I extend my gratitude to our prior Chief Financial Officer, Daniella Beckman, for her many contributions to Tango since its inception, including taking the Company public and leading multiple capital raises. We wish her well in future endeavors. We look forward to presenting key clinical data this year, including initial data from our combination trial with Revolution Medicines, Inc.'s RAS(ON) inhibitors."
