A Review of the Safety and Efficacy of Bexagliflozin for the Management of Type 2 Diabetes.

OBJECTIVE: To review the pharmacology of bexagliflozin in addition to its safety and efficacy from available clinical trials used for its approval, as well as available clinical evidence to date. DATA SOURCES: A search of the National Institutes of Health Clinical Trials Registry (http://www.clinicaltrials.gov) and PubMed database was performed from inception through June 1, 2023. STUDY SELECTION AND DATA EXTRACTION QUANTIFICATION: The following study designs were included: meta-analyses, systematic review, clinical trial, or observational study design. Abstracts and drug monographs were also reviewed. Narrative or scoping reviews were excluded. Only articles in the English language and those evaluating the pharmacology, pharmacokinetics, safety, or efficacy of bexaglifozin in humans were included. DATA SYNTHESIS: Bexagliflozin reduces hemoglobin A1c ~0.5% with similar reductions in systolic blood pressure and body weight to other SGLT2 inhibitors. No cardiovascular outcomes trial is published, nor ongoing at this time. Adverse effects are similar to other SGLT2 inhibitors (genital mycotic and urinary tract infections, increased urination) including a warning for lower extremity amputation similar to canagliflozin. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON TO EXISTING DRUGS: Although no cost-effectiveness data are available, statements from the manufacturer suggest a competitive price point. Given limited trial data, lower cost, if chosen, may create a temporary niche for bexagliflozin pending generic availability of other SGLT2 inhibitors. However, given lack of cardiovascular and renal outcome data, empagliflozin, dapagliflozin, or canagliflozin may be preferred. CONCLUSION: Bexagliflozin appears safe and effective as monotherapy and add-on pharmacological therapy for the treatment of T2D.

Pharmacist-driven continuous glucose monitoring in community and ambulatory care pharmacy practice: A scoping review.

BACKGROUND: Continuous glucose monitoring (CGM) devices improve clinical outcomes and facilitate achieving patient-specific goals. However, opportunities and barriers to implementation of pharmacist-driven CGM services are not well-described. OBJECTIVES: This scoping review was conducted to identify opportunities and barriers to implementing pharmacist-driven CGM services in the community and ambulatory care setting. Clinical outcomes resulting from pharmacist-driven CGM were also explored. METHODS: A health librarian searched Ovid MEDLINE, Cochrane CENTRAL, Embase, Web of Science, Scopus, International Pharmaceutical Abstracts using keywords and subject headings from inception through December 2, 2022 to identify studies describing pharmacist or pharmacy-based CGM programs. No publication type, date limits, language restrictions, or other filters were applied. The database search was supplemented by a search of Google Scholar and a citation search of preselected gold standard articles. RESULTS: The scoping review initially identified 942 citations of which 249 passed abstract screening and 11 were included in the review. Among studies, the most common design was retrospective, populations varied, control groups were not consistently used, follow-up was primarily short, and sample sizes were small. One study evaluated pharmacist-driven CGM in a community pharmacy setting. Ten studies took place in the ambulatory care setting. Barriers to initiating pharmacist-driven CGM as a clinical service include educational, logistical, workflow, and financial incentive. Beneficial outcomes from pharmacist-driven CGM include improved quality of life, increased empowerment, and improved glycemic control. CONCLUSION: There is lack of strong evidence to support pharmacist-driven CGM in the community pharmacy setting. However, small studies suggest pharmacist-driven CGM is feasible and beneficial in the ambulatory care setting. Further exploration of how educational, logistical, workflow, and financial barriers can be overcome is warranted, given potential for improved clinical outcomes.

Impact of Overbasalization on Clinical Outcomes in Patients With Type 2 Diabetes: A Post Hoc Analysis of a Large Randomized Controlled Trial.

The American Diabetes Association's Standards of Medical Care in Diabetes emphasize the need for awareness regarding overbasalization (basal insulin doses >0.5 units/kg/day without bolus insulin) in the treatment of type 2 diabetes. However, outcomes data on the impact of overbasalization are limited. This post hoc analysis of a large randomized controlled trial suggests that an insulin therapy regimen involving overbasalization compared with a basal-bolus insulin regimen that avoids overbasalization is less effective at lowering A1C and may be associated with increased cardiovascular risk. Clinicians should consider alternative approaches to glycemic control before increasing basal insulin doses to >0.5 units/kg/day.

