Primary current-line option

Standard plan

★ DEFAULT

Indication

IND-MTC-ADVANCED-1L-SELPERCATINIB

Regimen

Selpercatinib monotherapy (advanced/progressive RET-mutant MTC, 1L)

Drugs + NSZU

Selpercatinib (DRUG-SELPERCATINIB) 160 mg PO BID with food (≥50 kg); 120 mg BID (<50 kg) · Continuous, until progression or unacceptable toxicity · PO ✗ Not registered in UA

Reason

Primary current-line option per algorithm ALGO-MTC-1L: selected default was filtered; promoted first remaining current-line track

What NOT to do

Explicit prohibitive rules, each grounded in a regimen / supportive care / contraindication entity

Standard plan (IND-MTC-ADVANCED-1L-SELPERCATINIB)

Do NOT start systemic therapy in asymptomatic, structurally stable, slowly-rising-calcitonin MTC — observe with calcitonin / CEA q3-6 mo + imaging q6-12 mo.
Do NOT use radioactive iodine (RAI) in MTC — parafollicular C-cells do not concentrate iodide; RAI has zero efficacy.
Do NOT skip germline RET testing — ~25% of MTC is hereditary; positive germline drives kindred screening + pheochromocytoma surveillance + prophylactic-thyroidectomy timing in offspring.

Timeline

Data quality

Usable with caveats. No critical default-track gap was found, but the MDT should review the listed caveats before final sign-off.
