Abstract
INTRODUCTION The treatment of melanoma is evolving rapidly over the past few years. Patients with BRAFv600 mutations can be treated with a combination of a BRAF-inhibitor and an MEK-inhibitor. Patients with BRAF wild-type tumors and BRAFv600 mutated tumors can be treated with immunotherapy i.e. check point inhibitors. AREAS COVERED We conducted a comprehensive review of the literature on the efficacy and predictive markers, safety, and pharmacoeconomics of ipilimumab in melanoma Expert commentary: Ipilimumab was the first check point inhibitor reaching the clinic, gaining FDA and EMA approval for metastatic melanoma in 2011. Ipilimumab was also approved by FDA in the adjuvant setting for patients with high risk, stage III melanoma. The anti-PD1 directed antibodies pembrolizumab and nivolumab are superior to single agent ipilimumab, which is no longer considered the standard first line treatment in metastatic melanoma. The addition ipilimumab to nivolumab is associated with a higher response rate and a better PFS, particularly in patients with PD-L1 negative tumors, albeit at the cost of a steep increase in grade 3-4 adverse event rate. Definitive survival data on this combination are pending and the selection of patients potentially requiring the combination and its pharmacoeconomic implications are to be elucidated.

Abstract
Ipilimumab is used for the treatment of metastatic melanoma and is associated with serious immune-related colitis. We aimed to report the clinical features, treatment, and outcomes of patients with ipilimumab-induced colitis. In this retrospective observational study, we identified patients with unresectable melanoma treated with ipilimumab between March 2011 and September 2013. Diarrhea was assessed using the Common Terminology Criteria for Adverse Events, v3.0. Colitis was defined by diarrhea (grade≥2) requiring steroids with or without endoscopic/histologic/radiologic evidence of colitis. A total of 103 patients with metastatic melanoma treated with ipilimumab were identified. Of these, 30 patients (29%) developed diarrhea (all grades), and 23 patients (22%) developed colitis requiring systemic corticosteroid therapy. The median number of ipilimumab doses before onset of diarrhea was 2 (range, 1-4). Six of 23 patients responded to less than 1 mg/kg daily prednisone alone. Fifteen patients required high-dose oral and/or intravenous prednisone (1-2 mg/kg body weight). Six patients had diarrhea refractory to prednisone; five required rescue therapy with budesonide (9-12 mg daily) and one was treated with infliximab (5 mg/kg, three doses). There was one case of severe diarrhea (grade 3) treated successfully with high-dose budesonide (12 mg) monotherapy. Ipilimumab-induced colitis requires early and aggressive medical therapy. Most patients can be successfully managed with systemic corticosteroids. High-dose budesonide is an attractive steroid-sparing agent, however further studies of its efficacy in this setting are needed. Infliximab should be used in refractory cases to avoid colectomy.

Abstract
Drug-induced interstitial nephritis is a recognized cause of acute and chronic renal failure. Some of them lead to the formation of granulomata. T-cell-mediated immune response is implicated in the pathogenesis. Here, we describe the case of a 74-year-old male patient with metastatic melanoma who was referred to our clinic with a history of rash and worsening renal function. Because of subacute onset, progressively worsening renal function in the presence of skin rash, elevated liver enzymes, and in the background of exposure, medication-induced interstitial nephritis was suspected. He received 3 doses of ipilimumab, a novel drug used in the treatment of metastatic melanoma within 3 months before the onset of renal failure. A renal biopsy was done, which showed granulomatous interstitial nephritis. Renal biopsy findings, temporal relation between renal failure and exposure to medication, and review of the literature supported a diagnosis of ipilimumab-induced renal failure. He was started on steroids, and renal function recovered in the next 1 month. Immune-related adverse reaction is one of the common side effects of ipilimumab. Ipilimumab-induced hepatitis and colitis has been previously reported in the literature. This is the first ever case report of ipilimumab-induced granulomatous interstitial nephritis.