Measurement of Pharmacist-Physician Collaborative Care on Therapeutic Inertia in Patients With Type 2 Diabetes.

BACKGROUND: Team-based care practice models have been shown to improve diabetes-related therapeutic inertia, yet the method and type of antidiabetic treatment intensification (TI) leading to improvements in glycemic control are not well understood. OBJECTIVE: To evaluate time to TI in a pharmacist-physician practice model (PPM) as compared with usual medical care (UMC), explore the method and type of antidiabetic TI, and evaluate achievement of hemoglobin A1C (A1C) goal among each cohort. METHODS: This was a retrospective cohort study conducted between January 1, 2017, and December 31, 2018. Median time to TI was calculated and compared between patients in the PPM and UMC groups using the log rank test. Descriptive statistics were used to evaluate the method and type of TI and A1C goal achievement. RESULTS: A total of 56 patients were included. The median (interquartile range) time to antidiabetic TI among the PPM cohort was 37.5 days (8, 216.5), as compared with 142 days (16, 465) in the UMC cohort (P = 0.19). At 1 year post-index date, 25% of patients in the PPM cohort reached their A1C goal compared with 18.8% of patients in the UMC cohort. This effect was maintained in the subgroup (n = 49) of patients receiving TI (23.1% vs 17.8%). CONCLUSION AND RELEVANCE: A shorter time to TI and improvement in A1C goal achievement was observed with pharmacist-physician care compared with UMC. These findings suggest that pharmacist-physician care may be one of several interventions necessary to overcome therapeutic inertia in diabetes care.

Quality Improvement Success Stories are published by the American Diabetes Association in collaboration with the American College of Physicians and the National Diabetes Education Program. This series is intended to highlight best practices and strategies from programs and clinics that have successfully improved the quality of care for people with diabetes or related conditions. Each article in the series is reviewed and follows a standard format developed by the editors of Clinical Diabetes. The following article describes a pharmacist-physician collaborative effort to reduce A1C and blood pressure and thereby lower risks for complications for people with diabetes being treated at a network of family care clinics in the Tampa, FL, area.

Effect of Antidepressants on Glucagon-Like Peptide-1 Receptor Agonist-Related Weight Loss.

Background: Depression and obesity have a bidirectional relationship making the management of one, without the other, problematic. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are a preferred medication class for diabetes and obesity treatment given their weight loss effect; however, it is not known how antidepressants impact this effect. Objective: To assess the impact of antidepressant use on GLP-1 RA-associated weight loss in patients with or without type 2 diabetes mellitus. Methods: This was a retrospective, propensity matched, cohort study conducted using TriNetX. The study identified patients initiating a GLP-1 RA being treated with citalopram/escitalopram, bupropion, or no antidepressant. Cohorts were propensity score matched to analyze the primary outcome of mean end-of-study (77-371 days) body weight. Results: An initial query identified 31 273 patients eligible for analysis (30 160 receiving no antidepressant, 311 receiving bupropion, and 802 receiving citalopram/escitalopram). After propensity score matching, the study found patients receiving citalopram/escitalopram were taking more antidiabetic therapies at baseline compared with patients not treated with an antidepressant. Patients in the antidepressant cohorts experienced less weight loss compared with their respective matched cohorts not receiving antidepressants (citalopram/escitalopram -0.73 kg versus -1.74 kg; bupropion -0.84 kg versus -3.46 kg). Only the bupropion cohort was significantly heavier at end-of-study versus the non-antidepressant cohort (108 kg versus 103 kg, P = 0.018). Conclusion and Relevance: Antidepressants may diminish the weight loss effect of GLP-1 RAs. Additional research is needed to assess whether all GLP-1 RAs are affected similarly and the optimal weight loss strategies in patients receiving antidiabetic therapy with comorbid depression.

Anticipatory guidance and systematic review of prescribing combination incretin therapy in the treatment of type 2 diabetes.

