e14577 Background: The management of grade 3/4 or steroid-refractory immune related adverse events (irAE) is based on a paucity of retrospective data analysis. Our initial experience with the combination therapy with Vincristine (VCR), immunoglobulin (IVIG) and glucocorticosteroid (VIG regimen) showed clinical improvement in a wide variety of irAEs. As a result, we recommend the use of VIG regimen for the management of grade 3/4 or steroid-refractory irAEs. Methods: The character and clinical course of irAEs were abstracted from the medical record and analyzed. The components of VIG regimens are as follows: Methylprednisolone (MP) 2-10mg/kg for 3days, VCR 1.4mg/m2 (≤2mg) continuous infusion for 4-8 hours on day 3 once a week with Immunoglobulin (IVIG) 0.4g/kg for 3-5 days. The dose of MP and IVIG will be reduced quickly after irAE improves. VCR 1.4mg/m2 once a week will be used for 1 to 3 times according to the improvement. Clinical improvement was defined as either: documentation of resolution of symptoms and normalisation of biochemical tests or hospital discharge within 14 days. Results: A total of 25 patients had grade3/4 or steroid-refractory irAEs after receiving immune checkpoint inhibitors and then received VIG regimen. Among them, 22 patients have been significantly improved, with an improvement rate of 88%. Twenty-three patents were treated in the inpatient setting (92%). The index grade 3/4 irAE was pneumonitis in 28%, immune mediated hepatotoxicity(IMH) in 28%, rash/SJS/TEN in 24%, cerebritis in 8 % and one case each of ITP, Near blindness and severe oral mucositis. In 7 patients with severe IMH, the range of total bilirubin was 80-481umol/L and ALT 35-5000u/L. Six patients with IMH recover well but one patient did not recover to normal due to IMH complicated with pneumonitis and TEN . Clinical improvement was noted in 22/25 patients (88%), 11 patients (44%) required a single dose, while 12 patients (48%) required two doses, 2 patients(8%) required three doses of VCR 1.4mg/m2 continuous infusion for 4-8 hours. What is impressive is that the two patients with encephalitis were significantly relieved within 2 weeks after using the VIG regimen. One patient with TEN (SCORETEN 3)was significantly improved and discharged from our hospital 11 days after using the VIG regimen. A patient with near-blind eyesight recovered to normal 3 days after using the VIG regimen. Conclusions: VIG regimen may be an effective therapeutic option for the management of grade3/4 or steroid-refractory irAEs secondary to immune checkpoint blockade. However, randomized trials are needed to better elucidate the efficacy and safety of VIG regimen.

e21712 Background: Immune checkpoint inhibitors are poised to revolutionize the management of a growing number of malignancies. Unfortunately, the management of steroid-refractory immune mediated adverse events (irAEs) is based on a paucity of randomized data and limited to single center experiences. Our initial experience with the IL-6 receptor antagonist tocilizumab showed clinical improvement in a wide variety of irAEs. As a result, we adopted the use of tocilizumab for the management of steroid-refractory irAEs. Methods:The character and clinical course of irAEs were abstracted from the medical record and analyzed. The dose of tocilizumab was 4 mg/kg given IV over 1 hour. C-reactive protein was drawn at first nivolumab infusion and at q 2 weeks (and with irAEs) thereafter. Clinical improvement was defined as either: documentation of resolution of symptoms or hospital d/c within 7 days. Results:Of the initial 87 patients that were treated with nivolumab, 34 required tocilizumab (39.1%). All pts were on corticosteroids. The majority (88.2%) were lung cancer patients. The index grade 3/4 irAE was pneumonitis in 35.3%, cytokine release syndrome/SIRS in 35.3%, cerebritis in 14.7% and one case each of hypophysitis, colitis, pancreatitis, hepatitis and immune mediated coagulopathy. Median time between first nivolumab and initiation of tocilizumab was 76 days (range 1-429). Median CRP at initial tocilizumab dose was 100.5 mg/L (2.0 -350.4). Clinical improvement was noted in 27/34 pts (79.4%). 52.9% of pts required a single dose, while 35.3% required two, 8.8% required three and 1 pt required 4 doses. Twenty seven doses were given in the inpatient setting (49.1%). Median time to discharge was 4 days (range 1-27). Seventy four percent of pts were discharged home. For the 55 doses of tocilizumab that were delivered there was a cost savings of $147,174.94 (WAC) during the 18 month period versus infliximab 5 mg/kg IV dose. Conclusions: Tocilizumab is a therapeutic option for the management of steroid refractory irAEs secondary to immune checkpoint blockade. However, randomized trials are needed to better elucidate the relative efficacy and safety of these agents.

