Preliminary Ph1b/2 MAD data on track for 1H27 readout

In connection with its presentation at ASRS, KLRS announced incremental Ph1a

SAD data for TH103 in wet AMD. The expanded Ph1a SAD dataset included a total

of 17 treatment-naive patients in the efficacy analysis population (vs. 13 prior) and 3
