Global Safety Assessment of Adverse Events of Special Interest Following 2 Years of Use and 772 Million Administered Doses of mRNA-1273.

Background: Large-scale use of mRNA COVID-19 vaccines during the pandemic was associated with enhanced safety monitoring to ensure accurate and timely review of safety. We reviewed the mRNA-1273 (original strain) safety profile following 2 years of use (>772 million administered doses), primarily focusing on predefined safety topics (ie, adverse events of special interest [AESIs]) proposed in advance of COVID-19 vaccine use.

Methods: Cumulative mRNA-1273 safety data were included from spontaneous adverse event (AE) cases reported to Moderna's global safety database between 18 December 2020 and 17 December 2022.

A Brighton Collaboration standardized template with key considerations for a benefit/risk assessment for the Moderna COVID-19 Vaccine (mRNA-1273).

The Brighton Collaboration Benefit-Risk Assessment of VAccines by TechnolOgy (BRAVATO) Working Group has prepared standardized templates to describe the key considerations for the benefit-risk assessment of several vaccine platform technologies, including nucleic acid (RNA and DNA) vaccines. This paper uses the BRAVATO template to review the features of a vaccine employing a proprietary mRNA vaccine platform to develop Moderna COVID-19 Vaccine (mRNA-1273); a highly effective vaccine to prevent coronavirus disease 2019 (Covid-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In response to the pandemic the first in human studies began in March 2020 and the pivotal, placebo-controlled phase 3 efficacy study in over 30,000 adults began in July 2020.

Analysis of Myocarditis Among 252 Million mRNA-1273 Recipients Worldwide.

Background: Growing evidence indicates a causal relationship between SARS-CoV-2 infection and myocarditis. Post-authorization safety data have also identified myocarditis as a rare safety event following mRNA COVID-19 vaccination, particularly among adolescent and young-adult males after dose 2. We further evaluated the potential risk by querying the Moderna global safety database for myocarditis/myopericarditis reports among mRNA-1273 recipients worldwide.

Hepatic safety of the antifungal triazole agent posaconazole: characterization of adverse event reports in a manufacturer's safety database.

Background: Second generation triazoles including posaconazole are efficacious for prophylaxis and salvage treatment of life-threatening invasive fungal diseases but have been associated with hepatic adverse events (AEs). This report evaluated hepatic AEs in posaconazole-treated patients.

Research Design And Methods: Hepatobiliary AEs occurring after posaconazole exposure in the company's global safety database were analyzed to characterize underlying medical conditions and concomitant drug exposure.

Integrative Analysis of Randomized Clinical Trial and Observational Study Data to Inform Post-marketing Safety Decision-Making.

Safety evaluation is a continual and iterative process throughout the drug development life cycle and requires long time horizons and large amounts of data to fully understand the safety profile of a medical product. Although randomized clinical trials (RCT) provide high-quality data for an initial assessment of safety signals, the safety signals may not all have been known at the time of approval because safety data collected from RCT only involve a relatively small number of subjects during a relatively short follow-up period. The increased accumulation of post-marketing real-world data (RWD) presents an opportunity to utilize them for safety decision-making; these include identifying new safety signals, further characterization of safety concerns that are raised in pre-marketing RCT, and further generalization of RCT findings to the broader patient populations not previously studied in RCT.

A Health Literate Patient-focused Approach to the Redesign of the Raltegravir (ISENTRESS) Pediatric Kit and Instructions for Use.

Background: Limited data exist regarding how medications for pediatric use can be developed to minimize medication errors. The integrase inhibitor raltegravir was developed for use in neonates (≥2 kg). Anticipating that neonatal administration would be performed primarily by mothers with varying degrees of health literacy, a health literate, patient-focused, iterative process was conducted to update/redesign the raltegravir granules for oral suspension pediatric kit and instructions for use (IFU) for neonatal use to be ready for regulatory submission.

Varicella Virus Vaccine Live: A 22-Year Review of Postmarketing Safety Data.

Background: Varicella, a contagious infectious disease caused by varicella zoster virus (VZV), can result in hospitalization and, occasionally, death. Varicella virus vaccine live (VVVL [VARIVAX]) was introduced in the United States in 1995.

Methods: This comprehensive review of the VVVL safety profile is based on 22 years of postmarketing adverse event (AE) data received through spontaneous and noninterventional study reports submitted by health care providers and on a review of the published literature (cumulatively from March 17, 1995, through March 16, 2017, during which period >212 million doses were distributed globally).

Evaluation of Neural Tube Defects (NTDs) After Exposure to Raltegravir During Pregnancy.

