Active clinical trials for "Anus Neoplasms"

To determine the efficacy of reduced elective nodal radiation in anal cancer patients undergoing chemoradiation in reducing toxicity compared to standard nodal irradiation.

This phase II trial studies the side effects of chemotherapy and intensity modulated radiation therapy in treating patients with low-risk HIV-associated anal cancer, and nivolumab after standard of care chemotherapy and radiation therapy in treating patients with high-risk HIV-associated anal cancer. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, such as mitomycin, fluorouracil, and capecitabine, 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. Giving chemotherapy with radiation therapy may kill more tumor cells. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving nivolumab after standard of care chemotherapy and radiation therapy may help reduce the risk of the tumor coming back.

Phase II randomized study of the use of pre-and probiotics during the definitive treatment of chemotherapy-radiotherapy (Ch-RT) for patients with localized anal canal squamous cell cancer (ACSCC) with the objective of increasing the effectiveness of conventional treatment based on the assumptions of that there is a need for research that increases the cure rates of the definitive treatment of Ch-RT in the ACSCC; ACSCC is a virus-associated tumor in many cases and therefore potentially immunogenic; immunotherapy is a promising strategy in ACSCC; and that pre- and probiotics can stimulate the immune system through modulation of the intestinal microbiota, and improve oncological outcomes.

In this Phase 1/2 study, the investigators will conduct a safety and efficacy study of the combination of BMX-001 with standard radiation therapy (RT) and concurrent 5-fluorouracil (5FU)/mitomycin in newly diagnosed Anal Squamous Cell Carcinoma (ASCC) patients. The primary objectives are: Phase 1 - is to determine the maximum tolerated dose (MTD) of BMX-001 in ASCC patients receiving RT and concurrent 5FU/mitomycin chemotherapy.2. For phase II part: To examine the impact of BMX-001 on the overall acute ≥ grade 3 toxicity rate of the normal tissue including rectum, bladder, and skin in combination with RT and concurrent 5FU/mitomycin in treatment of newly diagnosed ASCC patients

This protocol aims to determine toxicity and efficacy of re-irradiation for patients with recurrences from anal cancers with dose-escalated pencil beam proton therapy either pre-operative for marginally resectable recurrences or as a definitive treatment strategy (un-resectable, operation declined etc.). The over-all aim is to improve local tumor control with acceptable side effects.

This study evaluates the feasibility of the combination of radiotherapy, chemotherapies (docetaxel, cisplatin and 5-fluorouracil) and spartalizumab (anti-PD-1 therapy) in patients with metastatic squamous cell anal carcinoma

This phase II trial studies how well lower-dose chemotherapy plus radiation (chemoradiation) therapy works in comparison to standard-dose chemoradiation in treating patients with early-stage anal cancer. Drugs used in chemotherapy, such as mitomycin, fluorouracil, and capecitabine, 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. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving chemotherapy with radiation therapy may kill more tumor cells. This study may help doctors find out if lower-dose chemoradiation is as effective and has fewer side effects than standard-dose chemoradiation, which is the usual approach for treatment of this cancer type.

Based on the overwhelming positive response to this survey and the large number of patients being treated with PD-1/PD-L1 therapy in the UPMC system, the investigators are proposing a trial that will randomize patients who have disease stability to stop treatment at 1 year or continue treatment until disease progression. The investigators anticipate that the results of this study will answer questions regarding the optimal duration of treatment. therapy.

A single center, open, single arm dose escalation phase I study to evaluate the safety, tolerability, and efficacy of HRYZ-T101 TCR-T cell for HPV18 positive advanced solid tumor. The study will investigate DLT of HRYZ-T101 TCR-T cell injection.

AI-061 is a co-formulation drug product (DP) consisting of 1:1 ratio mix of AI-025, an anti-PD-1 antibody, and ONC-392, an anti-CTLA-4 antibody. This is a dose escalation study to identify the maximum toxicity dose (MTD) or the recommended phase 2 dose (RP2D).
