NCT05756985
To collect and preserve glioblastoma tissue during standard of care tumor resection surgery and blood for future molecular and genetic testing. Tissue for research will be collected from three different regions within the same tumor to study how these regions differ in their structure, DNA, and RNA and also to compare the data obtained from this testing to imaging data found in the medical record. The goal of this study is to help us better understand what the glioblastoma tumor tissue looks like and how it functions. This understanding can lead to new therapies for the treatment of glioblastoma in the future.
NCT07160205
The goal of this clinical trial is to learn about how an umbilical cord lining-derived stem cell (ULSC) product performs when treating Dermatomyositis/Polymyositis (DM/PM), also known as idiopathic inflammatory myopathy (IIM) in adults. It will assess safety and efficacy in relieving symptoms of DM/PM with ULSC administered in three intravenous (IV) doses of 150 million cells per dose. The main questions that this study plans to answer are: * Is ULSC as safe as placebo (a look-alike saline without cells) in repeated IV infusion? * Does ULSC improve symptoms of DM/PM after three doses? Researchers will compare ULSC to placebo and evaluate changes from baseline (before first dose) to after each dose and after all three doses are completed per treatment study period. * For participants undergoing steroid (e.g., prednisone) therapy for DM/PM, does ULSC allow their steroid dose to be reduced? Does ULSC reduce need for rescue therapy? Participants will have been diagnosed with either DM or PM: * Diagnosed according to the EULAR/ACR 2017 Classification Criteria for idiopathic inflammatory myositis (IIM), which includes DM and PM. * Positive for myositis-associated antibody or undergone evaluation to exclude mimics. Participants in this study will: * Participate for total of 25 months with 15 in-person clinic visits and 8 virtual visits on phone or video call. * Receive both ULSC and placebo for a total of 6 IV infusions (260 mL) 3 months apart. * Receive 3 doses of ULSC and 3 doses placebo in either of two sequences, as assigned: ULSC first and placebo second, or placebo first and ULSC second. * If undergoing steroid therapy, will have steroid dose taper prescribing lower doses starting two weeks after the second infusion. * Return for follow-up visits after each dose and up to 12 months after final dose. * Have follow-ups including self-reported questionnaires, physical exam, muscle strength and endurance tests, blood tests, pulmonary function tests, and other assessments.
