i)       the nervous system;

iv)     the digestive system;
v)      the urinary system;
vi)     the reproductive system;

x)      the endocrine system.


(b) Substances falling within, but not limited to, the following –
acidifying agents; adrenergic blocking agents; adrenergic stimulants;
agents affecting calcium and bone metabolism; alcohols; alkalinising agents; anabolic agents; anaesthetic agents; analgesics; antianginal agents; antianxiety agents; antiarrhythmic agents; anticholinergic agents; anticoagulants; anticonvulsants; antidepressants; antiemetics; antifibrinolytic agents; antihistamines; antihypertensive agents; anti-inflammatory agents; anti-nauseates; antineoplastic agents; antipsychotic agents; antipyretics; anti-rheumatoid agents; antispasmodic agents; antithrombotic agents; antitussive agents; blood coagulants; bronchodilators; bronchospasm relaxants; buffering agents; central nervous system stimulants; cholinergic agents; corticosteroids; depressants; diuretics; erectile dysfunction agents; fibrinolytic agents; haematopoietic agents; haemostatic agents; hormones (including trophic hormones) and their synthetic counterparts; hypnotics; hypoglycaemic agents; hyperlipidaemic agents; immunomodifiers; masking agents; muscle relaxants; narcotic analgesics; neuromuscular agents; plasma; volume expanders; respiratory stimulants; sedatives; stimulants; sympathomimetic amines; tranquillisers; vasodilators;
vasopressor agents; vitamins administered by injection; oxygen carriers;


(c)     Agents that are capable, at any time, of directly or indirectly causing an action or effect on, and/or manipulating, gene expression in any mammalian body, including but not limited to gene editing agents with the capacity to alter genome sequences and/or the transcriptional, posttranscriptional or epigenetic regulation of gene expression.

233.  Prohibition of Genetic Therapy, Gene Editing and Genome Editing where: –
(a)     Genetic Therapy is defined as including any therapy, method or process which involves the use or administration of: –
(i)      oligomers or polymers of nucleic acid
(ii)    nucleic acid analogues
(iii)    genetically modified cells


(b)     Gene editing agents which are capable, at any time, of directly or indirectly causing an action or effect on, and/or manipulating, gene expression in any mammalian body, including but not limited to gene editing agents with the capacity to alter genome sequences and/or the transcriptional, post-transcriptional or epigenetic regulation of gene expression and are prohibited.

For the avoidance of doubt, the following are not defined as a Genetic Therapy for the purpose of the IABRW: –
(i) the use or administration of autologous conditioned serum or
(ii) “platelet-rich plasma” treatments which do not involve the transfer of whole cells / DNA;

        
(c)     Exempted Genetic Therapy: –
(i)      Genetic Therapy may be used or administered to a specific horse with the express prior approval of a Racing Authority if that Genetic Therapy is used to treat an injury or disorder formally diagnosed by a veterinarian, and
(ii)    is not capable of modifying a horse’s heritable genome;
(iii)    does not pose a threat to the welfare of horse;
(iv)    does not pose a threat to the integrity of racing, either by having the potential to enhance or harm the performance of a horse in a race.


(d)     Control and recording: –
(i)      The owner or trainer has the responsibility to inform and obtain the approval of
the Stipendiary Stewards of any intended Genetic Therapy to a horse prior to such treatment, irrespective of whether it is to be administered before, in or out of training.
(ii)     The owner or trainer must maintain full and accurate records of all such therapies – which must be kept for a minimum of five years and be readily available for inspection by regulatory officials when requested.


(e)     Prohibition on Gene Editing and Genome Editing: –
(i)      Gene Editing is defined as any process or treatment in respect of a horse which
involves the insertion, deletion and/or replacement of DNA at a specific site in the genome of the horse including any process or treatment in respect of a horse which involves the insertion, deletion and/or replacement of DNA in the genome of the horse.
(ii) The use on, or administration or application to, any horse of Gene Editing or Genome Editing is prohibited at all times.

 

234.  Any medicine, drug or related substance that has been prescribed by a Veterinarian and, notwithstanding the manufacturers’ label, must also contain a further label indicating at least the following: –
(a)     the name, qualifications and address of the veterinarian by whom the medicine, drug or related substance was prescribed;
(b)     the name, qualifications and address of the veterinarian or pharmacist by whom the medicine, drug or related substance was dispensed;
(c)     the name and signature of the person or persons administering and/or authorising the treatment;
(d)     the name of the horse to which the medicine, drug or related substance is to be administered;
(e)     the dosage, route of administration, date and frequency of administration, of the medicine, drug or related substance;
(f)     the name of the person to whom the medicine, drug or related substance is dispensed;
(g)     the name of the treatment (brand name of active constituent).
These may not be actionable if a legitimate treatment is appropriately recorded within 24 hours of treatment being administered.

235.  Save for a licensed Veterinarian, any person who attempts to obtain and/or is in possession of a prohibited substance as specified in the rules or a metabolite, artifact or isomer of such substance, shall be guilty of an offence and shall be liable to any penalties provided under Rule 11(d).

Any person who contravenes any of the rules set out above shall be liable to any of the penalties provided for under Rule 11(d).

 

ILLICIT SUBSTANCES
235B. Except for a substance authorised below, no anti-bleeding substance shall be administered to a horse on a racing day.
