Objective: To investigate the role of CTLA-4, PD-1 (programmed death-1), and PD-L1 (programmed death-ligand 1) single nucleotide polymorphisms (SNPs) in predicting clinical outcome of patients with advanced non-small cell lung cancer (NSCLC) treated with immune checkpoint inhibitors (ICIs). Methods: A total of 166 consecutive patients were included. We correlated SNPs with clinical benefit, progression-free survival, time to treatment failure, and overall survival and evaluated the incidence of SNPs in nonresponder and long clinical benefit groups. Results: Considering the entire cohort, no correlation was found between SNPs and clinical outcome; however, PD-L1 rs4143815 SNP and the long clinical benefit group showed a statistically significant association ( p = 0.02). The nonresponder cohort displayed distinctive PD-L1 haplotype ( p = 0.05). Conclusion: PD-L1 SNPs seem to be marginally involved in predicting clinical outcome of NSCLC treated with ICI, but further investigations are required.

The immune system has long been known to play a critical role in the body’s defence against cancer, and there have been multiple attempts to harness it for therapeutic gain. Renal cancer was, historically, one of a small number of tumour types where immune manipulation had been shown to be effective. The current generation of immune checkpoint inhibitors are rapidly entering into routine clinical practice in the management of a number of tumour types, including renal cancer, where one drug, nivolumab, an anti-programmed death-1 (PD-1) monoclonal antibody (mAb), is licensed for patients who have progressed on prior systemic treatment. Ongoing trials aim to maximize the benefits that can be gained from this new class of drug by exploring optimal timing in the natural course of the disease as well as combinations with other checkpoint inhibitors and drugs from different classes.

e14162 Background: It is well established that an altered host metabolism has an impact on cancer outcome, possibly mediated by several mechanisms, including hyperglicaemia, hyperinsulinemia and presence of chronic inflammation. The aim of our analysis was to evaluate the correlation between host metabolism and clinical outcome in patients with advanced melanoma, kidney and non-small cell lung cancer (NSCLC), treated with immune checkpoint inhibitors (anti-CTLA4, anti PD1 and anti PDL1). Methods: The relationship between presence of type 2 diabetes mellitus (DMII) at baseline and outcome was assessed in 187 patients treated with immune checkpoint inhibitors in two cancer centers. Progression Free Survival (PFS) and Overall Survival (OS) were calculated by Kaplan-Meier estimation; multivariate Cox analysis was performed according to age, gender, BMI (normal < 25 kg/m2, overweight 25-30 kg/m2, obese > 30 kg/m2), type of cancer and line of treatment. Results: One-hundred-sixty-eight patients were available for our analysis. Twenty-eight patients (17%) were diabetic at baseline. Median age was 65 (range 25-80); 83 patients were males (49%); 82 (48%) had advanced melanoma, 83 (49%) NSCLC and 3 (3%) kidney cancer. One-hundred-two (60%) patients had BMI < 25, 51 (30%) were overweight and 16 (10%) were obese. The first line of treatment was immunotherapy in 83 (49%) patients. By univariable analysis median PFS was 4.2 months in non diabetics vs 6.4 in diabetics patients (HR 0.95; 95%CI 0.58-1.58); median OS was 6.17 and 9.1 months, respectively (HR 1.00; 95%CI 0.58-1.75). At multivariable analysis, taking into account DMII, BMI, sex, age, line of treatment and type of cancer, we found that BMI ≤25 was associated with a two fold increase in risk of progression (PD) or death (p = 0.005), whereas patients who received immunotherapy as second or subsequent line had a two fold increase in risk of PD or death (p = 0.003). Conclusions: The results of our analysis show that in patients with advanced cancer treated with immune checkpoint inhibitors, the presence of DMII does not adversely affect the clinical outcome. Conversely, lower BMI was associated with a significantly worse PFS and OS, independently from type of cancer, age and gender. As expected, patients who received immunotherapy in later lines of treatment had a significantly shorter survival.

Immune-checkpoint inhibitors blocking the programmed death 1/programmed death-ligand 1 (PD-1/PD-L1) and cytotoxic T-lymphocyteassociated protein 4 (CTLA-4) have shown a prominent anti-tumor activity with long-term responses and an acceptable toxicity profile  in clinical trials. Pembrolizumab, atezolizumab, nivolumab, avelumab, and durvalumab are anti-PD-1/PD-L1 agents that redefine the standard of care for advanced urothelial carcinoma. CTLA-4 inhibitors are also under investigation in this setting. Phase III trial KEYNOTE-045 has demonstrated significant survival benefit in patients treated with pembrolizumab comparing with the standard second-line chemotherapy. Atezolizumab, nivolumab, avelumab, and durvalumab were also recommended for platinum-pretreated urothelial carcinoma patients based on phase II data. Following investigations of biomarkers such as PD-L1 expression are needed to determine high-responders to immunotherapy. This review article describes the advances in immunotherapy with immune-checkpoint inhibitors.

