(c) The concept of redundancy in the provision of antivenoms is very well illustrated in this historical example. 2003 Apr;41(5):541-57. doi: 10.1016/s0041-0101(02)00393-8. To attain these objectives, and to follow the concept of redundancy in antivenom provision, an eclectic universe of manufacturers should be stimulated, including national, regional, and global producers with different scales of production and markets, involving public as well as private laboratories. The scale of antivenom production by each of these organizations is unclear. Laustsen AH, Mara Gutirrez J, Knudsen C, et al.

Espaol Key facts Though the exact number of snake bites is unknown, an estimated 5.4 million people are bitten each year with up to 2.7 million envenomings. Moreover, the regulation of antivenom manufacture and distribution has been deficient in many countries, hence facilitating the introduction of ineffective antivenoms that lack proper preclinical assessment and quality controls. Pros and cons of different therapeutic antibody formats for recombinant antivenom development. The history of antivenoms development: Beyond calmette and vital Brazil. Snakebite envenoming is a highly relevant public health problem on a global basis that kills and maims several hundred thousand people every year [1,2]. eCollection 2022 Dec.

Competing theories and geopolitics. This was followed in 1980 by the creation of the Instituto Nacional de Controle de Qualidade em Sade (INCQS-National Institute for Quality Control in Health). These include: (a) Assessing the magnitude of the problem on a global basis; (b) improving antivenom availability, accessibility, and affordability; (c) promoting transfer of knowledge on this topic between member states; (d) integrating control of snakebite envenoming with efforts to control other diseases; (e) improving access to treatment and rehabilitation services to affected people; (f) providing training to health professionals in the diagnosis and treatment of envenomings; (g) supporting research activities on several aspects of snakebite envenoming; (h) promoting community awareness through culturally contextualized public campaigns; and (i) fostering of cooperation and collaboration between member states, the international community, and other relevant stakeholders. There are 176 species and subspecies of snakes in southern Africa. The deficit in resources and personnel is often associated with weak managerial practices which hamper the productivity of these laboratories. This product is a lyophilized Habu antivenom produced by collecting and purifying serum from horses immunized with Habu venom and toxoid. Leave no one behind is a motto of the United Nations that reflects these goals [25]. An official website of the United States government, : For example, the polyspecific antivenom manufactured in Costa Rica and currently used in all Central American countries and in Ecuador and Saint Lucia is prepared by a mixture of venoms of Bothrops asper, Crotalus simus, and Lachesis stenophrys [34]. Consequences of neglect: Analysis of the sub-Saharan African snake antivenom market and the global context. Doctors at the hospital gave Ally Thomas antivenom, an antidote for snakebites that can save people's lives if administered quickly enough. 2015 Jul-Aug;69(4):499-510. doi: 10.5731/pdajpst.2015.01058. Likewise, ministries of health should have national regulatory agencies with the capacity of evaluate the safety and efficacy of antivenoms produced in the country or imported. Likewise, maintenance programs for equipment are limited. Follow-up all patients for signs and symptoms of delayed allergic reactions or serum sickness (e.g., rash, fever, myalgia, arthralgia). An antivenom shortage is spurring global experts to collaborate on treatment and prevention. These medicines must comply with identity, purity, safety and efficacy profiles, as requested by the current Good Manufacturing Practices (GMPs) applied to modern biopharmaceutical drugs. The possibilities for technical and professional staff to attend workshops, courses, and symposia are scant. The invaluable expertise developed in these laboratories must be harnessed and upgraded, but the lack of political and economic support for many of them during the last decades threatens their productivity and even their existence. Neutralization of four Peruvian. Likewise, the field of preclinical evaluation of antivenoms has grown and now consists of a toolkit of assays to evaluate the neutralizing scope of antivenoms, and also to substitute in vivo tests for in vitro assays within the context of the 3Rs principle (Replacement, Reduction, Refinement) [29]. This course will examine the basic and common groups of snakes in Southern Africa. Network of public antivenom manufacturing laboratories in Latin America. U.S. Customs will hold most shipments until you or your customs broker clear them. official website and that any information you provide is encrypted the contents by NLM or the National Institutes of Health. Owing to the growing financial limitations of public institutions and governments along the last decades, some of these laboratories have lagged behind in the need to update their infrastructure and to replace old equipment, with the consequent negative impact in antivenom production. Sterility and safety reports should be submitted to CBER upon receipt. Nevertheless, the ideal of health for all has continued to permeate the global health agenda, and has made its way to relevant global initiatives, such as the Millennium Development Goals (MDGs) [23] and the 2030 Agenda for Sustainable Development [24], launched by the United Nations. . As such, snakebite envenoming is a disease of the poor [3,4]. Around 81 000 to 138 000 people die each year because of snake bites, and around three times as many amputations and other permanent disabilities are caused by snakebites annually. eCollection 2022 Aug.

