In this regular feature on Breakthroughs, we highlight some of the most interesting reads in global health research from the past week. This week, the White House released President Obama’s much-anticipated budget request for fiscal year (FY) 2015. The budget request has mixed results for federal agencies that conduct global health research—including the Centers for Disease Control and Prevention, the Department of Defense, the US Food and Drug Administration, the National Institutes of Health, and the US Agency for International Development (USAID). Pharmaceutical company Janssen announced that SIRTURO® (bedaquiline)—a new drug for the treatment of multi-drug resistant tuberculosis (TB)—has been granted conditional approval by the European Commission. The drug was approved for use as part of an appropriate combination regimen for pulmonary multi-drug resistant TB in adult patients. USAID has released its 2013 report to Congress—Health-Related Research and Development Progress Report. The report provides an update on the agency’s global health research and development (R&D) portfolio, specifically highlighting certain technologies and disease areas. The Kaiser Family Foundation has pulled together several news sources reports on research findings presented at the Conference on Retroviruses and Opportunistic Infections taking place in Boston this week.

Yesterday, the White House released President Obama’s much-anticipated budget request for fiscal year (FY) 2015. After hearing that the budget would be released in two phases, we weren’t sure what level of detail or clarity to expect from the top-line numbers. As it turns out, the message is murky—for now. Below are some initial takeaways on the budget proposal’s impact on global health research and development (R&D). State and USAID Global Health Programs While funding for the overall 150 international affairs account remained fairly stagnant compared with FY 2014, funding for the State Department’s global health programs—which fund most global health R&D at the US Agency for International Development (USAID) and the State Department—took a concerning downward shift, falling by 4.6 percent overall. The Maternal & Child Health, Tuberculosis, and Global HIV and AIDS programs that fund research for many new global health tools all saw decreases to varying degrees when compared with the levels that Congress just approved for them in its FY 2014 budget agreement. There were a few ‘winners’—a relative term only; USAID’s Malaria and Family Planning programs saw small increases, and GAVI—which works to scale up currently available vaccines—saw its request increased by $25 million over FY 2014. As many in the community have voiced, the flat-funding of the President’s Emergency Plan for AIDS Relief—coupled with a possible $300 million decrease in the US’s contribution to the Global Fund to Fight AIDS, Tuberculosis, and Malaria—is disappointing, if not unexpected. Funding for the State Department’s global health programs—which fund most global health R&D at the US Agency for International Development (USAID) and the State Department—took a concerning downward shift, falling by 4.6 percent overall. Although these cuts are concerning, the President’s budget request did indicate that the administration is aware of the need for sustained global health R&D programming and recognized the important role that USAID plays in fostering innovation. The President requested $146.3 million for the new Global Development Lab at USAID, which “will consolidate and expand USAID's efforts in science, technology, innovation and partnerships, creating a world-class capability to discover, incubate, test, and scale transformational solutions to the greatest development challenges that we face today.” However, according to the budget justification text, only about $5 million of this funding will go to global health programs.   Global Health R&D at NIH, CDC and FDA The President requested $30.2 billion for funding at the National Institutes of Health (NIH), a slight increase from 2014 appropriations levels of $29.9 billion, but still lower than the President’s request for FY 2014—continuing a troubling decline. It is estimated that NIH’s funding has decreased 15 percent since FY 2004. Within the NIH, the National Institute of Allergy and Infectious Diseases was funded at $4.423 billion, a 3.4 percent decrease from the President’s request for 2014, but a slight increase from the 2014 appropriated budget of $4.359 billion. The National Center for Advancing Translational Science saw a slight cut from FY 2014 appropriations and previous requests, while the National Institute of Child Health and Human Development and the Fogarty International Center were essentially flat-funded. There was potentially better news for global health R&D funding at the Centers for Disease Control and Prevention (CDC). The President requested a total of $464 million for CDC’s Center for Global Health—a significant increase over FY 2014. CDC’s Center for Emerging Zoonotic and Infectious Diseases also received a welcome increase. Both of these CDC centers are involved in the new Global Health Security Agenda programming. While the budget text says that the President requested $45 million for the new initiative, it’s not yet clear where this funding will come from. In more positive news, the President also requested just over $4.7 billion for the US Food and Drug Administration (FDA), allaying fears that the strong FY 2014 funding ($4.3 billion) would not be continued. The funding also assumes $2.612 billion in user fee income. Opportunity, Growth and Security Initiative Adding to the opaque nature of several parts of the global health and science accounts within the President’s budget request is the new $56 billion Opportunity, Growth and Security Initiative. Funds in this category include the $300 million that would go to the Global Fund if other nations are able to increase their own commitments, as well as other funding that would go to NIH and the Science, Technology, Innovation and Partnerships (STIP) in Development program via the new Global Development Lab at USAID. It’s still unclear whether this money will be allocated as stated, and many in the global health community are concerned that it would draw funds away from other health-related programs that have already been flat-funded or seen cuts. While we’re still waiting for more figures for NIH and the Department of Defense’s global health R&D programs, and details from additional budget justification documents—it’s clear that Congress has its work cut out for it in protecting global health R&D programming across the US government. When the appropriations committees from the House and Senate develop their own proposals later this spring, they should work to sustain and protect global health research and product development at USAID, CDC, NIH, FDA and the Defense Department in order to keep up the fight against global health diseases.  

