Imrestor 15 mg solution for injection for cattle
2.QUALITATIVE AND QUANTITATIVE COMPOSITION
Each 2.7 ml
Pegbovigrastim (Pegylated bovine Granulocyte Colony
Stimulating Factor [PEG
For the full list of excipients, see section 6.1.
Solution for injection
Clear, colourless to pale yellow solution
Cattle (dairy cows and heifers).
4.2Indications for use, specifying the target species
As an aid in a herd management programme, to reduce the risk of clinical mastitis in periparturient dairy cows and heifers during the 30 days following calving.
Do not use in case of hypersensitivity to the active substance or to any of the excipients.
4.4Special warnings for each target species
In a European field trial, the incidence of clinical mastitis observed in the treated group was 9.1 % (113/1235) and in the control group 12.4 % (152/1230), showing a relative reduction in mastitis incidence of 26.0 % (p=0.0094). The efficacy was tested together with normal management practice. Clinical mastitis is investigated as a change in the appearance of the milk or of the quarter or of both milk and quarter.
Based on all field studies, the proportion of mastitis prevented due to herd treatment with Imrestor (Prevented Fraction) is 0.25 (with 95% confidence interval 0.14 – 0.35).
The product should only be used on the basis of a positive benefit: risk assessment performed at the herd level by the responsible veterinarian.
4.5Special precautions for use
Special precautions for use in animals
Only for subcutaneous administration.
In one safety study in Jersey cows the margin of safety of this product was 1.5x the highest recommended dose (an overdose of 60µg/kg was administered on three occasions) (see also section 4.10). Do not exceed the stated dose.
As expected from the mode of action of the active substance, safety data shows that a mild and transient rise in somatic cell counts in individual cows may be seen.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
In the case of accidental
People with known hypersensitivity to pegbovigrastim should avoid contact with the veterinary medicinal product.
Personal protective equipment consisting of gloves should be worn when handling broken or damaged syringes. Remove gloves and wash hands and exposed skin after use.
4.6Adverse reactions (frequency and seriousness)
In the clinical studies,
Subcutaneous administration of the product may induce transient local swelling at the injection site as well as inflammatory reactions which resolve within 14 days post treatment.
The frequency of adverse reactions is defined using the following convention:
-very common (more than 1 in 10 animals displaying adverse reaction(s) during the course of one treatment)
-common (more than 1 but less than 10 animals in 100 animals)
-uncommon (more than 1 but less than 10 animals in 1,000 animals )
-rare (more than 1 but less than 10 animals in 10,000 animals)
-very rare (less than 1 animal in 10,000 animals, including isolated reports)
4.7Use during pregnancy, lactation or lay
Can be used during pregnancy and lactation.
4.8Interaction with other medicinal products and other forms of interaction

4.9Amounts to be administered and administration route

A single syringe delivers a dose of
Excessive shaking of the syringe may aggregate pegbovigrastim, reducing its biological activity. The solution should be visually inspected prior to use. Only clear solutions without particles should be used.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
Evidence from similar active substances in humans suggests that accidental administration of more than the authorised dose could result in adverse reactions, which are related to the activity of pegbovigrastim.
Treatment should be symptomatic. There is no known antidote.
In one safety study in Jersey cows, at overdose of 60 µg/kg, administered on three occasions (1.5x the highest recommended dose), abomasal ulcers were observed.
