Abcodia Licenses the ‘Risk of Ovarian Cancer Algorithm’ (ROCA®)

Abcodia, the biomarker validation company with a focus on screening for cancer, has announced that it has entered into an agreement for an exclusive world-wide commercial license to the Risk of Ovarian Cancer Algorithm (ROCA) developed at Massachusetts General Hospital (MGH) and Queen Mary, University of London.

 

ROCA has the potential to be a major breakthrough for the early diagnosis of ovarian cancer. The diagnosis of ovarian cancer is usually made when the disease has spread outside the ovaries and as a result the outcome is poor. In the 80% of cases of ovarian cancer in which diagnosis occurs in the later stages, the 5-year survival rate is less than 20%. If diagnosed early, 5-year survival exceeds 85%. Hence the need for early diagnosis, in the hope that current treatments will be more effective. Around the world, an estimated 200,000 new cases of ovarian cancer are diagnosed in women each year and there are over 125,000 deaths.

ROCA is a test being validated for the screening of ovarian cancer. It was invented by Professor Ian Jacobs, Dean & Head School of Medicine, Faculty of Medical & Human Sciences, University of Manchester, and formerly of Queen Mary, University of London, and Dr Steven Skates of the Biostatistics Center, MGH, who together studied longitudinal patterns of CA125 in multiple cohorts of post-menopausal women to develop a statistical algorithm efficiently combining information in age and serial CA125 levels. ROCA has since shown excellent specificity, Positive Predictive Value (PPV) and sensitivity in large studies including UKCTOCS (UK Collaborative Trial of Ovarian Cancer Screening) and UKFOCSS (UK Familial Ovarian Cancer Screening Study).

A recent study1 by the MD Anderson Cancer Center in normal risk postmenopausal women reported a specificity of 99.9% and a PPV of 40% for ROCA when ultrasound was used as a secondary test. This confirms, in a USA population, results previously reported by the larger UKCTOCS trial involving 202,000 normal risk postmenopausal women. The published results from UKCTOCS2 indicate that, as well as achieving high specificity and PPV, ROCA can achieve a sensitivity of 89% for screen detection of ovarian cancer. UKCTOCS is a randomised trial comparing screening with standard care, and in 2015 will provide results on the impact of screening with ROCA on mortality and survival from ovarian cancer. The final data from UKCTOCS will be of great importance in guiding future clinical use of the ROCA in clinical practice.

Commenting on the recent MD Anderson publication, Professor Ian Jacobs, also Director of the UKCTOCS trial said “I am delighted to see the outcome of the MD Anderson 11 year study. The results reassuringly confirm in a USA setting those reported from the UKCTOCS prevalence study published in 2009. We now await further data from UKCTOCS in 2015 to establish whether the encouraging specificity and sensitivity data translate into improvements in survival and mortality which through early detection can help women affected by ovarian cancer.”

Dr Julie Barnes, Abcodia’s CEO, said: “The licensing of ROCA is a significant opportunity for Abcodia and we now intend to work with the co-founders to actively plan a commercialisation path that will in due course enable ROCA to be made available to women in Europe, US and around the world. We are currently in active discussions with partners in different territories to support our mission. Based on the reports to date and in particular the sensitivity, specificity and PPV data, we will begin to explore ways in which the ROCA could be implemented in clinical practice. The eventual clinical use will of course be informed and guided by the outcome of UKCTOCS and other clinical trials.”
