What is an Advanced Therapy Medicinal Product?

How are they regulated?

©

What is an Advance Therapy Medicinal Product?

(a) Any substance or combination of substances presented as having properties for treating or preventing disease in human beings; or

(b) Any substance or combination of substances which may be used in or administered to human beings either with a view to restoring, correcting or modifying physiological functions by exerting a pharmacological, immunological or metabolic action, or to making a medical diagnosis.

The product must meet the definition of a Medicinal Product (MP) [Directive 2001/83/EC, amended by 2004/27/EC]:

©


An ATMP is a biological medicinal product [Directive 2001/83/EC, amended by 2003/63/EC annex 1, Part I]

that can be classified as either [EC Regulation No 1934/2007]:

- Gene Therapy Medicinal Product (GTMP)

- Somatic Cell Therapy Medicinal Product (CTMP)

- Tissue Engineered Products (TEP)

(or any combination of the 3)

©


Gene Therapy Medicinal Products (GTMP)[Directive 2001/83/EC annex 1, Part IV; amended by 2009/120/EC]

GTMP means an biological medicinal product which has the following characteristics:

a) It contains an active substance which contains or consists of a recombinant nucleic acid used in, or administered to human beings, with a view to regulating, repairing, replacing, adding or deleting a genetic sequence;

b) Its therapeutic, prophylactic or diagnostic effect relates directly to the recombinant nucleic acid sequence it contains, or to the product of genetic expression of this sequence.

GTMP shall not include vaccines against infectious diseases.

Examples of GTMPs

Recombinant viruses:AdenovirusAdeno-associated virusLentivirusPox virusMeasles virus

Plasmid DNA

Recombinant bacteria:Salmonella

Used to deliver ‘therapeutic Used to deliver ‘therapeutic genes’:genes’:

Immune modulatory genes (GM-CSF)Human cytokine receptor common gamma chain (X-SCID)β- globin gene (Thalassemia)Enzymes (pro-drug therapies)

©

Somatic Cell Therapy Medicinal Products (CTMP)[Directive 2001/83/EC annex 1, Part IV; amended by 2009/120/EC]

Somatic cell therapy medicinal product means a biological medicinal product which has the following characteristics:

a) contains or consists of cells or tissues that have been subject to substantial manipulation so that biological characteristics, physiological functions or structural properties relevant for the intended clinical use have been altered, or of cells or tissues that are not intended to be used for the same essential function(s) in the recipient and the donor;

b) Is presented as having properties for, or is used in or administered to human beings, with a view to treating, preventing or diagnosing a disease through the pharmacological, immunological or metabolic action of its cells or tissues.

For the purposes of point (a), the manipulations listed in Annex I to regulation (EC) No 1394/2007, in particular, shall not be considered as substantial manipulations.

Examples of CTMPs

Limbal stem cells (repair of chemical burns to the eye)Endothelial progenitor cells / cardiac stem cells (heart failure)Mesenchymal stem cells (anal fistula)

Genetically modified cells i.e.Haematopoetic stem cells (Host v’s graft disease; X-SCID)

©


Tissue Engineered Product (TEP)[EC Regulation No 1934/2007]

Tissue engineered product means a product that:

• contains or consists of engineered cells or tissues, and

• is presented as having properties for, or is used in or administered to human beings with a view to regenerating, repairing or replacing a human tissue.

A TEP may contain:

• cells or tissues of human or animal origin, or both• the cells or tissues may be viable or non-viable• additional substances i.e. scaffolds or matrices

A definition of what is meant by ‘engineered’ is also given

©


Examples of TEPs

Skin repair for burns or chronic wounds (in-vitro culture skin – multiple cell layers)

Trachea repair

Cartilage repair (autologous chondrocytes)

How are ATMP’s regulated?

Licensed Medicinal Products

• National- each EU member state

• Mutual Recognition/Decentralised Procedure- after national license this enables the companies to license the same

product in other member states

• Centralised- pan-EU license

All ATMP’s manufactured on a routine basis require a Centralised authorisation

[Notice to Applicants Vol 2A, Chapter 4http://ec.europa.eu/enterprise/pharmaceuticals/eudralex/vol-2/]

©


The ‘licensed’ ATMP is regulated as other biological MP except:

• the follow-up of efficacy of ATMPs and of adverse reactions are required;

• traceability requirement for MAH; data is to be kept for 30 years minimum after expiry date; in the event of bankruptcy that data will be held by EMEA.

• traceability requirement for the hospital, institution or private practice where the product is used.