The political upheavals often related with changes in the governments and in the directorship of manufacturing institutions should not affect the technical continuity of the projects. Therefore, a vicious cycle of antivenom market decline has occurred, driven by the lack of resources for antivenom procurement and the low confidence of antivenom safety and efficacy. 3.5 UK Antivenom Price by Manufacturer (2015-2020) 3.6 Top 3 and Top 5 Antivenom Companies in UK, by Revenue in 2019 3.7 UK Manufacturers Antivenom Product Type 3.8 Tier 1, Tier 2 and Tier 3 Antivenom Players in UK 3.8.1 List of UK Tier 1 Antivenom Companies 3.8.2 List of UK Tier 2 and Tier 3 Antivenom Companies 4 Sights by Product 4.1 Overview Calvete J.J., Sanz K., Cid P., de la Torre P., Flores-Daz M., dos Santos M.C., Borges A., Bremo A., Angulo Y., Lomonte B., et al. Fortunately, owing to the concerted action of many stakeholders, in the last years there has been a growing global awareness on the impact of this tropical disease, and significant steps forward have been taken for attending to it. In the Americas, the first public institution in charge of manufacturing antivenoms was Instituto Butantan, created in 1901 in So Paulo, Brazil [26]. Rojas G., Jimnez J.M., Gutirrez J.M. Bethesda, MD 20894, Web Policies Nevertheless, in the previous decades, many of these laboratories have faced serious challenges to keep up with the necessary investment for their development, and some of them currently have problems at various levels, in large part owing to the limitations suffered by public health institutions, as described above. Your broker should clear these parcels. By the 1970s, a multinational pharmaceutical company (Syntex do Brasil) was providing the majority of vaccines and antivenoms being used in Brazil. 500 units or more of botulism type A, B, and E antitoxin 200 units or more of botulism type F antitoxin. The strengthening of public laboratories in various parts of the world is a safeguard for guaranteeing antivenom availability in the midst of ups and downs associated with a market economy. Global manufacturers produce and distribute antivenoms to several continents. The heterogeneity of this universe involves not only the volume of production and scope of distribution, but also differences in some technical aspects of antivenom design and production. Accessed June 13, 2022. https://cdn.who.int/media/docs/default-source/biologicals/blood-products/document-migration/antivenomglrevwho_trs_1004_web_annex_5.pdf?sfvrsn=ef4b2aa5_3&download=true 3. It is highly stable thanks to its lyophilized form, and can be stored for up to ten years. The production of antivenoms at a national level is coordinated between the Ministry of Health and the four manufacturing laboratories (Instituto Butantan, FUNED, Instituto Vital Brazil, and the Centro de Pesquisa e Produo em Imunobiolgicos (CPPI-Center for Research and Production of Immunobiologicals). The adoption of snakebite envenoming as a NTD by the WHO [5] has resulted in the conformation of a WHO working group that is preparing a strategic plan with short-, medium-, and long-term objectives aimed at drastically reducing its impact [6]. According to the WHO webpage on antivenoms [], there are 46 laboratories which produce animal-derived antivenoms in the world, although it is likely that this number has changed over the last years.The majority of these laboratories are located in Asia and the Americas, followed by Europe, whereas fewer manufacturers are . Simultaneously, in 1985, a large investment by the federal government was implemented with the goal of making Brazil self-sufficient in antivenoms and several vaccines. Regarding Crotalus sp venoms, two different patterns of venom composition have been described: type I venoms have a predominance of hemorrhagic metalloproteinases over the neurotoxic PLA2 dimer crotoxin, whereas type II venoms has a predominance of crotoxin and low amounts of metalloproteinases [42,43]. Public antivenom manufacturing laboratories constitute an invaluable asset for ensuring the global availability of antivenoms. The name of each product, the name and address of the manufacturer, the species against whose venom the antivenom is claimed to be effective, and when available, the lot number(s) of the product . Several polyspecific and few monospecific antivenoms are manufactured in the region, with two laboratories (one public and one private) in Argentina, Colombia, and Mexico, four public laboratories in Brazil, and one public laboratory in Bolivia, Peru, Venezuela, and Costa Rica [17,19].

