RESUMO

Pharmacovigilance plays a lifesaving role in the practice of medicine. In 2021, during the Coronavirus Infectious Disease 2019 (COVID-19) pandemic, Loyola University Chicago launched a graduate-level Pharmacovigilance Certificate Program (PV-CERT) and a pre-professional non-graduate Pharmacovigilance Certificate Course (EPEC-PV), to provide students a comprehensive and contemporary understanding of the principles and practices of pharmacovigilance. Formal training in pharmacovigilance through this course provided a structured understanding of how safety data are generated through clinical trials and from real-world evidence as well as the regulatory environment in which data are monitored and interpreted. Pharmacovigilance training is of critical importance, especially during the COVID-19 pandemic, during which several drugs were re-purposed for the management of various stages of COVID-19 without conventional safety data. Moreover, the safety of currently-used vaccines is of concern in some populations. Although anticoagulants and antithrombotic medications are crucial in the management of COVID-19, a clear pharmacovigilance program on their use in this indication is not established. As the century progresses, new diseases and infectious agents will require novel therapies for which the evaluation of benefits versus risks will be as essential as it has been for the current COVID-19 pandemic. As such, the Loyola course and accompanying programs on pharmacovigilance will play a key role in educating the next generation of professionals in pursuing careers in the development of therapies that ultimately improve patient outcomes while maintaining rigorous safety standards.

RESUMO

The progress in the development of various vaccine platforms against SARS-CoV-2 have been rather remarkable owing to advancement in molecular and biologic sciences. Most of the current vaccines and those in development focus on targeting the viral spike proteins by generating antibodies of varying spectrum. These vaccines represent a variety of platforms including whole virus vaccines, viral vector vaccines, nucleic acid vaccines representing RNA, DNA, and their hybrid forms.The therapeutic efficacy of these vaccines varies owing to their pharmacodynamic individualities. COVID-19 variants are capable of inducing different pathologic responses and some of which may be resistant to antibodies generated by current vaccines. The current clinical use of these vaccines has been through emergency use authorization until recently. Moreover, the efficacy and safety of these vaccines have been tested in substantial numbers of individuals but studies in special populations that better reflect the global population are pending results. These specialized populations include young children, immunocompromised patients, pregnant individuals, and other specialized groups. Combination approaches, molecularly modified vaccination approaches, and vaccines conferring longer periods of immunity are being currently being investigated, as well as pharmacovigilance studies.The continual transformation of SARS-CoV-2 and its variants are of concern along with the breakthrough infections. These considerations pose new challenges for the development of vaccination platforms. For this purpose, booster doses, combination vaccine approaches, and other modalities are being discussed. This review provides an updated account of currently available vaccines and those in advanced development with reference to their composition and mechanisms of action.A discussion on the use of vaccines in special populations including immunocompromised patients, pregnant women and other specialized populations are also included.

RESUMO

BACKGROUND: Additional risk minimization measures (aRMMs) are required for some pharmaceutical products when routine risk minimization measures (i.e., product labeling) are deemed insufficient. Measures often include educational materials, such as paper brochures, leaflets, and/or alert cards that provide information to healthcare professionals and patients on the key risks associated with a product and risk minimization actions to take should particular signs or symptoms arise. Paper-based educational aRMMs have several limitations. They do not present information in an interactive manner, and their update and distribution can be costly and often complex. Measuring how effective they are in achieving their aims can also be difficult. Digital methods offer design and delivery flexibility, easier updating processes, opportunities to increase engagement with important information, as well possibilities for tracking distribution, receipt, and potentially understanding of the materials. Pharmaceutical companies have started to look to digital methods as an option for educational aRMMs, alongside paper materials. OBJECTIVES: Research into healthcare professionals and patient needs and preferences, as well as the general acceptability of digital educational options is needed to establish a baseline. This was an exploratory study intended to provide initial insights on the acceptability of digital aRMMs and to inform future research directions. METHODS: Digital concepts for educational aRMMs, one for healthcare professionals and one for patients, were evaluated with 30 healthcare professionals and 20 patients in six countries through 1:1 Zoom calls, with responses recorded in a structured Qualtrics-based survey. Criteria for selecting the six countries included local familiarity with aRMMs as well as interest in and capability to deliver a potential digital aRMM program by the sponsoring company's affiliate teams. Of the healthcare professionals, 19 were rheumatologists and 11 were dermatologists. 16 patients had rheumatologic (rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis) conditions and four had atopic dermatitis. These conditions were chosen as they aligned to potential therapeutic areas where the sponsoring company may have the opportunity to use a digital aRMM. Participants were given an overview of the concept as well as the opportunity to interact with it directly via the "control screen" function in Zoom before questions were posed. RESULTS: The results demonstrated that the majority of healthcare professionals (87%) and all patients interviewed would prefer website-based or app-based delivery, respectively, of aRMM information instead of, or alongside traditional paper-based approaches, with only 13% of healthcare professionals and no patients expressing a preference for paper-only communication. CONCLUSIONS: Given new options offered by digital technology, its widespread use in many fields, and the importance of patient safety as a topic, there is an imperative for pharmaceutical companies and regulators to work together to establish a way forward for the use of digital options for aRMMs. This study is limited in its generalizability but offers some ideas for future research directions.

