  A New Layer of Medical Preparedness to Combat Emerging Infectious Disease

  DARPA has selected five teams of researchers to support PREventing EMerging Pathogenic Threats (PREEMPT), a 3.5-year program first announced in January 2018 to reinforce traditional medical preparedness by containing viral infectious diseases in animal reservoirs and insect vectors before they can threaten humans. Through studies in secure laboratories and simulated natural environments, the PREEMPT researchers will model how viruses might evolve within animal populations, and assess the safety and efficacy of potential interventions. Autonomous Therapeutics, Inc., Institut Pasteur, Montana State University, The Pirbright Institute, and the University of California, Davis, lead the PREEMPT teams. “DARPA challenges the PREEMPT research community to look far left on the emerging threat timeline and identify opportunities to contain viruses before they ever endanger humans,” said Dr. Brad Ringeisen, the DARPA program manager for PREEMPT. “One of the chief limitations of how infectious disease modeling is currently conducted is that it forecasts the trajectory of an outbreak only after it is underway in people. The best that data can do is inform a public health response, which places the United States in a reactive mode. We require proactive options to keep our troops and the homeland safe from emerging infectious disease threats.” According to the World Health Organization (WHO), approximately 60 percent of emerging infectious diseases reported globally are zoonoses, meaning that they were initially diseases of animals and at some point became capable of infecting people. Zoonotic diseases are responsible for millions of human deaths every year, and the scope of the challenge is increasing due to the densification of livestock production, human encroachment into natural spaces, and upward trends in globalization, temperature, and population. Ebola is a high-profile example of a zoonotic disease. Despite being relatively difficult to spread — requiring direct contact with fluids from infected organisms — a string of outbreaks over the past five years has highlighted the threat it could present once established in densely populated areas. Researchers express even greater concern over the pandemic potential of new strains of the influenza virus and other airborne pathogens. Even in the United States and its territories, where viruses do not frequently emerge directly from animal reservoirs, vector-borne transmission of zoonoses such as West Nile virus disease is on the rise. The 2018 U.S. National Biodefense Strategy directs that it is essential to detect and contain such bio-threats, adopting a proactive posture to improve preparedness while also assessing and managing any biosecurity risks related to possible interventions. “The health of the American people depends on our ability to stem infectious disease outbreaks at their source, wherever and however they occur,” the document states. For the Department of Defense, that obligation extends to protection of deployed service members, who often operate in countries that are “hot spots” for emerging viruses yet lack robust public health infrastructure. The teams DARPA selected for PREEMPT comprise multidisciplinary researchers who bring expertise and field experience from around the world, some of whom represent institutions from nations at high risk from emerging infectious disease. Institutions participating as sub-contractors to DARPA receive funding from the lead organizations except as otherwise noted. The PREEMPT teams proposed to model specific diseases to assess the risk of spillover from animals into humans, identify key bottlenecks in the process as opportunities for intervention, and develop and assess novel, animal- or insect-focused interventions with built-in safety switches to prevent cross-species jump. The teams will collect samples from animal reservoirs in the field for analysis in secure, bio-contained facilities; some teams will also conduct analysis on existing banked samples and datasets. DARPA is not funding the release of PREEMPT interventions into the environment. Autonomous Therapeutics, Inc., under principal investigator Dr. Ariel Weinberger, leads a team made up of CSIRO Australian Animal Health Laboratory; Navy Medical Research Unit-2, funded directly by DARPA; University of California, Los Angeles; University of Chicago Medical School; and University of Texas Medical Branch. The team will study air-borne highly pathogenic avian influenza virus in birds and small mammals, and tick-borne Crimean-Congo hemorrhagic fever virus. The Center for Comparative Medicine and the One Health Institute at the University of California, Davis, under principal investigator Dr. Peter Barry and co-PI Dr. Brian Bird, respectively, lead a team made up of the Leibniz Institute for Experimental Virology; Mount Sinai School of Medicine; Rocky Mountain Laboratories of the National Institutes of Health (NIH), to be funded directly by DARPA; The Vaccine Group, Ltd., a spin-out of University of Plymouth; University of Glasgow; University of Idaho; and University of Western Australia. The team will examine Lassa virus spillover from rodents, and study Ebola virus in rhesus macaques. The Institut Pasteur, under principal investigator Dr. Carla Saleh, leads a team made up of Institut Pasteur International Network partners in Cambodia, Central African Republic, France, French Guiana, Madagascar, and Uruguay; Latham BioPharm Group; and