Abstract
Background Ipilimumab improves survival in metastatic melanoma patients. This population frequently develops brain metastases, which have been associated with poor survival and are often treated with radiation. Therefore, outcomes following ipilimumab and radiation are of interest, especially given case reports and animal studies suggest combined treatment may generate abscopal responses outside the radiation field. Findings We reviewed sixteen consecutive melanoma patients who received 1 to 8 courses of radiation, with a sum total of 51, systematically evaluating abscopal responses by following the largest extra-cranial lesion. We also reviewed other series of patients treated with cranial radiation and ipilimumab. Our patients received between 1 and 8 courses of cranial radiation. Four patients received radiation concurrently with ipilimumab. Median survival was 14 months, and 17 months in patients initially treated with SRS. Interestingly, after radiotherapy, there was a 2.8-fold increased likelihood that the rate of extra-cranial index lesion response improved that didn’t reach statistical significance (p = 0.07); this was more pronounced when ipilimumab was administered within three months of radiation (p < 0.01). Conclusion Our experience and review of recently published series suggest ipilimumab and cranial radiation is well tolerated and can result in prolonged survival. Timing of ipilimumab administration in relation to radiation may impact outcomes. Additionally, our results demonstrate a trend for favorable systemic response following radiotherapy worthy of further evaluation in studies powered to detect potential synergies between radiation and immunotherapy.

Abstract
OBJECT In patients with large or symptomatic brain lesions from metastatic melanoma, the value of resection of metastases to facilitate administration of systemic ipilimumab therapy has not yet been described. The authors undertook this study to investigate whether craniotomy creates the opportunity for patients to receive and benefit from ipilimumab who would otherwise succumb to brain metastasis prior to the onset of regression. METHODS All patients with metastatic melanoma who received ipilimumab and underwent craniotomy for metastasis resection between 2008 and 2014 at the Massachusetts General Hospital were identified through retrospective chart review. The final analysis included cases involving patients who underwent craniotomy within 3 months prior to initiation of therapy or up to 6 months after cessation of ipilimumab administration. RESULTS Twelve patients met the inclusion criteria based on timing of therapy (median age 59.2). The median number of metastases at the time of craniotomy was 2. The median number of ipilimumab doses received was 4. Eleven of 12 courses of ipilimumab were stopped for disease progression, and 1 was stopped for treatment-induced colitis. Eight of 12 patients had improvement in their performance status following craniotomy. Of the 6 patients requiring corticosteroids prior to craniotomy, 3 tolerated corticosteroid dose reduction after surgery. Ten of 12 patients had died by the time of data collection, with 1 patient lost to follow-up. The median survival after the start of ipilimumab treatment was 7 months. CONCLUSIONS In this series, patients who underwent resection of brain metastases in temporal proximity to receiving ipilimumab had qualitatively improved performance status following surgery in most cases. Surgery facilitated corticosteroid reduction in select patients. Larger analyses are required to better understand possible synergies between craniotomy for melanoma metastases and ipilimumab treatment.

Abstract
BACKGROUND Targeting CTLA-4 is a recent strategic approach in cancer control: blocking CTLA-4 enhances an antitumor immunity by promoting T-cell activation and cytotoxic T-lymphocyte proliferation. This induction of a tolerance break against the tumor may be responsible for immune-related adverse events (irAEs). Our objective was to assess the incidence and nature of irAEs in oncologic patients receiving anti-CTLA-4 antibodies (ipilimumab and tremelimumab). METHODS A systematic search of literature up to February 2014 was performed in MEDLINE, EMBASE, and Cochrane databases to identify relevant articles. Paired reviewers independently selected articles for inclusion and extracted data. Pooled incidence was calculated using R(©), package meta. RESULTS Overall, 81 articles were included in the study, with a total of 1265 patients from 22 clinical trials included in the meta-analysis. Described irAEs consisted of skin lesions (rash, pruritus, and vitiligo), colitis, and less frequently hepatitis, hypophysitis, thyroiditis, and some rare events such as sarcoidosis, uveitis, Guillain-Barré syndrome, immune-mediated cytopenia and polymyalgia rheumatic/Horton. The overall incidence of all-grade irAEs was 72 % (95 % CI, 65-79 %). The overall incidence of high-grade irAEs was 24 % (95 % CI, 18-30 %). The risk of developing irAEs was dependent of dosage, with incidence of all-grade irAEs being evaluated to 61 % (95 % CI, 56-66 %) for ipilimumab 3 mg/kg and 79 % (95 % CI, 69-89 %) for ipilimumab 10 mg/kg. Death due to irAEs occurred in 0.86 % of patients. The median time of onset of irAEs was about 10 weeks (IQR, 6-12) after the onset of treatment, corresponding with the first three cycles but varied according to the organ system involved. Such immune activation could also be indicative for tumor-specific T-cell activation and irAE occurrence was associated with clinical response to CTLA-4 blocking in 60 % of patients. CONCLUSION The price of potential long-term survival to metastatic tumors is an atypical immune toxicity, reflecting the mechanism of action of anti-CTLA-4 antibodies. A better knowledge of these irAEs and its management in a multidisciplinary approach will help to reduce morbidity and therapy interruptions.