RESUMO

Today the coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has become a global health problem. After more than a year with the pandemic, although our knowledge has progressed on COVID-19, there are still many unknowns in virological, pathophysiological and immunological aspects. It is obvious that the most efficient solution to end this pandemic are safe and efficient vaccines. This manuscript summarizes the pathophysiological and thrombotic features of COVID-19 and the safety and efficacy of currently approved COVID-19 vaccines with an aim to clarify the recent concerns of thromboembolic events after COVID-19 vaccination. The influx of newer information is rapid, requiring periodic updates and objective assessment of the data on the pathogenesis of COVID-19 variants and the safety and efficacy of currently available vaccines.

RESUMO

Antibody-drug conjugates (ADCs) are new treatment options for certain cancers, especially those in advanced states with limited treatment options. Their unique design provides targeted therapy with toxins that otherwise would not be available, but they manifest toxicities that require risk minimization interventions to optimize their tolerability. We summarize selected toxicities for ADCs that have been approved through the end of 2020 and three investigational ADCs, which include both payload and linker, as described in the US Prescribing Information, the European Summary of Product Characteristics, and study protocols. These toxicities include peripheral neuropathy; pulmonary, skin, hepatic, and ocular toxicities; hyperglycemia; left ventricular dysfunction; and fluid-related events. We also review the risk minimization approaches to managing these toxicities as described in the product labels and study protocols. Our general observation suggests that the selected toxicities of the approved ADCs are primarily associated with off-target effects of the drug payloads. We also observed that the risk minimization approaches used to manage the selected toxicities are similar across product labels and study protocols. ADCs provide a unique treatment approach that is currently focused on advanced or refractory cancers. The risk minimization approaches for the selected toxicities for the approved ADCs per product label, or the study protocol for those in clinical investigation, are similar to those of standard chemotherapy agents and other pharmaceutical agents for the treatment of advanced malignancies. These risk minimization measures align with standard medical practice and are likely familiar to and feasible for physicians who prescribe for, and to other healthcare practitioners who care for, patients treated with ADCs.

RESUMO

Recent guidance on safety monitoring during drug development, issued by regulatory authorities in the United States and European Union, indicate a shift in focus towards aggregate safety monitoring and scientific evaluation of integrated safety data. The call for program-level reviews of accumulating safety data, including from ongoing studies, provides an opportunity to leverage the scientific expertise and medical judgment of safety management teams with (a) a multidisciplinary approach, (b) quantitative frameworks to measure level of evidence, and (c) assessments that are product-specific and driven by medical judgment. A multidisciplinary team, regularly reviewing aggregate safety data throughout the development program, is vital not only for early signal detection but also for generating a better understanding of the accumulating data and context needed for decreasing false alarms.

RESUMO

BACKGROUND: Safety surveillance relies on mining of large pharmacovigilance (PV) databases to generate insights regarding the safe use of pharmaceutical products. The predominant approach to PV data mining involves computation of disproportionality scores for drug-adverse event (drug-AE) pairs. However, this approach requires a database to be sufficiently large, sufficiently diverse for the analysis to be reliably sensitive and specific, and fails to consider the particular safety profile of a product. OBJECTIVE: The present study proposes and tests a novel, frequency-based approach to PV data mining that (1) leverages product knowledge and historical drug-AE trends and (2) imposes no requirement for the size and diversity of the database to which it is applied. METHOD: A focus group of physicians and scientists was convened to identify quantitative characteristics of data trends that they consider informative when reviewing counts of adverse events for products under surveillance. Feedback was transferred into a series of decision rules that, when applied to adverse event counts, identifies adverse event trends that are classified as Continuing Trend, Emerging Trend, or No Trend. Regression analyses are completed to verify the presence of a linear trend; and categorical measures of association completed to compare this frequency-based approach to disproportionality scores in a simulated database. RESULTS: A significant, positive linear trend is present for the Continuing Trend and Emerging Trend categories ( P < .0001). There is a significant association between trend categorizations and disproportionality scores ( P < .0001). CONCLUSION: The proposed alternative frequency-based method for PV data mining would be useful where disproportionalities scores are not appropriate. Additionally, this method may be useful in conjunction with disproportionality scores, where appropriate, highlighting adverse events that are both reported disproportionately and have increasing trends.

