Study of DF1001 in Patients With Advanced Solid Tumors

DF1001-001 is a study of a new molecule that targets natural killer (NK) cells and T-cell
activation signals to specific receptors on cancer cells. The study will occur in two phases.
The first phase will be a dose escalation phase, enrolling patients with various types of
solid tumors that express human epidermal growth factor receptor 2 (HER2). Two combination
therapy cohorts will be opened for enrollment, DF1001 + nivolumab and DF1001 + Nab
paclitaxel. The second phase will include a dose expansion using the best dose selected from
the first phase of the study. Multiple cohorts will be opened with eligible patients having
either selected solid tumors, or solid tumors expressing high levels of HER2.
