e18016 Background: The use of targeted oral cancer medications has increased significantly since 2001. Everolimus, an mTOR inhibitor was first approved for cancer treatment by FDA as second line for patients with advanced renal cancer. Subsequently it has been approved for advanced pancreatic neuroendocrine tumor (NET) in 2011 and breast cancer in 2012 respectively. Off-label use is common in oncology practice. The objective of this study is to assess prescription trends, especially off-label use of everolimus, among non-elderly cancer patients with private insurance in the United States from 2009 to 2014. Methods: Data from the MarketScan database were analyzed. Between 2009 to 2014, 4,728 cancer patients with at least one everolimus prescription were included in the analyses. The diagnosis which incurred the most recently to the initial everolimus use in each calendar year was recorded. Off-label use was defined as using everolimus by all of the cancer types except of renal cancer in 2009-2014, NET in 2011-2014 and breast cancer in 2012-2014. Results: The number of patients received everolimus has increased significantly from 243 in 2009 to 1,194 in 2014. The most common diagnoses associated with everolimus use were breast cancer (42%), followed by renal cancer (24%), and NET (7%). Off-label use of everolimus increased from 29% in 2009 to 47% in 2011 then decreased to 23% in 2014. The 3 most common diagnoses associated with off-label use of everolimus were secondary malignancies (30.7%), breast cancer (10.4%) and liver cancer (5%) in 2009-2011, compared to secondary malignancies (47.3%), brain cancer (4.2%) and lung cancer (3.9%) in 2012-2014. The off-label use in female has decreased significantly from 32% in 2009 to 19% in 2014 (p = 0.03). There was no statistical difference in off-label use of everolimus by geographic region. Conclusions: Analyses of MarketScan data suggest off-label use of everolimus is common among US cancer patients, especially in lung, liver and brain cancer and secondary malignancies after the approved indication was expanded to breast cancer in 2012. Further research of the factors associated with off-label use of everolimus and its economic implication is needed.

Background. Gonadotropin-releasing hormone (GnRH) agonists are FDA approved for the treatment of precocious puberty. The therapy consists of histrelin acetate (Supprelin), a surgically implanted device, or Lupron injections. In recent years, the use of these agents has been extended to include the off-label treatment of children with normally timed puberty. Trends in the off-label use of GnRH agonists in children across the U.S. have not been previously described in the literature. Methods. We analyzed data on the use of Supprelin and Lupron reported to the Pediatric Health Information System (PHIS) from 2013 to 2016 to determine the trends in both the FDA–approved and off-label uses of these medications. Results. We identified a stable cohort of 39 children’s hospitals administering GnRH agonist therapies from 2013 to 2016. During this period, the annual number of children treated with these medications for precocious puberty increased modestly, from 283 to 303; meanwhile, the fraction of children receiving therapy for an off-label indication more than doubled, from 12% (39 of 322 total patients) to 29% (125 of 428 total patients). Privately insured patients were more likely to be treated for an off-label indication (13%; 119 out of 883 patients) than Medicaid patients (8%; 58 out of 706 patients; χ2[1] = 10.97, P = .00093). Conclusion. From 2013 to 2016, the proportion of children treated with GnRH agonists for an off-label indication notably increased. The number of children treated for precocious puberty modestly increased. Private insurance coverage was associated with higher rates of off-label use.

Magnesium sulfate (MgSO4) is the agent most commonly used for treatment of eclampsia and prevention of eclampsia in patients with severe pre-eclampsia. Another commonly practiced offlabel use of this drug is in preventing preterm labor in pregnant women where the duration of the treatment might be more than one week. It is usually given either by intramuscular or intravenous route. After administration, about 40% of plasma magnesium is bound with protein. The unbound magnesium ion diffuses into the extravascular extracellular space and then diffuses into bone. It also crosses the placenta and fetal membranes and then diffuses into the fetus and amniotic fluid. Magnesium is almost exclusively excreted in the urine; 90% of the dose is excreted during the first 24 hours after an intravenous infusion of MgSO4. The clinical effect and toxicity of MgSO4 can be linked to its concentration in plasma. A concentration of 1.8–3.0 mmol/L has been suggested for treatment of eclampsia. The actual magnesium dose and concentration needed for prophylaxis have never been estimated. Maternal toxicity is rare when MgSO4 is carefully administered and monitored. Deep tendon reflexes, respiratory rate, urine output and serum concentrations are the most common variables for monitoring the toxic effect. Currently the United States (US) Food and Drug Administration (FDA) is advising health care professionals against using MgSO4 injection for more than 5–7 days to stop preterm labor in pregnant women (off-label use). Administration of MgSO4 injection to pregnant women for more than 5–7 days may lead to low calcium levels and bone problems in the fetus, including osteopenia and fractures. The harmful effect in the fetus with the shortest duration is not established. In light of this new safety information, the drug label for MgSO4 injection, USP 50% has also been changed, including changing the pregnancy category to D from A and denoting the effect as “New teratogenic effects”. Similarly, the manufacturers of other MgSO4 injection products have made similar changes to their drug labels. In this review, the currently available knowledge of the pharmacokinetics of MgSO4 and its clinical usage for women with pre-eclampsia and eclampsia, its off-label use and safety concern regarding the warning announced by the FDA will be outlined.