Virginia Polytechnic Institute and State University. The team will study several mosquito-borne arboviruses, which refers broadly to animal or human viruses transmitted by insects, as well as mosquito-specific viruses that could interfere with arbovirus infection in the insect vector. Montana State University, under principal investigator Dr. Raina Plowright, leads a team made up of the Cary Institute of Ecosystem Studies; Colorado State University; Cornell University; Griffith University; Johns Hopkins University; NIH's Rocky Mountain Laboratories, funded directly by DARPA; Pennsylvania State University; Texas Tech University; University of California, Berkeley; University of California, Los Angeles; and University of Cambridge. The team will study henipavirus spillover from bats. The henipavirus genus of viruses contains multiple biothreat agents as categorized by NIH and the Centers for Disease Control and Prevention (CDC). The Pirbright Institute, under principal investigator Dr. Luke Alphey, leads a team made up of the University of Nottingham and the University of Tartu. The team seeks to disrupt mosquito transmission of flaviviruses, which include Dengue fever, West Nile, and Zika viruses. Modeling and quantification are as important as new experimental technologies in preventing cross-species jumps. The results from modeling will inform when, where, and at what levels such interventions could be applied to achieve the greatest health benefits. Interventions under consideration include animal- or insect-targeted vaccines, therapeutic interfering particles, gene editors, and indirect approaches informed by environmental and ecological factors that affect how viruses are spread — for instance, understanding the environmental stressors that drive bats into closer contact with humans and devising mitigating options to reduce the likelihood of that contact. The research teams' approaches each come with a unique set of potential benefits and challenges, and the teams are responsible for assessing and demonstrating to DARPA the safety, efficacy, stability, and controllability of their proposed interventions. In the future, these considerations could factor into decisions by the ultimate end users — communities, governments, and regulators — on which strategies to pursue to prevent new zoonoses. DARPA and the PREEMPT teams receive guidance from independent expert advisors in the ethical, legal, social, and regulatory aspects of the life sciences. These individuals include Dr. Claudia Emerson, director of the Institute on Ethics & Policy for Innovation at McMaster University; Dr. Matt Kasper, legislative liaison for the U.S. Navy's Bureau of Medicine and Surgery, and a former deputy director of field laboratory operations at the Naval Medical Research Center; and Dr. Steve Monroe, associate director for Laboratory Science and Safety at the CDC, and a former deputy director of the CDC's National Center for Emerging and Zoonotic Infectious Diseases. The teams also benefit from established relationships with local universities, communities, and governments based on prior or ongoing research. These relationships will facilitate initial field collection and help to familiarize stakeholders with PREEMPT technologies as they are being developed. DARPA is also beginning outreach to the WHO as a potential avenue for future transition of PREEMPT technologies. DARPA intends that PREEMPT teams will perform fundamental research and publish results for review by the broader scientific community. https://www.darpa.mil/news-events/2019-02-19

  What the defense industry is seeing and saying about the election

  By: Joe Gould WASHINGTON ― Anyone will tell you this is the most important election in U.S. history ― unless they happen to run a major American defense firm. In earnings call after earnings call, defense industry executives projected calm ahead of Tuesday's election, mainly because they see the coronavirus pandemic carrying greater uncertainty (especially for firms with commercial aviation businesses). But another reason is that, despite wide projections of flat 2021 defense budgets no matter who controls the White House, industry is confident in the Pentagon's commitment to modernization. “We continue to believe that bipartisan support for defense spending will endure and that our portfolio is well-aligned to support our National Defense Strategy,” Northrop Grumman CEO Kathy Warden said in remarks typical of third-quarter earnings calls last week. “While we plan for various budget scenarios, defense spending is largely threat-driven and today's threat environment warrants a strong defense. Emerging threats are intensifying, and we believe both political parties are committed to effectively countering these threats.” If defense firms are upbeat, then Wall Street seems skeptical, with pure-play defense firms down this year and lagging the stock market, said Capital Alpha Partners' aerospace and defense analyst Byron Callan. Partisan gridlock, he noted, is what led to the budget caps that bedeviled federal budgeting for the last decade. “You could argue that some of this underperformance is related to concerns about what the election's outcome could be. Even if the president wins, no one's predicting the House will flip, and then you'll still have gridlock in Congress,” Callan said. “Let's say there's a 50-50 split in the Senate. Things can get pretty sporty.” Defense executives were comfortable making warm predictions about 2021, but the lack of comment about 2022 and 