Transthyretin Amyloid Cardiomyopathy (ATTR-CM) is a serious and life-threatening condition where a protein called transthyretin (TTR) misfolds and builds up as amyloid fibrils in the heart muscle. This buildup causes the heart to become stiff, leading to restrictive cardiomyopathy and progressive heart failure. There are two forms of ATTR-CM: a hereditary or 'variant' form (vATTR-CM) caused by a gene mutation, and a 'wild-type' form (wtATTR-CM) which is associated with aging. Because its symptoms can be similar to other heart conditions, ATTR-CM is often diagnosed late. However, recent advances in medical imaging are helping doctors to identify the disease earlier. Acoramidis is a new medication designed to treat ATTR-CM. It works by stabilizing the TTR protein, preventing it from misfolding and forming the harmful amyloid deposits. Acoramidis has been shown to be effective and safe in a major clinical trial (the ATTRibute-CM study), which led to its approval for use in both the United States and Europe. While clinical trials provide valuable information, data on how a new medicine performs in everyday clinical practice is also very important. This type of information is called real-world evidence. Currently, there is limited real-world information about the use of acoramidis. This study, called ACO-REAL, is an observational study, which means researchers will observe patients who are receiving acoramidis as part of their normal clinical care, without introducing any experimental interventions. The study will take place in approximately 20 European countries and aims to enroll up to 2,000 adults who have been diagnosed with either wild-type or variant ATTR-CM and are starting treatment with acoramidis. This includes patients who have not been treated for ATTR-CM before, as well as those who have been treated with other therapies. The main goals of the study are to understand the characteristics of patients being treated with acoramidis and to document how the treatment is used in routine medical practice. The study will also collect information on the safety of acoramidis. Furthermore, researchers will assess how the treatment affects patients' heart function, their functional capacity (such as their ability to walk), their overall health status, and their quality of life. The study will also track how often patients need to use healthcare resources like hospitals or emergency rooms. This information will help to improve the understanding and management of ATTR-CM in a real-world setting, ultimately aiming to optimize care for patients with this progressive disease.Show more

IRIS-CKD is a two-program implementation study to improve guideline-recommended screening and treatment of chronic kidney disease (CKD) in individuals with type 2 diabetes (T2D) in the United States.

Transthyretin (TTR) is a protein made by the liver that helps transport thyroid hormone and vitamin A in the blood. In some people, this protein breaks down and forms harmful clumps called amyloid. TTR amyloid gets deposited in the heart wall and stops it from pumping blood properly, which may lead to heart failure. The breakage in TTR protein can be age-related (wild-type ATTR-CM), or genetic (variant ATTR-CM). The study drug, acoramidis, works by attaching itself to the TTR protein, making TTR more stable and less likely to break down and form amyloid (clumps). This helps to slow down the progression of the disease, improve heart function, and increase the TTR levels in the blood. Acoramidis is an approved treatment for wild-type or variant ATTR-CM in Europe and the United States. Tafamidis is another drug that stabilizes TTR and prevents it from breaking down. In this study, acoramidis will be studied in participants with ATTR--CM who were previously treated with tafamidis. The main purpose of this study is to assess the change in blood TTR levels after participants are switched from tafamidis to acoramidis. This will be studied to understand if acoramidis causes an increase in blood TTR levels beyond the levels achieved with tafamidis. For this, the researchers will measure the change in the levels of TTR protein in participants' blood after 6 months of the treatment with acoramidis, or earlier if a participant stops the treatment before reaching that six-month mark. All participants will continue taking tafamidis during the screening period. In the treatment period of the study, participants will take acoramidis as two tablets twice daily by mouth, for up to 6 months. At the start of this study, the study doctors will review each participant's medical history and check their overall health. The study doctors will perform electrocardiograms (ECG), and measure blood pressure and heart rate. Researchers will also take blood and urine samples from the participants to measure levels of TTr, NT-proBNP, hs-TnT, hs-CRP, RBP4, eGFR, creatinine, cystatin-C, UACR, and TSH at the start of the study, and at various time points thereafter (during the study) to assess heart, kidney and thyroid function. There will be a total of 9 study check-ins. Participants will visit the study site twice: at screening and at the end of treatment period. A study nurse will visit the participant's home 6 times, at the start of treatment, Weeks 1, 2, 3 and 4, then again at 3 months. The final check-in will be done by phone. The study doctors will monitor the health of the participants regularly for any medical problems during follow-up visits. Participants will know the treatment they will receive during the study. Each participant could be in the study for about 8 months.Show more

Transthyretin amyloid cardiomyopathy (ATTR-CM) is a progressive heart disease caused by the buildup of an abnormal protein, called transthyretin (TTR), in the heart. This buildup can make it harder for the heart to pump blood and may lead to worsening symptoms over time. Acoramidis is a medicine approved for the treatment of adults with wild-type or hereditary (variant) ATTR-CM. While its benefits have been demonstrated in clinical trials, more information is needed about how it is used and how patients do in everyday medical practice. The MOSAIC-TTR study is an observational study in France. Participants will receive acoramidis as part of their usual medical care. No experimental treatments or additional medical procedures will be required. The study will collect information directly from participating hospitals and from the Healthcare European Amyloidosis Registry (HEAR; NCT05101304). The main goal of the study is to understand how patients' quality of life, daily functioning, and overall well-being change during the first 12 months of treatment with acoramidis, using questionnaires completed by the patients themselves. The study will also collect information about the characteristics of patients receiving acoramidis, how the medicine is used in routine clinical practice, and its safety and tolerability. The information collected will help improve the understanding of ATTR-CM and may help improve the care of people living with this condition.Show more

Researchers want to learn more about the use of larotrectinib as a real-world treatment for tropomyosin receptor kinase fusion cancer, also called TRK fusion cancer. In people with TRK fusion cancer, a gene called neurotrophic TRK, (NTRK) joins or "fuses" with another gene. This creates a protein known as a fusion protein, which can cause cancer cells to grow. The study treatment, larotrectinib, is already available for doctors to prescribe to patients with TRK fusion cancer. Larotrectinib works by blocking TRK genes in cancer cells which helps stop the cancer from growing. In this study, the researchers want to learn more about the safety and effectiveness of larotrectinib in adults and children with advanced or recurrent TRK fusion cancer. This means that their cancer has spread from where it started to other areas of the body, or the cancer has come back after a period of time. To answer this question, the researchers will collect information from patients who are taking larotrectinib as prescribed by their doctors. The researchers will learn what adverse events the patients are having. An adverse event is any medical problem that a patient has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments. The study will include patients of all ages with TRK fusion cancer. In this study, there will be no required tests or visits to a study site. Instead, the researchers will collect information from: * the patients' medical records * interviews with the patients or their parents or guardians * the patients' visits to their doctor as part of their usual care The researchers will collect information about the adults for up to about 2 years and about the children for up to about 8 years.Show more
