Study of KYV-101 Anti-CD19 CAR T Therapy in Adult Dermatomyositis
Recruiting
The goal of this clinical trial is to characterize to understand the effects of a type of cell therapy called Chimeric Antigen Receptor T lymphocyte (CAR T) therapy in adult patients with the autoimmune disease dermatomyositis. This study will utilize a technology that modifies a type of white blood cell called the cytotoxic T lymphocyte-this T cell normally functions in the immune system to kill infected or potentially harmful cells in the body. In CAR T therapy, the patients' white blood cells... Read More

A Hybrid 1 Effectiveness-Implementation Trial of Partner-Assisted Prolonged Exposure for PTSD
Recruiting
PTSD occurs in up to 17% of post-9/11 US Service Members and is associated with long-term functional impairment, family problems, unemployment, and suicidality. Trauma-focused therapies (TFTs), such as Prolonged Exposure (PE), result in significant relief for many. Yet, TFTs are not equally effective for everyone. An important minority (\~40%) will retain their PTSD diagnoses after treatment, and many discontinue treatment prematurely, especially post-9/11 Service Members. TFTs are also more eff... Read More

This is a single-arm extension study to investigate the long-term safety, tolerability, and efficacy of lunsekimig in adult participants with inadequately controlled CRSwNP who have completed a previous lunsekimig CRSwNP clinical study (also referred to as the parent study ACT18207). The study duration will be up to approximately 56 weeks per participant, 52 weeks of treatment period, and 4 weeks of follow-up.

Molecular Analysis for Precision Surgery in Thyroid Cancer Trial
Recruiting
Ideal surgical extent for differentiated thyroid cancer remains unclear. Routine use of molecular analysis in biopsy-proven thyroid cancer could provide important prognostic information to help guide extent of surgery - thyroid lobectomy versus total thyroidectomy. This is a pilot feasibility study for the use of routine molecular analysis in Bethesda V and VI thyroid cancers, with randomization of the intermediate-molecular risk subgroup to thyroid lobectomy and total thyroidectomy. The investi... Read More