As a result, we adopted the use of tocilizumab for the management of steroid refractory irAEs. Methods The character and clinical course of irAEs were abstracted from the medical record and analyzed. The dose of tocilizumab was 4 mg/kg given IV over one hour. C-reactive protein was drawn at first nivolumab infusion and at q two weeks (and with irAEs) thereafter. Clinical improvement was defined as either: documentation of resolution of symptoms or hospital discharge within seven days. Results Of the initial 87 patients that were treated with nivolumab, 34 required tocilizumab (39.1%). All patients were on corticosteroids. The majority (88.2%) were lung cancer patients. The index grade 3/4 irAE was pneumonitis in 35.3%, serum sickness/SIRS in 35.3%, cerebritis in 14.7% and one case each of hypophysitis, colitis, pancreatitis, hepatitis and immune mediated coagulopathy. Median time between first nivolumab and initiation of tocilizumab was 76 days (range 1–429). There was a statistically significant increase in C-reactive protein from a median of 23 mg/L (range 0.1–238.5) at baseline to 109.3 mg/L (21.5–350.4) at the time of index irAE, followed by a decrease to 19.2 mg/L (0.25–149) after tocilizumab ( p < 0.00001).

For the 53 doses of tocilizumab that were delivered when infliximab was an option, there was a cost savings of $141,048.72 (WAC) during the 18 month study period. Conclusions Tocilizumab may be a therapeutic option for the management of steroid refractory irAEs secondary to immune checkpoint blockade. However, randomized trials are needed to better elucidate the relative efficacy and safety of these agents.

Patients with extensive-stage small cell lung cancer (ED-SCLC) have a very short survival time even if they receive standard cytotoxic chemotherapy with etoposide and platinum (EP). Several randomized controlled trials have shown that patients with ED-SCLC who received a combination of EP plus immune checkpoint inhibitors (ICIs) had superior survival compared with those who received EP alone. We conducted a systematic review and network meta-analysis to provide a ranking of ICIs for our primary endpoints in terms of overall survival (OS), progression free survival (PFS), and objective response rate (ORR), as well as our secondary endpoint in terms of adverse events. The fractional polynomial model was used to evaluate the adjusted hazard ratios for the survival indicators (OS and PFS). Treatment rank was estimated using the surface under the cumulative ranking curve (SUCRA), as well as the probability of being best (Prbest) reference. EP plus nivolumab, atezolizumab or durvalumab had significant benefits compared with EP alone in terms of OS (Hazard Ratio HR = 0.67, 95% Confidence Interval CI = 0.46–0.98 for nivolumab, HR = 0.70, 95% CI = 0.54–0.91 for atezolizumab, HR = 0.73, 95% CI = 0.59–0.90 for durvalumab) but no significant differences were observed for pembrolizumab or ipilimumab. The probability of nivolumab being ranked first among all treatment arms was highest (SCURA = 78.7%, Prbest = 46.7%). All EP plus ICI combinations had a longer PFS compared with EP alone (HR = 0.65, 95% CI = 0.46–0.92 for nivolumab, HR = 0.77, 95% CI = 0.61–0.96 for atezolizumab, HR = 0.78, 95% CI = 0.65–0.94 for durvalumab, HR = 0.75, 95% CI = 0.61–0.92 for pembrolizumab), and nivolumab was ranked first in terms of PFS (SCURA = 85.0%, Prbest = 66.8%). In addition, nivolumab had the highest probability of grade 3–4 adverse events (SUCRA = 84.8%) in our study. We found that nivolumab had the best PFS and OS in all combinations of ICIs and EP, but nivolumab also had the highest probability of grade 3–4 adverse events in our network meta-analysis. Further head-to head large-scale phase III randomized controlled studies are needed to verify our conclusions.