The general scheme for producing snake antivenoms has undergone few changes since its development more than a century ago; however, technological innovations have been introduced in the manufacturing process. logo are trademarks of Protherics UK Ltd. Apple and the Apple logo are trademarks of Apple Inc., registered The snakebite problem and antivenom crisis from a health-economic perspective. Industrial production of snake antivenoms comprises several stages, such as: 1) production of reference venom pools, 2) production of hyperimmune plasma, 3) purification of the antivenom immunoglobulins, 4) formulation of the antivenom, 5) stabilization of the formulation, and 6) quality control of in-process and final products. In the case of venoms of high medical impact in the region, such as those of Bothrops asper, B. atrox, B. jararaca, B. neuwiedi (diporus), and B. neuwiedi (mattogrossensis), polyspecific antivenoms produced in Argentina, Brazil, Bolivia, Peru, Colombia, Costa Rica, and Mexico are effective in the neutralization of lethal, hemorrhagic, coagulant, and myotoxic effects of these venoms, albeit with different values of Median Effective Doses (ED50) [34,40]. This requires a variety of interventions tailored to the needs of manufacturers, both public and private, in order to improve their performance. sharing sensitive information, make sure youre on a federal This is an example of redundancy in the production and provision of antivenoms, an experience that could be replicated in other regions of the world. For this, antivenom manufacture must be re-invigorated by initiatives aimed at augmenting provision of safe and effective products. Moreover, there is a deficit in programs aimed at the permanent training and qualification of the existing personnel, which limits innovation. Likewise, an increased availability of these products should be linked to interventions for improving their accessibility in remote rural regions where envenomings occur, and to train health personnel in the correct diagnosis and management of snakebite envenoming. Accessibility Overall, the public sector has to play a leading role in this field, as well as in other aspects of the control of snakebite envenoming. MeSH It also illustrates that despite the exodus of manufacturers in the 1970s and 1980s, willing producers do exist and they possess substantial unutilised production . "Capable and willing private manufacturers can . Improving antivenom availability and accessibility: Science, technology, and beyond. [19,31]).

Heterologous Expression and Immunogenic Potential of the Most Abundant Phospholipase A. Plasma processing groups should evaluate the steps in their fractionation protocols in order to optimize them. According to the World Health Organization, there are 46 laboratories producing animal-derived antivenoms, of which 31 (many of them in Latin America) are government-owned. Diverse stakeholders, including public antivenom laboratories, need to work in cooperative schemes to ensure the availability of these antivenoms. Foreign manufacturers should include the BB-IND number on all shipping labels. This has caused a drop in the demand and sales of these products, which forces manufacturers to increase the price of antivenoms, hence contributing to a reduced demand [12,13,14].

