Shares of cystic-fibrosis drugmaker Vertex Pharmaceuticals (NASDAQ: VRTX) fell 13% in October, according to data from
The entire industry took a beating last month, pushing the iShares Nasdaq Biotechnology index 11.5% lower. When Vertex Pharmaceuticals reported adjusted third-quarter earnings per share $0.02 below analyst estimates, a bad month for the stock became a little worse.
Overall, the stock's descent failed to reflect some pretty good results. Third-quarter sales of the company's flagship cystic fibrosis therapy, Kalydeco, rose 6% to $176 million despite saturation among its limited patient population. Revenue from the more recently launched Kalydeco-based combination therapy, Orkambi, jumped 79% over the prior-year period to $243 million.
Election results also bode well for Vertex Pharmaceuticals and drugmakers across the board. The defeat of Proposition 61, which would have created a potential model for lowering prescription-drug spending, and Republican control of Congress and the White House eased concerns about potential price controls going forward.
On a per-share GAAP basis, the $0.17 loss during the third quarter was much narrower than the $0.39 shortfall reported during the same period last year, and there are plenty of reasons to expect the trend toward profitability to continue. Perhaps the most obvious reason is the recent FDA approval for expansion of Orkambi's U.S. label to include patients aged 6 through 11 years old with two copies of the F508del mutation. This will expand the therapy's eligible U.S. population from about 8,500 to around 11,000.
More recently, Vertex announced success in a phase 3 trial designed to satisfy European regulators. If the application to include children aged 6 through 11 on Orkambi's EU label earns a widely expected approval, it will expand the therapy's addressable population in the region by another 3,400 patients.
While Orkambi expands to the largest group of cystic fibrosis patients, Vertex will continue its gargantuan effort to develop therapies to address all 2,000 known mutations associated with the disease. Along with third-quarter earnings, Vertex announced plans to begin separate clinical studies with two next-generation correctors, VX-440 and VX-152, in combination with Kalydeco and experimental tezacaftor.
The company expects data from both triple-combo studies in the second half of next year. In the meantime, investors will want to keep a close eye on Vertex's research and development budget. Unchecked R&D spending could pull the stock down even further. At the upper end of the company's guidance range for product sales and operating expenses, which includes R&D, it's expecting an operating profit around $465 million this year. Orkambi's recent expansions should give its top line some room to grow, but it is limited.
