StandUPTV Habits: Feasibility Trial for Maintaining Reductions in Sedentary Screen Time
Recruiting
Our goal in this study is to further refine StandUPTV, an application designed to reduce SST in adults in our first study (ASU IRB # STUDY00012109), for the StandUPTV Habits program. This program aims to establish a non-sedentary habit triggered by an alert from the StandUPTV application after participants engage in approximately 30 minutes of SST in the evening.

Accountability Support Through Peer-Inspired Relationships and Engagement (ASPIRE) Trial
Recruiting
This project aims to test the efficacy of a text message intervention, ASPIRE, designed to address cognitive and behavioral elements and modify exposure to peers that influence drinking behaviors. Young adults who are contemplating reducing their drinking will be recruited from a national sample and randomized to ASPIRE versus a text message intervention focused solely on cognitive and behavioral elements. We will measure effectiveness at 3, 6, and 12 months, study mechanisms driving behavior ch... Read More

A Research Study Looking at Long-term Treatment With Etavopivat in People With Sickle Cell Disease or Thalassaemia
Recruiting
Etavopivat is a new medicine under development for treating blood disorders like sickle cell disease and thalassaemia. Sickle cell disease and thalassaemia are inherited blood disorders that affect haemoglobin. Haemoglobin is the protein that carries oxygen through the body. This study is looking into how safe treatment with etavopivat is and how well it works over a long period of time. The study will last for up to 264 weeks, but it will end earlier if etavopivat is approved in the participant... Read More

This phase II trial compares the effectiveness of adding BMX-001 to usual symptom management versus usual symptom management alone for reducing oral mucositis in patients who are receiving chemoradiation for head and neck cancer. Oral mucositis (inflammation and mouth sores) is a common side effect of chemoradiation that can cause pain and difficulty swallowing. Usual management of these side effects typically consists of using mouth rinses and pain medications during treatment and for several w... Read More
