Four patients have an ongoing response at a median follow-up time of 20.2 months. The median progression-free survival is currently 22.4 months, and all patients are still alive.
Delcath also presented FOCUS Phase 3 trial update in metastatic uveal melanoma that were broadly consistent with prior presentations.
Overall survival (OS) data continues to mature, with a final, predefined analysis expected in May 2023, two years after the study's last treatment.
