The purpose of this study is to learn about the safety of a new pneumococcal vaccine and how the new pneumococcal vaccine helps to fight against germs in infants when compared to the pneumococcal vaccine that is currently in use, 20vPnC (Prevnar 20®). To ensure that the new vaccine (PG4) stays stable, it is placed in a liquid mixture of sterile water and other substances (a solution). This study will also test if there is a difference in the safety and immune effects of the new pneumococcal vaccine when it is one type of solution compared to when it is in a different type of solution. The immune response is how the body's cells, tissues and organs work together to protect the body from infection. Blood samples will be used to measure the amount of antibodies produced after the vaccination. Antibodies are proteins that protect you when an unwanted germ enters the body. This will help understand how well the new pneumococcal vaccine works. This vaccine can possibly provide protection against pneumococcal disease. Pneumococcal disease includes a variety of infections caused by a specific germ, Streptococcus pneumoniae. This study is seeking participants who are: - male or female infants who are 2 months of age, - infants born at 36 weeks (about 8 and a half months) of pregnancy or later; and, - said to be healthy by the study doctor There are three groups in this study. All participants will be assigned to one of the three groups. All study vaccines will be given as a single shot into the left thigh muscle. Participants in the three groups will have 3 blood samples collected during the 1 and a half years they are in the study. The first 400 people who enter the study will be assigned to either Group 1 or Group 2. Half the participants in Group 1 and half the participants in Group 2 will receive 4 doses at 2, 4, 6, and 12 to 15 months of age of PG4 mixed in the first solution. The other half of the participants in Groups 1 and 2 will receive 4 doses of 20vPnC (Prevnar 20®) at 2, 4, 6, and 12 to 15 months of age. The main difference between Groups 1 and 2 is that participants in Group 2 will have the first blood sample collected at an earlier time than those in Group 1. Once 400 people have been assigned to Groups 1 and 2 then 100 new participants will be assigned to Group 3. Half the participants in Group 3 will receive PG4 in the second solution at 2, 4, 6, and 12 to 15 months of age. The other half of the participants in Groups 3 will receive 4 doses of 20vPnC (Prevnar 20®) at 2, 4, 6, and 12 to 15 months of age. Participants will take part in this study for about 16 to 19 months (about 1 and a half years). During this time, participants will have 6 study clinic visits and 1 to 2 phone calls. At these study clinic visits, parent(s) or legal guardian(s) will be asked if the participant experienced any side effects. A side effect is an unintentional or unexpected reaction to a vaccine.

This phase II trial tests whether TRC102 (methoxyamine hydrochloride) in combination usual care treatment comprised of pemetrexed, cisplatin or carboplatin, and radiation therapy followed by durvalumab works better than the usual care treatment alone to shrink tumors in patients with stage III non-squamous non-small cell lung cancer (NSCLC). TRC102 is in a class of drugs called antineoplastic agents. It blocks the ability of a cell to repair damage to its DNA and may kill cancer cells. It may also help some anticancer drugs work better. Pemetrexed is in a class of medications called antifolate antineoplastic agents. It works by stopping cells from using folic acid to make DNA and may kill cancer cells. Chemotherapy drugs, such as cisplatin, 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. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Radiation therapy uses high energy sources to kill tumor cells and shrink tumors. Giving TRC102 in combination with usual care treatment may be more effective than usual care treatment alone in stabilizing and lengthening survival time in patients with stage III non-squamous NSCLC.

This trial studies how well a centralized care strategy works in improving the quality of smoking cessation and shared decision making among patients who smoke and are considering lung cancer screening. The centralized care strategy is a model where smokers eligible for lung cancer screening are referred to a dedicated tobacco treatment program where they receive both the shared decision-making and initiate smoking cessation counseling prior to their visit with a primary care provider. Utilizing the centralized care model may work better in helping people quit smoking and make informed decisions about lung cancer screening compared to usual care.

This phase II trial studies how well olaparib works in treating patients with bladder cancer and other genitourinary tumors with deoxyribonucleic acid (DNA)-repair defects that has spread to other places in the body (advanced or metastatic) and usually cannot be cured or controlled with treatment. PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing.

Objectives: This protocol addresses the first phase of a larger project funded by the Patient-Centered Outcomes Research Institute to help heavy smokers make informed decisions about lung cancer screening with low-dose computed tomography (CT). A separate IRB protocol will be submitted for the larger, comparative study. In this initial development phase, our prototype patient decision aid will be updated to reflect current guidelines about lung cancer screening. The updated aid will then be pilot-tested in a new sample of patients. In addition, several of the study measures will be refined and further developed in preparation for the larger study. The specific aims of the measures and decision aid development phase of this project are as follows: Update the aid to reflect current screening guidelines and refine the aid via cognitive testing with patients/smokers; and pilot test the updated aid for acceptability with patients/smokers. Modify our current measure of lung cancer knowledge, conduct cognitive testing of the new measure with patients/smokers, and evaluate the reliability of the new measure in a sample patients/smokers.

