Introduction: Genomic variations among individuals can greatly affect their responses to different medications. Pharmacogenomics is the area of study that aims to understand the relationship between these various genetic variations and subsequent drug responses. Many medications used to optimize cardiovascular health are affected by these genetic variants and these relationships can subsequently impact dosing strategies in patients. Objective: This study aims to review the current literature on the clinical applications ofpharmacogenomics for commonly used cardiovascular medications such as Warfarin, Clopidogrel, Statins, Beta Blockers, and ACE-I/ARBs. Methods: Databases like PubMed were accessed to gather background information on pharmacogenomics and to collect data on relationships between genetic variants and subsequent drug response. Information on clinical applications and guidelines was obtained by accessing the CPIC and DPWG databases. Results: This article describes the most up-to-date data on pharmacogenomics relating to commonly used cardiovascular medications. It also discusses the clinical application of pharmacogenomic data as it pertains to medication selection/dosing by detailing current guidelines published by organizations such as the Clinical Pharmacogenetics Implementation Consortium and the Dutch Pharmacogenetics Working Group. Conclusion: In conclusion, this paper will help medical providers not only better understand pharmacogenomics but also apply it in their day-to-day practice. Clinical guidelines relating to the application of pharmacogenomic data were discussed both in text and graphical format, allowing providers to confidently select medications and adjust doses for common cardiovascular medications so that patients receive the maximum therapeutic benefit with minimal toxicity.
Trends in participant race and sex reporting in lung cancer phase III clinical trials
AbstractBackgroundClinical trials are an essential part of advancing care for cancer patients. Historically, however, racial minorities and females have been underrepresented in these trials. Efforts like the National Institute of Health Revitalization Act attempted to mitigate these disparities, but despite these efforts, they continue to exist. These disparities can subsequently lead to minorities and females receiving suboptimal care.AimsThe purpose of our study was to understand the changing trends in reporting of participant race and sex as a demographic variable in phase III lung cancer clinical trials published over the last 35 years given these consequences of poor representation.Methods and resultsA total of 426 articles reporting the results of phase III lung cancer clinical trials published from 1984 to 2019 were identified in PubMed. From these articles, data on participant sex and race were collected from the demographic tables to construct the database for this study. This database was subsequently used to determine the rate of reporting of demographic factors like race and sex and the participation trends over the time of minority and female participation in lung cancer phase III clinical trials. The SciPy Stats package for Python was used to calculate descriptive statistics, 95% confidence intervals, two sample t‐test, one‐way analysis of variance test, and Pearson's correlation coefficients. The Matplotlib package for Python was used for figure generation. Only 137 (32.2%) of the 426 studies analyzed reported the race of participants. Among those studies, we found that the mean participation rate of White participants was significantly higher (82.65%; p < .001). We found a decrease in African American participants and an increase in Asian participants over time. When looking at sex, we found that although the rate of male participation (69.02%) was significantly higher than that of female participation (30.98%), female participation has improved with time at a rate of 0.65% per year.ConclusionWe found that the reporting and participation of minority races continue to lag that of other demographic factors like sex in phase III clinical trials in lung cancer. Based on our analysis, we note a decline in participation of African Americans in lung cancer phase III clinical trials despite the rising incidence of lung cancer.
Trends in race and sex reporting in lung cancer phase III clinical trials
Background: To understand the changing trends in reporting of race and sex as a demographic variable in phase III lung cancer clinical trials published over the last 35 years. Methods: A total of 426 articles reporting results of phase 3 lung cancer clinical trials published from 1984 to 2019 were identified in PubMed. Statistical analysis on trends over time on percentage of minority and female participation were performed. Results: Only 137 (32.2%) of the 426 studies analyzed reported race of participants. Among those studies, we found that the mean participation rate of white participants was significantly higher (82.65%) (p < 0.001). We found a decrease in African American participants and an increase in Asian participants over time. When looking at sex, we found that although the rate of male participation (69.02%) was significantly higher than that of female participation (30.98%), the female participation has improved with time at a rate of 0.65% per year. Conclusions: We found that the reporting and participation of minority races continues to lag that of other demographic factors like sex in phase III clinical trials in lung cancer. Especially in African Americans, where the participation in lung cancer phase III clinical trials has declined despite the rising incidence in lung cancer.
