The purpose of this study is to evaluate the efficacy and safety of belzutifan monotherapy and belzutifan plus palbociclib combination therapy in participants with advanced clear-cell renal cell carcinoma (ccRCC) who experienced disease progression on or after receiving prior therapy. Part 1 will establish the safety of belzutifan plus palbociclib and determine a recommended dosage of palbociclib for the combination therapy by ascending dose escalation. Part 2 will evaluate the efficacy and safety of belzutifan plus palbociclib at the dosage level determined in Part 1. Read Less

This phase II trial compares the effect of atezolizumab in combination with usual treatment with cabozantinib to cabozantinib alone in patients with papillary renal cell carcinoma that has spread to other places in the body (metastatic). Papillary renal cell carcinoma (PRCC) is a type of kidney cancer that forms in the lining of the tiny tubes in the kidney that return filtered substances that the body needs back to the blood and remove extra fluid and waste as urine. Most papillary tumors look like long, thin finger-like growths under a microscope. It is also called papillary kidney cancer or PRCC. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. Cabozantinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply and may also prevent the growth of new blood vessels that tumors need to grow. By these actions it may help slow or stop the spread of cancer cells. Combination therapy with atezolizumab and cabozantinib may shrink the cancer and allow a longer survival time in patients with metastatic renal cell carcinoma. Read Less

This phase I/II trial studies how well tiragolumab and atezolizumab works when given to children and adults with SMARCB1 or SMARCA4 deficient tumors that have either come back (relapsed) or do not respond to therapy (refractory). SMARCB1 or SMARCA4 deficiency means that tumor cells are missing the SMARCB1 and SMARCA4 genes, seen with some aggressive cancers that are typically hard to treat. Immunotherapy with monoclonal antibodies, such as tiragolumab and atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

This phase III trial tests whether adding trastuzumab and hyaluronidase-oysk (Herceptin Hylecta \[TM\]) or pertuzumab, trastuzumab and hyaluronidase-zzxf (Phesgo \[TM\]) to the usual chemotherapy (paclitaxel and carboplatin) works to shrink tumors in patients with HER2 positive endometrial cancer. Trastuzumab and pertuzumab are monoclonal antibodies and forms of targeted therapy that attach to specific molecules (receptors) on the surface of tumor cells, known as HER2 receptors. When trastuzumab or pertuzumab attach to HER2 receptors, 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. Hyaluronidase is an endoglycosidase. It helps to keep pertuzumab and trastuzumab in the body longer, so that these medications will have a greater effect. Hyaluronidase also allows trastuzumab and trastuzumab/pertuzumab to be given by injection under the skin and shortens their administration time compared to trastuzumab or pertuzumab alone. Paclitaxel is a taxane and in a class of medications called antimicrotubule agents. It stops tumor cells from growing and dividing and may kill them. 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 tumor cells. Giving Herceptin Hylecta or Phesgo in combination with paclitaxel and carboplatin may shrink the tumor and prevent the cancer from coming back in patients with HER2 positive endometrial cancer.

The purpose of this single-arm interventional study is to evaluate the long-term safety, efficacy, and durability of the Symplicity Spyral system in subjects treated with renal denervation. Additionally, long-term follow-up data will also be collected from eligible subjects previously treated in the SPYRAL PIVOTAL-SPYRAL HTN-OFF MED and SPYRAL HTN-ON MED studies. Read Less

This phase II/III compares the standard therapy (chemotherapy plus cetuximab) versus adding bevacizumab to standard chemotherapy, versus combination of just bevacizumab and atezolizumab in treating patients with head and neck cancer that has spread to other places in the body (metastatic or advanced stage) or has come back after prior treatment (recurrent). 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. 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. 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. Cisplatin and carboplatin are in a class of chemotherapy medications known as platinum-containing compounds. They work by killing, stopping, or slowing the growth of cancer cells. Docetaxel is in a class of chemotherapy medications called taxanes. It stops cancer cells from growing and dividing and may kill them. The addition of bevacizumab to standard chemotherapy or combination therapy with bevacizumab and atezolizumab may be better than standard chemotherapy plus cetuximab in treating patients with recurrent/metastatic head and neck cancers.