Abstract
Advances in the understanding of the immunogenicity of tumors have provided the basis for immuno-oncology, the development of immunotherapeutic agents that augment the patient's antitumor immunity and disrupt the immune-regulatory circuits that allow tumors to evade the immune system. Two immunomodulatory agents recently have been introduced for the treatment of malignancy: sipuleucel-T and ipilimumab. Unlike cytotoxic chemotherapy, immunotherapies stimulate the patient's immune system to mount or augment existing endogenous antitumor immune responses. Both agents have demonstrated significant improvements in long-term overall survival in patients. Like other immunotherapies, sipuleucel-T and ipilimumab also are characterized by adverse events that manifest as immune-related inflammatory conditions that typically are low grade. Management guidelines have been developed and emphasize early recognition of the signs and symptoms of immune-related adverse events and treatment with corticosteroids. Because these events can manifest even after the cessation of therapy, patients treated with immunotherapies should continue to be followed by their oncology team and other healthcare providers.

Abstract
Ipilimumab has been shown to improve overall survival in patients with advanced melanoma. Ipilimumab acts through immune-modulation, and is recognized to cause potentially severe immune-related adverse events (irAEs) including dermatitis, colitis, thyroiditis, hypophysitis, and hepatitis. The acceptance of ipilimumab as a treatment for metastatic melanoma means patients will continue to be treated with this agent and gastroenterologists will be increasingly called upon to assist in managing severe autoimmune-related hepatitis and colitis. To date, the recommendations for managing irAEs secondary to ipilimumab have been steroids at a moderate dose of prednisolone (1 mg/kg) as well as immunosuppressive agents such as mycophenolate mofetil (MMF) for steroid-refractory hepatitis and infliximab in the management of corticosteroid-refractory colitis. However, the dosing and the duration of immunosuppressive therapy have not been systematically studied in the setting of treating ipilimumab-induced irAEs. Therefore, additional immune-modifying agents and/or a change in dosing may be required to manage severe irAEs unresponsive to existing treatment recommendations. We describe a treatment paradigm illustrated by a series of five patients who experienced irAEs. In three cases of metastatic melanoma, ipilimumab-induced hepatitis was successfully treated with high-dose parenteral pulsed methylprednisolone. In two other melanoma patients with ipilimumab-induced colitis, one patient had satisfactory resolution of his colitis with high-dose corticosteroid therapy alone and the other patient required infliximab infusion. We have reviewed the current literature and management algorithms for ipilimumab-induced irAEs. Treatment options and the rationale for their use are discussed, including the use of pulsed high-dose steroids, MMF, azathioprine and calcineurin inhibitors.

Abstract
New insight on the interaction between the immune system and tumor has identified the programmed death-1/programmed death-1 ligand pathway to be a key player in evading host immune response. The immune checkpoint modulator, nivolumab (BMS-936558/ONO-4538), is the first PD-1 inhibitor to gain regulatory approval, for the treatment of patients with unresectable melanoma. This review will discuss results from early phase studies of nivolumab in solid tumors including non-small cell lung cancer (NSCLC) as well as studies of nivolumab in combination with chemotherapy, other immune modulators and molecular targeted therapy in patients with NSCLC.

