Session Title: T Cell Biology and Targets in Autoimmune Disease Poster I
Session Type: ACR Poster Session B
Session Time: 9:00AM-11:00AM
Patients with auto-immune or inflammatory diseases (AID) treated by immune check-points inhibitors (ICI) are intrinsically susceptible to develop immune related adverse events (irAE). We conducted this study to describe and analyze the tolerance and efficiency of anti-PD-1 antibodies in AID patients and to look for a clinical association between these preexisting immune conditions and patient’s outcome.
We described patients with AID treated by ICI and conducted a prospective study in patients receiving anti-PD-1 antibody included in the registry REISAMIC (“Registry of Severe Adverse Events of Immunomodulating Monoclonal Antibodies in Oncology”) between 1st June 2014 and 31th December 2016. We analyzed the association between preexisting autoimmune disorder and irAE-free survival and overall survival.
We described 54 AID patients treated by ICI (mainly anti-PD-1 antibodies) including 45 AID patients which were analyzed and compared to non-AID patients among 397 patients from the registry REISAMIC. Cancer diagnoses included melanoma in 40 cases (74,1%), NSCLC in 10 cases (22,2%) and other cancers in 4 cases (2 renal cell carcinoma and urothelial carcinoma). Preexisting autoimmune or inflammatory diseases were vitiligo (n=17, 31,5%), cutaneous psoriasis (n=13, 32,5%), auto-immune thyroiditis (n=8, 20%), Sjögren syndrome (n=4, 10%), rheumatoid arthritis (n=4, 10%), auto-immune cytopenia (n=3, 17,5%), spondyloarthritis (n=2, 5%), multiple sclerosis (n=2, 5%) hidradenitis suppurativa (n=2, 5%), and in one case each: myasthenia gravis, polymyalgia rheumatica, polyarteritis nodosa, sarcoidosis, chronic cutaneous lupus, type 1 diabetes, primary nephrotic syndrome, acute tubulo-interstitial nephritis and aseptic abscesses syndrome. 10 patients had two concomitant different AID (18.5%). In 23 cases (42.6%), patient presented at least one grade 2 CTCAE irAE. Among them, 13 irAE (57%) were associated with a preexisting AID: increase of cutaneous psoriasis, development of psoriatic arthritis and pustular psoriasis, extension of vitiligo, hyperthyroidism, exacerbation of Sjögren’s syndrome, myasthenia crisis, polyarthritis or mesenteric abscesses leading to death. Eleven patients developed irAE which were not associated with the AID. 33 patients (61.1%) were alive at the last follow-up with a median time of 6.3 months (range 4.1-9.7 months). 19 patients (35.2%) pursued anti-PD-1 treatments at last follow-up with a median time of 4.9 months (range 3.4-7 months).
The irAE free survival was shorter in AID patients (median=5.4 months) as compared with non-AID patients (median=13 months, p=2,1.10-4). Overall survival in AID patients did not differ to the one observed in non-AID patients (p= 0.38).
In patients treated by anti-PD-1 antibodies, autoimmune and inflammatory diseases was associated with a higher risk of immune related adverse events and particularly flares which could be severe and fatal. AID and non-AID patient’s overall survival were not different. These points increase the importance of networks of collaborations between oncologists, organs specialists, and clinical immunologists to improve patients care.
