The Value of Pharmaceutical Industry-Sponsored Patient Registries in Oncology Clinical Research.

In May 2019, the US Food and Drug Administration (FDA) released the Framework for FDA's Real-World Evidence (RWE) Program, a draft guidance to evaluate the potential use of real-world data in facilitating regulatory decisions. As a result, pharmaceutical companies and medical communities see patient registries, which are large, prospective, noninterventional cohort studies, as becoming increasingly important in providing evidence of treatment effectiveness and safety in clinical practice. Patient registries are designed to collect longitudinal clinical data on a broad population to address critical medical questions over time. With their large sample sizes and broad inclusion criteria, patient registries are often used to generate RWE in the general and underrepresented patient populations that are less likely to be studied in controlled clinical trials. Here, we describe the value of industry-sponsored patient registries in oncology/hematology settings to healthcare stakeholders, in drug development, and in fostering scientific collaboration.

Increasing colorectal cancer in the young population and tailoring of the colorectal cancer screening recommendations in subpopulation: a retrospective single-center study.

PURPOSE: The United States Preventive Services Task Force (USPSTF) newly drafted recommendations for colorectal cancer (CRC) screening age in average-risk individuals decreased to 45 years from 50 years. This study evaluates the change in the incidence of CRC, compares the demographic characteristics, characteristics of CRC, survival, and factors affecting the survival of younger (< 50 years) with the older (> 50 years) CRC-diagnosed population of Boston Medical Center (BMC). Also tailors the screening recommendations of CRC based on subpopulations. METHODS: A retrospective cohort study was conducted from 2004 to 2019 at BMC who underwent colonoscopy, to see newly diagnosed CRC. The analysis was done in R studio version 1.2.5033. RESULTS: The incidence rate of CRC is increasing in the younger population. The CRC in younger population was 350 and older was 2019. The most prevalent site among the younger population was rectum (33.33%), and most of the CRC were diagnosed at an advanced stage. Hispanics were less likely to be diagnosed with CRC in older age group (OR= 0.468, 95% CI 0.285, 0.796). Lower BMI was associated with a higher risk of mortality (p= 0.012). There was no difference in survival in younger and older populations. CONCLUSIONS: CRC is increasing in the younger population, and Hispanics are diagnosed with CRC usually at a younger age. Early screening in young populations with average risk and even earlier screening in high-risk populations like Hispanics is warranted for timely recognition for prevention, early management, and reduction of mortality.

Effectiveness of bevacizumab exposure beyond disease progression in patients with non-small-cell lung cancer: analyses of the ARIES observational cohort study.

PURPOSE: Bevacizumab used in combination with first-line chemotherapy confers an overall survival (OS) benefit for patients with non-squamous non-small-cell lung cancer (NSCLC). This analysis from the ARIES observational cohort study (OCS) was initiated to evaluate the effect of bevacizumab use beyond disease progression (BBP) on clinical outcomes in patients with NSCLC receiving first-line treatment with bevacizumab and chemotherapy. METHODS: The ARIES OCS prospectively enrolled patients from 2006 to 2009 in the United States who had advanced non-squamous NSCLC, received bevacizumab with chemotherapy in the first-line setting, and survived progressive disease (PD). A dichotomous landmark analysis examined post-PD OS (ppOS) in patients who received BBP versus no BBP within 30 days post PD. A time-dependent Cox model assessed the effect of cumulative BBP exposure on ppOS. RESULTS: The ARIES OCS enrolled 1967 patients with first-line NSCLC; 1358 patients had first PD and were alive at the 30-day landmark (351 patients with BBP and 1007 patients with no BBP). The landmark analysis showed that BBP was associated with a lower risk of death (BBP versus No-BBP); hazard ratio [HR], 0.75; 95% confidence interval 0.65-0.86. In the cumulative exposure analysis of 1461 patients who had PD, HRs for ppOS decreased by approximately 4% for each additional 21-day interval of bevacizumab received. Protocol-specified bevacizumab-select adverse events occurred in 14% of BBP patients. CONCLUSIONS: BBP was associated with a lower risk of death in patients with NSCLC treated with first-line bevacizumab and chemotherapy. Copyright © 2016 John Wiley & Sons, Ltd.

Effectiveness and safety of post-induction phase bevacizumab treatment for patients with non-small-cell lung cancer: results from the ARIES observational cohort study.

