Platelet P2Y inhibitors have a key role in reducing thrombotic complications in patients undergoing percutaneous coronary intervention (PCI) and those with acute coronary syndrome (ACS). Clopidogrel, prasugrel and ticagrelor are widely prescribed oral P2Y receptor antagonists, but numerous clinical and pharmacological factors can lead to impaired gastrointestinal absorption resulting in reduced antithrombotic protection. These observations underscore the need for novel compounds or routes of administration that enable more favorable pharmacokinetic and pharmacodynamic profiles while reducing the risk for thrombotic complications.
Selatogrel, formerly known as ACT-246475, is a novel, potent, reversible, and selective non-thienopyridine antagonist of the P2Y receptor developed for subcutaneous administration. Results from preclinical, Phase 1 and 2 studies have shown selatogrel to have rapid absorption and sustained and reversible platelet P2Y inhibitory effects with a larger therapeutic window compared to the oral P2Y inhibitors. Such findings make selatogrel a promising agent to be tested in phase 3 studies.
Advantages of subcutaneous administration of selatogrel are fast onset of action, easy administration and the fecal excretion not requiring dose adjustment based on renal function. These characteristics may translate into an advantage in the peri-procedural setting and in emergency and/or unconscious patients. Selatogrel may represent a viable alternative to intravenous P2Y inhibition (i.e. cangrelor), although some aspects need to be further clarified, including side effects, how to switch to oral P2Y inhibitor and the association with concomitant drugs.
血小板 P2Y 抑制剂在减少经皮冠状动脉介入治疗(PCI)和急性冠脉综合征(ACS)患者的血栓并发症方面发挥着关键作用。氯吡格雷、普拉格雷和替格瑞洛是广泛应用的口服 P2Y 受体拮抗剂,但许多临床和药理学因素可导致胃肠道吸收受损,从而降低抗血栓保护作用。这些观察结果强调需要新型化合物或给药途径,以实现更有利的药代动力学和药效学特征,同时降低血栓并发症的风险。
Selatogrel,前称 ACT-246475,是一种新型、强效、可逆、选择性的非噻吩吡啶 P2Y 受体拮抗剂,开发用于皮下给药。临床前、1 期和 2 期研究的结果表明,Selatogrel 具有快速吸收作用,以及持续和可逆的血小板 P2Y 抑制作用,与口服 P2Y 抑制剂相比,治疗窗更大。这些发现使 Selatogrel 成为一种有前途的药物,可在 3 期研究中进行测试。
Selatogrel 皮下给药的优势在于起效迅速、给药方便,且粪便排泄无需根据肾功能调整剂量。这些特征可能在围手术期、急救和/或无意识患者中具有优势。Selatogrel 可能是静脉内 P2Y 抑制(即坎格雷洛)的一种可行替代品,尽管还需要进一步澄清一些方面,包括副作用、如何转换为口服 P2Y 抑制剂以及与伴随药物的关联。