• new EMEA committee for assessment: Committee on Advanced Therapy (CAT)

©

ATMP Summary

• Must meet definition of a ‘Medicinal Product’

• Are biological products that can be classified further as:- Gene Therapy Medicinal Products- Cell Therapy Medicinal Products- Tissue Engineered Products

• Licensed via the ‘Centralised’ procedure

• Licensing requirements essentially the same as all biological medicines except:- Market authorisation is reviewed by new committee (CAT)- Pharmacovigilence requires efficacy follow-up- Traceability onus on manufacturere and site where product is

administered


©

Unlicensed Advanced Therapy Medicinal Products

©


2 mechanisms to enable the use of unlicensed ATMPs:

• Specials (Directive 2001/83/EC – article 5(1))

• Hospital exemption (Regulation No. 1394/2007)

Both are regulated at a National level (by MHRA in the UK)

©


Specials

• Supplied to fulfil a special need test i.e. no equivalent licensed medicinal product available.

• Products are manufactured/prescribed by doctor, dentist or other supplementary prescriber. The administration and specification of the product is the prescribers responsibility.

• No stipulation on where i.e. hospital/private clinic, the products can be administered.

• Specials can be imported into, and manufactured in, the UK; they can also be imported out of the UK

©

Hospital Exemption

• Can only be commissioned by a medical practitioner.

• Must be custom made to meet an individual prescription and preparation must be on a “non- routine basis”.

• Must be used in a hospital.

• Must be prepared and used in the same member state i.e. no import/export permitted.


©

How are ‘Specials’ regulated?

• UK manufacturer most hold a ‘specials licence’ (an ‘MS’)- Site will be GMP inspected- Product released by ‘quality controller’, no QP requirement- Pharmacies can be the holder of these licenses

• If the ‘special’ is imported into the UK from within EU, Norway, Iceland or Lichtenstein, the importer will need:- A Wholesale Dealers License

• If imported from outside the EEA i.e. USA, the importer will need:- A Specials License

• Specification of the product and its safety is the responsibility of the prescriber if imported into the UK

• ATMPs that are categorised as ‘specials’ have to meet the requirements described in the ATMP regulation in relation to GMP, PV and traceability.


©

How are ‘specials’ regulated?

• The license holder i.e. the importer, must notify the MHRA of importation with at least 28 days notice. Information required:- Name/trade name- Active substance- Amount to be imported (limited to ≤ 25 single administrations)- Name and address of manufacturer- Evidence of compliance with EU NfG on minimising the risk of

transmitting animal spongiform encephalopathies- Evidence of compliance with ‘Tissues and Cells Directive’

• Supplier of the special is obligated to - Report and record ADRs- Maintain records relating to source of product, batches, sales

• Those administering the product are obligated to report ADRs using the yellow card scheme

Unlicenced Advanced Therapy Medicinal Products

©

How is the Hospital Exemptions regulated?

• MHRA will inspect manufacturer’s for GMP compliance- Issue manufacturer’s licence- Authorise the manufacture of categories of ATMPs rather than specific

products- Inspections will be risk based

• Manufacturer’s are obligated to:- Record and report ADRs- Risk Management Plan may be needed (case by case assessment)- Implement traceability, quality, PV standards that are equivalent to that

of a licensed product.- Provide annual returns to MHRA re frequency of manufacture/units

sold/description of product


©

How is the Hospital Exemption regulated?

• Clinician responsible for administration must record and notify MHRA of ADRs.

• Hospital where it is used must implement traceability system i.e. tracing recipient of ATMP to donors of tissues using their manufacture if applicable)

• Arrangements must be made between hospital and manufacturer for provision of data traceability in case of bankruptcy

• ATMP can be distributed from site of manufacture to hospital under the manufacturing license; but if the hospital intends to distribute it to another hospital it will need a wholesale dealers license

• Import/export of ATMPs under HE is not permitted


©


What is ‘non-routine use’?

• No definition given in the regulation (1394/2007)

• Clearly difficult to define, given:- lack of experience of regulating unlicensed ATMPs- unknown numbers and frequency of use of HE

• UK has drafted some guidance on the approach intended to be taken:- each product manufactured at the same site will be

assessed individually- the overall numbers of the product prepared, the

regularity/frequency of production, and the time period over which its manufacture has become established, will be considered

Human Tissue Authority

Health and Safety Executive

DEFRA

GTAC

• Responsibility for regulating human tissues and cells (other than gametes and embryos) for human application (EU Tissue & Cells Directive 2004/23/EC as amended):- procurement - testing - processing - storage- distribution - import / export

• The Human Fertilisation and Embryology Authority (HFEA) is responsible for the regulation of gametes and embryos for human application.

