Functional and Cognitive Rehabilitation of Hoarding Disorder
Recruiting
Hoarding Disorder (HD) is serious and disabling in Veterans. Present in up to 7% of Veterans and even higher symptom rates in older Veterans; HD contributes to functional impairment and poor quality of life. Cognitive Rehabilitation and Exposure/Sorting Therapy (CREST) has shown promising functional improvement and symptom reduction. To reduce burdens and barriers to implementation of CREST, the proposed project will individualize CREST based on cognitive testing and participant preferences, pro... Read More

ATHN Transcends: A Natural History Study of Non-Neoplastic Hematologic Disorders
Recruiting
In parallel with the growth of American Thrombosis and Hemostasis Network's (ATHN) clinical studies, the number of new therapies for all congenital and acquired hematologic conditions, not just those for bleeding and clotting disorders, is increasing significantly. Some of the recently FDA-approved therapies for congenital and acquired hematologic conditions have yet to demonstrate long-term safety and effectiveness beyond the pivotal trials that led to their approval. In addition, results from... Read More

Gene Modified Immune Cells (IL13Ralpha2 CAR T Cells) After Conditioning Regimen for the Treatment of Stage IIIC or IV Melanoma or Metastatic Solid Tumors
Recruiting
This phase I trial studies the side effects and best dose of modified immune cells (IL13Ralpha2 CAR T cells) after a chemotherapy conditioning regimen for the treatment of patients with stage IIIC or IV melanoma or solid tumors that have spread to other places in the body (metastatic). The study agent is called IL13Ralpha2 CAR T cells. T cells are a special type of white blood cell (immune cells) that have the ability to kill tumor cells.
