The Centers for Disease Control and Prevention has updated information about cases of e-cigarette, or vaping, product use–associated lung injury (EVALI): As of Nov. 12, there have been 2,172 cases reported from 49 states (all except Alaska), the District of Columbia, and two U.S. territories (Puerto Rico and U.S. Virgin Islands). Forty-two deaths have been confirmed in 24 states and the District of Columbia, the CDC reported.

Laboratory test results of bronchoalveolar lavage fluid samples from 29 patients submitted to CDC from 10 states found vitamin E acetate in all of the samples. This is the first time a chemical of concern has been found in biologic samples from patients with EVALI. These findings provide direct evidence of vitamin E acetate at the primary site of injury within the lungs.

Tetrahydrocannabinol (THC) was identified in 82% of the samples and nicotine was identified in 62% of the samples. Testing continues for other chemicals including plant oils, petroleum distillates like mineral oil, medium-chain triglycerides oil, and terpenes, which are compounds commonly found in or added to THC products. None of these chemicals has been detected in the bronchoalveolar lavage fluid samples tested.

CDC releases update of 2013 Antibiotic Resistance Threats Report

Article Type
Changed
Fri, 11/15/2019 - 12:46

“You and I are living in a time when some miracle drugs no longer perform miracles and families are being ripped apart by a microscopic enemy. The time for action is now and we can be part of the solution,” said Robert R. Redfield, MD, director of the Centers for Disease Control and Prevention in his foreword to the new CDC report on antibiotic resistance.

In this update of the previous 2013 report, the CDC details how antibiotic-resistant bacteria and fungi cause more than 2.8 million infections and 35,000 deaths in the United States each year. The current report uses EHRs and other data sources obtained by the CDC for relevant infections extrapolated to develop national disease incidence. The report focuses on “the top 18 pathogens that require attention now,” advises specific steps be taken to address these pathogens, and puts into perspective the future of antibiotic development, their use and abuse, and the continuing threat of antibiotic resistance.

The CDC categorizes these 18 pathogens as either an urgent, serious, or concerning threat.



Urgent Threats

  • Carbapenem-resistant Acinetobacter, which cause pneumonia and wound, bloodstream, and urinary tract infections; they tend to affect patients in ICUs. Of particular concern, some Acinetobacter are resistant to nearly all antibiotics, with few new drugs in development (8,500 hospital infections in 2017; 700 deaths).
  • Candida auris, a drug-resistant fungus that was first identified in 2009 in Asia and has quickly become a cause of severe infections around the world; it is extremely difficult to eradicate from health care settings. It began spreading in the United States in 2015, with 323 cases reported in 2018 (90% resistant to at least one antifungal, and 30% resistant to at least two antifungals).
  • Clostridioides difficile, which can cause life-threatening diarrhea, most often in people who have taken antibiotics for other conditions. It is the most common health care–associated infection, and although decreasing in the health care system, it has not decreased in community settings (223,900 hospital infections in 2017, and 12,800 estimated deaths).
  • Carbapenem-resistant Enterobacteriaceae, which most frequently infect patients who require devices such as catheters and those taking long courses of some antibiotics. Of particular concern is the fact that these bacteria contain a transmissible plasmid that can transfer their drug resistance to other pathogens (13,100 hospital infections in 2017, and 1,100 estimated deaths).
  • Drug-resistant Neisseria gonorrhoeae, which is a sexually transmitted disease that can result in life-threatening ectopic pregnancy, lead to infertility, and can increase the risk of getting and giving HIV; it can also cause cardiovascular and neurological problems. It is resistant to all but one class of antibiotics, and half of all infections are resistant to at least one antibiotic (550,000 drug-resistant infections yearly).

