Study of the CHK1 Inhibitor BBI-355, an ecDNA-directed Therapy (ecDTx), in Subjects With Tumors With Oncogene Amplifications
Recruiting
BBI-355 is an oral, potent, selective checkpoint kinase 1 (or CHK1) small molecule inhibitor in development as an ecDNA (extrachromosomal DNA) directed therapy (ecDTx). This is a first-in-human, open-label, 3-part, Phase 1/2 study to determine the safety profile and identify the maximum tolerated dose and recommended Phase 2 dose of BBI-355 administered as a single agent or in combination with select therapies.

Non-Inferiority Trial of TrIGR for PTSD
Recruiting
Trauma-related guilt is common and impairing among trauma survivors, particularly among Veterans with posttraumatic stress disorder (PTSD). The investigators' work shows that a brief treatment targeting trauma-related guilt, Trauma Informed Guilt Reduction Therapy (TrIGR), can reduce guilt and PTSD and depression symptoms. Whether TrIGR is no less effective than longer, more resource heavy PTSD treatments disseminated by by VA, like cognitive processing therapy (CPT), is the next critical questi... Read More

FORAGER-1: A Study of LOXO-435 (LY3866288) in Participants With Cancer With a Change in a Gene Called FGFR3
Recruiting
The main purpose of this study is to learn more about the safety, side effects, and effectiveness of LOXO-435 by itself or when it is combined with other standard medicines that treat cancer. LOXO-435 may be used to treat cancer of the cells that line the urinary system and other solid tumor cancers that have a change in a particular gene (known as the FGFR3 gene). Participation could last up to 30 months (2.5 years) and possibly longer if the disease does not get worse.

Empathic Communication Skills (ECS) Training
Recruiting
Research indicates that perceived stigma within medical encounters is prevalent and problematic for lung cancer patients' well-being and quality of cancer care. Promoting empathic communication appears to be a potentially effective intervention target to help reduce patients' perceptions of stigma within clinical encounters; however, no formal trainings exist that focus on teaching empathic communication to oncology care providers (OCPs). Building upon favorable findings from a prior R21 (R21CA2... Read More