Abstract
Ipilimumab, a novel therapy for metastatic melanoma, inhibits cytotoxic T-lymphocyte apoptosis, causing both antitumor activity and significant autoimmunity, including autoimmune thyroiditis. Steroids are frequently used in treatment of immune-related adverse events; however, a concern regarding the property of steroids to reduce therapeutic antitumor response exists. This study describes the first reported case of ipilimumab-associated thyroid storm and implicates iopanoic acid as an alternative therapy for immune-mediated adverse effects. An 88-year-old woman with metastatic melanoma presented with fatigue, anorexia, decreased functional status, and intermittent diarrhea for several months, shortly after initiation of ipilimumab – a recombinant human monoclonal antibody to the cytotoxic T-lymphocyte-associated antigen 4 (CTLA4). On arrival, she was febrile, tachycardic, and hypertensive with a wide pulse pressure, yet non-toxic appearing. She had diffuse, non-tender thyromegaly. An electrocardiogram (EKG) revealed supraventricular tachycardia. Blood, urine, and stool cultures were collected, and empiric antibiotics were started. A computed tomography (CT) angiogram of the chest was negative for pulmonary embolism or pneumonia, but confirmed a diffusely enlarged thyroid gland, which prompted thyroid function testing. TSH was decreased at 0.16 μIU/ml (normal 0.3–4.7); free tri-iodothyronine (T3) was markedly elevated at 1031 pg/dl (normal 249–405), as was free thyroxine (T4) at 5.6 ng/dl (normal 0.8–1.6). With iopanoic acid and methimazole therapy, she markedly improved within 48 h, which could be attributed to lowering of serum T3 with iopanoic acid rather than to any effect of the methimazole. Ipilimumab is a cause of overt thyrotoxicosis and its immune-mediated adverse effects can be treated with iopanoic acid, a potent inhibitor of T4-to-T3 conversion.

Abstract
Monoclonal antibodies directed against the immune checkpoint protein cytotoxic T-lymphocyte antigen-4 (CTLA-4; CD152) have been investigated in metastatic melanoma and other cancers and have shown promising results. Inhibition of CTLA-4 characteristically induces well-known side effects called "immune-related adverse events" (irAEs). IrAEs mainly include colitis, dermatitis, hepatitis, endocrinopathies; uveitis, iridocyclitis, neuropathies, and inflammatory myopathy have occasionally been reported. Kidney involvement is rare. We report 2 cases of acute granulomatous interstitial nephritis and present, based on literature review, renal disorders related to Ipilimumab therapy. Autoimmune symptoms have to be carefully checked for patients treated with CTLA-4 inhibitors. In order to reduce the risk of sequelae, early recognition of irAEs and treatment initiation are crucial.

Abstract
OBJECTIVE To report a case of ipilimumab-associated life-threatening diarrhea responding quickly to a single dose of infliximab. CASE SUMMARY A 67-year-old man presented 3 weeks after his second dose of ipilimumab with severe diarrhea, acute kidney injury, and hypotension. After 2 days of high-dose corticosteroids and supportive care, he continued to have 2.8 L of stool output per day (grade 4 National Cancer Institute Common Terminology Criteria for Adverse Events). The patient was transferred to the medical intensive care unit requiring endotracheal intubation because of concerns of worsening mental status, metabolic acidosis, and increased work of breathing, with a serum bicarbonate concentration of <5 mmol/L. Despite aggressive fluid resuscitation and a sodium bicarbonate infusion, he remained hypotensive and hyponatremic with persistent premature ventricular contractions. On the evening of day 3, infliximab (5 mg/kg) was given, resulting in a rapid decrease in diarrhea. After 48 hours, the acidosis was corrected and electrolytes, renal function, and fluid status were improving. At discharge, diarrhea, acute kidney injury, and acidosis had resolved, and he was discharged on a slow steroid taper. DISCUSSION Autoimmune colitis is a described immune-related adverse event of ipilimumab. Prompt recognition, initiation of steroids, and supportive therapy are key to the management of diarrhea. Infliximab should be considered early in steroid-nonresponsive or life-threatening diarrhea. CONCLUSION Infliximab is a life-saving intervention in patients with ipilimumab-induced diarrhea.

