"We are thankful for this extension to our one-time cash payment to HCRx," said Cokey Nguyen, President and Chief Executive Officer of Atara. "This flexibility allows us to focus on addressing the concerns in the latest CRL with the agency, supporting our partners, Pierre Fabre. We believe in the potential of tabelecleucel and are optimistic about the path forward."
In connection with the Amendment, the Company issued a warrant to purchase up to 400,000 shares of the Company’s Common Stock. The exercise price of the Warrant is equal to $0.0001 per share, subject to adjustment as provided therein, and the Warrants will be exercisable immediately and have no expiration date. The exercise of the Warrant is subject to a beneficial ownership limit as set forth in the Warrant.
"Tabelecleucel is proving to be an important option for European patients suffering from relapsed or refractory EBV+ PTLD, an ultra-rare and aggressive lymphoma," said Clarke Futch, Chairman and Chief Executive Officer at HCRx. "This amendment to our agreement provides Atara and their partner time to work with the FDA for a path to approval in the United States, where there remain limited treatment options and significant unmet need."
