Benefits of BGF triple fixed-dose therapy consistent in COPD patients without exacerbation history
NEW ORLEANS – When looking specifically at the subgroup patients with no recent exacerbations, in patients with moderate to very severe chronic obstructive pulmonary disorder (COPD), an analysis of the phase 3 KRONOS study shows.
For that subgroup of patients with no moderate to severe exacerbations in the past year, BGF MDI was associated with a nominally significant reduction in the rate of subsequent COPD exacerbations, compared with glycopyrrolate/formoterol fumarate (GFF) MDI, according to investigator Fernando J. Martinez MD, of Weill Cornell Medical College, New York.
Results for the COPD patients with no recent history of exacerbation were consistent with the overall results of KRONOS, suggesting that the benefits of BGF MDI shown in that study were not driven by patients with a recent exacerbation history, Dr. Martinez said at the annual meeting of the American College of Chest Physicians.
“It was clear that the effect of this particular triple did not really appear to be dramatically different by the prior history or not in the comparison of the triple versus dual bronchodilator,” he said in a late-breaking clinical trial session.
About three-quarters of the patients in KRONOS (1,411 out of 1,896) lacked a recent exacerbation history. These patients had a mean age of 65.5 years, 72.8% were male, and 69.9% used inhaled corticosteroids at screening, which are demographics were similar to the overall KRONOS patient population, Dr. Martinez said.
In this subset of patients with no recent exacerbation history, treatment with BGF MDI significantly reduced the rate of moderate or severe exacerbations, compared with GFF MDI, with a treatment incidence rate ratio of 0.52 (95% confidence interval, 0.37-0.72; P = .0001).
“The results were remarkably similar,” Dr. Martinez said. “I was surprised, to be honest with you, when I saw these results. I did not anticipate that would be the case.”
By contrast, BGF MDI did not significantly reduce the rate of moderate or severe exacerbations, compared with budesonide/formoterol fumarate (BFF) MDI or open-label budesonide/formoterol fumarate dihydrate dry-powder inhaler (BUD/FORM DPI) as studied in KRONOS, Dr. Martinez said.
The change from baseline in morning predose trough forced expiratory volume in 1 second (FEV1) at week 24 was significantly improved for BGF MDI, compared with BFF MDI and BUD/FORM DPI, but not compared with GFF MDI, according to the investigator. Similarly, the FEV1 area under the curve from 0 to 4 hours was significantly improved for BGF MDI, compared with BFF MDI and BUD/FORM DPI, but not compared with GFF MDI.
Dr. Martinez reported disclosures related to AstraZeneca, GlaxoSmithKline, Boehringer Ingelheim, Chiesi, Sunovion, and Teva.

Smokers with PE have higher rate of hospital readmission
NEW ORLEANS – , according to a retrospective study.
The rate of readmission was significantly higher among patients with tobacco dependence, and tobacco dependence was independently associated with an increased risk of readmission.
“This is the first study to quantify the increased rate of hospital readmission due to smoking,” said study investigator Kam Sing Ho, MD, of Mount Sinai St. Luke’s and Mount Sinai West, New York.
Dr. Ho and colleagues described this study and its results in a poster presented at the annual meeting of the American College of Chest Physicians.
The researchers analyzed data on 168,891 hospital admissions of adults with PE, 34.2% of whom had tobacco dependence. Patients with and without tobacco dependence were propensity matched for baseline characteristics (n = 24,262 in each group).
The 30-day readmission rate was significantly higher in patients with tobacco dependence than in those without it – 11.0% and 8.9%, respectively (P less than .001). The most common reason for readmission in both groups was PE.
Dr. Ho said the higher readmission rate among patients with tobacco dependence might be explained by the fact that smokers have a higher level of fibrinogen, which may affect blood viscosity and contribute to thrombus formation (Proc Am Thorac Soc. 2005;2[1]:71-7).
The investigators also found that tobacco dependence was an independent predictor of readmission (hazard ratio, 1.43; P less than .001). And the mortality rate was significantly higher after readmission than after index admission – 6.27% and 3.15%, respectively (P less than .001).
The increased risk of readmission and death among smokers highlights the importance of smoking cessation services. Dr. Ho cited previous research suggesting these services are underused in the hospital setting (BMJ Qual Improv Rep. 2014;3[1]:u204964.w2110).
“Given that smoking is a common phenomenon among patients admitted with pulmonary embolism, we suggest that more rigorous smoking cessation services are implemented prior to discharge for all active smokers,” Dr. Ho said. “[P]atients have the right to be informed on the benefits of smoking cessation and the autonomy to choose. Future research will focus on implementing inpatient smoking cessation at our hospital and its effect on local readmission rate, health resources utilization, and mortality.”
Dr. Ho has no relevant relationships to disclose.

