ABSTRACT

BACKGROUND: A standard treatment for fit, older patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) is yet to be established. In the previous EXTREME trial, few older patients were included. We aimed to evaluate the efficacy and tolerance of an adapted EXTREME regimen in fit, older patients with recurrent or metastatic HNSCC. METHODS: This single-arm, phase 2 study was done at 22 centres in France. Eligible patients were aged 70 years or older and assessed as not frail (fit) using the ELAN Geriatric Evaluation (EGE) and had recurrent or metastatic HNSCC in the first-line setting that was not eligible for local therapy (surgery or radiotherapy), and an Eastern Cooperative Oncology Group performance status of 0-1. The adapted EXTREME regimen consisted of six cycles of fluorouracil 4000 mg/m2 on days 1-4, carboplatin with an area under the curve of 5 on day 1, and cetuximab on days 1, 8, and 15 (400 mg/m2 on cycle 1-day 1, and 250 mg/m2 subsequently), all intravenously, with cycles starting every 21 days. In patients with disease control after two to six cycles, cetuximab 500 mg/m2 was continued once every 2 weeks as maintenance therapy until disease progression or unacceptable toxicity. Granulocyte colony-stimulating factor was systematically administered and erythropoietin was recommended during chemotherapy. The study was based on the two-stage Bryant and Day design, combining efficacy and toxicity endpoints. The primary efficacy endpoint was objective response rate at week 12 after the start of treatment, assessed by central review (with an unacceptable rate of ≤15%). The primary toxicity endpoint was morbidity, defined as grade 4-5 adverse events, or cutaneous rash (grade ≥3) that required cetuximab to be discontinued, during the chemotherapy phase, or a decrease in functional autonomy (Activities of Daily Living score decrease ≥2 points from baseline) at 1 month after the end of chemotherapy (with an unacceptable morbidity rate of >40%). Analysis of the coprimary endpoints, and of safety in the chemotherapy phase, was based on the per-protocol population, defined as eligible patients who received at least one cycle of the adapted EXTREME regimen. Safety in the maintenance phase was assessed in all patients who received at least one dose of cetuximab as maintenance therapy. The study is registered with ClinicalTrials.gov, NCT01864772, and is completed. FINDINGS: Between Sept 27, 2013, and June 20, 2018, 85 patients were enrolled, of whom 78 were in the per-protocol population. 66 (85%) patients were male and 12 (15%) were female, and the median age was 75 years (IQR 72-79). The median number of chemotherapy cycles received was five (IQR 3-6). Objective response at week 12 was observed in 31 patients (40% [95% CI 30-51]) and morbidity events were observed in 24 patients (31% [22-42]). No fatal adverse events occurred. Four patients presented with a decrease in functional autonomy 1 month after the end of chemotherapy versus baseline. During chemotherapy, the most common grade 3-4 adverse events were haematological events (leukopenia [22 patients; 28%], neutropenia [20; 26%], thrombocytopenia [15; 19%], and anaemia [12; 15%]), oral mucositis (14; 18%), fatigue (11; 14%), rash acneiform (ten; 13%), and hypomagnesaemia (nine; 12%). Among 44 patients who received cetuximab during the maintenance phase, the most common grade 3-4 adverse events were hypomagnesaemia (six patients; 14%) and acneiform rash (six; 14%). INTERPRETATION: The study met its primary objectives on objective response and morbidity, and showed overall survival to be as good as in younger patients treated with standard regimens, indicating that the adapted EXTREME regimen could be used in older patients with recurrent or metastatic HNSCC who are deemed fit with use of a geriatric evaluation tool adapted to patients with head and neck cancer, such as the EGE.

ABSTRACT

BACKGROUND: At present, there is no established standard treatment for frail older patients with recurrent or metastatic head and neck squamous cell carcinoma. We aimed to compare the efficacy and safety of cetuximab to those of methotrexate (the reference regimen) in this population. METHODS: This randomised, open-label, phase 3 trial was done at 20 hospitals in France. Patients aged 70 years or older, assessed as frail by the ELAN Geriatric Evaluation, with recurrent or metastatic head and neck squamous cell carcinoma in the first-line setting and with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 were eligible for inclusion. Patients were randomly assigned (1:1) to receive cetuximab 500 mg/m2 intravenously every 2 weeks or methotrexate 40 mg/m2 intravenously every week, with minimisation by ECOG performance status, type of disease evolution, Charlson Comorbidity Index score, serum albumin concentration, and geriatrician consultation. To avoid deterministic minimisation and assure allocation concealment, patients were allocated with a probability of 0·80 to the treatment that most reduced the imbalance. Treatment was continued until disease progression or unacceptable toxicity, whichever occurred first. The primary endpoint was failure-free survival (defined as the time from randomisation to disease progression, death, discontinuation of treatment, or loss of 2 or more points on the Activities in Daily Living scale, whichever occurred first) and was analysed in the intention-to-treat population. 151 failures expected out of 164 patients were required to detect a hazard ratio (HR) of 0·625 with 0·05 alpha error, with 80% power. A futility interim analysis was planned when approximately 80 failures were observed, based on failure-free survival. Safety analyses included all patients who received at least one dose of the study drug. This study is registered on ClinicalTrials.gov (NCT01884623) and was stopped for futility after the interim analysis. FINDINGS: Between Nov 7, 2013, and April 23, 2018, 82 patients were enrolled (41 to the cetuximab group and 41 to the methotrexate group); 60 (73%) were male, 37 (45%) were aged 80 years or older, 35 (43%) had an ECOG performance status of 2, and 36 (44%) had metastatic disease. Enrolment was stopped for futility at the interim analysis. At the final analysis, median follow-up was 43·3 months (IQR 30·8-52·1). At data cutoff, all 82 patients had failure; failure-free survival did not differ significantly between the groups (median 1·4 months [95% CI 1·0-2·1] in the cetuximab group vs 1·9 months [1·1-2·6] in the methotrexate group; adjusted HR 1·03 [95% CI 0·66-1·61], p=0·89). The frequency of patients who had grade 3 or worse adverse events was 63% (26 of 41) in the cetuximab group and 73% (30 of 41) in the methotrexate group. The most common grade 3-4 adverse events in the cetuximab group were fatigue (four [10%] of 41 patients), lung infection (four [10%]), and rash acneiform (four [10%]), and those in the methotrexate group were fatigue (nine [22%] of 41), increased gamma-glutamyltransferase (seven [17%]), natraemia disorder (four [10%]), anaemia (four [10%]), leukopenia (four [10%]), and neutropenia (four [10%]). The frequency of patients who had serious adverse events was 44% (18 of 41) in the cetuximab group and 39% (16 of 41) in the methotrexate group. Four patients presented with a fatal adverse event in the cetuximab group (sepsis, decreased level of consciousness, pulmonary oedema, and death of unknown cause) as did two patients in the methotrexate group (dyspnoea and death of unknown cause). INTERPRETATION: The study showed no improvement in failure-free survival with cetuximab versus methotrexate. Patients with an ECOG performance status of 2 did not benefit from these systemic therapies. New treatment options including immunotherapy should be explored in frail older patients with recurrent or metastatic head and neck squamous cell carcinoma, after an initial geriatric evaluation, such as the ELAN Geriatric Evaluation.