WHAT IS KNOWN AND OBJECTIVE: Few studies have evaluated the efficacy and safety of combining a glucagon-like peptide-1 receptor agonist and dipeptidyl peptidase-4 inhibitor in patients with type 2 diabetes mellitus. Clinicians may frequently encounter this drug therapy combination in practice and should be aware of clinical evidence and risks associated with its use. METHODS: A literature search was conducted in Embase (1947-April 20, 2020), Medline - Ovid (1946-April 21, 2020), Medline - PubMed (1946-April 21, 2020), Cochrane Library CENTRAL Register of Controlled Trials (1991-April 20, 2020) and Web of Science (1900-April 17, 2020). Databases were searched using keywords and subject headings to identify studies assessing efficacy and safety of combination incretin therapy. The search identified 1255 studies. Of these, 383 were excluded for duplicate citations. Articles were then excluded based on title and abstract screen. RESULTS AND DISCUSSION: Six studies were included. A small reduction in haemoglobin A1c and weight loss was found by combining incretin therapy. Adverse effects such as hypoglycaemia, gastrointestinal upset and pancreatitis were infrequent. WHAT IS NEW AND CONCLUSION: On current evidence, the small benefit in glycaemic control that may be realized by using combination incretin therapy is unlikely to be offset by the potential increased risk of pancreatitis or additional cost. Additional long-term prospectively designed studies are needed to better understand the efficacy and safety of combination incretin therapy.

Prevalence of and Characteristics Associated With Overbasalization Among Patients With Type 2 Diabetes Using Basal Insulin: A Cross-Sectional Study.

This article describes a cross-sectional analysis of 655 patients to determine the prevalence of and patient-specific characteristics associated with overbasalization in patients with type 2 diabetes. Overbasalization was defined as uncontrolled A1C (>8%) plus a basal insulin dose >0.5 units/kg/day. The period prevalence of overbasalization was found to be 38.1, 42.7, and 42% for those with an A1C >8, ≥9, and ≥10%, respectively. Those with an A1C ≥9% had the greatest likelihood of experiencing overbasalization. These results suggest that overbasalization may play a role in patients not achieving optimal glycemic control in type 2 diabetes.

Oral Semaglutide: First-in-Class Oral GLP-1 Receptor Agonist for the Treatment of Type 2 Diabetes Mellitus.

Objective:The purpose of this article is to review the pharmacological characteristics and clinical evidence of oral semaglutide for the treatment of type 2 diabetes mellitus (T2DM). Data Sources: A MEDLINE/PubMed search was conducted between January 1, 2005, and September 30, 2019. Search terms included semaglutide, glucagon-like peptide 1 receptor agonist, GLP-1 receptor agonist, and type 2 diabetes. Study Selection and Data Extraction Quantification: The following study designs were included in the analysis: systematic review and/or meta-analyses, clinical trial, or observational study design. Narrative reviews were excluded. Articles were included only if they were published in the English language or evaluated oral semaglutide with regard to pharmacology, pharmacokinetics, safety, and efficacy in humans. Data Synthesis: Oral semaglutide has been Food and Drug Administration approved for the treatment of T2DM as an adjunct to diet and exercise. Oral semaglutide has been shown to result in an absolute hemoglobin A1C reduction between -0.5% and -1.5% and weight reductions between -1 and -4.7 kg. Oral semaglutide has been shown to be noninferior to placebo for cardiovascular (CV) safety although additional CV outcomes trials are ongoing. Adverse effects appear to be similar to those of other glucagon-like peptide-1 receptor agonists and are gastrointestinal in nature. Relevance to Patient Care and Clinical Practice: Oral semaglutide may be appropriate as second- or third-line add-on therapy for patients with T2DM who are not meeting treatment goals on metformin and are overweight and reluctant to use an injectable drug. Conclusions: Oral semaglutide appears safe and effective as monotherapy and add-on pharmacological therapy for the treatment of T2DM.

Using an Advanced Practice Pharmacist in a Team-Based Care Model to Decrease Time to Hemoglobin A1c Goal Among Patients With Type 2 Diabetes, Florida, 2017-2019.

Collaborative practice models that use an advanced practice pharmacist (APP) have been shown to improve outcomes for patients with chronic diseases. Few studies have evaluated the effects of team-based practice models involving an APP for time needed to attain glycated hemoglobin A1c (HbA1c) goals in patients with diabetes mellitus (type 2 diabetes). Ours is a retrospective cohort study, involving patients with type 2 diabetes who worked with a pharmacist in an academic family medicine clinic. These patients experienced a shorter time to achieve an HbA1c of less than 7%, as compared with patients who did not work with a pharmacist. Future studies should evaluate the length of time patients can sustain an HbA1c of less than 7% with team-based care involving an APP and the influence of such care on diabetes-related complications.