Tiotropium/olodaterol improved lung function in steroid-free patients with COPD
New Orleans – compared with tiotropium alone, according to results of a pooled analysis of phase 3 trial data.
Lung function, symptoms, and quality of life were all improved irrespective of disease severity and baseline symptoms, and these benefits were apparent across multiple subgroups of non-ICS patients, investigator Peter M. Calverley, MBChB, of the University of Liverpool (England) reported at the annual meeting of the American College of Chest Physicians.
“Perhaps frustratingly, we can’t personalize [treatment] – everybody seemed to get benefit across the board, and the magnitude of that benefit was rather similar,” Dr. Calverley said in a podium presentation of the results.
The subgroup analysis was undertaken to fill a knowledge gap, according to Dr. Calverley, regarding the efficacy of combined long-acting muscarinic antagonist/long-acting beta2-agonist (LAMA/LABA) treatment in the sizable proportion of COPD patients who are not receiving ICS.
Patients in LAMA/LABA clinical trials are frequently taking multiple therapies, including ICS, he explained.
The post hoc analysis of pooled data from the TONADO 1 and 2 and OTEMTO 1 and 2 trials included a total of 1,596 patients with COPD who were not receiving ICS at trial enrollment.
The no-ICS patients receiving tiotropium/olodaterol had a significantly greater improvement in trough forced expiratory volume in 1 second (FEV1) response by week 12 of treatment, compared with patients receiving tiotropium alone (0.054 L; P less than .0001), the researcher reported.
The trough FEV1 improvement accruing to the tiotropium/olodaterol–treated patients was consistent across subgroups stratified according to GOLD stage and symptoms at baseline (such as Baseline Dyspnea Index), he added.
Transition Dyspnea Index (TDI) score at 12 weeks in these patients not receiving ICS was likewise superior in the tiotropium/olodaterol treated patients, compared with the tiotropium monotherapy group (.575; P less than .0001), while changes in St. George’s Respiratory Questionnaire (SGRQ) total scores also favored the combination treatment, according to the analyses presented.
Taken together, results of this post hoc analysis support the use of dual bronchodilator therapy to improve key COPD outcomes, compared with single bronchodilator therapy. In addition, this strategy should be considered as an earlier treatment option, according to Dr. Calverley.
“Clearly dual bronchodilator therapy improves the key outcomes, compared with an effective single bronchodilator, and this perhaps is why it’s being picked up as an earlier treatment option, and certainly in some guidelines like the current [National Institute for Health Care and Excellence] guidelines where I live in the U.K., it’s becoming standard of care for most people with COPD,” he said in his presentation.
Dr. Calverley reported grants and personal fees from GlaxoSmithKline; personal fees from AstraZeneca, Recipharm, and Zambon; and personal and other fees from Boehringer Ingelheim outside the submitted work.

Dupilumab effective in early- and late-onset asthma
NEW ORLEANS – A new analysis suggests
Dupilumab may be more effective in reducing severe asthma exacerbations in patients with late-onset asthma, but the drug’s effect on lung function appeared the same regardless of asthma onset. Nicola Hanania, MD, of Baylor College of Medicine in Houston presented these results at the annual meeting of the American College of Chest Physicians.
Dr. Hanania and colleagues conducted a subanalysis of the LIBERTY ASTHMA QUEST study (NCT02414854). Previous data from this study showed that patients with uncontrolled, moderate to severe asthma who received dupilumab had fewer exacerbations and better lung function than did patients who received placebo (N Engl J Med. 2018;378:2486-96).
In their subanalysis, Dr. Hanania and his colleagues evaluated the efficacy of dupilumab, given at 200 mg or 300 mg every 2 weeks, in patients with early-onset asthma (at 40 years of age or younger) and late-onset asthma (at 41 years or older). The analysis included 919 patients with early-onset asthma who received dupilumab and 450 early-onset patients who received placebo. There were 345 patients with late-onset asthma who received dupilumab and 188 late-onset patients who received placebo.
Exacerbations
Dupilumab significantly reduced the adjusted annualized severe exacerbation rates during the 52-week treatment period. Significant reductions occurred in both early- and late-onset patients, though reductions were greater in the late-onset group.
In early-onset patients, dupilumab reduced severe exacerbations by 38% when given at 200 mg and by 37% when given at 300 mg (P less than .001 vs. placebo). In late-onset patients, dupilumab reduced exacerbations by 64% and 69%, respectively (P less than .001 vs. placebo).
Dr. Hanania said it isn’t clear why late-onset patients appear to derive more benefit with regard to exacerbations. It may be because these patients have more comorbidities or because they aren’t using their inhalers correctly. The researchers are investigating these possibilities.
