 2025) — review situating dordaviprone's accelerated approval for H3 K27M diffuse midline glioma within the precision-oncology landscape.
Clinical pearls
- Watch the heart, not the kidney: dordaviprone's safety signal is QT prolongation, and the nephron is largely a bystander.
- Keep potassium and magnesium normal mainly to protect the QT interval — a cardiac motive for an electrolyte habit.
- A creatinine rise on dordaviprone is almost always intercurrent volume depletion or another cause — investigate accordingly.
- Its dose is modified for tolerability and QT, not for GFR.
- The 'imipridone' class (ClpP agonism) does not carry a known nephron-specific toxicity.