ABSTRACT

BACKGROUND: A synergy between radiotherapy and anti-cytotoxic-T-lymphocyte-associated antigen 4 (anti-CTLA-4) monoclonal antibody has been demonstrated preclinically. The Mel-Ipi-Rx phase 1 study aimed to determine the maximum tolerated dose (MTD) and safety profile of radiotherapy combined with ipilimumab in patients with metastatic melanoma. PATIENTS AND METHODS: A 3+3 dose escalation design was used with 9, 15, 18 and 24 Gy dose of radiotherapy at week 4 combined with 10 mg/kg ipilimumab every 3 weeks for four doses. Patients with evidence of clinical benefit at week 12 were eligible for maintenance with ipilimumab 10 mg/kg every 12 weeks starting at week 24 until severe toxicity or disease progression. The database lock occurred on April 30, 2019. Tumor growth rate of irradiated lesions and non-irradiated lesions were analyzed to assess the systemic immunologic antitumor response. Blood immune monitoring was performed before and during treatment to determine if radiotherapy could modify ipilimumab pharmacodynamics. RESULTS: 19 patients received ipilimumab between August 2011 and July 2015. Nine patients received the four doses of ipilimumab. All patients received the combined radiotherapy. Grade 3 adverse events occurred in nine patients, the most common being colitis and hepatitis. No drug-related death occurred. Dose limiting toxicity occurred in two of six patients in the cohort receiving 15 Gy. The MTD was 9 Gy. Two patients had complete response, three had partial response response and seven had stable disease, giving an objective response rate of 31% and a clinical benefit rate of 75% at week 24. The median duration of follow-up was 5.8 years (Q1=4.5; Q3=6.8). The median overall survival (95% CI) was estimated at 0.9 years (0.5-2). The median progression-free survival (PFS) (95% CI) was 0.4 (0.2-1.4). Radiotherapy combined with ipilimumab was associated with increased CD4+ and CD8+ICOS+ T cells. Increased CD8+ was significantly associated with PFS. CONCLUSION: When combined with ipilimumab at 10 mg/kg, the MTD of radiotherapy was 9 Gy. This combination of ipilimumab and radiotherapy appears to be associated with antitumor activity. Increased CD8+ was significantly associated with PFS. Thus, immune biomarkers may be useful for early response evaluation. TRIAL REGISTRATION NUMBER: NCT01557114.

ABSTRACT

BACKGROUND: Vaginal/uterine rhabdomyosarcoma (VU RMS) is one of the most favorable RMS sites. To determine the optimal therapy, the experience of four cooperative groups (Children's Oncology Group [COG], International Society of Pediatric Oncology (SIOP) Malignant Mesenchymal Tumor Group [MMT], Italian Cooperative Soft Tissue Sarcoma Group [ICG], and European pediatric Soft tissue sarcoma Study Group [EpSSG]) was analyzed. PROCEDURE: From 1981 to 2009, 237 patients were identified. Median age (years) at diagnosis differed by tumor location; it was 1.9 for vagina (n = 160), 2.7 for uterus corpus (n = 26), and 13.5 for uterus cervix (n = 51). Twenty-eight percent of patients received radiation therapy (RT) as part of primary therapy (23% COG, 27% MMT, 46% ICG, and 42% EpSSG), with significant differences in the use of brachytherapy between the cooperative groups (23% COG, 76% MMT, 64% ICG, and 88% EpSSG). RESULTS: Ten-year event-free (EFS) and overall survival (OS) were 74% (95% CI, 67-79%) and 92% (95% CI, 88-96%), respectively. In univariate analysis, OS was inferior for patients with uterine RMS and for those with regional lymph node involvement. Although EFS was slightly lower in patients without initial RT (71% without RT vs. 81% with RT; P = 0.08), there was no difference in OS (94% without RT vs. 89% with RT; P = 0.18). Local control using brachytherapy was excellent (93%). Fifty-one (51.5%) of the 99 survivors with known primary therapy and treatment for relapse were cured with chemotherapy with or without conservative surgery. CONCLUSIONS: About half of all patients with VU RMS can be cured without systematic RT or radical surgery. When RT is indicated, modalities that limit sequelae should be considered, such as brachytherapy.