Dr. Hanania went on to note that reductions in exacerbation rates were greatest in patients with elevated blood eosinophils (150 cells/mcL or greater) or fractional exhaled nitric oxide (FeNO; 25 ppb or greater).
In patients with early-onset asthma and elevated eosinophils, dupilumab reduced severe exacerbations by 50% when given at 200 mg and by 55% when given at 300 mg (P less than .001 vs. placebo). In late-onset patients with elevated eosinophils, dupilumab reduced exacerbations by 65% and 73%, respectively (P less than .001 vs. placebo).
In patients with early-onset asthma and elevated FeNO, dupilumab reduced severe exacerbations by 56% when given at 200 mg and by 52% when given at 300 mg (P less than .001 vs. placebo). In late-onset patients with elevated FeNO, dupilumab reduced exacerbations by 79% and 71%, respectively (P less than .001 vs. placebo).
Lung function
Dupilumab also improved prebronchodilator forced expiratory volume in 1 second (pre-BD FEV1), compared with placebo, with similar results in early- and late-onset patients.
In early-onset patients, the P values were less than .001 for both doses of dupilumab at weeks 12 and 52. In late-onset patients, the P values were less than .001 for the 300-mg dose at week 12 and the 200-mg dose at week 52, less than .01 for the 200-mg dose at week 12, and less than .05 for the 300-mg dose at week 52.
The effects of dupilumab on pre-BD FEV1 were greatest in patients with elevated eosinophils or FeNO. At week 12, the P value was less than .001 for both doses of dupilumab in early-onset patients with elevated eosinophils or FeNO. The P value was less than .01 for both doses in late-onset patients with elevated eosinophils. And the P value was less than .001 for both doses in late-onset patients with elevated FeNO.
This research was sponsored by Sanofi and Regeneron. Dr. Hanania disclosed relationships with Genentech, Novartis, AstraZeneca, Boehringer Ingelheim, GSK, Regeneron, and Sanofi.

In late-onset patients, the P values were less than .001 for the 300-mg dose at week 12 and the 200-mg dose at week 52, less than .01 for the 200-mg dose at week 12, and less than .05 for the 300-mg dose at week 52.
The effects of dupilumab on pre-BD FEV1 were greatest in patients with elevated eosinophils or FeNO. At week 12, the P value was less than .001 for both doses of dupilumab in early-onset patients with elevated eosinophils or FeNO. The P value was less than .01 for both doses in late-onset patients with elevated eosinophils. And the P value was less than .001 for both doses in late-onset patients with elevated FeNO.

NEW ORLEANS – A new analysis suggests
Dupilumab may be more effective in reducing severe asthma exacerbations in patients with late-onset asthma, but the drug’s effect on lung function appeared the same regardless of asthma onset. Nicola Hanania, MD, of Baylor College of Medicine in Houston presented these results at the annual meeting of the American College of Chest Physicians.
Dr. Hanania and colleagues conducted a subanalysis of the LIBERTY ASTHMA QUEST study (NCT02414854). Previous data from this study showed that patients with uncontrolled, moderate to severe asthma who received dupilumab had fewer exacerbations and better lung function than did patients who received placebo (N Engl J Med. 2018;378:2486-96).
In their subanalysis, Dr. Hanania and his colleagues evaluated the efficacy of dupilumab, given at 200 mg or 300 mg every 2 weeks, in patients with early-onset asthma (at 40 years of age or younger) and late-onset asthma (at 41 years or older). The analysis included 919 patients with early-onset asthma who received dupilumab and 450 early-onset patients who received placebo. There were 345 patients with late-onset asthma who received dupilumab and 188 late-onset patients who received placebo.
Exacerbations
Dupilumab significantly reduced the adjusted annualized severe exacerbation rates during the 52-week treatment period. Significant reductions occurred in both early- and late-onset patients, though reductions were greater in the late-onset group.
In early-onset patients, dupilumab reduced severe exacerbations by 38% when given at 200 mg and by 37% when given at 300 mg (P less than .001 vs. placebo). In late-onset patients, dupilumab reduced exacerbations by 64% and 69%, respectively (P less than .001 vs. placebo).
Dr. Hanania said it isn’t clear why late-onset patients appear to derive more benefit with regard to exacerbations. It may be because these patients have more comorbidities or because they aren’t using their inhalers correctly. The researchers are investigating these possibilities.
Dr. Hanania went on to note that reductions in exacerbation rates were greatest in patients with elevated blood eosinophils (150 cells/mcL or greater) or fractional exhaled nitric oxide (FeNO; 25 ppb or greater).
In patients with early-onset asthma and elevated eosinophils, dupilumab reduced severe exacerbations by 50% when given at 200 mg and by 55% when given at 300 mg (P less than .001 vs. placebo). In late-onset patients with elevated eosinophils, dupilumab reduced exacerbations by 65% and 73%, respectively (P less than .001 vs. placebo).