RESUMO

OBJECTIVE: To present evidence supporting best-practices for prescription drug labeling and educational materials. METHODS: Articles were selected from three online databases (PubMed, Embase, CINAHL). Eligible manuscripts were: 1) English-language, 2) randomized, controlled trials, and 3) focused on improving prescription drug labeling practices. RESULTS: Forty-nine articles were reviewed, and included both regulated label materials and pharmacy or health systems-generated tools. Best-practices included use of plain language principles, typographic cues, quantitative descriptors, and standardized formats, when applicable. Common outcomes included preference and comprehension, while few studies examined actual medication use (e.g. adherence, harms) or clinical health outcomes. Approximately half of studies directly engaged patients' perspectives in intervention development, which may have helped increase tool effectiveness. CONCLUSIONS: Several best practices were apparent in the literature, particularly for written materials and pharmacy-generated container labeling. Design principles for supplemental instructions and multimedia tools were less cohesive, albeit less researched. The impact of patient involvement in tool design is promising, though requiring further study. PRACTICE IMPLICATIONS: Definitive studies to inform practice standards on how to best communicate medication information to consumers are needed, especially as communication modalities continue to evolve. Increased research on if and how to incorporate patient-centered decision-making into the development process should be considered.

RESUMO

The future of safety science is happening now and has the potential to improve patient outcomes through an evolving approach to benefit-risk assessment. Three building blocks for the future of safety science, cognitive and behavioral systems, medical assessment, and data science, individually and collaboratively advance and modernize the benefit-risk paradigm. Incorporating the patient perspective and patient experiences will help identify tools that are useful in real-world practice. Medical assessment teams will bring together the study of toxicity and toxicogenomics, biomarkers, and special populations to personalize the benefit-risk profile. Personalized benefit-risk profiles for patients will help improve outcomes. Data science and related quantitative sciences such as safety statistics, database integration, technology, and epidemiology will provide new approaches and tools for analysis of safety data as well as more rapid access to insights that benefit patients.

RESUMO

BACKGROUND: A quadrivalent human papillomavirus (HPV4) type 6/11/16/18 vaccine (GARDASIL/SILGARD®) has been licensed in many countries around the world for the prevention of cervical, vulvar, vaginal, and anal cancers and precancers, as well as external genital warts causally related to HPV types 6/11/16/18. Across 7 phase 3 clinical trials involving more than 29,000 males and females ages 9-45 years, vaccination was generally well tolerated. Because of its expected public health benefit in reducing cervical cancer and other HPV-related diseases, the vaccine has been implemented in the national vaccination programs of several countries, with over 178 million doses distributed worldwide. METHODS: Extensive efforts to assess the safety of the vaccine in routine practice have been conducted over the past 9 years since licensure, including more than 15 studies in more than 1 million preadolescents, adolescents and adults from various countries. Most have been performed in the general population although there have been some in special populations (pregnant women, HIV-infected individuals and those with systemic lupus erythematosus). RESULTS: We present a summary of the published, postlicensure safety data from active and passive surveillance. Only syncope, and possibly skin infections were associated with vaccination in the postlicensure setting. Serious adverse events, such as adverse pregnancy outcomes, autoimmune diseases (including Guillain-Barre Syndrome and multiple sclerosis), anaphylaxis, venous thromboembolism and stroke, were extensively studied, and no increase in the incidence of these events was found compared with background rates. CONCLUSIONS: These results, along with the safety data from the prelicensure clinical trials, confirm that the HPV4 vaccine has a favorable safety profile. Key policy, medical and regulatory organizations around the world have independently reviewed these data and continue to recommend routine HPV vaccination.

