Filter by:The epidermal growth factor receptor (EGFR) is both oncogene and prognostic biomarker in head and neck squamous cell carcinoma (HNSCC). EGFR's functional importance in HNSCC resulted in development of the first molecularly targeted strategy, the anti-EGFR monoclonal antibody cetuximab. Given the lack of therapeutic options for patients with recurrent/metastatic HNSCC after failure of cetuximab, there is strong scientific interest in understanding resistance in order to identify new therapies for this population. A possible resistance mechanism to anti-EGFR therapy in HNSCC is primary or compensatory activation of alternate growth factor receptors including c-Met. The MET oncogene encodes c-Met, an RTK bound exclusively by the ligand, hepatocyte growth factor (HGF). The HGF/c-Met signaling pathway converges with the EGFR network at both the PI3K/Akt and MAPK nodes. Laboratory data suggest the ability for reciprocal compensation between EGFR and c-Met. We hypothesize that HGF/c-Met pathway inhibition may overcome resistance to cetuximab in patients with HNSCC, such as those with clinical cetuximab resistance. Ficlatuzumab (AV-299) is a humanized HGF-inhibitory immunoglobulin G1 (IgG1) monoclonal antibody. The primary objective of this phase 1b study is to find the recommended phase II dose (RP2D) of the combination of ficlatuzumab and cetuximab in patients with recurrent/metastaticHNSCC. The dose-finding study design will follow a Narayana k-in-a-row design with k set to 2 to target a 33% rate of dose-limiting toxicity (DLT). In the dose-finding phase, a total of 8 patients will be treated if no DLTs are observed or 14 patients if at least one DLT occurs. An expansion cohort will then proceed at RP2D until 12 patients have been treated at that dose level with the combination of ficlatuzumab and cetuximab. We will evaluate biomarkers of HGF/cMet pathway activation in baseline tissue, plasma and immune cells for a preliminary relationship with clinical activity.
Head and neck squamous cell carcinoma (HNSCC) is the most common cancer arising in the upper aerodigestive tract, and is the sixth leading incident cancer worldwide. Despite advances in multimodality therapy, 5-year overall survival (OS) is 40-60%, and has increased only incrementally in the past two decades. The current standard of care for primary nonsurgical management of locally advanced HNSCC is concurrent cisplatin-radiotheray, which significantly improved OS, progression-free survival, and locoregional control compared with radiotherapy alone in the landmark Intergroup trial 0126. The MET proto-oncogene encodes c-Met, a heterodimeric growth factor receptor bound exclusively by its ligand, hepatocyte growth factor (HGF). In the laboratory, activation of the HGF/c-Met pathway is associated with resistance to cisplatin and radiotherapy in HNSCC. We hypothesize that the addition of an HGF/c-Met pathway inhibitor to cisplatin-radiotherapy may improve outcomes in HNSCC. Ficlatuzumab (AV-299) is a humanized HGF-inhibitory IgG1 monoclonal antibody. The primary objective of this study is to establish the recommended phase II dose (RP2D) of the combination of ficlatuzumab, cisplatin and intensity-modulated radiotherapy (IMRT), in patients with locally advanced HNSCC. The dose-finding study design will follow a Narayana k-in-a-row design with k set to 3 to target a 33% DLT rate. In the dose-finding phase, a total of either 10 or 14 patients will be treated. If no DLTs are observed among 10 patients, the highest dose tier will be declared the RP2D. Otherwise the RP2D will be estimated from DLTs across all dose levels by isotonic regression. The secondary objective is to estimate biomarker association with preliminary clinical response. We will evaluate biomarkers of HGF/cMet pathway activation in tumor tissue, plasma, and immune cells.
