Active clinical trials for "Carcinoma, Squamous Cell"

The goal of this clinical trial is to test a new drug plus standard treatment compared with standard treatment alone in patients with advanced head and neck squamous cell carcinoma, esophageal squamous cell carcinoma, and cholangiocarcinoma. The main questions it aims to answer are: is the new drug plus standard treatment safe and tolerable is the new drug plus standard treatment more effective than standard treatment

This is a single-center, single-arm, phase 2 study to evaluate the efficacy and safety of camrelizumab in combination with cetuximab and chemotherapy as first-line for patients with relapsed/metastastic head and neck squamous cell carcinoma

To learn if it is effective to use advanced radiation treatment techniques (stereotactic radiation or "SBRT") to safely deliver a strong dose of radiation to your tumor in a shorter period of time than would typically be feasible with traditional methods.

This research study is evaluating effectiveness and safety of a combination of immunotherapy drug, pembrolizumab, with chemotherapy, as a possible treatment before and after surgery for squamous cell carcinoma of the head and neck (HNSCC). The combination of pembrolizumab and chemotherapy will be given prior to your surgery, while immunotherapy pembrolizumab will be continued for approximately 1 year after surgery. The names of the study drugs involved in this research study are: pembrolizumab (a type of immunotherapy) docetaxel (a type of chemotherapy) cisplatin (a type of chemotherapy) carboplatin (a type of chemotherapy)

In this study, 100 patients with resectable head and neck squamous cell carcinoma (oral squamous cell carcinoma and oropharyngeal squamous cell carcinoma) were enrolled, who were combined with tirelizumab, carboplatin and albumin-binding paclitaxel before and after surgery. Tumor tissues and paracancer tissues of patients were collected to observe the imaging and pathological changes before and after treatment. At the same time, clinical information of patients, such as pathological grade, stage, treatment, prognosis, serology, imaging, etc. were collected to evaluate the safety and feasibility of tirelizumab combined with carboplatin and albumin-binding paclitaxel for neoadjuvant therapy of resectable oral and oropharyngeal squamous cell carcinoma. This is a prospective, one-arm, phase II clinical study. Purpose Main purpose The efficacy of Tirelizumab combined with carboplatin and albumin-paclitaxel in neoadjuvant therapy for resectable head and neck squamous cell carcinoma was evaluated by calculating the major pathological response (MPR) rates in the experimental group. The severity of adverse events associated with neoadjuvant therapy will be graded according to NCI CTCAE (version 5.0) during the course of this study and during follow-up, the incidence of adverse events in the experimental and control groups will be compared, and the safety of neoadjuvant therapy with Tirelizumab combined with carboplatin and albumin-paclitaxel in resectable head and neck squamous cell carcinoma will be evaluated. Secondary Purpose One-year event survival rate and event-free survival (EFS) of enrolled patients were evaluated (five years); Pathological complete response rate (pCR) of enrolled patients was evaluated (5 years); pTR of enrolled patients was evaluated; Overall survival (OS) of enrolled patients was evaluated (5 years); Radiological response of enrolled patients was assessed; The rate of operation delay of enrolled patients was evaluated;

The peculiarity of anal cancers, with well-established radical chemoradiotherapy that allows tumor-neoantigen formation with platinum-based chemotherapy and radiotherapy with radio-sensitizing chemotherapy could create the perfect environment for immunotherapy in this setting, not only to increase the probability of pathological complete response (CCR) but also creating neoantigen exposure and immune-prevention to reduce the relapse after surgery. TIRANUS trial is a Phase II, single-arm, open-label, non randomized, non controlled recruiting treatment-naive localized squamous cell carcinoma of the anal canal and are candidates for radical chemoradiotherapy. The trial hypothesizes that the addition of immunotherapy (atezolizumab and tiragolumab) to standard chemoradiotherapy in localized squamous cell carcinoma of the anal canal may improve the CCR at the end of consolidation phase. The study will assess, as the primary endpoint, the CCR, defined as the percentage of patients who have achieved complete response (CR), disappearance of all target lesions and no presence of residual disease assessed by biopsy at the end of consolidation phase. Secondary objectives include survival, safety of the combination, patient reported quality of life, and a substudy of molecular biomarkers determined in tumor biopsy and blood samples. The main question[s] it aims to answer are: To determine the efficacy of atezolizumab plus tiragolumab concomitantly with chemoradiotherapy in patients with localized squamous cell carcinoma of the anal canal evaluating the clinical response to treatment. To evaluate safety of the intended treatment regimen and Health-related quality of life (HRQoL) in this treatment regimen All patients will receive atezolizumab plus tiragolumab for 2 cycles in concomitance with the 6 weeks of standard scheduled chemoradiotherapy. (cisplatin, 5-Fluorouracil and radiotherapy). After the concomitant phase, patients will enter a consolidation phase and will receive atezolizumab in combination with tiragolumab up to 24 weeks. Patients will discontinue treatment in case of confirmed progression, toxicity, patient criteria, or physician criteria.

This study is the first clinical study of Neoadjuvant and Adjuvant treatment of head and neck squamous cell carcinoma with drugs targeting EGFR signaling pathway combined with PD-1 inhibitors, which explores the new combination therapies urgently needed in clinical practice and lays a foundation for subsequent studies, with important scientific research significance and clinical value.

This is a single-arm, open, exploratory clinical study to evaluate the efficacy and safety of camrelizumab combined with chemotherapy for adjuvant treatment of nodal positive thoracic esophageal squamous cell carcinoma.

Retrospective studies suggested that the addition of thoracic concurrent chemoradiotherapy to systemic chemotherapy improved the survival and quality of life (QOL) of patients with metastatic esophageal squamous cell carcinoma (ESCC). However, no prospective study had been conducted to confirm these findings. Recently, immunotherapy targeting the PD-1/PD-L1 checkpoints combined with chemotherapy had been proved to significantly prolong the survival of those patients compared with chemotherapy alone. Moreover, anti-PD-1 combined with radiotherapy exerts a synergistic anti-tumor effect, which may further improve the combination efficacy. This randomized, phase II study aimed to evaluate the efficacy and safety of the chemotherapy and anti-PD-1 combined with concurrent chemoradiotherapy to primary tumor versus systemic therapy alone in stage IVB ESCC. Of note, non-regional lymph node metastasis only was the stratification factor in the random assignment.

This is a Phase 1 dose-escalation study of PRT3645, a Cyclin-dependent Kinase 4/6 (CDK4/6) inhibitor, in patients with advanced or metastatic solid tumors. The purpose of this study is to investigate the safety, tolerability, dose limiting toxicity, and to determine maximally tolerated dose and recommended phase 2 dose to be used in subsequent development of PRT3645.