RESUMO

OBJECTIVE: To better describe the safety profile of pregnancy exposures to the qHPV vaccine by acquiring and analyzing post-marketing data on pregnancy outcomes. METHODS: This is a voluntary, post-marketing prenatal vaccine exposure registry. Enrollment criteria included an identifiable patient and health care provider from the United States, France, or Canada and exposure within 1 month before the date of onset of the last menstrual period or at any time during pregnancy. Outcomes of interest were pregnancy outcomes and birth defects. Prospectively reported cases were used for rate calculations. RESULTS: For the 1752 prospective reports with known outcome, 1518 (86.6%) were live births, including ten twin pregnancies. Of 1527 neonates, 1444 (94.6%) had no congenital anomalies. The overall rate of spontaneous abortion was 6.7 per 100 outcomes (95% confidence interval [CI] 5.5-8.2). The prevalence of major birth defects was 2.4 per 100 live-born neonates (95% CI 1.7-3.3). There were 12 fetal deaths (0.8 per 100 outcomes, 95% CI 0.4-1.4). CONCLUSION: Rates of spontaneous abortions and major birth defects were not greater than the general population rates. Although no adverse signals have been identified to date, the qHPV vaccine is not recommended for use in pregnant women.

RESUMO

M-M-R™II (measles, mumps, and rubella virus vaccine live; Merck, Sharp, & Dohme Corp.) is indicated for simultaneous vaccination against measles, mumps, and rubella in individuals ≥ 12 months of age. Before the vaccine era, these viruses infected most exposed individuals, with subsequent morbidity and mortality. One of the greatest achievements of public health has been to eliminate these 3 diseases in large geographic areas. The safety profile of M-M-R™II is described using data from routine global postmarketing surveillance. Postmarketing surveillance has limitations (including incomplete reporting of case data), but allows collection of real-world information on large numbers of individuals, who may have concurrent medical problems excluding them from clinical trials. It can also identify rare adverse experiences (AEs). Over its 32-year history, ≈ 575 million doses of M-M-R™II have been distributed worldwide, with 17,536 AEs voluntarily reported for an overall rate of 30.5 AEs/1,000,000 doses distributed. This review provides evidence that the vaccine is safe and well-tolerated.

RESUMO

BACKGROUND: Few population-based studies of infectious etiologies of fever-rash illnesses have been conducted. This study reports on enhanced febrile-rash illness surveillance in Campinas, Brazil, a setting of low measles and rubella virus transmission. METHODS: Cases of febrile-rash illnesses in individuals aged <40 years that occurred during the period 1 May 2003-30 May 2004 were reported. Blood samples were collected for laboratory diagnostic confirmation, which included testing for adenovirus, dengue virus, Epstein-Barr virus (EBV), enterovirus, human herpes virus 6 (HHV6), measles virus, parvovirus-B19, Rickettsia rickettsii, rubella virus, and group A streptococci (GAS) infections. Notification rates were compared with the prestudy period. RESULTS: A total of 1248 cases were notified, of which 519 (42%) had laboratory diagnosis. Of these, HHV-6 (312 cases), EBV (66 cases), parvovirus (30 cases), rubella virus (30 cases), and GAS (30 cases) were the most frequent causes of infection. Only 10 rubella cases met the rubella clinical case definition currently in use. Notification rates were higher during the study than in the prestudy period (181 vs 52.3 cases per 100,000 population aged <40 years). CONCLUSIONS: Stimulating a passive surveillance system enhanced its sensitivity and resulted in additional rubella cases detected. In settings with rubella elimination goals, rubella testing may be considered for all cases of febrile-rash illness, regardless of suspected clinical diagnosis.

RESUMO

BACKGROUND: Raltegravir has demonstrated potent and durable efficacy and a favorable safety profile in 3 phase III studies in treatment-naïve and treatment-experienced patients with HIV-1 infection. This manuscript provides a review of the raltegravir safety profile using data from these and other studies in the clinical development program. METHODS: Comprehensive 96-week safety data from STARTMRK (raltegravir versus efavirenz, each with tenofovir/emtricitabine) and BENCHMRK (raltegravir versus placebo, each with optimized background therapy) are summarized. A cumulative meta-analysis of raltegravir 400 mg bid was conducted across the entire development program. RESULTS: In STARTMRK, drug-related adverse events (AEs) occurred less frequently with raltegravir than efavirenz. In BENCHMRK, the most common drug-related AEs occurred at generally similar frequencies in both groups. Drug-related serious AEs were uncommon. Rash was observed in raltegravir-treated patients at a higher frequency than placebo but a lower frequency than efavirenz. Depression and immune reconstitution inflammatory syndrome occurred at similar rates for raltegravir and comparators. Isolated elevations of creatine kinase were more common with raltegravir than placebo but occurred without clinical manifestations. The frequency of aminotransferase elevations was greater in patients with viral hepatitis co-infection, but similar in the raltegravir and comparator groups. The relative risk (95% CI) of cancer was 0.75 (0.30, 1.91) indicating no difference between raltegravir and comparator. Overall trends in the cumulative meta-analysis were similar to those observed in the phase III studies. CONCLUSIONS: Long-term data from the phase III clinical trials demonstrate that raltegravir was generally well-tolerated in both treatment-naïve and treatment-experienced patients with HIV infection.

