Before re-challenging a patient with ICI after grade 1-2 pneumonitis, do you re-image to confirm resolution of pneumonitis?
Grade 1 pneumonitis is defined as confined to one lobe of the lung or <25% of the total lung parenchyma, while grade 2 pneumonitis is defined as involving more than one lobe of the lung or 25-50% of the lung parenchyma. Grade 1 pneumonitis is typically an incidental finding on CT in an asymptomatic ...
Should the use of avacopan be limited to those patients at increased risk of steroid toxicity given the anticipated high cost of this medication?
Once Avacopan is available for clinical use in the treatment of patients with AAV, providers will need to carefully weigh risks and benefits of the medication while considering other factors including cost.The ADVOCATE trial used a novel glucocorticoid toxicity index that captures common GC-related ...
Are there particular subsets of AAV patients in which avacopan is more effective?
The following answer was jointly drafted by Dr. Peter Merkel and Dr. David Jayne:Patients in the ADVOCATE trial were stratified at entry according to time of diagnosis (new/relapsing), diagnosis (GPA/MPA), ANCA serotype (PR3/MPO), and background immunosuppressive (cyclophosphamide/rituximab) with re...
How should the results of the ADVOCATE trial be applied in AAV patients who receive rituximab induction and maintenance therapy?
The following answer was jointly drafted by Dr. Peter Merkel and Dr. David Jayne:The data from ADVOCATE indicate that patients with granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) treated with avacopan 30 mg twice daily and prednisone placebo were able to achieve remission w...
Is there a period of time after which you would not resume ICI after a patient has had an irAE and required a prolonged steroid taper?
Typically if a patient has required treatment with steroids for four to six months, it was because their irAE was significant (grade 2-4) and refractory to initial treatment. If the patient received combination immunotherapy, such as anti-CTLA-4 and anti-PD-1 agents, one could consider resuming the ...
Would the need for infliximab/MTX/nonsteroidals to control initial irAE affect your decision to rechallenge these patients with ICI?
Infliximab and methotrexate are generally used in irAE grades 3 or 4, or in grade 2 irAEs that are refractory to initial treatment with steroids. Methotrexate is typically used for irAEs of the musculoskeletal system, such as inflammatory arthritis or myositis. Infliximab tends to be used in the set...
How long would you recommend that a patient continues guselkumab prior to deciding that the therapy is not effective?
Many trials have a placebo-controlled period of 12-24 weeks. Thereafter, all patients receive active treatment. Even if the original treatment allocation remains unknown to the patient and doctor, they know that from that moment on, everyone receives active treatment. This will have an influence on ...
Is your approach to managing immune related adverse events altered at all in light of COVID-19?
First of all, I wish to thank @Dr. First Last from Johns Hopkins/Sibley for his advice addressing this critical topic.We are all witnessing a rapidly evolving crisis that none of us have been prepared for and it is the right thing to quickly consider as best as we can how the COVID-19 pandemic shoul...
Do the results of FIBRONEER-ILD change your approach to antifibrotic treatment in patients with sarcoidosis related PPF?
According to the FIBRONEER-PPF data, no sarcoidosis-specific outcomes have been reported, and one can only infer that the sarcoidosis-related PPF subpopulation has tracked similarly to the other ILD subtypes, which is a big assumption. It is important to remember that in the INBUILD study, which exa...
How will you incorporate nerandomilast into your treatment algorithm for autoimmune ILD with progression, particularly relative to sequencing with immunosuppression?
The sequencing of therapy in CTD-related PPF remains unclear. Recent data suggest that immunosuppression may not alter clinical outcomes in fibrotic ILDs, including those associated with systemic autoimmune disorders (Pugashetti et al., PMID 42432856). In the FIBRONEER-ILD study, nerandomilast impro...
