AstraZeneca What is the background for this study? What are the main findings?

Response: SOLO2 is a Phase III, randomized, double-blind, multicenter trial designed to determine the efficacy and safety of LYNPARZA tablets as a maintenance monotherapy compared with placebo, in patients with platinum-sensitive relapsed or recurrent gBRCA-mutated (BRCAm) ovarian cancer. The trial included 295 patients with germline BRCA1 or BRCA2 mutations who had received at least 2 prior lines of platinum-based chemotherapy and were in complete or partial response. The trial met its primary endpoint in October 2016, showing maintenance treatment with LYNPARZA significantly improved progression-free survival to a median of 19.1 months vs 5.5 months with placebo (a hazard ratio of 0.30; a 95% confidence interval of 0.22 to 0.41; a p value of <0.0001). What are the main findings?

Response: The latest results from SOLO-2 show that patients taking LYNPARZA had a median Overall Survival of 51.7 months vs. 38.8 months for patients on placebo, a difference of nearly 13 months, and reduced the risk of death by 26% (equal to a hazard ratio of 0.74 and p-value of 0.0537; not statistically significant). At five years, 42% of patients who received LYNPARZA were alive versus 33% on placebo, and 22% of patients who began the trial are  still receiving treatment with LYNPARZA. What should readers take away from your report?

Response: Overall Survival improvements in advanced ovarian cancer have not been seen since the introduction of chemotherapy almost two decades ago. The final Overall Survival analysis from the SOLO-2 trial adds to the broad set of evidence supporting the clinical value of LYNPARZA in women with ovarian cancer. What recommendations do you have for future research as a result of this study?

Response: The results from this study are promising and further our understanding of LYNPARZA in women with BRCA-mutated, platinum-sensitive relapsed ovarian cancer. We have a broad clinical trial program that will continue to explore how LYNPARZA impacts PARP-dependent tumors across multiple cancer types. Is there anything else you would like to add? Any disclosures?

Response: LYNPARZA is the only PARP inhibitor with seven indications across 4 different tumor types: ovarian, breast, pancreatic and prostate cancers. As we continue to follow the science in advancing targeted cancer treatment through biomarker-driven approaches, we hope to meet our goal of maximizing positive outcomes for patients living with DNA-deficient cancers.