RESUMO

This paper assesses the cost-effectiveness of, and the return on the investment in, the 2002 catch-up and the 2003 follow-up measles campaigns in Afghanistan from the perspective of the donor. The catch-up campaign targeted nearly 12 million children aged between six months and 12 years, while the follow-up campaign targeted over five million children aged between 9 and 59 months. Both campaigns successfully vaccinated approximately 96 per cent of the respective target populations, and are expected to avert an estimated 301,000 measles deaths over the next 10 years. The average cost per dose of measles vaccine delivered was USD 0.40. The cost per death prevented is USD 23.6, assuming a case fatality rate of 10 per cent and a discount rate of three per cent. With more than 42,000 measles deaths avoided for every one million US dollars spent, the campaigns are an excellent public health investment for precluding childhood mortality in a country affected by a complex emergency.

RESUMO

Of the 540 measles cases (annual incidence, less than 1/million population) reported during 1997-2001 in the United States, 362 (67%) were associated with international importation: 196 imported cases, 138 cases epidemiologically linked to imported cases, and 28 cases associated with an imported measles virus genotype. The remaining 178 (33%) "unknown-source" cases were analyzed as potential evidence of endemic measles transmission. A total of 83 counties (2.6% of the 3140 US counties) in 27 states reported unknown-source cases; 49 counties reported only 1 unknown-source case, and the maximum reported by any county was 10. Nationally, unknown-source cases were reported in 103 of the 260 weeks. The largest unknown-source outbreak included 13 cases and lasted 5 weeks. The rarity of unknown-source cases, wide gaps in geographic and temporal distribution, and the short duration of the longest unknown-source outbreak indicate that endemic transmission of measles was not sustained in the United States during this period.

RESUMO

Serological evidence of measles virus infection has been detected among people exposed to measles who do not exhibit classical clinical symptoms. Throat swabs, lymphocytes, and serum and urine samples were collected from contacts of individuals with confirmed measles 12-16 days after exposure, during measles outbreaks occurring in 1998. Follow-up serum samples were drawn 2 weeks later. Samples were tested for measles IgM antibody by enzyme immunoassays and plaque reduction neutralization testing. Virus isolation and reverse transcriptase-polymerase chain reaction testing was attempted for all samples. None of the 133 contacts developed classical measles disease; 11 (8%) had serological evidence of infection. Duration of exposure of >or=3 h was the only significant risk factor for developing serological response (24% vs. 4% among contacts exposed for 1-2 h; relative risk, 6.0; 95% confidence interval, 1.9-19.2). None of the 133 contacts had virological evidence of infection by culture or polymerase chain reaction. We found no evidence that persons with inapparent measles virus infections shed measles virus.

RESUMO

In 2000, Costa Rica set a goal for accelerated rubella control and congenital rubella syndrome (CRS) prevention in conjunction with its established measles eradication goal. To achieve this goal, a National Plan of Action for the integration of a measles-rubella (MR) vaccination strategy was implemented. The components of the national plan included conducting a national vaccination campaign with a single dose of MR vaccine for men and women aged 15-39 years, establishing routine postpartum MR vaccination of all previously unvaccinated women, maintaining high coverage among children with two doses of measles-mumps-rubella vaccine, strengthening the integrated measles and rubella surveillance system, and developing a CRS surveillance system. This report summarizes the results of a successful adult campaign. Targeting MR vaccination appropriately and using the opportunity to strengthen surveillance for rash illness has benefits beyond accelerated rubella control and CRS prevention, including strengthening of the measles eradication program.

RESUMO

Two outbreaks of respiratory tract illness associated with prolonged cough occurring in 1998 and 1999 in New York State were investigated. A PCR test for Bordetella pertussis was primarily used by a private laboratory to confirm 680 pertussis cases. Several clinical specimens had positive culture results for B. pertussis during both outbreaks, which confirmed that B. pertussis was circulating during the outbreaks. However, testing by the New York State Department of Health reference laboratory suggested that some of the PCR results may have been falsely positive. In addition, features of the outbreak that suggested that B. pertussis may not have been the primary agent of infection included a low attack rate among incompletely vaccinated children and a significant amount of illness among patients testing PCR negative for B. pertussis. These investigations highlight the importance of appropriate clinical laboratory quality assurance programs, of the limitations of the PCR test, and of interpreting laboratory results in context of clinical disease.
