New Oral Testosterone Drug

A group of people representing AXYS and the Klinefelter Syndrome community traveled to Washington,
DC in early January 2018 to provide public comments at an FDA hearing related to the approval of a new
oral testosterone drug called Jatenzo.

The Clarus drug company has developed this oral pill as an alternative for men that require testosterone
replacement therapy (TRT). Currently the only options for TRT involve the use of gels, patches, injections
or pellet implants. All of these options have different challenges and difficulties that can cause some
men to become frustrated and stop following their recommended replacement plan. This can lead to
multiple physical and emotional difficulties for some KS individuals. We believe an oral alternative would
be easier for many people and would help them start and continue their TRT programs.

XXY Update – Fall, 2017

PDF

In case you have not had a chance to visit the AXYS website lately, several new research papers have been added in the library that you may want to review and also share with your health care providers and others. Two of these articles involve research by Dr. Claus Gravholt and his team at the Department of Endocrinology and Internal Medicine at Aarhus University Hospital in Denmark. This multidisciplinary clinic specializes in treating XXY individuals over the age of 15 and is one of the few clinics in the world that has that distinction. They see more than 400 adult patients with KS and have published a number of excellent research papers in the past based on their experiences.

Their latest publications focus on cognitive performance and quality of life issues associated with KS adults and they bring out many important points, including:

    1. Adult issues related to neurocognitive challenges are complex, difficult and do not receive adequate research attention or effective care.
    2. There are very few places in the world that provide expert multidisciplinary treatment for XXY adults.
    3. Most KS adults have difficulty finding skilled, effective health care from health professionals that are aware of current research in KS.
