Momenta Drops Out of Biosimilar Adalimumab Competition

In reporting its second quarter earnings, Momenta Pharmaceuticals stated on August 2 that it no longer plans to market M923, its biosimilar version of Humira®.

“Today, Momenta announced the Company will cease active development of M923 at this time, due to changes in the market opportunity associated with Humira patent litigation settlements,” according to a company press release.

In 2018, Momenta decided to drastically scale back its biosimilar development as part of a strategic review. However, it continues to partner with Mylan on one remaining biosimilar candidate, M710. This is a biosimilar version of aflibercept (Eyela®).

Momenta’s troubles were first apparent after it completed its phase 3 trial of M923 in psoriasis. The clinical study pitted the biosimilar versus the EU-licensed version of adalimumab, and was successfully completed in 2017; however, no FDA filing ensued, despite a company announcement that it would occur in 2018. Later that year, the company stated that it delayed filing for financial reasons, but it would continue to seek a partner to commercialize the product.

In 2018, it signed a licensing agreement with AbbVie, which would have allowed it to launch in December 2023—in the back of the pack of licensed biosimilars in terms of timing (which could not have helped its efforts to seek a partner). In view of its refocusing its strategic outlook, the delay in filing a 351(k) biologic licensing application (BLA) application with the FDA may have made some sense from a couple of perspectives

First, the company may have thought twice about continuing expenditures if it was undecided as to whether it would remain committed to the biosimilar development. These expenditures could be quite significant (beyond payment of user fees) if the FDA requested additional data in an initial review of the BLA.

Second, with a potential launch date of December 2023, Momenta certainly had time to get its ducks in a row. If a commercialization partner could be lined up before the BLA filing, that company could help shoulder additional associated costs.

In any case, Momenta’s pull back is not entirely unexpected. Though it intended to file an application with the European Medicines Agency early this year (which would not have required a further delay in launch), this also did not occur (probably because of existing biosimilar adalimumab competition in Europe).

Momenta’s pipeline, beyond aflibercept, consists of other biologics for rare diseases. Its marketed products are for generics of Copaxone® and Lovenox®.

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.
