A Study of SGN-B6A Versus Docetaxel in Previously Treated Non-small Cell Lung Cancer

Carcinoma, Non-Small-Cell Lung

This clinical trial is studying nonsquamous non-small cell lung cancer (NSCLC). Participants in this study must have cancer that has spread through their body or can't be removed with surgery. Participants in this study must have been treated with no more than a platinum-based chemotherapy and an anti-PD-(L)1 drug. Participants with tumors that have certain treatable genomic alterations must have had at least 1 drug for that genomic alteration, in addition to platinum-based chemotherapy. This clinical trial uses an experimental drug called sigvotatug vedotin, which is a type of antibody drug conjugate or ADC. ADCs are designed to stick to cancer cells and kill them. This clinical trial also uses a drug called docetaxel. Docetaxel is an anticancer drug that has been approved to treat non-small cell lung cancer. It is usually given to patients who previously received another anticancer treatment. In this study, one group of participants will get sigvotatug vedotin on Days 1 and 15 during each 28-day-cycle. A second group of participants will get docetaxel on Day 1 during each 21-day cycle. This study is being done to see if sigvotatug vedotin works better than docetaxel to treat participants with NSCLC. This study will also test what side effects happen when participants take these drugs. A side effect is anything a drug does to the body besides treating the disease.

Vepdegestrant (ARV-471/PF-07850327) + Palbociclib vs Letrozole + Palbociclib in ER(+)/HER2(-) Advanced Breast Cancer

Breast Cancer

The purpose of this study is to understand the safety and effects of the study medicine vepdegestrant (ARV-471/PF-07850327) given together with palbociclib in advanced breast cancer. In particular, the study will compare the combination of vepdegestrant plus palbociclib to standard of care therapy (letrozole plus palbociclib). Both letrozole and palbociclib are medicines already used for treatment of breast cancer. Vepdegestrant is a new medicine under study. This study is seeking participants who have breast cancer that: * Have a locally advanced or metastatic disease and cannot be fully cured by surgery or radiation therapy. A metastatic disease is when disease has spread to other parts of the body. * Is sensitive to hormonal therapy such as tamoxifen. This is called estrogen receptor positive disease. * Have not received any prior medicine for advanced disease. Example medications include tamoxifen or letrozole or exemestane. The study will have an open-label SLI (study lead-in) before initiation of Phase 3 trial. During SLI, two dose levels of palbociclib in combination with vepdegestrant will be explored in parallel. Assignment to the palbociclib dose is by chance. Half of the participant will receive one dose and the other half another palbociclib dose. The purpose of SLI is to determine the recommended Phase 3 dose of palbociclib to be administered in combination with vepdegestrant. In the Phase 3, half of the participants will take vepdegestrant plus palbociclib while the other half will take letrozole plus palbociclib. In both SLI and Phase 3, participants will take the study medicines by mouth, with food, once a day. Participants will take the study medicines until breast cancer increase in size or side effects become too severe. Side effects refer to unwanted reactions to medications. Participants will visit the study clinic about once every 4 weeks.

TTI-622 in Combination With Pembrolizumab for the Treatment of Relapsed or Refractory Diffuse Large B-Cell Lymphoma

Recurrent ALK Positive Large B-Cell Lymphoma Recurrent B-Cell Non-Hodgkin Lymphoma Recurrent Diffuse Large B-Cell Lymphoma Associated With Chronic Inflammation Recurrent Diffuse Large B-Cell Lymphoma, Not Otherwise Specified +24

This phase II trial tests the safety, side effects, and best dose of TTI-621 (closed to enrollment) or TTI-622 in combination with pembrolizumab in treating patients with diffuse large B-cell lymphoma that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory). TTI-621 and TTI-622 are called fusion proteins. A fusion protein includes two specialized proteins that are joined together. In TTI-621 and TTI-622, one of the proteins binds with other proteins found on the surface of certain cells that are part of the immune system. The other protein targets and blocks a protein called CD47. CD47 is present on cancer cells and is used by those cells to hide from the body's immune system. By blocking CD47, TTI-621 and TTI-622 may help the immune system find and destroy cancer cells. Pembrolizumab is a monoclonal antibody directed against human cell surface receptor PD-1 (programmed death-1 or programmed cell death-1) that works by helping the body\'s immune system attack the cancer and may interfere with the ability of cancer cells to grow and spread. Giving TTI-621 (closed to enrollment) or TTI-622 in combination with pembrolizumab may kill more cancer cells in patients with relapsed or refractory diffuse large B-cell lymphoma.