Serious Threats

  • Drug-resistant Campylobacter.
  • Drug-resistant Candida.
  • Extended spectrum beta-lactamase–producing Enterobacteriaceae.
  • Vancomycin-resistant Enterococci.
  • Multidrug-resistant Pseudomonas aeruginosa.
  • Drug-resistant nontyphoidal Salmonella.
  • Drug-resistant Salmonella serotype Typhi.
  • Drug-resistant Shigella.
  • Methicillin-resistant Staphylococcus aureus (MRSA).
  • Drug-resistant Streptococcus pneumoniae.
  • Drug-resistant Tuberculosis.



Concerning Threats

These comprise erythromycin-resistant group A Streptococcus and clindamycin-resistant group B Streptococcus.



In addition, the CDC has established a Watch List of three pathogens to be wary of: azole-resistant Aspergillus fumigatus, drug-resistant Mycoplasma genitalium, and drug-resistant Bordetella pertussis.

Because antibiotic resistance is a global phenomenon caused by and affecting everyone, the CDC provided solutions to the problem of antibiotic resistance at every level of society. This “comprehensive and coordinated response implements the U.S. National Action Plan for Combating Antibiotic-Resistant Bacteria” and includes cooperation with the Department of Health and Human Services, Department of Veterans Affairs, Department of Defense, Department of State, and Department of Agriculture, according to the report.

The key components of this response include using data and new technologies to detect and track antibiotic resistance; infection prevention and containment, especially in terms of outbreak response; improving antibiotic use across populations (one successful example being a 16% decrease of outpatient antibiotic prescribing to children during 2011-2017); improvements in the identification and intervention in the environment including water and soil and in sanitation; and a significant investment in vaccines, diagnostics, and novel therapeutics (the CDC provided nearly $110 million to 96 institutions for work in these areas).

The report also details some hope in the development of new antibiotics. As of June 2019, there were 42 new antibiotics in development, including 4 with new drug applications submitted, 17 with the potential to treat serious gram negative bacteria, and 11 that could address the urgent threats of gonorrhea or C. difficile. Overall, a quarter of these new antibiotics represent a novel drug class or use a novel mechanism of action.

Furthermore, 84% of U.S. hospitals report a stewardship program meeting all seven of CDC’s Core Elements of Hospital Antibiotic Stewardship. Proper stewardship is at the core of preventing the development of new antibiotic resistant pathogen strains.

In addition, the CDC noted a 5% overall decline in antibiotic prescribing in outpatient settings during 2011-2016.

“The problem will get worse if we do not act now, but we can make a difference,” according to Dr. Redfield. “Simply, here’s what works. Preventing infections protects everyone. Improving antibiotic use in people and animals slows the threat and helps preserve today’s drugs and those yet to come. Detecting threats and implementing interventions to keep germs from becoming widespread saves lives.”

In response to the release of the report, the AMA issued a supporting statement and cited its collection of educational resources for physicians focused on antibiotic use, resistance, and stewardship.

Similarly, the Society for Healthcare Epidemiology of America (SHEA) stated that hospitals were “a bright spot” in the CDC report and offered tools and resources available to educate and inform health care professionals about best practices in infection prevention and control, as well as antibiotic stewardship.

FDA still concerned about biotin affecting troponin tests

Article Type
Changed
Wed, 11/13/2019 - 14:21

The Food and Drug Administration has issued another safety communication warning that biotin can significantly interfere with laboratory tests for troponin.

However, not all troponin tests are affected, according to the update. “Since the FDA’s safety communication on this topic in 2017, some lab test developers have been successful at mitigating the biotin interference of their assays, but others have not yet addressed it,” according to the new communication, issued in early November.

Also known as vitamin B7 and appearing in many dietary supplements, including prenatal multivitamins and supplements for hair, skin, and nail growth, biotin can lead to falsely low results on some troponin tests, especially at high levels. The worry is that biotin interference could therefore lead to missed diagnoses. The FDA has provided a list of those tests that have not taken biotin’s effects into account, titled “Biotin Interference with Troponin Lab Tests – Assays Subject to Biotin Interference.”

The daily recommended allowance for biotin, according to the communication, is about 0.3 mg, but it isn’t always clear how much is actually included in supplements – some can contain 20 mg or even as much as 100 mg per pill of biotin. The communication includes recommendations for patients, health care professionals, laboratory personnel, and lab test manufacturers and developers.

