TOPARP
Phase II trial of olaparib in patients with advanced castration resistant prostate cancer.
Disease site: Prostate cancer, urological cancers
Treatment modality: Systemic therapy
Status: In follow up
Trial details
TOPARP is an open label, two part adaptive design phase II trial to evaluate the anti-tumour activity of the PARP inhibitor olaparib in metastatic castration resistant prostate cancer. The trial will also identify molecular signatures of tumour cells in responding and non-responding patients, and clinically qualify putative predictive biomarkers of PARP inhibitor sensitivity.
Part A of TOPARP (TOPARP-A) closed to recruitment in October 2014 after recruiting 50 patients, who received 400 mg olaparib twice daily. The results were presented at the American Association of Cancer Research (AACR) conference in April 2015 and also published in the New England Journal of Medicine in October 2015.
Part B of TOPARP (TOPARP-B) closed to recruitment in July 2018 after recruiting a total of 98 patients. Potential participants had their tumour tissue analysed and only those with biomarkers predictive of olaparib response were eligible to enter TOPARP-B. Half of patients received 300 mg twice daily, and half received 400 mg of olaparib twice daily.
In both parts of TOPARP, patients receive olaparib until disease progression, after which they are followed up for an end of treatment safety assessment and every 3 months for life.
