Abstract

Background

Atezo, a monoclonal antibody targeting PD-L1, is an approved therapy for locally advanced/metastatic urothelial cancer. The pivotal IMvigor210 and IMvigor211 phase II and III trials excluded pts with significant pre-existing AID. The SAUL study (NCT02928406) in pts more representative of real-world practice showed median overall survival (OS) of 8.7 mo and safety consistent with previous atezo trials [Sternberg, Eur Urol 2019]. We analysed outcomes in pts with a history of AID.

Methods

Pts with locally advanced/metastatic urinary tract carcinoma, including pts ineligible for IMvigor211, received atezo 1200 mg q3w until loss of clinical benefit or unacceptable toxicity. The primary endpoint was safety, including adverse events of special interest (AESIs) for atezo as defined in the protocol. OS was a secondary endpoint. Subgroup analyses of AID pts were prespecified.

Results

Of 1004 pts enrolled from Nov 2016 to Mar 2018, 997 received atezo. In 35 pts presenting with AID, the most common pre-existing conditions were psoriasis (n = 15), thyroid AID (n = 5) and rheumatoid arthritis (n = 4). Compared with non-AID pts, AID pts had numerically more AESIs (46% vs 30%; grade ≥3 14% vs 6%) and treatment-related grade 3/4 AEs (26% vs 12%), but there were no relevant increases in treatment-related deaths (0% vs 1%) or AEs leading to atezo discontinuation (9% vs 6%). Pre-existing AID worsened in 6 pts: flares subsequently improved or resolved in 4 pts (without stopping atezo in 3 pts) but were unresolved in 2 pts (rash in 1 pt continuing atezo, psoriasis in 1 pt who discontinued atezo). In the 962 non-AID pts, new immune-related AEs were infrequent (6% hypothyroidism, 4% hyperthyroidism, 2% pneumonitis, 1% colitis). Efficacy was similar in AID vs non-AID pts (median OS 8.2 vs 8.8 mo, respectively; 1-year OS 31% vs 42%; disease control 51% vs 39%; median PFS 4.4 vs 2.2 mo).

Conclusions

In 35 atezo-treated pts with pre-existing AID, incidences of AESIs and treatment-related AEs appeared acceptable. AEs were manageable and rarely led to atezo discontinuation. Treating these pts requires caution but AID is not a barrier to atezo therapy per se.