Testing the Safety of the Anti-cancer Drugs Tazemetostat and Belinostat in Patients With Lymphomas That Have Resisted Treatment

Recurrent B-Cell Non-Hodgkin Lymphoma Recurrent Diffuse Large B-Cell Lymphoma Germinal Center B-Cell Type Recurrent Follicular Lymphoma Recurrent Non-Hodgkin Lymphoma +10

This phase I trial tests the safety, side effects, and best dose of combination therapy with tazemetostat and belinostat in treating patients with lymphoma that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory). Tazemetostat is in a class of medications called EZH2 inhibitors. The EZH2 gene provides instructions for making a type of enzyme called histone methyltransferase which is involved in gene expression and cell division. Blocking EZH2 may help keep cancer cells from growing. Belinostat is in a class of medications called histone deacetylase inhibitors. Histone deacetylases are enzymes needed for cell division. Belinostat may kill cancer cells by blocking histone deacetylase. It may also prevent the growth of new blood vessels that tumors need to grow and may help make cancer cells easier to kill with other anticancer drugs. There is some evidence in animals and in living human cells that combination therapy with tazemetostat and belinostat can shrink or stabilize cancer, but it is not known whether this will happen in people. This trial may help doctors learn more about treatment of patients with relapsed or refractory lymphoma.

Testing the Addition of the Anti-cancer Drug, Cabozantinib, to the Usual Immunotherapy Treatment, Avelumab, in Patients With Metastatic Urothelial Cancer, MAIN-CAV Study

Advanced Bladder Urothelial Carcinoma Advanced Renal Pelvis Urothelial Carcinoma Advanced Ureter Urothelial Carcinoma Advanced Urethral Urothelial Carcinoma +14

This phase III trial compares the effect of adding cabozantinib to avelumab versus avelumab alone in treating patients with urothelial cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib and avelumab together may further shrink the cancer or prevent it from returning/progressing.

A Study to Test How BI 765063 and BI 770371 Are Taken up in Tumours of People With Different Types of Advanced Cancer Who Are Also Taking Ezabenlimab

Carcinoma, Squamous Cell of Head and Neck (HNSCC) Melanoma Non-small Cell Lung Cancer (NSCLC)

This study is open to adults with advanced head and neck cancer, skin cancer, or non-small cell lung cancer. People can take part if previous treatments were not successful. The purpose of this study is to find out how 2 medicines called BI 765063 and BI 770371 are taken up in the tumours and how they get distributed in the body. In addition to BI 765063 or BI 770371, participants also receive ezabenlimab. BI 765063, BI 770371 and ezabenlimab are antibodies that may help the immune system fight cancer. Such therapies are also called immune checkpoint inhibitors. Participants get either BI 765063 or BI 770371 in combination with ezabenlimab as an infusion into a vein every 3 weeks. In the first weeks, doctors check how BI 765063 and BI 770371 are taken up in tumours. To do so, the doctors use imaging methods (PET/CT scans). For this, participants get BI 765063 or BI 770371 injected in a labelled form up to 2 times. Participants can stay in the study as long as they benefit from treatment and can tolerate it. The doctors regularly check participants' health and take note of any unwanted effects.

Nivolumab in Combination With Chemo-Immunotherapy for the Treatment of Newly Diagnosed Primary Mediastinal B-Cell Lymphoma

Primary Mediastinal Large B-Cell Lymphoma

This phase III trial compares the effects of nivolumab with chemo-immunotherapy versus chemo-immunotherapy alone in treating patients with newly diagnosed primary mediastinal B-cell lymphoma (PMBCL). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of cancer cells to grow and spread. Treatment for PMBCL involves chemotherapy combined with an immunotherapy called rituximab. Chemotherapy drugs work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Giving nivolumab with chemo-immunotherapy may help treat patients with PMBCL.

RADIANT: A Study of Radium-223 Dichloride (Xofigo) vs Enzalutamide or Abiraterone (ARPIs, Androgen Receptor Pathway Inhibitors) in Patients With Prostate Cancer That Has Spread to the Bones (mCRPC, Metastatic Castration-Resistant Prostate Cancer)

Metastatic Castrate Resistant Prostate Cancer (mCRPC)