In patients with early-onset asthma and elevated FeNO, dupilumab reduced severe exacerbations by 56% when given at 200 mg and by 52% when given at 300 mg (P less than .001 vs. placebo). In late-onset patients with elevated FeNO, dupilumab reduced exacerbations by 79% and 71%, respectively (P less than .001 vs. placebo).
Lung function
Dupilumab also improved prebronchodilator forced expiratory volume in 1 second (pre-BD FEV1), compared with placebo, with similar results in early- and late-onset patients.
In early-onset patients, the P values were less than .001 for both doses of dupilumab at weeks 12 and 52. In late-onset patients, the P values were less than .001 for the 300-mg dose at week 12 and the 200-mg dose at week 52, less than .01 for the 200-mg dose at week 12, and less than .05 for the 300-mg dose at week 52.
The effects of dupilumab on pre-BD FEV1 were greatest in patients with elevated eosinophils or FeNO.

Robotic bronchoscopy beat standard techniques for targeting lung nodules
NEW ORLEANS –
A prospective study in a cadaver model showed that robotic bronchoscopy targeted nodules more effectively than electromagnetic navigation or an ultrathin bronchoscope with radial endobronchial ultrasound (UTB-rEBUS).
“This is really the first study to randomize, blind, and compare procedural outcomes between existing technologies in advanced bronchoscopy,” said Lonny Yarmus, DO, of Johns Hopkins Medicine in Baltimore.
Dr. Yarmus described this study, PRECISION-1, at the annual meeting of the American Society of Chest Physicians. The study was designed to compare the following:
- UTB-rEBUS (3.0 mm outer diameter and 1.7 mm working channel).
- Electromagnetic navigation bronchoscopy (Superdimension version 7.1).
- Robotic bronchoscopy (3.5 mm outer diameter and 2.0-mm working channel).
With all methods, a 21-gauge needle was used. For each nodule, UTB-rEBUS was done first to eliminate potential localization bias. The subsequent order of electromagnetic navigation and robotic bronchoscopy was determined based on block randomization.
Eight bronchoscopists performed a total of 60 procedures using each of the methods to target 20 nodules implanted in cadavers. The nodules were distributed across all lobes, 80% were in the outer third of the lung, and 50% had a positive bronchus sign on computed tomography (CT). The mean nodule size was 16.5 plus or minus 1.5 mm.
The study’s primary endpoint was the ability to localize and puncture target nodules within a maximum of three attempts per method. This includes center, peripheral, and distal punctures of nodules. Cone-beam CT was used to confirm that needles punctured the target lesions. The bronchoscopists were blinded to cone-beam CT results, and a blinded, independent investigator assessed whether nodule punctures were successful. The primary endpoint was met in 25% of UTB-rEBUS procedures, 45% of electromagnetic navigation procedures, and 80% of robotic bronchoscopy procedures.
The study’s secondary endpoint was localization success, which was defined as navigation to within needle biopsy distance of the nodule. This includes center, peripheral, and distal punctures of nodules, as well as adjacent punctures (touching the nodule but not within it). The secondary endpoint was met in 35% of UTB-rEBUS procedures, 65% of electromagnetic navigation procedures, and 90% of robotic bronchoscopy procedures.
The researchers also assessed successful navigation, which was defined as the provider localizing with software or radial ultrasound and passing the needle to make a biopsy attempt. Navigation was successful in 65% of UTB-rEBUS procedures, 85% of electromagnetic navigation procedures, and 100% of robotic bronchoscopy procedures.
“Utilization of robotic bronchoscopy with shape-sensing technology can significantly increase the ability to localize and puncture lesions when compared with standard existing technologies,” Dr. Yarmus said in closing.
He did note that this research was done in a cadaveric model, so “prospective, randomized, and comparative in vivo studies are needed.”
This study was funded by the Association of Interventional Pulmonary Program Directors. Dr. Yarmus disclosed government and societal funding and relationships with Boston Scientific, Veran, Medtronic, Intuitive, Auris, Erbe, Olympus, BD, Rocket, Ambu, Inspire Medical, and AstraZeneca.

Inhaled nitric oxide improves activity in pulmonary fibrosis patients at risk of PH
NEW ORLEANS – In patients with interstitial lung diseases at risk of pulmonary hypertension, inhaled nitric oxide produced meaningful improvements in activity that have been maintained over the long term, an investigator reported here.
Inhaled nitric oxide, which improved moderate to vigorous physical activity by 34% versus placebo in an 8-week controlled trial, has demonstrated long-term maintenance of activity parameters in open-label extension data, presented at the annual meeting of the American College of Chest Physicians.
