Select Committee on Science and Technology Minutes of Evidence


Examination of Witnesses (Questions 229 - 239)

WEDNESDAY 15 JULY 1998

MR BOB YERBURY, MR NEIL WOODFORD AND MRS MARGARET RODDAN

Chairman

  229. Mr Yerbury and colleagues, thank you very much for coming along this afternoon. I take it, Mr Yerbury, that we should direct our questions to you and if you feel it appropriate to ask one of your colleagues to take the question, then you will do so, but we will direct our questions to you in the first place?

  (Mr Yerbury) Absolutely.

  230. Thank you once again for coming to be with us this afternoon. I am sure you followed our first evidence session. You know how far we have got on this particular short inquiry and I believe you were in the public gallery for the session we have just had, so you know the questions we have already asked this afternoon. In your memorandum, for which I thank you, you stated: "In February 1998, conversations with a City analyst"—and I think we probably know who that was—"heightened concerns that you had about the company's level of spending". I think you mean British Biotech—when you say the company's level of spending and its ambition to develop into a fully integrated pharmaceutical company. What was the nature of your concerns?
  (Mr Yerbury) The concern was that the company seemed to be spending money faster than would have been indicated by the level of cash on the balance sheet and our concern was that they might not have the resources to bring to fruition the product that we were particularly interested in, which was Marimastat. So the concern was that they were just spending money too fast and it would not enable them to pursue the trials to the end of their course.

  231. In quoting from your memorandum I did actually say when we referred to the City analyst that I think we had a pretty good idea who that was. I think there is little doubt from the previous evidence that that analyst was Jane Henderson?
  (Mr Yerbury) It was.

  Chairman: And I do not think there is any secret about that? Dr Jones, did you want to come in at this point?

Dr Jones

  232. Could you just tell us when Ms Henderson phoned you exactly what she said?
  (Mr Yerbury) I was not party to the telephone call.

  233. Sorry, Mr Woodford, yes?
  (Mr Woodford) I knew that Ms Henderson obviously was going to see British Biotech. We had some concerns already before that meeting and therefore we were very interested to see whether somebody coming to it afresh was going to be able to be enthused enough to want to initiate coverage, so it was quite an important meeting and that is why the phone call took place after the meeting. Obviously I was disappointed to learn that she was not going to initiate coverage and I took that and what she said about the meeting and the fact that she had decided not to initiate coverage as obviously a negative signal.

  234. So you knew that this meeting was going to take place. She phoned you, rather than you phoning her?
  (Mr Woodford) I cannot remember who phoned who actually, but we had a conversation. I ring analysts, analysts ring me all the time.

  235. You say that you had concerns before the meeting. What were those concerns?
  (Mr Woodford) They were general concerns. We were aware that the company was spending a lot of money. The rate of cash burn had increased. We were not quite fully appraised of how much that spending had increased, but what concerned us, particularly with regard to Marimastat—and that has been the focus of our concern all along—Marimastat is the anti-cancer product in trials. It is in a number of different trials. We felt from our analysis that the trials which had the greatest potential to show efficacy for the product were the trials that would take the longest to complete. The trial that was the quickest to finish was the pancreatic cancer trial. That was going to complete in the first quarter probably of next year, but it was a very high obstacle for the drug to show efficacy in, if you like; pancreatic cancer is a very vicious form of cancer as I am sure you know. The current treatment is with cytotoxic drugs. The benchmark for the action of Marimastat seemed to be very high. Basically, the action of Marimastat, as you know, is to surround tumours; the tumour in pancreatic cancer has been described to me as like a steak on a plate and therefore with a limited amount of time it was very difficult for the drug to do what it is intended to do within the life expectancy of a patient who has this disease and therefore it was a very tough trial. The concern was that if a tough trial is not going to give the result that we were hoping for, then this company has to have enough money left to see it through to the end of the trials which will complete later, maybe two or three years down the road.

  236. So you would not have been worried if the company had been spending money on buildings if you had been confident that the drugs that they were producing were going to be successful? You had doubts about the drugs too? I understand it was a long period—
  (Mr Woodford) Yes, there were certain—

  237. But there were other drugs, the other two drugs?
  (Mr Woodford) The other drugs to an extent, or the other one drug, were interesting but the focus of our attention, right from the start when we started investigating British Biotech was always the anti-cancer therapies, originally, Batimastat and subsequently Marimastat. In our opinion, the focus of the evaluation, the focus of the upside, if you like, was always in Marimastat and therefore that was the centre of our concern.

Mr Beard

  238. In what detail did you examine their business plan, the proposal to develop three drugs and commercialise them?
  (Mr Woodford) When we analysed the company obviously the most important thing was to come to an opinion about the likelihood of a particular drug showing efficacy in a particular therapeutic area and then assessing the market impact or the marketing potential, the size of the market for that drug.

  239. When you took an interest in this, what was the likelihood of the three drugs being successful from that stage of development?
  (Mr Woodford) In Phase I and Phase II, the chances of producing a viable and profitable drug are fairly low. Different analysts ascribe different probabilities to drugs in development and normally there is a step change in the probability attached to a drug going through that process. So if you are in Phase I you may have only a 10 or 15 percent probability of achieving a viable drug. If you get it into Phase II then there is a step change in the sort of evaluation model and it may go up to, say, 30 or 40, and again if you get into Phase III then the probability increases. So all the while what you are doing with a drug is looking at the therapeutic area that drug is addressing and attaching a probability to the ultimate market size.
