Better Buyout Candidate: Chelsea Therapeutics International Ltd. vs. InterMune Inc.

A Foolish look at two top buyout candidates in the health care sector.

Mar 17, 2014 at 2:30PM

As more key drugs come off of patent protection, one of the central themes in biotech this year is the buyout. Companies like AstraZeneca plc and Eli Lilly, that have been deeply stricken by the so-called patent cliff, will undoubtedly be on the lookout for new drugs or pipelines to compensate for falling revenue.

Fortunately, there are a fair number of smaller biotechs that could fill this need without breaking the bank. Chief among them, Chelsea Therapeutics (NASDAQ:CHTP) and InterMune, (NASDAQ:ITMN) have bubbled to the top of many buyout lists. So, with this idea in mind, let's consider which company offers potential suitors the best opportunity. 

Chelsea offers its orphan drug Northera
Last month, the U.S. Food and Drug Administration, or FDA, approved Chelsea's drug Northera as a treatment for dizziness stemming from symptomatic neurogenic orthostatic hypotension, or NOH. The good news is that this is the first approved treatment for NOH.

The bad news is that the potential market is fuzzy because: NOH is poorly diagnosed, the FDA is requiring a large postmarketing study, and Northera's label will contain a black box warning about the increased possibility of hypertension. So, while analysts have suggested Northera could see peak sales anywhere from $300 million to $450 million, numerous hurdles lie ahead.

Because of these issues, Chelsea is said to be actively seeking either a partner to help commercialize Northera, or a buyer for the entire company. If management can't find either, the current plan is to launch Northera sometime in the second half of 2014.

That said, I think Chelsea is wise to seek a buyout here. At the end of the day, it would have to raise significantly more capital than the $45 million on hand to transition into a commercial operation and pay for a postmarketing study. Launching new drugs is expensive in its own right, and doubly so for companies brand new to this part of the business.

Besides Northera, Chelsea offers potential suitors an experimental drug, CH-4051, for Rheumatoid Arthritis that is currently in a mid-stage trial. 

InterMune counters with its orphan drug Esbriet
InterMune reported top-line data from a pivotal late-stage trial for Esbriet last month, where the drug easily met its primary and secondary endpoints as a potential treatment for idiopathic pulmonary fibrosis, or IPF. Investors and patients alike rejoiced over this news because IPF is a fatal disease with no treatment options approved by the FDA. InterMune shares have now risen 117% on the back of this stellar news, and the buyout rumors have started to swirl. Consequently, InterMune's market cap has ballooned to $2.8 billion, meaning that a buyout wouldn't come cheap. 

Why is InterMune a buyout target? Put simply, Esbriet is an orphan drug that is expected to become a blockbuster. Goldman Sachs analyst Terence Flynn believes Esbriet will see peak sales of around $1.3 billion. Beyond Esbriet, however, InterMune doesn't have a lot to offer a potential suitor. So, a deal would center chiefly around Esbriet's commercial value. 

Foolish wrap up
While I am optimistic about the upside potential of both companies, I think InterMune is a more attractive buyout candidate at the present time. Esbriet has a clearly defined target market and had stronger clinical trial results than Northera.

Presently, there are too many unknowns surrounding Northera's commercialization to get a good feel for how Chelsea should be valued. And I think the stock's volatile trading pattern, since Northera's approval, reflects this high degree of uncertainty.

That said, I think Chelsea would garner a higher premium than InterMune in a buyout scenario. Chelsea appears to be trading at a deep discount even under a pessimistic scenario for Northera's commercial prospects, which is probably because the market is anticipating a large secondary offering. In sum, I wouldn't be surprised if both companies end up getting bought out, but InterMune is this Fool's pick in a head to head comparison.

To be perfectly clear, this is not a get-rich action that my Foolish colleagues and I came up with. But we wouldn't argue with the approach.

A 2015 Business Insider article titled, "11 websites to bookmark if you want to get rich" rated The Motley Fool as the #1 place online to get smarter about investing.

"The Motley Fool aims to build a strong investment community, which it does by providing a variety of resources: the website, books, a newspaper column, a radio [show], and [newsletters]," wrote (the clearly insightful and talented) money reporter Kathleen Elkins. "This site has something for every type of investor, from basic lessons for beginners to investing commentary on mutual funds, stock sectors, and value for the more advanced."

Our mission at The Motley Fool is to help the world invest better, so it's nice to receive that kind of recognition. It lets us know we're doing our job.

Whether that's helping the entirely uninitiated overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we want to provide our readers with a boost to the next step on their journey to financial independence.

Articles and beyond

As Business Insider wrote, there are a number of resources available from the Fool for investors of all levels and styles.

In addition to the dozens of free articles we publish every day on our website, I want to highlight two must-see spots in your tour of

For the beginning investor

Investing can seem like a Big Deal to those who have yet to buy their first stock. Many investment professionals try to infuse the conversation with jargon in order to deter individual investors from tackling it on their own (and to justify their often sky-high fees).

But the individual investor can beat the market. The real secret to investing is that it doesn't take tons of money, endless hours, or super-secret formulas that only experts possess.

That's why we created a best-selling guide that walks investors-to-be through everything they need to know to get started. And because we're so dedicated to our mission, we've made that available for free.

If you're just starting out (or want to help out someone who is), go to, drop in your email address, and you'll be able to instantly access the quick-read guide ... for free.

For the listener

Whether it's on the stationary exercise bike or during my daily commute, I spend a lot of time going nowhere. But I've found a way to make that time benefit me.

The Motley Fool offers five podcasts that I refer to as "binge-worthy financial information."

Motley Fool Money features a team of our analysts discussing the week's top business and investing stories, interviews, and an inside look at the stocks on our radar. It's also featured on several dozen radio stations across the country.

The hosts of Motley Fool Answers challenge the conventional wisdom on life's biggest financial issues to reveal what you really need to know to make smart money moves.

David Gardner, co-founder of The Motley Fool, is among the most respected and trusted sources on investing. And he's the host of Rule Breaker Investing, in which he shares his insights into today's most innovative and disruptive companies ... and how to profit from them.

Market Foolery is our daily look at stocks in the news, as well as the top business and investing stories.

And Industry Focus offers a deeper dive into a specific industry and the stories making headlines. Healthcare, technology, energy, consumer goods, and other industries take turns in the spotlight.

They're all informative, entertaining, and eminently listenable ... and I don't say that simply because the hosts all sit within a Nerf-gun shot of my desk. Rule Breaker Investing and Answers contain timeless advice, so you might want to go back to the beginning with those. The other three take their cues from the market, so you'll want to listen to the most recent first. All are available at
