Modeling health outcomes associated with BRCA testing and treatment strategies for patients with metastatic pancreatic cancer.

Background: Germline BRCA mutations (gBRCAm) occur in 4%-8% patients with metastatic pancreatic cancer (mPC); guidelines recommend platinum-based chemotherapies and olaparib maintenance in this population. We evaluated, through modeling, the role of treatments and gBRCA testing on health outcomes of mPC patients.

Methods: A decision tree/partitioned survival model was developed to assess lifetime health outcomes for four strategies: 1) no testing; 2) early testing/no olaparib maintenance; 3) early testing (i.

Patient-centered outcomes in the POLO study of active maintenance olaparib for germline BRCA-mutated metastatic pancreatic cancer.

Background: The phase 3 POLO study demonstrated a significant progression-free survival (PFS) benefit and preserved health-related quality of life (HRQOL) for active maintenance treatment with olaparib vs placebo in patients with metastatic pancreatic cancer and a germline BRCA mutation. Here, we present a post hoc analysis of the patient-centered outcomes: time without significant symptoms of disease progression or toxicity (TWiST) and quality-adjusted TWiST (Q-TWiST).

Methods: Patients were randomized 3:2 to maintenance olaparib (300 mg tablets twice daily) or placebo.

Adjuvant and neoadjuvant treatment patterns among resectable pancreatic cancer patients in the USA.

Chemotherapy is standard before and/or after pancreatic cancer resection, yet benefits of pre-resection chemotherapy are unclear. Real-world pre- and post-resection treatment patterns were evaluated retrospectively. Neoadjuvant (3-months pre-surgery) and adjuvant (6-months post-surgery) treatment claims from 1 January 2016 to 31 December 2019 in US adults with resectable pancreatic cancer were analyzed.

Health-Related Quality of Life of Patients with Metastatic Pancreatic Cancer: A Systematic Literature Review.

Background: Metastatic pancreatic cancer (mPaC) has a poor prognosis and available treatments provide only moderate improvements in survival. Preserving or improving health-related quality of life (HRQoL) is therefore an important treatment outcome for patients with mPaC. This systematic review identified HRQoL data in patients with mPaC before and after treatment, compared these with data from the general population, and reported the effects of different mPaC treatments on HRQoL.

Cost Effectiveness of Adding Pembrolizumab to Platinum and Fluoropyrimidine-Based Chemotherapy as First-Line Treatment for Advanced Esophageal Cancer: A US Healthcare Payer's Perspective.

Background And Objective: Pembrolizumab plus cisplatin and fluorouracil demonstrated superior efficacy and comparable safety compared with fluorouracil and cisplatin (FP) as first-line treatment for locally advanced unresectable or metastatic carcinoma of the esophagus and gastroesophageal junction adenocarcinoma in a phase III trial (KEYNOTE-590). This study evaluated the cost effectiveness of pembrolizumab plus FP versus FP and versus a blended chemotherapy comparator including FP, carboplatin plus paclitaxel, FOLFOX, FOLFIRI, docetaxel plus FP, trastuzumab plus FP, and trastuzumab plus FOLFOX from a US healthcare payer's perspective.

Methods: A partitioned survival model was developed with three health states (progression-free, progressive disease, and death).

Health-related quality of life scores of metastatic pancreatic cancer patients responsive to first line chemotherapy compared to newly derived EORTC QLQ-C30 reference values.

Background: Metastatic pancreatic cancer (mPC) and its treatments significantly impact health-related quality of life (HRQoL). POLO, a randomized, double-blind, placebo-controlled phase 3 trial evaluated the efficacy of olaparib as maintenance therapy in germline BRCA mutated mPC patients who had not progressed during ≥16 weeks of first-line platinum-based chemotherapy. HRQoL was assessed using the EORTC QLQ-C30.

Global longitudinal assessment of treatment outcomes in recurrent/metastatic nasopharyngeal carcinoma: GLANCE-NPC study.

