The purpose of this study is to get feedback on an existing augmented reality (AR) software developed by researchers at Wayne State University (phase I) and then use the refined software, along with Prolonged Exposure (PE) therapy to treat Veterans and military personnel with posttraumatic stress disorder (PTSD).

AR involves wearing goggles through which you can see the real world, however virtual objects can be added to the environment (for example, like in the popular phone game Pokemon Go).

The technology was originally designed to help first responders, specifically police and firefighters, to overcome their avoidance of normal life situations caused by their trauma experience and PTSD. This includes a crowded party, a grocery store, a police roll call room and a fire station. This technology is now being expanded to include other common scenarios that military personnel and Veterans with PTSD may avoid.

This study will occur in 2 phases. Phase 1 will focus on getting feedback on the AR program from people who have completed PE therapy before to refine the technology. In phase 2, 40 Veterans and military personnel will be randomly selected to receive PTSD therapy + the refined AR technology or PE therapy alone.

This study is open to Veterans and active duty military personnel. All study activities will take place at the Ralph H. Johnson VA Health Care System and surrounding community-based outpatient clinics. This study is not open to civilians/non military personnel at this time.

This is a research study involving an investigational drug called RT234. RT234 is being developed to treat pulmonary arterial hypertension (PAH). Eligible subjects must have a confirmed diagnosis of PAH and be on stable disease-specific PAH background therapy. The purpose of this study is to collect more information about the ability of RT234 to improve exercise capacity and safety of RT234 for the treatment of pulmonary arterial hypertension. The total duration of participation in the study, including screening, will be up to 4 study visits and a follow-up telephone call, over a period of up to 14 weeks. Up to 60 subjects will take part in this study.

This is a randomized, double-blind, placebo-controlled clinical study to evaluate the safety and efficacy of 2 doses of AP01 versus placebo on top of standard of care in subjects with Progressive Pulmonary Fibrosis (PPF) over 52 weeks. Subjects will participate in the study for up to 58 weeks, inclusive of a Screening Period of up to 4 weeks, a 52-week Treatment Period, and a 2-week Follow-up Period that includes a Follow-up telephone call (TC) 2 weeks post final dose. Up to 300 eligible subjects will be randomized in a 2:1:2 ratio to 1 of 3 treatment arms: AP01 100 mg twice daily (BID), AP01 50 mg BID, or placebo BID (8 mL; two 4 mL blow-fill-seal [BFS] ampoules BID).