Williams D.J., Habib A.G., Warrell D.A. Hence, in the cases of countries that do not manufacture their own antivenoms (Uruguay, Paraguay, Ecuador; the Guyanas, Panama, Nicaragua, El Salvador, Honduras, and Guatemala), or those that may have deficits in their own supplies of antivenoms, several products from other countries can be used, thus constituting a scenario of regional self-sufficiency in antivenom supply. Apply to the Center for Biologics Evaluation and Research (CBER), for a BB-IND number. Current research into snake antivenoms, their mechanisms of action and applications. There is an urgent need to increase the availability of antivenoms globally, by enhancing the capacity of current antivenom producers, as well as promoting the introduction of new manufacturers to this field. Public antivenom manufacturing laboratories exist in Argentina (ANLIS-Administracin Nacional de Laboratorios e Institutos de Salud); Brazil (FUNED, Fundao Ezequiel Dias; Instituto Butantan; Instituto Vital Brazil; CPPI, Centro de Pesquisa e Produo em Imunobiolgicos); Bolivia (INLASA, Instituto Nacional de Laboratorios de Salud); Peru (INS, Instituto Nacional de Salud); Colombia (INS, Instituto Nacional de Salud); Venezuela (BIOTECFAR, Universidad Central de Venezuela); Costa Rica (ICP, Instituto Clodomiro Picado, Universidad de Costa Rica); Mexico (BIRMEX, Laboratorio de Biolgicos y Reactivos de Mxico). There are notorious contrasts in the political will of governments of countries in the support of antivenom laboratories. 2023 Apr 17;18:100158. doi: 10.1016/j.toxcx.2023.100158. For a detailed account on these developments, see Refs. In summary, a culture of creativity and innovation, associated with permanent improvement of the qualification of staff, is mandatory for the strengthening of these manufacturing facilities. For example, polyspecific antivenoms from various manufacturers have been used in Central American countries, as well as in Colombia, the Guyanas, Paraguay, and Ecuador. African snakes. 33 other terms for antivenom- words and phrases with similar meaning This product is a lyophilized diphtheria antitoxin produced by collecting and purifying plasma from horses immunized with diphtheria toxoid.

Clinical studies of the effectiveness and safety of antivenoms. doi: 10.1371/journal.pntd.0010643. The present review focuses on the tasks to strengthen the public antivenom-manufacturing laboratories as key stakeholders in the global strategy to confront snakebite envenoming. Attention to these aspects should pave the way for a systematic improvement of public laboratories to the regional and global availability of safe and effective antivenoms. Approximately 50 antivenom manufacturers are currently listed as active by WHO (WHO Website, a). 2017;70(2):233-244. Likewise, an active research program in public universities and institutes was strengthened, including basic research in the biochemistry, toxicology, and immunology of animal venoms, as well as epidemiological and clinical studies on envenomings and their treatment. At the same time, a dynamic networking activity should be fostered between manufacturing and quality control laboratories, regulatory agencies and research groups in universities and other institutions. Some antivenoms may be polyspecific and have a wide geographical range of efficacy, whereas others may have a more restricted regional scope, or be directed against the venom of a single snake species, depending on the particular needs of countries. The majority of antivenoms include F(ab)2 fragments as the active substance, by fractionating hyperimmune plasma with a combination of pepsin digestion and salting out procedures. As stated in the Introduction, the global efforts to reduce the impact and suffering caused by snakebite envenomings demand a multi-component, multi-stakeholder strategy involving international and national public health authorities, the scientific and technological research community, antivenom manufacturers and quality control laboratories, national regulatory agencies, university schools in charge of medical and nursing education, local community organizations, non-governmental organizations (NGOs) and foundations that support health programs, health advocacy groups, and others, in order to achieve the goals included in the World Health Assemblys resolution of May 2018 on snakebite envenomings and in the WHO strategic plan. Confronting the neglected problem of snake bite envenoming: The need for a global partnership. In general, the public sector should play a leading role, in antivenom availability and other aspects as well, within the global struggle to reduce the mortality and morbidity caused by snakebite envenoming. The site is secure. The term crotalid is used to describe the Crotalinae subfamily (formerly known as Crotalidae) of venomous snakes which includes rattlesnakes, copperheads and . It was responsible for defining the most adequate combination of venoms to be used in the manufacture of antivenoms, the standardization of the potency tests for assessing antivenom efficacy, and the establishment of reference venoms for the most important snake species, to be used by manufacturers and quality control laboratories.

