RESUMO
BACKGROUND: Advanced esophageal squamous cell cancer (ESCC) is frequently diagnosed in elderly patients. The impact of 2nd line chemotherapy is poorly defined. Recent data demonstrated effectiveness of checkpoint inhibitors in different squamous cell carcinomas. Therefore, we assess combined nivolumab/ipilimumab as 2nd line therapy in elderly ESCC patients. METHODS: RAMONA is a multicenter open-label phase II trial. The primary objective is to demonstrate a significant survival benefit of nivolumab/ipilimumab in advanced ESCC compared to historical data of standard chemotherapy. Primary endpoint is therefore overall survival (OS). Major secondary objective is the evaluation of tolerability. Time to QoL deterioration will thus be determined as key secondary endpoint. Further secondary endpoints are tumor response, PFS and safety. We aim to recruit a total of n = 75 subjects that have to be > 65 years old. Eligibility is determined by the geriatric status (G8 screening and Deficit Accumulation Frailty Index (DAFI)). A safety assessment will be performed after a 3 cycle run-in phase of nivolumab (240 mg Q2W) to justify escalation for eligible patients to combined nivolumab (240 mg Q2W) and ipilimumab (1 mg/kg Q6W), while the other patients will remain on nivolumab only. RAMONA also includes translational research sub-studies to identify predictive biomarkers, including PD-1 and PD-L1 evaluation at different time points, establishment of organoid cultures and microbiome analyses for response prediction. DISCUSSION: The RAMONA trial aims to implement checkpoint inhibitors for elderly patients with advanced ESCC as second line therapy. Novel biomarkers for checkpoint-inhibitor response are analyzed in extensive translational sub-studies. TRIAL REGISTRATION: EudraCT Number: 2017-002056-86 ; NCT03416244 , registered: 31.1.2018.

BACKGROUND: In the group of elderly patients (≥70 years) with metastatic pancreatic ductal adenocarcinoma (mPDAC), it is not known who benefits from intensive 1st line nab-paclitaxel/gemcitabine (nab-p/gem) combination chemotherapy or who would rather suffer from increased toxicity. We aim to determine whether treatment individualization by comprehensive geriatric assessments (CGAs) improves functional outcome of the patients. METHODS/DESIGN: GrantPax is a multicenter, open label phase 4 interventional trial. We use a CGA to stratify elderly patients into three parallel treatment groups (n = 45 per arm): 1) GOGO (nab-p/gem), 2) SLOWGO (gem mono) or 3) FRAIL (best supportive care). After the 1st cycle of chemotherapy (or 4 weeks in FRAIL group) another CGA and safety assessment is performed. CGA-stratified patients may not decline in their CGA performance in response to the first cycle of chemotherapy (primary objective), measured as a loss of 5 points or less in Barthels activities of daily living. Based on the second CGA, patients are re-assigned to their definite treatment arm and undergo further CGAs to monitor the course of treatment. Secondary endpoints include CGA scores during the course of therapy (CGA1-4), response rates, safety and survival rates. DISCUSSION: GrantPax is the first trial implementing a CGA-driven treatment to personalize therapy for elderly patients with pancreatic cancer. This may lead to standardization of therapy decisions for elderly patients and may optimize standard of care for this increasing group of patients.

INTRODUCTION: The phase 2 RAMONA study demonstrated that second-line nivolumab ± ipilimumab immunotherapy was feasible and effective in older patients with advanced esophageal squamous cell cancer (ESCC). Here, we presented results from functional status (FS) and quality-of-life (QoL) analyses. MATERIALS AND METHODS: Patients aged ≥65 years with advanced ESCC and disease progression following first-line therapy were enrolled for study treatment with nivolumab ± ipilimumab. Geriatric assessments (GA) consisting of G8 and GoGo/SlowGo evaluation, and quality of life (QoL) assessments with EORTC QLQ-C30 questionnaires were conducted at baseline and during the treatment. A post hoc analysis was performed to compare therapy efficacy, toxicity, and QoL between age groups (≥70 years vs. <70 years) and functionality groups (G8 > 14 vs. ≤14 and GoGo vs. SlowGo). RESULTS: In 66 treated patients with a median age of 70.5 years, older patients had non-inferior overall survival and tumor response compared to younger patients, with no increased treatment-related adverse events. Fitter patients (G8 > 14, GoGo) had a clinically, yet not statistically significant, survival advantage than less fit patients (G8 ≤ 14, SlowGo) patients. Moreover, FS by G8 and GoGo/SlowGo significantly correlated with QoL. Overall, QoL was impaired at baseline but remained stable in all scales over the course of immunotherapy. DISCUSSION: The administration of nivolumab ± ipilimumab second-line immunotherapy in older patients with ESCC did not show age-dependent effects and maintained QoL. GA could identify functional deficits and limitations of QoL and should be implemented in the context of immunotherapy. CLINICALTRIALS: gov: NCT03416244.

