My Lords, I start by thanking the noble Baroness, Lady Cass, for her work in this very important area. I also refer to the actions taken by the previous Government, which set in train the action we are continuing. As both the noble Lord, Lord Kamall, and the noble Baroness, Lady Walmsley, rightly said, this is about keeping children safe. There is nothing more important than evidence-based action—which is what we have before us—and taking the necessary steps.
The Cass review made it clear that there is not enough evidence about the long-term effects of using puberty blockers to treat gender incongruence to know whether they are, first, safe and, secondly, beneficial. It is important to bear both in mind. The Commission on Human Medicines independently found that clear evidence of unsafe prescribing exists and recommended that there should be a ban until there can be a safe prescribing environment. That is where we start, and last week’s laying of legislation stops that unsafe prescribing to children and allows time to develop the necessary safeguards, as recommended by the commission. I should just clarify that the legislation is indefinite, not permanent. There will be a full review in 2027 so this continues to be a very live issue.
The clinical trials, referred to by both the noble Lord, Lord Kamall, and the noble Baroness, Lady Walmsley, will be a world first. It is important to pay tribute to that. In addition to the work currently being undertaken to respond to the recommendations of the Commission on Human Medicines, the trial is presently undergoing development and approvals. The aim is to begin recruitment early in the new year. I am sure there will be an opportunity to update the House on that detail.
In answer to the point from the noble Baroness, Lady Walmsley, the numbers will be uncapped, which is important. I am sure we all agree that better-quality evidence is critical. The development of the clinical trial between the National Institute for Health and Care Research and NHS England will provide the better-quality evidence that we are all looking for.
