Long-Term Effectiveness of Anti-IL-4R Therapy Following Suboptimal Response to Anti-IL-5/5R Therapy in Severe Eosinophilic Asthma

Article

BACKGROUNDDupilumab is an anti-IL-4R monoclonal antibody (mAb) with proven efficacy in severe eosinophilic asthma (SEA). A suboptimal response to anti-IL-5/5R mAbs is seen in some patients with ongoing evidence of type 2 (T2) inflammation.OBJECTIVETo understand whether targeting IL-13 pathways with dupilumab in these patients may lead to better clinical outcomes.METHODSWe performed a retrospective analysis of the extended clinical effectiveness of dupilumab up to 2 years of treatment in patients with SEA who had not responded adequately to anti-IL-5/5R biologics. The ability to achieve clinical remission and the change in the remission domains of exacerbation rate (AER), maintenance oral corticosteroid dose (mOCS), lung function (forced expiratory volume in 1 second), and asthma control (Asthma Control Questionnaire 6) were recorded.RESULTSThirty-seven patients (mean age 41 years, 70% female) were included in the analysis. The mean (standard deviation) AER fell by almost 90% from 3.16 (1.28) at dupilumab initiation to 0.35 (0.72) after 1 year. The median (interquartile range) mOCS dose (n = 20) fell from 10 (5-25) mg to 0 (0-5) mg at 1 year, with 14 of 20 (70%) able to stop prednisolone altogether. Clinical remission was achieved in 16 of 37 (43%). Patients who achieved remission had a higher pre-IL-5/5R fractional exhaled nitric oxide (FeNO) level (85 [39-198] parts per billion [ppb] vs 75 [42-96] ppb, P = .03).CONCLUSIONSSignificant improvements in clinical outcomes are possible after a switch to dupilumab in patients experiencing a suboptimal response to anti-IL-5/5R therapies. A higher FeNO in poor responders to anti-IL-5/5R who achieve remission with dupilumab is suggestive of an IL-13-driven subphenotype of T2-high asthma in which the eosinophil appears unlikely to play a key role in the disease pathogenesis.

Dupilumab-associated head and neck dermatitis shows a pronounced type 22 immune signature mediated by oligoclonally expanded T cells

AbstractDupilumab, an IL4R-blocking antibody, has shown clinical efficacy for atopic dermatitis (AD) treatment. In addition to conjunctivitis/blepharitis, the de novo appearance of head/neck dermatitis is now recognized as a distinct side effect, occurring in up to 10% of patients. Histopathological features distinct from AD suggest a drug effect, but exact underlying mechanisms remain unknown. We profiled punch biopsies from dupilumab-associated head and neck dermatitis (DAHND) by using single-cell RNA sequencing and compared data with untreated AD and healthy control skin. We show that dupilumab treatment was accompanied by normalization of IL-4/IL-13 downstream activity markers such as CCL13, CCL17, CCL18 and CCL26. By contrast, we found strong increases in type 22-associated markers (IL22, AHR) especially in oligoclonally expanded T cells, accompanied by enhanced keratinocyte activation and IL-22 receptor upregulation. Taken together, we demonstrate that dupilumab effectively dampens conventional type 2 inflammation in DAHND lesions, with concomitant hyperactivation of IL22-associated responses.
