A Study to Learn More About the Long-term Safety and Effectiveness of Molidustat as a Treatment for Japanese Men and Women With Renal Anemia

In this study, the researchers want to learn more about the safety and effectiveness of Molidustat in Japanese men and women who have renal anemia, a condition in which the kidneys do not make enough of a hormone that helps the body make new red blood cells. In previous clinical trials with a small number of participants, several important adverse events were observed. The researchers in this study want to know how many patients also have these adverse events under the real world, and if the number of the red blood cells will be increased after the treatment of Molidustat. The researchers will collect the participants' health information from their medical records and their regular check-ups for up to 2 years. The data from this study will be submitted to the health authority in Japan in accordance with the local regulation.

A Study of Roxadustat to Treat Anemia in Children and Teenagers With Chronic Kidney Disease

Roxadustat is a licensed medicine to treat anemia in adults with chronic kidney disease (CKD). Anemia is a low level of red blood cells. Current treatment for anemia is to have injections of medicines called erythropoietin stimulating agents (also known as ESAs) to help the bone marrow make more red blood cells. These are often given together with iron. This treatment is also available to children and teenagers with CKD. However, there are some safety concerns with ESAs. Also, as roxadustat is taken orally, this may be another option for treating anemia in children and teenagers with CKD. In this study, children and teenagers with CKD and anemia will take roxadustat for up to 52 weeks to treat their anemia. The main aim of the study is to learn how roxadustat affects anemia in children and teenagers with CKD. This is an open-label study which means the children and teenagers in the study and the clinic staff know they will be taking roxadustat. In this study, the children and teenagers with CKD who need treatment for anemia can take part. Those currently being treated with an ESA will be switched to roxadustat. Those who have not been treated with an ESA can start on roxadustat straight away. All children and teenagers in the study will take roxadustat 3 times a week for up to 52 weeks (1 year). They will start on a fixed dose of roxadustat for 4 weeks. Blood samples will be taken regularly to check hemoglobin levels. The roxadustat dose may be changed if the blood levels of hemoglobin are too high, too low, or change too quickly. After 4 weeks the dose may be changed, if needed, to keep blood levels of hemoglobin in the blood to just below the normal range. Firstly, teenagers will take roxadustat. 10 teenagers will take their fixed dose of roxadustat for 4 weeks. They will give blood samples to help the researchers work out the most suitable dose for the rest of the teenagers in the study. When the rest of the teenagers start taking roxadustat at the most suitable dose for teenagers, 10 children will take roxadustat for 4 weeks. These 10 children will give blood samples to help the researchers work out the most suitable dose for the rest of the children in the study. Then, the rest of the children will take roxadustat at the most suitable dose for children. There will be many clinic visits during the study. Overnight hospital stays are not expected. There will be 1 visit every 2 weeks for the first 4 weeks of taking roxadustat, then every 4 weeks until the end of treatment. Finally there is 1 visit 4 weeks after treatment has finished. During most visits, the children and teenagers will have their vital signs checked (blood pressure, body temperature and heart rate). Fluid status (how much water is in the body) will also be checked for those who need dialysis. The children and teenagers will also have blood tests and the study doctors will check for any medical problems. The children and teenagers will have a medical examination before their first dose of roxadustat and again at about 24-week (6-month) and 52-week (13-month) visits. They will have an electrocardiogram (ECG) before their first dose of roxadustat and again at the 12-week, 24-week, 36-week, and 52-week visit. They will also have urine tests at the 4-week, 24-week and 52-week visits. At the 52-week visit, the children and teenagers will also have blood tests for hemoglobin and iron levels. The study doctors will also check for any medical problems.

Iron Isomaltoside for the Treatment of Anemia in Peritoneal Dialysis Patients

This is a prospective multicenter randomized controlled clinical study. The goal of this clinical trial is to learn if intravenous iron isomaltoside injection use is equally effective and safe for the treatment of renal anemia in peritoneal dialysis patients compared with oral ferrous succinate tablets. The main questions to answer are: * Changes in hemoglobin concentration from baseline to week 8 after the use of single dose intravenous iron isomaltoside injection in peritoneal dialysis patients with renal anemia. * If intravenous iron isomaltoside injection use is equally effective and safe for the treatment of renal anemia in peritoneal dialysis patients compared with oral ferrous succinate tablets. Participants will: * be randomized 1:1 to two groups, either Iron isomaltoside Group (Group A, experimental group) or Ferrous succinate Group (Group B, control group). * Patients in Iron isomaltoside Group will receive a single dose of intravenous iron isomaltoside injection, the dose of which is set at 1000 mg. Patients in Ferrous succinate Group will receive ferrous succinate treatment orally given as 200mg twice a day for 8 weeks (containing iron element 7840mg in total). * Patients will be followed up for 8 weeks.
