Expediting approval for medical countermeasures to address high burden disease: an ethical justification to move beyond emergency use authorisation.

Addressing global health crises requires a receptive and expedient policy environment to minimise delays in making available potentially life-saving technologies. Over time, the policy environment has adapted to ensure that communities have expedited access to promising technologies, such as vaccines, that can mitigate morbidity and mortality. Emergency authorisations are one such policy mechanism. While these have been employed successfully for several diseases, such as influenza, Ebola and COVID-19, the policy mechanism is tied to contexts where key bodies have designated the disease an 'emergency', whereas no equivalent mechanism exists for those failing to acquire the designation (eg, malaria and tuberculosis). In this paper, we examine ethical issues associated with emergency authorisations. We argue that there is no moral difference between those diseases considered emergencies and many that fail to be designated as such with respect to impact on affected communities. Thus, tying access to an expedient policy mechanism for approval to an emergency designation is ethically unjustified-it should be based on considerations of risks and benefits, the disease burden and the values of the communities that carry those risks and not contingent on if the disease is designated an emergency. We suggest the need to further enhance the policy environment to ensure access to similar expedited approval programmes irrespective of if a disease is an emergency. Levelling the field for access to expedited approval programmes across diseases can help in moving towards achieving global health equity but is not a panacea.

Biopharmaceutical Financialization and Public Funding of Medical Countermeasures (MCMs) in Canada During the COVID-19 Pandemic.

BACKGROUND: Analysing the Canadian government's efforts to support the development of COVID-19 "medical countermeasures" (MCMs), this article seeks insights into political economy as a driver of pandemic response. We explore whether Canadian public funding policy during the pandemic involved departures from established practices of financialisation in biopharmaceutical research and development (R&D), including the dominance of private sector involvement in an intellectual property (IP) intensive approach to innovation underscoring profit, and governance opacity. METHODS: We interrogate public funding for MCMs by analyzing how much the Government of Canada (GoC) spent, how those funds were allocated, on what terms, and to whom. We identify the funding institutions, and the funds awarded between February 10, 2020, and March 31, 2021, to support the research, development, and manufacturing of MCMs, including diagnostics, vaccines, therapeutics, and information about clinical management and virus transmission. To collect these data, we conducted searches on the Internet, public data repositories, and filed several requests under the Access to Information Act (1985). Subsequently, we carried out a document-based analysis of electronically accessible research contracts, proposals, grant calls, and policy announcements. RESULTS: The GoC announced CAD$ 1.4 billion for research, development and manufacturing of COVID-19 MCMs. Fully 68% (CAD$ 959 million) of the announced public funding was channelled to investment in private sector firms. Canadian public funding showed a consistent focus on early and late stage development of COVID-19 MCMs and the expansion of biopharmaceutical manufacturing capacity. Assessing whether Canada's investments into developing COVID-19 MCMs safeguard affordable and transparent access to the products of publicly funded research, we found that access policies on IP management, sharing of clinical data, affordability and availability were not systematic, consistent, or transparent, and few, if any, mechanisms ensured long-term sustainability. CONCLUSION: Beyond incremental change in policy goals, such as public investment in domestic biomanufacturing, the features of Canadian public policies endorsing financialization in the biopharmaceutical sector remained largely unchanged during the pandemic.

Preparing for a "dirty bomb" attack: the optimum mix of medical countermeasure resources.

BACKGROUND: In radiological emergencies with radionuclide incorporation, decorporation treatment is particularly effective if started early. Treating all people potentially contaminated ("urgent treatment") may require large antidote stockpiles. An efficacious way to reduce antidote requirements is by using radioactivity screening equipment. We analyzed the suitability of such equipment for triage purposes and determined the most efficient mix of screening units and antidote daily doses. METHODS: The committed effective doses corresponding to activities within the detection limits of monitoring portals and mobile whole-body counters were used to assess their usefulness as triage tools. To determine the optimal resource mix, we departed from a large-scale scenario (60,000 victims) and based on purchase prices of antidotes and screening equipment in Germany, we calculated efficiencies of different combinations of medical countermeasure resources by data envelopment analysis. Cost-effectiveness was expressed as the costs per life year saved and compared to risk reduction opportunities in other sectors of society as well as the values of a statistical life. RESULTS: Monitoring portals are adequate instruments for a sensitive triage after cesium-137 exposure with a high screening throughput. For the detection of americium-241 whole-body counters with a lower daily screening capacity per unit are needed. Assuming that 1% of the potentially contaminated patients actually need decorporation treatment, an efficient resource mix includes 6 monitoring portals and 25 mobile whole-body counters. The optimum mix depends on price discounts and in particular the fraction of victims actually needing treatment. The cost-effectiveness of preparedness for a "dirty bomb" attack is less than for common health care, but costs for a life year saved are less than for many risk-reduction interventions in the environmental sector. CONCLUSION: To achieve economic efficiency a high daily screening capacity is of major importance to substantially decrease the required amount of antidote doses. Among the determinants of the number of equipment units needed, the fraction of the potentially contaminated victims that actually needs treatment is the most difficult to assess. Judging cost-effectiveness of the preparedness for "dirty bomb" attacks is an issue of principle that must be dealt with by political leaders.

SARS-CoV-2: Impact on, Risk Assessment and Countermeasures in German Eye Banks.