Introduction: With the widespread use of immune checkpoint inhibitors (ICIs), we are facing challenges in the management of immune-related adverse events (irAEs). We aimed to characterize the spectrum of toxicity, management, and outcomes for irAEs. Methods: Patients who were treated with at least one ICI in clinical trials, expanded access programs, or routine clinical practice were included. Clinical and laboratory parameters were collected retrospectively to determine the incidence of irAEs, methods of management, and treatment outcomes. Results: A total of 255 patients were screened retrospectively. Of these, 71 (27.8%) patients developed irAEs. More than 2 different types of irAEs were detected in 16 (6.2%) out of 255 patients. A total of 3177 doses were given to 255 patients. In 93 (2.9%) of the 3177 doses, 1 episode of irAEs was experienced. A total of 22 out of 93 (23.7%) episodes were reported as grade 1, 49 (52.7%) as grade 2, 19 (20.4%) as grade 3, and 3 (3.2%) as grade 4. The most frequently seen irAEs were pneumonitis, hepatitis, and hypothyroidism. With regard to treatment, 39 out of 93 episodes (42%) of any grade irAEs occurred after anti–programmed cell death-1 therapy, 47 (50.5%) occurred following administration of anti–programmed death-ligand 1, and 7 (7.5%) occurred after combination treatments. Conclusion: With the increased use of immunotherapeutic agents, increased awareness and early recognition are required for effective management of irAEs. Our experience as a single institution might be of use for health care providers in oncology.

Background: This network meta-analysis assessed the comparative risk of grade 3–5 and grade 5 treatment-related adverse events (TRAEs) for immune checkpoint inhibitors (ICIs), either alone or in combination with other modalities, for cancer treatment. Methods: PubMed, Embase, Cochrane Library, Web of Science, and recent predominant oncology congresses were searched for relevant phase II and phase III randomized controlled trials (RCTs). As outcomes, grade 3–5, and grade 5 TRAE outcomes were reported as odds ratios and 95% confidence intervals. Results: In 67 RCTs involving 36,422 patients and 19 ICIs, the incidence of grade 3–5 and grade 5 TRAEs was 17.9% and 0.8% with ICI monotherapy and 46.3% and 1.4%, respectively, with combinatorial therapy. Pneumonitis was the most common cause of grade 5 TRAEs following either monotherapy (16.3%) or combinatorial therapy (11.4%). Regarding grade 3–5 TRAEs, atezolizumab + chemotherapy (CT) and antiangiogenic therapy (AT) (atezolizumab + CAT), pembrolizumab + CT, ipilimumab + CT, and atezolizumab + CT were more toxic than any ICI monotherapy, pembrolizumab or nivolumab + radiotherapy (RT), and ICIs dual therapy (durvalumab + tremelimumab and nivolumab + ipilimumab). Tremelimumab, ipilimumab, durvalumab, and pembrolizumab were, however, associated with higher grade 5 TRAEs than combinatorial treatments. Atezolizumab + CAT was the most toxic and nivolumab + RT was the least toxic of combinatorial treatments; among monotherapies, tremelimumab and avelumab were the most and least toxic, respectively. The toxicity ranking changed with type of grade 3–5 TRAEs. Conclusions: Compared with combinatorial therapy, ICI monotherapy caused lower grade 3–5 TRAEs, but some monotherapies resulted in a higher incidence of fatal TRAEs. Atezolizumab + CAT and nivolumab + RT were the most and least toxic of combinatorial treatments, respectively, and tremelimumab and avelumab were the most and least toxic of the monotherapies, respectively.

