The goal of this clinical trial is to learn if the Fenestrated TREO Stent-Graft System works to treat abdominal aneurysms in adults. An abdominal aneurysm is a bulge in the main blood vessel (the aorta) which carries blood from the heart, through the chest and abdomen. It will also learn about the safety of Fenestrated TREO Stent-Graft System. The main question it aims to answer is: Can the the Fenestrated TREO Stent-Graft System be used to treat participants with a specific type of abdominal aneurysm called a juxtarenal abdominal aortic aneurysm? Participants will: Have the the Fenestrated TREO Stent-Graft System implanted via an endovascular surgical procedure and visit the hospital for a follow up period of 5 years, for checkups, tests and imaging scans.

There is evidence to suggest that lidocaine can help reduce the pain associated with intramuscular injections of benzathine penicillin G (BPG) or Bicillin, used to treat syphilis infections. A study published in the Journal of Family Practice in 2001 compared the pain experienced during bicillin injections with and without the use of lidocaine. The study found that patients who received lidocaine injections before receiving bicillin reported significantly less pain compared to those who received bicillin injections without lidocaine. Per the International Union against Sexually Transmitted Infections (IUSTI) European Guidelines for syphilis management, lidocaine has been used as a diluent for BPG since 1998. In the United States (US), BPG often comes prepackaged and lidocaine is unable to be used as a diluent with the same ease as it is in Europe. In light of this, the investigators propose a randomized controlled trial of benzathine penicillin G with and without lidocaine to quantify any site pain reduction with lidocaine in patients being treated for syphilis. This study is a randomized, double blinded, placebo controlled trial. During this study, patients needing BPG treatment for syphilis will be screened for any penicillin allergies and consented to their participation. Each participant will receive 2 injections of BPG, 1.2 million units each (2x1.2 million units = 2.4 million units, the standard dose for syphilis treatment), as intramuscular injections, one in each gluteal muscle, with one of the injections randomly having 0.5ml of 1% lidocaine added while the other has 0.5 ml normal saline solution. The side of each injection will be randomized by the medical assistant (MA)/nurse filling the vials and the injecting MA will be blinded, as well as the study participant, as to which vial contains lidocaine and which contains normal saline. The participants will then be asked to rate their pain from 0-10 on each site of injection at 10 minutes post injection, then again at 24 hours after injection via email electronic survey (via RedCap). The differences in pain from the two injections will be compared and analyzed to see if lidocaine reduces pain associated with BPG injections compared to the control of normal saline added to BPG.

Patients with deletion of chromosome 9 P are rare (~200 in the medical literature) and have a diverse set of phenotypic characteristics. We propose using state of the art genome sequencing methods to define the location and size of the deleted portion of chromosome 9 P as well as the genetic background in affected patients (whole genome sequencing) and correlate the genes in the deleted portion of chromosome 9 P with specific phenotypic characteristics of each patient. Enrolled participants will be asked to complete a detailed questionnaire, complete a medical release form, and provide a biospecimen sample.

It is believed that targeted SERCA2a enzyme replacement in HFrEF patients will correct defective intracellular Ca2+ hemostasis, resulting in improved cardiac contractile function and energetics which will, in turn, translate to improved clinical outcomes. Additionally, it is hypothesized that correcting SERCA2a dysfunction will also improve coronary blood flow through correction of the impaired endothelium-dependent nitric oxide-mediated vasodilatation observed in heart failure.

