Selpercatinib

Hypertension — representative grade ≥3 incidence ~19.7%.

Hypertension is among the most common adverse events in LIBRETTO-001 (a frequent grade >=3 event), and a reversible serum-creatinine increase is also recognized. A single-center hereditary-MTC series found hypertension in ~26% on selective RET inhibitors. Reported rate: grade >=3 hypertension in 19.7% — 837 patients with RET-activated advanced/metastatic solid tumors receiving selpercatinib monotherapy (20 mg QD to 240… (Raez 2024, PMID 39471424).

Reported injury signatures: Hypertension, Prerenal / Hemodynamic AKI, Pseudo-AKI, Glomerular Injury / Proteinuria, SIADH / Hyponatremia.

1. HypertensionPrimary~14%Grade >=3 hypertension in 14% of RET fusion-positive NSCLC and 21% of RET-mutant medullary thyroid cancer (LIBRETTO-001); the most common grade >=3 adverse event
2. Prerenal / Hemodynamic AKISecondary
3. Pseudo-AKIRare
4. Glomerular Injury / ProteinuriaRareA single biopsy-worked-up, dose-responsive nephropathy case - distinct from the transporter creatinine artifact.
5. SIADH / HyponatremiaRareTwo drug-specific reports: SIADH with positive dechallenge, and tubular damage with symptomatic hyponatremia.

Subacute (~1–6 weeks) — Hypertension within the first weeks to months; creatinine changes early.

• Pre-existing hypertension
• Cardiovascular disease
• Concurrent nephrotoxins or QT-prolonging drugs

• Optimize antihypertensives before/during therapy

• Blood pressure at baseline, after 1 week, at least monthly, and as clinically indicated
• Serum creatinine periodically; cystatin C-based eGFR if a true GFR change is suspected
• ECG/QTc and liver enzymes per label

• LIBRETTO-001 (RET fusion-positive NSCLC and thyroid; RET-mutant MTC)
• LIBRETTO-431 (first-line RET fusion-positive NSCLC)
• Hamidi 2024 hereditary-MTC RET-inhibitor safety series

• Treat the blood pressure and check a cystatin C before assuming the creatinine rise means true GFR loss.
• Hypertension is the principal renal-relevant signal — manage it to keep patients on effective RET-directed therapy.
• Co-monitor QTc, since selective RET inhibitors prolong it and several antihypertensive/antiemetic co-medications also do.
• A biopsy-worked-up, dose-responsive nephropathy with nephrotic features is attributed to selpercatinib — separate from its transporter-mediated creatinine artifact.
• Two independent reports attribute dysnatremia to selpercatinib: SIADH improving on discontinuation (with successful reduced-dose resumption) and tubular damage with symptomatic hyponatremia and polyuria.
