# When compared to the negative control patients, the OS and PFS of the WT1-specific DTH-positive patients were noticeably better. Specifically, the median OS for all three PDA patients who experienced strong DTH reactions was 717 days. # Compared to patients receiving the WT1/DC/I or WT1/DC/II vaccines, individuals with PDA who received the WT1/DC/I+II vaccine had a significantly longer MST (P = 0.036) and median PFS (P = 0.010). The gene discussed is WT1; the disease is Patent ductus arteriosus.
