Filter by:The goal of this clinical trial is to Investigate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of HMB-001 in Participants with Glanzmann Thrombasthenia. The main questions it aims to answer are: - Parts A, B, and C: To determine the safety and tolerability of HMB-001 - Part A: To establish the dose level(s) and dosing interval(s) of HMB-001 to be investigated in Parts B and C - Parts B and C: To estimate the ability of HMB-001 to prevent the number and severity of bleeds Part A will assess differing singular doses of HMB-001 in small groups of participants. The dose administered to a newly enrolled participant (or groups of participants) may only increase if analysis of data from previous dosing shows it is safe to do so. The planned duration of participation in Part A is approximately 6 months, which consists of a Screening Period, an optional Run-in Observation Period, and a follow-up period of 8 weeks. Part B is similar to Part A as it involves testing different dose levels of HMB-001 in small groups of participants. However, in Part B, HMB-001 is given multiple times over a 3-month period, either weekly, every 2 weeks, or every 4 weeks. Part B consists of a Screening Period, a Run-in Observation Period, a 3-month Treatment Period, and a Safety Follow-up following the last dose of HMB-001. Part C is open to participants from Part B and consists of approximately a 9-month Treatment Period and a Safety Follow-up following the last dose of HMB-001.
In Willebrand disease, there is currently no test available to identify non-invasively patients with a high risk of bleeding from angiodysplasias The study propose to use a sublingual capillary bed analysis by video-microscopy, a sensitive, reproducible and non-invasive technique, to assess whether sublingual capillary density is predictive of hemorrhagic risk for patients with von Willebrand disease.
This is a study to collect the outcomes of stem cell transplantation for patients with hematologic diseases other than cancer.
Blood contains red blood cells, white blood cells, and platelets, as well as a fluid portion termed plasma. We primarily study blood platelets, but sometimes we also analyze the blood of patients with red blood cell disorders (such as sickle cell disease), white blood cell disorders, and disorders of the blood clotting factors found in plasma. Blood platelets are small cell fragments that help people stop bleeding after blood vessels are damaged. Some individuals have abnormalities in their blood platelets that result in them not functioning properly. One such disorder is Glanzmann thrombasthenia. Most such patients have a bleeding disorder characterized by nosebleeds, gum bleeding, easy bruising (black and blue marks), heavy menstrual periods in women, and excessive bleeding after surgery or trauma. Our laboratory performs advanced tests of platelet function and platelet biochemistry. If we find evidence that a genetic disorder may be responsible, we analyze the genetic material (DNA and RNA) from the volunteer, and when possible, close family members to identify the precise defect.