Given a lack of standard of care treatment for recurrent/metastatic nasopharyngeal carcinoma (R/M NPC), we assessed treatment patterns and overall survival in the real-world setting. A retrospective chart review was conducted in patients who initiated first-line systemic therapy in Taiwan and South Korea between January 2012 and June 2013 with follow-up through December 2015. Among 154 R/M NPC patients, all patients in Taiwan (n = 104) had distant metastases, whereas in South Korea (n = 50) 42% had distant metastases.

Global treatment patterns and outcomes among patients with recurrent and/or metastatic head and neck squamous cell carcinoma: Results of the GLANCE H&N study.

Objectives: Given a lack of universally-accepted standard-of-care treatment for patients with recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC), study objectives were to assess treatment utilization and survival outcomes for R/M HNSCC in the real-world setting.

Materials And Methods: A multi-site retrospective chart review was conducted in Europe (Germany, United Kingdom, Italy, Spain), Asia Pacific (Australia, South Korea, Taiwan), and Latin/North America (Brazil and Canada) to identify patients who initiated first-line systemic therapy for R/M HNSCC between January 2011 and December 2013. Patients were followed through December 2015 to collect clinical characteristics, treatment and survival data.

Treatment patterns and outcomes among patients with recurrent/metastatic squamous cell carcinoma of the head and neck.

Aim: Cetuximab was approved in 2008 for treating recurrent/metastatic (R/M) head-and-neck squamous-cell carcinoma (HNSCC), and this study assessed the utilization of cetuximab for R/M-HNSCC in a real-world setting.

Materials & Methods: Adult patients with R/M-HNSCC, who initiated systemic therapy between 1 September 2011 and 31 December 2014 and followed through 31 December 2015, were identified from iKnowMed electronic-health-records database (McKesson Specialty Health) supplemented with manual chart-abstraction.

Results: For 325 R/M-HNSCC patients; median age 62 years; 82% males, 67% had oropharyngeal cancer, most common first-line (1L) regimen was platinum-based combinations (76%), of whom only 8% received platinum + cetuximab +/- 5-fluorouracil.

Effects of Achieving Target Measures in Rheumatoid Arthritis on Functional Status, Quality of Life, and Resource Utilization: Analysis of Clinical Practice Data.

Objective: To evaluate associations between achieving guideline-recommended targets of disease activity, defined by the Disease Activity Score in 28 joints using C-reactive protein level (DAS28-CRP) <2.6, the Simplified Disease Activity Index (SDAI) ≤3.3, or the Clinical Disease Activity Index (CDAI) ≤2.

Exposure to potential CYP450 pharmacokinetic drug-drug interactions among osteoarthritis patients: incremental risk of multiple prescriptions.

Patients taking more than one drug metabolized through the cytochrome P450 (CYP450) enzyme system experience a drug-drug exposure (DDE), which puts them at risk for a potential pharmacokinetic drug-drug interaction (DDI), defined as two or more drugs interacting in such a way that the effectiveness and/or toxicity of one or all drugs are changed. Any patient subjected to a DDE is at risk for a potentially serious DDI, the epidemiology of which has not been thoroughly studied. Many drugs are metabolized primarily via the CYP450 enzyme system, including certain opioids used to manage moderate to severe chronic pain.

Prevalence of exposure to potential CYP450 pharmacokinetic drug-drug interactions among patients with chronic low back pain taking opioids.

Drug-drug interactions (DDIs) have been defined as two or more drugs interacting in such a way that the effectiveness and/or toxicity of one or all drugs are changed. Patients taking more than one drug metabolized through the cytochrome P450 (CYP450) enzyme system, including some, but not all, opioids experience a drug-drug exposure (DDE), which may result in a potentially dangerous DDI. Using a retrospective analysis of a large commercial claims database and a Medicare database, we evaluated DDEs that have the potential to cause DDIs among chronic low back pain (cLBP) patients on long-term opioid analgesia, which metabolizes through the CYP450 enzyme system, concomitant with other CYP450-metabolized drug(s).
