PURPOSE: To determine the bioavailability, safety, and tolerability of a single dose of oral docetaxel plus encequidar (oDox + E) and compare its pharmacokinetic exposure with current standard of care IV docetaxel. INTRODUCTION: Docetaxel is a taxane widely used as an anti-neoplastic agent. Due to low oral bioavailability secondary to gut P-glycoprotein (P-gp) efflux, its current use is limited to intravenous administration. Oral docetaxel may provide a less resource intensive, more convenient, and tolerable alternative...

BACKGROUND: The Ataxia Telangiectasia and Rad3-related (ATR) protein complex is an apical initiator of DNA damage response pathways. Several ATR inhibitors (ATRi) are in clinical development including berzosertib (formerly M6620, VX-970). Although clinical studies have examined plasma pharmacokinetics (PK) in humans, little is known regarding dose/exposure relationships and tissue distribution. To understand these concepts, we extensively characterized the PK of berzosertib in mouse plasma and tissues...

OBJECTIVE: BRCA1/2 are integral to the DNA repair mechanism and their germline pathogenic variants (gBRCA) result in a high risk for developing breast and ovarian cancer. Patients with gBRCA mutations showed increased sensitivity to DNA cross-linking agent but might have increased treatment-related toxicities. Thus, we hypothesized that gBRCA mutation ovarian cancer patients who underwent platinum-based chemotherapy might be at higher risk of developing chemotherapy-induced hematologic toxicity...
