Active clinical trials for "Neoplasms"

This is an open-label, randomized, controlled, multicenter, phase III study with two parallel arms. Patients with metastatic colorectal cancer after definite interventional therapy of all lesions are randomized in a 2:1 fashion (favoring active therapy) to investigate the efficacy, patient reported quality of life and safety of mFOLFOXIRI/mFOLFOX-6 as additive treatment (Arm A) versus active follow-up/surveillance (Arm B).

This phase I/II study was designed to evaluate the efficacy and safety of fruquintinib combination with capecitabine in maintenance treatment after first-line chemotherapy combined with cetuximab.

According to the BCLC staging system treatment recommendation, systemic treatment is recommended for patients in BCLC stage C, and TACE and systemic treatment are recommended for patients in this stage. Studies have shown that TACE combined with sorafenib therapy has shown effectiveness in the treatment of advanced liver cancer, and PD-1 inhibitors have also shown effectiveness in the treatment of advanced liver cancer. Therefore, in order to improve the survival benefit of BCLC stage C liver cancer patients, this clinical study was designed to evaluate the effectiveness and safety of TACE combined with sorafenib and tislelizumab in the treatment of BCLC stage C liver cancer patients.

For locally advanced adenocarcinoma of esophagogastric junction(AEG) (cT3-4aN+M0), neoadjuvant chemotherapy was improved to downstage T and N stage, increase the resectability of tumor, and finally improve the long-term survival. Combination of perioperative PD-1 antibody and chemotherapy for locally advanced AEG could be a novel therapy to increase response rate and resectability and reduce recurrence rate. Sintilimab in this study is an anti-PD-1 monoclonal antibody for injection which has been approved for several malignant tumors. This study is a multi-center, open-label, randomized phase II clinical trial to evaluate tolerability, safety and efficacy of sintilimab in combination with perioperative chemotherapy in locally advanced AEG.

The purpose of the study is to explore adding the study drug certolizumab to standard chemotherapy as it may reduce the inflammation caused by the cancer and make the chemotherapy more effective in shrinking the cancer. This study will examine whether adding certolizumab to the usual treatment approach is better than, the same as, or worse than the usual approach alone.

In this study, locally advanced rectal cancer (LARC) patients with lateral lymph node (LLN) metastasis would be enrolled. The LLNs with short axis (SA) ≥ 5 mm are considered metastatic.The safety of neoadjuvant chemoradiotherapy(nCRT) with a booster dose to 58Gy had been initially demonstrated in our previous research. The effective and safety of dose escalation of LLN in LARC patients, will be further verified in this prospective, clinical study.

This study will test the safety and efficacy of intra-arterial chemotherapy in subjects with newly diagnosed, residual, or recurrent atypical choroid plexus papilloma and choroid plexus carcinoma prior to a second surgery. It is believed that intra-arterial chemotherapy will be safe and feasible for this population and will result in decreased tumor size, which may further improve the goals of a second-look surgery.

The purpose of this study is to learn whether it is safe to give HER2-CAR T cells in combination with an immune checkpoint inhibitor drug (pembrolizumab or nivolumab), to learn what the side effects are, and to see whether this therapy might help patients with sarcoma. Another goal of this study is to study the bacteria found in the stool of patients with sarcoma who are being treated with HER2 CAR T cells and immune checkpoint inhibitor drugs to see if the types of bacteria influence how well the treatment works. The investigators have found from previous research that they can put a new gene into T cells that will make them recognize cancer cells and kill them. They now want to see if they can put a new gene in these cells that will let the T cells recognize and kill sarcoma cells. The new gene that the investigators will put in makes an antibody specific for HER2 (Human Epidermal Growth Factor Receptor 2) that binds to sarcoma cells. In addition, it contains CD28, which stimulated T cells and make them last longer. After this new gene is put into the T cell, the T cell becomes known as a chimeric antigen receptor T cell or CAR T cell. In another clinical study using these CAR T cells targeting HER2 as well as other studies using CAR T cells, investigators found that giving chemotherapy before the T cell infusion can improve the effect the T cells can have. Giving chemotherapy before a T cell infusion is called lymphodepletion since the chemotherapy is specifically chosen to decrease the number of lymphocytes in the body. Decreasing the number of the patient's lymphocytes first should allow the infused T cells to expand in the body, and potentially kill cancer cells more effectively. The chemotherapy used for lymphodepletion is a combination of cyclophosphamide and fludarabine. After the patient receives the lymphodepletion chemotherapy and CAR T cells during treatment on the study, they will receive an antibody drug called an immune checkpoint inhibitor, pembrolizumab or nivolumab. Immune checkpoint inhibitors are drugs that remove the brakes on the immune system to allow it to act against cancer.

Recent studies suggest that patients with metastatic melanoma whose gut microbiome is colonized by eubiotic bacteria have a stronger anti-cancer response to anti CTLA-4 and anti PD1. The hypothesis of this research is that a pooled standardized fecal microbiome transfer (FMT) will shift melanoma patients' gut microbiome towards a composition close to that associated with a better response, and will therefore increase the response to a combination of anti CTLA-4 and anti PD1, without affecting the safety of these drugs. The present trial is the first randomized trial of FMT in patients with unresectable or metastatic melanoma. It will include patients who have neither been exposed to anti CTLA-4 nor anti PD1 or PDL-1, prior to inclusion in the study. The pooled standardized fecal microbiome transfer administered in this study is an experimental drug MaaT013, a microbiome restoration biotherapeutic, produced by MaaT Pharma, and composed of pooled-donor, full-ecosystem intestinal microbiome. The MaaT013 product has a standardized richness (in number of species present) higher than a product obtained from a mono donor (455 species approximately against 274 on average) and contains bacteria species (mentioned in the rationale) associated with better response to anti- CTLA-4 and anti PD1.

Adding chemotherapy or anti-VEGF to immunotherapy is an emerging strategy to enhance the efficacy of immunotherapy in many cancers. This phase 2 study aims to explore the preliminary efficacy of combination pembrolizumab with lenvatinib and chemotherapy in NSCLC patients with sensitizing EGFR, ALK, or ROS1 genetic aberration refractory to standard targeted therapy.