(b) The public health authorities and, in general, governments should have a leading role for ensuring the availability and accessibility of antivenoms in public health systems. Snake envenoming: A disease of poverty. This brief historical account provides several lessons: (a) The dependence of a single manufacturer for the provision of an essential medicine, such as antivenom, puts the public health system of a country in a vulnerable position, as this Brazilian experience shows. Recurrent coagulopathy due to envenomation and requiring additional treatment may occur. As a further development, the 71st World Health Assembly, celebrated in Geneva in May 2018, adopted a resolution proposed by 22 countries from five continents, with the leadership of Costa Rica and Colombia, aimed at addressing the burden of snakebite envenoming on a global basis. CroFab Crotalidae Polyvalent Immune Fab (Ovine) is a sheep-derived antivenin indicated for the management of adult and pediatric patients with North American crotalid envenomation. eCollection 2023 Jun. Gutirrez J.M., Theakston R.D.G., Warrell D.A. CroFab Crotalidae Polyvalent Immune Fab (Ovine) is a sheep-derived antivenin indicated for the management of adult and pediatric patients with North American crotalid envenomation. This trend has to be reverted by establishing permanent training programs, adapted to the needs of the staff of manufacturing laboratories. CroFab. Other products are made of whole IgG molecules, usually obtained by caprylic acid precipitation of non-immunoglobulin plasma proteins, and one manufacturer produces Fab antivenoms by digesting the immunoglobulins from ovine plasma with papain [18]. A statement to the effect that, in the event the product is administered, a complete case report will be submitted to the Director, CBER. Likewise, the stability of key technical staff is of utmost importance for guaranteeing the sustainability of the projects. This wealth of information should be harnessed to evaluate the design of the most appropriate venom mixtures used for antivenom production, and to establish novel combinations for new antivenoms to be developed. It includes updated range maps of all medically important venomous snakes, other relevant information, and an integrated antivenom products database. Across the border in . For example, the concept of redundancy may apply to the combination of private and public, as well as national or international, manufacturing laboratories, and the variable scales of needs and production may demand different approaches, i.e., some countries do not have the conditions to develop their own antivenom-producing laboratories, hence having to rely on manufacturers from abroad.

Snakebite envenomation turns again into a neglected tropical disease! Download Free Sample Anti-venom Market Analysis The anti-venom market is expected to register a CAGR of nearly 8.54% during the forecast period. As an example, the introduction of caprylic acid fractionation instead of ammonium sulfate precipitation in the preparation of whole IgG antivenoms should be considered [30]. They have provided a long standing contribution to the control of snakebite envenoming through the supply of antivenoms for their own countries and, in some cases, for other countries in the region. 8600 Rockville Pike The concept of health as a commodity, within the context of a market-driven economy, has been fostered, together with trends in developing countries governments to reduce the public expenditure in health and other social services (for a detailed description of the ups and downs of global public health in the last decades, see Ref. On the other hand, the bothropic antivenom manufactured by Brazilian laboratories uses a mixture of venoms of Bothrops jararaca, B. jararacussu, B. neuwiedi, B. alternatus, and B. moojeni [34], whereas the bothropic antivenom produced in Peru is based on the immunization of horses with the venoms of Bothrops atrox, B. barnetti, B. pictus, B. brazili, and Bothrocophias hyoprora [34].

When reconstituted with 20 mL of the attached diluent, the product contains the following active ingredients per mL: The .gov means its official.Federal government websites often end in .gov or .mil. INCQS detected important flaws and deficiencies in the biological products, including antivenoms, and the production of immunobiologicals was halted. It is highly stable thanks to its lyophilized form, and can be stored for up to ten years. In Latin America, the network of public antivenom manufacturing laboratories has established an informal dynamics of inter-group consultations on specific aspects, which has become a useful mechanism for trouble shooting in antivenom production. It will appear at your institution with no customs stamps indicating clearance. Accordingly, they should be strengthened by national and regional programs.

