Immune checkpoint inhibition with the anti-CTLA-4 antibody ipilimumab and the anti-PD-1 antibodies nivolumab and pembrolizumab has improved survival in metastatic melanoma, lung cancer and renal cancer. Use of these agents holds promise in other malignancies. The augmented immune response enabled by these agents has led to a particular group of side effects called immune-related adverse events (irAEs). The main irAEs include diarrhea, colitis, hepatitis, skin toxicities and endocrinopathies such as hypophysitis and thyroid dysfunction. The anti-PD-1 antibodies have a different toxicity profile to ipilimumab with fewer high grade events. This article identifies the rates of common and uncommon irAEs associated with each immune checkpoint inhibitor (ICPI) and their timing of onset, focusing mainly on the experience in melanoma and lung cancer. An approach to management for each class of irAE is provided. 相似文献

ABSTRACTIntroduction: The use of immune checkpoint inhibitors for the treatment of advanced melanoma has evolved beyond monotherapies such as ipilimumab and nivolumab to combination strategies involving both. This combination approach results in response rates around 60% and superior progression-free survival compared with ipilimumab monotherapy (median 11.5 versus 2.9 months).Areas covered: A comprehensive literature search was undertaken including search terms of ‘ipilimumab and nivolumab’ and ‘combination immune checkpoint therapy’. Relevant information contained in abstracts and conference presentations was included. This article summarizes the mechanism of action, efficacy and safety of combination ipilimumab and nivolumab across Phase I, II and III clinical trials. It also describes the place of combination therapy in the current market of advanced melanoma treatment options.Expert Opinion: Efficacy for the combination approach is seen across a wide array of subgroups and occurs regardless of BRAF mutation status. Counterbalancing the apparent advantages, combination ipilimumab with nivolumab is associated with a high rate (55%) of grade 3/4 adverse events leading to discontinuation in a third of those treated. Most of these are manageable and do not appear to compromise durability of response. Overall survival information is currently immature but appears promising. 相似文献

New antitumour immunotherapy strategies for stage iv metastatic melanoma include ipilimumab, a monoclonal antibody against ctla-4. Patterns of response with cancer immunotherapy differ from those with cytotoxic chemotherapy. We present two cases of long-duration immune-related responses with ipilimumab in a phase ii trial.A 66-year-old woman with multiple lung metastases from a scalp primary melanoma received 4 doses of ipilimumab with mixed clinical response. However, after the first maintenance dose, she developed severe ileitis and colitis that responded to steroid therapy. Four months later, she had surgery and radiotherapy for a single brain metastasis. Radiologically, stable disease continued for 36 months after the last ipilimumab dose, and partial response for 5 years after ipilimumab start.A 54-year-old man with cervical lymph node and pulmonary metastases from a scalp primary melanoma received three induction doses of ipilimumab. He developed alopecia universalis and widespread vitiligo, and he discontinued treatment because of hypophysitis. Maintenance ipilimumab was started after a 6-month drug-free interval, with no further adverse events over 15 cycles. At week 12, computed tomography imaging showed no lung metastases and partial response in a supraclavicular lymph node, which was positive on positron-emission tomography. Five years after starting ipilimumab, the supraclavicular lymph node was calcified, and the patient was off steroid therapy and asymptomatic.The foregoing patients demonstrate long responses with ipilimumab (in association with delayed severe colitis in one case, and a constellation of immune events, including alopecia universalis in another). Re-treatment with ipilimumab may be possible even after significant immune adverse events. 相似文献

Administration of ipilimumab,a cytotoxic T-lymphocyte associated antigen-4-blocking monoclonal antibody,leads to enhancement of the anti-tumor T-cell respons and as a result shows a significant survival benefit in metastatic melanoma patients.Therefore patients are currently receiving this promising therapy as a secondline strategy.Unfortunately,by activation of the T-cell immune reponse,ipilimumab therapy may lead to an unwanted induction of different autoimmune phenomena.Diarrhoea and colitis occur in up to one third of patients.Here we present a case of ipilimumab induced ileocolitis which was successfully treated with infliximab,an anti-tumor necrosis factor monoclonal antibody,after corticosteroid therapy failure.Although formal trials are lacking,recently publicated series suggest that infusional therapy of infliximab is effective in ipilimumab induced ileocolitis. 相似文献

IntroductionIpilimumab plus nivolumab has been approved for intermediate- and poor-risk metastatic renal cell carcinoma (RCC). However, the activity in non–clear cell RCC (nccRCC) is unknown.Patients and MethodsPatients from Cleveland Clinic and the University of Texas Southwestern who had received ipilimumab plus nivolumab for metastatic nccRCC from October 2017 to May 2019 were retrospectively identified. Ipilimumab plus nivolumab was administered in accordance with the CHECKMATE 214 trial. Imaging was obtained at baseline and every 12 weeks. The baseline patient characteristics, objective response per Response Evaluation Criteria in Solid Tumors, version 1.1, and treatment-related adverse events (TRAEs) per Common Terminology Criteria for Adverse Events, version 5.0, were analyzed.ResultsEighteen patients were identified. The median age was 59 years (range, 32-81 years), 77.8% were men, and the Eastern Cooperative Oncology Group performance status was 0 (38%) or 1 (50%). The median treatment duration was 2.4 months (range, 0.7-12.3 months). The non–clear cell histologic types included 6 papillary, 5 chromophobe, 3 unclassified, 2 adenocarcinoma of renal origin, 1 translocation, and 1 medullary. Most had an intermediate (66%) or poor (22%) International Metastatic Database Consortium risk. The best objective response included 6 partial responses (PRs; 33.3%) and 3 with stable disease (16.7%). Of the patients with a PR, the median time to the best response was 3.0 months, and median duration of the PR was 4.3 months. The median progression-free survival was 7.1 months. All-grade TRAEs were noted in 11 patients (61.1%) and included colitis (22%), hepatotoxicity (16%), rash (11%), and fatigue (11%). Eleven patients (61%) had TRAEs requiring high-dose glucocorticoids (> 40 mg of prednisone equivalent daily).ConclusionsIpilimumab plus nivolumab demonstrated objective responses and notable toxicity in patients with nccRCC. 相似文献