Evaluation of FDA Boxed Warning on Prescribing Patterns of Fluoroquinolones for Uncomplicated Urinary Tract Infections.

Background: Little is known regarding the impact of the Food and Drug Administration (FDA) boxed warning on prescribing rates of fluoroquinolone (FQ) antibiotics in the outpatient setting. Objective: The primary objective of this study was to evaluate the 2016 FDA boxed warning update on FQ prescribing rates for uncomplicated urinary tract infection (uUTI). Methods: This was a single-center retrospective cohort study conducted at 6 family medicine practices, including women aged 18 to 65 years with an outpatient visit for uUTI from January 1, 2016, to December 31, 2016. Results: A total of 436 patients met inclusion. FQs were prescribed in 38% of patients before the FDA boxed warning and in 30% of patients after (8% reduction). Non-FQ prescribing had a corresponding 8% increase, comprising 62% of uUTI prescribing before the FDA boxed warning and 70% after (P = 0.08). The likelihood of being prescribed a FQ was not significantly different following release of the FDA boxed warning (adjusted odds ratio = 0.67 [95% CI = 0.41-1.10]). Variables significantly associated with an increase in FQ prescribing based on logistic regression were age ≥58 years and chronic kidney disease. Concordance of antibiotic prescribing with the Infectious Diseases Society of America clinical practice guidelines for uUTI was low, and the incidence of treatment failure was low. Conclusion and Relevance: The 2016 FDA boxed warning was not significantly associated with decreased FQ prescribing for uUTI across a large academic family medicine practice. Methods to improve education and disseminate FDA warnings in practice are needed.

Impact of pharmacist care provision in value-based care settings: How are we measuring value-added services?

OBJECTIVES: To discuss the current state of measuring value-added services in emerging value-based payment practice models and their impact on the pharmacy profession. SUMMARY: Value-based care models require a focus on population health. In value-based care settings, providers are held accountable for risk that goes beyond the clinic encounter, and payment is tied to quality measures that reflect clinical and humanistic outcomes across the health care spectrum. This creates opportunities for pharmacist integration into value-based care settings through addressing gaps in care, optimizing medication use, and developing physician-pharmacist team-based care practice models. CONCLUSION: Scalable and sustainable pharmacist integration into value-based care settings should involve expansion of preventive care into the community. The need for measurement of the value added by pharmacy services is a priority.

Undetectable Vancomycin Concentrations Utilizing a Particle Enhanced Turbidimetric Inhibition Immunoassay in a Patient with an Elevated IgM Level.

BACKGROUND: A case of undetectable vancomycin concentrations with the use of a particle enhanced turbidimetric inhibition immunoassay is reported. METHODS: A 73-year-old woman with B-cell lymphoma, chronic neutropenia with myelodysplastic syndrome and elevated IgM levels displayed repeated undetectable vancomycin concentrations, despite appropriate empiric vancomycin dosing. The vancomycin concentrations were processed utilizing a particle enhanced turbidimetric inhibition immunoassay (PETINIA). Patients with high concentrations of paraproteins in their serum may have interference with the PETINIA. This may include patients with plasma cell dyscrasias and lymphoreticular malignancies associated with abnormal immunoglobulin synthesis. RESULTS: Repeated undetectable vancomycin drug concentrations prompted us to send a serum sample to an outside facility to utilize another standardized assay, enzyme multiplied immunoassay (EMIT), which resulted in a detectable vancomycin serum concentration. The patient's undetectable vancomycin drug concentrations with the PETINIA may have been due to abnormal immunoglobulin synthesis interference with the assay. A limited number of case reports have been published demonstrating undetectable or unexpectedly elevated vancomycin concentrations due to monoclonal immunoglobulin interference in patients with immunological disorders. CONCLUSIONS: A 73-year-old woman with B-cell lymphoma, chronic neutropenia with myelodysplastic syndrome and elevated IgM levels may have had interference with a PETINIA resulting in undetectable vancomycin concentrations.
