In-home Intravesical Chemotherapy for the Treatment of Bladder Cancer, INVITE Trial

This phase Ib/II trial compares the safety, tolerability and acceptability of intravesical chemotherapy given at home to in-clinic administration in patients with non-muscle invasive bladder cancer. Chemotherapy drugs, such as bacillus Calmette-Guerin (BCG), gemcitabine, docetaxel, and mitomycin C, 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. Standard of care chemotherapy for non-invasive bladder cancer is usually given directly into the bladder through a catheter (intravesical). This process requires numerous visits and can be disruptive to the lives of patients and caregivers. Bringing cancer care to the patients with in-home intravesical therapy may help reduce the disruption to daily lives. In-home intravesical chemotherapy may be safe and tolerable and may also be preferable to in-clinic administration in patients with non-muscle invasive bladder cancer.

Wisconsin Ginseng for Decreasing Cancer Related Fatigue

This phase III trial compares the effect of Wisconsin ginseng (panax quinquefolius) to placebo in patients with cancer that suffer from significant fatigue. Fatigue is among the most challenging symptoms to manage in patients with cancer, both on or off active treatment. This symptom complex meaningfully contributes to psychosocial distress, healthcare costs, and it also interferes with the delivery of anticancer therapies. American ginseng (Western ginseng) appears to be a promising appearing agent for treating cancer related fatigue. Western ginseng may reduce cancer-related fatigue.

Surgical Resection of Latent Brain Tumors Prior to Recurrence

This clinical trial evaluates the side effects and possible benefits of operating on brain tumors prior to the tumor coming back (recurrence). Understanding when surgery is most useful to patients with brain tumors is important. Some patients may undergo chemotherapy or radiation but still have visible tumor remaining after treatment. The purpose of this research is to compare outcomes of those who have surgery after chemotherapy or radiation, but prior to tumor recurrence, to those who have surgery at a different time, or no surgery at all.

Adding Spatially Fractionated Radiation Therapy to Standard Palliative Radiation for Improving Disease-Related Symptoms in Patients With Unresectable Solid Tumors

This clinical trial evaluates whether adding spatially fractionated radiation therapy (SFRT) to standard palliative external beam radiation therapy (EBRT) improves disease-related symptoms in patients with solid tumors that cannot be removed by surgery (unresectable). SFRT, originally termed GRID therapy, is a radiation therapy technique designed to deliver a highly uneven dose of radiation to a tumor. This is achieved by using a grid-like pattern, where isolated regions receive high doses, while the spaces between experience significantly lower doses. This method allows for a greater total dose to be delivered to the tumor while potentially reducing damage to surrounding healthy tissues. EBRT is a type of radiation therapy that uses a machine to aim high-energy rays at the cancer from outside of the body. Adding SFRT to standard palliative EBRT may improve disease-related symptoms such as pain, difficulty breathing, bleeding, or difficulty swallowing in patients with unresectable solid tumors.

Biologically-Adapted, Dose-Escalated Radiotherapy for the Treatment of Ewing Sarcoma, BEAR Trial

This clinical trial evaluates the effect of radiotherapy doses based on tumor size and tumor-specific characteristics (biologically-adapted) in treating patients with Ewing sarcoma. Radiotherapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. Conventional radiotherapy uses minimal imaging support to determine the positioning of radiotherapy. Hypofractionated radiotherapy delivers higher doses of radiotherapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Dose-escalated radiotherapy uses doses that are higher than those used in conventional radiotherapy. Larger tumor sizes and other tumor-specific characteristics have been shown to be related to poorer outcomes. In addition, after dose-escalated radiotherapy, patients with larger tumors have demonstrated improved control of the disease at the primary tumor site. Giving biologically-adapted, dose-escalated radiotherapy may reduce the return of the cancer at the primary tumor site in patients with Ewing sarcoma with large tumors and other unfavorable characteristics. This clinical trial also evaluates the role of biomarkers in patients with Ewing sarcoma. Studying samples of blood and tumor tissue from patients with Ewing sarcoma in the laboratory may help doctors learn more about predicting the amount of disease and the likelihood of the cancer coming back.

