Why Dynavax Technologies Corporation Should Be on Your Watchlist

Share of Dynavax Technologies have struggled ever since the FDA rejected the company's experimental hepatitis B vaccine, Heplisav. With a new trial launched, the stock could be a compelling long-term investment opportunity.

May 8, 2014 at 6:30PM

Vaccines are one of the fastest growing segments of the health care industry, with the total value of the market expected to nearly triple by 2022. Investors looking for a way to capture some of this growth, however, are generally limited to large-cap pharmas that have extensive product lines outside of the vaccine market space. The prevailing issue is that new vaccines tend to be low-profit ventures, making it difficult for smaller companies to raise the funds necessary to develop and bring a new vaccine to market. Dynavax Technologies Corporation (NASDAQ:DVAX) is a prime example of these difficulties -- and opportunities -- in the growing vaccine market.

Dynavax is developing a hepatitis B vaccine called Heplisav that is expected to compete chiefly against GlaxoSmithKline's (NYSE:GSK) Engerix-B. And although a late-stage study for Heplisav showed that it was clinically superior to Engerix-B, the Food and Drug Administration rejected it last year based on deficiencies in the study's ability to detect rare but serious adverse events. The European Medicines Agency came to roughly the same conclusion this February, forcing Dynavax to withdraw its Marketing Authorization Application in Europe as well. To remedy this issue, Dynavax recently launched a new late-stage study, which is expected to wrap up in late 2015. 

With little on the horizon in terms of catalysts, it's not entirely surprising that Dynavax shares have moved lower since withdrawing Heplisav's European application. Yet I believe there are two good reasons to keep this stock on your long-term watchlist.

Reason No. 1
Investor focus is surely to remain squarely on Heplisav for the foreseeable future. That said, I think it represents a compelling value proposition that's worth checking out. Namely, Dynavax estimates that Heplisav's global peak sales could top $700 million per year. While not quite a blockbuster, that's still almost twice the value of Dynavax's current market cap.

So why are investors apparently ignoring this compelling value proposition? I believe there are two reasons. Firstly, we are looking at a potential two-year wait until the vaccine might gain a regulatory approval in the U.S. or Europe. Secondly, GlaxoSmithKline's vaccine has a fairly clean safety profile as far as vaccines go, so Heplisav's new trial data will be scrutinized in this light. In effect, Heplisav has little margin for error in terms of safety because there is an approved product for this indication that is effective across a wide range of patient populations.

Even so, Heplisav appears to be substantially more effective than Engerix-B in certain subpopulations considered "difficult to immunize." And it's worth noting that the newly initiated trial is taking this issue one step further by specifically looking at Heplisav's seroprotection rate in type II diabetics. As such, I am cautiously optimistic that Heplisav will eventually be approved for at least certain subpopulations. 

Reason No. 2
An overlooked aspect of Dynavax is its early stage clinical program that includes partnerships with GlaxoSmithKline for autoimmune disorders and AstraZeneca (NYSE:AZN) for asthma. What's key to note is that the collaboration with AstraZeneca for AZD1419, as a potential asthma treatment, appears to be going well. Specifically, Dynavax received a $5.4 million payment in the first quarter as part of an amended agreement that saw AstraZeneca take responsibility for developing the therapy in a midstage trial. In short, AstraZeneca apparently likes what they've seen so far. Looking ahead, Dynavax is entitled to milestone payments totaling $100 million as AZD1419 progresses in clinical trials, and royalty payments if the therapy is eventually approved.

Foolish wrap-up
Although Dynavax shares have struggled mightily over the past half year, I believe this stock holds a fair amount of potential over the long term. The company secured its near-term-financing needs with a secondary offering recently, giving Dynavax $177.7 million at the end of the first quarter. Given its cash burn rate of roughly $7.3 million per month, I estimate the company to have a cash runway of around two years, so a dilutive financing shouldn't be an immediate concern. And while the stock lacks any clear cut near-term catalysts, I don't think its present market cap of only $383 million adequately reflects the potential of the company's clinical pipeline or its partnerships with major pharmas. So, you may want to dig deeper into this underloved biotech.

1 Key Step to Get Rich

Our mission at The Motley Fool is to help the world invest better. Whether that’s helping people overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we can help.

Feb 1, 2016 at 4:54PM

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 fool.com.

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 www.fool.com/beginners, 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 www.fool.com/podcasts.

But wait, there's more

The book and the podcasts – both free ... both awesome – also come with an ongoing benefit. If you download the book, or if you enter your email address in the magical box at the podcasts page, you'll get ongoing market coverage sent straight to your inbox.

Investor Insights is valuable and enjoyable coverage of everything from macroeconomic events to investing strategies to our analyst's travels around the world to find the next big thing. Also free.

Get the book. Listen to a podcast. Sign up for Investor Insights. I'm not saying that any of those things will make you rich ... but Business Insider seems to think so.
