In this regular feature on Breakthroughs, we highlight some of the most interesting reads in global health research from the past week. Results of a first-of-its-kind clinical trial of a new tuberculosis (TB) vaccine candidate show the candidate vaccine was safe and well tolerated. However, the candidate vaccine did not prevent TB disease when administered as a boost to the currently used BCG vaccine. The Bill & Melinda Gates Foundation has awarded the Task Force for Global Health a five-year, $28.8 million grant to establish a research support center for neglected tropical diseases. A new article examines the challenges and opportunities ahead for scientists developing vaccines against infectious diseases such as HIV, malaria, and TB. Scientists have demonstrated the ability to deliver a dried vaccine to the skin without a traditional needle. Researchers say that this technique would offer several benefits, including removing the need for refrigeration, providing a cheaper alternative to hypodermic needles, and reducing safety risks from needle contamination. A new study co-edited by the World Trade Organization, World Health Organization, and World Intellectual Property Organization outlines policies needed to advance new medical and health technologies, and to ensure that they reach the people who need them.

Going into December 2012, Congress had neither completed its work on the federal budget for fiscal year (FY) 2013 nor decided how to avoid sequestration—widespread and indiscriminate cuts to all federal programs. On January 1, just before sequestration was scheduled to take place, a deal was finally reached between the White House and Congress. However, instead of approving a long-term balanced solution, policymakers have transferred and delayed sequestration only temporarily. Below, we provide a summary of what the compromise means for the federal budget, and what might happen to global health and international development programs. Sequestration Just after the New Year, President Obama signed into law and Congress enacted the American Taxpayer Relief Act (ATRA). The legislation delays sequestration for over two months. It also reduces the level of the total cuts that would occur under sequestration from $109 billion to $85 billion. The new ‘fiscal cliff’ date is March 27, which is when the new FY2013 sequester is now scheduled to occur. Not coincidentally, that is the same day that the FY2012 continuing resolution, now funding the government, expires. And it will also be about a month after the United States will reach its debt ceiling. Negotiations on raising the debt ceiling will no doubt be tied to the debate over a long-term budget plan to avoid further sequestration cuts. For now, we don’t know exactly what the impact of the new sequestration would be on global health research and development programs. Assuming that all programs are cut proportionately, most global health and research programs would likely be cut by 5.9 percent in fiscal year 2013. The fiscal cliff deal instructs the Administration to release a report on sequestration on March 1, before the cuts occur. For now, we don’t know exactly what the impact of the new sequestration—which is looking more and more likely—would be on global health research and development (R&D) programs for FY2013. Assuming that all programs are cut proportionately, most global health and R&D programs would likely be cut by 5.9 percent in FY2013 (instead of the previous value of 8.2 percent). As an example, global health programs at the State Department and US Agency for International Development (USAID) would see an estimated cut of $482 million, and the overall National Institutes of Health (NIH) budget could be cut by an estimated $1.8 billion. During the discussions in March, it’s possible that Congress will make any number of decisions regarding the budget and sequestration—including constructing a long-term budget deal that nullifies sequestration, or delays it yet again. Given the lack of transparency around the budget negotiations, any attempt to quantify the impact on agencies and programs is just speculation at this point. FY2013 & FY2014 The difference between the old sequestration level and the new one is paid for through changes in retirement savings and tax laws, as well as a reduction in the federal budget caps for FY2013 and FY2014. FY2013’s budget cap is now $4 billion lower than it was two weeks ago. Therefore, if Congress creates a new spending package for the rest of FY2013 in March, a total of $4 billion will need to be cut from the total federal budget. This would translate to roughly a 0.4 percent cut across global health programs—if the cuts are distributed proportionately. However, Congress also has the option to extend the continuing resolution FY2013 through the rest of the fiscal year, which would result in cuts higher than 0.4 percent. During December 2012, congressional appropriations staff did agree on most of the FY2013 appropriations legislation. It appears that funding for global health programs at USAID fared well, and could be as high as $8.4 billion. This compares with USAID’s funding level of $8.167 billion for FY2012. However, until Congress debates these issues in March, we won’t know for sure if that agreed level will stick. For other global health and R&D programs at NIH, the Centers for Disease Control and Prevention (CDC), and the US Food and Drug Administration (FDA), it’s less clear whether there has been agreement in Congress. The legislation that funds NIH, FDA and CDC, for example, is always one of the most contentious budget debates in Congress. Adding one more wrench to the usual appropriations process going forward, the Obama Administration needs more time to prepare its budget request for FY2014. While normally we would expect this in early February, it is more likely that this will be at least a month late, which could result in a contracted appropriations season. The sweeping, indiscriminate cuts that sequestration—both old and new—would entail will ultimately damage progress in global health R&D. As the March debates over the federal budget begin, Congress should find a way to get the appropriations process back on track and commit to a balanced, thoughtful, long-term plan that protects smart, effective, life-saving investments in global health R&D and other humanitarian programs.

