The presentation summarised the preliminary findings from patients with known or suspected endometriosis who were imaged with a SPECT-CT camera and subsequently underwent planned laparoscopic surgery, a key-hole surgical procedure to establish the presence, absence and location of endometriotic lesions. The imaging findings were compared to the surgical and histology reports and indicate that 99mTc-maraciclatide holds potential as a non-invasive test for early-stage endometriosis.
Specifically, these preliminary findings demonstrate that 99mTc-maraciclatide has the potential to:
– Visualise superficial peritoneal endometriosis which is found in the thin peritoneum lining which covers the abdomen and pelvis, and currently can only be identified accurately by surgery. This subtype accounts for c. 80% of all endometriosis diagnoses. In the patients in this study 99mTc-maraciclatide correctly identified superficial peritoneal endometriosis in those who went on to have this early-stage endometriosis confirmed by laparoscopy
– Highlight areas of activity in patients with deep endometriosis (often found on the organs e.g., bladder, bowel, rectum, ovaries) and endometrioma (cysts which are commonly found in the ovaries)
The presentation also outlined a case study on one patient with superficial peritoneal endometriosis which had not been identified by ultrasound, but which had been visualised with 99mTc-maraciclatide and later confirmed by laparoscopic surgery.
The ongoing study which will recruit 20-25 patients in total is being led by Professor Christian Becker, Co-Director of the Endometriosis CaRe Centre in Oxford, together with Professor Krina Zondervan, Head of Department at the Nuffield Department of Women’s and Reproductive Health, University of Oxford. It is anticipated that the study will complete later this year.
99mTc-maraciclatide is a radio-labelled tracer which binds with high affinity to the cell adhesion protein αvβ3 integrin and images angiogenesis (new blood vessel formation) which is known to be critical to the establishment and growth of endometriotic lesions.
David Hail, Chief Executive Officer of Serac Healthcare, said:
“These promising initial findings indicate that there is real potential for maraciclatide as a novel non-invasive method of diagnosing early-stage endometriosis. The ability to visualise the early stage of this disease is particularly significant as it cannot be seen by other imaging modalities, which contributes to the almost nine year average delay to secure a diagnosis. We are hugely encouraged by these results and look forward to continuing this work with the world-leading specialists from Oxford University.”
Professor Christian Becker, Co-Director of the Endometriosis CaRe Centre in Oxford added: “Endometriosis is a common disease affecting many millions of women worldwide with pain and infertility. The current delay in diagnosis results in prolonged suffering and uncertainty. Therefore, a novel imaging tool to assist healthcare professionals in identifying or ruling out the disease is urgently needed.”
Professor Krina Zondervan, Head of Department at the Nuffield Department of Women’s and Reproductive Health, University of Oxford added:
“Superficial peritoneal endometriosis is the most prevalent form of the disease. It often affects younger women for whom earlier diagnosis could enable intervention at an earlier stage, with the potential to significantly change outcomes and improve prospects. At the Endometriosis CaRe Centre at the University of Oxford our studies focus on identifying novel genetic, diagnostic and therapeutic targets for endometriosis. We are delighted about the early results of the DETECT study and are looking forward to recruiting more patients to consolidate the data.”
Maraciclatide is for investigational use only and is not approved by the FDA or UK and European regulatory authorities.

About endometriosis
Endometriosis is a common inflammatory disease that affects up to one in 10 women of childbearing age, about 190 million women worldwide. Endometriosis occurs when tissue similar to the lining of the uterus is found outside the uterus, predominantly in the pelvis, but sometimes also elsewhere in the body, e.g. lungs. The presence of this ectopic endometrial tissue can lead to inflammation and distortion of normal anatomy, which can cause significant pain and infertility. The diagnostic journey in those with endometriosis typically results in numerous visits to physicians and hospitals, along with multiple scans.
