Proceeds from the registered direct offering and the warrant exercises, together with the upfront license fee from 3D Medicines, will be used to fund the Company’s development programs for GPS, including the ongoing pivotal global Phase 3 clinical trial (the REGAL study) of GPS in patients with acute myeloid leukemia (AML) who have reached second complete remission, as well as regulatory- and CMC-related preparatory projects supporting a future potential GPS biologics licensing application (BLA) filing for GPS, assuming positive data from the REGAL study.

"We are pleased that we have been able to significantly strengthen our balance sheet with the proceeds from the registered direct offering of common stock and the warrant exercises as well as the expected upfront license fee. These proceeds, together with our current cash, will allow us to aggressively execute on our clinical development plans, including taking steps to mitigate, to the extent possible, the impact of the COVID-19 pandemic on our clinical trial timelines as well as, among other things, to begin preparations for potential regulatory filings around our Phase 3 REGAL AML study," commented Angelos Stergiou, MD, ScD h.c., President and Chief Executive Officer of SELLAS.
