Arena Pharmaceuticals Presented Phase 1 Clinical Data for Ralinepag in Pulmonary Arterial Hypertension at the European Society of Cardiology
Data from these Phase 1 clinical studies indicate that the ralinepag XR tablet formulation offers improved pharmacokinetic (PK) performance over selexipag and its active metabolite, MRE-269, by providing an extended effective half-life (28-29 hrs) and maintaining low peak–trough fluctuation with oncedaily dosing.
"With an extended half-life and low peak-to-trough fluctuation, the ralinepag XR tablet closely approximates the PK profile of continuously infused IV-prostacyclin," said
Title: Relative bioavailability and pharmacokinetic (PK) performance of a ralinepag extended-release (XR) tablet oral formulation and the effect of food and gender in healthy human subjects
Abstract number: 3022
Ralinepag (APD811) is a next-generation, oral, selective potent, once-daily IP receptor agonist intended for the treatment of pulmonary arterial hypertension (PAH). Arena discovered and developed this drug candidate internally. Ralinepag's potency on vasodilation, inhibition of proliferation of vascular smooth muscle cells, and inhibition of platelet aggregation, combined with an extended half-life, support its application as a potentially best-in-class agent for the treatment of PAH.
Ralinepag is an investigational compound that is not approved for any use in any country.
In addition, Arena has several collaborations including

Such forward-looking statements include, without limitation, statements about the following: the opportunity and potential of etrasimod and ralinepag, including to improve the treatment of patients, to meet unmet medical needs, to deliver broad utility across a range of immune and inflammatory conditions, to be best-in-class, and, in the case of ralinepag, to approximate the pharmacokinetic advantages of continuously infused IV prostacyclin with the ease of a once-daily oral; the ongoing and planned clinical programs for ralinepag and etrasimod, including Arena's ability and timing to initiate, enroll, and complete trials and announce clinical data; and Arena's focus, goals, strategy, clinical programs and collaborations. For such statements, Arena claims the protection of the Private Securities Litigation Reform Act of 1995. Actual events or results may differ materially from Arena's expectations. Factors that could cause actual results to differ materially from the forward-looking statements include that clinical programs may not proceed at the time or in the manner expected or at all, as well as those factors disclosed in Arena's filings with the
