A Pilot Multicenter Field Study of a Novel Oral Therapeutic in Dogs with Canine Atopic Dermatitis

ACI is currently enrolling cases in a nationwide clinical trial to evaluate novel therapeutic designed to inhibit inflammation in dogs with atopic dermatitis. The study is designed to assess the benefit after a course of prednisone or independently.


Trial Summary

An estimated 75 client-owned dogs will be enrolled in this study. At enrollment, dogs will be randomized 4:1 prednisone to study drug. Those dogs randomized to receive prednisone will then be randomized again at Day 14 if pruritus and skin lesions caused by atopy have improved adequately. The veterinary dermatologist, and dog owner, will be masked to treatment group assignment. Study visits are required every 2 weeks for one month, and then monthly thereafter. The study duration is 4 months; however, if the dog does not respond to prednisone treatment or experiences a flare of atopic dermatitis after enrollment, the dog may be removed from study.

Trial Funding

Dogs presenting to the participating trial site will be screened for enrollment. All study related costs, including screening, are paid by the study. Either IgE serology (through IDEXX) or intradermal skin testing will be needed if not previously performed. Although previous studies with this drug have not demonstrated significant side effects , the study will pay up to $250 for medical management of adverse effects if they are thought to be a result of the study drug. If these funds are not used in full during the course of the study, the balance will be available to study pet owners for follow-up dermatology care.

Trial Eligibility

To qualify for enrollment, dogs must meet the following criteria:

  • Client-owned dog > 1 year of age
  • Body weight ≥ 5.0 kg
  • Diagnosis of Atopic Dermatitis based on clinical signs, rule-out of resembling conditions (e.g. flea allergies, ectoparasites and bacterial or yeast skin infections). For homogeneity purposes, dogs with food-induced AD will be eliminated from inclusion.
  • Non-seasonal Atopic Dermatitis
  • More than 3 positives on allergen-specific IgE serology or intradermal testing
  • Canine Atopic Dermatitis Extent and Severity Index-4 (CADESI-4) Score of ≥ 25
  • Pruritus Score ≥ 5.5
  • Use of a veterinarian recommended flea product, in endemic areas, for a minimum of 3 months.

Dogs cannot be enrolled if there has been:

  • Use of the following medications from the time of enrollment:
    1. Injectable long-acting glucocorticoids in the past 6 weeks
    2. Oral glucocorticoids, cyclosporine, calcineurin inhibitors, long-acting injectable antimicrobial agents or agents with known anti-pruritic activity (Staphage Lysate, gabapentin, monoamine oxidase inhibitors and tacrolimus) in the past 4 weeks
    3. Topical nonsteroidal anti-inflammatory drugs and topical glucocorticoids in the past 3 weeks
    4. Anti-histamines and oclacitinib in the past two weeks
    5. Oral antibacterial or antifungal agents in the past week.
  • Use of allergen-specific immunotherapy initiated in the last year (If allergen-specific immunotherapy has been used for more than 1 year, dog is still eligible)
  • History of seasonal Atopic Dermatitis
  • Evidence of ectoparasites or bacterial or yeast infection
  • Change of food or food supplements (fatty acids, omega-3s) within the last 6 weeks
  • Dog is pregnant, likely to become pregnant or intended for breeding
  • Dog has another major medical condition requiring pharmaceutical intervention
  • Dog has a serum chemistry, hematology or UA finding that is, in the opinion of the Investigator, clinically significant and may indicate a concomitant illness.
  • Dog is participating in another study
  • Dog may not be available for the entire study duration
  • Owners unable or unwilling to assess pruritus throughout the study

Great Pyrenees with Osteosarcoma

ACI is conducting a study that collects saliva sample, buccal (cheek) swabs, and a small amount of whole blood from Great Pyrenees that are diagnosed with Osteosarcoma. Eligible dogs may be newly diagnosed, currently receiving therapy, or previously treated.

Trial Eligibility:

  • Any purebred Great Pyrenees with Osteosarcoma
  • Any age, breed, or sex is eligible

Trial Support

This study is a voluntary study for pet owners whose dogs meet the above criteria.

Saliva collection kits and buccal swabs will be provided to pet owners at no charge with sampling and mailing instructions inside. A kit with prepaid return packaging will be mailed to the owners for quick and easy return. Blood samples are requested, but not mandatory. Please contact ACI for information on how a blood samples can be obtained in your area.
