ABSTRACT: Background
The combination of PD-1/PD-L1 inhibitor and chemotherapy has been clinically confirmed to be beneficial as the first-line treatment of patients with advanced NSCLC. This study aimed to assess the effect of nivolumab + docetaxel versus nivolumab monotherapy in patients with NSCLC after the failure of platinum doublet chemotherapy.Materials and methods
The efficacy and toxicity of nivolumab + docetaxel combination therapy versus nivolumab monotherapy were compared in this retrospective study. Primary endpoint of the study was progression-free survival (PFS), and the secondary endpoints were objective response rate (ORR), overall survival (OS), and toxicity.Results
Between November 2017 and December 2019, 77 patients were included in this study, with 58 patients in the nivolumab group and 19 in the nivolumab + docetaxel group. The median follow-up was 18 months, and the PFS was 8 months for patients receiving nivolumab + docetaxel and 2 months for those receiving nivolumab alone (p = 0.001), respectively. Nivolumab + docetaxel showed superior OS compared with nivolumab, with the median OS unreached versus 7 months (p = 0.011). Among patients without EGFR/ALK variation, compared to nivolumab monotherapy, nivolumab + docetaxel showed better PFS (p = 0.04) and OS (p = 0.05). There was no significant difference in grade 3-4 adverse events (AEs) between the two groups (p = 0.253).Conclusions
The combination of nivolumab and docetaxel demonstrated a meaningful improvement in progression-free survival and overall survival compared to nivolumab monotherapy, in patients with NSCLC after the failure of platinum doublet chemotherapy, irrespective of EGFR/ALK variation status.

Project description:IntroductionMET amplification is an important genetic alteration in NSCLC. Unlike in patients with EGFR and ALK alterations, the efficacy of immune checkpoint inhibitors in patients with MET-amplified NSCLC remains unknown.MethodsAn exploratory analysis of a prospective, multi-institutional cohort comprising 200 patients with advanced or recurrent NSCLC treated with nivolumab monotherapy was performed, and MET amplification was defined as a MET-to-CEP7 ratio of greater than or equal to 2 using fluorescent in situ hybridization. High-level and low-level MET gains were also defined as MET signals ≥10/nuclei and 10> MET signals ≥5/nuclei, respectively. Overall response rates (ORRs) and survival outcomes were evaluated on the basis of the MET gene copy number status.ResultsAmong 175 patients eligible for analysis, MET amplification was detected in 13 tumors (7.4%). Four (2.3%) high-level and 14 (8.0%) low-level MET gains were also detected. There were no considerable differences in ORRs in accordance with the MET gene copy number status. Similarly, no significant differences in both progression-free survival (PFS) and overall survival (OS) were observed between patients with and without MET-amplified NSCLC (log-rank, p = 0.813 for PFS, and p = 0.855 for OS). Among 101 adenocarcinomas, ORRs in patients with high-level and low-level MET gains (50.0% for both, p = 0.049) were significantly higher than those without MET gains (17.6%), yet survival outcomes for both PFS and OS did not improve.ConclusionsMET amplification was not associated with greater benefit of nivolumab treatment in patients with NSCLC. Further studies are warranted to prioritize immune checkpoint inhibitors in the treatment regimen for patients with MET amplification.

Project description:The efficacies of pembrolizumab and nivolumab have never been directly compared in a real-world study. Therefore, we sought to retrospectively evaluate the objective response rate (ORR) and the progression-free survival (PFS) of patients with recurrent or advanced non-small cell lung cancer (NSCLC) in a real-world setting. This study included patients with recurrent or advanced NSCLC diagnosed between September 1, 2015 and August 31, 2019, who were treated with programmed cell death 1 (PD-1) inhibitors at the Cancer Center of the Chinese People's Liberation Army. PFS was estimated for each treatment group using Kaplan-Meier curves and log-rank tests. The multivariate analysis of PFS was performed with Cox proportional hazards regression models. A total of 255 patients with advanced or recurrent NSCLC treated with PD-1 inhibitors were identified. The ORR was significantly higher in the pembrolizumab group than in the nivolumab group, while PFS was not significantly different between the two groups. Subgroup analysis showed that the ORR was significantly higher for pembrolizumab than for nivolumab in patients in the first-line therapy subgroup and in those in the combination therapy as first-line therapy subgroup. Survival analysis of patients receiving combination therapy as second- or further-line therapy showed that nivolumab had better efficacy than pembrolizumab. However, the multivariate analysis revealed no significant difference in PFS between patients treated with pembrolizumab and those treated with nivolumab regardless of the subgroup. In our study, no significant difference in PFS was noted between patients treated with pembrolizumab and those treated with nivolumab in various clinical settings. This supports the current practice of choosing either pembrolizumab or nivolumab based on patient preferences.

