The Hepatitis C Trust has announced it is considering
seeking judicial review of NHS England's decision to impose a cap on the number
of people treated for hepatitis C in England and Wales. Meanwhile, advocates in
Australia have won a major victory in the struggle for access to hepatitis C
treatment: a federal government decision to fund treatment for everyone with
hepatitis C in Australia. Why are two high-income countries so far apart on HCV
treatment access?
Australia negotiates volume-based pricing
The
Australian government announced in December 2015 that treatment will be
available for everyone with hepatitis C in Australia, where an estimated
230,000 people have HCV. Of these 75% have already been diagnosed.
“This was
a hard fought battle – we were told we had 'rocks in our heads' if we thought
these drugs could be made available without restriction,” Helen Tyrrell of
Hepatitis Australia told a symposium on treatment access in high-income
countries at the International Liver Congress in Barcelona in April.
“The
narrative was all about price. We aimed to change the discussion to talk about
the value of the medicines and the opportunity they presented. We showed that a high proportion of people were
in the age group where the rate of progression of liver disease increased. We
wanted them to think about elimination, about paying for a cure not tablets,
and to think about volume.”
The
Australian government has negotiated a unique volume-based price agreement with
pharmaceutical companies to treat 62,000 people at a cost of AUS$1 billion over
five years – an average price per treatment of AUS$16,129 (US$11,715 / £8234)
if all 62,000 people are treated. This deal creates an incentive for Australia
to diagnose and treat as many people as possible.
Although
the details of the agreement have not been made public, there has been
speculation that the deal includes a risk-sharing arrangement. If expenditure
exceeds a certain level in any year, the cost of any extra treatment courses is
believed to fall in a stepwise fashion until drugs are being supplied at
virtually no profit to the manufacturer – or free of charge, those with insight
into the process have told aidsmap.com.
One
Australian hepatitis expert told aidsmap.com it is possible that 30,000
people will start hepatitis C treatment in 2016 alone, potentially driving the
cost per treatment below AUS$10,000.
Hepatitis C Trust considers judicial review to challenge treatment cap in England
In Europe access to hepatitis C treatment in almost all countries is rationed
on the basis of liver disease stage, and as Professor Antonio Craxi of the
University of Palermo pointed out at the International Liver Congress, one of
Europe’s wealthiest countries – the United Kingdom – has taken one of the most
extreme positions on rationing, restricting access to 20,000 people in England
over the next two years, at an average cost of around £20,000 per treatment. In
comparison Italy treated 42,000 people from December 2014 to April 2016, but
still needs to treat three times as many people to cure those in greatest need
of treatment, Professor Craxi said.
In the United Kingdom the Hepatitis C Trust is threatening to ask the High
Court to rule on whether the Department of Health has acted lawfully in
restricting access to hepatitis C drugs that have already been approved by the
National Institute for Health and Care Excellence (NICE) – a judicial review. Medicines
approved by the NICE technology appraisal procedure should be provided by the
National Health Service in England and Wales (Scotland runs its own health
system and has already committed to providing hepatitis C drugs). NICE made a
series of recommendations by drug, genotype and liver disease stage, including
a recommendation that ledipasvir/sofosbuvir (Harvoni) should be made
available to all previously untreated people with genotype 1 infection.
NHS
England says that the limit on numbers treated is not just driven by cost,
but also reflects the logistic problems in delivering treatment to a large
number of people through specialist centres. The Australian government refused
to let concerns about capacity stand in the way of treating as many people as
quickly as possible; all general practitioners are able to prescribe
direct-acting antiviral treatment in Australia in consultation with a liver
specialist, in order to ensure equity of access.
Australia treats as many people in 1 month as England is permitted to treat in 3 months
Figures
provided by NHS England show that the entire system of 22 'operational delivery networks' in England will be permitted to treat fewer
people in a three-month period than Australian GPs started on treatment in
two weeks in March 2016. In March 2016, at least 1811 people
began treatment for hepatitis C in Australia, compared to 2790 in the whole of
2014, according to figures released by the Kirby Institute. NHS England plans to provide treatment for 2000 people with hepatitis C
from April to June 2016, with slight increases in subsequent quarters.
Approximately 160,000 people in England are estimated to have hepatitis C.
In comparison the Scottish government plans to treat 1500 people each year
up to 2020, out of an estimated infected population of 37,000.
NHS England says that the majority of 5000 people with hepatitis C and
cirrhosis have now been cured, and that NICE recognised in its guidance that
treatment for all would take several years. However, as Professor
Antonio Craxi observed at the International Liver Congress, the progression of
fibrosis is unpredictable. Clinicians are being forced to make individual
decisions about which people to treat first, leading to disappointment and
frustration for many.
“People have been waiting years for these drugs because they felt what was
on offer before was too toxic,” said Samantha May, the Hepatitis C Trust’s
Support Services Manager, in a press statement on the decision to seek judicial
review. “Now suddenly to be told they may have to wait months, even years more
is really distressing. Our helpline is overwhelmed with people who cannot
understand why NICE says they can be treated now but their hospitals are
sending them away and telling them they’ll get a letter at some point in the
future.”
The list price of the 8-week course of treatment with Harvoni
approved by NICE for people with genotype 1 is £25,986.66, almost three times
higher than the potential volume-based treatment price negotiated in Australia,
a country with almost 30% higher GDP per capita than the United Kingdom. (Drug
prices are negotiated country-by-country with reference to GDP per capita.)
What discounts NHS England may have negotiated on listed drug prices have
not been made public, but the £200 million annual envelope for hepatitis C
treatment funding implies that if treatment is rationed to 10,000 people each
year, the average price of treatment in England is around £20,000 per treatment
course.
Lack of ambition limits access
Lack of ambition in tackling hepatitis C translates directly into higher
drug costs, the contrasting Australian and British experiences suggest. Whereas
the Australian government is committed to elimination of hepatitis C as a
public health problem, the United Kingdom approach is restricted to limiting
future medical costs, with little potential impact on future transmission. Modelling
by Public Health England and academic groups suggests that targeting
treatment to 3,500 people with cirrhosis a year will be sufficient to almost halve
the incidence of end-stage liver disease and liver cancer by 2020, but to
reduce HCV incidence it will be necessary to treat people who inject drugs with
mild fibrosis, as well as people with cirrhosis.
What might be achieved in the United Kingdom – both England and Scotland –
by a more ambitious approach to hepatitis C elimination and volume-based
pricing agreements – is uncertain, but Australia's example shows that setting
an ambitious target and using government's monopoly power as the only buyer of
medicines can have dramatic effects on access to treatment.