e18031 Background: Off-label drug use is common in cancer treatment (tx) due to limited approved tx options. Systematic analysis of RWD for off-label drug use facilitates hypothesis generation and design of clinical studies for new indications. Methods: We analyzed systemic tx data of > 145,000 cancer patients at Mount Sinai hospitals for 60 chemotherapy, 80 targeted, 16 hormonal therapy drugs, and 6 immune checkpoint inhibitors (CPIs). Off-label use was determined when patients received a drug for cancer indications that had not received regulatory approval, and the tx was not in a clinical trial setting. Clinical response to off-label tx was assessed using time to treatment discontinuation (TTD) as a surrogate endpoint. Results: Chemotherapy drugs were used off-label more frequently than targeted and hormonal agents. Across all cancer tx regimens involving a chemotherapy drug , 31% were off-label. In contrast, for tx regimens involving targeted and hormonal therapy drugs, only 11% and 6.7%, respectively, were used off-label. Further investigation revealed that chemotherapy often combines multiple drugs, where the combinations may include one or more drugs not approved for the disease. For example, cisplatin is approved only for bladder, ovarian and testicular cancers, but is widely used in combination to treat other cancers. Consequently, we observed an 84% off-label use of cisplatin. Several targeted drugs and CPIs were used off-label at high frequencies. 53% of nivolumab tx was off-label, primarily for treating hepatocellular carcinoma (before FDA approval) and relapsed/refractory multiple myelomas (RRMM). Trametinib targeting MEK and venetoclax targeting Bcl-2 were used off-label at a frequency of 84% and 89%, respectively, mainly in RRMM. In MM patients treated with trametinib (n = 91) and venetoclax (n = 121), 14 (15%) and 42 (35%), respectively, had TTD > 120 days. Conclusions: Off-label uses of novel targeted and immunotherapy drugs are likely based on disease mechanisms and when clinical trials deliver early, encouraging results. A thorough chart review would help us better understand clinical response as well as adverse events in these patients and potentially guide future clinical studies.

PURPOSE: To quantify early dissemination patterns, factors influencing use, and costs of bevacizumab (BEV) for the treatment of newly diagnosed ovarian cancer (OC) in the United States before its regulatory approval for this indication (off-label use). METHODS: We identified women 18-65 years of age with newly diagnosed OC treated with surgery and platinum-based chemotherapy from 2008 to 2016 through the MarketScan database (N = 8,109). The proportion of women receiving BEV over time was calculated, multivariate logistic regression used to determine factors associated with BEV use, and total costs per cycle of chemotherapy with and without BEV abstracted. RESULTS: BEV utilization rose 1.8-fold during the study period, from 4.1% (2008) to 7.4 % (2016). BEV was used with non–platinum/taxane regimens over a third of the time (37.2%). Physician specialty (medical oncology v gyn oncology) and geography (southeast region) were significantly associated with higher rates of use. Clinical factors associated with BEV use were metastatic disease and presence of ascites. The median cost of one cycle of platinum/taxane chemotherapy plus BEV was $10,897 in US dollars (USD) (interquartile range $7,573-$18,133 USD), compared with $1,629 USD (interquartile range, $683.0-$4,461 USD) for platinum/taxane alone. CONCLUSION: Off-label use of BEV for newly diagnosed OC was rare (< 10%), but doubled following presentation of phase II and III data at international meetings. Both clinical (ascites, metastatic disease, and age) and nonclinical (specialty and region) factors were associated with BEV use, and its use was accompanied by a six-fold increase in the cost of one cycle of treatment.
