“After decades of frustration, efforts to develop antibodies that can ferry drugs into cancer cells — and minimize damage to healthy tissue — are gathering steam. The next generation of these ‘weaponized antibody’ therapies, called antibody–drug conjugates (ADCs), is working its way through clinical trials.
“Researchers will gather to discuss this renaissance on 30 November at the Symposium on Molecular Targets and Cancer Therapeutics in Munich, Germany. The improvements come after the first wave of experimental ADCs failed to deliver on its promise.
” ‘Initially there was a lot of excitement, and then slowly many of them did not work,’ says Raffit Hassan, a cancer researcher at the US National Cancer Institute in Bethesda, Maryland. Now, he says, there are two new ADCs in phase III clinical trials, and many more in earlier-stage testing.”
