  • Much Needed Convergence of Post Approval Change Guidelines Worldwide

    Upon the initial licensure the life of a medicine or vaccines starts. An essential part of this is a continuous update through variation to the original license, known as post approval changes (PAC). These changes are done to enhance robustness and efficiency of the manufacturing process, improve QC techniques, upgrade to state-of-the art facilities and continuously update to meet regulatory and safety information. However, throughout the world there is a wide range of guidance governing PACs.  A comparison of these regulations/guidelines, requirements, and procedures for management of PACs from some key countries across the world was performed.  Our results show the lack of alignment between them and in addition also demonstrates the lack of predictability of timelines for review and approval in many countries. The latter, especially, has a considerable impact on the supply chain flexibility and by consequence may limit access for patients to that most up to date medicines and vaccines. The WHO guidelines, which are comprehensive and could represent a consensual model for alignment. Unfortunately, these WHO guidelines are still underused. Reliance on the review and approval by the health authority in country of origin, other Stringent Regulatory Authorities (soon to be WHO listed Authorities or WHO-PQ could be another way forward. These and other options or opportunities to improve the management of changes during the product lifecycle will be outlined. Ultimately, industry and regulators owe it to patients to provide and facilitate access to the most up to date versions of medicines and vaccines.

  • Clinically-approved drugs with potent antiviral activity and synergistic interactions for the treatment of COVID-19

    The ongoing COVID-19 pandemic is the result of a zoonotic transmission event, similar to previous coronavirus epidemics. Antiviral therapeutics are urgently needed to combat SARS-CoV-2 in the current pandemic and will be the first line of defense for future coronavirus epidemics during the typical lag time of vaccine development. The SARS-CoV-2 coronavirus is reliant on host cell proteins to successfully complete the viral replication cycle and our previously published SARS-CoV-2 interactome highlighted 332 host proteins that are likely to play a role in the viral life cycle, representing potential host targets for therapeutic intervention. Thus far we have screened over 800 potential antiviral drugs using an evidence-based approach, targeted to both the host and viral proteins, against SARS-CoV-2 in cell culture. In this manner we have identified over 40 compounds which inhibit SARS-CoV-2 with a sub-micromolar IC90 in vitro, with our top host-targeted antiviral drug, plitidepsin, having a sub-nanomolar IC90. Furthermore, we have identified multiple FDA-approved HCV protease inhibitors that have antiviral activity against SARS-CoV-2 and synergize with the current standard of care, remdesivir. Finally, we have tested our most potent clinically-approved host-targeted antiviral in animal models of SARS-CoV-2 infection with highly promising results that have led to ongoing COVID-19 clinical trials. Taken together, our results offer multiple clinically-approved drugs with significant potential to impact patient health in the ongoing COVID-19 pandemic and offer many insights into SARS-CoV-2 biology that can be used for the specific design of future antivirals for the treatment of coronavirus infection. Our ultimate goal is to produce a host-targeted antiviral treatment or a cocktail of synergistic viral-targeted drugs with potent efficacy that can prevent the rise of drug-resistant SARS-CoV-2 variants.

  • Perception of vaccination of filipino mothers in the NCR-area post-dengvaxia (YRF)

    Vaccine hesitancy of mothers is a significant public health concern especially after the Dengvaxia controversy in the Philippines. This cross-sectional study assessed the demographic profile, vaccination factors, and influences of Filipino mothers (n = 384) in the National Capital Region (NCR). Descriptive and inferential statistics were used to analyze the obtained data, and significant factors in vaccine hesitancy of mothers (μ = 42.12 y/o) were revealed. Factors in the demographic profile such as educational attainment (p = 0.035) and monthly income (p = 0.034) have affected their perception of vaccination. High vaccine hesitancy (20.1%) of the participants is relatively increased in the Philippines despite their relatively high level of knowledge and a positive attitude regarding vaccination. Most of the participants trust the government and pharmaceutical companies for their vaccines (p = 0.037; p = 0.002). Majority followed the recommended vaccination schedule of their child (p = 0.001) and half suppose that there are more ways for disease prevention other than vaccination (p = 0.015). Vaccine cost (p = 0.012) and accessibility (p = 0.005) also influenced the decisions of the participants. The participants show a positive perception towards vaccination despite high vaccine hesitancy prevalence. However, there remains a need for the government and health professionals to prioritize parental education not only to correct false information on vaccination but also to gain the public’s trust while improving the public health system against its fight with vaccine hesitancy.

  • Generation of a SARS-CoV-2 pseudotyped viral particle system enabling for the study of cell-types of infection and patient sera neutralisation

    Abstract:

    Background: The novel coronavirus (SARS-CoV-2) that emerged in December 2019, resulting in COVID-19, continues to affect the population, putting more pressure on healthcare systems and global socioeconomic balances. The World Health Organization declared COVID-19 a global pandemic, referring to approximately 179 million confirmed cases and 3.87 million confirmed deaths as of June 2021. Easy in vitro viral systems are required to study viral entry and sera neutralisation of the different emerging strains of SARS-CoV-2.

    Methods: The aim was to generate an HIV-1 pseudotyped virus particle (PVP) system that expresses spike protein (CoV-S2wt) and compare infectivity profiles in two different cells, 293T and 293T-ACE2. We also monitored infection in macrophages (MQ), Dendritic Cells (DCs) and Vero cells. Furthermore, we tested SARS-CoV-S2wt PVP treated with COVID-19 patient's sera to investigate neutralisation capacity.

    Results: We generated HIV-1 PVP expressing SARS-CoV-2S2 protein, which infected 293T-ACE2 cells but less efficiently 293T cells, showing the development of a virus mimicking SARS-CoV-2. This virus was successfully neutralised with patient sera generated from acute infected COVID-19 patients. The same viruses were tested for infectivity of MQ, DCs and Vero cells and where it was shown to be infectious, but to far lower levels as on 293T-ACE2 cells. These results indicate that primary cells of the immune system can be infected with SARS-CoV-2 to low levels.

    Conclusions: We have demonstrated the successful generation of an HIV-1 PVP expressing SARS-CoV-2Swt protein, which infects cells expressing the ACE2 receptor and can be inhibited with sera from COVID-19 survivors. Utilising these viruses, we demonstrate that MQ, DCs and Vero cells can be infected to low levels.
