AstraZeneca and MSD present new results about Lynparza

AstraZeneca Research and Development

The two pharma giants reports data which showed clinical improvement in median radiologic progression-free survival (rPFS) with Lynparza (olaparib) in combination with abiraterone compared to abiraterone monotherapy, a standard of care, in metastatic castration-resistant prostate cancer (mCRPC).

Lynparza is being jointly developed and commercialised by AstraZeneca and MSD.

Phase II trial

The results of Study 08, a randomised, double-blinded, multi-centre Phase II trial, comparing Lynparza in combination with abiraterone (n=71) to abiraterone monotherapy (n=71) in patients with previously-treated mCRPC, regardless of homologous recombination repair (HRR) mutation status, were presented at the 2018 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago, US, 1-5 June 2018 as a “Best of ASCO presentation” and were published online today in the Lancet Oncology. The primary endpoint was rPFS. Secondary endpoints included time to second progression or death (PFS2), overall survival (OS) and health-related quality of life.

“A previous trial demonstrated improvements in response rates with Lynparza monotherapy in metastatic castration-resistant patients with HRR mutations. The Study 08 combination data suggests that regardless of their mutation status, men with metastatic castration-resistant prostate cancer may potentially benefit from Lynparza in combination with abiraterone,” says Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca.
