Cancer patient becomes first to receive 'landmark' treatment
The early-stage trial is testing donor-derived immune cells that target MAGE-A4, and researchers say many participants have few other survival options.
On Friday, Tracy Tomlinson, 58, became the first patient globally to receive ZI-MA4-1, an experimental engineered immune-cell therapy, at the Christie in Manchester as part of an early-phase clinical trial.
Tomlinson, diagnosed with advanced ovarian cancer shortly before Christmas 2020, endured multiple recurrences despite surgery and chemotherapy. Last year, the Christie's early-phase clinical trials team screened her and identified her as a suitable candidate.
Engineered Natural Killer cells with T-cell receptors target tumors producing the Mage-A4 protein. Dr. Jon Lim, consultant medical oncologist at the Christie, notes this living cell approach offers "a little bit more targeted" treatment than alternatives.
While the study primarily assesses safety, Tomlinson admitted being the first person in the world to receive the treatment sparked doubt: "Am I doing the right thing?" because it felt "a little bit scary."
Researchers designed ZI-MA4-1 as an off-the-shelf therapy, manufacturing hundreds of doses from a single batch to reduce costs and waiting times. The Christie and Royal Marsden in London are testing the therapy across ovarian, lung, sarcoma, and head-and-neck cancers.