INTRODUCTION: Since the beginning of the COVID-19 pandemic there has been some debate regarding the risk of transmission through tissue transplantation and tissue banking processes. AIM OF THE STUDY: To analyze the changes that SARS-CoV-2 has caused regarding the harvesting of corneal donor tissue and eye bank activities in Germany. METHODS: A questionnaire was provided to 26 eye banks in Germany, consisting of questions about adaptations made in the screening of potential donors and the harvesting of corneal tissue following the pandemic spread of SARS-CoV-2. RESULTS: Eighteen eye banks actively reduced recruitment of donors and two banks ceased all activity. Additional diagnostic screening was performed in eight banks, using conjunctival swabs and/or nasopharyngeal swabs. In six eye banks, additional protective measures, such as FFP2 masks and/or facial shields, were implemented. Overall, a mean reduction in the number of obtained donor tissues of 17% was observed. DISCUSSION: Conjunctival and/or nasopharyngeal swabs of donors have been implemented by a minority. Reasons for not performing additional tests may be moderate sensitivity and lack of validation for postmortem use of RT-PCR testing. Also, the hazard of SARS-CoV-2 entering the corneal donor pool with subsequent transmission might be perceived as theoretical. Face shields provide a sufficient barrier against splash and splatter contamination but may be insufficient against aerosols. Additional face masks would provide support against aerosols, but it remains debatable if corneal harvesting can be considered an aerosol-producing procedure. In the future we expect to see changes in current guidelines because of a surge in scientific activities to improve our understanding of the risks involved with cornea donation in the COVID-19 pandemic, and because current practice may reduce the availability of donor corneas due to new exclusion criteria while the demand remains unchanged.

Interdependent Factors of Demand-Side Rationale for Chemical, Biological, Radiological, and Nuclear Medical Countermeasures.

The deliberate use of chemical, biological, radiological, and nuclear (CBRN) materials in war or terrorist attacks is perceived as a great threat globally. In the event of a release of CBRN agents, protection by means of medical countermeasures (MedCMs) could reduce health vulnerability. Nonetheless, for some diseases caused by these agents, innovative MedCMs do not exist and many of those that do might not be readily available. Inappropriate research and development funding and government procurement efforts can result in adverse economic consequences (eg, lost income, cost per loss of life, medical expenses) far exceeding the costs of strong and comprehensive preparedness initiatives. By illustrating factors of demand-side rationale for CBRN MedCMs, this article aims to strengthen integrity of policy-making associated with current demand requirements. Namely, an approach to inspire broader assessment is outlined by compiling and adapting existing economic models and concepts to characterize both soft and hard factors that influence demand-side rationale. First, the soft factor context is set by describing the impact of behavioral and political economics. Then, lessons learned from past public health funding models and associated collaborative access infrastructure are depicted to represent hard factors that can enhance the viability of MedCM preparedness evaluations.

Medical countermeasures during the 2018 Ebola virus disease outbreak in the North Kivu and Ituri Provinces of the Democratic Republic of the Congo: a rapid genomic assessment.

BACKGROUND: The real-time generation of information about pathogen genomes has become a vital goal for transmission analysis and characterisation in rapid outbreak responses. In response to the recently established genomic capacity in the Democratic Republic of the Congo, we explored the real-time generation of genomic information at the start of the 2018 Ebola virus disease (EVD) outbreak in North Kivu Province. METHODS: We used targeted-enrichment sequencing to produce two coding-complete Ebola virus genomes 5 days after declaration of the EVD outbreak in North Kivu. Subsequent sequencing efforts yielded an additional 46 genomes. Genomic information was used to assess early transmission, medical countermeasures, and evolution of Ebola virus. FINDINGS: The genomic information demonstrated that the EVD outbreak in the North Kivu and Ituri Provinces was distinct from the 2018 EVD outbreak in Équateur Province of the Democratic Republic of the Congo. Primer and probe mismatches to Ebola virus were identified in silico for all deployed diagnostic PCR assays, with the exception of the Cepheid GeneXpert GP assay. INTERPRETATION: The first two coding-complete genomes provided actionable information in real-time for the deployment of the rVSVΔG-ZEBOV-GP Ebola virus envelope glycoprotein vaccine, available therapeutics, and sequence-based diagnostic assays. Based on the mutations identified in the Ebola virus surface glycoprotein (GP12) observed in all 48 genomes, deployed monoclonal antibody therapeutics (mAb114 and ZMapp) should be efficacious against the circulating Ebola virus variant. Rapid Ebola virus genomic characterisation should be included in routine EVD outbreak response procedures to ascertain efficacy of medical countermeasures.

Contraception as a Medical Countermeasure to Reduce Adverse Outcomes Associated With Zika Virus Infection in Puerto Rico: The Zika Contraception Access Network Program.

The Zika Contraception Access Network established a network of 153 physicians across Puerto Rico as a short-term emergency response during the 2016-2017 Zika virus outbreak to provide client-centered contraceptive counseling and same-day contraception services at no cost for women who chose to prevent pregnancy. Between May 2016 and August 2017, 21 124 women received services. Contraception was used as a medical countermeasure to reduce adverse Zika-related reproductive outcomes during the outbreak and may be considered a key strategy in other emergencies.
