Immune checkpoint inhibitors have been approved as adjuvant therapy. Adverse immune events occurred during the administration of treatment, and delayed immune-related events have low incidence. A 66-year-old man was treated for hypopharynx cancer in 2012. In 2019, he was treated for a new oropharynx cancer. After undergoing surgery and complete response, the patient received nivolumab as adjuvant treatment. 5 months after the last dose of nivolumab, he presented with grade III diarrhea and abdominal pain for 3 weeks. Rectoscopy showed infiltration of mucous by lymphocytes. Corticosteroid was started resulting in a rapid decrease in symptom severity. With the increasing immune checkpoint inhibitors in adjuvant therapy, strict surveillance and education of patient in remission is necessary.

Cancer is one of the most deadly diseases in the modern world. The last decade has witnessed dramatic advances in cancer treatment through immunotherapy. One extremely promising means to achieve anti-cancer immunity is to block the immune checkpoint pathways – mechanisms adopted by cancer cells to disguise themselves as regular components of the human body. Many review articles have described a variety of agents that are currently under extensive clinical evaluation. However, while checkpoint blockade is universally effective against a broad spectrum of cancer types and is mostly unrestricted by the mutation status of certain genes, only a minority of patients achieve a complete response. In this review, we summarize the basic principles of immune checkpoint inhibitors in both antibody and smallmolecule forms and also discuss potential mechanisms of resistance, which may shed light on further investigation to achieve higher clinical efficacy for these inhibitors.

Immune checkpoint inhibitors have drastically changed in the treatment of many kinds of malignancies, especially malignant melanoma. The focus of the recent experiments has not only been on their efficacy but also immune-related adverse events (irAEs). We report a case of fulminant hepatitis due to nivolumab. In this case, the patient had undergone long-term nivolumab therapy. He did not complain of any symptoms but his liver enzyme levels were extremely elevated (grade 4). We promptly decided to start oral corticosteroids in the patient. His liver function rapidly improved. The dose of corticosteroids was gradually reduced. Our case demonstrates that sudden onset fulminant hepatitis can occur despite the safe use of long-term nivolumab therapy. The irAE can improve rapidly with proper corticosteroid treatment. This report will be useful for the physicians who always use immune checkpoint inhibitors.

Steroid Refractory

2655 Background: Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of cancer with significantly improved outcomes, but these agents have a unique spectrum of toxicities known as immune-related adverse events (irAEs). The recommended treatment for non-endocrine toxicities is steroid based. However, a subset of patients (pts) is steroid-refractory and requires second-line immunosuppression. There is very little evidence regarding this population. In this retrospective study we report the 1) incidence 2) type of treatment used 3) natural history and 4) potential predictors of steroid-refractory irAE at a major academic medical center. Methods: The Research Patient Database Registry at Mass General Brigham was used to identify pts treated with an ICI from 1/5/2017 to 6/1/2019. Pharmaceutical records identified a subset of the cohort received a second-line immunosuppressive agent within a 15-month period after ICI. For pts with steroid-refractory irAE additional information was collected: demographics, ICI regimen, type/#/and severity of irAE, clinical characteristics, # of admissions, length of stay (LOS), amount and duration of steroid therapy, second line immunosuppression type, treatment discontinuation rates, response, and outcome of re-challenge. Multivariate logistic regressions were used to predict risk of refractory toxicity and study the association of different variables (age, sex, race, marital status, cancer and ICI types) with refractory toxicities. Results: We identified 61 pts (1.4%) with steroid-refractory irAEs (48 colitis, 4 myocarditis, 6 pneumonitis, 3 neurologic) out of the total ICI cohort (N=4,325). 60.7% received ICI monotherapy. 24.6% received ICI in the adjuvant setting. Median length of steroid duration was 68 days with max of 1135 days. Despite use of second line immunosuppression, 25.8% of pts were never able to discontinue steroids. Majority of pts (72.1%) had at least one hospitalization with median LOS of 7.5 days. 93.4% of pts permanently discontinued the ICI responsible for the irAE. Thirteen pts (21.3%) were later re-challenged with ICI and 7 (53.8%) of these developed a subsequent irAE. Anti-CTLA-4 therapy was associated with a 10-fold risk of refractory toxicity compared to PD-1 (p<.05). Best tumor response was complete response in 21.3% and partial response in 26.2%. Among different cancer types, melanoma was most strongly associated with refractory events (OR 2.97 in comparison to thoracic malignancy). Conclusions: Refractory toxicity is uncommon but leads to high rates of ICI discontinuation, frequent hospitalizations, and a long duration of illness with exposure to prolonged and high-doses of steroids. There is an urgent need for further investigation into predictive factors for steroid-refractory toxicity given that ICI is being used more frequently and in earlier lines of treatment.