Researchers are looking for new ways to treat extensive-stage small cell lung cancer (ES-SCLC). ES-SCLC is a type of lung cancer that has spread throughout the lung, to the other lung, or to other parts of the body. A standard (usual) treatment for ES-SCLC uses both chemotherapy and immunotherapy. - Chemotherapy is a treatment that works to destroy cancer cells or stop them from growing. - Immunotherapy is a treatment that helps the immune system fight cancer. Gocatamig and I-DXd (short for ifinatamab deruxtecan) are study medicines. Researchers want to know if giving gocatamig and I-DXd together can treat ES-SCLC. Researchers will also look at giving the study medicines with standard treatment. Gocatamig is a T-cell engager therapy. I-DXd is an antibody drug conjugate. - T-cell engager therapy is a certain type of immunotherapy that uses T-cells to find and destroy cancer cells. - A T-cell is a type of white blood cell, which are cells that help the body fight infection. - An antibody drug conjugate (ADC) is a treatment that attaches to a protein on cancer cells and delivers treatment to destroy those cells. The goals of this study are to learn: - About the safety of combining gocatamig and I-DXd and if people tolerate them together - If people who receive gocatamig and I-DXd have ES-SCLC respond, which means the cancer gets smaller or goes away

Researchers are looking for new ways to treat types of breast cancer that are both: - High-risk, which means the cancer may have a higher chance of getting worse or coming back after treatment - Early-stage, which means the cancer is in the breast or the lymph nodes around the breast The 2 types of breast cancer in this study are triple-negative breast cancer (TNBC) and hormone receptor (HR)-low positive/human epidermal growth factor receptor-2 (HER2) negative breast cancer. These cancers have zero or a low amount of a protein called HER2 and other proteins that attach to the hormones estrogen or progesterone. Sacituzumab tirumotecan (also known as sac-TMT or MK-2870), the study medicine, is a type of targeted therapy. A targeted therapy is a treatment that works to control how specific types of cancer cells grow and spread. The main goals of this study are to learn if people who receive sac-TMT, pembrolizumab, and chemotherapy: - Have fewer cancer cells found in the tumors and lymph nodes removed during surgery compared to those who receive only pembrolizumab and chemotherapy - Live longer without the cancer growing, spreading, or coming back compared to people who receive only pembrolizumab with chemotherapy

This phase III trial compares 6 months of human epidermal growth factor receptor 2 (HER2)-targeted therapy to 12 months of HER2-targeted therapy for the treatment of HER2-positive (+) breast cancer in patients that had a pathologic complete response (pCR) after preoperative (neoadjuvant) chemotherapy with trastuzumab. Trastuzumab and pertuzumab are monoclonal antibodies and forms of targeted therapy that attach to a receptor protein called HER2. HER2 is found on some cancer cells. When trastuzumab or pertuzumab attach to HER2, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Giving 6 months of HER2-targeted therapy may work better than giving 12 months for the treatment of HER2+ breast cancer in patients that had a pCR after neoadjuvant chemotherapy with trastuzumab.

This is a four-part study evaluating the safety and efficacy of a PSMA-directed radioantibody (rosopatamab tetraxetan, conjugated to either In-111 or Ac-225). Part 1 will consist of one administration of In-111-rosopatamab tetraxetan to characterize the biodistribution of the radioantibody to target organs and prostate cancer lesions. Participants then will be enrolled into either Part 2 (Dose Optimization) or Part 3 (Dose Escalation and Expansion) depending on their prior treatment history. Part 4 will be an extended regimen in dose escalation and expansion. Participants qualifying for Part 2 will be randomized to receive Ac-225 rosopatamab tetraxetan in a single fractionated cycle (dose administration on Day 1 and Day 15) at either 45 or 60 kBq/Kg. Participants qualifying for Part 3 must have received prior Lu-177-PSMA-radioligand therapy and will receive Ac-225 rosopatamab tetraxetan in a single fractionated cycle at 45, 55, or 60 kBq/Kg. Dose limiting toxicities (DLTs) will be monitored in Part 3 to determine the recommended phase 2 dose (RP2D), and the study may enroll additional participants to be treated with the RP2D dose level. Participants qualifying for Part 4 will initially receive two doses (dose administration on Day 1 and Day 15) at the dose level selected in Part 2, followed by a single third dose of Ac-225 rosopatamab tetraxetan administered approximately 12 weeks after completion of the Part 2 fractionated dosing regimen. The starting dose level for Part 4 will be 22 kBq/kg (or fixed activity equivalent). Dose limiting toxicities (DLTs) will be monitored following administration of the third dose in Part 4 to determine the recommended phase 2 dose (RP2D) of a third dose of Ac-225 rosopatamab tetraxetan. Participants enrolled into any part will attend study visits which will include blood samples, electrocardiogram (ECG), radiographic imaging, and physical examinations along with other assessments.