Data from randomized, controlled trials suggest that post-induction phase (IP) treatment with bevacizumab may benefit patients with advanced non-small-cell lung cancer (NSCLC). Real-world clinical practice, however, can involve variable use and patterns of treatment in broader patient populations. To assess the effect of bevacizumab on post-IP overall survival (OS) following IP chemotherapy + bevacizumab, analyses were conducted in patients enrolled in the Avastin(®) Registry--Investigation of Effectiveness and Safety (ARIES) observational cohort study (OCS) who received post-IP bevacizumab. ARIES was a large, prospective OCS of patients who received chemotherapy in combination with bevacizumab for the first-line treatment of NSCLC. This unplanned, post hoc analysis included patients who received chemotherapy and bevacizumab and who did not have progressive disease through the completion of IP treatment. A dichotomous analysis compared outcomes in patients who did and did not receive bevacizumab before a landmark date of day 30 post IP. A cumulative exposure analysis used a time-dependent Cox regression model to assess the effect of cumulative post-IP bevacizumab exposure on post-IP OS. In the dichotomous analysis, the duration of post-IP OS was significantly longer in patients who received post-IP bevacizumab; median post-IP OS was 15.6 vs. 11.3 months, respectively (hazard ratio [HR] = 0.80; 95 % confidence interval 0.71-0.91; P < 0.001). The cumulative exposure analysis observed that each additional cycle of cumulative bevacizumab exposure decreased the HR for post-IP OS by 2.7 %, on average. In conclusion, post-IP bevacizumab exposure was associated with improved post-IP OS in patients with advanced NSCLC who were enrolled in the ARIES OCS.

Safety and effectiveness of bevacizumab-containing treatment for non-small-cell lung cancer: final results of the ARIES observational cohort study.

INTRODUCTION: Bevacizumab, a recombinant humanized monoclonal antibody against vascular endothelial growth factor, was approved by the US Food and Drug Administration for the treatment of advanced non-small-cell lung cancer (NSCLC) in combination with carboplatin and paclitaxel. ARIES (Avastin Regimens: Investigation of Effectiveness and Safety), a prospective observational cohort study, evaluated outcomes in a large, community-based population of patients with first-line NSCLC. METHODS: From 2006 to 2009, ARIES enrolled patients with locally advanced or metastatic NSCLC who were eligible for bevacizumab, excluding those with predominantly squamous histology. Patients were required to provide informed consent and to have initiated bevacizumab with chemotherapy within 4 months before enrollment. There were no protocol-defined treatments or assessments. The dosing of bevacizumab and chemotherapy, and the choice of chemotherapy regimen, was at the discretion of the treating physician. RESULTS: ARIES enrolled 1967 patients with first-line NSCLC. At study closure, median follow-up was 12.5 months (range, 0.2-65.5). Median age was 65 years (range, 31-93), and 252 patients (12.8%) identified as never smokers. Median progression-free survival was 6.6 months (95% confidence interval, 6.3-6.9), and median overall survival was 13.0 months (95% confidence interval, 12.2-13.8) with first-line bevacizumab plus chemotherapy. Incidences of bevacizumab-associated adverse events (19.7% overall) were consistent with those in randomized controlled trials of bevacizumab in NSCLC. CONCLUSION: Results from ARIES demonstrate similar outcomes to randomized controlled trials of bevacizumab when added to standard chemotherapy in a real-world patient population with advanced NSCLC.

Bevacizumab exposure beyond first disease progression in patients with metastatic colorectal cancer: analyses of the ARIES observational cohort study.

PURPOSE: This analysis from Avastin® Registries: Investigation of Effectiveness and Safety (ARIES) examined the association between exposure to bevacizumab after disease progression (PD) and postprogression survival (PPS) in bevacizumab-exposed metastatic colorectal cancer (mCRC) through the application of time-dependent and time-fixed analytical methods. METHODS: Patients with mCRC who were treated with first-line bevacizumab and who survived first PD (PD1) were included. A time-dependent Cox regression model was fitted to assess the effect of cumulative bevacizumab exposure on PPS, while controlling for potential confounders. In addition to support findings from previous studies, a modified intent-to-treat (mITT) analysis compared PPS in patients who received bevacizumab beyond disease progression (BBP) with those who did not (No-BBP). RESULTS: Of 1550 patients, 1199 survived PD1 and had a median PPS of 13.4 months. Cumulative bevacizumab exposure was associated with improved PPS (p = 0.0040). After adjusting for confounders, the hazard ratios (HRs) for PPS decreased, on average, by 1.2% (range, 1.1-1.3%) with each additional dose of bevacizumab. In the mITT analysis, the median PPS for BBP (n = 438) was 14.4 months vs 10.6 months with for No-BBP (n = 667). BBP was found to be independently associated with longer PPS in a multivariable Cox regression analysis (HR, 0.84; 95% confidence interval, 0.73-0.97). Protocol-specified adverse events suspected to be associated with bevacizumab occurred in 13.0% of patients with BBP. CONCLUSION: This analysis supports the observation that bevacizumab exposure after PD1 is associated with longer PPS in mCRC.

