Researchers present a new potential "weapon" for the destruction of tumour cells. Its name is MEN1309 and this new antibody is currently being studied by researchers at Menarini and Oxford Bio Therapeutics (OBT) against Non Hodgkin's lymphomas and solid tumours.

• CONTEXT: As part of the agreement undertaken in October 2012 between Berlin Chemie/Menarini Group and the UK company Oxford BioTherapeutics (OBT), a second biotech molecule candidate for clinical development for the treatment of cancer has been selected. The first molecule, the MEN 1112 for the treatment of Acute Myeloid Leukemia, was designated by Menarini and OBT last December 2013*. The contract between Menarini and OBT covers the development of 5 antibodies for the treatment of cancer, foresees an investment in research of more than 800 million Euro over a multiyear time span.
• TARGET OF MEN 1309: Lymphomas and solid tumours. The product goes under the name of MEN 1309 and is a new monoclonal antibody conjugated to a toxin. In the first in vitro and in vivo experiments carried out, MEN 1309 has shown significant therapeutic potential against both Non-Hodgkin's lymphomas and solid tumours, particular those of a specific subtype of breast cancer.
• ACTION MECHANISM: MEN 1309 belongs to a new class of anti-tumour biological drugs. This class of drugs acts through an innovative mechanism called ADC, Antibody Drug Conjugate, which are antibodies conjugated with a toxin or "armed antibodies". In fact these actually work as weapons capable of hitting their target with pinpoint accuracy. At first they act as if they were highly sophisticated keys by binding with a specific antigen, which is the ‘lock' on the cell surface, gaining selective access to the tumour cell. Once they are inside the cell they then become lethal weapons, releasing their potent toxin; a real bomb capable of destroying cancer cells. This new class of "armed" antibodies represents an important step forward in the treatment of cancer. Indeed, being able to selectively target the malignant cell, can greatly increase the antitumour effect as well as reducing the toxic effects on healthy tissue. Researchers at Menarini have already developed the biotechnological process necessary for producing the antibody and are now preparing to get the in vitro and in vivo studies underway. This, in turn, will allow clinical trials to start in the second half of 2016.

Andrew Slade, Chairman of Menarini Biotech, a company belonging to the Menarini Group commented: "We are extremely pleased with the progress of our strategic oncology alliance with OBT. Berlin Chemie/Menarini has a long-standing commitment to advancing the treatment of cancer, and we look forward to accelerating our shared pipeline of novel antibody-based therapies into clinical development."

"We are delighted to be able to initiate the development of the second oncology programme further to our partnership with the Menarini Group," said Dr Christian Rohlff, Oxford BioTherapeutics' CEO. "This is a further milestone for OBT given that we now continue to advance our cancer therapies to the clinic. We have combined proven ADC technologies with our target discovery capabilities to build a pipeline of novel cancer therapeutics. We look forward to progressing further programmes into clinical development thanks to our agreement with Menarini."

*UPDATE ON FIRST ANTIBODY: MEN 1112, the monoclonal antibody for the treatment of Acute Myeloid Leukemia designated by Menarini and OBT to be the first project last December 2013, has now successfully completed the pre-clinical trials stage and has demonstrated a promising efficacy and a good tolerance level. The translational studies for the pre-clinical staged the MEN 1112 were carried out in the Menarini Research Campus in Pomezia (Rome) in collaboration with the Tor Vergata University. The Phase 1 clinical trials of MEN 1112 are expected to start over the next few weeks in Belgium on patients affected with Acute Myeloid Leukemia. The study, involving approximately 50 patients, shall also shortly be initiated in Italy, France, and Germany. The first results are expected for the year 2016.
