Alex’s Wish invests £10,000 towards a £228,562.51 grant

The investment is to address the use of testosterone as a treatment for Duchenne Muscular Dystrophy. Testosterone is sometimes given to patients with Duchenne Muscular Dystrophy (DMD) who take steroids.

The £228,562.51 grant from Duchenne UK will fund an extension to the current clinical trial studying the effects of the use of testosterone in DMD patients.

Steroids are part of the recognised standard of care in treating Duchenne Muscular Dystrophy (DMD). But long-term use of steroids causes a number of side effects including delayed puberty. Testosterone is sometimes given to make boys begin going through puberty. It may also have other benefits.

As the life expectancy of DMD patients increases, more young men are looking to establish relationships and lead independent adult lives. We are funding this research to ensure boys are given the correct hormonal treatment to allow them to develop properly.

These funds will support the clinical trial at the John Walton Muscular Dystrophy Research Centre (JWMDRC), led by Prof Volker Straub and Dr Claire Wood, treating 15 adolescents with DMD with testosterone to induce puberty.

As well as looking at the effect of testosterone on pubertal development, growth, muscle strength and function, bone mineral density and body composition, the trial is looking at the mood, quality of life and well-being of patients to assess their satisfaction with the benefits of the treatment compared to the side effects. The initial trial was funded by Duchenne Now.

Emily Crossley, co-founder and co-CEO of Duchenne UK said:

“This is an important study that could impact on the quality of life for young men with Duchenne Muscular Dystrophy. We would like to thank our partner charity, Duchenne Now for initiating this valuable project and we are pleased to be able to help fund the next stage.”

Emma Hallam, founder of Alex’s Wish said:

“Having a son approaching 13 years old who has Duchenne and is on daily steroids, I understand the impact of delayed puberty – especially its impact on muscle strength and bone density. I know how important it is that we understand the effects of Testosterone and Alex’s Wish fully supports this project. We are so thankful to our supporters for enabling us to invest in such an important project leading us to new treatments that could help improve well being and life expectancy.”

The grant, worth £228,562.51 will pay for the extension study of this trial to look at the longer term effects of testosterone treatment following earlier treatment to induce puberty. The extension study will investigate whether testosterone treatment to induce puberty will be enough to support long term testosterone production, or whether further treatment with testosterone is needed for patients on long-term steroids to keep producing testosterone, even if puberty was successfully induced.

If this study can prove that Testosterone for pubertal induction is an effective treatment to address delayed puberty, then we hope to see
the use of testosterone included in the standards of care for adolescents with DMD. This project is another example of how the Duchenne Community come together as it was funded by Duchenne UK – Alex’s Wish, Caring for Connor, Duchenne Now, Joining Jack, Jacobi’s Wish, Smile with Shiv and Team Felix.

What is testosterone?
Testosterone is a sex hormone in both males and females, but is particularly
important for the development of an adult male. During puberty, a boy’s
testosterone levels increase by up to 30 times as they develop into a man.
Why might testosterone be helpful to people with DMD?
The standards of care for DMD recommend treatment with glucocorticoid steroids.
Long term use of steroids almost universally causes delayed puberty by blocking the production of some hormones that regulate puberty. Treatment with testosterone can be used to induce puberty in these patients. There is some anecdotal evidence it affects penis size, is this true?
If you do not start puberty, then your penis and testicles remain the same size.
Inducing puberty increases virilisation – the development from a boy to a man – so taking testosterone will induce this.
What is the aim of the study and this extension?
The study is designed to measure the effect of testosterone treatment on pubertal development, growth, muscle strength, bone health, mood and quality of life and more. This additional funding fully support the extension study, thus helping to understand the long-term effects of puberty induction with testosterone. It will help doctors determine if ongoing testosterone replacement therapy is required and for how long testosterone should be given.
Can taking testosterone interfere with other treatments?
Without steroids, you would have normal pubertal development. There is no reason to exclude testosterone. If you are planning to be enrolled in a specific trial, you must check if taking testosterone is part of the exclusion criteria.