Abstract
BACKGROUND In a phase III trial (ClinicalTrials.gov registration ID: NCT00094653), ipilimumab significantly improved survival versus a vaccine control in pretreated patients with metastatic melanoma. Here, we characterize outcomes of those patients who survived ≥ 2 years. METHODS Patients were randomized (3 : 1 : 1) to receive ipilimumab 3 mg/kg + gp100 vaccine, ipilimumab 3 mg/kg + placebo, or gp100 vaccine alone. Baseline demographic data, duration of survival, responses, and safety among patients with ≥ 2 years' survival were analyzed. RESULTS Among 676 randomized patients, 474 and 259 patients had at least 2 or 3 years of potential follow-up, respectively, and were eligible for analysis. Among these, 94 (20%) and 42 (16%) survived ≥ 2 and ≥ 3 years, respectively. Survival rates at 2 and 3 years were 25% (24 of 95) and 25% (13 of 53) with ipilimumab alone and 19% (54 of 284) and 15% (24 of 156) with ipilimumab plus gp100. Safety among patients with ≥ 2 years' survival was comparable with the overall study population, with the onset of new ipilimumab-related toxic effect (all grades) reported in 6 of 78 (8%) patients. CONCLUSIONS Ipilimumab results in survival of ≥ 2 years in one-fifth of pretreated patients with 2 years potential follow-up in a phase III trial. New onset, low-grade events starting after administration of the last dose were infrequent. TRIAL REGISTRATION ID NCT00094653.

Abstract
Cancers must evade or suppress the immune system in order to develop. Better understanding of the molecular regulation governing tumour detection and effective activation of the immune system (so called immune regulatory checkpoints) has provided new targets for cancer immunotherapy. Therapeutic monoclonal antibodies against these targets are currently undergoing clinical evaluation with more in pre-clinical development; buoyed by the recent licence approval of the anti-CTLA-4 antibody, ipilumumab, for use in melanoma. This article will review the current status of the various antibodies and target molecules being investigated.

Abstract
The treatment for metastatic melanoma has evolved significantly in the past few years. Ipilimumab, an immunotherapy, is now in mainstream oncology practice given that it has shown improved overall survival in randomized clinical trials. Other immune modulating agents, such as programmed death receptor-1 and programmed death receptor ligand-1 antibodies, are showing promise in early clinical trials. This manuscript will review ipilimumab and its most common side effects. Immune-related adverse events (irAEs) are important to recognize early, and their presentation, timing of onset, and general recommendations for workup and management will be reviewed. Assembling a multidisciplinary team, as well as thorough education of the patient, is recommended to optimize patient care.

Abstract
BACKGROUND This analysis was carried out to evaluate the long-term survival of patients with metastatic melanoma who received ipilimumab, a fully human monoclonal antibody that binds to cytotoxic T-lymphocyte antigen-4, in clinical trials. PATIENTS AND METHODS Patients received ipilimumab in one of three completed phase II clinical trials (CA184-008, CA184-022, and CA184-007). Previously treated patients were enrolled in all studies, and treatment-naïve patients were also included in study CA184-007. Patients received ipilimumab at a dose of 10 mg/kg in studies CA184-008 and CA184-007, and at doses of 0.3, 3, or 10 mg/kg in study CA184-022. Ipilimumab was given every 3 weeks for four doses, and eligible patients could receive ipilimumab maintenance therapy every 12 weeks. In study CA184-022, patients could cross over to be retreated with ipilimumab at 10 mg/kg upon disease progression. Ongoing survival follow-up is conducted in a companion study, CA184-025. RESULTS Four-year survival rates [95% confidence interval (95% CI)] for previously treated patients who received ipilimumab at 0.3, 3, or 10 mg/kg were 13.8% [6.1-22.5], 18.2% [9.5-27.6], and 19.7% [13.4-26.5] to 28.4% [13.9-44.2], respectively. In treatment-naïve patients who received ipilimumab at 10 mg/kg, 4-year survival rates were 37.7% [18.6-57.4] to 49.5% [23.8-75.4]. CONCLUSIONS These results demonstrate durable survival in a significant proportion of patients with metastatic melanoma who received ipilimumab therapy.

Abstract
Ipilimumab, a fully human anti-cytotoxic T-lymphocyte antigen-4 monoclonal antibody that potentiates antitumor T-cell responses, has demonstrated improved survival in previously treated and treatment-naïve patients with unresectable stage III/IV melanoma. Survival benefit has also been shown in diverse patient populations, including those with brain metastases. In 2011, ipilimumab (3 mg/kg every 3 weeks for 4 doses) was approved by the Food and Drug Administration for unresectable or metastatic melanoma. Ipilimumab can induce novel response patterns for which immune-related response criteria have been proposed. irAEs are common but are usually low grade; higher grades can be severe and life-threatening. irAEs are usually manageable using established guidelines emphasizing vigilance and prompt intervention. This agent provides an additional therapeutic option in metastatic melanoma, and guidelines for management of adverse events facilitate clinical implementation of this new agent.

