This is a phase 1 study, randomized, double-blind, placebo-controlled, 2 treatment, 2 period crossover study to evaluate the pharmacokinetics, safety, and tolerability of a single inhaled dose of ASY202 in adults with stable asthma. Following screening, eligible participants will be enrolled and randomized to one of two treatment sequences. Participants will receive a single inhaled dose of ASY202 and a single inhaled dose of placebo, each administered once during separate study periods. During each treatment period, subjects will stay in the clinical research unit for safety monitoring and PK assessments, including serial blood sampling, spirometry, vital signs, clinical laboratory tests, and ECGs. Each period will include post dose assessments for up to 24 hours. Participants will return for their next treatment period after a washout interval to ensure complete clearance of study medication. All subjects will receive both treatments over the course of the study. A follow-up visit will occur after the last dose to assess ongoing safety and tolerability.

This study is testing an investigational inhaled migraine medication to see how well it works, how safe it is, and how well people tolerate it. Adults with migraine will receive both the study medication (ASY202) and a placebo (inactive treatment) at different times during the study. Neither participants nor study staff will know which treatment is given at the time. The medication is taken using a handheld dry powder inhaler to treat migraine attacks when they occur. Following screening, eligible participants will be enrolled and randomized to one of two treatments sequences i.e. one treatment sequence will receive ASY202 in treatment period 1 followed by placebo in treatment period 2 and other treatment sequence will receive placebo in treatment period 1 followed by ASY202 in treatment period 2. The study lasts about 16 weeks and includes a screening period, two treatment periods (with a minimum of 7 days washout period between the treatment periods), and a safety follow-up visit.

This phase III trial compares the effect of adding sonrotoclax to zanubrutinib versus zanubrutinib alone for the treatment of patients with untreated chronic lymphoblastic leukemia (CLL)/small lymphocytic lymphoma (SLL). Sonrotoclax 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. Zanubrutinib is in a class of medications called kinase inhibitors. It blocks a protein called BTK, which is present on B-cell (a type of white blood cells) cancers such as mantel cell lymphoma at abnormal levels. This may help keep cancer cells from growing and spreading. Giving sonrotoclax and zanubrutinib may be more effective than zanubrutinib alone for the treatment of untreated CLL/SLL.

This clinical trial compares patient (proband)-mediated communication to provider-mediated communication for improving genetic testing in first-degree relatives of patients with newly diagnosed colorectal cancer. It is estimated that 30% of cases of colorectal cancer have a genetic basis and about 15% of these patients have a disease-causing (pathogenic) inherited (germline) variant in a cancer susceptibility gene. Most individuals carrying a pathogenic germline variant are unaware of their cancer risk and may not meet guidelines for genetic testing. Identifying pathogenic germline variants or hereditary cancer syndromes in cancer patients has important implications for their at-risk relatives who may not know that they are at high risk for cancer. The burden of communicating this risk to first-degree relatives often falls on the patients, who may lack sufficient knowledge to correctly share and explain their genetic test results. Receiving provider-mediated communication of genetic testing results may be more effective at communicating genetic risk to first-degree relatives than the usual practice of proband-mediated communication.

This phase III trial compares the use of a digital chatbot enabled intervention to standard remote genetic services for increasing uptake of genetic counseling and testing among adolescents and young adult (AYA) cancer patients. Genetic testing for cancer predisposition syndromes has become standard evidence-based practice and can inform enhanced screening and risk reducing measures to reduce cancer morbidity and mortality. Despite this, many AYAs are not receiving recommended genetic counseling and testing. Offering remote telehealth services can address access barriers and chatbots and texting interventions could enhance patient outcomes and reduce provider and staff time. The use of a digital chatbot enabled intervention may be equally as effective as standard remote genetic services in AYA cancer patients undergoing genetic testing.

This phase III trial compares the effect of adding tivozanib to standard therapy pembrolizumab versus pembrolizumab alone for the treatment of patients with high-risk renal cell carcinoma (RCC). 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. Tivozanib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals tumor cells to multiply. This helps stop the spread of tumor cells. Giving pembrolizumab and tivozanib together may work better than pembrolizumab alone in treating patients with RCC.

This phase III trial tests whether continuous or intermittent zanubrutinib after achieving a complete remission (CR) with rituximab works in older adult patients with mantle cell lymphoma (MCL) who have not received treatment in the past (previously untreated). Rituximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Zanubrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. When zanubrutinib is used in MCL, the current standard of care is to continue administering the drug indefinitely until disease progression. This continuous treatment comes with clinical as well as financial toxicity, which could be especially detrimental in older patients. For patients who achieve a CR after initial zanubrutinib plus rituximab therapy, it may be safe and equally effective to stop treatment and restart zanubrutinib upon disease progression rather than continuing indefinitely in previously untreated older adult patients with MCL.

This phase III trial studies the side effects of inotuzumab ozogamicin and how well it works when given with frontline chemotherapy in treating patients with newly diagnosed B acute lymphoblastic leukemia. Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a chemotherapy drug called ozogamicin. Inotuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD22 receptors, and delivers ozogamicin to kill them. Chemotherapy drugs, such as [intervention], 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. Giving inotuzumab ozogamicin with chemotherapy may work better in treating young adults with B acute lymphoblastic leukemia.
