e15076 Background: Immune checkpoint inhibitors (ICIs) are increasingly used in the management of cancer. High grade irAEs are uncommon but can be severe and require hospital admission. There is an urgent need for early identification and triage of patients with irAEs in order to improve their management and outcomes. Methods: We established Immunotherapy toxicity (ITOX) team as the first in nation inpatient service at DFCI and Brigham and Women's Hospital (BWH) along with our partners at Massachusetts General Hospital (MGH) that is specifically devoted to mitigating irAEs. The ITOX service is consistent of 2 PAs and a medical oncology attending with an expertise in immunotherapy. The service utilizes algorithms that are modified from the ASCO and NCCN guidelines by our medical subspecialty experts at BWH. The service uses a multi-disciplinary approach with around the hour consulting service from experts in the field including GI, pulmonary, endocrinology and others. We leveraged EPIC to triage patients who are admitted to BWH and have ever received or currently on immune checkpoint inhibitors (ICIs). The daily list generated by EPIC is then curated manually by a PA to identify patients with potential irAEs. Results: A total of 138 patients with high grade irAEs were admitted to BWH between June 2018 and June 2019. Seventy percent of the 201 irAEs- related admissions were to ITOX service (70% accuracy in triaging). Most common irAEs was colitis (31%), pneumonitis (28%) and hepatitis (13%) which is consistent with the most common reported irAEs due to ICIs. Eighty five percent of the patients had grade 3 irAEs and 15% were admitted with life threatening grade 4 adverse events. About half of the patient had received ICI monotherapy; 33% received combination of ICI and non-ICI (chemotherapy or targeted therapy) and 17% received combination of ICIs. Most patients responded to steroids and only 9% had steroid-refractory irAEs requiring other immunosuppressive agents. The average length of stay for irAEs-related admission was 11 days with readmission rate of 26% within a year. Over 50 patients consented for tissue and blood biospecimen collection at the time of toxicity. Conclusions: We demonstrated the feasibility of empowering EMR to accurately triage patients with suspected irAEs to the ITOX service that is supported by institution developed guidelines and specialists. Our model is adaptable in major academic centers and can have major impact on quality improvement and future research studies that can be conducted in this unique setting.

IntroductionLittle evidence exists on the safety and efficacy of the rechallenge of immune checkpoint inhibitors (ICIs) after immune-related adverse events (irAEs) in patients with cancer.MethodsWe searched PubMed, Web of Science, Embase, and Cochrane for articles on ICI rechallenge after irAEs for systemic review and meta-analysis. The outcomes included the incidence and associated factors for safety and objective response rate (ORR) and disease control rate (DCR) for efficacy.ResultsA total of 789 ICI rechallenge cases from 18 cohort studies, 5 case series studies, and 54 case reports were included. The pooled incidence of all-grade and high-grade irAEs after rechallenge in patients with cancer was 34.2% and 11.7%, respectively. Compared with initial ICI treatment, rechallenge showed a higher incidence for all-grade irAEs (OR, 3.81; 95% CI, 2.15–6.74; p < 0.0001), but similar incidence for high-grade irAEs (p > 0.05). Types of initial irAEs (pneumonitis and global irAEs) and cancer (non-small cell lung cancer and multiple cancer) recapitulated these findings. Gastrointestinal irAEs and time interval between initial irAEs and ICI rechallenge were associated with higher recurrence of high-grade irAEs (p < 0.05), whereas initial anti-PD-1/PD-L1 antibodies were associated with a lower recurrence (p < 0.05). Anti-PD-1/PD-L1 antibodies rechallenge was associated with a lower all-grade irAE recurrence (p < 0.05). The pooled ORR and DCR after rechallenge were 43.1% and 71.9%, respectively, showing no significant difference compared with initial ICI treatment (p > 0.05).ConclusionsICI rechallenge after irAEs showed lower safety and similar efficacy outcomes compared with initial ICI treatment.Systematic Review RegistrationPROSPERO, identifier CRD42020191405.

Abstract INTRODUCTION In several cancers treated with immune checkpoint inhibitors (ICIs), a remarkable association between the occurrence of immune-related adverse events (irAEs) and superior oncological outcomes has been reported. This effect has hitherto not been reported in the brain. This study aimed to investigate the relation between irAEs and outcomes in brain metastases (BM) patients treated with both local treatment to the brain (LT; i.e. surgery and/or radiation) and ICIs. METHODS This study is a retrospective cohort analysis of patients treated for non-small cell lung cancer (NSCLC) BMs in a tertiary institution in Boston, MA. Outcomes of interest were overall survival (OS) and intracranial progression-free survival (IC-PFS), measured from the time of LT. Sensitivity analyses were performed to account for immortal time bias (i.e., patients who live longer receive more cycles of ICIs and thus have more opportunity to develop an irAE). RESULTS A total of 184 patients were included; 62 (33.7%) were treated with neurosurgical resection and 122 (66.3%) with upfront brain radiation. irAEs occurred in 62 patients (33.7%). After adjusting for lung-Graded Prognostic Assessment, type of LT, type of ICI, newly diagnosed vs. recurrent BM, BM size and number, targetable mutations, and smoking status, irAEs were strongly associated with better OS (HR 0.33, 95% CI 0.19 – 0.58, p < 0.0001) and IC-PFS (HR 0.41; 95% CI 0.26 – 0.65; p = 0.0001). Landmark analysis including only patients who received more than 3 cycles of ICI (n = 133) demonstrated similar results for OS and IC-PFS, as did sensitivity analysis adjusting for the number of cycles administered (HR range 0.36 – 0.51, all p-values < 0.02). CONCLUSIONS After adjusting for known prognostic factors, irAEs strongly predict superior outcomes after LT in NSCLC BM patients. Sensitivity analysis suggests that this is unlikely due to immortal time bias.

Abstract Background Immune checkpoint inhibitors (ICI) have become standard treatment in different tumor entities. However, safe treatment with ICI targeting the PD-1/PD-L1 axis requires early detection of immune-related adverse events (irAE). There exist different questionnaires of drug manufacturers for the detection of irAE that have not been validated so far. Methods The prospective non-interventional ST-ICI trial studied treatment with PD-1/PD-L1 ICI alone or combined with radiotherapy. In the current analysis, the detection rate of self-reported irAE with a patient questionnaire containing 41 different questions was compared to clinician-reported irAE. Results Between April 2017 and August 2019, a total of 104 patients were prospectively enrolled. NSCLC (44%) and HNSCC (42%) were the most frequent tumor entities. A total of 784 questionnaires were collected. A total of 29 irAE were reported by clinicians. The most frequent irAE was hypothyroidism (9%), followed by skin reactions (5%), hepatitis (4%), diarrhea (3%), and pneumonitis (3%). Questions that became significantly more often positive at time points of clinician-reported irAE were “weight change”, “difficulty to grip things”, “bloody or mucous stool” and “insomnia”. Self-reported organ-specific questions detected at least 50% of clinician-reported irAE of gastrointestinal, lung, endocrine, and skin irAE. It was not possible to detect hepatic irAE with the questionnaire. Conclusion Questionnaires can help to detect gastrointestinal, lung, endocrine, or skin irAE, but not hepatic irAE. Questions on “weight change” and “insomnia” may help to increase the detection rate of irAE, besides organ-specific questions. These results are a valuable contribution to the future development of a specific and practicable questionnaire for early self-reported detection of irAE during ICI therapy in cancer patients.
