Commencing the trial I was aware that the nature of the trial was genetic. I can’t recall, actually, if we were told if there might be side effects, but I remember the doctor being very reassuring that it was safe, and I wouldn’t have done it if I’d have thought it was unsafe.
Funnily enough, shortly after commencing the trial there was a lot of information in the newspapers to do with these kind of trials, and it was said that mouse DNA was being used to engineer, or re-engineer the DNA of some people that had certain conditions. So I was quite alarmed by this because I immediately thought, well, there must be a risk to your blood. And I was worried about leukaemia, actually – and I voiced my concern to the doctor and he reassured me that it was safe.
Obviously, I wouldn’t know, and I probably wouldn’t know now if there were any side effects. I don’t know. But I continued with the trial because I thought, “Well, I’m in it. I’m in it now so I might as well see it through.” So I did. But as I say, I was slightly concerned about the negative reports in the press about DNA-type clinical trials. I haven’t done one since, and certainly the unfortunate episode at - was it Northwick Park* - has probably put a lot of people off clinical trials. I would be very surprised if anything like that happened again, but I’ve not been tempted to do a clinical trial since, I must say.
And when all the stuff broke in the papers about concerns about using mouse DNA, you stuck with it. Did you think for a bit about giving up?
Well, I’d already had at least one injection, possibly two, so I thought [laughs], “Well, if there’s going to be any damage it’s already done”, so I thought I might as well stick it, you know, see it through, yeah. But I was concerned, I must say.
If I’d seen some of the newspaper reports prior to commencing the trial, yeah, I would have definitely had second thoughts. But as the reports only started to appear once I was a third or half-way through the trial, that’s why I thought, “Well, I might as well see it out.” But I would definitely have had second thoughts.
And do you think they should have said more, then, in the information?
Ah, possibly, yes, possibly. I mean if they genuinely believed that there couldn’t be negative side effects in any event, then okay, fair enough. But that’s not what the newspaper reports were saying. The newspaper reports were definitely putting around scare stories about it messing around with nature, you know.
Can you remember what they said about possible side effects or risks? They must have said something about it.
Well, I mean, I think they were of the nature of if it’s affecting your DNA then it could put everything into imbalance or, or - I don’t know. I’m not a scientist.
*FOOTNOTE: David is referring to a Phase 1 trial at a commercial research unit based at Northwick Park Hospital in 2006 when 6 healthy volunteers became extremely ill. ‘First-time-in-humans’ studies are carried out precisely because we need to find out about possible risks and side effects before giving the treatment more widely. Most of the people we talked to took part in trials of treatments which had already been tested in humans before.
