Key Points
XPO1/CRM1 is upregulated in a BCR-ABL1 kinase-dependent and -independent manner and negatively controls PP2A tumor suppressor activity. KPT-330 antagonizes survival of TKI-resistant Ph+ acute leukemias in vitro, in CML-BC animals, and in a CML-AP patient.
Optimal management of breakthrough cancer pain (BTCP) requires analgesics with a rapid onset of action, consistent efficacy, improved patient acceptability and tolerability and ease of use. Fentanyl pectin nasal spray (FPNS) incorporates a proprietary pectin-based gelling agent to enhance absorption and produce a faster onset of action and consistent plasma concentration. FPNS is indicated for the treatment of breakthrough pain in cancer patients who are tolerant to opioid therapy for their underlying persistent cancer pain. FPNS has been evaluated in clinical studies in patients with BTCP and shown to be effective, safe and well tolerated. In addition, FPNS has demonstrated high levels of patient satisfaction, convenience and ease of use. FPNS therefore represents an important addition to the treatment options for BTCP.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