The full safety communication can be found on the FDA website, and problems with tests can be reported via the FDA’s MedWatch Voluntary Reporting Form.

Fentanyl-related deaths show strong regional pattern

Article Type
Changed
Fri, 11/15/2019 - 14:25

 

Fentanyl was involved in more overdose deaths than any other drug in 2017, and the death rate in New England was 15 times higher than in regions of the Midwest and West, according to the National Center for Health Statistics.

Nationally, fentanyl was involved in 39% of all drug overdose deaths and had an age-adjusted death rate of 8.7/100,000 standard population in 2017. In 2016, when fentanyl also was the most involved drug in the United States, the corresponding figures were 29% and 5.9/100,000, the agency said in a recent report.

Fentanyl was the most involved drug in overdose deaths for 6 of the country’s 10 public health regions in 2017, with a clear pattern of decreasing use from east to west. The highest death rate (22.5/100,000) occurred in Region 1 (New England) and the lowest rates (1.5/100,000) came in Region 6 (Arkansas, Louisiana, New Mexico, Oklahoma, and Texas) and Region 9 (Arizona, California, Hawaii, and Nevada), the researchers said.

A somewhat similar pattern was seen for heroin, which was second nationally on the list of drugs most frequently involved in overdose deaths (23%), except that New England was somewhat below three other regions in the East and upper Midwest. The highest heroin death rate (8.6/100,000) was seen in Region 2 (New Jersey and New York) and the lowest (2.2) occurred in Region 9, they said, based on data from the National Vital Statistics System’s mortality files.

The fentanyl pattern was even more closely repeated with cocaine, third in involvement nationally at 21% of overdose deaths in 2017. The high in overdose deaths (9.5/100,000) came in Region 1 again, and the low in Region 9 (1.3), along with Region 7 (Iowa, Kansas, Missouri, and Nebraska) and Region 10 (Alaska, Idaho, Oregon, and Washington), the report showed.

The regional pattern of overdose deaths for methamphetamine, which was fourth nationally in involvement (13.3%), basically reversed the other three drugs: highest in the West and lowest in the Northeast. Region 9 had the highest death rate (5.2/100,000) and Region 2 the lowest (0.4), with Region 1 just ahead at 0.6.

“Understanding these regional differences in the drugs most frequently involved in drug overdose deaths may help inform prevention and policy efforts,” the investigators wrote.

Fentanyl was the most involved drug in overdose deaths for 6 of the country’s 10 public health regions in 2017, with a clear pattern of decreasing use from east to west. The highest death rate (22.5/100,000) occurred in Region 1 (New England) and the lowest rates (1.5/100,000) came in Region 6 (Arkansas, Louisiana, New Mexico, Oklahoma, and Texas) and Region 9 (Arizona, California, Hawaii, and Nevada), the researchers said.

A somewhat similar pattern was seen for heroin, which was second nationally on the list of drugs most frequently involved in overdose deaths (23%), except that New England was somewhat below three other regions in the East and upper Midwest. The highest heroin death rate (8.6/100,000) was seen in Region 2 (New Jersey and New York) and the lowest (2.2) occurred in Region 9, they said, based on data from the National Vital Statistics System’s mortality files.

The fentanyl pattern was even more closely repeated with cocaine, third in involvement nationally at 21% of overdose deaths in 2017. The high in overdose deaths (9.5/100,000) came in Region 1 again, and the low in Region 9 (1.3), along with Region 7 (Iowa, Kansas, Missouri, and Nebraska) and Region 10 (Alaska, Idaho, Oregon, and Washington), the report showed.

The regional pattern of overdose deaths for methamphetamine, which was fourth nationally in involvement (13.3%), basically reversed the other three drugs: highest in the West and lowest in the Northeast. Region 9 had the highest death rate (5.2/100,000) and Region 2 the lowest (0.4), with Region 1 just ahead at 0.6.

