Clinical trials

Posttraumatic stress disorder (PTSD) is a common and debilitating mental illness. Current treatments for PTSD include psychotherapy and antidepressant medications. Many patients are unable to tolerate psychotherapy for PTSD and drop out of it. In addition, its effectiveness is limited. Up to 50 percent of patients who receive psychotherapy do not benefit from it. Antidepressant medications have only small benefits in PTSD. They also have unpleasant side effects that can make patients unwilling to take them. There is an urgent need to develop new treatments for PTSD that work and are well-tolerated. Silexan has the potential to provide an important alternative treatment for PTSD. Silexan is derived from lavender oil. It is taken orally in the form of capsules. It is currently available over-the-counter in 14 countries, including Australia and the United States. Previous research has shown that it is an effective treatment for anxiety disorders, including Generalized Anxiety Disorder. It is also well-tolerated by patients. The only side effects that have been identified so far are mild gastrointestinal symptoms (including burping and breath odour) and these are uncommon. The results of a small pilot study suggest that Silexan may also be effective and well-tolerated in PTSD. The STOP trial is a clinical trial that aims to investigate whether adding Silexan to treatment-as-usual improves PTSD symptoms in adults with PTSD. The trial will recruit 278 participants. Participants will be randomly assigned to take Silexan or a placebo (look-alike dummy pills) daily in addition to their usual medications for 12 weeks. The severity of their PTSD symptoms will be assessed prior to and at the end of this 12-week period. The STOP trial has the potential to obtain definitive evidence regarding whether Silexan helps treat symptoms of PTSD. If Silexan is found to be an effective treatment for PTSD, the pool of patients who could potentially benefit from this treatment includes any adults with PTSD. Silexan is already available over-the-counter at a relatively low cost so there will be few barriers to accessing this treatment.

In this project, researchers are exploring different ways to support the wellbeing and relationships of families with young children (0-12 years). People in regional and rural communities often live with the threat of bushfires, floods, drought, severe storms, and other extreme weather events. Some families have been affected by these disasters and are still trying to recover. Researchers will test two different ways of supporting families in regional and rural Victoria: Family Foundations (FF): An 8-session program to promote parent wellbeing, parenting partnerships, and communication. All parents/caregivers/parenting partners in the family participate in sessions delivered by a health professional online. Family Life Check-In: A brief 30-minute telephone call with a health professional to discuss family wellbeing and relationships, and identify any supports needed. The goal of this trial is to learn whether FF works to reduce mental health difficulties for regional and rural families. The main question it aims to answer is: Compared to Family Life Check-In, does Family Foundations lead to fewer mental health difficulties? Participants will: Complete an online survey before randomisation, after they have received FF or Family Life Check-In, and six months after starting the project. Take part in either Family Foundations or Family Life Check-In.