Researchers in this study want to compare how well drug radium-223 dichloride (Xofigo) and androgen receptor pathway inhibitor (ARPI) therapy work in participants with prostate gland cancer which has spread to the bone and progressed on or after one line of ARPI therapy. Meanwhile researchers want to compare the safety of radium-223 dichloride and ARPI therapy. Radium-223 dichloride is known as a radioactive drug that is taken up by bones after it is injected into the body. It works by giving off a type of radioactivity that travels a very short distance and kills the tumor cells that have spread to the bone without major effects to the healthy cells. It has been approved in many countries for the treatment of patients with prostate cancer which has spread to the bone. The ARPI drugs used in this study will be either abiraterone acetate (Zytiga) (plus prednisone/prednisolone) or enzalutamide (Xtandi). Both of them are standard approved medications which are used in the treatment of advanced prostate cancer. Participants in this study will receive either Radium-223 dichloride or a ARPI therapy. Radium-223 dichloride will be given as an infusion into one of the veins on Day 1 of each 4-week cycle for a total of up to 6 cycles. Oral ARPI therapy will be given per the standard approved dose once daily until the disease has progressed. Participants will visit the hospital or clinic every 2 weeks for the first 6 cycles, and only on the first day of each cycle from cycle 7 and onwards. Observation for each participant will last for about 2 years in total. Blood and urine samples will be collected from the participants and participants will be asked to complete questionnaires about the well-being and the pain.

Endometrial High Grade Endometrioid Adenocarcinoma Fallopian Tube Clear Cell Adenocarcinoma Fallopian Tube Endometrioid Adenocarcinoma Fallopian Tube High Grade Serous Adenocarcinoma +25

This phase I trial studies the side effects and best dose of peposertib when given together with pegylated liposomal doxorubicin hydrochloride in treating patients with high or low grade ovarian cancer that has come back after a period of improvement (recurrent). Peposertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as pegylated liposomal doxorubicin hydrochloride, 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 peposertib and pegylated liposomal doxorubicin hydrochloride may work better in treating patients with ovarian cancer compared to pegylated liposomal doxorubicin hydrochloride alone.

This phase III trial studies how well the combination of pembrolizumab, paclitaxel and carboplatin works compared with paclitaxel and carboplatin alone in treating patients with endometrial cancer that is stage III or IV, or has come back after a period of improvement (recurrent). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Paclitaxel and carboplatin are chemotherapy drugs used as part of the usual treatment approach for this type of cancer. This study aims to assess if adding immunotherapy to these drugs is better or worse than the usual approach for treatment of this cancer.

Efficacy and Safety of Pembrolizumab (MK-3475) in Combination With Bacillus Calmette-Guerin (BCG) in High-Risk Non-Muscle Invasive Bladder Cancer (HR NMIBC) (MK-3475-676/KEYNOTE-676)

High-risk Non-muscle Invasive Bladder Cancer

Researchers are looking for new ways to treat high-risk non muscle invasive bladder cancer (HR NMIBC). NMIBC is cancer in the tissue that lines the inside of the bladder but has not spread to the bladder muscle or outside of the bladder. High-risk means NMIBC may have a high chance of getting worse or coming back after treatment. The goals of this study are to learn: 1. If more people who receive pembrolizumab with Bacillus Calmette-Guerin (BCG) have no signs of cancer in their body and live longer without the cancer growing, spreading, or coming back compared to people who receive BCG alone. 2. About the safety and how well people tolerate BCG alone or in combination with pembrolizumab.

PEACE V: Salvage Treatment of OligoRecurrent Nodal Prostate Cancer Metastases

Prostate Cancer Prostate Cancer Metastatic Metastatic Cancer Oligometastatic Cancer

A proportion of prostate cancer (PCa) patients develop relapse following curative local treatment. Regional nodal recurrence is an emerging clinical situation since the introduction of new molecular imaging methods in the restaging of recurrent prostate cancer. More specifically, a subgroup of these patients is being diagnosed with a recurrence confined to the regional lymph nodes and limited in number (oligorecurrence) using choline or PSMA PET-CT. As there are no specific treatment recommendations for these type of patients, different treatment approaches are currently used, mostly focusing on local ablative treatments using radiotherapy or surgery. These treatments are coined metastasisdirected therapy (MDT). MDT in combination with or without temporary ADT could delay the subsequent risk of progression, and even cure limited regional nodal recurrences. Consequently, lifelong palliative ADT, with its toxicity and excess in non-cancer mortality might be postponed. The proposed trial randomizes patients with oligorecurrent nodal prostate cancer following primary PCa treatment to either metastasis-directed therapy (MDT) (salvage lymph node dissection, sLND or stereotactic body radiotherapy, SBRT) or MDT plus whole pelvis radiotherapy (WPRT: 45 Gy in 25 fractions).

