Momenta Signs Licensing Deal With Abbvie. Did It Have a Choice?

We previously reported that Momenta Pharmaceuticals reevaluated its biopharmaceutical strategy going forward, deciding to move forward only with its investigational adalimumab and aflibercept biosimilars. Yesterday, Momenta announced that it has joined the long queue of pharmaceutical manufacturers signing a biosimilar licensing deal with Abbvie, which will allow commercialization of M923, its biosimilar to Humira, should it obtain regulatory approval. Momenta’s licensing deal is the fifth one signed by prospective biosimilar marketers in the US.

This agreement was pretty much a no-brainer for Momenta. The company did not have the stomach for attempting either an extended patent fight or an at-risk launch. However, the biosimilar licensing agreement only allows Momenta to market its adalimumab biosimilar in the US after December 2023, which will make it the fifth Humira biosimilar that will launch under the licensing agreements (Table). The main patents for Humira have expired in Europe, and these agreements have generally allowed the European launches to occur as of October 16 of this year.

Of the manufacturers signing biosimilar licensing deals with Abbvie , only Amgen and Sandoz have earned FDA approval for Amjevita^® and Hyrimoz^®, respectively. And Boehringer Ingelheim is still duking out patent litigation with Abbvie in the courts over its approved biosimilar agent Cytelzo^®, for which it hopes to receive an interchangeability designation. The second through fifth agents entering the fight will be likely pounding away at subsequently smaller slices of revenue.

Perhaps the most frustrating part is that Abbvie is running a lucrative game; it will collect royalties from all of these manufacturers in 2023 and beyond, which will help offset declining marketshare from its biggest revenue contributor.