Background: Drug-induced colitis is a known complication of therapies that alter the immune balance, damage the intestinal barrier or disturb intestinal microbiota. Immune checkpoint inhibitors (ICI) directed against cancer cells may result in activated T lymphocyte-induced immune-related adverse events (AEs), including immune-related colitis and hepatitis. The aim of this review article is to summarize the incidence of gastrointestinal (GI) and hepatic AEs related to ICI therapy. We have also looked at the pathogenesis of immune-mediated AEs and propose management strategies based on current available evidence. Methods: A literature search using PubMed and Medline databases was undertaken using relevant search terms pertaining to names of individual drugs, mechanism of action, related AEs and their management. Results: ICI-related GI AEs are common, and colitis appears to be the most common side effect, with some studies reporting incidence as high as 30%. The incidence of both all-grade colitis and hepatitis were highest with combination therapy with anti-CTLA-4/PD-1; severity of colitis was dose-dependent (anti-CTLA-4). Early intervention is associated with better outcomes. Conclusion: ICI-related GI and hepatic AEs are common and clinicians need to be aware. Patients with GI AEs benefit from early diagnosis using endoscopy and computed tomography. Early intervention with oral steroids is effective in the majority of patients, and in steroid-refractory colitis infliximab and vedolizumab have been reported to be useful; mycophenolate has been used for steroid-refractory hepatitis.

341 Background: In patients with hepatocellular carcinoma (HCC) and baseline liver dysfunction, hepatic immune-related adverse events (HIRAEs) during immunotherapy have not been adequately characterized and their impact on subsequent treatment outcomes is not known. Methods: 40 patients with advanced/unresectable HCC and Child Pugh score A have been enrolled in first and second-line clinical trials of anti-programmed cell death protein 1 (PD-1) monoclonal antibodies (mAbs). HCC etiologies were: hepatitis C (32.5%), hepatitis B (7.5%), alcohol abuse (27.5%), other (32.5%). 7 received anti-PD-1 mAbs alone and 33 received combined regimens that included anti-PD-1 mAbs plus either anti-cytotoxic T lymphocyte antigen 4 (30.4%) or tyrosine kinase inhibitors (TKIs) (54.5%), or both (15.1%). We reviewed their liver function tests and HIRAEs onset was related to time to treatment failure (TTF). Results: Overall, 12 patients (30%) developed grade ≥ 3 hepatitis according to Common Toxicity Criteria for Adverse Events v. 4.03, resulting in 4 cases of grade 2 drug-induced liver injury per DILI Working Group criteria. Time between therapy initiation and hepatitis onset was 1.4 months (0.4-2.8) and median peak aminotransferase (AT) level was 258 IU/L (85-869). Out of 6 permanent treatment discontinuations due to adverse events (AEs), 4 were linked to hepatitis. Higher AT median levels at baseline were significantly linked to grade ≥ 3 hepatitis compared with lower grades (95 IU/L vs. 36 IU/L, respectively; p = 0.008). Etiology, age, treatment did not predict HIRAEs onset. TTF in patients in patients with grade ≥ 3 hepatitis was shorter than in the whole cohort (1.4 vs. 3.8 months, p = 0.041), while overall survival did not differ (p = 0.125). Conclusions: We observed a 30% incidence of clinically significant HIRAEs. HIRAEs represent the most frequent AEs leading to treatment discontinuation in patients with HCC undergoing treatments with immune checkpoint inhibitors. Baseline AT levels may identify patients at increased risk of grade ≥ 3 hepatitis.

