I thank the noble Baroness for her comments about the importance of evidence. The Government and the MHRA recognise some of the difficulties around these trials. That is part of the reason that NIHR is supporting two trials and is asking people to come forward. The MHRA has also indicated that it is willing to work with those who have these products in order to support them in the process for licensing.
That has reminded me of one other point. The noble Baroness, Lady Walmsley, asked me about the NHS commissioning through evaluation programme. I undertake to write to her with a response, perhaps when I update the noble Baroness, Lady Thornton, on prescription numbers.