HSE / DEFRA

• ATMPs could consist of genetically modified organisms (GMO) - recombinant viruses and bacterial expressing heterologous

genes

• Administration could fall within:

- contained use directive – regulated by HSE

- deliberate release directive – regulated by DEFRA

• In the first instance, advice should be sought from HSE to determine which directive the product falls into, and appropriate notifications required

©

GTAC

Gene Therapy Advisory Committee

• Ethical oversight of proposals to conduct clinical trials involving gene or stem cell therapies.

• To provide ethical advice on the use of unlicensed gene and stem cell derived therapies

• Advise ministers on the developments in this field

©


GTMP• Liquid formulations, stored frozen (<-80oC)

• Likely to be GMO- If used under ‘contained use’ regulations

reconstitution/dilution might be necessary using class II cabinet

• Specialised, non-Ph. Eur, product specific release tests therefore ‘in-house’ release testing by pharmacy impractical. - Release for use likely to be on basis of certificate of

analysis provided.

©

CTMP

• Liquid formulations

• Very short shelf life (<2 days)

• If long term storage is possible conditions might require liquid nitrogen

• In-house release impractical- Expect to release for use on the basis of the provided certificate of

analysis

• May also be GMO which might impact on preparation requirements

• If not a GMO, preparation for administration might require class I safety cabinet to maintain sterility

How is the Hospital Exemption Regulated?

• There are defined labelling and PIL requirements for the products (www.mhra.gov.uk/Publications/Consultations/Medicinesconsultations/Othermedinesconsultations/CON051874)

• The products can not be advertised, but the service can

• GTAC can be called upon to provide ethical advice to practitioners on the use of ATMPs


©

Assuming clinical benefit has been shown, how can the doctor continue to prescribe a product used in clinical trial?

• Additional administration of product used in a clinical trial has to be conducted as unlicensed use of a MP i.e. using the specials or hospital exemption, until the MA is granted.

• Any unused CT product is still considered an IMP, so can no legally be administered as an unlicensed medicine – new product has to be manufactured.

• All requirements previously described for unlicensed ATMPs are applicable.


©


Hospital running a clinical trial involving an ATMP

• If the product is manufactured within the hospital, the site will need a ‘Manufacturer Investigational Medicinal Products’ (MIA/IMP) license.

• If donor material is used, HTA compliance for donation, procurement and testing must be demonstrated.

• Containment issues may be needed – HSE/DEFRA.

• For GTMPs in particular, storage at -80oC is common. For CTMPs might need liquid nitrogen storage.

• Isolated storage, to ensure minimisation of cross contamination, is likely to be needed.

Hypothetical Case Example 1

1. Doctor wants to treat patient with an unlicensed cell therapy manufactured in USA

• HE not possible, must use ‘specials’ procedure• Hospital/pharmacy must hold a ‘specials licence’

(issued by MHRA) before* importation• Licence holder must notify MHRA of the intention to

import not less than 28 days prior to importation• ADR’s must be notified to the MHRA using yellow card

scheme

* If you need to apply for a license it could significantly delay the importation of the product as a GMP inspection will be needed prior to issue of the license

©

2. Doctor wants to treat patient with an unlicensed gene therapy product manufactured in USA

• HE not possible, must use ‘specials’ procedure• Hospital/pharmacy must hold a ‘specials licence’ (issued

by MHRA) before importation• Licence holder must notify MHRA of the intention to import

not less than 28 days prior to importation• ADR’s must be notified to the MHRA using yellow card

scheme• Advice from HSE/DEFRA needed as this product is likely

to be a GMO- might impact on product preparation prior to

administration- HSE/DEFRA notification requirements


©

3. Doctor wants to treat patient with an unlicensed ATMP imported from a country within the EEA

• Same points as for cases 1 & 2 except - hospital/pharmacy will need to hold a

‘Wholesale Dealers Licence’ (issued by MHRA)


©

4. Doctor wants to treat patient with an unlicensed ATMP manufactured in the hospital or at a facility within UK

• Can use either ‘specials’ or ‘hospital exemption’ depending on ‘needs test’

- specials: manufacturing facility will need ‘specials licence’

- all other requirements as per previous examples

• HE: manufacturing facility will need ‘manufacturer’s licence’

• Yearly reporting on manufacturing frequency of that product will be needed to ensure fulfilment of ‘non-routine’

• Traceability/PV requirements need to implemented
