Geron has also contributed all of the clinical and regulatory documents pertaining to the OPC1 and VAC1 (autologous dendritic cells) clinical trials, as well as a series of stem-cell-related out-licenses. Asterias has entered into an exclusive sublicense with Geron for using telomerase as an antigen for the VAC1 and VAC2 (hES-derived dendritic cells) product candidates.