2023 was telling, said Callan. Also, Pentagon officials have warned they will have to tap modernization and readiness funds if Congress does not appropriate about $10 billion for defense contractors' coronavirus-related expenses. So why didn't any CEOs use their earnings calls to amplify that message? “That was one of the dogs that didn't bark here. Either industry doesn't see it as an issue, or that it's inevitable it's not going to happen," Callan said. With Democrats readying to debate steep defense cuts if they sweep the election, the expectation is that swollen national deficits ― driven by pandemic aid and Republican-led tax cuts ― will pressure the defense budget downward. But industry is banking on Washington's drive to prepare militarily for a rising China, a disruptive Russia and an unpredictable North Korea. “Whether it's flat with a little bit of rise or flat with a little bit of fall may depend on the election, but I think that's a fairly narrow space you're working in politically, given the deficit and the threat vectors,” Bill Lynn, the CEO of defense and aerospace conglomerate Leonardo DRS, said in an interview. Lynn is a former deputy defense secretary and Raytheon lobbyist. Though there's been speculation Democrats would cut defense spending, former vice president Joe Biden, who is running against Republican President Donald Trump, would face pressure not to for economic and political reasons, said Michael Herson, president and chief executive at American Defense International, a defense lobbying firm. (Biden has said, if elected, he doesn't foresee major defense cuts.) “The first thing that Biden's going to worry about is COVID and the economic recovery,” Herson said in an interview. “So do you really want to touch defense spending, and add to your economic woes ― because it increases unemployment ― in the first year of your presidency?” Defense Secretary Mark Esper has warned that a flat budget will force the armed services to make budgetary trade-offs and likely cuts to legacy programs. But the Pentagon has also communicated a commitment to modernization, and that's part of industry's confidence. In September, Northrop won a $13.3 billion award for the Ground Based Strategic Deterrent program, the U.S. Air Force's effort to replace the LGM-30G Minuteman III intercontinental ballistic missile. But some Democrats have attempted to defund it, and investors grilled executives about the program's post-election survival prospects ― and those of Northrop's B-21 Raider. Warden, Northrop's CEO, argued the nuclear triad becomes more of a budgetary priority when conventional military forces are under pressure. “So we're confident that a new administration would recognize that value and continue to support the modernization efforts that are well underway for both GBSD and B-21,” she said. The Pentagon over recent years has oriented itself toward technological competition with China, with related investments in artificial intelligence, next-generation networks, cybersecurity and space. Companies did not see signs of that momentum reversing. “The government doesn't pivot on a dime,” Booz Allen Hamilton's chief financial officer, Lloyd Howell Jr., told investors. “And a lot of the programs that we currently support ... are increasingly tied to their missions, which is politically agnostic.” The CEO of infrared imaging maker FLIR Systems, Jim Cannon, acknowledged there will be “top-line pressure on the budget ... no matter what happens with the election,” but he put stock in Army leaders' assurances that the service must remedy long-underfunded modernization efforts. “The message that was sent out to industry loud and clear is that, after four decades largely without significant modernization transformation, now is the time,” Cannon said. “And if we look at the priorities that we're aligned against and the work that we've been doing for the past two years, we think we're well positioned there. But look: I agree there's a lot of uncertainty, a lot of work yet for us to do, but that's our perspective right now.” When asked, L3Harris downplayed how a drawdown from Afghanistan ― which Trump and Biden both favor ― or hypothetical cuts to end strength would impact the sales of radios or night vision goggles. “We're not even 40 percent through the modernization ramp with radio. So even if end strength comes down, as I expect it likely will, I don't think it's going to affect the growth rate in our radio business,” said CEO Bill Brown, arguing that night vision goggles and radios had “under-penetrated the force.” “So if anything, reduced end strength might actually free up some dollars to be put onto modernization investments that really affect a broad part of our business,” he added. Executives at companies without a stake in a specific major platform had a good story to tell, and several pointed to investments in cybersecurity or artificial intelligence. Leonardo DRS' Lynn said the firm's investments in communications, sensors and computing systems had made it “ambidextrous." "We can go in any direction,” he said. “The larger companies have greater exposure across the breadth of the defense budget. We're more in targeted areas and haven't got broad exposure. “We're in Army sensors, satellite communications; we're in 10 or 12 segments. We can be targeted, and frankly in a flat budget environment, that ability to target's important to grow at all.” https://www.defensenews.com/congress/2020/11/02/what-the-defense-industry-is-seeing-and-saying-about-the-election/