“Understanding these regional differences in the drugs most frequently involved in drug overdose deaths may help inform prevention and policy efforts,” the investigators wrote.

CDC identifies probable culprit in vaping lung injuries

Tue, 11/12/2019 - 11:33

 

The Centers for Disease Control and Prevention has announced a possible breakthrough in the hunt for the source of a nationwide outbreak of e-cigarette, or vaping, product use–associated lung injuries (EVALI): vitamin E acetate found in lung fluid of victims.

In a telebriefing on Friday, Anne Schuchat, MD, the CDC’s principal deputy director, provided an update on recent lab findings and on case and death numbers reported so far to the CDC. The findings and more case information were published in the Mortality and Morbidity Weekly Report.

At the telebriefing, Dr. Schuchat stated that CDC has received 29 samples of bronchoalveolar lavage (BAL) fluid from EVALI patients from 10 states and that vitamin E acetate was identified in all samples. Vitamin E acetate has already been found in some vaping devices and the discovery of the chemical in the lungs of patients increases the likelihood that this toxin is at least one source of EVALI. These findings are the first to link substances found in vaping products with biological samples from patients hospitalized with EVALI.

Tetrahydrocannabinol (THC) was found in 23 of 28 samples tested and nicotine was found in 16 of 26 samples tested. Other diluents and additives of concern (such as plant oils, medium chain triglyceride oil, petroleum distillates, and diluent terpenes) were not detected in BAL fluid specimens from EVALI patients.

BAL fluid specimens were collected from hospitalized EVALI patients in the course of their treatment, although not for the specific purpose of the CDC investigation, and sent to the CDC by public health laboratories and health departments in California, Connecticut, Hawaii, Illinois, Maryland, Michigan, Minnesota, Texas, Utah, and Wisconsin for analysis.

Dr. Schuchat stated that, as of Nov. 5, there have been 2,051 cases of EVALI reported to the CDC and 39 EVALI patients have died, with other deaths still under investigation as possibly related to EVALI. She said that the trend in new EVALI cases reported appears to be decreasing, but some states continue to see new cases. She cautioned that the lab findings of vitamin E acetate in BAL fluid do not rule out other possible compounds or ingredients that may contribute to EVALI and said the investigation will continue.
 

E-cigarette user survey

During the telebriefing, Jennifer Layden, MD, PhD, chief medical officer and state epidemiologist with the Illinois Department of Public Health (IDPH), gave an update on her department’s efforts to investigate vaping behaviors that might have led to EVALI in e-cigarette users and also to obtain more information on sources of vaping devices that could be linked to EVALI. The data were also reported in a MMWR.

The IDPH conducted an online public survey during September 2019 to October 2019 targeting e-cigarette, or vaping, product users in Illinois. The survey was promoted via social media on the IDPH website, local health departments, and other outlets. The survey yielded 4,631 respondents who answered questions about the frequency of vaping, sources of supply, and types of substances used. The investigators were then able to compare vaping-use habits and behaviors with similar information gleaned from EVALI patients.

Among survey respondents, 94% reported using any nicotine-containing e-cigarette, or vaping, products in the past 3 months; 21% used any THC-containing products; and 11% used both THC-containing products and nicotine-containing products. THC-containing product use was highest among survey respondents aged 18-24 years (36%) and decreased with increasing age. Compared with these survey respondents, EVALI patients were more likely to report exclusive use of THC-containing products (adjusted odds ratio, 2.0; 95% confidence interval, 1.1-3.6), frequent use (more than five times per day) of these products (aOR, 3.1; 95% CI, 1.6-6.0), and obtaining these products from informal sources, such as from a dealer, off the street, or from a friend (aOR, 9.2; 95% CI, 2.2-39.4). In addition, “the odds of using Dank Vapes, a class of largely counterfeit THC-containing products, was also higher among EVALI patients” (aOR, 8.5; 95% CI, 3.8-19.0), according to the MMWR.
 