The treatment was safe and well tolerated in this cohort of subjects at risk of pulmonary hypertension associated with pulmonary fibrosis (PH-PF), said Steven D. Nathan, MD, director of the advanced lung disease and lung transplant program at Inova Fairfax (Va.) Hospital.
The findings to date suggest inhaled nitric oxide (iNO) is a potentially effective treatment option for patients at risk for pulmonary hypertension, which is associated with poor outcomes in various forms of interstitial lung disease, Dr. Nathan said in his presentation, adding that a second cohort of PH-PF patients has been fully recruited and continue to be followed.
“Hopefully, once we show that iNO is positive and validate what we’ve seen with cohort one, then we’ll be moving on to cohort three, which will be a pivotal phase 3 clinical study with actigraphy activity–monitoring being the primary endpoint, and that has been agreed upon by the Food and Drug Administration,” he said.
The actigraph device used in the study, worn on the wrist of the nondominant arm, continuously measures patient movement in acceleration units and allows for categorization of intensity, from sedentary to vigorous, Dr. Nathan explained in this presentation.
“To me, actigraphy activity–monitoring is kind of a step beyond the 6-minute walk test,” he said. “We get a sense of how [patients] might function, based on the 6-minute walk test, but what actigraphy gives us is actually how they do function once they leave the clinic. So I think this is emerging as a very viable and valuable endpoint in clinical trials.”
Dr. Nathan reported on 23 patients with a variety of pulmonary fibrotic interstitial lung diseases randomized to receive iNO 30 mcg/kg based on their ideal body weight (IBW) per hour, and 18 who were randomized to placebo, for 8 weeks of blinded treatment. After that, patients from both arms transitioned to open-label treatment, stepping up to 45 mcg/kg IBW/hr for at least 8 weeks, and then to 75 mcg/kg IBW/hr.
After the 8 weeks of blinded treatment, activity as measured by actigraphy was maintained in the patients receiving iNO, and decreased in the placebo arm (P = .05), according to Dr. Nathan, who added that this difference was largely driven by changes in levels of moderate to vigorous physical activity, which improved in the treatment arm, while declining substantially in the placebo arm.
Clinically significant improvements in moderate to vigorous physical activity were seen in 23.1% of patients in the treatment arm and 0% of the placebo arm, while clinically significant declines in that measure were seen in 38.5% of the treatment group versus 71.4% of the placebo group.
Data from the open-label extension phase, which included a total of 18 patients, show that activity was “well maintained” over a total of 20 weeks, with patients formerly in the placebo arm demonstrating levels of activity comparable to what was achieved in the patients randomized to treatment: “We felt like this supports the clinical efficacy of the nitric oxide effect, that the placebo arm started to behave like the treatment arm,” Dr. Nathan said.
Some adverse events were reported in the study, but none were felt to be attributable to the iNO, according to Dr. Nathan.

Fluoroscopic system can improve targeting of lung lesions
NEW ORLEANS – A novel according to an industry-sponsored, prospective study.
The system, which incorporates fluoroscopic navigation, increased the percentage of cases in which the target overlapped with the lesion, from 60% to 83%. The percentage of cases without any target overlap decreased from 32% to 5%.
“Tomosynthesis-based fluoroscopic navigation … improves the three-dimensional convergence between the virtual target and the actual target,” said Krish Bhadra, MD, of CHI Memorial Medical Group in Chattanooga, Tenn.
Dr. Bhadra presented results with this system at the annual meeting of the American College of Chest Physicians.
He and his colleagues conducted a study of Medtronic’s superDimension navigation system (version 7.2), which provides real-time imaging with three-dimensional fluoroscopy. The system has a “local registration” feature, which uses fluoroscopy and an algorithm to update the virtual target location during the procedure. This allows the user to reposition the catheter based on the location of the lesion.
The researchers tested the system in 50 patients from two centers (NCT03585959). Patients’ lesions had to be larger than 10 mm, not visible endobronchially, and not reachable by convex endobronchial ultrasound. Lesions within 10 mm of the diaphragm were excluded.
The median lesion size was 17.0 mm, 61.2% were smaller than 20 mm, 65.3% were in the upper lobe, and 53.1% had a bronchus sign present. The median distance from lesion to pleura was 5.9 mm.
Dr. Bhadra said the system performed as designed in all cases, and the protocol-defined technical success rate was 95.9% (47/49). Local registration was attempted in 49 patients and was successful in 47 patients (95.9%). In the unsuccessful cases, local registration was not completed based on the system design because the correction distance was greater than 3.0 cm.
The study’s primary endpoint was three-dimensional overlap of the virtual target and the actual lesion, as confirmed by cone-beam computed tomography. Success was defined as greater than 0% overlap after location correction. Target overlap was achieved in 59.6% (28/47) of cases before local registration and 83.0% (39/47) of cases after.