BACKGROUND: The overall survival of patients with advanced and refractory oesophageal squamous cell carcinoma, mostly aged 65 years and older, is poor. Treatment with PD-1 antibodies showed improved progression-free survival and overall survival. We assessed the safety and efficacy of combined nivolumab and ipilimumab therapy in this population. METHODS: This multicentre, open-label, phase 2 trial done in 32 sites in Germany included patients aged 65 years and older with oesophageal squamous cell carcinoma and disease progression or recurrence following first-line therapy. Patients were treated with nivolumab (240 mg fixed dose once every 2 weeks, intravenously) in the safety run-in phase and continued with nivolumab and ipilimumab (nivolumab 240 mg fixed dose once every 2 weeks and ipilimumab 1 mg/kg once every 6 weeks, intravenously). The primary endpoint was overall survival, which was compared with a historical cohort receiving standard chemotherapy in the intention-to-treat population. This study is registered with ClinicalTrials.gov, NCT03416244. FINDINGS: Between March 2, 2018, and Aug 20, 2020, we screened 75 patients with advanced oesophageal squamous cell carcinoma. We enrolled 66 patients (50 [76%] men and 16 [24%] women; median age 70·5 years [IQR 67·0-76·0]), 44 (67%) of whom received combined nivolumab and ipilimumab therapy and 22 (33%) received nivolumab alone. Median overall survival time at the prespecified data cutoff was 7·2 months (95% CI 5·7-12·4) and significantly higher than in a historical cohort receiving standard chemotherapy (p=0·0063). The most common treatment-related adverse events were fatigue (12 [29%] of 42), nausea (11 [26%]), and diarrhoea (ten [24%]). Grade 3-5 treatment-related adverse events occurred in 13 (20%) of 66 patients. Treatment-related death occurred in one patient with bronchiolitis obliterans while on nivolumab and ipilimumab treatment. INTERPRETATION: Patients aged at least 65 years, with advanced oesophageal squamous cell carcinoma might benefit from combined nivolumab and ipilimumab therapy in second-line treatment.

The current chemotherapeutic treatment of glioblastoma patients has minor success. Little is known about the molecular and cellular mechanisms of the resistance of gliomas towards current therapies. This study investigated both suppressive cellular effects and regulation of extracellular matrix remodeling proteins with pro-invasive activity in surviving human glioblastoma cells under clinically relevant treatments. All cellular and molecular biological investigations were performed on the genetically well-defined and clinically relevant p53-wild type U87Mg glioma cells. Malignant glioma cells underwent either radiation or temozolomide treatments alone, or combined chemo/radio treatment. Protein expression patterns were investigated by two-dimensional polyacrylamide gel electrophoresis followed by protein spot identification using tandem mass spectrometry analysis. Specific expression levels were quantified by Western-blotting. Extracellular gelatinase activities for both metalloproteinases MMP-2 and MMP-9 were determined by zymogramms. Survival curves indicated no effective suppression of glioma cells under all treatment conditions tested. Morphological changes demonstrated sub-lethal effect of both temozolomide and combined treatment. Expression of MMP-2, MMP-9, and membrane type 1 matrix metalloproteinases (MT1-MMP) was differentially up-regulated by increasing cellular density and treatment conditions. A significantly enhanced extracellular degrading activity under all treatment conditions tested was demonstrated for MMP-2 only. Being a marker for brain tumour progression and angiogenesis, lysozyme c was highly up-regulated under the combined chemo/radio treatment. The activation of proteins with pro-invasive activity indicates an increasing malignancy grade of surviving glioma cells under treatment conditions tested correlating well with more aggressive tumour phenotypes observed clinically in recurrences of treated glioblastomas.
