Development and testing of an alternative responder definition for EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI).

Objectives: Dryness, fatigue and joint/muscle pain are typically assessed in Sjögren's trials using European Alliance of Associations for Rheumatology Sjögren's Syndrome Patient Reported Index (ESSPRI). A Patient Acceptable Symptom State of <5 and a Minimal Clinically Important Improvement (MCII)/responder definition (RD) of ≥1 point or 15% on ESSPRI have previously been defined. This study explored alternative RDs to better discriminate between active treatment and placebo in trials.

Content Validity of Sjögren's Syndrome Symptom Diary and Functional Assessment of Chronic Illness Therapy-Fatigue in Patients with Sjögren's.

Introduction: Sjögren's Syndrome Symptom Diary (SSSD) and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) are patient-reported outcome (PRO) instruments assessing Sjögren's symptoms. Original SSSD items have demonstrated content validity, however qualitative evidence supporting the updated 'tiredness' item and two new supplementary items is lacking. Although well established and validated in other rheumatic diseases, there is no qualitative evidence supporting content validity of FACIT-F in Sjögren's.

Qualitative Research with Patients and Physicians to Assess Content Validity and Meaningful Change on ESSDAI and ESSPRI in Sjögren's.

Introduction: European Alliance of Associations for Rheumatology (EULAR) Sjögren's Syndrome Disease Activity Index (ESSDAI) is a clinician-reported outcome (ClinRO) instrument, assessing Sjögren's disease activity from the physician perspective. EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) is a patient-reported outcome (PRO) instrument, assessing patient-defined Sjögren's symptom severity. Both instruments are commonly used as clinical trial endpoints and have been psychometrically validated.

Objective: To compare health care resource utilization (HRU) and costs among commercially insured patients with nasal polyposis (NP) with and without recurrence after endoscopic sinus surgery (ESS).

Study Design: Retrospective matched cohort study.

Setting: Adults with initial ESS or an NP excision after a new NP diagnosis were identified in Optum's Clinformatics Data Mart Database (October 1, 2014-December 31, 2019).

Clinical and economic analysis of patients with acute myeloid leukemia by FLT3 status and midostaurin use at a Comprehensive Cancer Center.

Introduction: Identification of cytogenetic and molecular abnormalities has become vital for the appropriate treatment of acute myeloid leukemia (AML). One of the most common molecular alterations in AML is the constitutive activation by internal tandem duplication of FMS-like tyrosine kinase 3 (FLT3).

Methods: This observational, retrospective, cohort study at the Huntsman Cancer Institute (HCI) had two time periods: 1) a historical pre-midostaurin time period which consisted of the FLT3 mutated (FLT3m) and FLT3 wild type (FLT3wt) cohorts from January 1, 2007, to December 31, 2016, and 2) a post-midostaurin cohort which consisted of the FLT3 mutated midostaurin-user cohort (early mido) from May 01, 2017 to December 31, 2018.

Budget Impact of Dabrafenib and Trametinib in Combination as Adjuvant Treatment of BRAF V600E/K Mutation-Positive Melanoma from a U.S. Commercial Payer Perspective.

Background: Before the approval of dabrafenib and trametinib in combination, there were no approved therapies in the adjuvant setting that target the RAS/RAF/MEK/ERK pathway.

Objective: To evaluate the budget impact of dabrafenib and trametinib in combination for adjuvant treatment of patients with BRAF V600 mutation-positive resected Stage IIIA, IIIB, or IIIC melanoma from a U.S.

Cost-effectiveness of dabrafenib and trametinib in combination as adjuvant treatment of BRAF V600E/K mutation-positive melanoma from a US healthcare payer perspective.

The COMBI-AD trial demonstrated the efficacy and safety of dabrafenib and trametinib in combination vs placebo as adjuvant treatment of patients with BRAF V600E/K mutation-positive resected Stage IIIA (lymph node metastasis >1 mm), IIIB, or IIIC melanoma. This analysis evaluated the cost-effectiveness of dabrafenib and trametinib vs observation from a US healthcare payer perspective. This evaluation employed a non-homogeneous, semi-Markov, cohort model with health states for relapse-free survival (RFS), post-locoregional recurrence (LR), post-distant recurrence (DR) receiving first-line treatment, and post-DR receiving second-line treatment.

Targeted agents or immuno-oncology therapies as first-line therapy for BRAF-mutated metastatic melanoma: a real-world study.

Targeted therapy (TT) and immuno-oncology (IO) drugs are approved for patients with BRAF mutant metastatic melanoma (MM). We compared real-world outcomes for first-line (1L) TT versus 1L IO to evaluate optimal sequencing. Physicians-identified BRAF mutant MM patients initiating 1L TT or IO therapies and extracted treatment, disease and clinical outcomes including disease response which were compared between TT and IO and individual regimens.

Patient preferences for treatment of metastatic melanoma.