Project description:PurposeThe advent of immune checkpoint inhibitors (ICIs) has revolutionized the treatment of advanced NSCLC, leading to a string of approvals in recent years. Herein, a narrative review on the role of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) in the ever-evolving treatment landscape of advanced NSCLC is presented.MethodsThis comprehensive review will begin with an introduction into current treatment paradigms incorporating ICIs; the evolution of CT-based criteria; moving onto novel phenomena observed with ICIs and the current state of hybrid imaging for diagnosis, treatment planning, evaluation of treatment efficacy and toxicity in advanced NSCLC, also taking into consideration its limitations and future directions.ConclusionsThe advent of ICIs marks the dawn of a new era bringing forth new challenges particularly vis-à-vis treatment response assessment and observation of novel phenomena accompanied by novel systemic side effects. While FDG PET/CT is widely adopted for tumor volume delineation in locally advanced disease, response assessment to immunotherapy based on current criteria is of high clinical value but has its inherent limitations. In recent years, modifications of established (PET)/CT criteria have been proposed to provide more refined approaches towards response evaluation. Not only a comprehensive inclusion of PET-based response criteria in prospective randomized controlled trials, but also a general harmonization within the variety of PET-based response criteria is pertinent to strengthen clinical implementation and widespread use of hybrid imaging for response assessment in NSCLC.

Project description:PurposeTo investigate the efficacy and safety of concurrent stereotactic radiosurgery (SRS) and ipilimumab or nivolumab in patients with untreated melanoma brain metastases.Patients and methodsEighty consecutive patients with 326 melanoma brain metastases receiving SRS in combination with ipilimumab or nivolumab were identified from an institutional database and retrospectively evaluated. Patients started systemic treatment with intravenous nivolumab or ipilimumab within one week of receiving SRS. Nivolumab was given at doses of 3 mg/kg every two weeks. Ipilimumab was administered up to four doses of 10 mg/kg, one every 3 weeks, then patients had a maintenance dose of 10 mg/kg every 12 weeks, until disease progression or inacceptable toxicity. Primary endpoint of the study was intracranial progression-free survival (PFS). Secondary endpoints were extracranial PFS, overall survival (OS), and neurological toxicity.ResultsEighty patients were analyzed. Forty-five patients received SRS and ipilimumab, and 35 patients received SRS and nivolumab. With a median follow-up of 15 months, the 6-month and 12-month intracranial PFS rates were 69% (95%CI,54-87%) and 42% (95%CI,24-65%) for patients receiving SRS and nivolumab and 48% (95%CI,34-64%) and 17% (95%CI,5-31%) for those treated with SRS and ipilimumab (p = 0.02), respectively. Extracranial PFS and OS were 37 and 78% in SRS and nivolumab group, respectively, and 17 and 68% in SRS and ipilimumab group, respectively, at 12 months. Sub-group analysis showed significantly better intracranial PFS for patients receiving multi-fraction SRS (3 × 9 Gy) compared to single-fraction SRS (70% versus 46% at 6 months, p = 0.01), especially in combination with nivolumab. Grade 3 treatment-related adverse events occurred in 11 (24%) patients treated with SRS and ipilimumab and 6 (17%) patients who received SRS and nivolumab. Radiation-induced brain necrosis (RN) occurred in 15% of patients.ConclusionsConcurrent SRS and ipilimumab or nivolumab show meaningful intracranial activity in patients with either asymptomatic and symptomatic melanoma brain metastases, although a subset of patients may develop symptomatic RN. The combination of nivolumab with SRS is associated with better intracranial control.

Project description:Nivolumab, a fully human IgG4 programmed death 1 (PD-1) immune-checkpoint-inhibitor antibody, disrupts PD-1-mediated signaling and may restore antitumor immunity.In this randomized, open-label, international phase 3 study, we assigned patients with nonsquamous non-small-cell lung cancer (NSCLC) that had progressed during or after platinum-based doublet chemotherapy to receive nivolumab at a dose of 3 mg per kilogram of body weight every 2 weeks or docetaxel at a dose of 75 mg per square meter of body-surface area every 3 weeks. The primary end point was overall survival.Overall survival was longer with nivolumab than with docetaxel. The median overall survival was 12.2 months (95% confidence interval [CI], 9.7 to 15.0) among 292 patients in the nivolumab group and 9.4 months (95% CI, 8.1 to 10.7) among 290 patients in the docetaxel group (hazard ratio for death, 0.73; 96% CI, 0.59 to 0.89; P=0.002). At 1 year, the overall survival rate was 51% (95% CI, 45 to 56) with nivolumab versus 39% (95% CI, 33 to 45) with docetaxel. With additional follow-up, the overall survival rate at 18 months was 39% (95% CI, 34 to 45) with nivolumab versus 23% (95% CI, 19 to 28) with docetaxel. The response rate was 19% with nivolumab versus 12% with docetaxel (P=0.02). Although progression-free survival did not favor nivolumab over docetaxel (median, 2.3 months and 4.2 months, respectively), the rate of progression-free survival at 1 year was higher with nivolumab than with docetaxel (19% and 8%, respectively). Nivolumab was associated with even greater efficacy than docetaxel across all end points in subgroups defined according to prespecified levels of tumor-membrane expression (?1%, ?5%, and ?10%) of the PD-1 ligand. Treatment-related adverse events of grade 3 or 4 were reported in 10% of the patients in the nivolumab group, as compared with 54% of those in the docetaxel group.Among patients with advanced nonsquamous NSCLC that had progressed during or after platinum-based chemotherapy, overall survival was longer with nivolumab than with docetaxel.

