Protagonist can opt out of its co-development deal with Takeda post-NDA filing. This move triggers a $400 million payment and converts the partnership to a high-royalty model (14-29%). This structure allows them to de-risk commercialization while retaining significant financial upside, effectively creating a lucrative licensing deal on demand.
Protagonist believes its oral IL-23 blocker will not just compete with existing injectables but will capture a new market. They target the over 50% of eligible patients who currently take no therapy due to a dislike of injections or the safety profiles of other oral options, thereby expanding the total addressable market.
Acknowledging its late entry into the crowded obesity market, Protagonist consulted key opinion leaders to define the ideal drug profile: an oral "triple G" agonist. By using its peptide platform to build exactly what experts requested, the company aims to leapfrog competitors with a best-in-class product rather than an incremental improvement.
