Talimogene Laherparepvec and Nivolumab in Treating Patients With Refractory Lymphomas or Advanced or Refractory Non-melanoma Skin Cancers

This phase II trial studies how well talimogene laherparepvec and nivolumab work in treating patients with lymphomas that do not responded to treatment (refractory) or non-melanoma skin cancers that have spread to other places in the body (advanced) or do not responded to treatment. Biological therapies, such as talimogene laherparepvec, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop tumor cells from growing. 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 talimogene laherparepvec and nivolumab may work better compared to usual treatments in treating patients with lymphomas or non-melanoma skin cancers.

ASTX727 & Retifanlimab-dlwr for Advanced Merkel Cell After Progression on Anti-PD-(L)1

The goal of this clinical trial is to learn if ASTX727 can be combined with retifanlimab to treat Merkel cell cancer. It will also learn about the safety of combining these drugs. The main questions it aims to answer are: * Can the combination shrink cancer and lower the chance of the cancer growing or spreading? * Is the combination better than standard of care for Merkel cell cancer? Participants will: * Take oral ASTX727 and retifanlimab through a vein in the arm for about 2 years. * Visit the clinic once every 2 weeks for checkups and tests

Randomized Study of Nivolumab+Ipilimumab+/- SBRT for Metastatic Merkel Cell Carcinoma

The purpose of this study is to test the effectiveness, safety, and tolerability of the drugs nivolumab plus ipilimumab with or without the addition of stereotactic body radiation therapy (SBRT). Nivolumab is an antibody (a type of human protein) that is being tested to see if it will stimulate the body's immune system to work against tumor cells. This study will test an investigational use of nivolumab.

EMLA Topical Cream for Treatment of Pain in Patients Receiving Intra-Dermal Technetium 99 Injections for Lymphoscintigraphy for Skin Cancers

This phase II trial tests how well EMLA topical cream works in treating pain in patients with skin cancers receiving Technetium 99 injections for a lymphoscintigraphy mapping procedure. A lymphoscintigraphy mapping procedure is used to find the main or lead lymph node (tissue that fight infection) so it can be removed and checked for tumor cells. Using lymphoscintigraphy to highlight and then surgically remove lymph nodes is standard way to treat skin cancer for many patients. The Technetium 99 injections used for lymphoscintigraphy can be briefly painful due to the sensitivity of the nerve endings in the skin. The EMLA topical cream, which contains a numbing medicine to block pain from nerve endings, has been studied in breast cancer patients with a difference in pain reported, but this is the first time it has been studied in patients undergoing lymphoscintigraphy for skin cancer. This study may help researchers learn whether the use of EMLA cream may improve the associated pain at the time of the lymphoscintigraphy procedure.

Study to Investigate the Efficacy and Safety of RP1 in Adult Patients With Organ Transplants and Advanced Skin Malignancies

The purpose of this study is to assess the safety and efficacy of RP1 (administered into the tumor) in 90 patients who have received an organ transplant in the past and currently have skin cancer. The skin cancer is either locally advanced (large tumors in the skin, muscles or nerves) or metastatic (spread to other parts of the body). This study will consist of a 28-day Screening Period, a Treatment Period, and a Follow-up Period. During the Treatment Period, patients will be dosed with RP1 every two weeks for up to 2 years (104 weeks). Tumor measurements will be done approximately every 8 weeks (and additionally if needed) until progressive disease, start of subsequent anticancer therapy, or completion/discontinuation of the study. During the Follow-up Period, patients will visit the clinic at 30, 60, and 100-150 days after their last dose of RP1 for safety and quality of life assessments. Patients will continue follow-up for up to 3 years from the day of the last patient's first dose.

Triple Immune Checkpoint Inhibition for Advanced or Metastatic PD-(L)1 Refractory Merkel Cell Carcinoma

This phase II trial tests how well a combination of three immunotherapy drugs work for patients with Merkel cell carcinoma that has spread to lymph nodes and/or distant parts of the body and cannot be treated with surgery (advanced or metastatic MCC) and grew despite prior PD-(L)1 therapy. The three drugs INCMGA00012 (retifanlimab, anti-PD-1), INCAGN02385 (tuparstobart, anti-LAG-3), and INCAGN02390 (verzistobart, anti-TIM-3) are monoclonal antibodies given periodically via IV to reactivate the body's immune system to attack the cancer. This combination may stop tumor growth if tumors have grown despite anti-PD-(L)1 therapy alone.

Hypofractionated Radiation Therapy for Merkel Cell Carcinoma

This phase II trial tests whether hypofractionated radiation works to treat patients with Merkel cell carcinoma. Radiation therapy uses high energy radio waves to kill cancer cells and shrink tumors. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may be more convenient for patients and less immunosuppressive.

QUILT-3.055: A Study of Combination Immunotherapies in Patients Who Have Previously Received Treatment With Immune Checkpoint Inhibitors

QUILT-3.055 is a Phase 2b, open-label, multicohort study investigating combination immunotherapies in patients with advanced solid tumors who have previously been treated with PD-1/PD-L1 checkpoint inhibitors. The study aims to evaluate the safety and efficacy of NAI (nogapendekin alfa inbakicept) in combination with other agents like checkpoint inhibitors and cell therapies across various cancer types and treatment settings. The study includes multiple cohorts based on prior therapies and cancer types, with a focus on assessing overall response rate (ORR), overall survival (OS), and other measures of anti-tumor activity and immune response.

In Situ Immunomodulation With CDX-301, Radiation Therapy, CDX-1140 and Poly-ICLC in Patients w/ Unresectable and Metastatic Solid Tumors

This phase I trial evaluates the safety and effectiveness of in situ immunomodulation with CDX-301, radiotherapy, CDX-1140 and Poly-ICLC (Cohort A) and these with intravenous (IV) pembrolizumab and subcutaneous (SC) tocilizumab (Cohort B) in treating patients with unresectable and measurable metastatic melanoma, cutaneous squamous cell carcinoma (SCC), basal cell carcinoma (BCC), Merkel cell carcinoma, high-grade bone and soft tissue sarcoma or HER2/neu(-) breast cancer. CDX-301 may induce cross-presenting dendritic cells, master regulators in the immune system. Radiation therapy uses high energy to kill tumor cells and release antigens that may be picked up, processed and presented by cross-presenting dendritic cells. CDX-1140 and Poly-ICLC may activate tumor antigen-loaded,cross-presenting dendritic cells, and generate tumor-specific T lymphocytes, a type of immune cells, that can search out and attack cancers. Giving immune modulators and radiation therapy may stimulate tumor cell death and activate the immune system.

The Cancer Connected Access and Remote Expertise Beyond Walls Program to Provide In-Home Cancer Treatment and Improve Treatment Satisfaction in Cancer Patients Living in the Florida Panhandle and Surrounding Areas

This phase II trial studies whether providing cancer treatment in the home is preferred over the traditional clinic setting and if it improves treatment satisfaction in cancer patients living in the Florida Panhandle and surrounding areas. Typically, drug-related cancer care is provided at a medical center which causes patients to have to spend considerable time away from their family, friends, and familiar surroundings. This may add to the physical, emotional, social, and financial burden for patients and their families during this difficult time in their lives. The Cancer Connected Access and Remote Expertise (CARE) Beyond Walls (CCBW) program uses a specialized care team trained to provide cancer treatment in the patient's home setting. It is designed to support remote connection between the home health team and providers and Mayo clinic. This may be preferred over the traditional clinic setting which may improve treatment satisfaction in cancer patients living in the Florida Panhandle and surrounding areas.