This phase III trial compares the effect of giving triptorelin vs no triptorelin in preventing ovarian damage in adolescents and young adults (AYAs) with cancer receiving chemotherapy with an alkylating agents. Alkylating agents are part of standard chemotherapy, but may cause damage to the ovaries. If the ovaries are not working well or completely shut down, then it will be difficult or impossible to get pregnant in the future. Triptorelin works by blocking certain hormones and causing the ovaries to slow down or pause normal activity. The triptorelin used in this study stays active in the body for 24 weeks or about 6 months after a dose is given. After triptorelin is cleared from the body, the ovaries resume normal activities. Adding triptorelin before the start of chemotherapy treatment may reduce the chances of damage to the ovaries.

With modern therapy, the survival rate for pediatric brain tumor patients has significantly improved, with over 70% of patients surviving their disease. However, this progress often comes at the cost of substantial morbidity, with cognitive deficits being the primary obstacle to independent living. Robust predictors of cognitive decline and a comprehensive understanding of the underlying mechanisms of cognitive injury remain elusive. This study will prospectively investigate alterations in brain resting state networks following radiation therapy using functional imaging. The hypothesis is that radiation therapy leads to dose-dependent alterations in functional connectivity in the networks associated with higher level cognition, ultimately leading to cognitive decline.

Aim 1. To determine the factors contributing to pain in patients with chronic pelvic pain with and without endometriosis Aim 2. To determine the changes following endometriosis lesion removal surgery in pain and sex hormone levels. Aim 3. To identify factors predicting clinical pain reduction after lesion removal surgery. Additional exploratory aims might compare subgroups of patients such as patients with vs. without endometriosis, with vs. without additional chronic pain syndromes, and with vs. without hormonal treatment. In addition, the role of lesion-specific immune signatures and psychological factors on pain will be explored. Patients with pelvic pain potentially due to endometriosis will complete questionnaires including social, health, behavioral, and psychological questionnaires. Patients will also complete a 2.5 hours study visit of psychophysical assessments of thermal and pressure stimuli. In addition, blood, urine, and saliva samples will be collected for hormonal, immune, and genetic analyses. Additional samples might be collected and stored for future analyses. For some participants, these procedures will be completed several times, including before the surgery as well as 3 months, 6 months and 1 year after surgery. After the surgery, surveys assessing pain and other symptoms will be sent every week on the first month and then monthly for 1 year. In addition, during the surgery, biopsies will be collected and analyzed to determine hormonal, immune and genetic factors. For adolescents, a parent/legal guardian will be asked to assist in completing some of the health-related surveys (i.e., physical developmental survey, health survey, migraine history survey).

This phase II trial studies the good and bad effects of the combination of drugs called cabozantinib and nivolumab in treating patients with melanoma or squamous cell head and neck cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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. This trial may help doctors determine how quickly patients can be divided into groups based on biomarkers in their tumors. A biomarker is a biological molecule found in the blood, other body fluids, or in tissues that is a sign of a normal or abnormal process or a sign of a condition or disease. A biomarker may be used to see how well the body responds to a treatment for a disease or condition. The two biomarkers that this trial is studying are "tumor mutational burden" and "tumor inflammation signature." Another purpose of this trial is to help doctors learn if cabozantinib and nivolumab shrink or stabilize the cancer, and whether patients respond differently to the combination depending on the status of the biomarkers.
