Analysis · ATRA · Life Sciences
The amendment to the commercialization agreement for tab-cel with Pierre Fabre Medicament is important as it reconfigures the potential revenue stream for Atara's lead product. While the potential regulatory milestone payments upon FDA approval were reduced by $9 million, the agreement introduces a new $15 million commercial milestone, resulting in a net increase of $6 million in total potential milestone payments.
