Co-clinical trial shows potential of PDX models in early-phase clinical trials
Patient derived xenograft (PDX) models – which utilize tissues or cells from patients for in vivo tumor studies – are used to study antitumor activity and mechanisms of intrinsic and acquired resistance, but it is unclear how well they translate to clinical responses. To address this, researchers led by Funda Meric-Bernstam, M.D., developed PDX models in a co-clinical trial to compare against patient responses with the bispecific HER-2 targeted antibody zanidatamab. Of 36 tumors implanted, the researchers established...