Aim: To investigate patient preferences for clinical attributes of first-line metastatic melanoma treatments.

Materials & Methods: A discrete-choice experiment and best-worst scaling exercise were used to assess relative preferences for treatment attributes.

Results: The 200 survey respondents had distinct preferences.

Tyrosine kinase inhibitor therapy treatment and discontinuation in patients with chronic myeloid leukemia in chronic phase in the United States: a clinical practice perspective.

Tyrosine kinase inhibitor (TKI) therapy discontinuation practice in patients with chronic myeloid leukemia chronic phase (CML-CP) was assessed in real-world practice prior to the release of recommendations on discontinuation. Data were collected from US oncologists/hematologists (through web-based physician survey and patient chart review) on TKI therapy discontinuation practice including monitoring, adequate response for discontinuation, relapse, and symptoms following discontinuation. From the physician survey, 34% of oncologists/hematologists attempted discontinuation, with two-thirds doing so outside of a trial.

Cost Effectiveness of Midostaurin in the Treatment of Newly Diagnosed FLT3-Mutated Acute Myeloid Leukemia in the United States.

Objectives: The aim of this study was to assess the cost effectiveness of midostaurin + cytarabine + daunorubicin (midostaurin arm) versus placebo + cytarabine + daunorubicin (placebo arm) in the treatment of adult patients with newly diagnosed FLT3-mutated acute myeloid leukemia (AML) who are eligible for standard cytarabine + daunorubicin chemotherapy, from a US third-party payer perspective.

Methods: A lifetime partitioned survival model with four health states (active disease, complete remission [CR], relapse, and death) was constructed. Efficacy inputs (time to CR or death, time to relapse or death, and overall survival) were estimated using data from the RATIFY trial (NCT00651261).

Stage III melanoma incidence and impact of transitioning to the 8th AJCC staging system: a US population-based study.

Aim: To estimate incidence of stage III melanoma using the American Joint Committee on Cancer (AJCC) staging, 7th and 8th edition.

Patients & Methods: The SEER US cancer registry was analyzed (2010-2014). AJCC7 stages were recorded in the data; AJCC8 stages were inferred.

Patterns of treatment and BRAF testing with immune checkpoint inhibitors and targeted therapy in patients with metastatic melanoma presumed to be BRAF positive.

Patients with BRAF V600 (BRAF) mutated metastatic melanoma are eligible for therapy with both immune checkpoint inhibitors and targeted therapies, making treatment choice a complex decision. The present study aimed to describe patterns of treatment with immunotherapy and targeted therapy and BRAF testing in patients with metastatic melanoma presumed to have BRAF mutations (BRAF+) in the years following the approval of the newer generation of immune checkpoint inhibitors and targeted therapies (2014-2016). Two large US commercial claims databases [Truven Health Analytics MarketScan and IQVIA Real-World Data Adjudicated Claims - USA (IQVIA RWD Adjudicated Claims - USA)] were used.

Postsurgical treatment landscape and economic burden of locoregional and distant recurrence in patients with operable nonmetastatic melanoma.

Surgery is the mainstay treatment for operable nonmetastatic melanoma, but recurrences are common and limit patients' survival. This study aimed to describe real-world patterns of treatment and recurrence in patients with melanoma and to quantify healthcare resource utilization (HRU) and costs associated with episodes of locoregional/distant recurrences. Adults with nonmetastatic melanoma who underwent melanoma lymph node surgery were identified from the Truven Health MarketScan database (1 January 2008 to 31 July 2017).

Burden of Infections Among Chronic Myeloid Leukemia Patients Receiving Dasatinib or Nilotinib: A Real-World Retrospective Healthcare Claims Study in the United States.

Introduction: Tyrosine kinase inhibitors (TKI) have been demonstrated to prolong survival in patients with chronic myeloid leukemia (CML). However, TKIs may be associated with an increased risk of infections. This study compared healthcare resource utilization (HRU) and costs among patients with CML receiving dasatinib or nilotinib, with a focus on infection-related economic outcomes.

Healthcare resource utilization in patients with metastatic melanoma receiving first-line therapy with dabrafenib + trametinib versus nivolumab or pembrolizumab monotherapy.

Objective: To compare healthcare resource utilization (HRU) between patients with metastatic melanoma (MM) initiated on first-line (1L) combination therapy with the BRAF inhibitor dabrafenib and the MEK inhibitor trametinib (D + T; oral) and those initiated on 1 L monotherapy with the anti-PD1 monoclonal antibodies nivolumab or pembrolizumab (N/P; intravenous).

Methods: Patients with melanoma initiated on D + T or N/P from Q1/2014 to Q2/2016 (defined as 1 L treatment for MM) were identified in the Truven MarketScan database. Entropy balancing was used to reweight the N/P cohort in order to make it comparable to the D + T cohort with respect to the mean and variance of baseline covariates.