Treatment patterns and clinical outcomes in patients with metastatic colorectal cancer initially treated with FOLFOX-bevacizumab or FOLFIRI-bevacizumab: results from ARIES, a bevacizumab observational cohort study.

BACKGROUND: The Avastin Registry: Investigation of Effectiveness and Safety (ARIES) study is a prospective, community-based observational cohort study that evaluated the effectiveness and safety of first-line treatment patterns, assessing the impact of chemotherapy choice and treatment duration. METHODS: The ARIES study enrolled patients with metastatic colorectal cancer (mCRC) receiving first-line chemotherapy with bevacizumab and followed them longitudinally. The protocol did not specify treatment regimens or assessments. Analyses included all patients who initiated bevacizumab in combination with either first-line oxaliplatin with infusional 5-fluorouracil and leucovorin (FOLFOX) or irinotecan with infusional 5-fluorouracil and leucovorin (FOLFIRI). Progression-free survival (PFS) and overall survival (OS) times were estimated using Kaplan-Meier methods. Hazard ratios (HRs) were estimated with multivariate Cox regression analysis, adjusting for potential confounding factors. RESULTS: In total, 1,550 patients with first-line mCRC were enrolled (median follow-up, 21 months) and most received FOLFOX-bevacizumab (n = 968) or FOLFIRI-bevacizumab (n = 243) as first-line therapy. The baseline characteristics and median treatment duration were generally similar between subgroups. There were no significant differences in the median PFS (10.3 months vs. 10.2 months) or OS (23.7 months vs. 25.5 months) time between the FOLFOX-bevacizumab and FOLFIRI-bevacizumab subgroups, respectively, by unadjusted analyses. Multivariate analyses showed FOLFIRI-bevacizumab resulted in a similar PFS (HR, 1.03; 95% confidence interval [CI], 0.88-1.21) and OS (HR, 0.95; 95% CI, 0.78-1.16) outcome as with FOLFOX-bevacizumab. The incidence proportions of bevacizumab-associated adverse events were similar for FOLFOX- and FOLFIRI-based therapies. CONCLUSIONS: In first-line mCRC patients, the FOLFOX-bevacizumab and FOLFIRI-bevacizumab regimens were associated with similar treatment patterns and clinical outcomes.

Discovery of potent and selective matrix metalloprotease 12 inhibitors for the potential treatment of chronic obstructive pulmonary disease (COPD).

Chronic obstructive pulmonary disease (COPD) is an inflammatory lung disease associated with irreversible progressive airflow limitation. Matrix metalloproteinase-12 (MMP-12) has been characterized to be one of the major proteolytic enzymes to induce airway remodeling, destruction of elastin and the aberrant remodeling of damaged alveoli in COPD and asthma. The goal of this project is to develop and identify an orally potent and selective small molecule inhibitor of MMP-12 for treatment of COPD and asthma. Syntheses and structure-activity relationship (SAR) studies of a series of dibenzofuran (DBF) sulfonamides as MMP-12 inhibitors are described. Potent inhibitors of MMP-12 with excellent selectivity against other MMPs were identified. Compound 26 (MMP118), which exhibits excellent oral efficacy in the MMP-12 induced ear-swelling inflammation and lung inflammation mouse models, had been successfully advanced into Development Track status.

Gob-5 contributes to goblet cell hyperplasia and modulates pulmonary tissue inflammation.

Gob-5 is a member of the calcium-activated chloride channel family and has been associated with allergic response in mouse models of pulmonary inflammation. Gene expression of Gob-5 has been shown to be induced in allergic airways and has been strongly associated with mucin gene regulation and goblet cell hyperplasia. We investigated the physiologic role of Gob-5 in murine models of pulmonary inflammation using mice deficient in Gob-5. After sensitization and aerosol challenge with ovalbumin (OVA), Gob-5 knockout mice exhibit significantly increased bronchoalveolar lavage (BAL) inflammation as compared with wild-type controls. The augmented inflammation in BAL consisted predominantly of neutrophils. Examination of perivascular inflammation revealed that tissue inflammation was decreased in OVA-challenged Gob-5-/- mice. OVA-challenged Gob-5 knockout mice also had decreased goblet cell hyperplasia as well as decreased mucus production. These mice also had decreased airway hypersensitivity after cholinergic provocation with methacholine. Gob-5 knockout mice were also challenged via intranasal LPS, a TLR-4 agonist. Gob-5-/- mice responded with increased neutrophilic BAL inflammation and decreased perivascular tissue inflammation as compared with wild-type controls. There was little effect on goblet cell hyperplasia and mucus production after LPS challenge. These observations reinforce findings that associate Gob-5 with goblet cell hyperplasia and mucus production in the allergic immune response, but also implicate Gob-5 in the regulation of tissue inflammation in the innate immune response.
