Arena Pharmaceuticals Announces First Participant Randomized in Phase 2 Trial Evaluating Temanogrel in Coronary Microvascular Obstruction (cMVO)
Arena Pharmaceuticals has initiated a Phase 2 trial for IV temanogrel, targeting coronary microvascular obstruction (cMVO) in patients undergoing percutaneous coronary intervention (PCI). With no FDA-approved treatments for cMVO, this trial aims to evaluate the safety and efficacy of temanogrel. The trial will enroll 99 participants across multiple countries, with a primary endpoint assessing changes in Index of Microcirculatory Resistance. Phase 2 results are anticipated in the latter half of 2022, marking a significant step in Arena's Cardiovascular Portfolio.
- Initiation of Phase 2 trial for IV temanogrel is a significant advancement.
- Potential to address an unmet medical need for cMVO patients with no current FDA-approved treatments.
- Trial involves multiple countries, improving its visibility and reach.
- No guarantees of successful trial outcomes or FDA approval.
- Potential difficulties in patient enrollment due to competition.
Arena Pharmaceuticals, Inc. (Nasdaq: ARNA) today announced that the first participant has been randomized in a Phase 2 trial evaluating IV temanogrel, an investigational, peripherally acting, and selective 5-HT2A receptor inverse agonist, for the potential treatment of coronary microvascular obstruction (cMVO) in patients undergoing percutaneous coronary intervention (PCI).
"Despite aggressive treatment with dual anti-platelet therapies, approximately 40
The Phase 2, multi-center, randomized, placebo-controlled trial is being conducted in the US, Australia, Sweden, Netherlands, and UK, and will assess the safety, tolerability, and efficacy of two doses of intravenous temanogrel on cMVO in patients undergoing PCI. The primary endpoint is the change in Index of Microcirculatory Resistance (IMR) from baseline (prior to administration of study treatment) to post-PCI on day 1. The trial is expected to enroll 99 participants.
"The dosing of our first patient in the Phase 2 study for the potential treatment of cMVO is a significant advancement for Arena's Cardiovascular Portfolio," stated Paul Streck, MD Senior Vice President and Chief Medical Officer of Arena. "To date, we have seen pre-clinical and scientific validation supporting the rationale for studying the use of temanogrel in patients undergoing PCI to prevent cMVO. We expect the availability of the Phase 2 data during the second half of 2022."
About Coronary Microvascular Obstruction
Coronary microvascular obstruction (cMVO) is a condition characterized by the failure to achieve full myocardial or microcirculatory reperfusion despite resolution of epicardial coronary occlusion and flow by a percutaneous coronary intervention (PCI). PCI results in activation of platelets and release of serotonin (5-HT), which is thought to mediate platelet aggregation and vasoconstriction.
About Temanogrel
Temanogrel (APD791) is an investigational, peripherally acting, and selective 5-HT2A receptor inverse agonist discovered by Arena, and is designed to inhibit serotonin (5-HT)-mediated amplification of platelet aggregation and vasoconstriction.
In addition to cMVO, Temanogrel is being investigated for the treatment of Raynaud's Phenomenon secondary to Systemic Sclerosis.
Temanogrel is an investigational compound that is not approved for any use in any country.