Objective: To evaluate the risk of neural tube defects (NTDs) after exposure to raltegravir during pregnancy.

Methods: Exposures to raltegravir during pregnancy reported cumulatively through May 31, 2018, to the company safety database were reviewed to identify cases of NTDs. This database includes all reports of pregnancy from Merck-sponsored clinical trials, spontaneous postmarketing reports, and non-interventional data sources, including the Antiretroviral Pregnancy Registry (APR).

Turning up the heat: Effect of new vaccine for children's (VFC) program recommendations for use of temperature monitors upon incorrect product storage adverse event reporting.

Background: The Centers for Disease Control and Prevention (CDC) coordinates the Vaccines For Children (VFC) program, which provides free vaccines to qualified children in the US. In 2009, the CDC issued Vaccine Storage Requirements, which were later replaced (2012) with an interim guidance and toolkit for vaccine storage and handling. The guidance called for use of Digital Data Loggers (DDL) to monitor vaccine storage temperatures.

Osteoarthritis patients with pain improvement are highly likely to also have improved quality of life and functioning. A post hoc analysis of a clinical trial.

Background: This analysis evaluated whether osteoarthritis patients achieving the greatest pain control and lowest pain states also have the greatest improvement in functioning and quality of life.

Methods: Patients (n=419) who failed prior therapies and who were switched to etoricoxib 60mg were categorized as pain responders or non-responders at 4 weeks based on responder definitions established by the Initiative on Methods, Measurement, and Pain (IMMPACT) criteria, including changes from baseline of ≥15%, ≥30%, ≥50%, ≥70% and a final pain status of ≤3/10 (no worse than mild pain). Pain was assessed at baseline and 4 weeks using 4 questions from the Brief Pain Inventory (BPI) (worst pain, least pain, average pain, and pain right now), and also using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain subscale.

Burden of childhood rotavirus disease on health systems in the United States.

Background: To determine the burden of rotavirus disease before the introduction of rotavirus vaccines.

Methods: From February 2005 to June 2006, prospective rotavirus surveillance was conducted in Cincinnati, Ohio, and Durham, North Carolina. Children < 5 years of age presenting at hospitals and outpatient clinics with acute gastroenteritis (AGE) of < 72 hours duration were enrolled.

International epidemiology of human pre-existing adenovirus (Ad) type-5, type-6, type-26 and type-36 neutralizing antibodies: correlates of high Ad5 titers and implications for potential HIV vaccine trials.

Replication-defective adenoviruses have been utilized as candidate HIV vaccine vectors. Few studies have described the international epidemiology of pre-existing immunity to adenoviruses. We enrolled 1904 participants in a cross-sectional serological survey at seven sites in Africa, Brazil, and Thailand to assess neutralizing antibodies (NA) for adenovirus types Ad5, Ad6, Ad26 and Ad36.

Effectiveness of a bivalent Haemophilus influenzae type B-hepatitis B vaccine in preventing hepatitis B virus infection among children born to hepatitis B e antigen-positive carrier mothers.

Background: This observational study evaluated a modified immunoprophylactic regimen (hepatitis B immune globulin [HBIG]) and a dose of thimerosal-free monovalent hepatitis B (HB) vaccine shortly after birth followed by doses of thimerosal-free bivalent Haemophilus influenzae type b (Hib)-HB vaccine at 2 and 4 months of age, and a booster at 12 months of age) in infants at high risk of hepatitis B virus (HBV) infection (mothers HBeAg+).

Methods: Children >or=6 months of age vaccinated in routine clinical practice were tested twice (>or=6 months apart) for HBV antigens surface antigen (HBsAg) and "e" antigen, and for antibody to HBsAg. Partial nucleotide sequence analysis was performed on HBV DNA isolated from infants identified with a breakthrough chronic HBV infection.

Incidence of and preoperative risk factors for Staphylococcus aureus bacteremia and chest wound infection after cardiac surgery.

Objective: Staphylococcus aureus infections after cardiac surgery result in significant morbidity and mortality. Identifying patients at elevated risk for these infections preoperatively could facilitate efforts to reduce infection rates. The objectives of this study were to estimate the incidence of postoperative S.

Comparison of methods to detect recent HIV type 1 infection in cross-sectionally collected specimens from a cohort of female sex workers in the Dominican Republic.

Interest in estimating HIV-1 incidence using specimens obtained as part of cross-sectional surveys has led to the development of new methods to detect recent HIV-1 infection through the testing of a single anti-HIV-positive specimen. These assays are based on quantitative and qualitative differences in anti-HIV-1 antibodies between recent and long-standing infections. An ongoing vaccine preparedness study enrolled female sex workers in the Dominican Republic.

