CLINICAL NEWS denosumab and 23.98 months with ZA (HR=0.98, 95% CI 0.85-1.14; p value for non-inferiority = 0.01). However, deno- sumab did not demonstrate superiority in delaying time to first SRE and delaying time to first-and-subsequent SREs (second- ary endpoints). Overall survival (OS) was comparable for denosumab and ZA (HR=0.90; 95% CI 0.70-1.16; p value for non-inferiority = 0.41). Median PFS was 10.7 months longer in the denosumab group than the ZA group (46.1 months [range = 34.3 months to not estimable] and 35.4 months [range = 30.2 months to not estimable]; HR=0.82 [95% CI 0.68- 0.99]; p=0.036). The most common AEs (occur- ring in ≥10% of patients) associated with denosumab were diarrhea (34%), nausea (32%), anemia (22%), back pain (21%), thrombocytopenia (19%), peripheral edema (17%), hypocalce- mia (16%), upper respiratory tract infection (15%), rash (14%), and headache (11%). Patients discontinued denosumab most commonly because of osteonecrosis of the jaw. This AE occurred more often in the denosum- ab group than in the ZA cohort (4.1% vs. 2.8%; p values not reported). The median treatment exposure was 16 months (range = 1-50 months) with denosumab and 15 months (range = 1-45 months) with ZA. Source: Amgen press release, January 5, 2018. IV Bag Shortage Making Flu Season Worse Supplies of intravenous (IV) saline and nutrient solutions were already tight before hurricanes hit Puerto Rico in September of last year and cut power to manufacturing plants. Now, as Puerto Rico continues its recovery efforts, the U.S. supply of IV bags used to deliver sterile solutions is dropping to crisis levels. An aggressive flu season has further hampered hospitals. “If we can’t support patients coming [into] emergency rooms who have the flu, more people are going to die,” predicts Deborah Pasko, PharmD, MHA, director of medication safety and qual- ity at the American Society of Health- System Pharmacists. “I see it as a crisis.” Hospital officials, pharmacists, and other staff have been devising alterna- tives and workarounds: substituting pills for IV-administered drugs when possible and changing dosing schedules or injecting drugs directly into a vein. They’ve also been changing some procedures, such as discontinuing IV bags as soon as possible and not starting ASHClinicalNews.org patients on IV drips during surgery until it’s certain they are needed. The FDA said it believes shortages will start to ease by spring 2018, but stressed “the production situation in Puerto Rico remains fragile.” Puerto Rico’s power grid is being slowly restored and the last of three Baxter International factories there that make saline bags and nutrient solutions was reconnected in December 2017.

FDA Approves Firstline Arsenic Trioxide for Acute Promyelocytic Leukemia The FDA approved arsenic trioxide in combination with the all-trans retinoic acid (ATRA) tretinoin for firstline treatment of adults with newly diagnosed, low-risk acute promyelocytic leukemia (APL) and t(15;17) or PML-RARA gene expression. The decision was based on a global safety database for arsenic trioxide, as well as results from a randomized, phase III trial that enrolled 156 patients between October 2007 and September 2010. Participants received ATRA plus arsenic trioxide (n=77; median age = 44.6 years; range = 19.1-70.2 years) or ATRA plus chemotherapy (n=79; IT TAKES BOLD ACTION TO REDUCE CANCER IN KENTUCKY MARKEY CANCER CENTER See how at ukhealthcare.com/lesscancer
