Testing the Impact of an Anti-Cancer Drug, Atezolizumab, After Surgery to Prevent Early Stage Non-small Cell Lung Cancer From Returning, AASI-NSCLC Trial
This phase III trial compares the effect of atezolizumab (or atezolizumab and recombinant human hyaluronidase) to standard observation for preventing cancer return after surgery (recurrence) in patients who have undergone a complete surgical removal (resection) of stage I non-small cell lung cancer (NSCLC). Patients who have undergone resection for lung cancer are typically followed by observation or active surveillance, which involves closely watching a patient's condition but not giving treatment unless there are changes in test results. During active surveillance, patients are given certain exams and tests done on a regular schedule. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Atezolizumab and recombinant human hyaluronidase is a formulation of atezolizumab combined with an enzyme called hyaluronidase, which helps increase tissue absorption of the drug. Giving atezolizumab or atezolizumab and recombinant human hyaluronidase after resection may be effective for preventing NSCLC recurrence, and may be a better approach to treating patients with stage I NSCLC than the usual observation approach.

Nivolumab in Treating Patients With Localized Kidney Cancer Undergoing Nephrectomy
This phase III trial compares nephrectomy (surgery to remove a kidney or part of a kidney) with nivolumab to the usual approach of nephrectomy followed by standard post-operative follow-up and monitoring, in treating patients with kidney cancer that is limited to a certain part of the body (localized). Nivolumab is a drug that may help stimulate the immune system to attack any cancer cells that may remain after surgery. The addition of nivolumab to the usual surgery could prevent the cancer from returning. It is not yet known whether nivolumab and nephrectomy is more effective than nephrectomy alone in treating patients with kidney cancer.

Lenalidomide and Dinutuximab With or Without Isotretinoin in Treating Younger Patients With Refractory or Recurrent Neuroblastoma
This phase I trial studies the side effects and best dose of lenalidomide when given together with dinutuximab with or without isotretinoin in treating younger patients with neuroblastoma that does not respond to treatment or that has come back. Drugs used in chemotherapy, such as lenalidomide and isotretinoin, 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. Monoclonal antibodies, such as dinutuximab, may interfere with the ability of tumor cells to grow and spread. Giving more than one drug (combination chemotherapy) together with dinutuximab therapy may kill more tumor cells.

Development of 4D Flow MRI for Risk Stratification of Variceal Bleeding in Cirrhosis
The goal of this research is to validate novel non-invasive Magnetic resonance imaging (MRI) biomarkers to detect Gastroesophageal varices (GEV) in patients with cirrhosis, including fractional flow change in the portal vein and elevated azygos flow. End-stage liver disease (cirrhosis) is characterized by advanced fibrosis, liver failure, and portal hypertension. There are many causes of cirrhosis, including viral hepatitis, alcohol abuse, and perhaps most importantly, non-alcoholic fatty liver disease (NAFLD) and its aggressive subset, non-alcoholic steatohepatitis (NASH). 3 million new cases of end-stage liver disease (cirrhosis) are expected over the next decade. In cirrhosis, portosystemic collaterals that shunt blood away from the liver develop due to increased portal pressure. Gastroesophageal varices (GEV) are the most clinically relevant because they can cause fatal internal bleeding. GEV bleeding carries \~20% mortality at 6 weeks, and \~34% overall mortality. Identification of at-risk varices, prior to bleeding, is of paramount importance to initiate primary prophylaxis. To identify and treat at-risk patients, current guidelines recommend regular esophagogastroduodenoscopy (EGD) and variceal band ligation. Detection of high-risk GEV is key to initiating primary prophylaxis, which can reduce mortality by 50-70%. However, endoscopy is invasive and often unnecessary when no treatment is required. Therefore, the American Association for the Study of Liver Diseases has identified the development of "non-invasive markers that predict the presence of high-risk varices" as a major unmet need.