In this regular feature on Breakthroughs, we highlight some of the most interesting reads in global health research from the past week. The US Agency for International Development has released a report to Congress on its activities in global health research and development (R&D). The report also outlines the agency’s strategy for global health R&D from 2011 to 2015. While the Obama Administration is expected to continue including science and technology (S&T) in its diplomacy agenda, US diplomatic efforts in S&T may be more reliant on collaboration with the private sector due to expected government spending cuts. The Global Alliance to Prevent Prematurity and Stillbirth has released a new video, called “Born in Silence,” that sheds light on stillbirth worldwide. Approximately three million babies are stillborn each year worldwide. amfAR—the Foundation for AIDS Research—released updated estimates for the potential human impact of federal budget cuts to US global health programs. A candidate dengue vaccine developed by scientists at the National Institutes of Health has been found to be safe and effective in most vaccine recipients, according to results from an early-stage clinical trial. The World Health Organization Executive Board this week approved a draft resolution on neglected disease R&D financing and coordination. The resolution will be considered at the next World Health Assembly in May.

The New Year has brought some much-needed good news in the fight against tuberculosis (TB). The US Food and Drug Administration (FDA) recently announced that it has approved a new treatment for multidrug-resistant TB that can be used as an alternative when other drugs fail. The approval is the first time in 40 years that the FDA had approved a drug that attacks TB in a different way from currently available treatments. The new drug, bedaquiline, is made by Janssen Therapeutics. It will be sold under the brand name Sirturo, and is the first drug developed specifically to treat multi-drug resistant TB involving the lungs. Sirturo was approved under the FDA’s accelerated approval program, which allows the agency to approve a drug to treat a serious disease based on clinical data showing that the drug will likely benefit patients in need. According to the FDA, this program provides patients earlier access to promising new treatments while the drug developer conducts additional studies to confirm the drug’s benefits and safety.

A study in September in The Lancet found that almost 44 percent of patients with TB in countries like Russia, Peru, and Thailand showed resistance to at least one second-line drug. “Multidrug-resistant tuberculosis poses a serious health threat throughout the world, and Sirturo provides much-needed treatment for patients who have don’t have other therapeutic options available,” Edward Cox, director of the Office of Antimicrobial Products in the FDA’s Center for Drug Evaluation and Research, said. Given that the standard drugs used to treat the disease were developed in the 1950s and 1960s, it is no surprise that the TB bacterium has become more and more resistant to these older drugs over the past 50 years. There is a pressing and urgent need for even more new TB drugs, which makes this new FDA approval so significant. It is also noteworthy that the FDA approved Sirturo under its accelerated approval program, in addition to granting the drug fast track, priority review, and orphan-product status. Beyond the lifesaving benefits of the drug itself, these FDA programs resulted in quicker access to this much-needed new TB drug and should serve as models for other drugs desperately needed around the world. It’s critical that the FDA continues to support its priority review, fast track, and similar programs, which can help speed access to safe and effective global health drugs. It’s equally critical that Congress provides the FDA with sufficient funding to carry out this global health work. With the threat of sequestration—which would result in a cut of $318 million for the FDA—still looming, policymakers in Congress must prevent sequestration and protect FDA’s global health activities. Otherwise, approvals for new global health drugs like Sirturo could suffer. “There is no question that we need more and better treatments for drug-resistant TB. And we’ll continue to need new drugs as the disease mutates or changes,” FDA Commissioner Margaret Hamburg wrote in a blog post about the approval. “Meanwhile, Sirturo is a welcome addition to the drugs that we have available to treat patients who have multi-drug resistant TB who need this drug as part of their treatment regimen.”
