Reconditioning Avastin

Avastin 25mg/mL 16mL : 278€

DMLA : 0.5mg per injection

Risk of infection
 High risk injection to begin with
 Reconditioning increases the risk of introducing germs
 The reconditioning was done by hospitals, pharmacies, or the
practitioners themselves
 In August 2011, the FDA sends out an alert after clusters of Streptococcus
endophthalmitis infections.
 All were linking to the same pharmacy.

The legal frame being progressively built around this practice could improve
the quality and safety of the preparations
+
22
Reconditioning Avastin
Serious adverse events
Is intravitreal Avastin causing more cardiovascular side effects than Lucentis?

Some meta-studies have suggested that intravitreal Avastin may cause
more arterial thrombotic events.

CATT, IVAN and GEFAL :


Did not show any significant difference in side effects between the
treatments

However, none of these studies had the statistical power to detect rare
side effects

These were randomized clinical trials in a controlled environment
Is there a socio-economical effect?

No socialized medicine = disparities in patients
The patients being given Avastin are not from the same socioeconomic
background as the ones receiving Lucentis.
+
23
Is Lucentis overpriced?

Price of a drug ≠ cost of production.

The price rewards innovative research by being set based on the benefit
brought to patients and society.

Was giving such a high price to Lucentis a mistake? Was the size of the target
population underestimated?

The controversy over Lucentis and Avastin illustrates the collision of two
divergent philosophies :

Industrials and governments basing prices on cost/benefit studies

Practitioners and patients who see the possibility of just dividing
Avastin in several injections to be able to afford it
+
Off-Label Use
+
25
Off-label Use Background

The marketing authorisation holder has not investigated and tested all
potential applications of the product concerned

The producer of a medicinal product has investigated and tested a certain
application of the product, but nonetheless decides against registering it.

Off-label use may be induced by the government
+
26
Off-label Use European legislation :
definition

Guideline on good pharmacovigilance practices, Annex I : off-label use

Situations where a medicinal product is intentionally used for a medical
purpose not in accordance with the authorised product information.
+
27
Off-label Use European legislation
Pharmaceutical industry liability

Did they knew or should have known of the off-label use?

How?

Is publicly known (ex : congress)

Takes place on a large scale

Is extensively documented

Accounts for a significant percentage of the medicinal product’s sales

Was reasonably foreseeable
+
28
Off-label Use European legislation
Pharmaceutical industry liability

Impact of the pharmacovigilance directive 2010/84/CE and regulation
No 1235/2010

Adverse reaction :


« Ensure that it covers noxious and unintended effects resulting not only
from the authorised use of a medicinal product at normal doses, but
also from medication errors and uses outside the terms of the marketing
authorisation, including the misuse and abuse of the medicinal
product »
Reporting of any use of the medicinal product which is outside the terms
of the marketing authorisation

Member States have to put in place a pharmacovigilance system

Eudravigilance database (centralised medicines)

29
Off-label Use European legislation
Pharmaceutical industry liability

Warn about the risks of off-label use

Through SmPC and/or package leaflet

Risk Management plan : post autorisation off-label use (SV.4)


Off-label Use European legislation
Ex : Roche liability for Avastin
+ Off-label Use European legislation
Physicians and pharmacists liabilities


Physicians liability

Enhanced (article 5, 2001/83/EC)

Off-label prescribing should better serve the patient’s needs than “onlabel” prescription of an alternative medicine.

Off-label prescribing should have a solid scientific basis.

The prescribing physician should obtain the patient’s explicit consent to
off-label use (informed consent requirement).

The prescribing physician should keep clear, accurate and legible
records of all medicines prescribed, the reasons for prescribing them and
their (side) effects.
Pharmacists liability

Practical application is complicated, a pharmacist often being unaware
that a medicine was prescribed off-label

Off-label Use European Position for
Avastin/Lucentis
Clinical trials sponsored by healthcare bodies
comparing approved medicines with off-label
medicines was being held in 5 European countries :
The cheaper off-label medicine against the approved
treatment
NICE has included off-label
recommendations
Several sickness funds have entered into
agreements with doctors’ associations
which provide financial incentives to use
off-label medicines
LFSS 2013 and economic RTU
+
34
Off-label Use European Position for
Avastin/Lucentis
EFPIA position paper : Promotion of off-label use of medicines by European
healthcare bodies in indications where authorised medicines are available
November 2011

Decisions on off-label medicine use should remain in the hands of the treating
physician and be taken on the basis of the medical need of the individual
patient
 Medicines may not be promoted for unlicensed uses (Art. 87 of Directive
2001/83/EC).
 Priority to be given to protection of public health over economic
considerations

Promotion of off-label use by healthcare bodies may compromise patient
safety and creates legal uncertainty with regard to product liability

Promotion of off-label use by healthcare bodies sets double standards
+
35
Off-label Use European Position for
Avastin/Lucentis
Decision of the European Court of Justice (Fourth Chamber)
11 April 2013
Activities such as those at issue in the main proceedings, provided that they do not result in a modification of the
medicinal product concerned and are carried out solely on the basis of individual prescriptions calling for processes of
such a kind – a matter which falls to be determined by the referring court –, do not require a marketing authorisation
under Article 3(1) of Regulation (EC) No 726/2004 of the European Parliament and of the Council of 31 March 2004
laying down Community procedures for the authorisation and supervision of medicinal products for human and
veterinary use and establishing a European Medicines Agency, but remain, in any event, subject to Directive
2001/83/EC of the European Parliament and of the Council of 6 November 2001 on the Community code relating to
medicinal products for human use, as amended by Directive 2010/84/EU of the European Parliament and of the Council
of 15 December 2010.
Do not result in a modification of the medicinal product concerned and are carried out
solely on the basis of individual prescriptions calling for processes of such a kind do not
require a marketing authorisation

38
Off-label Use American Position for
Avastin/Lucentis

Medicare and Medicaid take charge of both medicines, Avastin and
Lucentis for AMD

Speeding-up the procedure of authorization of new applications:

Largely in response to pressures from patient groups eager to have
potentially life-saving drugs available as quickly as possible, FDA has
instituted “accelerated approval,”

Major limitation: agency cannot act on drugs for which supplemental
applications are not submitted!


Eylea It is very expensive. A typical fill can cost $1,972 or more for 1 kit of
2mg/0.05ml Eylea.

Eylea demonstrating efficacy on a par with Lucentis, but needing to be
dosed less frequently (half as often; on paper at least)

Eylea has not only assumed market share at the expense of Lucentis, but also
off-label Avastin, which is available at a significantly cheaper cost of around
$50 per injection (some 37-times cheaper than Eylea)

Eylea & Lucentis : The manufacturer has agreed a patient access scheme
with the Department of Health which involves a confidential discount applied
to the list price of aflibercept solution for injection. The level of the discount
is commercial in confidence.

Conclusion

Innovation is still in march, new products with new targets are in the pipeline.
A new drug is going to be associated with Eylea. What price to give it?

Should we give priority to cost over Health?

What role for the governments in cost-effectiveness related decisions?

What role should patients have in the decisions?

This episode constitutes a precedent of off-label use of a very similar
compound for economic reasons.