e14525 Background: Immune checkpoint inhibitors (ICIs) have improved the survival of patients with multiple cancer types, however ICI treatment is associated with a unique set of immune-related adverse events (irAEs) that can affect any organ. Few studies have evaluated the risk factors and outcomes of ICI induced hepatitis (ICIH). Methods: We utilized an institutional database of patients with advanced cancers treated with ICI between 2011 and 2017 at The OSU Comprehensive Cancer Center to identify patients with ICIH. Any patient who received at least one dose of ICI alone or in combination with other systemic therapies either as part of clinical trial or standard of care were included. Clinical data were extracted through chart abstraction. irAEs were graded using the Common Terminology Criteria for Adverse Events v5. Overall survival (OS) was calculated from the date of ICI initiation to death from any cause or the date of the last follow-up. OS with 95% confidence intervals were estimated using the Kaplan–Meier method. OS was also evaluated by occurrence of ICIH using the log-rank test. Results: We identified 1,096 patients treated with at least one dose of ICI. Most common cancers included lung (n=224, 20%) and melanoma (n=342, 31%). The most common ICIs were PD1/L1 (n=774, 71%) and CTLA-4 inhibitors (n=195, 18%). ICIH of any grade occurred in 64 (6%) patients. Overall, 46 (71%) were male and median age was 60 years. Severity of hepatitis was grade 1-2 in 30 patients (47%) (Table 1). The incidence of ≥grade 3 ICIH in the entire cohort was 3.1%. Median time to ICIH diagnosis was 63 days. ICIH occurred alone in 24 patients, and co-occurred with other irAEs in 40 patients. The most common co-occurring irAEs were pneumonitis (n=7); colitis (n=15), thyroid abnormality (n=14); and dermatitis (n=15). ICIH was more common in women (p=0.038), in patients treated with combination ICIs (p<0.001), and among patients receiving first line therapy (p=0.018). Patients who developed ICIH had significantly longer OS than patients who did not develop ICIH; there was no difference in OS between patients with ≥grade 3 ICIH vs grade 1-2 (Table). 33 out of 34 patients with ≥grade3 ICIH were treated with steroids; 3 received mycophenolate and one received infliximab. Of patients with ≥grade 3 ICIH, 11 resumed ICI therapy without recurrent ICIH. Conclusions: Female sex, combination immunotherapy, and line of therapy were associated with ICIH. Patients with ICIH had improved clinical outcomes compared to those that did not develop ICIH, even those with higher grade toxicity. Further study is needed to assist in developing risk stratification models and optimal treatment for ICIH. OS of patients with and without immune checkpoint inhibitor hepatitis.[Table: see text]

e14580 Background: The use of immune-checkpoint inhibitors (ICIs) for solid malignancies is rapidly rising, and many new agents and treatment combinations are in development. However, ICIs have a unique side-effect profile of immune-related adverse events (irAEs) compared with chemotherapeutic agents or targeted therapies. The aim of this work was to describe the irAEs in diverse types of malignant tumors using real-world data. Methods: This is a retrospective and descriptive study of patients with diverse types of advanced malignancies treated with immunotherapy at Centro Oncológico Integral of the Hospital Ángeles in Puebla, México; during the period 2016-2020. Data about the primary neoplasm, ICIs, irAEs, organ system affected, grade and treatment was collected. Clinical and laboratory parameters were obtained by reviewing medical records. Results: A total of 117 patients were included, median age of 65 years, of which 63.2% were male and 36.8% were female. The most frequent neoplasms treated with ICIs were: lung (27.4%), kidney (16.2%), melanoma (12.8%), hepatocellular (9.4%), breast (8.5%), non-melanoma skin cancer (6.0%), mesothelioma (4.3%) and other tumors (15.3%). 39.3% of the patients had no metastases, 41.9% had metastases to at least 1 or 2 sites, and 18.8% to 3 or more sites. The types of ICIs were: nivolumab (35.0%), pembrolizumab (28.2%), atezolizumab (23.9%), ipilimumab + nivolumab (12.0%) and durvalumab (0.9%). The most frequent irAEs were: gastrointestinal (61.5%), neurologic (46.2%), pulmonary (38.5%), metabolic (32.5%) and hematologic (29.1%). 39.3% of the irAEs were reported as grade 1, 31.6% as grade 2, 14.5% as grade 3 and 2.6% as grade 4. Conclusions: Our work shows the incidence of irAEs in a poorly studied population and provides new data that complement that reported by other works, however, further prospective studies are necessary.[Table: see text]

