Filter by:Radiotherapy for advanced-stage head and neck squamous cell carcinoma (HNSCC) results in an unfavorable 5-year overall survival of 40%, and there is a strong biological rationale for improving outcome by combinatorial treatment with immunotherapy. However, also immunosuppressive effects of radiotherapy have been reported and recently a randomized phase-III trial failed to show any survival benefit following the combination of a PD-L1 inhibitor with chemoradiotherapy. The hypothesis is that the combination of these individually effective treatments failed because of radiation-induced lymphodepletion and that the key therefore lies in reforming conventional radiotherapy, which typically consists of large lymphotoxic radiation fields of 35 fractions. By integrating modern radiobiology and individually established innovative radiotherapy concepts, the patient's immune system could be maximally retained. This will be achieved by 1) increasing the radiation dose per fraction so that the total number of fractions can be reduced (HYpofractionation), 2) by redistributing the radiation dose towards a higher peak dose within the tumor center and a lowered elective-field dose (Dose-redistribution) and 3) by using RAdiotherapy with protons instead of photons (HYDRA). The objectives of this study are to determine the safety of HYDRA with protons and photons by conducting two parallel phase-I trials. HYDRA's efficacy will be compared to standard of care (SOC). The immune effects of HYDRA-protons will be evaluated by longitudinal immune profiling and compared to HYDRA-photons and SOC (with protons and photons). There will be a specific focus on actionable immune targets and their temporal patterns that can be tested in future hypofractionated-immunotherapy combination trials. This trial therefore is an important step towards future personalized immuno-radiotherapy combinations with the ultimate goal to improve survival for patients with HNSCC.
Neoadjuvant chemoradiotherapy followed by surgery has been the standard modality for locally advance esophageal carcinoma. According to CROSS study, the pathological complete remission rate achieved by paclitaxel and carboplatin with 41.4 Gy/23f was 49% for esophageal squamous cell carcinoma. But the 10-year overall survival rate was only 38%. How to increase the overall survival of esophageal carcinoma is a pivotal task. Both of Camrelizumab and Nimotuzumab have been demonstrated to be efficacious in the neoadjuvant treatment for esophageal squamous cell carcinoma in some small sample-size trials. Therefore, this trial is designed to combine adjuvant chemoradiotherapy with Camrelizumab and Nimotuzumab for resectable & potentially resectable locally advanced esophageal squamous cell carcinoma and explore the safety and primary efficacy of such combination.
This is an open-label, single-arm, phase II clinical trial to explore the efficacy and safety of neoadjuvant low-dose radiotherapy combined with chemoimmunotherapy in resectable locally advanced head and neck squamous cell carcinoma. The eligible patients are scheduled to administered neoadjuvant low-dose radiotherapy, tislelizumab, combined with albumin-bound paclitaxel and cisplatin for two cycles. Radical resection will be performed in 3-4 weeks after two cycles of neoadjuvant therapy. The overall primary study hypothesis is that the novel neoadjuvant combination regime improves the pathological complete response (pCR) rate, with tolerable side effects.

Phase II, open label, multicentric, proof-of-principle basket trial in patients with malignant tumors of the skin amenable to intratumoral injection, and in a curative or neoadjuvant or palliative intention.
Due to the scarcity of data on prognostic and predictive influence on CCA, epidemiological studies evaluating these factors need to be developed in patients with CCA. Therefore, the investigators want to evaluate the profile of patients in the real world and from various parts of the world, describing prognostic factors such as CD4 dosage, time of HIV infection, evaluation of viral load, diagnosis of AIDS, geographic region of diagnosis and treatment, clinical staging, medications concomitant with QRT (risk of drug interactions), comorbidities (possible impact on dose-intensity), use of HAART, time of use of HAART, radiotherapy modality (conventional 3D vs Modulated Beam Intensity [IMRT], response to Nigro vs CTII regimens, as well as comparing clinical outcomes with patients without HIV infection.
This project aims to organise the sampling of blood and tumor at key points of the standard of care of patients with recurrent or metastatic squamous-cell carcinoma of the head and neck (HNSCC). This will allow to identify new potential predictive biomarkers of efficacy of immunotherapy and to investigate the evolution of the tumoral microenvironment after successive systemic treatments.
This study aimed to evaluate the safety and feasibility of neoadjuvant tislelizumab combined with chemoradiotherapy in patients with resectable esophageal squamous cell cancer. The tumor microenvironment and circulating immunological biomarkers in these patients were further evaluated to explore the factors affecting the efficacy of neoadjuvant therapy for esophageal cancer. This study will provide valuable information for further prospective clinical trials of neoadjuvant anti-PD-1 and other immunotherapy in esophageal cancer patients.
This is a multi-center clinical study enrolling up to 86 participants. The primary objectives are to determine the objective response rate (ORR) established by the confirmed best overall response (BOR) following intratumoral administration of DaRT - Diffusing Alpha-Emitters Radiation Therapy, as well as to assess the Duration of Response (DOR) 6 months from initial response. Secondary objectives are to assess the safety of DaRT, and to assess the progression free survival (PFS), overall survival (OS), Overall Duration of Response (O-DOR), local control and quality of life (QOL) for patients treated with DaRT.
This phase I/II trial studies the side effects of tozuleristide in imaging oral cavity squamous cell cancer and high-grade oral cavity dysplasia during surgery. Tozuleristide is an imaging agent that specifically binds to tumor cells. When exposed to near-infrared light, tozuleristide causes tumor cells to fluoresce (light up), so that surgeons may better distinguish tumor cells from healthy cells during surgery.