HRX215, A First Generation MKK4 Inhibitor Drug, for the Treatment of Patients With Colorectal Liver Metastasis After Undergoing a Portal Vein Embolization

This phase IIb trial tests the effect of HRX215 in treating patients with colorectal cancer that has spread from where it first started to the liver (liver metastasis) after undergoing a portal vein embolization (PVE). Currently, surgery to remove the tumor (hepatectomy) remains the only potential treatment for cure. However, less than 30% of patients are considered resectable (can be removed by surgery) at the time of diagnosis. The risk of liver failure and other complications rise with larger areas liver that is removed during surgery. Therefore, the potential for surgery is determined by the amount of liver that will remain after resection. PVE is a standard strategy to increase the potential for resection. A PVE is a procedure that blocks the portal vein (a blood vessel that carries blood to the liver) to prevent flow of blood to the tumor. HRX215 targets and binds to MKK4, a protein found on liver cells plays a part in cellular growth and prevents liver repair and regrowth of cells and tissue. Blocking the activity of MKK4 may help prevent liver failure, protect liver cells and improve liver mass. Giving HRX215 after a PVE may help improve the rate of liver regrowth and increase the likelihood of hepatectomy in patients with colorectal liver metastasis.

Cemiplimab and Fianlimab Before Surgery for the Treatment of Stage IB-IIIB Non-Small Cell Lung Cancer

This phase II trial tests how well a fixed dose combination (FDC) of cemiplimab and fianlimab before surgery (neoadjuvant) works in treating patients with stage IB-IIIB non-small cell lung cancer (NSCLC). The current standard of care (SOC) for NSCLC is to give chemotherapy and immunotherapy before going to surgery to have the cancer removed (neoadjuvant therapy). Immunotherapy with monoclonal antibodies, such as cemiplimab and fianlimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving a FDC of cemiplimab and fianlimab before surgery may kill more tumor cells in treating patients with stage IB-IIIB NSCLC.

Understanding the Mechanisms of Clonal and Non-clonal Cytopenia Following CAR-T Therapy for Multiple Myeloma or CD19+ Lymphoproliferative Disorder (LPD)

This clinical trial evaluates the impact of preexisting and therapy-emergent germline and somatic variants on cytopenia in patients with multiple myeloma or CD19 positive lymphoproliferative disorder (LPD) following chimeric antigen receptor T-cell (CAR-T) therapy. The most common adverse event after CAR-T therapy is lower than normal blood cells (cytopenia) and up to one third of patients experience cytopenia that last longer than 30 days post-infusion. Germline and somatic variants are changes in genes found using cancer genomic tests. Cancer genetic/genomic testing is a series of tests that find specific changes in cancer cells or in blood deoxyribonucleic acid. Identifying gene mutations may help identify the risk of cytopenia in patients with multiple myeloma or CD19 positive LPD following CAR-T therapy.

Molecular Breast Imaging Guidance for Breast Biopsy for Patients With Breast Abnormalities

This clinical trial tests how well molecular breast imaging (MBI) works to guide the collection of a breast biopsy in patients with a breast abnormality. Currently, a biopsy is often guided by either ultrasound or mammography in order to ensure that a sample of the correct part of the breast is taken. Sometimes a lesion or part of the lesion cannot be seen on ultrasound or mammography, and, therefore, a biopsy guided with ultrasound or mammography may not be always be accurate. Studies have shown that high resolution MBI may have potential to improve the detection of some breast tumors. This trial uses a new high-resolution MBI system that may help perform a biopsy using MBI.

