Active ingredient: Oclacitinib Maleate
Product:Apoquel chewable tablets for dogs

Presentation
Apoquel chewable tablets contain 3.6, 5.4 or 16 mg oclacitinib (as oclacitinib maleate) and pork liver powder as flavouring. Light to dark brown pentagon shaped mottled tablets, with score lines on both sides. The tablets are debossed with the corresponding strength ((“S S” for 3.6 mg, “M M” for 5.4 mg and “L L” for 16 mg). The tablets can be divided into equal halves.
Uses
Indicated for the treatment of pruritus associated with allergic dermatitis and the clinical manifestations of atopic dermatitis in dogs.
Dosage and administration
For oral use.
Dosage and treatment schedule
The recommended initial dose is 0.4 to 0.6 mg oclacitinib/kg bodyweight, administered orally, twice daily for up to 14 days.
For maintenance therapy, the same dose (0.4 to 0.6 mg oclacitinib/kg bodyweight) should then be administered only once a day. The requirement for long-term maintenance therapy should be based on an individual benefit-risk assessment.
Apoquel tablets are chewable, palatable and readily consumed by the majority of dogs. These tablets can be administered with or without food.
The dosing table below shows the number of tablets required. The tablets are breakable along the score line.

Contra-indications, warnings, etc
Do not use in cases of hypersensitivity to the active substance or to any of the excipients.
Do not use in dogs less than 12 months of age or less than 3 kg bodyweight.
Do not use in dogs with evidence of immune suppression, such as hyperadrenocorticism, or with evidence of progressive malignant neoplasia as the active substance has not been evaluated in these cases.
The safety of Apoquel chewable tablets has not been established during pregnancy and lactation, or in breeding male dogs, therefore its use is not recommended during pregnancy, lactation or in dogs intended for breeding.
Oclacitinib modulates the immune system and may increase susceptibility to infection and exacerbate neoplastic conditions. Dogs receiving Apoquel chewable tablets should therefore be monitored for the development of infections and neoplasia.
When treating pruritus associated with allergic dermatitis with oclacitinib, investigate and treat any underlying causes (e.g. flea allergic dermatitis, contact dermatitis, food hypersensitivity). Furthermore, in cases of allergic dermatitis and atopic dermatitis, it is recommended to investigate and treat complicating factors, such as bacterial, fungal or parasitic infections/infestations (e.g. flea and mange).
Given the potential for effects on certain clinicopathological parameters (see below) periodic monitoring with complete blood counts and serum biochemistry is recommended when dogs are on long-term treatment.
The tablets are flavoured. In order to avoid accidental ingestion, store tablets in a safe place out of reach of animals.
Very common
(>1 animal / 10 animals treated):
pyoderma, skin lump, papilloma
Common
(1 to 10 animals / 100 animals treated):
lethargy, lipoma, polydipsia, increased appetite
nausea, vomiting, diarrhoea, anorexia
histiocytoma, fungal skin infection, pododermatitis
otitis
lymphadenopathy
cystitis
aggression
Very rare
(<1 animal / 10,000 animals treated, including isolated reports):
anaemia, lymphoma, convulsion
Treatment-related clinical pathology changes were restricted to an increase in mean serum cholesterol and a decrease in mean leukocyte count, however, all mean values remained within the laboratory reference range. The decrease in mean leukocyte count observed in oclacitinib-treated dogs was not progressive, and affected all white blood cell counts (neutrophil, eosinophil and monocyte counts) except lymphocyte counts. Neither of these clinical pathology changes appeared clinically significant.
Reporting adverse events is important. It allows continuous safety monitoring of a veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to either the marketing authorisation holder or its local representative or the national competent authority via the national reporting system.
No drug interactions were observed in field studies where oclacitinib was administered concomitantly with veterinary medicinal products such as endo- and ectoparasiticides, antimicrobials and anti-inflammatories.
The impact of oclacitinib administration on vaccination with modified live vaccines, canine parvovirus (CPV), canine distemper virus (CDV) and canine parainfluenza (CPI) and inactivated rabies vaccine (RV), on 16 week old vaccine naïve puppies has been studied. An adequate immune response (serology) to CDV and CPV vaccination was achieved when puppies were administered oclacitinib at 1.8 mg/kg bodyweight twice daily for 84 days. However, the findings of this study indicated a reduction in serological response to vaccination with CPI and RV in puppies being treated with oclacitinib compared to untreated controls. The clinical relevance of these observed effects for animals vaccinated while being administered oclacitinib (in accordance with the recommended dosing regimen) is unclear.
Oclacitinib tablets were administered to healthy, one year old Beagle dogs twice daily for 6 weeks, followed by once per day for 20 weeks, at 0.6 mg/kg bw, 1.8 mg/kg bw and 3.0 mg/kg bw for a total of 26 weeks.
Clinical observations that were considered likely to be related to oclacitinib treatment included: alopecia (local), papilloma, dermatitis, erythema, abrasions and scabbing/crusts, interdigital "cysts", and oedema of the feet.
Dermatitis lesions were mostly secondary to the development of interdigital furunculosis on one or more feet during the study, with the number and frequency of observations increasing with increasing dose. Lymphadenopathy of peripheral nodes was noted in all groups, increasing in frequency with increasing dose, and was frequently associated with interdigital furunculosis.
Papilloma was considered treatment related, but not dose related.
There is no specific antidote and in case of signs of overdose the dog should be treated symptomatically.
User warnings

Further information
Oclacitinib is a Janus kinase (JAK) inhibitor. It can inhibit the function of a variety of cytokines dependent on JAK enzyme activity. For oclacitinib, the target cytokines are those that are proinflammatory or have a role in allergic responses/pruritis.
Following oral administration in dogs at a dose ranging from 0.55 to 0.9 mg oclacitinib/kg bodyweight, the observed mean Cmax was 352 ng/ml (ranging from 207 to 860 ng/ml), which occurred at approximately 1.7 hours (tmax) post dosing.
Total body oclacitinib clearance from plasma was low; 316 ml/h/kg bodyweight (5.3 ml/min/kg bodyweight), and the apparent volume of distribution at steady-state was 942 ml/kg bodyweight. Following oral administration, the half-life is 4.8 hours in plasma. Oclacitinib exhibits low protein binding.
Overall the major clearance route is metabolism, with minor contributions from renal and biliary elimination. Inhibition of canine cytochrome P450s is minimal. Therefore, the risk of metabolic drug-drug interactions due to oclacitinib inhibition is very low.