 

 

Recommendations

CDC recommends that people should not buy any type of e-cigarette, or vaping, products, particularly those containing THC, off the street. They should also refrain from modifying or adding any substances to e-cigarette, or vaping, products that are not intended by the manufacturer, including products purchased through retail establishments.

Dr. Layden concluded, “we are in a better place today than we were a few weeks ago in terms of having one very strong culprit of concern based on the lung fluid testing,” but since the specific substances causing lung injury are not yet known, the only way to assure that individuals are not at risk while the investigation continues is to consider refraining from use of all vaping products.

Luspatercept-aamt (Reblozyl) is an erythroid maturation agent that reduced the transfusion burden for patients with beta thalassemia in the BELIEVE trial of 336 patients. In total, 21% of patients who received luspatercept-aamt achieved at least a 33% reduction in red blood cell transfusions, compared with 4.5% of patients who received placebo, according to the FDA.

Common side effects associated with luspatercept-aamt were headache, bone pain, arthralgia, fatigue, cough, abdominal pain, diarrhea, and dizziness. Patients taking the agent should be monitored for thrombosis, the FDA advised.



Celgene, which makes luspatercept-aamt, said the agent would be available about 1 week following the FDA approval.

The FDA is also evaluating luspatercept-aamt as an anemia treatment in adults with very-low– to intermediate-risk myelodysplastic syndromes who have ring sideroblasts and require red blood cell transfusions. The agency is expected to take action on that application in April 2020.

Lung cancer on the decline, but still higher among men than women

Article Type
Changed
Fri, 11/08/2019 - 14:43

While lung cancer is generally on the decline among both sexes, men have a ways to go to catch up with women, according to the Centers for Disease Control and Prevention.

From 2007 to 2016, rates dropped among both sexes in metropolitan and nonmetropolitan areas, according to Mary Elizabeth O’Neil, MPH, and colleagues. Their report is in Morbidity and Mortality Weekly Report (MMWR Morb Mortal Wkly Rep. 2019 Nov 8;68[44];993-8). But lung cancer incidence in 2016 was still 40% higher among men than among women, said Ms. O’Neil, an epidemiologist at the CDC.

Rather than narrowly focusing on the “just stop smoking” message, “a comprehensive approach to lung cancer prevention and control includes such population-based strategies as screening for tobacco dependence, promoting tobacco cessation, implementing comprehensive smoke-free laws, testing all homes for radon and using proven methods to lower high radon levels, and reducing exposure to lung carcinogens such as asbestos.” According to the authors of the report, “increasing the implementation of these strategies, particularly among persons living in nonmetropolitan counties, might help to reduce disparities in the decline of lung cancer incidence.”

The recommendation is based on data extracted from the U.S. Cancer Statistics Database for 2007-2016. The data cover 97% of the population.

In nonmetropolitan counties in 2007, incidence rates among men were 60% higher (99 vs. 61 per 100,000). Although rates decreased in both sexes, they were still elevated compared with women in 2016 (82 vs. 58 per 100,000; 40%).

Over the 10-year period, the rate declined more among men than among women (–2.9% vs. –1.5%) in metropolitan areas. The pattern repeated in nonmetropolitan areas (–2.1% and –0.5%, respectively).

There were different declines in different age groups by region, the authors noted.

Men aged 45-54 years in metropolitan areas experienced the largest decline (–5.2%).

Among women, the largest decline occurred in metropolitan areas among those aged 35-44 years (–5%). In nonmetropolitan areas, women in this age group experienced a 3.6% decline and women aged 65-74 years, a 1.3% decline.

Among persons aged 35-54 years, incidence rates in nonmetropolitan and metropolitan counties did not differ by sex but were higher in nonmetropolitan counties than in metropolitan counties.

There were also overall changes in smoking patterns. According to 2017 data from the National Health Interview Survey data, more adults in metropolitan areas than nonmetropolitan areas smoked (23% versus 13%) but fewer had tried to quit (50% vs. 56%). Successful quitting attempts also were lower (5% vs. 9%).

