Here'south Why Alexion Plunged for the Second Sequent Session on Tuesday

September 4, 2019

Alexion Pharmaceuticals Inc. (ALXN) has had an abysmal run over just the last ii sessions. While Fri saw the biotech — known for developing Soliris, a treatment for singular hemolytic uremic syndrome (aHUS) and paroxysmal nocturnal hemoglobinuria (PNH) — become the S&P 500's 2nd-worst performer that session, the stock outdid itself during Tuesday's session by being the index's biggest decliner with a five.v% loss. The connected selloff came on the heels of last week's hostile move from a competitor regarding Alexion'due south Soliris patent.

There'due south no denying the biotech sector's volatility this year, as the SPDR Southward&P Pharmaceuticals ETF (XPH) — a bellwether for all U.South. biotech and pharmaceutical firms — is downwardly more than 17% over the terminal six months confronting the S&P 500'south iv.two% gain. Simply information technology's rare for whatever kind of stock to experience the losses that Alexion has over the concluding two sessions, which has investors extremely nervous about the visitor's time to come following the latest news.

Here'due south a closer look at Alexion's newest battle — and what it could mean for the firm moving forwards…

The News

Last calendar week, competitor Amgen Inc. (AMGN) challenged Alexion past asking the U.S. Patent and Trademark Office (USPTO) to review Alexion's patents on its blockbuster Soliris drug. The USPTO'southward Patent Trial and Entreatment Board (PTAB) said Friday information technology was launching a so-called inter partes review (IPR) of Soliris' patents, which volition forcefulness Alexion to defend its IP – specifically roofing the drug's main ingredient, conception and use to treat PNH. The review is expected to accept around a year to complete.

Amgen tanked ALXN stock almost instantaneously, as the move signifies that Amgen wants to invalidate Alexion's patents in order to proceeds an edge in the market place with its own biosimilar version of Soliris. It comes soon later Alexion secured an extension on Soliris'southward patent protection until 2027, a move that now seems unclear amongst a fresh claiming to its intellectual property. Co-ordinate to reports, Soliris's master patent is set up to expire in the U.S. in ii years.

How Investors Reacted Investors dragged shares five.five% lower on Tuesday to $95.eighteen, the everyman settlement since Dec. 24 when ALXN — every bit well as the rest of the stock market — bottomed at $93.94. Tuesday's performance followed Friday's 10.2% crash from $112.17 to $100.76, which at the time was the worst shut since Jan. 3. At Tuesday'southward $95.18 close, shares are officially down 2.ii% year-to-date from the Dec. 31 close of $97.36.

The Bigger Picture show

Although Friday was likely thought to be nothing more knee-wiggle panic selling, the fact that ALXN continued lower with another 5% loss Tuesday illustrates how the company may actually be at risk of losing its Soliris patent. If that happens, Alexion would too lose control over the lucrative market for rare blood and musculus diseases like aHUS and PNH.

That's considering Soliris is an enormous moneymaker for Alexion, making upwards a sizable chunk of the firm'due south overall sales. Final year, Alexion's total sales across all products grew more than 16% to $4.xiii billion. Sales of Soliris climbed 13% to $three.56 billion, making up an insane 86.2% of the company'southward total revenue. And although sales of Alexion's other flagship drugs like Strensiq and Kanuma saw annual growth of 40% in 2018, their combined sales of $567.1 one thousand thousand don't concur a candle to Soliris'southward garganutan figure.

Looking Ahead

It's tough to prognosticate whether or not Amgen — whose market cap of $123 billion makes information technology a forceful competitor to Alexion's $24 billion market cap — will succeed in stripping Alexion of its prized product'southward patent. However, investors besides seem to have read the 2018 earnings report and empathize that even the smallest chance of losing the sole rights to Soliris could financially devastate Alexion. That being said, investors should stay away from ALXN until the USPTO makes a determination.