A key component in this global agenda has to do with the improvement in the availability, accessibility, and affordability of antivenoms. Thus, antivenoms produced in Argentina, Brazil, Peru, Colombia, Venezuela, and Mexico using type II venoms are effective in the neutralization of neurotoxic Crotalus sp venoms in South America and Mexico, whereas antivenoms prepared by using type I venoms are effective in Central America and against non-neurotoxic venoms in North America [15,43,44,45,46]. Particular thanks are due to Hui Wen Fan (Instituto Butantan, Brazil), the colleagues of the Latin American network of public antivenom manufacturers, and Guillermo Len, Alberto Alape-Girn, and other colleagues at Instituto Clodomiro Picado, University of Costa Rica. An innovative approach is necessary in order to stimulate a steady growth in antivenom supply by (a) increasing the number of manufacturers worldwide through a policy of incentives; (b) elevating the volume of production by current and new manufacturers; (c) improving the quality of antivenoms by international cooperation networks and technology transfer schemes; (d) strengthening the national regulatory agencies to ensure that only appropriate antivenoms are introduced; (e) establishing financial programs for the consolidation of antivenom manufacturers; (f) introducing novel purchasing schemes that would favor a more stable market and create stimuli for manufacturers to increase their production; and (g) generating international cooperation platforms between antivenom manufacturing laboratories, research groups, health advocacy groups and foundations, and national and regional health authorities to improve antivenom availability and accessibility. Overall, modern managerial and organizational procedures should be implemented in order to maximize the use of available resources. Therefore, these antivenoms are relevant not only in the countries where they are manufactured and in those where related snake species are distributed, but they are also highly valuable in countries where exotic snakes are imported for private use, research, or exhibits, and antivenoms are required in the event of an envenoming. Aspects such as estimation of production costs, purchasing and maintenance programs, administration of inventories, organization of the flow of activities, efficient allocation of staff in the production departments, distribution and marketing of antivenoms, and quality assurance programs need to be introduced, evaluated, and improved aiming at increasing the efficiency of antivenom manufacture. These three public manufactures developed over the next decades; however, at some point in the second half of the 20th century there was a reduction in public investment and innovation in this antivenom-manufacturing industry. Accessibility The appropriate selection of personnel in charge of managerial roles is of key relevance, as well as the differentiation of the profiles and suitability of people selected for managerial roles and those in charge of the more technical functions in antivenom manufacture. Antivenom; Envenomation; Industrial biotechnology; Snake; Venoms. An Introduction. One aspect that requires urgent attention in these institutions is the implementation of GMPs at all levels in the chain of antivenom production. Report of a WHO workshop on the standardization and control of antivenoms. Some manufactures have made significant investments in their infrastructure and equipment, as well as in the training and upgrading of the qualifications of their personnel, fully complying with GMPs. Romero-Giraldo LE, Pulido S, Berro MA, Flrez MF, Rey-Surez P, Nuez V, Pereaez JA. Likewise, antivenoms against the colubrids Dispholidus typus and Rhabdophis tigrinus, and against sea snakes (Elapidae) are produced in South Africa, Japan, and Australia, respectively [17]. BTG Specialty Solutions Center is a trademark of BTG International Ltd. SnakeBite911 and the snakehead An example was the development of a Pan-American Micrurus antivenom by Instituto Clodomiro Picado, with the support of PAHO, during the 1970s [47]. Antivenoms are included in the WHO list of essential medicines [8]. This survey of antivenom manufacturers highlights the paucity of antivenom products for sub-Saharan Africa and the unhelpful variability that exists within the current industry. It can purchased directly from the manufacturers - the South African Vaccine Producers. Some manufacturers, mostly located in the public sector, produce antivenoms only for their own countries (national manufacturers), whereas others distribute antivenoms not only for their country, but also for neighboring countries (regional manufacturers), and few laboratories produce and distribute antivenoms to countries located in several continents (global manufacturers) [11] (Figure 1).
