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 stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Gilteritinib is in a class of medications called kinase inhibitors. It works by blocking the action of a certain naturally occurring substance that may be needed to help cancer cells multiply. This study may help doctors find out if these different approaches are better than the usual approaches. To decide if they are better, the study doctors are looking to see if the study drugs lead to a higher percentage of patients achieving a deeper remission compared to the usual approach.

This phase II MyeloMATCH treatment trial compares cytarabine with daunorubicin versus cytarabine with daunorubicin and venetoclax versus venetoclax with azacitidine for the treatment of younger patients with intermediate risk acute myeloid leukemia (AML). Cytarabine is a drug that inhibits some of the enzymes needed for deoxyribonucleic acid (DNA) replication and repair and can slow or stop the growth of cancer cells. Daunorubicin is a drug that blocks a certain enzyme needed for cell division and DNA repair, and it may kill cancer cells. 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. Azacitidine is a drug that interacts with DNA to activate tumor-suppressing genes, resulting in an anti-tumor effect. Adding venetoclax to cytarabine and daunorubicin, and adding venetoclax to azacitidine, may work better than the usual treatment of cytarabine with daunorubicin alone. To decide if they are better, the study doctors are looking to see if venetoclax increases the rate of elimination of AML in participants by 20% or more compared to the usual approach.

Heart disease is the leading cause of death for men, women, and people of most racial and ethnic groups in the United States. This clinical trial will test if screening and early treatment of mild heart disease works. PRE-EMPT will screen individuals at low 10-year risk of heart disease with heart disease risk factors to identify those who already have early cholesterol build up, also called "plaque", in their heart arteries. It consists of two phases: 1. A Screening Study - Participants will be assessed for plaque by one or both of these scans. - Coronary Artery Calcium (CAC) Scan: A CT scan that looks for calcium or plaque in heart arteries. - Coronary CT Angiography (CCTA) Scan: A CT scan that uses contrast dye to create detailed 3D pictures of heart arteries to look for plaque. 2. A Treatment Trial (approximately 1,500 participants) - Based on the results of the CCTA, participants may be randomized into a two-year trial to test medications aimed at reducing or stabilizing plaque. Participants will have a 1 in 4 chance of receiving only placebo, and a 3 in 4 chance of receiving at least one active medication. Participants will take two pills once a day-either both active medications, one active and one placebo, or both placebos. - Rosuvastatin 20 mg: a cholesterol-lowering medicine - Colchicine 0.5 mg: a medication that lowers inflammation Everyone in the trial will be given information and advice on heart-healthy diet and lifestyle. Participants will have up to two in-person visits for the screening study, then phone visits for the Treatment Trial at the beginning, 3 months, 12 months and 24 months when they will also have an in-person visit for a CCTA Scan. Participants will have blood drawn using an at-home collection device mailed to their home at the beginning, 3 months, and end of the study.

This single arm study is designed to demonstrate the feasibility of a radically different approach for an exceptionally high-risk subset of MES with widely metastatic disease (WMES). We incorporate the use of evolutionary principles that apply to species and population dynamics as related to adaptation and extinction to populations of cancer cells that similarly adapt and that we are attempting to make extinct, resulting in a cure for the patient. Such principles include an initial intense first strike to deplete the bulk of the cancer cells, followed by a series of sequential second strikes towards eliminating residual, resistant populations, followed by a prolonged period of maintenance chemotherapy to eliminate any remnant cells, using agents generally regarded to be active against newly diagnosed ES.

Immunoglobulin A nephropathy (IgAN) is a kidney condition. It happens when the body's immune system creates groups of proteins (called immune complexes) that build-up in the kidneys causing swelling (inflammation). Over time, this inflammation may lead to kidney damage and cause the kidneys to no longer work properly. The main aim of this study is to check how well mezagitamab changes protein levels in the urine (proteinuria) compared to placebo in adults with primary IgAN. A placebo looks like medicine but doesn't have any active ingredients in it. Other aims are to check how safe mezagitamab is and how well participants with primary IgAN can tolerate it compared to placebo, and to find out if and how well mezagitamab continues to maintain kidney function over the long term compared to placebo. Participants will be placed in 1 of the 2 treatment groups; the main group and the open-label group. In the main group, participants will be placed by chance in either the mezagitamab or placebo treatment group at a 2:1 ratio. This means that out of 3 participants, 2 will receive mezagitamab and 1 will receive placebo. Participants can be in the study for 2 years (104 weeks). Participants will receive study treatment for about half a year (22 weeks) and then be observed for the remainder of the study (about 1.5 years). During observation, participants will continue to have check-ups about every month. In the open-label group, a small number of participants who either have lower levels of protein in their urine or have kidneys that do not filter the blood well, will receive mezagitamab treatment. This will include participants who have previously received mezagitamab in another study, TAK-079-1006. Every participant will receive mezagitamab in the same way as those in the main group receiving mezagitamab. During the study, participants will visit their study clinic several times.
