Hello. I am David Kerr, professor of cancer medicine from the University of Oxford, England. I want to talk about an interesting paper I picked up recently in Annals of Oncology. This was prepared and presented by Dr Aggarwal from Richard Sullivan’s group at Kings College London. They have done a lot of work mapping out the health economic benefits, or otherwise, of modern anti-cancer treatments. In this review, they look at the benefits and cost-effectiveness of the Cancer Drugs Fund (CDF).
The CDF was a construct in our National Health Service in the United Kingdom that was established in 2010. The initial ideas around the CDF were noble and well intentioned; the fund was meant to serve rare conditions with orphan drugs. Those drugs, which, because of the rarity of the condition, may be approved on the basis of a phase 2 trial—single arm or randomized—without the compelling large phase 3 clinical evidence that you get from longer studies of breast or bone cancer, or some of the other common tumor types. I believe that this is a good thing. The CDF was set up after potent lobbying from some of the rare cancer interest groups. Once the CDF became political reality, however, it fell into the hands of the bureaucrats, and therefore there was a lot of game-playing by most of the oncologists in the United Kingdom.
Over a period of about 5 to 6 years, £1.3 billion was spent, predominantly for bevacizumab, cetuximab, lapatinib, and everolimus; they were the drugs most commonly used [and paid for through this fund]. These drugs were registered for almost 18 separate indications. At the end of these 6 years of funding, parliamentary review suggested that there had been very little overall survival benefit accrued by the population of UK cancer patients who had been served by the CDF.
The authors of this recent study looked very carefully at the potential benefits of the drugs that were accessed through the CDF. They compared them using the European Society for Medical Oncology (ESMO) Magnitude of Clinical Benefit Scale to assess cost-effectiveness. They applied some of the measures that the National Institute for Health and Care Excellence uses. In every situation, they concluded that the use, the creation of this “ring-fenced” CDF, added very little benefit in terms of survival to the population of patients served.
This is an interesting and important, well-conducted study. It will be somewhat controversial, at a time when an equity of access to cancer drugs is a topic of increasing debate. No doubt we need better models to work out how we physicians, peers, patients, providers, and the pharmaceutical industry can work together to come up with better, probably risk-shared models of how we access cancer drugs. Certainly in this respect, the CDF is a failure, primarily because it was misinterpreted once it was established, and because of game-playing. Many of my colleagues used the CDF to access very marginally beneficial drugs that were very expensive. It is an old, old story—expensive cancer drugs, marginal benefits. Very difficult to show any population gains in that setting. A salutary tale.
I would be quite interested for you to look over the paper and make any comments you may wish to on this video. Remember, we need to find a better way of bringing the different overlapping groups together who want to improve access to modern anti-cancer medicines.
For the time being, thanks very much for listening. I am over and out.