In this regular feature on Breakthroughs, we highlight some of the most interesting reads in global health research from the past week. Writing in The Lancet Global Health Blog, GHTC member Drugs for Neglected Diseases initiative (DNDi) highlights the need to fill research gaps for the development of global health tools for neglected diseases and how open access to data can be one way solve this problem. DNDi has created a public data-sharing page to provide freely accessible datasets from clinical studies. By re-engineering a chain of amino acids in one type of dengue virus, scientists could have discovered a new path toward developing a vaccine against the disease. This new technique has the potential to impact the development of other diseases, including HIV and AIDS. Increasing resistance to insecticidescontinues to become an increasing threat to the effectiveness of malaria vector control. A new study shows that a DNA-based resistance marker in mosquitos could provide a tool to understand the evolution of resistance and aid in the development of resistance management strategies. Scientists have found a new way to reduce the cost of administering the Meningitis A vaccine—MenAfriVac—by half. Researchers in Benin found that storing the vaccine in chains up to 40 degree Celsius was just as effective as storing in colder conditions of two to eight degrees Celsius. The findings could provide a way to lower the cost of the vaccine because the costs associated with refrigeration will not need to be included in the final cost.

Most of us know what it’s like to be bitten by a mosquito. For those of us in non-malarious countries, the itchy sensation afterward is more annoying than anything, but it eventually goes away. I think it’s probably also safe to say that most people know that malaria is spread by mosquito bites. However, what’s less talked about are the different species of malaria and the need for different treatments depending on the type one has. The most deadly type of malaria is Plasmodium falciparum, and is most common in sub-Saharan Africa. However, another type—Plasmodium vivax (P. vivax)—tends to be the most difficult to cure. P. vivax malaria lives dormant in the liver and can relapse, causing malaria again anywhere between a few weeks and several months after the initial bite. It’s most prevalent in South and South East Asia, Latin America, and the horn of Africa and is responsible for 70-390 million cases of malaria per year. You may be asking yourself, “what’s the point of me telling you all this?” At the tail end of 2013, we heard the news that an investigational antimalarial drug—tafenoquine—for the treatment and radical cure of P. vivax had completed a Phase IIb study. Tafenoquine is being developed by GHTC member Medicines for Malaria Venture (MMV)—a nonprofit working to reduce the burden of malaria by discovering, developing, and facilitating the delivery of new and effective antimalarial drugs—and the pharmaceutical company GlaxoSmithKline (GSK). The results of the Phase IIb study were published in The Lancet last December.   The most deadly type of malaria is Plasmodium falciparum, and is most common in sub-Saharan Africa. However, another type—Plasmodium vivax (P. vivax)—tends to be the most difficult to cure. P. vivax malaria lives dormant in the liver and can relapse, causing malaria again anywhere between a few weeks and several months after the initial bite.

Under the designation, the FDA will work closely with the sponsors (GSK and MMV) to provide guidance to expedite the development of tafenoquine. If approved, tafenoquine offers the potential for a single dose option. However, tafenoquine still has to go through more clinical trials, and regulatory review and approval before patients are potentially able to receive treatment for P. vivax malaria. Regardless, both the completion of the Phase IIb clinical trial and it being designated FDA Breakthrough Therapy status are encouraging news that should be told. It’s true there has been much progress in fighting malaria over the years, but hundreds of thousands of people still die each year from P. falciparum and many more suffer the subtle, chronic effects of repeated infection with P. vivax so further research efforts to tackle malaria are still required. Global health research has created lifesaving health tools that have contributed to some of the most astounding public health successes—both domestically and abroad. Research such as that being taken on by MMV and other nonprofit product developers should be supported so that new and much-needed technologies can be developed and eventually accessed by those that need them most. Research in malaria is clearly needed to develop additional tools in the arsenal against a potentially deadly mosquito bite.
