Active clinical trials for "Carcinoma"

Background: Hepatocellular carcinoma (HCC) is the most common primary liver cancer with aggressive tumor behavior. Radiofrequency ablation (RFA) or microwave ablation (MWA) is an effective curative treatment for early stage HCC. This thermal ablation of liver tumor induces host immune response with changes in serum concentration of various cytokines. It is not clear whether this host immune response correlates with tumor recurrence and long-term patient survival. Objective: This prospective study is to investigate the change of cytokines' level following RFA or MWA for HCC and its clinical correlation with tumor recurrence and patients' long-term survival data. Hypothesis: Thermal ablation of HCC creates tumor antigen source for the generation of antitumor immunity and enhances host immune responses. The resulting inflammation and changes in cytokines may augment tumor cell death by increasing neutrophil infiltration and oxidative burst mechanisms. On the other hand, there may be negative effects via the production of growth factors, which could stimulate tumor cell growth within the sub-lethal margin. Therefore, the ultimate clinical consequences would be significantly affected by these immune responses. Study design: This is a prospective study on the measurement of changes of serum cytokines in patients with HCC undergone RFA or MWA using the commercially available kit (MILLIPEX, Human cytokine/chemokine magnetic bead panel - Immunology Multiplex Assay ), which measure 10 cytokines, including IL-1β, IL-6, IL-10, IL-12 (p40), IL-12 (p70), TNF-α, CXCL8, CXCL9, CXCL10, CCL2, CCL5. Statistical correlation will be performed between the cytokine change and long-term patients' clinical outcome using the prospectively collected database. Subjects: Patients with HCC undergone RFA or MWA in the Department of Surgery, The Chinese University of Hong Kong will be recruited. Exclusion criteria were evidence of extrahepatic metastasis, patients receiving combined hepatectomy and other local ablative therapy and patients with decompensated liver function that preclude local ablative treatment. Intervention: RFA or MWA will be performed for patients with HCC. The serum samples of all consecutive recruited patients will be collected prospectively during the intervention. The measurement of cytokines level will be performed in the Laboratory of Department of Chemical Pathology, The Chinese University of Hong Kong under the standard protocol. Main outcome measures: Primary outcome measure is early intrahepatic tumor recurrence within one year after thermal ablation. Secondary outcome measures are other tumor recurrence pattern (late intrahepatic recurrence and extrahepatic metastasis), overall survival and recurrence-free survival. Data analysis: All data will be prospectively collected by a research assistant and computerized in a database. Statistical analysis will be performed by Chi-square test or Fisher's exact test, where appropriate, to compare discrete variables and Mann-Whitney U test to compare continuous variables. Cumulative survival will be computed by the Kaplan-Meier method and compared by Log-rank test. Multivariable analysis using logistic regression model will be done to identify the independent prognostic factors affecting early tumor recurrence. Expected results: Understanding the relationship between the cytokines change during thermal ablation and post-treatment tumor recurrence helps to identify high risk patients for the possible adjuvant therapy in future study.

This trial will explore effectiveness and safety using the combination therapy of camrelizumab，apatinib and hyperfractionated radiotherapy in patients with renal cell carcinoma(RCC). Hypofractionation is a technique that delivers higher daily doses of radiation over a shorter period of time.immunotherapy. hyperfractionated radiotherapy, represented by stereotactic body radiation therapy (SBRT), can significantly improve the radiotherapy sensitivity of RCC. This trial will also observe whether SBRT can bring about immune effects and explore the group and individual indicators that affect the treatment effect of RCC.

This is a phase I/Ib, first-in-human (FIH), open-label, dose escalation and dose expansion study to evaluate the safety and tolerability, biological and clinical activities of GEN-001 in patients with locally advanced or metastatic solid tumors who have progressed on at least two lines of approved therapy for their histological subtypes which includes an anti-PD-1 or anti-PD-L1 based therapy (as mono or combination), when administered as combined with avelumab.

This phase I/II trial studies the side effects and how well bintrafusp alfa and stereotactic body radiation therapy work in treating patients with head and neck squamous cell cancer that has come back (recurrent) or has occurred after having cancer in the past (second primary). Immunotherapy with bintrafusp alfa may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method can kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Giving bintrafusp alfa and stereotactic body radiation therapy may help to control recurrent head and neck squamous cell cancer.

The purpose of this study is to assess the efficacy and safety of intratumoral (IT) ulevostinag in PLUS pembrolizumab (MK-3475) compared to pembrolizumab alone as a first line treatment of adults with metastatic or unresectable, recurrent head and neck squamous cell carcinoma (HNSCC). The primary study hypotheses are that IT ulevostinag in combination with pembrolizumab results in a superior Objective Response Rate (ORR), per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1), compared to pembrolizumab alone: in participants with a tumor that has a programmed cell death-ligand 1 (PD-L1) Combined Positive Scoring (CPS) ≥ 1, and in participants with a tumor that has a PD-L1 CPS ≥ 20.

This study will evaluate the safety, tolerability, pharmacokinetic and efficacy of fisogatinib (formerly known as BLU-554) in combination with CS1001 in patients with locally advanced or metastatic hepatocellular carcinoma (HCC)

For recurrent or persistent advanced cervical cancer patients, the first-line chemotherapy was based on platinum. However, if they were refractory to platinum-based chemotherapy, there were no other more effective medications or treatment. The marketing of anti-PD-1 antibody has provided an opportunity of curative management. This single arm, open, phase II trial would recruit 34 eligible patients. A combination of anti-PD-1 antibody camrelizumab and albumin-bound paclitaxel would be given for first 9 patients. If at least total 2 patients achieved complete or partial remission, or at least total 6 patients achieved complete or partial remission or stable disease, the same regimen would be given for rest patients. The primary end is overall response rate (ORR). The second ends include progression-free survival, overall survival, disease control rate, remission duration, and adverse events. A molecular testing, mainly consisting of genomic analysis, will be carried in the oncologic tissues.

This is a prospective clinical study aiming to tests the safety and efficacy of lenvatinib in combination with gefitinib in people with lenvatinib resistant hepatocellular carcinoma. This study will help find out if lenvatinib and gefitinib is a safe and useful combination for treating patients with lenvatinib resistant hepatocellular carcinoma.

This is a Phase Ib study to evaluate the safety, tolerability and efficacy of Sintilimab combined with IBI305 in patients with advanced hepatocellular carcinoma in China.

This is a Phase I dose-escalation study of sEphB4-HSA in combination with chemotherapy, cetuximab and radiotherapy (RT). The purpose is to estimate the maximum tolerated dose (MTD) that can be administered concurrently with Cetuximab and radiation in patients with locally advanced, Stage III or IV A-B squamous cell carcinomas of the head or neck with a history of at least ten pack-years of smoking.