Abstract
Immunomodulation with the anti-CTLA-4 monoclonal antibody ipilimumab has been shown to extend overall survival (OS) in previously treated and treatment-naive patients with unresectable stage III or IV melanoma. Blockade of CTLA-4 signaling with ipilimumab prolongs T-cell activation and restores T-cell proliferation, thus amplifying T-cell-mediated immunity and the patient's capacity to mount an effective antitumor immune response. While this immunostimulation has unprecedented OS benefits in the melanoma setting, it can also result in immune-mediated effects on various organ systems, leading to immune-related adverse events (irAEs). Ipilimumab-associated irAEs are common and typically low grade and manageable, but can also be serious and life threatening. The skin and gastrointestinal tract are most frequently affected, while hepatic, endocrine, and neurologic events are less common. With proper management, most irAEs resolve within a relatively short time, with a predictable resolution pattern. Prompt and appropriate management of these irAEs is essential and treatment guidelines have been developed to assist oncologists and their teams. Implementation of these irAE management algorithms will help ensure that patients are able to benefit from ipilimumab therapy with adequate control of toxicities.

Patterns of onset and resolution of immune-related adverse events of special interest with ipilimumab: detailed safety analysis from a phase 3 trial in patients with advanced melanoma. Cancer 2013; 119:1675-82. [PMID: 23400564 DOI: 10.1002/cncr.27969] [Citation(s) in RCA: 337] [Impact Index Per Article: 30.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2012] [Revised: 12/19/2012] [Accepted: 12/26/2012] [Indexed: 12/13/2022]
Abstract
BACKGROUND Ipilimumab 3 mg/kg was the first agent to demonstrate improved survival in previously treated patients with metastatic melanoma in a phase 3 trial (MDX010-20). Ipilimumab produced a characteristic spectrum of immune-related adverse events (irAEs) of special interest, consistent with its immune-based mechanism of action. METHODS In MDX010-20, 676 previously treated patients were randomized 3:1:1 to receive ipilimumab 3 mg/kg plus the glycoprotein 100 melanoma antigen vaccine (gp100), ipilimumab 3 mg/kg + placebo, or gp100 vaccine + placebo. For the current report, the authors conducted a detailed analysis of the time to onset and resolution of irAEs associated with ipilimumab therapy. RESULTS Grade 2 through 5 irAEs generally developed during the induction phase of treatment (0-12 weeks). Most, including grade 3/4 irAEs, were reversible when managed with treatment guidelines using vigilant monitoring and corticosteroids. The median time to resolution (to grade 1 or 0 or to the grade at baseline) of irAEs that had an onset during the induction phase was approximately 6 weeks for grade 2 through 4 irAEs and 8 weeks for grade 3 and 4 irAEs. Across the entire study duration, most grade 2 through 4 irAEs resolved within 12 weeks. CONCLUSIONS Most ipilimumab-associated irAEs, including grade 3/4 symptoms, developed within 12 weeks of initial dosing and resolved within 12 weeks of onset. IrAEs were well characterized in their evolution and could be managed using published algorithms.

Abstract
Background Ipilimumab, a cytotoxic T-lymphocyte antigen-4 (CTLA-4) blocking antibody, has been approved for the treatment of metastatic melanoma and induces adverse events (AE) in up to 64% of patients. Treatment algorithms for the management of common ipilimumab-induced AEs have lead to a reduction of morbidity, e.g. due to bowel perforations. However, the spectrum of less common AEs is expanding as ipilimumab is increasingly applied. Stringent recognition and management of AEs will reduce drug-induced morbidity and costs, and thus, positively impact the cost-benefit ratio of the drug. To facilitate timely identification and adequate management data on rare AEs were analyzed at 19 skin cancer centers. Methods and Findings Patient files (n = 752) were screened for rare ipilimumab-associated AEs. A total of 120 AEs, some of which were life-threatening or even fatal, were reported and summarized by organ system describing the most instructive cases in detail. Previously unreported AEs like drug rash with eosinophilia and systemic symptoms (DRESS), granulomatous inflammation of the central nervous system, and aseptic meningitis, were documented. Obstacles included patientś delay in reporting symptoms and the differentiation of steroid-induced from ipilimumab-induced AEs under steroid treatment. Importantly, response rate was high in this patient population with tumor regression in 30.9% and a tumor control rate of 61.8% in stage IV melanoma patients despite the fact that some patients received only two of four recommended ipilimumab infusions. This suggests that ipilimumab-induced antitumor responses can have an early onset and that severe autoimmune reactions may reflect overtreatment. Conclusion The wide spectrum of ipilimumab-induced AEs demands doctor and patient awareness to reduce morbidity and treatment costs and true ipilimumab success is dictated by both objective tumor responses and controlling severe side effects.

