258MO - Niraparib plus abiraterone acetate plus prednisone (NIRA+AAP) as first-line treatment in patients with BRCA+ metastatic castration-resistant prostate cancer (mCRPC): Second interim analysis in the Asian subgroup of the MAGNITUDE study

Published date:
11/27/2023
Excerpt:
In the BRCA+ cohort, improvement in rPFS by BICR was observed with NIRA+AAP (N = 17) vs. PBO+AAP (N = 19), with 71% reduced risk of progression or death (HR, 0.29, 95% CI, 0.11, 0.77)...Longer follow-up of the Asian subgroup confirms initial observations of a benefit from NIRA+AAP in BRCA+ mCRPC pts, which is consistent with the overall MAGNITUDE study results.

Excerpt:
Median rPFS in the BRCA1/2 subgroup was significantly longer in the niraparib + AAP group compared with the placebo + AAP group (16.6 v 10.9 months; hazard ratio [HR], 0.53; 95% CI, 0.36 to 0.79; P = .001)….Combination treatment with niraparib + AAP significantly lengthened rPFS in patients with HRR+ mCRPC compared with standard-of-care AAP.

Title:

High prevalence and heterogeneity of emergence of BRCA reversion mutations at progression on niraparib treatment in BRCA-mutant metastatic castration-resistant prostate cancer (mCRPC) patients

Published date:
03/09/2022
Excerpt:
Patients with reversion mutations showed better composite response (defined as ORR by RECIST 1.1, or CTC conversion to <5/7.5 mL blood, or ≥50% decline in prostate specific antigen) (74.2% vs 25.8%, p=0.01) and longer duration on treatment (median 6.9 vs 3.7 mo, p<0.05) compared to those without or low reversions. Additionally, patients with reversions trended to have longer median radiographic progression-free survival compared to those without or low reversions (8.1 vs 5.5 mo, p=0.12). In conclusion, the high prevalence of patients with BRCA reversion mutations and the displayed longer benefit from niraparib...

Excerpt:
At final analysis, with a median follow-up of 10·0 months (IQR 6·6–13·3), the objective response rate in the measurable BRCA cohort (n=76) was 34·2% (95% CI 23·7–46·0)….Niraparib is tolerable and shows anti-tumour activity in heavily pretreated patients with metastatic castration-resistant prostate cancer and DRDs, particularly in those with BRCA alterations.
