NOVA Results Bode Well Other Studies: The outstanding NOVA results, in our view, bode well for other ongoing and planned studies involving niraparib. We note that other clinical programs involving niraparib continue to progress well: (i) QUADRA, 4th line ovarian; (ii) PRIMA, 1st line ovarian; (iii) BRAVO, BRCA+ breast cancer; and (iv) combination trials involving: (a) niraparib plus KEYTRUDA, triple negative breast cancer and ovarian indications; and AVANOVA – niraparib plus bevacizumab, ovarian cancer.

Credit Suisse:

We expect broad use across ovarian cancer maintenance and niraparib looks clinically meaningful across BRCA and non-germline BRCA groups: Our peak ovarian cancer niraparib sales are $1.2B across 2nd line maintenance. Total ovarian sales across all lines of therapy on an adjusted basis are $1.8B (unadjusted $2.4B). In the BRCA cohort, the difference vs placebo was 15.5 mos. In the HRD/non-germline cohort, the difference vs placebo was 9 mos and the non-germline group difference was 5.4 months. Adverse events looked consistent with prior niraparib data. Rates of MDS/AML were consistent at 1.3% in niraparib and 1.2% in placebo. Discontinuation rates difference vs. placebo was 12%. This is roughly in-line with other ovarian trials that like OCEAN, CALYPSO, and ICON4 from speaking to mgmt.