Abstract Introduction: Approximately 75% of myelofibrosis (MF) patients develop anemia during evolution of the disease process predicting decreased survival. Previous studies exploring the effect of danazol in the treatment of anemia in MF demonstrate responses in anemia of 30-55%. Ruxolitinib has demonstrated improvement in MF related splenomegaly, symptom burden, and even survival yet improvements in cytopenias are uncommon. We designed a phase II multicenter pilot study to evaluate the efficacy and tolerability of combination therapy with ruxolitinib and danazol in MF patients with anemia. Methods: This is a pre-planned interim analysis of a Simon optimum two-stage phase II trial designed to include a minimum of 10 and a maximum of 27 patients. Participants received ruxolitinib 10mg (plat >75 x10x9) BID or 5mg (plat <75 x10 x9) BID with danazol 200mg orally TID. Dose escalation was allowed after completion of 28 days for lack of response or for disease progression. Patients without progression were continued for 6 cycles at 56 days each. Treatment modifications were based on adverse events including thrombocytopenia, leukopenia, and elevation in creatinine and transaminases. Treatment responses were evaluated by the IWG-MRT response criteria (Blood 2013). Patient reported outcome questionnaires (MPN-SAF and EORTC QLQ-C30) were administered at baseline, prior to treatment cycles, and at study discontinuation. Results: Patients: Ten of the 12 evaluable patients enrolled (median age 70.5, range 57-78, M:F ratio 4:1) are included in this analysis. Eight patients had primary MF (PMF), 1 had post essential thrombocytosis (ET) MF, and 1 had post polycythemia vera (PV) MF. Jak2 V617F mutation was positive in 30%. At the time of enrollment 40% had received an erythrocyte transfusion in the last month and all were DIPSS Int-2 or higher. Median baseline hemoglobin was 9.0 g/dL (range 8.3 - 12.4). Median baseline platelet level was 172 x10 (9)/L (range 56 - 346). Most (90%) had received prior therapy and many were refractory to multiple lines of therapy prior to enrollment. Three (30%) patients had previously participated in a JAK inhibitor clinical trial. Tolerability: Among 6 patients who have completed treatment, median duration of treatment was 39 days (range 24-287) with treatment discontinuation due to progression of disease in 2 patients, allogeneic stem cell transplant in 1, alternative treatment in 1, unrelated adverse event (hyponatremia) in 1, and unrelated death (leukemic transformation with intracranial hemorrhage) in 1. Hematologic Grade 3 or > adverse events included anemia (60%), neutropenia (20%), and leukopenia (10%). Non-hematologic Grade 3 or > adverse events included electrolyte abnormalities (20%), edema (10%), infection (10%), and intracranial hemorrhage (10%). Efficacy: Treatment response per IWG-MRT response criteria included stable disease (SD) in 8/10 (80%), clinical improvement in 1/10 (10%), and progressive disease (PD) in 1 (10%). The median change in hemoglobin and platelet count from baseline was -0.05 g/dL (range -0.5 - 1.8) and 28.5 x10(9)/L (range -143 – 118) respectively, however 4/10 (40%) and 7/10 (70%) had improvement at some point during treatment in level of anemia and/or thrombocytopenia. The median follow-up time was 2 months (range 0.9-9.4). Among 6 patients with a baseline and at least one post-baseline MPN-SAF TSS, 2/6 (30%) of patients had at least a 10-point (clinically meaningful) improvement, with 1 of the 2 achieving the stricter 50% improvement from baseline. Responses might have been confounded due to impact of prior therapies. Conclusions: On interim analysis, ruxolitinib and danazol combination therapy demonstrates modest additional clinical benefit, however in a group of exceedingly high risk MF patients with significant anemia and prior single agent JAK inhibitor failures. Preliminary data suggests improvement in anemia and/or thrombocytopenia in some treated patients however only one clinical improvement per IWG-MRT criteria was observed. Combination therapy was well tolerated with no major incremental toxicity attributable to the addition of danazol. Maturation of data is needed to fully evaluate efficacy of ruxolitinib and danazol combination therapy prior to continuation of accrual.