Daratumumab Maintenance Therapy for Improving Survival in Patients With Light Chain Amyloidosis, EMILIA Trial

This phase II trial compares shorter-duration versus longer-duration maintenance therapy with daratumumab for improving survival in patients who have received initial treatment with daratumumab for light chain (AL) amyloidosis. Maintenance therapy is treatment that is given to help keep cancer from coming back after it has disappeared following initial therapy. Daratumumab is in a class of medications called monoclonal antibodies. It binds to a protein called CD38, which is found on some types of immune cells and cancer cells, including myeloma cells. Daratumumab may block CD38 and help the immune system kill cancer cells. Daratumumab is commonly prescribed as initial treatment for patients with AL amyloidosis. However, it is not known what role daratumumab may play in the maintenance therapy period of patients with AL amyloidosis. This phase II trial compares shorter duration maintenance to longer duration maintenance for improving survival in patients with AL amyloidosis.

Modified Immune Cells (Autologous Dendritic Cells) and a Vaccine (Prevnar) Combined With Immune Checkpoint Inhibition After High-Dose External Beam Radiation Therapy in Treating Patients With Unresectable Liver Cancer

This early phase I trial studies the side effects of autologous dendritic cells and a vaccine called Prevnar in combination with immune checkpoint inhibition (with bevacizumab and atezolizumab or druvalumab) in treating patients liver cancer that cannot be removed by surgery (unresectable) after undergoing standard high-dose external beam radiotherapy. Autologous dendritic cells are immune cells generated from patients' own white blood cells that are grown in a special lab and trained to stimulate the immune system to destroy tumor cells. A pneumonia vaccine called Prevnar may also help stimulate the immune system. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. Immunotherapy with monoclonal antibodies, such as atezolizumab and durvalumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Giving autologous dendritic cells and Prevnar in combination with immune checkpoint inhibition after radiotherapy may be safe, and tolerable and may stimulate the body's own immune system to fight against the tumor in patients with unresectable liver cancer.

Metabolic Impact of Pancreatic Duct Decompression

This study is a pilot study evaluating the impact of clearing out the pancreatic duct in patients with chronic pancreatitis who have a blockage in their pancreatic duct. While we typically perform procedures with an endoscope (a long flexible tube with a camera that goes through the mouth to reach the small intestine) to relieve a pancreatic duct blockage in patients with chronic pancreatitis who have pain and have a blockage, we do not know how relieving this blockage improves pancreatic function. Therefore, we are performing a preliminary study where participants will be randomized to either receiving an endoscopy or not undergoing an endoscopy. This will provide some background data to help inform us whether we should perform a larger study in the future to answer this question.

Evaluation of Alternative Site Goserelin Acetate Injection for Ovarian Function Suppression (OFS) in Local and Locally Advanced Premenopausal Hormone Receptor Positive Breast Cancer Patients

This phase II trial determines if giving goserelin acetate injections in the upper gluteal region is as effective for ovarian function suppression (OFS) as giving injections in the abdomen for ovarian function suppression (OFS) in premenopausal patients with hormone receptor positive breast cancer that has not spread to other parts of the body (localized) or that has spread to nearby tissue or lymph nodes (locally advanced). Goserelin acetate is a drug used to treat prostate cancer, relieve the symptoms of advanced breast cancer, and treat problems with the endometrium (lining of the uterus). Goserelin acetate initially causes the pituitary gland to make more luteinizing hormone (LH) and follicle-stimulating hormone (FSH), temporarily increasing testosterone levels in men and estrogen levels in women. With continued use, goserelin acetate lowers the amount of LH and FSH the pituitary gland releases, leading to a drop in testosterone levels in men and estrogen levels in women. Goserelin acetate may stop the growth of cancer cells that need testosterone or estrogen to grow. It is a type of hormone therapy called a luteinizing hormone-releasing hormone (LHRH) agonist. Giving goserelin acetate injections in the upper gluteal region may be as effective for OFS as giving injections in the abdomen for OFS in premenopausal patients with localized or locally advanced hormone receptor positive breast cancer.
