Elucidating Shared Mechanisms Contributing to NAFLD and PsA Disease Severity With Guselkumab Therapy
Recruiting
While many studies examine Nonalcoholic fatty liver disease (NAFLD), little is known about its progression to high-risk nonalcoholic steatohepatitis (NASH) in PsA patients. Shared disease mechanisms may explain the increased severity in PsA. This study involves two visits from PsA patients with NAFLD and active disease signs (e.g., swollen joint, enthesitis, or psoriatic plaque). It aims to assess the impact of biological therapies on liver disorders, joints, and skin in PsA patients.

Modular Trial of sEphB4-HSA in EphrinB2-High Solid Tumors
Recruiting
Patients with solid tumors that have high expression levels of EphrinB2 are treated with regimens that include EphrinB2 inhibitor, sEphB4-HSA. The primary objective of this study is to demonstrate additive therapeutic benefit for sEphB4-HSA. The secondary objectives are to determine whether the sEphB4-HSA containing regimen is safe and whether the oncological endpoints of importance in each cohort improve as a result of treatment with sEphB4-HSA containing regimen relative to a predefined thresh...

The Effect and Safety of Anti-inflammatories and Dextrose Prolotherapy Injections in Treating Knee Osteoarthritis
Recruiting
Our purpose is to expand upon the results of the pilot study performed at David Grant Medical Center (DGMC) which showed that concomitant non-steroidal NSAID use in adults with knee osteoarthritis (OA) undergoing a three-shot dextrose prolotherapy (DPT) injection series did not negate the efficacy of DPT. Additionally, it showed that giving both treatments simultaneously is safe and efficacious. The small sample size and design of the pilot study limited the conclusions that can be drawn on the...
