Pathways Study: Puberty Suppression

Adam Thompson Excerpts

Monday 22nd June 2026 Commons Chamber

[James Murray]

I am sure that the hon. Lady will agree that this is now one of the most heavily scrutinised clinical trials in this country in recent history, and rightly so—it is right that it is so heavily scrutinised and that we all seek assurances about the safeguards in place. It is right that, as Health Secretary, I made sure that I got those detailed safeguards before coming to the House to set out the Government’s position today.

The hon. Lady asked how usual it is for the MHRA to work with the sponsors of trials. My understanding is that the MHRA routinely works with trial sponsors to iterate the protocols in relation to those trials. Because this trial involves children and young people, for me, the bar should be exceptionally high, to ensure that those safeguards are in place. That is why, although my starting principle is that clinical evidence is the right way to approach such a matter, I wanted that extra reassurance. That is why I asked for the most detailed possible assurances from my clinical advisers, to ensure that those robust safeguards are in place in the way the trial is now designed.

Before my election, I was a scientist—albeit not in the health sciences. Using that background, however, can I agree with the Secretary of State that healthcare practices and medical trials, like all scientific trials, must be led by expertise and evidence, not politics? Therefore, what precedent is there for politicians, including Members of this House, intervening in a medical trial?

[James Murray]

My hon. Friend raises an important point about the relationship between politics and clinical evidence and clinically led decisions. Being led by clinical advice and clinical evidence is a decision that I and this Government stand behind. In this case, it is a matter where in considering some of the issues raised, I have felt uncomfortable and uneasy, but that commitment to clinical evidence, particularly recommended by someone as widely respected as Dr Cass, is the basis on which we can move forward. As I mentioned in response to the Chair of the Health and Social Care Committee, because this involves children and young people, I wanted to receive extra assurances that the clinical advice was robust and that the safeguards would be as robust as possible. That is the assurance I have received, it is what I very much wanted to receive before coming here today.