There were six cases in which local registration was successful, but these subjects weren’t evaluable because of failed procedure recording. When those subjects were excluded, target overlap was achieved in 95.1% (39/41) of cases after local registration.
The median percent overlap between the virtual target and the actual lesion was 11.4% before local registration and 32.8% after. The percentage of cases without any target overlap decreased from 31.7% (13/41) before local registration to 4.9% (2/41) after.
Focusing on the two cases without target overlap, Dr. Bhadra noted that he was able to get a biopsy that proved a malignancy in one of those patients. In the other patient, Dr. Bhadra was able to identify features of organizing pneumonia.
“Even though we did not have overlap, we must have been close enough that we were able to get malignant tissue in one [patient] and features of organizing pneumonia in a patient who’s got no history of organizing pneumonia,” Dr. Bhadra said.
He and his colleagues did not evaluate diagnostic yield in this study, but they did assess complications up to 7 days after the procedure.
The team reported one case of pneumothorax, but the patient didn’t require a chest tube. Additionally, there were two cases of bronchopulmonary hemorrhage, but the patients didn’t require any interventions.
This study was sponsored by Medtronic. Dr. Bhadra disclosed relationships with Medtronic, Boston Scientific, BodyVision, Auris Surgical Robotics, Intuitive Surgical, Veracyte, Biodesix, Merit Medical Endotek, and Johnson & Johnson.

Success was defined as greater than 0% overlap after location correction. Target overlap was achieved in 59.6% (28/47) of cases before local registration and 83.0% (39/47) of cases after.
There were six cases in which local registration was successful, but these subjects weren’t evaluable because of failed procedure recording. When those subjects were excluded, target overlap was achieved in 95.1% (39/41) of cases after local registration.
The median percent overlap between the virtual target and the actual lesion was 11.4% before local registration and 32.8% after. The percentage of cases without any target overlap decreased from 31.7% (13/41) before local registration to 4.9% (2/41) after.
Focusing on the two cases without target overlap, Dr. Bhadra noted that he was able to get a biopsy that proved a malignancy in one of those patients. In the other patient, Dr. Bhadra was able to identify features of organizing pneumonia.
“Even though we did not have overlap, we must have been close enough that we were able to get malignant tissue in one [patient] and features of organizing pneumonia in a patient who’s got no history of organizing pneumonia,” Dr. Bhadra said.
He and his colleagues did not evaluate diagnostic yield in this study, but they did assess complications up to 7 days after the procedure.
The team reported one case of pneumothorax, but the patient didn’t require a chest tube. Additionally, there were two cases of bronchopulmonary hemorrhage, but the patients didn’t require any interventions.
This study was sponsored by Medtronic. Dr. Bhadra disclosed relationships with Medtronic, Boston Scientific, BodyVision, Auris Surgical Robotics, Intuitive Surgical, Veracyte, Biodesix, Merit Medical Endotek, and Johnson & Johnson.

NEW ORLEANS – A novel according to an industry-sponsored, prospective study.
The system, which incorporates fluoroscopic navigation, increased the percentage of cases in which the target overlapped with the lesion, from 60% to 83%. The percentage of cases without any target overlap decreased from 32% to 5%.
“Tomosynthesis-based fluoroscopic navigation … improves the three-dimensional convergence between the virtual target and the actual target,” said Krish Bhadra, MD, of CHI Memorial Medical Group in Chattanooga, Tenn.
Dr. Bhadra presented results with this system at the annual meeting of the American College of Chest Physicians.
He and his colleagues conducted a study of Medtronic’s superDimension navigation system (version 7.2), which provides real-time imaging with three-dimensional fluoroscopy. The system has a “local registration” feature, which uses fluoroscopy and an algorithm to update the virtual target location during the procedure. This allows the user to reposition the catheter based on the location of the lesion.
The researchers tested the system in 50 patients from two centers (NCT03585959). Patients’ lesions had to be larger than 10 mm, not visible endobronchially, and not reachable by convex endobronchial ultrasound. Lesions within 10 mm of the diaphragm were excluded.
The median lesion size was 17.0 mm, 61.2% were smaller than 20 mm, 65.3% were in the upper lobe, and 53.1% had a bronchus sign present. The median distance from lesion to pleura was 5.9 mm.
Dr. Bhadra said the system performed as designed in all cases, and the protocol-defined technical success rate was 95.9% (47/49). Local registration was attempted in 49 patients and was successful in 47 patients (95.9%). In the unsuccessful cases, local registration was not completed based on the system design because the correction distance was greater than 3.0 cm.
The study’s primary endpoint was three-dimensional overlap of the virtual target and the actual lesion, as confirmed by cone-beam computed tomography. Success was defined as greater than 0% overlap after location correction. Target overlap was achieved in 59.6% (28/47) of cases before local registration and 83.0% (39/47) of cases after.