Detection of HIV vaccine-induced cell-mediated immunity in HIV-seronegative clinical trial participants using an optimized and validated enzyme-linked immunospot assay.

An effective vaccine for HIV is likely to require induction of T-cell-mediated immune responses, and the interferon-gamma (IFNgamma) enzyme-linked immunospot (ELISPOT) assay has become the most commonly used assay for measuring these responses in vaccine trials. We optimized and validated the HIV ELISPOT assay using an empirical method to establish positivity criteria that results in a < or =1% false-positive rate. Using this assay, we detected a broad range of HIV-specific ELISPOT responses to peptide pools of overlapping 20mers, 15mers, or 9mers in study volunteers receiving DNA- or adenovirus vector-based HIV vaccines and in HIV-seropositive donors.

Estimating the benefit of an HIV-1 vaccine that reduces viral load set point.

Vaccines designed to induce cell-mediated immune responses against human immunodeficiency virus (HIV)-1 are being developed. Such vaccines are unlikely to provide sterilizing immunity but may be associated with reduced viral set points after infection. We modeled the potential impact of a vaccine that reduces viral set point after infection, using natural history data from 311 HIV-1 seroconverters.

An evaluation of a patient-reported outcomes found computerized adaptive testing was efficient in assessing osteoarthritis impact.

Background And Objectives: Evaluate a patient-reported outcomes questionnaire that uses computerized adaptive testing (CAT) to measure the impact of osteoarthritis (OA) on functioning and well-being.

Materials And Methods: OA patients completed 37 questions about the impact of OA on physical, social and role functioning, emotional well-being, and vitality. Questionnaire responses were calibrated and scored using item response theory, and two scores were estimated: a Total-OA score based on patients' responses to all 37 questions, and a simulated CAT-OA score where the computer selected and scored the five most informative questions for each patient.

Cross-clade reactivity of HIV-1-specific T-cell responses in HIV-1-infected individuals from Botswana and Cameroon.

An effective HIV type 1 (HIV-1) vaccine will likely require elicitation of broadly reactive cell-mediated immune (CMI) responses against divergent HIV-1 clades. We compared anti-HIV-1 T-cell immune responses among 363 unvaccinated adults infected with diverse HIV-1 clades. Response rates to clade B Gag and/or clade B Nef in Botswana (95%) and Cameroon (98%) were similar when compared with those in countries previously studied, including Brazil (92%), Thailand (96%), South Africa (96%), Malawi (100%), and the United States (100%).

Colorectal cancer screening attitudes and practices in the general population: a risk-adjusted survey.

Objectives: To characterize self-reported colorectal cancer (CRC) screening behavior, and to identify characteristics of CRC screening practices, stratified by risk.

Methods: Using random-digit-dial methodology, we conducted telephone surveys in US adults 50 years of age and older. Respondents provided data on utilization of CRC screening tests; demographic characteristics; and awareness, concerns, attitudes and beliefs about the tests, CRC, and health care.

Cross-reactivity of anti-HIV-1 T cell immune responses among the major HIV-1 clades in HIV-1-positive individuals from 4 continents.

Background: The genetic diversity of human immunodeficiency virus type 1 (HIV-1) raises the question of whether vaccines that include a component to elicit antiviral T cell immunity based on a single viral genetic clade could provide cellular immune protection against divergent HIV-1 clades. Therefore, we quantified the cross-clade reactivity, among unvaccinated individuals, of anti-HIV-1 T cell responses to the infecting HIV-1 clade relative to other major circulating clades.

Methods: Cellular immune responses to HIV-1 clades A, B, and C were compared by standardized interferon- gamma enzyme-linked immunospot assays among 250 unvaccinated individuals, infected with diverse HIV-1 clades, from Brazil, Malawi, South Africa, Thailand, and the United States.

A comparison of the efficacy and safety of nonsteroidal antiinflammatory agents versus acetaminophen in the treatment of osteoarthritis: a meta-analysis.

Objective: To perform a meta-analysis comparing the efficacy and safety of recommended dosages of nonsteroidal antiinflammatory drugs (NSAIDs), including cyclooxygenase 2 inhibitors, versus acetaminophen in the treatment of symptomatic hip and knee osteoarthritis.

Methods: Medline and EMBASE searches were performed for original clinical trials directly comparing NSAIDs with acetaminophen. A standardized form was used to abstract all data, including outcome measures of pain at rest, walking pain, and dropouts due to adverse effects.
