Oryzon to Launch its First Product, GynEC Dx, a Non-invasive Test for the Detection of Endometrial Cancer

Reading time: 4 – 6 minutes

The outcome of the clinical trial for GynEC-DX, Oryzon’s first product, was presented recently at the 17th Biennial Meeting of the European Society for Gynaecological Oncology (ESGO) held in Milano (Italy). GynEC-DX, is a new diagnostic test for the early detection of endometrial cancer developed jointly with Reig Jofré Laboratories and expected to be launched on the Spanish market by 1Q-2012. According to the conclusions of this multi-centric double blind prospective clinical trial conducted in 16 Spanish hospitals under the supervision of Dr. Jordi Ponce, at Bellvitge Hospital, and Dr. Antonio Gil, at the Vall d’Hebron Universitary Hospital in Barcelona, GynEC-DX allows to rule out the presence of tumour in 97% of cases through a sample of uterine aspirate, thus allowing a better assessment of whether further analysis, as i.e. histeroscòpies, are indicated.

According to KOLs, there are two main problems with endometrial cancer, the most frequent tumour among women in Spain after breast cancer: the difficulty to detect all cases at an early stage and the discomfort, risks — and costs — associated with the current diagnostic tests, generally involving hysteroscopy. The new detection system developed by Oryzon, under the name GynEC-DX, provides a solution to both problems.

“We previously reported on the performance of molecular markers and the potential to analyze their levels in a sample that can be obtained in the gynecologists office with minimal discomfort to the patient” explains Carlos Buesa, the C.E.O. of Oryzon. This previous study, done in collaboration with Dr. Jaume Reventos and Antonio Gil at the Vall d’Hebron Universitary Hospital was chosen for the cover page of the printed issue of the International Journal of Cancer. “Nevertheless, that was a case control study, and we still had to show that our test could work in the real clinical routine. The results of the new double blind prospective study show that GynEC-DX performed very well and that together with the aspirate analysis became as potent as the more invasive hysteroscopy.”

The results of the clinical trial conducted in 16 Spanish hospitals were presented last week at the 17th Biennial Meeting of the European Society for Gynecological Oncology. GynEC-DX “was characterized by a high negative predictive value of 97% and a sensitivity and specificity of 81% and 96% respectively”. The test even detected some cases erroneously classified as negative by anatomic pathology on the aspirate and even one case missed by hysteroscopy but diagnosed after surgery. In combination with the classical anatomic pathological analysis on endometrial aspirates, the test had a sensitivity and negative predictive value of 92 and 99%, equaling that of hysteroscopy, and substantially reduced the failure rate of diagnosis on biopsies obtained by endometrial aspiration.

The main symptom of endometrial cancer is abnormal uterine bleeding. In peri-menopausal women, it is harder to decide whether uterine bleeding is abnormal, as in this phase of woman’s life, the menstrual cycle is highly irregular. According to Carlos Buesa, “60000 new cases of endometrial cancer are diagnosed in Europe every year, and more than 300,000 throughout the world. The cancer is considered highly curable — when detected early. Every year nevertheless, 74000 women die of the disease, and its incidence is increasing as the population ages. and due to the use of estrogen based therapies. In the case of Spain, we calculate that around 30,000 women in the peri-menopausal or post-menopausal period might benefit from this test to rule out or confirm the presence of endometrial cancer”.

The marketing of GynEC-DX, planned for Q1 2012 represents an important milestone in the history of Oryzon, founded in 2000, “as it will be the first product developed by the company to reach the market, a goal that very few European biotechnology firms have so far managed to achieve. With this launch, we will join this exclusive group and strengthen even further our position as one of the most competitive companies at the national and international level”, says Carlos Buesa.

At the moment, Oryzon is “exploring different options for the international commercialization of this product and there are conversations under way with several multinational companies in the diagnostic sector”. In addition, Carlos Buesa also remarks that “we are optimistic about the possibility of this test being included at public health-care services, as it would imply a diagnostic improvement, a substantial saving in the current costs related with the diagnosis of uterine cancer, shorter waiting times and less distress for patients”.
