Why the 5000% price hike for pyrimethamine in the US is relevant in the UK

The 5000% increase in price in the US for an off-patent drug by a company with a monopoly license was widely reported earlier this month. This was based on a very good article on Monday 21 September in the New York Times (NYT). [1]
The least interesting aspect of the story however, was the company responsible for increasing the price or its noxious CEO. The real story was that the US has a system that allows this to be legal – and that the US is currently driving new trade agreements (TTIP) that threaten similar restrictions globally.
The news story relateed to pyrimethamine which has been off patent for decades. This is an important drug. It is used to treat toxoplasmosis which affects people with suppressed immune systems (transplant recipients, and HIV positive people) but also women during pregnancy (irrespective of HIV and immune status) and children who are infected with toxoplasmosis at birth.
However, most of the story is about US-access and is US-based. It relates to a regulatory and licensing system that allows any single manufacturer to have a license for a drug that is already off patent. The NYT article referred to other widely used off-patent medicines that have undergone similar monopoly-based investment pricing, including the antibiotics doxycycline (multiple use, including treatment for some common STIs) and cycloserine (for drug-resistant TB). It is about a broken system that needs fixing.
The story raises issues about:
- Monopoly licenses and importance of competition for drug pricing.
- How monopoly licenses can be granted for off-patent drugs.
- Monopoly licenses to drugs on the WHO list of Essential Medicines for citizens of all countries. Pyrimethamine is listed as an essential medicine for both adults and children to treat pneumocystosis, toxoplasmosis and malaria. [2]
- Use of online pharmacies to import generic medicines for personal use. This is perfectly legal in many high income countries, including the UK, if this for personal use, irrespective of drug patent. [3]
- Lack of any regulation between drug approval and drug pricing. For any drug, in-patent or off-patent, the manufacturer can set any price that the market will pay.
For people in the US, the option to access import generic medicines for personal use should also be available. US citizens widely use Canadian and other online pharmacies, although this may complicate reimbursement costs for those on insurance-based care. But while access to online suppliers might overcome the short-term cost issue for individuals, this probably excludes health providers who will be stung by monopoly price increases. A challenge to the license should therefore be an advocacy issue strengthened by the option for public health providers to also be able to do this for their patients.
From the 1970s, the Indian generic manufacturer Cipla led generic access to medicines for 90% of the world’s population living in low and middle income countries. As with other generic companies, Cipla are a for-profit commercial company and they list pyrimethamine as one of their current products. Based on the cost of co-formulated pyrimethamine plus sulfadiazine at less than $0.45 a tablet from online suppliers, the earlier US price of $13.50 a tablet seems steep even before the hike to $750. [4, 5]
This story highlights the risk for monopoly licenses for medicines in any situation. It especially highlights the risk for medicines that are off-patent, without linking this to a requirement for pricing. The move to further strengthen and restrict global patents for medicines has been an ongoing concern for at least the last decade.
For people outside the US, this news story on pyrimethamine might appear to have little direct impact – so long as generic manufacturers continue to manufacture pyrimethamine, including as a separate drug. Most use for pyrimethamine however is in a two-drug coformulation of pyrimethamine plus sulfadiazine in a single tablet, which is still widely available from many generic manufacturers. [6]
But the continued access to generic medicines outside the US, including in the EU, is directly threatened by proposed changes to EU legislation – the Transatlantic Trade and Investment Partnership (TTIP) – that would extend and strengthen patent rights globally for all medicines. [7, 8, 9, 10]
Given that 65-85% of all prescribed medicines in the UK are generic, fighting to retain access right to medications is an issue that does and will affect us all.

Comment
On Tuesday 22nd September, Martin Shkreli, founder and head of the small opportunistic Turing Pharmaceuticals, and personally responsible for the public relations wreck that generated his widespread vilification, announced that the original price of primethamine would be restored.
However, as this issue of HTB went to press in mid October, the US price had still not been lowered.
Unless legal changes are made to the system that allows such approaches to pricing of medicines, this example highlights vulnerability to similar practice in the US in the future.
