Description
Open-label non-randomised phase 2 trial in patients with recurrent or metastatic BRAF V600E mutant papillary thyroid cancer refractory to radioactive iodine. Patients had (cohort 2) or had not (cohort 1) previously been treated with VEGFR inhibitors. 51 patients were enrolled (26 cohort 1, 25 cohort 2). In cohort 1, partial response was achieved in ten (38.5%) patients. Nine patients achieved stable disease for at least 6 months (35%). Median PFS was 18.2 months and median OS not reached after a median follow-up pf 18.8 months. In cohort 2, six patients (27.3%) achieved a partial response and another six patients achieved stable disease for at least six months. Median PFS was 8.9 months and median OS was 14.4. months.
