Characteristics of Prior Authorization Policies for New Drugs in Medicare Part D.

This cross-sectional study examines the characteristics of prior authorization policies for new drugs in Medicare Part D to understand whether they are consistent with US Food and Drug Administration indications.

Variations in Use of Diabetes Drugs With Cardiovascular Benefits Among Medicaid Patients.

Importance: Cardiovascular death remains the leading cause of mortality in patients with type 2 diabetes (T2D). A better understanding of the current use and adoption of glucose-lowering drugs with cardiovascular benefit can inform state policies to ensure their appropriate use in patients with T2D. Objective: To characterize the use of glucose-lowering agents with known cardiovascular benefit over time and across states. Design, Setting, and Participants: This cross-sectional pharmacoepidemiological study of Medicaid prescription rates of glucose-lowering agents with known cardiovascular benefit vs those with less well-established cardiovascular benefit was conducted between 2014 and 2019. In 50 states and the District of Columbia, the study focused on nonmetformin, noninsulin glucose-lowering drugs divided into 3 cohorts: (1) sodium-glucose cotransporter 2 (SGLT2) inhibitors, (2) glucagon-like peptide 1 (GLP1) receptor agonists, and (3) all other classes of glucose-lowering drugs. Data were analyzed from January 2014 to December 2019. Main Outcomes and Measures: Number of days supplied of each cohort, use ratios between the aggregated days supplied of glucose-lowering agents with known cardiovascular benefit vs those with less well-established cardiovascular benefit, and the mean change in use ratios per quarter. Results: Across the 50 states and the District of Columbia, the use ratio of glucose-lowering agents with known cardiovascular benefit ranged from 1.58 to 0.14 (mean [SD], 0.48 [0.27]) in 2019. A lower use ratio was seen in states with a higher prevalence of diabetes (ß = -0.049; 95% CI, -0.086 to -0.012; P = .01), a larger total population (ß = -0.013; 95% CI, -0.023 to -0.003; P = .01), a greater number of Medicaid enrollees (ß = -0.054; 95% CI, -0.096 to -0.014; P = .01), a greater proportion of people enrolled in Medicaid (ß = -0.018; 95% CI, -0.030 to -0.007; P = .002), and a greater proportion of Medicaid patients enrolled in managed care organizations (ß = -0.0032; 95% CI, -0.0051 to -0.0013; P = .002). Higher Medicaid expenditures per enrollee (ß = 0.047; 95% CI, 0.007 to 0.089; P = .03) were associated with a higher use ratio of these agents. The relative use of glucose-lowering agents with known cardiovascular benefit by Medicaid enrollees increased 7.4% per year from 2014 to 2019, with wide variations across state Medicaid programs. Conclusions and Relevance: In this cross-sectional study, glucose-lowering agents with cardiovascular benefit increased in use during the study period, but also demonstrated considerable variation among states in their relative use. Medicaid programs should try to clarify which factors may be contributing to relative underuse of these potentially life-saving drugs.

Why Are Biosimilars Not Living up to Their Promise in the US?

Biologics are among the most expensive prescription drugs in the United States, posing significant barriers to patient access to necessary treatments. An abbreviated approval pathway for biosimilars, near-identical versions of biologics made by different manufacturers, was created by Congress in 2010 to stimulate competition in hopes of driving down costs and expanding access. However, as of February 2019, only 17 biosimilars have been approved, with only 7 currently on the market. Of the few biosimilars currently available to patients, overall utilization has been limited. This article examines the current landscape of the biosimilar market, characterizes tactics employed by biologics manufacturers to delay market entry and deter prescribing of biosimilars, and assesses ethical issues related to increasing the adoption of biosimilars.

Non-alcoholic fatty liver disease and colorectal cancer survival.

PURPOSE: Liver diseases including non-alcoholic fatty liver disease (NAFLD) and ensuing alterations to the micro-environment may affect development of liver metastasis. Mirroring the rise in obesity rates, prevalence of NAFLD is increasing globally. Our objective was to examine the association between NAFLD and mortality in colorectal cancer patients. METHODS: Colorectal Cancer-Sarcopenia and Near-term Survival (C-SCANS) is a retrospective cohort study which included 3,262 stage I-III patients, aged 18-80 years, and diagnosed between 2006 and 2011 at Kaiser Permanente Northern California. Cox proportional hazards regression was used to calculate multivariable adjusted hazard ratios (HR) and 95% confidence intervals (CI). RESULTS: After up to 10 years of follow-up, 879 deaths, including 451 from CRC were identified. Cases diagnosed with NAFLD before and within 1 month after CRC diagnosis (pre-existing NAFLD; n = 83) had a HR of 1.64 (95% CI 1.06-2.54) for overall and a HR of 1.85 (95% CI 1.03-3.30) for CRC-specific mortality compared to those without NAFLD. Findings did not differ significantly by sex, stage, tumor location, and smoking status, and were also similar when restricted to obese patients only. CONCLUSIONS: Independent of body mass index and prognostic indicators, CRC patients with pre-existing NAFLD had a worse prognosis than those without NAFLD.