BACKGROUND: The albumin-globulin ratio (AGR) could be a prognostic biomarker in patients with cancer, although the data is limited in patients treated with immune-checkpoint inhibitors (ICIs). OBJECTIVES: We aimed to evaluate the association between AGR and survival in ICI-treated patients. METHODS: The data of 212 advanced-stage patients were retrospectively evaluated in this cohort study. The association between AGR with overall (OS) and progression-free survival (PFS) were evaluated with multivariate analyses. Additionally, receptor operating curve (ROC) analysis was conducted to assess the AGR’s predictive power in the very early progression (progression within two months) and long-term benefit (more than twelve months survival). RESULTS: The median AGR was calculated as 1.21, and patients were classified into AGR-low and high subgroups according to the median. In the multivariate analyses, patients with lower AGR (< 1.21) had decreased OS (HR: 1.530, 95% CI: 1.100–2.127, p= 0.011) and PFS (HR: 1.390, 95% CI: 1.020–1.895, p= 0.037). The area under curve of AGR to detect early progression and long-term benefit were 0.654 (95% CI: 0.562–0.747, p= 0.001) and 0.671 (95% CI: 0.598–0.744, p< 0.001), respectively. CONCLUSIONS: In our experience, survival with ICIs was impaired in patients with lower AGR. Additionally, the AGR values could detect the very early progression and long-term benefit ICIs.

e21591 Background: Immune checkpoint inhibitors (CPI) are widely used in metastatic melanoma (MM), where it has markedly improved survival outcomes. ICI induced autoimmune adverse reactions (irAE) manifest in all organ systems and are due to over-activation of the immune system. Clinically relevant irAE are colitis and hepatitis as drivers of morbidity and mortality. Methods: Data was collected from a single centre (Princess Alexandra Hospital) from the electronic medical records system and immunotherapy prescribing software. Patient demographics, treatments, complications and outcomes were recorded from 2016-2019. Eligible patients had to have received immunotherapy (pembrolizumab, ipilimumab, or nivolumab) and experienced colitis or hepatitis toxicity. Trial patients were excluded. Results: The cohort of 337 patients who had received immune therapy, 18% (n = 61) had hepatitis or colitis, mean age was 56 years, 64% male. The majority were stage 4d 28% (n = 17). Braf wildtype accounted for 56% (n = 34). The highest rates of irAE occurred on combination ipilimumab and nivolumab 56% (n = 34), 10% nivolumab (n = 6), 3% (n = 2) ipilimumab, and 31% (n = 19) pembrolizumab monotherapy. Colitis affected 61% of patients (n = 37), 30% (n = 18) were grade 3 severity. Hepatitis affected 48% (n = 29), 18% (n = 32) were grade 1. The majority required oral steroids (80%, n = 49), followed by intravenous steroids (51%, n = 31), infliximab (18%, n = 11) and mycophenolate in 5% (n = 3). Hospitalisation occurred in 56% (n = 34), 20% (n = 12) requiring treatment cessation. Progressive disease occurred in 62% (n = 38), and 13% (n = 8) had a complete response. Conclusions: The findings of this analysis mirror current literature with immunotherapies used, rates and severity of irAE. The management of irAE also aligned with current guidelines. Further research is required to investigate patient factors increasing the risk of developing irAE, and ideal treatment regimens. Analysing this large cohort, the incidence of toxicity was 17%, predominantly colitis followed by hepatitis. Patients were severely impacted requiring significant interventions to manage toxicity, hospitalisation and morbidity.

e18092 Background: There is limited data on outcomes for gynecologic cancer patients treated with immune checkpoint inhibitors (ICI) outside the scope of clinical trials. Here we present our Institutional experience with a cohort of endometrial (EC) and ovarian cancer (OC) treated with ICI. Methods: 59 patients who received ICI were included (23 OC and 36 EC). Progression-free (PFS) and Overall survivals (OS) were determined by Kaplan-Meier (KM) curve and log rank test. Comparison of duration of response (DOR) and stable disease (DOSD) was done with unpaired t-test or one-way ANOVA. Rates of objective response (ORR) including partial response (PR) and complete response (CR), and stable disease (SD) were compared by Fischer’s exact test. Results: Median age was 66 years. 23 patients were microsatellite stable (MSS), 23 microsatellite instability high (MSI-H). Median number of prior lines was 2 (0-11). PFS and OS for EC and OC were overlapping; therefore outcomes for both were combined [(PFS 6.4m OC vs 7.3 m EC, p = 0.61), (OS 15.9 m OC vs 14.2 m EC, p = 0.78)]. Response rates consisted of 20.3% PR, 8.5% CR, 37.3% SD. Differences in responses were noted for clear cell carcinoma (CC) (33.3% PR, 11.1% CR, 33.3% SD) and MSI-H (36.4% PR, 18.2% CR, 22.7% SD) compared to MSS (11.8% PR, 0% CR, 47% SD). MSI-H had higher ORR vs. MSS (54.1% vs 11.8%, p = 0.0078). CC trended toward improved ORR vs. MSS (44.4% vs 11.8%, p = 0.14). PFS was improved for MSI-H vs. MSS (10m v 5.0m, p = 0.03). OS for CC compared to any other histology was improved (NR vs 12.8m respectively, p = 0.009). 5 recurrent MSI-H EC patients received ICI as first line monotherapy. Responses included 4 PR and 1 SD (80% ORR, 100% clinical benefit). PFS was 9.2m (3.3-13.3). 80% remained progression-free at last follow up. Overall, 38.9% experienced toxicity: hypothyroidism (15%), dermatitis (5%), pneumonitis (10%), LFT elevation (2%), amylase/lipase elevation (3%), colitis or diarrhea (5%), uveitis (2%) or nephritis (5%). 10% of patients required discontinuation of ICI secondary to toxicity. Trends for PFS and OS favored improved outcomes in patients with toxicity vs. no toxicity [(PFS 12.9m vs 5.6m, p = 0.07), (OS 22.9m vs 13.1m, p = NS)] respectively. Conclusions: In this study, immunotherapy with ICI outcomes favor MSI-H and CC compared to MSS disease. CC had promising OS compared to other histology types. ICI showed promising efficacy in MSI-H EC with 100% clinical benefit rate in chemonaive patients. First line ICI should be investigated in these patients. Positive correlation between toxicity and outcome is noted and will be further investigated.
