At first relapse, a BRCA1/2-negative high-grade fallopian-tube carcinoma responds partially to carboplatin-gemcitabine after a 13-month treatment-free interval. Including initial therapy, two platinum courses have been completed and no PARP inhibitor has been used. Which maintenance route fits NICE TA784?

Correct answer: BNiraparib maintenance because she has responded after at least two platinum courses

TA784 recommends niraparib after a complete or partial response to the latest platinum course in relapsed platinum-sensitive high-grade ovarian, fallopian-tube or primary peritoneal cancer. In BRCA-wild-type disease, at least two previous platinum courses are required, which the initial and relapse regimens provide. Platinum sensitivity alone does not create a relapsed olaparib indication in BRCA-wild-type disease; first-line rucaparib and olaparib-bevacizumab have different biomarker and treatment-context requirements, while observation overlooks an eligible maintenance option.