Obinutuzumab With or Without Umbralisib, Lenalidomide, or Combination Chemotherapy in Treating Patients With Relapsed or Refractory Grade I-IIIa Follicular Lymphoma
This phase II trial studies how well obinutuzumab with or without umbralisib, lenalidomide, or combination chemotherapy work in treating patients with grade I-IIIa follicular lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Immunotherapy with obinutuzumab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Umbralisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Biological therapies, such as lenalidomide, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Chemotherapy drugs, such as cyclophosphamide, doxorubicin, vincristine, prednisone, and bendamustine, 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. It is not yet known whether giving obinutuzumab with or without umbralisib, lenalidomide, or combination chemotherapy will work better in treating patients with grade I-IIIa follicular lymphoma.

Intacs Prescription Inserts for Keratoconus Patients
The US food and Drug Administration (FDA) originally approved INTACS prescription inserts in April 1999 for the correction of low levels of nearsightedness (-1.00 to -3.00 diopters). Additional clinical data have shown that INTACS are safe for the treatment of keratoconus, in July 2004, FDA approved INTACS inserts for the treatment of keratoconus as a Humanitarian Use Device (FDA approval letter attached). The statute and the implementing regulation of FDA (21 CFR 814.124 (aj) require IRB review and approval before a HUD is used.INTACS prescription inserts are composed of two clear segments, each having an arc length of 150°, they are manufactured form a biomedical material called polymethylmethacrylate (PMMA) and are available in three thicknesses. Two INTACS inserts ranging from 0.250mm to 0.350mm may be implanted depending on the orientation of the cone and the amount of myopia and astigmatism to be reduced.

Testing the Safety and Feasibility of Immunotherapy Drugs, Botensilimab and Balstilimab, Before Surgery for Clear Cell Renal Cell Carcinoma, NEO RoBOT Trial
This phase II trial tests the effect of botensilimab and balstilimab before surgery (neoadjuvant) in treating patients with high-risk clear cell renal cell cancer that has not spread from where it first started to other areas of the body (non-metastatic). The current standard treatment for patients with non-metastatic clear cell renal cell cancer may include surgery to completely remove the tumor. This typically involves removing the kidney or part of the kidney (nephrectomy). Immunotherapy with monoclonal antibodies, such as botensilimab and balstilimab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Giving neoadjuvant botensilimab and balstilimab may be safe, tolerable, and/or effective in treating patients with high-risk non-metastatic clear cell renal cell cancer before undergoing a nephrectomy.

Testing the Addition of an Anti-cancer Drug, Copanlisib, to the Usual Immunotherapy (Nivolumab With or Without Ipilimumab) in Patients With Advanced Solid Cancers That Have Changes in the Following Genes: PIK3CA and PTEN
This phase I/II trial studies the side effects and best dose of copanlisib when given together with nivolumab and ipilimumab and to see how well they work in treating patients with solid cancers that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and have changes in PIK3CA and PTEN genes. Copanlisib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. The addition of copanlisib to usual immunotherapy may work better in treating patients with solid cancers compared to usual immunotherapy alone.

Testing Docetaxel-Cetuximab or the Addition of an Immunotherapy Drug, Atezolizumab, to the Usual Chemotherapy and Radiation Therapy in High-Risk Head and Neck Cancer
This phase II/III trial studies how well radiation therapy works when given together with cisplatin, docetaxel, cetuximab, and/or atezolizumab after surgery in treating patients with high-risk stage III-IV head and neck cancer the begins in the thin, flat cells (squamous cell). Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as cisplatin and docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Cetuximab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. The purpose of this study is to compare the usual treatment (radiation therapy with cisplatin chemotherapy) to using radiation therapy with docetaxel and cetuximab chemotherapy, and using the usual treatment plus an immunotherapy drug, atezolizumab.

Nivolumab in Combination With Chemo-Immunotherapy for the Treatment of Newly Diagnosed Primary Mediastinal 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.