Project description:Patients with advanced squamous-cell non-small-cell lung cancer (NSCLC) who have disease progression during or after first-line chemotherapy have limited treatment options. This randomized, open-label, international, phase 3 study evaluated the efficacy and safety of nivolumab, a fully human IgG4 programmed death 1 (PD-1) immune-checkpoint-inhibitor antibody, as compared with docetaxel in this patient population.We randomly assigned 272 patients to receive nivolumab, at a dose of 3 mg per kilogram of body weight every 2 weeks, or docetaxel, at a dose of 75 mg per square meter of body-surface area every 3 weeks. The primary end point was overall survival.The median overall survival was 9.2 months (95% confidence interval [CI], 7.3 to 13.3) with nivolumab versus 6.0 months (95% CI, 5.1 to 7.3) with docetaxel. The risk of death was 41% lower with nivolumab than with docetaxel (hazard ratio, 0.59; 95% CI, 0.44 to 0.79; P<0.001). At 1 year, the overall survival rate was 42% (95% CI, 34 to 50) with nivolumab versus 24% (95% CI, 17 to 31) with docetaxel. The response rate was 20% with nivolumab versus 9% with docetaxel (P=0.008). The median progression-free survival was 3.5 months with nivolumab versus 2.8 months with docetaxel (hazard ratio for death or disease progression, 0.62; 95% CI, 0.47 to 0.81; P<0.001). The expression of the PD-1 ligand (PD-L1) was neither prognostic nor predictive of benefit. Treatment-related adverse events of grade 3 or 4 were reported in 7% of the patients in the nivolumab group as compared with 55% of those in the docetaxel group.Among patients with advanced, previously treated squamous-cell NSCLC, overall survival, response rate, and progression-free survival were significantly better with nivolumab than with docetaxel, regardless of PD-L1 expression level.

Project description:IntroductionImmunotherapy has revolutionized metastatic Melanoma therapy. The most active regimen is combination therapy of Ipilimumab-Nivolumab (Ipi-Nivo) with response rates (RR) of ~60% and median overall survival (OS) of ~6 years. Immune-related adverse events (irAE) are common (~60% develop grade 3-4) and pose a challenge when treating frail patients. We sought to examine whether Ipi-Nivo therapy is feasible in elderly metastatic melanoma patients.MethodsElectronic records of patients treated at the Ella Lemelbaum Institute with Ipi-Nivo between the years 2017-2021 were screened for age. Elderly patients were defined as age 75 and older (group A) and were matched with records of patients age <75 (group B). Records were analyzed for baseline parameters, immunotherapy regimen, RR, toxicity and progression-free survival (PFS).ResultsTwenty-six relevant patients age >75 (median 77) were identified and were matched to 34 younger patients (median age 57). No statistically significant differences were noted in terms of baseline parameters except for BRAF mutation status (group A 15%, group B 47%, p=0.008). Response rate in group A was 38% and is consistent with previously published data. Median PFS was the same for both groups (A = 5.5 months, B= 7.5 months, p=NS). Treatment was similarly tolerated: 35% of group A patients completed 4 cycles of therapy compared to 28% for group B (p=NS). Grade 2-4 irAE were the same (A=58%, B=66%, p=NS) and there was no difference in the need for hospitalization for G3-4 events between the groups. (A=63%, B=69%, p=NS). Further division into 4 age groups (>80 vs 75-79 in group A and 65-74 vs <65 in group B) found no difference in terms of response rate or G3-4 toxicity.ConclusionIpilimumab-Nivolumab combination therapy in elderly metastatic Melanoma patients seems to be well tolerated and efficient in selected elderly patients based on performance status and comorbidities, just as in younger patients. This regimen seems to be a feasible treatment option for this age group.

