En el Reino Unido, el ensayo del bloqueador de la pubertad comenzará a reclutar niños desde los 11 años

A controversial clinical trial examining the effects of puberty-blocking drugs on children as young as 11 years old is set to begin recruiting participants in the United Kingdom starting August 1st. The trial, known as “Pathways,” is being conducted by King’s College London (KCL) and aims to assess the potential benefits and risks of these medications for children identified as transgender. The trial will involve approximately 226 children aged between 11 and 16. The Pathways trial had initially been scheduled to launch earlier in 2024 but faced delays due to legal challenges. These challenges were raised by Bayswater Support Group, an organization representing parents concerned about the use of puberty blockers in minors. However, the High Court recently dismissed the legal action after Mr Justice Chamberlain ruled that the trial could proceed under specific conditions. According to the court's decision, children participating in the trial would undergo extensive assessments by physicians who would determine whether the child has a reasonable chance of benefiting directly from the treatment. Bayswater Support Group expressed disappointment over the court’s ruling, stating that the trial does not meet the necessary legal and ethical standards for research involving children. The group emphasized that existing regulations require trials on minors to provide a clear prospect of direct benefit and to be based on sound scientific evidence. It argued that the trial does not fulfill these criteria and instead allows for experimental treatments on vulnerable children solely to investigate possible benefits. Kiera Bell, a former patient at the Tavistock Centre who received puberty-blocking drugs as a child and later expressed regret over her experience, criticized the court’s decision. She described the approval of the trial as a tragedy and warned against the potential harm such interventions can cause. Bell stated that the trial reflects a broader issue within the medical community, suggesting that the pursuit of such research may conflict with ethical considerations surrounding the protection of children. A representative from King’s College London affirmed that the safety and well-being of the children involved in the trial would be their top priority. The institution emphasized its commitment to conducting thorough research while ensuring the health and welfare of all participants. Dr. Hilary Cass, a paediatrician whose 2024 review questioned the basis for using puberty blockers in children, acknowledged the need for further studies despite concerns about potential long-term effects. She noted that while the NHS should generally avoid prescribing such treatments, exceptions might be made for clinical trials aimed at understanding their impact better. This perspective underscores the ongoing debate around the appropriate use of puberty-blocking drugs in minors. As the trial prepares to commence, stakeholders continue to voice their opinions, highlighting both the necessity of research into gender-affirming care and the importance of safeguarding children from potentially harmful interventions. The outcome of the trial may influence future policies and practices related to the administration of puberty-blocking medications to young individuals.