Does Capsuloplasty Reduce External Rotation After Coracoid Impingement?
The coracoid anchor (Latarjet procedure) is the gold standard technique for treating recurrent anterior shoulder instability. Despite excellent postoperative stability, a reduction in external rotation has been reported, which can affect function, glenohumeral kinematics, and return to sports, particularly among athletes in combat and contact sports. The combination of an anterior capsuloplasty with the coracoid buttress is performed inconsistently among surgeons, with no consensus; the capsular repair techniques associated with the Latarjet procedure vary widely among teams. Some teams routinely perform capsular repair to enhance stability and reposition the capsule on the glenoid rim, while others consider it non-essential and potentially responsible for further limiting external rotation. To date, there are few studies specifically evaluating the impact of capsuloplasty on joint range of motion beyond the end-stop, and the available results remain contradictory. In 2023, the team of Kim et al. suggested that the Latarjet technique without capsular repair resulted in good restoration of laxity and good clinical outcomes, with less early postoperative limitation of external rotation than that observed with the same technique combined with capsular repair. Nevertheless, at 1 year, there was no significant deficit in external rotation between the two groups. A prospective randomized comparative analysis will determine whether the addition of capsuloplasty significantly alters ranges of motion, given identical surgical and rehabilitation protocols. The results could clarify the indications for this procedure, optimize surgical practices, and improve recommendations for the management of shoulder instability.

Combination Chemotherapy With or Without Ganitumab in Treating Patients With Newly Diagnosed Metastatic Ewing Sarcoma
This randomized phase III trial studies how well combination chemotherapy with or without ganitumab works in treating patients with newly diagnosed Ewing sarcoma that has spread to other parts of the body. Treatment with drugs that block the IGF-1R pathway, such as ganitumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as vincristine, doxorubicin, cyclophosphamide, ifosfamide, and etoposide, 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. It is not yet known whether adding ganitumab to combination chemotherapy is more effective in treating patients with newly diagnosed metastatic Ewing sarcoma.

Feasibility Study to Evaluate the Role of a Novel Device in Childbirth
Accidentally retained surgical items or swabs are well-recognised errors that result in adverse consequences for patients. This error is one of the commonest "Never Events" - patient safety incidents that are considered preventable. Although uncommon, these incidents can have devastating consequences. Retained surgical items have 70% re-interventions, reaching 80% morbidity and 35% mortality. Swabs or sponges are like small towels that soak up blood and body fluids so that the surgeon can visualise the operating area effectively. Swabs are used in all areas of surgery which include operations on the tummy, chest, limbs. They are also used in the vagina during childbirth, to assess for tears and to minimise blood oozing from the vagina. The common risk factors for this error are out of hours surgical or childbirth procedures, multiple handovers in the care of the patient, raised BMI (Body Mass Index) and unplanned change to the operative intervention. As the name suggests, a 'never event' should never happen in the first place. Never. Unfortunately, this is not the case. Incidents involving surgical swabs being left behind, particularly during a caesarean section or a perineal repair following a vaginal birth, are still happening despite over 100 years of institutional awareness of the problem and tentative solutions being implemented in clinical practice. never-event incidents involving retained surgical swabs are a widespread problem affecting healthcare systems worldwide. It is therefore reasonable to ask the question: why are surgical swabs being left behind and what can be done to prevent this from happening?

The SENTRY Study: Testing Whether Changes in Platelet RNA Enhance the Early Diagnosis of Ovarian Cancer
The purpose of the SENTRY (Stability Enhanced Transcriptional Analytics) Study is to test whether combining a unique analytical approach with changes in platelet RNA expression accurately diagnoses ovarian cancer. Using retrospective data, the investigators have developed an approach that appears to accurately classify ovarian cancer with relatively high sensitivity and specificity. The SENTRY Study will build upon these retrospective analyses to prospectively recruit women with ovarian cancer or an ovarian mass (and healthy control women), obtain platelet RNA samples from whole blood, and perform validation analyses to test our hypothesis.

Treatment With Amivantamab and Hyaluronidase or Cetuximab for Advanced Skin Cancer in People With a Weakened Immune System
This phase II trial compares the effect of amivantamab and hyaluronidase to cetuximab for the treatment of skin (cutaneous) squamous cell carcinoma that has come back after a period of improvement and has not spread to other parts of the body (locally recurrent) or that has spread from where it first started (primary site) to other places in the body (metastatic). Amivantamab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Hyaluronidase is an endoglycosidase. It helps to keep amivantamab in the body longer, so that the medications will have a greater effect. Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of cancer cells. This may help keep cancer cells from growing. Giving amivantamab and hyaluronidase may be as effective as cetuximab for the treatment of locally recurrent or metastatic cutaneous squamous cell carcinoma.
