In an Oct. 3 research note, analyst Ed Arce reported the FDA approved two of Paratek Pharmaceuticals Inc.'s (PRTK:NASDAQ) therapies, Seysara and Nusyra, on Oct. 1 and Oct. 2, respectively.
As expected, Arce noted, Nusyra was approved as treatment for both community-acquired bacterial pneumonia and acute bacterial skin and skin structure infections (ABSSSI).
For both conditions, Nusyra may be given on an intravenous-to-oral basis, a 200 mg intravenous infusion first as a loading dose on day one, followed by 300 mg by mouth a day for seven to 14 days. The single intravenous administration is "an incremental positive" over the two to three days of infusion required in the pivotal trials, Arce pointed out.
For ABSSSI, an all-oral regimen is allowed, consisting of a loading dose of 450 mg once on the first and second days, followed by 300 mg per day. Because the dosing is all by mouth for this indication, Nusyra is more likely to be widely adopted.
In either indication, patients must fast for four hours before and two hours after taking a tablet, which Arce described as "one slight surprise to us."
Paratek intends to announce the price of Nusyra in Q4/18 and commercially launch the therapeutic in Q1/19. H.C. Wainwright estimates that sales of the drug will reach a peak of $1.75 billion.
The other drug, Seysara (saracycline), was approved for the treatment of inflammatory lesions resulting from non-nodular, moderate to severe acne vulgaris in 9-plus year olds, relayed Arce. Almirall, which owns the rights to Seysara, expects to commercially launch it in January 2019 and eventually reach peak annual sales of an estimated $150–200 million.
Paratek is entitled to receive from Almirall royalties on U.S. net sales, in addition to the $12 million approval milestone payment now due.
Arce reiterated his firm's Buy rating and $55 per share price target on Paratek. The target reflects more than fivebagger return potential, as the stock is currently trading at around $9.24 per share.[NLINSERT]
