I have spent over 20 years running a tumor imaging metrics core at an academic cancer center. In that time, I have watched clinical trial enrollment concentrate at a relatively small number of flagship academic institutions. Unfortunately, trials do not propagate well to the community sites where most patients prefer to receive care. The explanations usually offered for why this happens have never fully accounted for what I observed.
In patients with extensive-stage small cell lung cancer, tarlatamab, a bispecific T-cell engager, plus durvalumab as first-line maintenance therapy extended median overall survival by more than eight months, more than tripled progression-free survival, and reduced the risk of death by 58% compared to durvalumab alone, according to the results of the phase III open-label, multicenter, randomized DeLLphi-305 study.