Abstract
Because of dramatic tumor regressions reported with the anti-programmed death-1 (PD-1) and anti-programmed death ligand-1 (PDL-1) antibodies inhibiting the PD-1 immune checkpoint, non-small cell lung cancer (NSCLC) is now recognized as an immune-modifiable disease. As responses were observed in smaller numbers in phase I trials, the immunologic profiles and unique toxicities of these agents have not been fully established in NSCLC. Moreover, PD-1 checkpoint inhibitors in development by different companies may demonstrate diverse spectrums of activity and toxicity. Although the cytotoxic T-lymphocyte antigen-4 (CTLA-4) checkpoint inhibitors in earlier phase studies appeared to have less impressive responses in NSCLC, their safety profile has been more broadly defined. The anti-CTLA-4 antibody, ipilimumab, has the best characterized immune-related toxicities (predominantly skin, gastrointestinal, hepatic, and endocrine) and management strategies in melanoma. Despite the lack of studies directly comparing these agents, toxicities from PD-1 inhibition seem milder than those of CTLA-4 inhibition, with distinct toxicities of pneumonitis infrequently observed with the BMS-936558 anti-PD-1 antibody, nivolumamb, and frequent mild infusion reactions reported with the BMS-936559 anti-PDL-1 antibody. As lungs are critical organs often already compromised in NSCLC patients, immune-mediated pneumonitis can cause worrisome morbidity and mortality. Even though immune checkpoint inhibitors are being rapidly developed in a multitude of trials, optimal immune-mediated toxicity management has not been determined, is evolving, and will be further explored. Early diagnosis and symptom management with corticosteroids form the basis of treatment. Assessment of new immune-response criteria and use of primary endpoints of overall survival (OS) will be important in the development of these immunotherapies in NSCLC.

Abstract
Ipilimumab (Yervoy, developed by Medarex and Bristol-Myers Squibb) is a fully human monoclonal IgG1κ antibody against the cytotoxic T-lymphocyte antigen-4 (CTLA-4), an immune-inhibitory molecule expressed in activated T cells and in suppressor T regulatory cells. Interaction of the monoclonal antibody with CTLA-4 blocks inhibitory signals generated through this receptor and enhances T cell activation, leading to increased antitumor responses. Ipilimumab has been approved by FDA in March 2011 as monotherapy (3mg/kg every 3 weeks for 4 doses) for the treatment of advanced (unresectable or metastatic) melanoma both in pre-treated or chemotherapy naïve patients. Four months later, ipilimumab has received a rapid approval by the European Commission, after a positive opinion from the Committee for Medicinal Products for Human Use. However, the indication in the EU is limited to previously-treated patients with advanced melanoma. Ipilimumab is the first agent that has demonstrated to improve overall survival in patients with metastatic melanoma, which has a very poor prognosis, in randomized phase III clinical trials. The patterns of tumour response to ipilimumab differ from those observed with cytotoxic chemotherapeutic agents, since patients may have a delayed yet durable response and obtain long-term survival benefit despite an initial tumour growth. The major draw-back of ipilimumab is the induction of immune-related adverse effects; the latter can be life-threatening, unless promptly managed with immunosuppressive agents (most frequently corticosteroids) according to specific guidelines. Further development of ipilimumab includes its use in the neoadjuvant or adjuvant high-risk melanoma setting and for the treatment of other refractory and advanced solid tumours, either as single agent or in combination with additional immunostimulating agents or molecularly targeted therapies.
