AstraZeneca reports latest positive results for 'Lynparza'

AstraZeneca said on Friday that positive high-level results from the ‘PROpel’ phase 3 trial showed ‘Lynparza’, or olaparib, in combination with abiraterone, demonstrated a statistically significant and clinically meaningful improvement in radiographic progression-free survival (rPFS) versus standard-of-care abiraterone, as a first-line treatment for men with metastatic castration-resistant prostate cancer (mCRPC), with or without homologous recombination repair (HRR) gene mutations.

The FTSE 100 pharmaceuticals giant said that at a planned interim analysis, the independent data monitoring committee found that the trial met the primary endpoint of rPFS in men with mCRPC who had not received treatment in the first-line setting, including with new hormonal agents (NHAs) or chemotherapy.

It said it also showed a trend towards improved overall survival, although that data was still immature.

Prostate cancer is the second-most common cancer in men and despite an increase in the number of available treatments for men with mCRPC, five-year survival remains low.

“Today, men with metastatic castration-resistant prostate cancer have limited options in the first-line setting, and sadly often the disease progresses after initial treatment with current standards of care,” said executive vice-president of oncology research and development, Susan Galbraith.

“These exciting results demonstrate the potential for Lynparza with abiraterone to become a new first-line option for patients regardless of their biomarker status and reach a broad population of patients living with this aggressive disease.

“We look forward to discussing the results with global health authorities as soon as possible.”
