This long-term study tests the safety and effectiveness of bitopertin (DISC-1459) in people with erythropoietic protoporphyria (EPP) or X-linked protoporphyria (XLP), rare conditions that cause severe pain from sunlight exposure. About 230 participants who previously took bitoper…

This Phase 3 trial tests whether bitopertin, a daily pill, can help people with erythropoietic protoporphyria (EPP) or X-linked protoporphyria (XLP) spend more time in sunlight without pain. About 183 participants aged 12 and older will take bitopertin or a placebo for 6 months. …

This study aimed to see if the drug bitopertin is safe for people with erythropoietic protoporphyria (EPP) or X-linked protoporphyria (XLP) who also have early signs of liver disease. Researchers planned to check for side effects and measure changes in protoporphyrin levels in bl…

This study tests whether giving extremely preterm babies less intravenous (IV) fat (lipids) can lower harmful bilirubin levels and protect their brain development. Bilirubin can build up in these tiny infants and cause hearing loss or long-term disabilities. Researchers will comp…

This study looks at a rare liver disease called PFIC, which causes severe itching and liver damage. Researchers compare patients who took the drug odevixibat to those who did not, using data from past studies and a patient registry. The goal is to see if odevixibat helps avoid li…

This study followed children and young adults with genetic liver diseases that cause bile buildup. The goal was to track how these diseases progress over time, including the need for liver transplants or other complications. No treatments were tested; the aim was simply to learn …

This study aims to find new biological markers (biomarkers) that can show how active acute porphyria is in the body and how well treatments are working. Researchers will study 50 people with confirmed acute porphyria to measure gene activity related to heme production and stress …

This study tests a new wireless sensor that continuously measures the light dose babies receive during phototherapy for jaundice. Currently, doctors check light levels only once a day with a handheld device, which can be inaccurate. The sensor aims to provide real-time data to en…

This study looks at whether people with Postural Orthostatic Tachycardia Syndrome (POTS) might also have a rare condition called acute hepatic porphyria (AHP), which can cause similar symptoms like rapid heart rate and abdominal pain. Researchers will test 70 adults with POTS usi…
