PHAR investigators, in collaboration with Sanofi, conducted a commercial claims analysis of patients with relapsing-remitting multiple sclerosis (RRMS) who started treatment with teriflunomide using IQVIA PharMetrics® Plus data. Their study found that high adherence to disease-modifying therapies (DMTs) was associated with fewer relapses and lower healthcare utilization among patients with RRMS. As DMT adherence among RRMS patients is suboptimal, this work may inform decisions on selecting interventions to improve adherence, and therefore, patient outcomes.

PHAR Develops Expert Consensus on Potential Clinical Benefits from Early Cancer Detection
PHAR investigators, in partnership with GRAIL, convened a panel of 10 oncologists to develop clinical consensus on which cancers had the greatest likelihood of benefitting from advances in early diagnosis. Investigators used a formal, validated group consensus process that combines systematic literature review evidence and clinical expertise. Panelists were asked to rate current curability and benefit (improvement in curability) of an annual hypothetical multi-cancer screening blood test on 20 solid organ cancers, concluding most solid tumors have a likelihood of benefit from early detection.

PHAR Examines Clinical and Economic Burden of Hospitalizations for AL Amyloidosis
In collaboration with Prothena, PHAR’s Michael S. Broder, MD, MSHS, Eunice Chang, PhD, and Marian H. Tarbox, MPP published their analysis of costs for hospitalizations among patients with AL amyloidosis using a national database of hospital discharge data. Investigators found higher healthcare utilization and costs associated with patients with an in-hospital death compared with patients discharged alive, likely attributed to greater cardiac and renal involvement. Their research underscores the need for increased disease awareness and early diagnosis, which may lead to earlier treatment and reduced costs. The manuscript was published in the Journal of Comparative Effectiveness Research and can also be found on the PHAR Publications page.
Collaborator Tiffany Quock, PhD, MS gave an interview on the study and its findings with the Evidence Base as part of its Peak Behind the Paper feature, which can be read here.
PHAR Delphi Panel Estimates Utilization in Patients With Advanced Stage Amyloidosis
PHAR’s Sarah N. Gibbs, MPH, Irina Yermilov, MD, MPH, MS, and Michael Broder, MD, MSHS, conducted a Delphi panel to estimate healthcare utilization in patients with advanced AL amyloidosis at different points in the disease course. Their abstract was published in the November 2022 supplement issue of Blood, the official journal of the American Society of Hematology, and can also be found on the PHAR publications page.
PHAR Quantifies Benefits of Post-Approval R&D of New Medicines
In collaboration with the Pharmaceutical Research and Manufacturers of America (PhRMA), PHAR conducted a real-world analysis in order to calculate the benefits of R&D past initial FDA approval in a subset of previously approved drugs. The recently passed Inflation Reduction Act would allow the government to renegotiate prices for prescription medicines as early as 7 years post approval. PHAR and PhRMA’s study examines how this may impact R&D investment decisions for medicines by investigating the number and timing of additional FDA approvals for new uses or indications for new medicines initially approved by the FDA between 2010 and 2012, and calculating the share of post-approval indications that occurred 7 or more years after each drug’s initial FDA approval. The findings of their analysis speak to the potential impact of recently enacted government policies, which disincentivizes investment and further development of critical post-approval innovations.

PHAR Strengthens Validation of a Claims-Based Algorithm to Identify NMOSD
PHAR, in collaboration with Genentech, presented findings from further validation of their claims-based algorithm used to identify patients with neuromyelitis optica spectrum disorder (NMOSD), a disorder that can be difficult to distinguish from other demyelinating central nervous system (CNS) disorders in clinical practice.
Earlier this year, PHAR developed an algorithm to distinguish patients with NMOSD from patients with multiple sclerosis and other CNS inflammatory disorders, validating it in a proxy insurance claims database derived from billing and medication records from three neurology care centers. Interim results were presented at ACTRIMS Forum 2022. Since then, PHAR has further demonstrated the performance of the algorithm in a dataset of 101 patients from five neurology care clinics and has tested its face validity using 2016–2019 data from IBM® MarketScan® Commercial and Medicare Supplemental databases. Their poster was presented at the 38th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), and the abstract was published in the October supplement issue of Multiple Sclerosis Journal.
PHAR Reports Frequency, Costs of Hospital Admissions During Which AL Amyloidosis is Diagnosed
PHAR investigators, in collaboration with Prothena Biosciences Inc., conducted a retrospective analysis of nationally representative hospital discharge data estimating the frequency and costs associated with hospitalizations during which systemic amyloid light chain (AL) amyloidosis was diagnosed. This is the first analysis to use an AL amyloidosis specific ICD-10 diagnosis code in a nationally representative database to provide data on hospital admissions for this disease.
Eunice Chang, PhD, Katalin Bognar, PhD, Marian Tarbox, MPP, and Michael S. Broder, MD, MSHS found that diagnostic admissions are more likely to be urgent/emergent, require longer stays, and have higher costs compared with hospitalizations in known AL amyloidosis patients. The manuscript describing their findings was published in the December 2022 issue of Journal of Comparative Effectiveness Research and can be found on PHAR’s publications page.
PHAR Develops Expert Consensus on the Management of Infusion-Related Reactions Presenting With Pain in Patients Receiving Crizanlizumab
PHAR’s Irina Yermilov, MD, MPH, MS, Cynthia Campos, MPH, and Michael Broder, MD, MSHS, in collaboration with Novartis Pharmaceuticals, convened a RAND/UCLA modified Delphi panel of 10 clinicians to develop consensus on the management of infusion-related reactions presenting with pain in patients with sickle-cell disease receiving crizanlizumab. Their research and findings were orally presented at the 17th Annual Scientific Conference on Sickle Cell and Thalassaemia (ASCAT). The presentation can be viewed here, and the abstract will be published in a supplement issue of HemaSphere.
PHAR Publishes Systematic Review of the Economic and Humanistic Burden of Pediatric Onset Multiple Sclerosis
PHAR investigators Cynthia Campos, MPH, Hannah Dalglish, MPH, Sarah Gibbs, MPH, and Irina Yermilov, MD, MPH, MS, in collaboration with Sanofi, conducted a systematic literature review on the global economic (healthcare resource utilization and costs) and humanistic (quality of life) burden associated with pediatric onset multiple sclerosis (POMS). They identified and summarized 11 studies on healthcare resource utilization, cost, or insurance coverage, and 36 studies that reported quality-of-life outcomes in patients with POMS. Results demonstrated that healthcare resource utilization and costs are high in patients with POMS and patients reported reduced quality of life as well as significant fatigue compared to healthy children and adolescents. Their review was published in the Journal of Health Economics and Outcomes Research, and can also be found here.
PHAR Examines Mortality and Costs Associated With Influenza in Elderly Medicare Beneficiaries Treated vs Untreated With Antivirals
PHAR’s Sheila Reddy, PhD, MSc, RPh, Eunice Chang, PhD, Katalin Bognar, PhD, and Marian Tarbox, MPP, in collaboration with Genentech, Inc., identified antiviral treated and untreated patients ≥66 years old with an influenza diagnosis during flu seasons 2016-2018 in a retrospective study of Medicare Fee-For-Service claims from the 100% Research Identifiable Files. Results showed prompt antiviral treatment may be associated with reduced mortality, healthcare resource utilization, and economic burden in elderly Medicare beneficiaries with seasonal influenza. These findings were presented at AMCP Nexus; the poster can be viewed here, and the abstract was published in the October supplement issue of the Journal of Managed Care & Specialty Pharmacy.