Introduction Immune agents including anti-programmed death receptor-1 and anti-cytotoxic T-lymphocyte antigen-4 have been associated with numerous immune-related complications. Pembrolizumab, a programmed death-1 inhibitor, has been associated with a number of immune-related adverse events such as pneumonitis, colitis, hepatitis, hypophysitis, hyperthyroidism, hypothyroidism, nephritis, and type 1 diabetes. Case report We present a rare case of an elderly male on pembrolizumab who suffered from four autoimmune toxicities including type 1 diabetes, pneumonitis, hypothyroidism, and polymyalgia rheumatica likely catalyzed by age-related immune activation. Management and outcome: Immunotherapy was indefinitely stopped, and patient was started on steroids for the immune-related adverse events with complete resolution of polymyalgia rheumatica. Thyroid dysfunction resolved once he started thyroid replacement therapy. His diabetes is well controlled with insulin and is followed by endocrinology. He continues on prednisone for immune-mediated pneumonitis with a good response with regular monitoring via computed tomography scans and pulmonary consultation. Discussion Few cases wherein multiple toxicities are seen within one patient are reported. Aging appears to be a risk factor for immune-related adverse events. Aging is associated with an increased incidence of autoimmunity as programmed death-1 ligand expression represents an important mechanism that tissues use to protect from self-reactive effector T cells. Programmed death-1 blockade breaks this protective mechanism and enhances autoimmune diseases. Therefore, close monitoring and extreme vigilance is warranted while using immune checkpoint inhibitors including pembrolizumab as multiple toxicities can occur within a short span of infusion, especially in elderly individuals. Prompt discontinuation and the use of a multidisciplinary team are prudent to prevent further morbidity and mortality.

Immune checkpoint inhibitors (ICIs), especially those targeting the programmed-death 1 (PD-1) receptor and its ligands, have become indispensable agents in solid tumor anti-cancer therapy. Concerning hematological malignancies, only nivolumab and pembrolizumab have been approved for the treatment of relapsed and refractory classical Hodgkin lymphoma and primary mediastinal large B cell lymphoma to date. Nevertheless, clinical research in this field is very active. The mechanism of action of ICIs is based on unblocking the hindered immune system to recognize and eliminate cancer cells, but that also has its costs in the form of ICI-specific immune related adverse events (irAEs), which can affect any organ system and can even be lethal. In this article, we have reviewed all prospective blood cancer clinical trials investigating ICIs (both monotherapy and combination therapy) with available toxicity data with the purpose of determining the incidence of irAEs in this specific setting and to offer a brief insight into their management, as the use of immune checkpoint blockade is not so frequent in hemato-oncology.

Abstract Background Recent studies have shown that immune-related adverse events (irAEs) caused by immune checkpoint inhibitors were associated with clinical benefit in patients with melanoma or lung cancer. In advanced gastric cancer (AGC) patients, there have been few reports about the correlation between irAEs and efficacy of immune checkpoint inhibitors. In this study, we retrospectively investigated the correlation between irAEs and efficacy in AGC patients treated with nivolumab. Methods The subjects of this study were AGC patients received nivolumab monotherapy between January 2015 and August 2018. IrAEs were defined as those AEs having a potential immunological basis that required close follow-up, or immunosuppressive therapy and/or endocrine therapy. We divided the patients who received nivolumab into two groups based on occurrence of irAEs; those with irAEs (irAE group) or those without (non-irAE group). We assessed the efficacy in both groups. Results Of the 65 AGC patients that received nivolumab monotherapy, 14 developed irAEs. The median time to onset of irAEs was 30.5 days (range 3–407 days). Median follow-up period for survivors was 32 months (95% CI, 10.8 to 34.5). The median progression-free survival was 7.5 months (95% CI, 3.6 to 11.5) in the irAE group and 1.4 months (95% CI, 1.2 to 1.6) in the non-irAE group (HR = 0.11, p < 0.001). The median overall survival was 16.8 months (95% CI, 4.4 to not reached) in the irAE group and 3.2 months (95% CI, 2.2 to 4.1) in the non-irAE group (HR = 0.17, p < 0.001). Multivariate analysis demonstrated that number of metastatic sites ≥2 (HR = 2.15; 95% CI, 1.02 to 4.54), high ALP level (HR = 2.50; 95% CI, 1.27 to 4.54), and absence of irAEs (HR = 9.54, 95% CI, 3.34 to 27.30 for yes vs. no) were associated with a poor prognosis. The most frequent irAEs was diarrhea/colitis (n = 5). Grade 3 adverse events were observed in 6 patients; hyperglycemia (n = 2), diarrhea/colitis (n = 1), adrenal insufficiency (n = 1), aspartate aminotransferase increased (n = 1), peripheral motor neuropathy (n = 1). There were no grade 4 or 5 adverse events related to nivolumab. Conclusions Development of irAEs was associated with clinical benefit for AGC patients receiving nivolumab monotherapy.

Immune checkpoint inhibitors targeting cytotoxic T-lymphocyte-associated protein-4 (CTLA-4) and programmed death-1 (PD-1)/ligand are increasingly used to treat several types of cancer. These drugs enhance antitumour T-cell activity and therefore induce immune-related adverse effects (irAE), of which gastrointestinal (GI) irAE are among the most frequent and severe. This systematic literature review summarises the clinical manifestations, management and pathophysiology of GI irAE due to immune checkpoint inhibitors. GI irAE induced by anti-CTLA-4 are frequent, potentially severe and resemble IBD, whereas those induced by PD-1 blockade seem to be less frequent and clinically more diverse. Baseline symbiotic gut microbiota is associated with an enhanced antitumour response to immune checkpoint inhibitors and an increased susceptibility to developing enterocolitis, in patients treated with anti-CTLA-4. These findings open new perspectives for possible manipulation of the gut microbiota in order to better identify responders to immune checkpoint inhibitors and to increase their efficacy and safety.
