Nektar reports data from Phase 3 BEACON study of NKTR-102 Nektar Therapeutics presented biomarker data from a sub-study of the Phase 3 BEACON study of etirinotecan pegol (NKTR-102) which collected and analyzed circulating tumor cell samples from patients in the study. A total of 80% of the 852 patients enrolled in the BEACON trial participated in the CTC sub-study. Among the 627 patients who participated and had evaluable baseline samples, CTCs were detected in 97% of these samples. For the 611 evaluable baseline patient samples which yielded CTCs, potential NKTR-102 target-specific pharmacodynamic biomarkers were detected in the majority of samples. The pharmacodynamic biomarkers assessed in the CTC sub-study were chosen because of their potential ability to predict response to topoisomerase inhibition as well as to measure chemo-sensitivity in metastatic cancer patients