Although it is a large contributing factor, smoking is not the only risk factor for lung cancer, the authors wrote. About 10%-15% of lung cancer patients have never smoked tobacco. Nonsmoked tobacco products and second-hand exposure to cigarette smoke are risks, as are indoor radon and asbestos exposure.

Clinicians can help improve this scenario by screening at each office visit, the authors said. The recommendation is based on U.S. Preventive Services Task Force guidance.

“Lung cancer screening is recommended for adults at high risk for developing lung cancer because of their age and cigarette smoking history. Screening efforts can identify lung cancer in its early stages and provide an important opportunity to promote tobacco smoking cessation.”

However, lack of insurance among residents of nonmetropolitan areas may hamper access to these services, they said. In those regions, “a higher percentage of residents aged less than 65 years report being uninsured compared with those in metropolitan areas.”

More than 60,000 cancer patients are hospitalized in the United States each year with evidence of neutropenia, resulting in more than 4,000 deaths, according to Ziextenzo maker Sandoz, a Novartis division.

The FDA approval was based on analytical, preclinical, and clinical research, including data from a three-way pharmacokinetics and pharmacodynamics study that compared pegfilgrastim-bmez with the reference drug pegfilgrastim (Neulasta) from the United States and the European Union. Pharmacokinetic and pharmacodynamic similarity were shown between pegfilgrastim-bmez with the reference drugs, and there were no clinically significant differences in safety or immunogenicity.



The most common adverse events associated with pegfilgrastim-bmez are bone pain and pain in the extremities, according to the label.

Wed, 05/06/2020 - 12:37

 

Stephen M. Hahn, MD, a radiation oncologist and researcher, may soon take the reins of the Food and Drug Administration.

Dr. Stephen Hahn

President Trump indicated his intent to nominate Dr. Hahn as FDA Commissioner in a brief Nov.1 statement that outlined Dr. Hahn’s background. Dr. Hahn currently serves as chief medical executive at MD Anderson Cancer Center, Houston, where he heads the radiology oncology division.

Dr. Hahn specializes in treating lung cancer and sarcoma and has authored 220 peer-reviewed original research articles, according to his biography. He was previously chair of the department of radiology oncology at the University of Pennsylvania, Philadelphia, and also served as a senior investigator at the National Cancer Institute.

Dr. Hahn completed his residency in radiation oncology at NCI and his residency in internal medicine at the University of California, San Francisco.

Margaret Foti, PhD, chief executive officer for the American Association for Cancer Research called Dr. Hahn a renowned expert in radiation oncology and research, an experienced and highly effective administrator, and an innovative leader.

“I have seen firsthand Dr. Hahn’s extraordinary dedication and commitment to cancer patients, and the AACR is extremely confident that he will be an outstanding leader for the FDA,” Dr. Foti said in a statement. “Dr. Hahn, who is board certified in both radiation and medical oncology, is esteemed for the breadth and depth of his scientific knowledge and expertise, and he has consistently advocated for a drug review process at the FDA that is both science-directed and patient-focused.”

The American Society of Clinical Oncology also congratulated Dr. Hahn on the upcoming nomination, noting that he has a strong grasp of the drug development process and understands the realities of working in a complex clinical care environment.

“The role of FDA commissioner requires a strong commitment to advancing the agency’s mission to protect public health across the United States, and an understanding of how to help speed innovations to get new treatments to patients, while also ensuring the safety and efficacy of the medical products that millions of Americans rely on to manage, treat, and cure their cancer,” the society stated. “ASCO has a long and productive history of collaborating with FDA, including with current acting Commissioner Norman E. “Ned” Sharpless, MD, in support of the agency’s important role in reducing cancer incidence, advancing treatment options, and improving the lives of individuals with cancer. We look forward to continuing our close collaboration to make it possible for every American with cancer to have access to medical products that are safe and effective.”

Dr. Sharpless will return to his position as NCI director; he served as interim FDA commissioner from the April departure of then-FDA commissioner, Scott Gottlieb, MD.