Macitentan produces similar results in PAH-SSc and IPAH/HPAH
NEW ORLEANS – Real-world data support the use of macitentan to treat pulmonary arterial hypertension (PAH) associated with connective tissue disease, according to a speaker at the annual meeting of the American College of Chest Physicians.
Outcomes of macitentan (Opsumit) treatment were similar in patients who had PAH associated with systemic sclerosis (PAH-SSc) and patients who had idiopathic PAH (IPAH) or heritable PAH (HPAH), Vallerie McLaughlin, MD, of the University of Michigan, Ann Arbor, said at the meeting.
“Within the limits of a real-world registry, these data add to the growing body of evidence supporting the use of macitentan for treatment in patients with CTD [connective tissue disease],” Dr. McLaughlin said.
She and her colleagues evaluated data from the prospective OPUS registry (NCT02126943) and the retrospective OrPHeUS study (NCT03197688), both of which included patients who were newly started on macitentan.
Dr. McLaughlin presented data on 2,311 patients with IPAH/HPAH and 668 patients with PAH-SSc. She also presented data on patients with PAH-systemic lupus erythematosus and PAH-mixed CTD, but numbers in these groups were small, and outcomes were similar to those in the PAH-SSc group.
Demographic and disease characteristics at the start of macitentan were similar between the IPAH/HPAH and PAH-SSc groups. The median age was 64 years in both groups. The median time from PAH diagnosis was 7.6 months in the IPAH/HPAH group and 8.5 months in the PAH-SSc group.
The median duration of macitentan exposure was 13.4 months in the IPAH/HPAH group and 14.4 months in the PAH-SSc group. The proportion of patients receiving macitentan in combination with other therapies (double or triple combinations) increased from baseline to 6 months in both groups.
Hepatic adverse events occurred in 7.4% of IPAH/HPAH patients and 7.9% of PAH-SSc patients. The most common adverse events among the IPAH/HPAH and PAH-SSc groups in the OPUS registry alone were dyspnea (19% and 26.1%, respectively), peripheral edema (9.8% and 12.4%), fatigue (6.8% and 11.7%), anemia (6.7% and 11.7%), headache (10.2% and 11%), and dizziness (6.7% and 10.7%).
About 39% of patients in both groups discontinued macitentan. Similar proportions in each group discontinued because of adverse events (17% in the IPAH/HPAH group and 18.3% in the PAH-SSc group) and hepatic adverse events (0.2% and 0.7%, respectively).
The proportion of patients with at least one hospitalization was 36.2% in the IPAH/HPAH group and 40.1% in the PAH-SSc group.
The 12-month Kaplan-Meier survival estimate was 92.9% in the IPAH/HPAH group and 91.3% in the PAH-SSc group. The 24-month estimated survival rate was 85.6% and 82.1%, respectively.

Omalizumab results for asthma varied with fixed airflow obstruction, reversibility
NEW ORLEANS – A new analysis suggests However, exacerbation reductions were greatest in patients with high reversibility, and omalizumab only improved lung function significantly in FAO-negative patients with high reversibility.
Nicola Hanania, MD, of Baylor College of Medicine, Houston, presented these findings at the annual meeting of the American College of Chest Physicians.
The findings are from a post hoc analysis of the phase 3 EXTRA study (NCT00314574). This 48-week study enrolled patients who had inadequately controlled, severe asthma despite receiving high-dose inhaled corticosteroids and long-acting beta-agonists.
The patients were randomized to receive omalizumab (n = 427) or placebo (n = 421). Baseline characteristics were similar between the treatment arms.
FAO presence was defined as a postbronchodilator FEV1/FVC (forced expiratory volume in 1 second/forced vital capacity) ratio less than 70%. High reversibility was defined as an increase in FEV1 of 12% or greater after albuterol administration.Omalizumab reduced exacerbations regardless of FAO, but the exacerbation relative rate reductions were greatest in FAO-positive and -negative subgroups with high reversibility.
The exacerbation relative rate reductions with omalizumab versus placebo were as follows:
- 24.8% in the overall population.
- 6.0% in FAO-positive patients with low reversibility.
- 59.8% in FAO-positive patients with high reversibility.
- 17.4% in FAO-negative patients with low reversibility.
- 44.3% in FAO-negative patients with high reversibility.
“So bronchodilator reversibility at baseline was … a correlate of more significant exacerbation reduction than … low reversibility,” Dr. Hanania said. “But the fixed airflow obstruction, whether it was present or not, did not really matter.”
As for lung function improvement, omalizumab conferred a marginal benefit for the overall population, but the improvement was “much more significant” in the FAO-negative patients with high reversibility, according to Dr. Hanania.
At week 48, the least-square mean treatment difference (omalizumab vs. placebo) for absolute FEV1 change from baseline was:
- 68 mL in the overall population.