Project description:Squamous cell carcinoma of the thymus is a rare thymic epithelial neoplasm that tends to widely metastasize at initial presentation. Because of its rarity, the optimal chemotherapeutic regimen remains uncertain. A gemcitabine and cisplatin regimen has shown promising efficacy in the treatment of other squamous cell carcinomas. We assessed the efficacy and toxicity of this regimen in patients with advanced thymic squamous cell carcinoma.Between January 2003 and December 2012, 13 patients with untreated or unresectable recurrent thymic squamous cell carcinomas, who were treated with gemcitabine and cisplatin, were retrospectively analyzed. The endpoints in this study were clinical response rate, disease control rate, progression-free survival, and overall survival. Significant hematological and non-hematological toxicities were also assessed.Three patients were in Masaoka stage IVa and 10 were in stage IVb. The median number of treatment cycles for the present chemotherapy regimen was four. The clinical response and disease control rates were 61.5% and 92.3%, respectively. The median progression-free and median overall survival rates were 14.5 months (95% confidence interval, 9.2-19.8 months) and 50.7 months (95% confidence interval, 24.9-76.5 months), respectively. Grade 3/4 hematological toxicities were observed in seven (53.8%) patients, and non-hematological toxicities were mild.This retrospective analysis demonstrated that gemcitabine plus cisplatin was active against advanced thymic squamous cell carcinoma with manageable toxicity. Gemcitabine may be a novel and alternative agent for advanced thymic squamous cell carcinoma.

Project description:Antibodies against the immune checkpoint proteins PD-1 and PD-L1 are novel therapeutic drugs for the treatment of advanced non-small cell lung cancer (NSCLC). Many clinical trials involving these drugs achieved breakthroughs in patients previously treated for advanced NSCLC. However, the results of these clinical studies are not consistent. In this report, we performed a meta-analysis to assess the efficacy and safety of anti-PD-1/PD-L1 antibodies compared with docetaxel treatment for advanced NSCLC patients from 5 randomized clinical trials. We demonstrated that the patients in anti-PD-1/PD-L1 antibody therapy groups had significantly longer overall survival (OS) (HR = 0.69, 95% CI 0.63-0.75, P < 0.05) and progression-free survival (PFS) (HR = 0.76, 95% CI 0.63-0.92, P < 0.05) than those in chemotherapy groups, especially PD-L1 positive patients. Anti-PD-1/PD-L1 antibodies improved the objective response rate (ORR) compared with docetaxel (OR = 1.64, 95% CI 1.19-2.26, p < 0.05). In addition, the anti-PD-1/PD-L1 antibody therapy had fewer treatment-related adverse events (AEs) (OR = 0.33, 95% CI 0.28-0.39, P < 0.05) than docetaxel, especially the grade ≥3 AEs (OR = 0.18, 95% CI 0.12-0.28, P < 0.001). In conclusion, our study revealed that, compared with docetaxel, anti-PD-1/PD-L1 antibody therapy improved clinical efficacy and safety in previously treated advanced NSCLC patients. This therapy may be a promising treatment for advanced NSCLC patients.

Project description:BACKGROUND:Nivolumab combined with ipilimumab resulted in longer progression-free survival and a higher objective response rate than ipilimumab alone in a phase 3 trial involving patients with advanced melanoma. We now report 3-year overall survival outcomes in this trial. METHODS:We randomly assigned, in a 1:1:1 ratio, patients with previously untreated advanced melanoma to receive nivolumab at a dose of 1 mg per kilogram of body weight plus ipilimumab at a dose of 3 mg per kilogram every 3 weeks for four doses, followed by nivolumab at a dose of 3 mg per kilogram every 2 weeks; nivolumab at a dose of 3 mg per kilogram every 2 weeks plus placebo; or ipilimumab at a dose of 3 mg per kilogram every 3 weeks for four doses plus placebo, until progression, the occurrence of unacceptable toxic effects, or withdrawal of consent. Randomization was stratified according to programmed death ligand 1 (PD-L1) status, BRAF mutation status, and metastasis stage. The two primary end points were progression-free survival and overall survival in the nivolumab-plus-ipilimumab group and in the nivolumab group versus the ipilimumab group. RESULTS:At a minimum follow-up of 36 months, the median overall survival had not been reached in the nivolumab-plus-ipilimumab group and was 37.6 months in the nivolumab group, as compared with 19.9 months in the ipilimumab group (hazard ratio for death with nivolumab plus ipilimumab vs. ipilimumab, 0.55 [P<0.001]; hazard ratio for death with nivolumab vs. ipilimumab, 0.65 [P<0.001]). The overall survival rate at 3 years was 58% in the nivolumab-plus-ipilimumab group and 52% in the nivolumab group, as compared with 34% in the ipilimumab group. The safety profile was unchanged from the initial report. Treatment-related adverse events of grade 3 or 4 occurred in 59% of the patients in the nivolumab-plus-ipilimumab group, in 21% of those in the nivolumab group, and in 28% of those in the ipilimumab group. CONCLUSIONS:Among patients with advanced melanoma, significantly longer overall survival occurred with combination therapy with nivolumab plus ipilimumab or with nivolumab alone than with ipilimumab alone.
