Abstract:

Background: Acetylsalicylic acid, clopidogrel and cilostazol are well-established agents inhibiting the normal function of platelets with known advantages and limitations. The development of novel antiplatelet agents aims in providing equal or superior outcomes for patients and simultaneously minimize side effects.

Objective: The aim of this manuscript is to review the latest data on the use of novel antiplatelet agents in vascular patients.

Method: Based on our 2016 review, a further search in the English medical literature has yielded a number of publications on cangrelor, prasugrel, ticagrelor, vorapaxar and a number of other – still experimental – agents (Ir-6, UBO-QIC, W1, revacept and YM-254890).

Results: Recently published data have not altered the use and indications of cangrelor, prasugrel and vorapaxar; all of them now approved by both FDA and EMA. The EUCLID trial has recently provided valuable data on the clinical use of ticagrelor, although results regarding vascular patients and administration of ticagrelor are still under scrutiny. Vorapaxar remains the only novel antiplatelet that is approved for PAD. Randomized control trials that focus on vascular patients are necessary to establish the safety and efficacy of these novel agents. Despite their positive initial results, most novel experimental antiplatelets are still in early development, thus in pre-clinical or early clinical phases of their trials. Research on three novel antiplatelets is currently discontinued (atopaxar, darexaban and elinogrel).

Conclusion: Vorapaxar remains the only novel antiplatelet that is approved for PAD. Other novel antiplatelets demonstrate positive results, but further studies focused on vascular patients are necessary. Novel experimental antiplatelets are still in early phases of the clinical and preclinical studies.
