International team of researchers set out to see whether Lu-PSMA-617 was more effective than standard care and recruited 831 patients with metastatic castration-resistant prostate cancer between June 2018 and October 2019. Patients were randomized to receive the treatment plus standard care or standard care alone.
The treatment significantly improved survival of patients by an average of four months, compared with standard treatment. Median survival time was 15.3 for the treatment group and 11.3 months for those receiving standard care.
Progression-free survival was also longer with the treatment: a median of 8.7 months compared with 3.4 months for those with standard care.
It is an effective and safe medicine that can improve standard of care for patients with this advanced prostate cancer.
Professor Ken Herrmann says: “This is a completely new therapeutic concept; a precision medicine that delivers radiation directly to a high incidence tumour. The treatment was well tolerated by patients and they had an average of four months’ longer survival with good quality of life. Lu-PSMA-617 can improve the lives of many men with advanced prostate cancer and their families.”
Professor Johann de Bono says: “Our findings show that this potent radioactive medicine can deliver radiation precisely to cancer cells and destroy them, extending patients’ lives. I hope men whose tumours have high levels of PSMA can soon benefit from this highly innovative treatment.
Currently, the treatment is being appraised by the National Institute for Health and Care Excellence (NICE) for use in the NHS in England and Wales.”
“Using the PSMA molecule to directly target prostate cancer cells is the beginning of a new era of precision medicine in urology diagnostics as well as therapy”, says Professor Peter Albers, Head of the Department of Urology, Dusseldorf University, and Chair of the Scientific Office of the EAU.
“LU-PSMA-617 was tested in so-called end-stage disease and still showed superiority and this paves the way for studies to treat patients in earlier stages. We have seen similar success in the diagnostic setting, using this molecule to improve the way we stage tumours. This targeted approach will revolutionise the way we approach the treatment of men with prostate cancer in the future.”
