Brief Summary

Gender dysphoria (GD) is a significant suffering lasting more than 6 months in a subject, with regard to the discrepancy felt between his or her gender identity and his or her birth sex. From the onset of puberty, most of these self-identified transgender adolescents will persist in their transgender identity and will undergo hormonal and surgical reassignment when the time comes. International best practice guidelines recommend early treatment from the start of pubertal development to block pubertal progression, with the possibility of hormonal transition by administering sex hormones of the desired sex usually around the age of 16. However, in order to reduce the psychosocial consequences of GD, more and more referral teams are carrying out this transition from the age of 14, although no study has been published to show its benefit compared with a transition at the age of 16. In the absence of treatment, co-morbidity among adolescents suffering from gender dysphoria is very high, with anxiety-depressive states, suicidal risk and dropping out of school in the forefront. Our hypothesis is that hormonal transition started at an age closer to physiological puberty can significantly reduce this comorbidity and improve quality of life for these adolescents. This is the first therapeutic trial to be conducted in France in the transgender adolescent population, in an area where international recommendations based on the principles of Evidence Based Medicine are essentially derived from the clinical expertise of teams who have specialized in the care of transgender people for over forty years, while clinical data derived from structured research are still very scarce. The results of this study will guide the care of transgender adolescents, allowing them, if the study is positive, to access hormonal treatments earlier and thus more quickly improve their overall functioning, anxiety-depressive symptoms and their quality of life.

Outcome Measures

Primary Outcomes (1)

  • Global functionning using the Children's Global Assessment Scale (CGAS)

    The Children's Global Assessment Scale (CGAS), adapted from the Global Assessment Scale for adults, is a rating of general functioning for children and young people until 16 years old. The clinician assesses a range of aspects of psychological and social functioning and gives the child or young person a single score between 1 and 100, based on their lowest level of functioning. The score puts them in one of ten categories that range from "needs constant supervision" (1-10) to "superior functioning" (91-100). The measure can be used by clinicians as well as researchers to complement other scales measuring more specific symptoms.

    16 years old +/- 6 months

Secondary Outcomes (16)

Masking Details
The assessment of the primary criteria will be carried out by a psychologist who will have no knowledge of the teenager's allocation group and will not have been involved in his or her care. At T1, the assessment will be based on key elements of the patient's file provided to him or her without any element that could indicate his or her allocation group or original gender, and a telephone interview with the teenager and his or her parents in which they will have been told in advance not to reveal the allocation group or gender. The psychologist who assesses a 16-year-old will be different from the one who assesses a 14-year-old. Psychological assessments other than the primary criterion, and the assessment by the pediatric endocrinologist, will take place at the site of the patient's usual care. Adolescents will be monitored as part of their usual care.

Intervention Model
PARALLEL
Model Details: Multicenter, controlled, randomized, open trial with blinded evaluation of the primary endpoint (Prospective Open Blinding Endpoint PROBE study). Randomization will be stratified by sex assigned at birth and the investigating center. The primary analysis will be intention-to-treat and multiple imputation methods will be used to handle missing data. After verification of the inclusion criteria by the child psychiatrist (selection visit), then the pediatric endocrinologist (inclusion visit), the adolescent will be included in the study and will benefit from an initial evaluation (T0) by a psychologist trained for the primary criterion (CGAS) and secondary psycho-affective criteria. The patients will then be sent again to the pediatric endocrinologist who will randomize the patient (via an IT platform) and give them the treatment corresponding to their assigned group.
