What happened Shares of Catalyst Pharmaceuticals (NASDAQ: CPRX) were jumping 13.7% higher as of 3:01 p.m. EST on Monday. Investors reacted positively after Catalyst provided a corporate update earlier in the day that included a sneak peek at full-year 2019 net revenue for lead drug Firdapse and guidance for 2020. So what Catalyst estimates that full-year 2019 net revenue for Firdapse will be around $102 million, with fourth-quarter net revenue of around $30 million. Catalyst also said that it expects to report a cash stockpile of around $95 million as of the end of 2019 with no funded debt. This puts the company in a position where it won't have to raise additional cash in the near term. Image source: Getty Images. The company looks for strong growth in 2020. Catalyst provided guidance that projects full-year 2020 net product revenue for Firdapse in treating Lambert-Eaton myasthenic syndrome (LEMS) of between $135 million and $155 million. It also expects that research and development and sales, general, and administrative expenses for the year will be around $65 million based on generally accepted accounting principles (GAAP). In addition, Catalyst announced that its clinical study evaluating Firdapse in treating anti-MuSK antibody positive myasthenia gravis (MuSK-MG) has met its enrollment goals. CEO Patrick McEnany said that the company is on track to complete this study and report top-line data in the first half of 2020. He also stated that Catalyst is focusing "on expanding the possible use of Firdapse as a treatment for other indications, while at the same time we aim to broaden our entire product pipeline." Now what Catalyst's update was chock-full of good news. It's important to note, though, that the actual 2019 revenue numbers for Firdapse won't be available until the company reports its fourth-quarter results, which should happen by March 16. Not every pharmaceutical stock performs well during the first year after the launch of a lead product. However, Catalyst stock nearly doubled in 2019 and is off to a good start in 2020. Investors will want to closely watch the results from the drugmaker's MuSK-MG clinical study. Good news from this study should enable Catalyst to keep up its winning ways. 10 stocks we like better than Catalyst PharmaceuticalsWhen investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