Living donor (LD) kidney transplantation is the optimal treatment for patients with end-stage kidney disease (ESKD). However, LDs take on a higher risk of future ESKD themselves. African American (AA) LDs have an even greater, 3.3-fold, risk of ESKD than white LDs post-donation. Because evidence suggests that Apolipoprotein L1 (APOL1) risk variants contribute to this greater risk, transplant nephrologists are increasingly using APOL1 testing to evaluate LD candidates of African ancestry. However, nephrologists do not consistently perform genetic counseling with LD candidates about APOL1 due to a lack of knowledge and skill in counseling about APOL1. Without proper counseling, APOL1 testing will magnify LD candidates' decisional conflict about donating, jeopardizing their informed consent. Given their elevated risk of ESRD post-donation, and AAs' widely-held cultural concerns about genetic testing, it is ethically critical to protect AA LD candidates' safety through APOL1 testing in a culturally competent manner to improve informed decisions about donating. No transplant programs have integrated APOL1 testing into LD evaluation in a culturally competent manner. Clinical "chatbots," mobile apps that use artificial intelligence to provide genetic information to patients and relieve constraints on clinicians' time, can improve informed treatment decisions and reduce decisional conflict. The chatbot "Gia," created by a medical genetics company, can be adapted to any condition. However, no chatbot on APOL1 is currently available. No counseling training programs are available for nephrologists to counsel AA LDs about APOL1 and donation in a culturally competent manner. Given the shortage of genetic counselors, increasing nephrologists' genetic literacy is critical to integrating genetic testing into practice. The objective of this study is to culturally adapt and evaluate the effectiveness of an APOL1 testing program for AA LDs at two transplant centers serving large AA LD populations (Chicago, IL, and Washington, DC). The APOL1 testing program will evaluate the effect of the culturally competent testing, chatbot, and counseling on AA LD candidates' decisional conflict about donating, preparedness for decision-making, willingness to donate, and satisfaction with informed consent. The specific aims are to: 1. Adapt Gia and transplant counseling to APOL1 for use in routine clinical practice 2. Evaluate the effectiveness of this intervention on decisional conflict, preparedness, and willingness to donate in a pre-post design 3. Evaluate the implementation of this intervention into clinical practice by using the RE-AIM framework to longitudinally evaluate nephrologist counseling practices and LDs' satisfaction with informed consent. The impact of this study will be the creation of a model for APOL1 testing of AA LDs, which can then be implemented nationally via implementation science approaches. APOL1 will serve as a model for integrating culturally competent genetic testing into transplant and other practices to improve patient informed consent. Read Less

Phase IV multi-center, US-centric, open-label, safety study enrolling participants with Hemophilia A or B with inhibitors, 12 years of age and older, who are either on long term prophylactic treatment (e.g., emicizumab) at risk of experiencing a breakthrough bleeding event (BE), or who are not on prophylactic treatment who may need to control a BE.

This phase III trial investigates the best dose of vinblastine in combination with selumetinib and the benefit of adding vinblastine to selumetinib compared to selumetinib alone in treating children and young adults with low-grade glioma (a common type of brain cancer) that has come back after prior treatment (recurrent) or does not respond to therapy (progressive). Selumetinib is a drug that works by blocking a protein that lets tumor cells grow without stopping. Vinblastine blocks cell growth by stopping cell division and may kill cancer cells. Giving selumetinib in combination with vinblastine may work better than selumetinib alone in treating recurrent or progressive low-grade glioma. Read Less

In parallel with the growth of American Thrombosis and Hemostasis Network's (ATHN) clinical studies, the number of new therapies for all congenital and acquired hematologic conditions, not just those for bleeding and clotting disorders, is increasing significantly. Some of the recently FDA-approved therapies for congenital and acquired hematologic conditions have yet to demonstrate long-term safety and effectiveness beyond the pivotal trials that led to their approval. In addition, results from well-controlled, pivotal studies often cannot be replicated once a therapy has been approved for general use.(1,2,3,4) In 2019 alone, the United States Food and Drug Administration (FDA) has issued approvals for twenty-four new therapies for congenital and acquired hematologic conditions.(5) In addition, almost 10,000 new studies for hematologic diseases are currently registered on www.clinicaltrials.gov.(6) With this increase in potential new therapies on the horizon, it is imperative that clinicians and clinical researchers in the field of non-neoplastic hematology have a uniform, secure, unbiased, and enduring method to collect long-term safety and efficacy data. ATHN Transcends is a cohort study to determine the safety, effectiveness, and practice of therapies used in the treatment of participants with congenital or acquired non-neoplastic blood disorders and connective tissue disorders with bleeding tendency. The study consists of 7 cohorts with additional study "arms" and "modules" branching off from the cohorts. The overarching objective of this longitudinal, observational study is to characterize the safety, effectiveness and practice of treatments for all people with congenital and acquired hematologic disorders in the US. As emphasized in a recently published review, accurate, uniform and quality national data collection is critical in clinical research, particularly for longitudinal cohort studies covering a lifetime of biologic risk.(7) Read Less

This phase III ALCHEMIST trial tests the addition of pembrolizumab to usual chemotherapy for the treatment of stage IIA, IIB, IIIA or IIIB non-small cell lung cancer that has been removed by surgery. 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. Chemotherapy drugs, such as cisplatin, pemetrexed, carboplatin, gemcitabine hydrochloride, and paclitaxel, 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 pembrolizumab with usual chemotherapy may help increase survival times in patients with stage IIA, IIB, IIIA or IIIB non-small cell lung cancer. Read Less