“As one of the nation’s leading oncologists who has devoted his entire professional career to helping patients in the fight against cancer, Ned is returning home to NCI to continue this work and we look forward to working closely with him once again,” Francis S. Collins, MD, director of the National Institutes of Health, said in a statement. “I want to thank Dr. Doug Lowy, principal deputy director of NCI, for having stepped in, once again, to take the helm at NCI and lead the institute so skillfully while Ned was at FDA.”

At press time, neither Dr. Hahn nor MD Anderson Cancer Center had returned messages seeking comment about his nomination.

Triple-drug therapy proves effective in CF patients with most common mutation

The dream of targeted therapies for cystic fibrosis may now be reality

Reinforcing previous findings, a new study has determined that the next-generation corrector elexacaftor, in combination with tezacaftor and ivacaftor, can effectively treat patients with Phe508del-minimal function genotypes who did not respond to previous cystic fibrosis transmembrane conductance regulator (CFTR) modulator regimens.

“These results provide evidence that elexacaftor-tezacaftor-ivacaftor can modulate a single Phe508del allele in people with cystic fibrosis, thus addressing the underlying cause of disease in the large majority of patients,” wrote Peter G. Middleton, PhD, of the University of Sydney (Australia) and his coauthors. The study was published in the New England Journal of Medicine.

To further determine if the elexacaftor-tezacaftor-ivacaftor regimen was effective and safe, the researchers launched a randomized, placebo-controlled phase 3 trial of 403 cystic fibrosis patients age 12 or older who had a single Phe508del allele. Patients in the combination group (n = 200) received 200 mg of elexacaftor once daily, 100 mg of tezacaftor once daily, and 150 mg of ivacaftor every 12 hours for 24 weeks. Patients in the other group (n = 203) received matched placebos.

At 14 weeks, patients in the combination group had a change in percentage of predicted forced expiratory volume in 1 second (FEV1) that was 13.8 points higher than the placebo group (95% confidence interval, 12.1-15.4, P less than .001). At 24 weeks, the combination group had a predicted FEV1 difference that was 14.3 percentage points higher (95% confidence interval, 12.7-15.8, P less than .001). The rate of pulmonary exacerbations was 63% lower (rate ratio 0.37; 95% CI, 0.25-0.55, P less than .001) and sweat chloride concentration was 41.8 mmol/L lower (95% CI, –44.4 to –39.3, P less than .001) in the combination group through 24 weeks.

At least one adverse event occurred in 93.1% of patients in the combination group and 96% of patients in the placebo group. Serious adverse events occurred in 28 patients (13.9%) in the combination group and 42 patients (20.9%) in the placebo group. There were no deaths in either group.

The study was funded by Vertex Pharmaceuticals. The authors had disclosures, including receiving personal fees and grants from various pharmaceutical companies and being on the advisory board, owning stock, or being an employee of Vertex Pharmaceuticals.

After 30 years, new research from Middleton et al. and others appears to be the breakthrough we’ve been waiting for in treating cystic fibrosis, wrote Francis S. Collins, MD, PhD, of the National Institutes of Health in an accompanying editorial (N Engl J Med. 2019 Oct 31. doi: 10.1056/NEJMe1911602).

As one of the researchers who discovered the cystic fibrosis gene, he acknowledged the 3 decades of work that followed their discovery and the excitement that comes from being able to counter the common Phe508del CFTR mutation that afflicts so many cystic fibrosis patients. “These findings indicate that it may soon be possible to offer safe and effective molecularly targeted therapies to 90% of persons with cystic fibrosis,” he wrote.

“Yet we must not abandon the patients with cystic fibrosis who have null mutations and will not have a response to these drugs,” he added, noting that those challenges remain “substantial” and potentially will involve in vivo somatic-cell gene editing of airway epithelial cells. That said, what once was a dream 30 years ago now appears to be a reality.
 

Dr. Collins reported being a coinventor of the original patents on the CFTR gene, for which he donated all royalties to the Cystic Fibrosis Foundation.
