In a real-world study of asthma patients,
The data fill a gap, according to Sushan Gupta, MD, who presented the results at the annual meeting of the American College of Chest Physicians. “There’s some ample real-world data that shows that biologics reduce the incidence of asthma exacerbation, but the data regarding what happens after an exacerbation is still lacking, especially real-world data,” said Dr. Gupta, who is a resident at Carle Foundation Hospital in Champaign, Ill.
The findings were encouraging. “Patients with severe asthma on biologics fare well even after an exacerbation event, which includes a reduced incidence of hospitalization, ICU admission, and need for mechanical ventilation. We did not have any patient in the biologic group that required intubation, so that is pretty significant as compared to other patients who did not receive biologics,” said Dr. Gupta.
The results weren’t surprising, but underscore the benefits of biologics, according to Brittany Duchene, MD, who moderated the session where the results were presented. “I think it reinforced that they’re really good drugs,” said Dr. Duchene, who is a pulmonary critical care physician at Northeastern Vermont Regional Hospital, St. Johnsbury.
Although the study was retrospective, it suggests that the threshold for initiating biologics could potentially be lowered for patients with uncontrolled asthma despite adequate use of inhalers, according to Dr. Gupta. “Should that threshold be lower, and would that improve the overall morbidity and eventually the health care cost of utilization? Our study does not prove any of those data, but moving forward that data will also come out.”
Dr. Duchene noted that the accumulating scientific and clinical data for biologics is “really, really strong.” She also speculated that biologics could be used increasingly in the acute setting, which she admitted is a controversial topic. “I think there’s going to be a lot more push to early initiation, and you can see from the [new] study that it decreased a lot of hospitalizations.”
Dr. Gupta emphasized the need for prospective studies, and Dr. Duchene agreed that any such change would need to be patient centric, considering the diversity of available biologics. “It depends what their true issue is. The broader the biologic [mechanism of action], probably the more success you’ll have. I’ve found there’s not a pure allergic or a pure eosinophilic asthma patient. They’re usually more a combination.”
Some key questions remain about biologics treatment, especially in the long term. These include when a patient should be switched from one biologic to another, and whether biologic treatment should be continued over the patient’s lifetime and potential long-term side effects. “I think that data is still evolving and will come to us with time,” said Dr. Gupta.
The researchers analyzed retrospective data from 316 asthma patients treated with biologics and 9,645 treated with nonbiologic therapy between February 2018 and February 2023 at a tertiary care teaching hospital in the Midwest. There was a higher proportion of females in the biologics (69.7%) and nonbiologics groups (63.8%, P = .032), but there was no significant difference in the proportion of Whites in the biologics and nonbiologics groups (78.2% vs. 74.3%, P = .103).
The lack of a difference in racial groups was a surprise, according to Dr. Duchene, especially since other studies have noted disparities in biologic therapy among asthma patients.
Among the biologics group, 0.9% were hospitalized during the study period, compared with 6.5% of the nonbiologics group (P = .00006). They also had fewer ICU visits (0.3% vs. 1.8%; P = .04).
Dr. Gupta’s team attempted to subdivide the data by individual biologic, but there was no statistical significance in outcomes between biologics, perhaps because of the relatively small sample size.
Dr. Gupta noted that his group’s results are generally similar to other studies, including a U.S. study that found a decrease in exacerbation rates after staring or switching biologics and a slightly higher prevalence of biologics use among White patients (77% of biologic users versus 71% of nonbiologics users). A study in southwestern England found fewer ED visits and hospitalizations among patients on biologics.
