Acceptability of intramuscular injection of tranexamic acid in postpartum hemorrhage prevention.

Background: Newer research comparing routes of medication administration has extended beyond efficacy as a primary endpoint to incorporate patient preference. However, little is known about the preferences of pregnant women in terms of routes of medication administration, specifically with regards to hemorrhage prevention and control.

Objective: This study aimed to understand the preferences of pregnant women in terms of medical interventions to prevent hemorrhage at the time of delivery.

Intermittent MEK inhibition for the treatment of metastatic uveal melanoma.

Introduction: Uveal melanoma (UM) is associated with poor outcomes in the metastatic setting and harbors activating mutations resulting in upregulation of MAPK signaling in almost all cases. The efficacy of selumetinib, an oral allosteric inhibitor of MEK1/2, was limited when administered at a continual dosing schedule of 75 mg BID. Preclinical studies demonstrate that intermittent MEK inhibition reduces compensatory pathway activation and promotes T cell activation.

Adjuvant crizotinib in high-risk uveal melanoma following definitive therapy.

Introduction: Approximately 40% of patients with uveal melanoma (UM) will develop metastatic disease. Tumors measuring at least 12mm in basal diameter with a class 2 signature, as defined by a widely used gene expression-profiling test, are associated with significantly higher risk of metastasis, with a median time to recurrence of 32 months. No therapy has been shown to reduce this risk.

A Phase Ib Study of Sotrastaurin, a PKC Inhibitor, and Alpelisib, a PI3Kα Inhibitor, in Patients with Metastatic Uveal Melanoma.

Uveal melanoma (UM) is a rare subset of melanoma characterized by the presence of early initiating GNAQ/11 mutations, with downstream activation of the PKC, MAPK, and PI3Kα pathways. Activity has been observed with the PKC inhibitors sotrastaurin (AEB071) and darovasertib (IDE196) in patients with UM. Inhibition of the PI3K pathway enhances PKC inhibition in in vivo models.
