Thrombotic Microangiopathies clinical trials at UCSF

3 in progress, 2 open to eligible people

Showing trials for
  • Ravulizumab in Pediatric Participants With HSCT-TMA

    open to eligible people ages up to 17 years

    This study will evaluate the safety, efficacy, pharmacokinetics, and pharmacodynamics of ravulizumab administered by intravenous infusion to pediatric participants, from 1 month to < 18 years of age, with HSCT-TMA. The treatment period is 26 weeks, followed by a 26-week off-treatment follow-up period.

  • TRANSPIRE: Lung Injury in a Longitudinal Cohort of Pediatric HSCT Patients

    open to eligible people ages up to 24 years

    Hematopoietic stem cell transplant (HSCT) is an effective but toxic therapy and pulmonary morbidity affects as many as 25% of children receiving transplant. Early pulmonary injury includes diffuse alveolar hemorrhage (DAH), thrombotic microangiopathy (TMA) interstitial pneumonitis (IPS) and infection, while later, bronchiolitis obliterans is a complication of chronic GVHD associated with severe morbidity and mortality. Improved diagnosis and treatment of pulmonary complications are urgently needed as survival after HSCT improves, and as HSCT is increasingly used for non-malignant disorders such as sickle cell disease. Currently, there are large and important gaps in the investigator's knowledge regarding incidence, etiology and optimal treatment of pulmonary complications. Moreover, young children unable to perform spirometry are often diagnosed late, and strategies for monitoring therapeutic response are limited. This is a prospective multi-institutional cohort study in pediatric patients undergoing allogeneic hematopoietic stem cell transplantation (alloHSCT). Assembly of a large prospective uniformly screened cohort of children receiving HSCT, together with collection of biological samples, will be an effective strategy to identify mechanisms of lung injury, test novel diagnostic strategies for earlier diagnosis, and novel treatments to reduce morbidity and mortality from lung injury after transplant.

  • Defibrotide Prophylaxis of Transplant Associated-Thrombotic Microangiopathy for Neuroblastoma

    Sorry, not yet accepting patients

    This phase II trial tests how well defibrotide works in preventing transplant-associated thrombotic microangiopathy (TA-TMA) in patients with high-risk neuroblastoma undergoing tandem transplants (hematopoietic stem cell transplant [HSCT]). TMA is a potential life-threatening complication of stem cell transplant. TMA is a possible side effect of the chemotherapy (conditioning regimen) patients receive to help treat high-risk neuroblastoma, because these medicines can sometimes damage the blood vessel walls in the body. This damage leads to formation of tiny blood clots in organs, especially the kidney. This then causes organ damage and leads to problems with how they function. This study may help researchers learn how defibrotide may help prevent TMA before it starts, or help treat it once it starts among patients with high-risk neuroblastoma undergoing tandem transplants.