Utility of AST to platelet ratio index (APRI) score in predicting post-surgical outcomes in patients with cholangiocarcinoma.
502 Background: Cholangiocarcinoma (CCA) is an epithelial malignancy of the intrahepatic or extrahepatic biliary tree, primarily driven by chronic inflammation and fibrosis. Given fibrosis has shown to correlate with malignancy and the aminotransferase-platelet ratio index (APRI) score, a marker for hepatic fibrosis, has shown to be useful in prognosticating hepatocellular carcinoma, this study aimed to assess the utility of APRI score in prognosticating post-surgical outcomes in CCA patients. Methods: 152 CCA patients at the Mayo Clinic that underwent surgical resection were retrospectively analyzed. Statistical analyses were then conducted to determine the relationship between APRI score and demographic factors, laboratory values (CA19-9, albumin, bilirubin, INR, alkaline Phosphatase, ALT, AST, and platelet count), pathology features, and outcome data. Results: When looking at demographic factors, no relationship between APRI score and age (r = -0.19, p = 0.02), sex (2-sample t-test p = 0.16) and race (ANOVA p = 0.81) were identified. There was a negative correlation between APRI score and albumin (m = -0.35, r = -0.35, p < 0.01) and a positive correlation with bilirubin (m = 0.13, r = 0.23, p = 0.01) and ALT (m = 0.01, r = 0.47, p < 0.01). No correlation between the other laboratory values analyzed was identified. Similarly, there was no relationship between APRI score and pathology features (tumor grade t-test p = 0.41, N Stage ANOVA p = 0.94, Vascular Invasion t-test p = 0.59, and Perineural invasion t-test p = 0.14), except for T3 stage which had a higher APRI score compared to T1, T2, and T4 (ANOVA p = 0.01). Likewise, APRI also did not correlate with post-surgical outcomes like recurrence (t-test p = 0.22) and mortality (t-test p = 0.39). Conclusions: In summary, despite being driven by chronic inflammation, APRI score, a marker for hepatic inflammation and a surrogate for liver fibrosis, did not serve as a reliable prognostication tool of post-surgical outcomes in CCA patients. These data suggest that although chronic inflammation is thought to be one of the primary drivers of disease, the role of other factors such as genetic and cellular signaling abnormalities may play a more prominent role in patients with CCA. In conclusion, APRI score did not serve as a useful prognostication tool in surgically resected CCA patients. Future studies should focus on other prognostic factors such as genomic and transcriptomic biomarkers in CCA.
Characterization of Morreton virus as an oncolytic virotherapy platform for liver cancers
Background: Morreton virus (MORV) is an oncolytic Vesiculovirus , genetically distinct from vesicular stomatitis virus (VSV). Aim: To report that MORV induced potent cytopathic effects (CPEs) in cholangiocarcinoma (CCA) and hepatocellular carcinoma (HCC) in vitro models. Approach and Results: In preliminary safety analyses, high intranasal doses (up to 10 10 50% tissue culture infectious dose [TCID 50 ]) of MORV were not associated with significant adverse effects in immune competent, non–tumor‐bearing mice. MORV was shown to be efficacious in a Hep3B hepatocellular cancer xenograft model but not in a CCA xenograft HuCCT1 model. In an immune competent, syngeneic murine CCA model, single intratumoral treatments with MORV (1 × 10 7 TCID 50 ) triggered a robust antitumor immune response leading to substantial tumor regression and disease control at a dose 10‐fold lower than VSV (1 × 10 8 TCID 50 ). MORV led to increased CD8 + cytotoxic T cells without compensatory increases in tumor‐associated macrophages and granulocytic or monocytic myeloid‐derived suppressor cells. Conclusions: Our findings indicate that wild‐type MORV is safe and can induce potent tumor regression via immune‐mediated and immune‐independent mechanisms in HCC and CCA animal models without dose limiting adverse events. These data warrant further development and clinical translation of MORV as an oncolytic virotherapy platform.