Safety and Immune Response to a Mammaglobin-A DNA Vaccine In Breast Cancer Patients Undergoing Neoadjuvant Endocrine Therapy

Breast Cancer Breast Carcinoma Malignant Neoplasm of Breast

The purpose of this research study is to find out about the safety of injecting the gene (DNA) for mammaglobin-A into people with breast cancer. The DNA used in this study was purified from bacteria and contains the gene for mammaglobin-A. Mammaglobin-A is a protein that is highly expressed by breast cancer cells. Injection of mammaglobin-A DNA may be a way to generate an immune response to breast cancer cells. There is evidence that an immune response may be a way to fight cancer. In addition to evaluating the safety of the mammaglobin-A injection, this study is also looking at the immune response that the participant's body has after each injection.

Trial of Preoperative Therapy for Gastric and Esophagogastric Junction Adenocarcinoma

Gastric Cancer

Gastric cancer remains a significant global public health problem. Although in developed countries its incidence has dramatically decreased, on a worldwide scale it is still a leading cause of cancer-related deaths. Surgery is the only potentially curative treatment for gastric cancer. Although the survival rates for patients with early stage disease (stage 1A and 1B) are good, this subgroup of patients constitutes only 20% of those undergoing resection. The majority of patients will have locally advanced or metastatic disease at presentation, which has an extremely poor prognosis. The current five-year survival rate for gastric cancer in Western countries is approximately 20-30%, a figure that has improved little over the past 30 years. The intervention arm in TOPGEAR consists of pre-operative chemotherapy, pre-operative chemoradiotherapy, surgery and post-operative chemotherapy. The control arm consists of pre-operative chemotherapy, surgery and post-operative chemotherapy. The primary objective of TOPGEAR is to investigate whether the addition of chemoradiotherapy to chemotherapy is superior to chemotherapy alone in the neoadjuvant setting by improving pathological complete response rates in the first instance, and subsequently overall survival, in patients undergoing adequate surgery (D1+ dissection) for resectable gastric cancer.

Impact of Chewing Gum on Bowel Preparation in Patients Undergoing Colonoscopy

Colon Cancer Screening

Colorectal cancer is the second leading cause of cancer deaths that could be prevented in the United States. Colonoscopy is the best test for finding and removing polyps before they turn into cancer. However, many people are hesitant to have a colonoscopy because of the bowel preparation. The preparation can be difficult to tolerate, with patients often struggling to finish it due to the taste, volume, or side effects like nausea and bloating. This can lead to incomplete procedures or discourage people from getting screened at all. Chewing sugar-free gum is a simple, low-cost, and safe intervention that may make the preparation process easier. One study from China found that chewing gum did not change the quality of bowel cleansing, but patients reported that they were more satisfied with the process. No U.S.-based studies have tested this strategy, and no prior research has looked at whether gum chewing has different effects in people using high-volume versus low-volume prep solutions. The investigators will randomize 160 participants to the stated intervention or control using computer-generated 1:1 randomization. Upon completing the study, the investigators will analyze the data. By studying gum chewing during bowel preparation, the investigators hope to find out whether this small change can make bowel prep more tolerable and encourage more patients to complete their colonoscopy. If successful, this approach could help more people get screened, leading to earlier detection and prevention of colorectal cancer in the community.

Comparing Radiation Therapy to Usual Treatment for Patients With High-Risk Bone Metastases That Are Not Causing Pain, PREEMPT Trial

Metastatic Malignant Neoplasm in the Bone Metastatic Malignant Solid Neoplasm

This phase III trial compares the effect of adding radiation therapy to usual treatment on the occurrence of bone-related complications in cancer patients with high-risk bone metastases that are not causing symptoms, such as pain (asymptomatic). High-risk bone metastases are defined by their location (including hip, shoulder, long bones, and certain levels of the spine), or size (2 cm or larger). These bone metastases appear to be at higher risk of complications such as fracture, spinal cord compression, and/or pain warranting surgery or radiation treatment. Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. The total dose of radiation can be delivered in a single day or divided in smaller doses for up to 5 days of total treatment. Usual treatment for asymptomatic bone metastases may include drugs that prevent bone loss, in addition to the treatment for the primary cancer or observation (which means no treatment until symptoms appear). Evidence has shown that preventative radiation therapy may be effective in lowering the number of bone metastases-related complications, however, it is not known if this approach is superior to usual care. Adding radiation therapy to usual treatment may be more effective in preventing bone-related complications than usual care alone in cancer patients with asymptomatic high-risk bone metastases.
