Olaparib maintenance after platinum-based 1L (SOLO-1 — mPFS 56.0 vs 13.8 mo BRCA-mut) is treatment-defining; rucaparib + niraparib alternatives. SOLO-2 — 2L+ relapse maintenance.

CONTRA-AGGRESSIVE

Hard contraindications to escalation

What NOT to do

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

Aggressive plan (IND-OVARIAN-ADVANCED-1L-CARBO-PACLI-HRD-OLAP)

Do NOT skip HRD testing — defines maintenance choice (PARPi-only HRD+; niraparib-all-comer if HRD-negative weak benefit)
Do NOT start olaparib without confirmed CR/PR to platinum induction
Do NOT continue olaparib through Grade 3 anemia without dose reduction

Aggressive plan (IND-OVARIAN-MAINTENANCE-OLAPARIB)

Do NOT start without confirmed CR/PR to platinum
Do NOT continue past 2 years for non-BRCA HRD+ unless still benefiting (label allows ≤24 mo)
Do NOT skip pre-treatment counseling on long-term MDS/AML risk
