Targeting annexin-A1 can halt cancer cell growth, study finds

A brand new examine printed in Oncogene highlights the effectiveness of MDX-124, the primary therapeutic drug to focus on annexin-A1, a protein that’s overexpressed in a number of most cancers sorts and promotes tumor development.

The analysis was led by Professor Chris Parris and Dr. Hussein Al-Ali at Anglia Ruskin College (ARU) in collaboration with Professor Chris Pepper of Brighton and Sussex Medical Faculty and UK biotech firm Medannex, which has produced the MDX-124 monoclonal antibody remedy.

Excessive annexin-A1 expression levels correlate with poorer total survival in numerous cancers that presently have restricted treatment optionstogether with triple-negative breast, pancreatic, colorectal, and prostate cancers.

The new study discovered that MDX-124, which is being developed to be used in immunotherapy, considerably reduces proliferation throughout various human most cancers cell traces expressing annexin-A1. This anti-proliferative impact is instigated by stopping cell cycle development.

Moreover, MDX-124 is proven to considerably inhibit tumor progress in in vivo fashions of triple-negative breast and pancreatic most cancers, indicating that annexin-A1-targeted remedy represents a viable and progressive method to most cancers therapy.

The section Ib clinical study of MDX-124, known as ATTAINMENT, is presently underway to ascertain the security and optimum dose of the novel remedy. Its medical efficacy will then be evaluated in newly recognized most cancers sufferers together with present acceptable remedies.

Professor Chris Parris, Head of the Faculty of Life Sciences at Anglia Ruskin College (ARU), stated, “We all know that the protein annexin-A1 prompts formyl peptide receptors to provoke a fancy community of intracellular signaling pathways, which may result in quite a few mobile responses, together with tumor initiation and development.”

“We’ve got demonstrated on this new examine that utilizing MDX-124 can scale back cell growth in annexin-A1-expressing most cancers cells each in vitro and in vivo, offering additional proof that annexin-A1 is a legitimate goal for remedy in most cancers.”

Medannex Director of Scientific Operations, Dr. Fiona Dempsey, who co-authored the paper, stated, “We’re delighted to publish this work with our collaborators demonstrating the anti-cancer potential of our progressive antibody therapeutic and look ahead to the clinical data popping out of the ATTAINMENT examine in the end.”
