The AIRTIVITY® Study: A Study to Find Out Whether BI 1291583 Helps People With Bronchiectasis
Recruiting
This study is open to adults with bronchiectasis. People can participate in this study if they produce sputum and have had flare-ups (also called exacerbations). The purpose of this study is to find out whether a medicine called BI 1291583 helps people with bronchiectasis. Participants are put into 2 groups randomly, which means by chance. One group takes BI 1291583 tablets and the other group takes placebo tablets. A placebo tablet looks like the BI 1291583 tablet but does not contain any medi... Read More

Testing the Addition of MEDI4736 (Durvalumab) to Chemotherapy Before Surgery for Patients With High-Grade Upper Urinary Tract Cancer
Recruiting
This phase II/III trial compares the effect of adding durvalumab to chemotherapy versus chemotherapy alone before surgery in treating patients with upper urinary tract cancer. 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. Chemotherapy drugs, such as methotrexate, vinblastine, doxorubicin, cisplatin, and gemcitabine work in different ways to stop the growth of... Read More

ARD-101 for Treatment of PWS: The Hunger Elimination or Reduction Objective Trial
Recruiting
The goal of this clinical trial is to learn if ARD-101 works to treat hyperphagia-related behavior in patients with Prader-Willi syndrome (PWS). It will also teach us about the safety of ARD-101. The main questions it aims to answer are: * Does ARD-101 improve the total score of the HQCT-9 (hyperphagia questionnaire for clinical trials, 9 questions)? * What medical problems do participants have when taking ARD-101? Researchers will compare ARD-101 to a placebo (a look-alike substance that con... Read More

Testing Early Treatment for Patients With High-Risk Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Leukemia (SLL), EVOLVE CLL/SLL Study
Recruiting
This phase III trial compares early treatment with venetoclax and obinutuzumab versus delayed treatment with venetoclax and obinutuzumab in patients with newly diagnosed high-risk chronic lymphocytic leukemia or small lymphocytic lymphoma. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Immunotherapy with monoclonal antibodies, such as obinutuzumab, may help t... Read More

A Study of Disitamab Vedotin Alone or With Pembrolizumab in Urothelial Cancer That Expresses HER2
Recruiting
This study is being done to see if a drug called disitamab vedotin, alone or with pembrolizumab, works to treat HER2 expressing urothelial cancer. It will also test how safe the drug is for participants. Participants will have cancer that has spread in the body near where it started (locally advanced) and cannot be removed (unresectable) or has spread through the body (metastatic). It will also study what side effects happen when participants get the drug. A side effect is anything a drug does... Read More

A Plant-Based Whole-Foods Meal Delivery Service for Patients With Multiple Myeloma Undergoing Autologous Hematopoietic Cell Transplant
Recruiting
This clinical trial evaluates the impact of a plant-based whole-foods delivery service on the microbiome in patients with multiple myeloma undergoing an autologous hematopoietic cell transplant. An autologous hematopoietic cell transplant is a procedure in which blood-forming stem cells (cells from which all blood cells develop) are removed, stored, and later given back to the same person. Loss of microbial diversity within the intestinal tract has been associated with poor outcomes for patients... Read More

Venetoclax and HMA Treatment of Older and Unfit Adults With FLT3 Mutated Acute Myeloid Leukemia (AML) (A MyeloMATCH Treatment Trial)
Recruiting
This phase II MyeloMATCH treatment trial compares the usual treatment of azacitidine and venetoclax to the combination treatment of azacitidine, venetoclax and gilteritinib in treating older and unfit patients with acute myeloid leukemia and FLT3 mutations. Azacitidine is a drug that is absorbed into DNA and leads to the activation of cancer suppressor genes, which are genes that help control cell growth. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may... Read More
