Familial hemolytic anemia

This study tests a drug called SIL-8301 (senicapoc) in 105 adults with sickle cell disease who have low hemoglobin but few pain crises. Participants take the drug or a placebo daily for 24 weeks, along with their usual hydroxyurea. The main goal is to see if the drug raises hemog…

This early-phase trial tests an oral drug called ATL-001 (ciclopirox) in 6 adults with congenital erythropoietic porphyria (CEP), a rare condition that causes severe skin damage from sunlight. The study measures whether the drug reduces skin lesions, fatigue, and other symptoms o…

This early study tests whether zoledronic acid, a drug usually used for bone health, can help people with a rare inherited anemia called congenital dyserythropoietic anemia (CDA). Only 2 adults with CDA who have low hemoglobin or need regular transfusions will receive 4 doses of …

This early-stage study tests a new drug called APG-5918 in healthy volunteers and people with anemia (low red blood cells). The main goal is to check safety and how the body handles the drug, while also seeing if it can raise hemoglobin levels. About 105 participants will take pa…

This study aims to learn more about rare disorders that affect how the body processes chemicals called pyrimidines and purines. These disorders can cause problems in the brain, blood, kidneys, and immune system, ranging from mild to life-threatening. Researchers will compare test…

This study is a registry for people with Congenital Dyserythropoietic Anemia (CDA), a rare blood disorder. Researchers will collect medical information and blood or bone marrow samples over many years to better understand how the disease progresses, its causes, and how it affects…

This registry collects information from people with inherited retinal diseases, like retinitis pigmentosa and Stargardt disease. Participants share their symptoms, family history, and genetic test results online. The goal is to help researchers understand these rare diseases and …

This study follows 1,500 people with porphyria over many years to learn how the disease progresses, what symptoms appear, and how it affects pregnancy and lifespan. Researchers will collect medical records and lab results to create a clearer picture of the condition. No new treat…

This study looks at whether doctors at Siriraj Hospital follow a new guideline for treating anemia in patients before major surgery. Anemia is common in surgical patients and can lead to more blood transfusions and worse outcomes. The researchers will track 93 anemic patients to …

This study tracks 200 people with ultra-rare glycogen storage diseases (GSDs) like types 0a, 0b, VII, X, XII, XIII, XV, PRKAG2 syndrome, and Danon disease. Researchers will collect medical records and other data to see how these conditions progress over time. No treatments or dru…

This study is observing 1000 adults having moderate- to high-risk surgery to see if the type and severity of anemia they have before surgery affects their risk of complications like heart injury, kidney injury, or stroke. Researchers will compare patients with iron-deficiency ane…

This study is for people with sickle cell disease or other rare anemias. Researchers want to use advanced genetic and blood tests to better understand each person's condition. The goal is to make diagnosis more precise so that treatments can be tailored to each patient. About 200…

This study aims to better understand how the spleen filters and responds to abnormal blood cells in various diseases. Researchers will collect spleen tissue and blood from 100 adults undergoing planned splenectomy. By perfusing the spleen in the lab, they hope to uncover its role…