Esophageal cancer is one of common malignant tumors in China and esophageal squamous cell carcinoma (ESCC) is the dominant pathological type, accounting for more than 95% of all cases. One of our phase Ⅱ study introduced a combination treatment of an anti epithelial growth factor receptor (EGFR) agent, nimotuzumab, with paclitaxel and cisplatin as first-line treatment in unresectable or metastatic ESCC. The results showed that the overall response rate was 51.8% (29/56) and disease control rate was 92.9% (52/56). As a median follow-up of 24 months, the median progression-free survival for patients with metastatic disease and local advanced disease were 8.2 months and more than 23 months respectively. The overall survival for patients with metastatic disease was 13.9 months. It implied that as first-line chemotherapy, an addition of nimotuzumab to chemotherapy was a more active treatment option compared to other regimens published in previous studies. Investigations by Liang, J. and Ling, Y. also suggested that nimotuzumab in combining with radiotherapy or chemotherapy also showed anti-tumor activities and limited toxicities. Therefore, we initiated this phase Ⅱ to Ⅲ clinical trial in which combining neoadjuvant treatments of nimotuzumab with chemotherapy or nimotuzumab with radiotherapy are compared with surgery alone for resectable stage Ⅱa to Ⅲ middle and lower thoracic esophageal squamous cell carcinoma patients. We hope to explore if these neoadjuvant combination treatments could bring survival benefit for ESCC patients.
The purpose of this research study is to look at the effect of a treatment regimen called CACTUX on head and neck cancer. The CACTUX regimen is a combination of three drugs called cisplatin, nab-paclitaxel, and cetuximab (although carboplatin may be given in place of cisplatin if participants have previously had problems receiving cisplatin). The use of nab-paclitaxel in this combination is different from routine care, in which a drug called 5FU is often given instead, but the investigators group has conducted previous research where the investigators incorporated nab-paclitaxel into routine treatment with cisplatin, 5FU, and cetuximab. The investigators are looking at the incidence of side effects with the CACTUX regimen as well as response of the disease and health status.
The main hypothesis of this study is that it is possible to make a unilateral selective dissection of ganglion levels IIa, III and IV using an endoscopic transaxillary approach via the da Vinci robotic system to reduce scarring, while respecting patient safety. Feasibility will be assessed by two combinded criteria: 1) performance of the surgical procedure respecting the different stages of visualization and dissection of key anatomical elements; 2) obtain a minimum of 9 lymph nodes when analyzing pathological evidence of the dissection.
This is an open label, monocentric, uncontrolled phase II trial with Dacomitinib, a pan-HER inhibitor, in unresectable or metastatic skin SCC. HER2 expression is common in skin SCC, being reported with high rates, even if in small studies. Coexpression of EGFR, HER2 and HER3 is present in skin SCCs but not in normal skin and it could be associated with the malignant phenotype. In this frame Dacomitinib could play a role in the increase of the response rate.
This is a multicenter, open-label, dose-exploration and dose-expansion study to evaluate the safety, tolerability, antitumor activity, PK, pharmacodynamics, and immunogenicity of MEDI4736 in combination with tremelimumab in subjects with recurrent/metastatic squamous cell carcinoma of the head and neck.
This phase II trial studies nab-paclitaxel (paclitaxel albumin-stabilized nanoparticle formulation) and carboplatin followed by response-based local therapy in treating patients with stage III or IV human papillomavirus (HPV)-related oropharyngeal cancer. Drugs used in chemotherapy, such as paclitaxel albumin-stabilized nanoparticle formulation, carboplatin, hydroxyurea, fluorouracil, paclitaxel, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them spreading. Radiation therapy uses high energy x rays to kill tumor cells. Giving nab-paclitaxel and carboplatin before chemoradiation may make the tumor smaller and reduce the amount of chemotherapy and radiation therapy needed. Assigning chemotherapy and radiation therapy based on response (response-based therapy) and giving patients who are responding well lower doses of treatment may help reduce the occurrence of side effects.
This is a study of single-agent pembrolizumab (MK-3475) in participants with recurrent and/or metastatic head and neck squamous cell carcinoma (HNSCC) who have progressed on platinum-based and cetuximab therapy. The primary study hypothesis is that pembrolizumab will provide a clinically meaningful objective response rate (ORR). With protocol amendment 05 (02-Jan-2018), once study participants have achieved the study objective or the study has ended, participants will be discontinued from this study and enrolled in an extension study to continue protocol-defined assessments and treatment.
This randomized phase II trial studies the side effects and how well modestly reduced-dose intensity-modulated radiation therapy (IMRT) with or without cisplatin works in treating patients with oropharyngeal cancer that has spread to other places in the body (advanced). Radiation therapy uses high energy x rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether IMRT is more effective with or without cisplatin in treating patients with oropharyngeal cancer.
