IMPACT study: Matched targeted therapy improves survival in advanced cancer



“We [also] wanted to see if adding the intervention ... would hold significance in this multivariate model, and we found that ... nonmatched therapy was associated with adverse survival; it was an independent factor associated with worse survival,” she said. “Therefore, matched targeted therapy is associated with longer survival.”

In the randomized, phase 2 trial IMPACT 2, progression-free survival will be compared in patients with and without matched targeted therapy, and the prognostic scoring system developed as part of IMPACT to predict overall survival based on baseline characteristics will be further evaluated, she said.

During a discussion of the findings during the press briefing, ASCO Expert Catherine M. Diefenbach, MD, said the type of precision medicine studied in IMPACT is “the wave of the future.

“Large scale efforts such as ASCO’s TAPUR or the NCI-MATCH trial will bring these efforts to many, many more patients, and hopefully usher in a new way of treating advanced cancer patients that will improve overall survival for many more patients,” said Dr. Diefenbach, of New York University.

Dr. Tsimberidou reported a consulting or advisory role with Roche, as well as research funding to her institution from EMD Serono, Baxter, Foundation Medicine, ONYX, Bayer, Boston Biomedical, Placon, IMMATICS, Karus Therapeutics, and StemCells.
