New research shows omalizumab to be a promising treatment or prevention option for virus-induced asthma exacerbations, an important public health issue that affects every child with asthma.
Acute asthma exacerbations, including the asthma attacks caused by viral infections like the common cold, lead to missed days of school and a decreased quality of life for asthmatic children and their families. Furthermore, asthma disproportionately affects low-income, minority and inner-city populations with higher morbidity and mortality rates.
“We previously showed that treatment with omalizumab can reduce the length of viral infection and it can also improve interferon/antiviral responses. We wondered, then, if omalizumab could decrease the time that children with asthma have symptoms from upper respiratory illnesses,” James Gern, MD, FAAAAI, with University of Wisconsin-Madison School of Medicine and Public Health said.
The Preventative Omalizumab or Step-up Therapy for Severe Fall Exacerbations (PROSE) study randomized 478 asthmatic children, aged 6 to 17, from low-income census tracts to receive either guidelines-based asthma care, fluticasone boost or add-on omalizumab. Cold symptom scoring sheets were collected weekly over the four-month treatment period during the fall seasons of 2012 or 2013.
Colds were assessed weekly and identified as increased symptoms: runny nose, stuffy nose, sneezing, cough and sore throat. In total, 5,873 cold assessments were completed and 1,034 (18%) symptomatic illnesses were detected.
In total, rates of colds in participants treated with add-on omalizumab were decreased (0.15/sample) compared to participants who only received guidelines-based asthma care (0.20/sample), a difference of 27%. Fluticasone boosts (0.17) had no significant effect on cold rates.
“Rates of colds per sample were significantly reduced in the omalizumab group, and this effect was seen across asthma treatment steps with the same rate of reduction observed in children with moderate and severe persistent asthma,” Gern said.
