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.

With the Samsung Bioepis Deal, Abbvie Tightening Its Grip on the US Adalimumab Market

Samsung Bioepis and Biogen has reached a deal with Abbvie that would enable it to market its biosimilar adalimumab (should it be granted approval) in June 2023. This is the second deal Abbvie has made with a potential competitor, confirming the solidity of its patent wall. The European patent expires in October 2018, and competitors will be able to sell biosimilars over the pond unhindered at that time.

However, without competition, most expect unencumbered price increases until a US biosimilar introduction. In other words, biosimilars will not make an appreciable impact on the cost of adalimumab in the US market, unless another biosimilar manufacturer decides to launch at risk in the near future.

A Deal Prior to FDA Approval

The agent, SB5 has not yet been filed for approval in the US. Samsung filed its application for approval in the EU in July 2016 and was authorized by the European Medical Agency in August 2017. Biogen will market the agent for Samsung, whenever it is launched.

Amgen inked a deal with Abbvie in September 2017, effectively ending its patent battle. This deal gives Amgen a jump on other competitors that reach settlements with Abbvie, by allowing a launch in January 2023. In addition, other manufacturers are working on adalimumab biosimilars, including Coherus and Sandoz. The biggest question though is Boehringer Ingelheim’s move, as they have the only other FDA-approved adalimumab biosimilar approved on the marketplace (but also unlaunched). Boehringer responded to our request but declined to comment on its plans mAbbvie produces Humira (adalimumab)oving forward with the product, including a targeted launch date.

Without Competition, Expect 45% Jump in WAC Price 

As addressed earlier in this space, the time to effective competition for a US biosimilar adalimumab is crucial. Abbvie’s annual global revenue on the product may reach as much as $21 billion, with the last price increase registered in January, at 9.7%. Assuming Abbvie sticks to its pledge of no more than one

10% price increase per year, that would result in a wholesale acquisition cost (WAC) of more than $52,000 at the close of 2022, or a 45% jump from today’s WAC. This figure does not reflect individual negotiated rates (including rebates) that health plans and insurers actually pay. Yet, it does roughly indicate what type of discount will be necessary when biosimilars reach the market to simply attain the cost paid in 2018—that is, no more savings. Without competition before 2023, this may be the one area where payers pray for a rapid and bracing race to the bottom on price once 2023 rolls around. With Abbvie’s hand continuing on the tiller, don’t plan on it.

In other biosimilar news…Celltrion acknowledged that it is seeking to rectify the manufacturing plant issues that torpedoed its FDA approval of biosimilars for trastuzumab and rituximab. In the statement, it noted, “Celltrion is confident that the issues raised by the FDA will be resolved in a timely manner.

We can confirm that the resubmission will be in-place relatively soon. Then, we are expecting approvals in 6 months after resubmission according to regulatory timeline.”
