2018 Is a Critical Year for These 3 Small Commercial-Stage Biotech Stocks

Making the leap from clinical-stage to the commercial-stage drug isn't easy. It requires an entirely different set of experience to navigate the world of private and public payers and a big investment in sales and marketing to convince doctors to prescribe drugs. In 2018, we'll find out if Keryx Pharmaceuticals (NASDAQ: KERX), Synergy Pharmaceuticals (NASDAQ: SGYP), and Flexion Therapeutics (NASDAQ: FLXN) have what it takes to succeed.

Expanding or not?

Keryx Pharmaceuticals didn't have a smooth time of it after it won FDA approval of Auryxia in 2014. Despite advantages over existing phosphorous binders that lower phosphorous levels in the body to increase calcium levels in chronic disease patients, sales have been slow to grow. Auryxia recorded only $27.2 million in revenue in 2016.

The drug's launch was hampered by manufacturing problems and breaking into a well-established market for binders that are delivered in dialysis centers, but it appears those problems are behind the company. In 2018, Keryx hopes Auryxia's newly approved indication as an anemia drug for non-dialysis patients will catapult revenue higher. Unquestionably, a lot is at stake because this is Keryx Pharmaceuticals' only drug.

There's some reason for optimism, given that the non-dialysis market opportunity is much bigger than the dialysis opportunity. Keryx Pharmaceuticals ability to spark sales growth this year (Auryxia's sales totaled $38.2 million through the first nine months) suggests that new insurance reimbursement is helping support prescription volume and physicians experience with Auryxia already could make it easier to convince them to prescribe Auryxia in its new indication.

Only time will tell if that's the case, but investors will be rooting for the company because a smooth launch in non-dialysis patients gives the company its best shot yet at achieving profitability. It's already posted a loss of $71 million so far this year.

Cutting in on the competition

Synergy Pharmaceuticals' Trulance is already sold in the U.S. for patients with chronic idiopathic constipation (CIC), but a pending FDA approval on Jan. 24 could clear its use in irritable bowel syndrome with constipation (IBS-C), too, and that could provide a big revenue tailwind in 2018.

Trulance won FDA approval in January 2017, but sales rang in at only $2.3 million in the second quarter. Prescription volume is growing, but the company faces stiff competition from Ironwood (NASDAQ: IRWD) and Allergan (NYSE: AGN) Linzess, which is already approved in both CIC and IBS-C. Last year, Linzess sales were $626 million, up 38% from 2015.
