I thank my hon. Friend for securing this debate. I met my constituent Jack when I went to visit our local hospital. It is not surprising that I met him, because he spends six months in the hospital every year. He is now running out of treatment; he has tried everything. He is on 30 tablets a day, and he is on nebulisers. He is trying treatment after treatment, and the treatments are running out. Patients like Jack need this drug urgently, because there is almost nothing left.
