Subgroup Analyses Primary and important secondary efficacy outcomes were consistent across subgroups . A trend toward more pronounced efficacy with vorapaxar was observed for both the primary and important secondary end points in patients who were not treated with thienopyridine at randomization. Vorapaxar increased rates of bleeding generally in most subgroups . Patients with lower body weight who received vorapaxar experienced a higher threat of GUSTO moderate or heavy bleeding than did patients with higher body weight . The hazard of GUSTO moderate or severe bleeding in the vorapaxar group had not been increased in patients who were not receiving a thienopyridine at randomization, whereas the risk was increased in patients who were receiving a thienopyridine .Furthermore, the findings show that in the five sufferers with myeloproliferative disorders, TET2 defects preceded JAK2 mutations during the evolution of the disease. Needless to say, this finding does not formally rule out an alternative sequence of mutations in other individuals with myeloproliferative disorders. In Patients MPD01, MPD04, and MPD35, virtually all the colonies derived from mature and immature progenitors carried a TET2 mutation, indicating the dominance of the TET2-mutated clone at early stages of hematopoiesis . In Sufferers MPD05 and MPD20, most immature progenitor cells had been wild type, whereas older progenitor cells got a mutated TET2.