- 17 mL in FAO-positive patients with low reversibility.
- 2 mL in FAO-positive patients with high reversibility.
- 34 mL in FAO-negative patients with low reversibility.
- 104 mL in FAO-negative patients with high reversibility.
“As lung function improvement by omalizumab appeared to be driven by reversibility, asthma with lower reversibility and fixed airflow obstruction may represent a different phenotype,” Dr. Hanania said. “I think this needs to be looked at.”
This research was funded by Genentech and Novartis. Dr. Hanania disclosed relationships with Genentech, Novartis, AstraZeneca, Boehringer Ingelheim, GSK, Regeneron, and Sanofi.

Patients have good recall on lung cancer screening scan benefits, not risks
NEW ORLEANS – in a recent survey, underscoring the need for ongoing patient education beyond the initial shared decision-making encounter, a researcher said.
While about 9 in 10 patients recalled key information on the benefits, only about 4 in 10 recalled information on risks, according to Erin Hirsch, MSPH, of the Colorado School of Public Health in Aurora.
“This may mean we need ongoing clinician involvement or continued education about this important information, especially if the patients aren’t screening annually,” Ms. Hirsch said in a podium presentation at the annual meeting of the American College of Chest Physicians.
Even fewer patients could correctly recall eligibility criteria for lung cancer screening, which suggests “ongoing clinician involvement” is needed to identify appropriate patients, Hirsch added in her presentation.
Shared decision making about lung cancer screening, which is supposed to entail a balanced patient-provider conversation about eligibility, risks, and benefits, is required by the Centers for Medicare & Medicaid Services to cover the cost of lung cancer screening as a preventative service, Hirsch noted in her presentation.
However, it’s largely unknown to what extent patients due for an annual screening recall information that should have been imparted in that initial discussion.
“The gap in knowledge centers around the fact that shared decision making is only required for baseline scan, but screening is recommended on an annual basis,” she said.
To test patient recall, Hirsch and colleagues developed a knowledge survey including 34 questions about lung cancer screening eligibility, risks, and benefits. The surveys went out by mail or email to 228 patients who had a baseline screening CT scan 6-12 months earlier; a total of 53 complete responses were included in the analysis, which focused on seven key questions about benefit, risk, and eligibility.
Recall was “excellent” for the benefit questions, Ms. Hirsch said, with 91% of patients able to recall that a computed tomography (CT) scan is better at detecting a possible lung cancer than a chest x-ray, while 87% recalled that without screening lung cancer is often found at a later stage when cure is less likely.
By contrast, a “moderate” amount (40%) remembered that a CT scan can suggest the patient has lung cancer when in fact they do not, she said, and only 38% recalled that radiation exposure was one of the harms of lung cancer screening, she added.
Eligibility recall was “poor,” she added, with only 21% affirming that not all current and former smokers need to be screened for lung cancer. Just 8% recalled that 55 years is the age at which beginning lung cancer screening is recommended, and 4% knew that 30 is the minimum number of pack-years required to be eligible for screening.
While these results may have clinical implications, Ms. Hirsch acknowledged a number of limitations to this pilot study. Among those was the fact that the content of the initial shared decision-making conversation could not be assessed: “We assumed that the patients were exposed to the information asked about in the survey ahead of time, but we can’t say for sure if that was true,” she explained.
Ms. Hirsch and coauthors disclosed no relationships relevant to their study.

The surveys went out by mail or email to 228 patients who had a baseline screening CT scan 6-12 months earlier; a total of 53 complete responses were included in the analysis, which focused on seven key questions about benefit, risk, and eligibility.
Recall was “excellent” for the benefit questions, Ms. Hirsch said, with 91% of patients able to recall that a computed tomography (CT) scan is better at detecting a possible lung cancer than a chest x-ray, while 87% recalled that without screening lung cancer is often found at a later stage when cure is less likely.
By contrast, a “moderate” amount (40%) remembered that a CT scan can suggest the patient has lung cancer when in fact they do not, she said, and only 38% recalled that radiation exposure was one of the harms of lung cancer screening, she added.
Eligibility recall was “poor,” she added, with only 21% affirming that not all current and former smokers need to be screened for lung cancer. Just 8% recalled that 55 years is the age at which beginning lung cancer screening is recommended, and 4% knew that 30 is the minimum number of pack-years required to be eligible for screening.
While these results may have clinical implications, Ms. Hirsch acknowledged a number of limitations to this pilot study. Among those was the fact that the content of the initial shared decision-making conversation could not be assessed: “We assumed that the patients were exposed to the information asked about in the survey ahead of time, but we can’t say for sure if that was true,” she explained.
Ms. Hirsch and coauthors disclosed no relationships relevant to their study.
