What is the role of generics in the

treatment of viral hepatitis and other

dieases?

The UK National Health Service is

refusing patients treatment, because

of high prices

PrEP – TDF/FTC £4800 per year

HCV DAAs £30,000 to £100,000 per cure

Cancer Drugs Fund Shut down – prices too high

Target versus Global lowest prices:

HIV, TB and Hepatitis

Mass produced HCV DAAs should fall

to <$90 per 12-week course

The new “$90 $90 $90” in 2017

There should be standard prices to treat HIV, Hep B/C and TB

< $90 per year to treat HIV: TDF/3TC/EFV

< $90 per year to treat Hepatitis B: TDF/3TC or ETV

< $90 for first-line treatment for TB

< $90 for 12-weeks course of HCV DAAs: SOF/DCV

TDF/3TC, efavirenz, entecavir and most TB drugs will be generic worldwide in 2017. Prices should then fall in all countries, close to Indian / South African levels.

<$90 price to cure Hepatitis C will only be in low and middle income countries

Widespread access to generics

When patents have expired, drugs should be available worldwide, at close to the cost of production

However, few national health services know these costs

There is widespread over-charging. Pricing transparency is needed (WHO panel)

Lower costs for generics could drive down patented drug prices in the same therapeutic area

The Australian “All you can Treat”

contract for Hepatitis C

Contract for $1 billion Australian dollars, over 5 years, with a group of pharmaceutical companies.

For €138 million/ year, unlimited treatment numbers

In 2016, 40,000 people will be treated (20% of epidemic)

Unit cost per DAA treatment = €3,450 / person

If this price is acceptable in Australia, we should have access to DAAs at the same prices in Europe, to acheiveelimination of Hepatitis C across our region.

Options if drugs still patented -

Voluntary licenses

Some pharmaceutical companies allow cheap generics to be sold in certain low and middle income countries, with voluntary licenses. However:

1. China, South America, Russia and Eastern European countries are not included in most of these agreements. As a result, prices in these countries can be unaffordable

2. Other countries may have voluntary licenses but if the company does not register the drug for regulatory approval, then the drug cannot be accessed

3. Merck and AbbVie have no voluntary licenses for their Hepatitis C treatments.

Sofosbuvir voluntary license coverage

A new option for access to treatment:

HIV and Hepatitis C buyers clubs

There are many companies willing to export generic PrEPand DAAs into Europe and North America

Several generic ARVs are already approved by the US Food and Drug Administration and the World Health Organization.

Generic PrEP or DAAs can be bought online in 10 minutes. Prices are falling rapidly.

Conclusions - 1

In the next few months, we should see dramatic reductions in

HIV drug prices across Europe: ABC/3TC, TDF/3TC at least

90% cheaper. Fully generic combination treatments.

Generic TDF/FTC already costs only €500/year in UK – prices

should fall further. Eventually, under €90 per year.

People should be switched onto lower cost generic ARVs in

countries, where price of treatment is an issue.

Prices of branded ARVs should then be re-negotiated – their

high prices may no longer be justified.

Conclusions - 2

Elimination of disease is only affordable if drugs can be accessed at low prices, within national health budgets

We need new approaches to funding mass treatment programmes for Hepatitis C in Europe:

“All you can Treat” pricing – unlimited treatments for a fixed price

Or

Lower fixed prices. Under €4000 per cure for Hepatitis C.

Most drugs are fundamentally cheap to produce, so pharmaceutical companies can still make large profits from selling to larger numbers of people at lower unit prices.

Conclusions - 3

If pharmaceutical companies refuse to lower prices, we

need back-up mechanisms to ensure access:

• Compulsory licenses

• Buyers Clubs

• Windfall taxes on tax avoidance

Recovery of Gilead’s $10 billion in avoided tax alone would

provide sufficient funds to treat everyone with Hepatitis C

worldwide, at cost price.

Universal access to HIV treatment is one of the greatest success stories in medicine (>18 million treated).

This should not stand alone, but be repeated for mass treatment of cancer, viral hepatitis and other diseases– this time, more quickly 50