The study hypothesis is that BCG naïve non-muscle invasive bladder cancer (NMIBC) patients treated with intravesical Gemcitabine + Docetaxel (GEMDOCE) will result in a non-inferior event-free survival (EFS) compared to standard treatment with intravesical BCG. The purpose of this study is to test whether Gemcitabine + Docetaxel is a better or worse treatment than the usual BCG therapy approach. The primary objective of this study is to determine the event free survival (EFS) of BCG-naïve high grade non-muscle invasive bladder cancer patients treated with intravesical BCG vs Gemcitabine + Docetaxel. Secondary objectives are as follows: to compare changes in cancer-specific and bladder cancer-specific QOL from baseline to treatment between BCG-naïve high grade NMIBC patients receiving BCG and GEMDOCE, to determine the cystectomy free survival (CFS) of BCG-naïve high grade NMIBC patients treated with intravesical BCG vs GEMDOCE, to determine the progression free survival (PFS) of BCG-naïve high grade NMIBC patients treated with intravesical BCG vs GEMDOCE, and to determine the safety and toxicity of BCG-naïve high grade NMIBC patients treated with intravesical BCG vs GEMDOCE.

The use of imaging is increasing in clinical practice, either for diagnosis or intervention. In these imaging processes, contrast medium (CM) is widely used. However, CM administration can induce contrast-induced nephropathy (CI-AKI). CI-AKI is the third most common cause of renal insufficiency, and its incidence varies from 2% to 50% depending on patient risk factors; in addition, studies have shown that CI-AKI occurs in 2% to 25% of patients undergoing coronary intervention. CI-AKI is associated with significant mortality and morbidity in patients undergoing coronary angiography or other diagnostic contrast studies. We assessed the latest promising evidence on the ability of remote ischemic preconditioning (RIPC) to reduce the incidence of CI-AKI in patients undergoing Coronary Angiogram (CA) or diagnostic contrast studies such as CT angiogram, while at the same time being a non-invasive, low cost, easy, and safe method with absence of adverse effects. However, more randomized controlled trials are needed to confirm these preliminary results. The aim of this study is to minimize the incidence of CI-AKI at the University of Texas Medical Branch (UTMB). If found to be an effective method, RIPC would help minimize the incidence of CI-AKI in all institutions across the globe, who would adopt this intervention. The primary objective: i) reduce the rise in creatinine to < 0.5 mg/dL post-CA in moderate to high risk patients and ii) reduce the incidence of renal replacement therapy post-CA in moderate to high risk patients; iii) we also aim to establish that RIPC is safe and effective. We hypothesize that the use of RIPC, when added to standard medical therapy (pre-and post-CA hydration), will mitigate the effects of contrast on the renal vasculature and lessen the incidence of CI-AKI in moderate to high risk patients at the University of Texas Medical Branch. The use of iodinated contrast to visually enhance target vasculature is a widely used diagnostic technique that is performed daily at UTMB, and around the world, for the diagnosis and management of a variety of conditions. A common complication of this procedure is acute kidney injury (AKI), generally referred to as contrast-induced nephropathy (CI-AKI). This complication can range from an isolated rise in serum creatinine to severe renal dysfunction necessitating renal replacement therapy. The incidence of CI-AKI has been reported as approximately 2-50%, depending upon the definition and sensitivity of assay employed to assess GFR in the hospital setting. In addition, CI-AKI is associated with significant mortality and morbidity. If proven to be beneficial, RIPC will bring about a reduction in incidence of CI-AKI, and thus help to reduce hospitalization and mortality from renal etiology following a given contrast procedure.

The dose escalation phase of this trial identifies the safety, side effects and best dose of ceralasertib (AZD6738) when given in combination with trastuzumab deruxtecan (DS-8201a) in treating patients with solid tumors that have a change (mutation) in the HER2 gene or protein and have spread to other places in the body (advanced). The dose expansion phase (phase Ib) of this trial compares how colorectal and gastroesophageal cancers with HER2 mutation respond to treatment with a combination of ceralasertib and trastuzumab deruxtecan versus trastuzumab deruxtecan alone. Ceralasertib may stop the growth of tumor cells and may kill them by blocking some of the enzymes needed for cell growth. Trastuzumab deruxtecan is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called deruxtecan. Trastuzumab attaches to HER2 positive cancer cells in a targeted way and delivers deruxtecan to kill them. Ceralasertib and trastuzumab deruxtecan may be safe, tolerable and effective in treating patients with advanced solid tumors expressing the HER2 protein or gene.
