Phase II Rapamycin Clinical Trial

***Enrollment for this study is currently suspended. Please check back later for updates on enrollment!***

Title: Phase II Rapamycin Clinical Trial
Contact Person: Jaime Brannan | rapaphase2@dogagingproject.com
Species: Dogs
Inclusion Criteria and General Background Information: 50 dogs are required to complete the study
・Dogs must be healthy and cooperative for physical exam.
・Dogs must be 6-10 years old, and 40-80 pounds in size.
・Dogs must be heartworm test negative and receiving consistent heartworm prevention.
・Medical history, physical examination and blood and urine tests will be used to determine health status.The study duration is one year, and all dogs will be enrolled in College Station, Texas. Enrolled dogs will be randomized to receive rapamycin or placebo for 6 months, and monitored for a year. Dogs will be examined 4 times over the course of the year and owners will complete health-related questionnaires at each study-related visit and periodically throughout the year.
Exclusion Criteria: More than 50 dogs will be screened for enrollment and dogs will be excluded if:
・They are not cooperative for physical or cardiac exam.
・Evidence of systemic illness is found on history, physical examination or blood and urine tests.
Owner Commitments: Owners must be able to:
・Attend 4 scheduled veterinary visits in College Station over the period of one year.
・Administer study medication (rapamycin or placebo) as directed for 6 months.

Evaluation of an oral low-dose dexamethasone suppression test using urine cortisol: creatinine ratio in dogs with suspected hyperadrenocorticism.

Title: Evaluation of an oral low-dose dexamethasone suppression test using urine cortisol: creatinine ratio in dogs with suspected hyperadrenocorticism.
Contact Persons: Please contact either Dr. Audrey Cook or Dr. Amber Graham via email or phone at 979-845-2351.
Species: Canine
Inclusion Criteria and General Background Information:
  • Client owned dogs with a high clinical suspicion for hyperadrenocorticism.
  • Patients must have a complete blood count, chemistry, urinalysis and abdominal ultrasound.
  • Diagnosis of hyperadrenocorticism can be difficult as no available diagnostic test is perfect. The low dose dexamethasone suppression test is currently the screening test of choice. However, this diagnostic test requires an intravenous injection, the collection of several blood specimens via venipuncture as well as 8 hours of hospitalization. It is known that stress can impact the results of this diagnostic test and potentially lead to misdiagnosis. The purpose of this study would be to demonstrate the efficacy of an at home oral low dose dexamethasone test in the diagnosis of canine hyperadrenocorticism as compared to the ACTH stimulation test and traditional LDDS test. As this is all done in the home, this test will be less stressful for the patient and we hypothesize the oral-LDDS test will be more specific than the traditional LDDS test and lead to more appropriate diagnosis of hyperadrenocorticism.
Exclusion Criteria:
  • Dogs who have been treated with short-acting glucocorticoid within the previous 2 days, or a long-acting glucocorticoid within the previous 3 months.
  • Dogs on other medications will be considered on a case by case basis.
Owner Commitments: The owner will be asked to collect three baseline urine samples on three mornings. Then the owner’s will be instructed to give the pet a capsule containing either dexamethasone or placebo every night at bedtime for 7 consecutive days. They will then be asked to collect a free catch urine the following morning.
Financial Incentives:
  • The owner will be responsible for initial diagnostics including CBC, chemistry, urinalysis and imaging.
  • If eligible, the cost of endocrine testing including a low dose dexamethasone test and ACTH stimulation test will be covered by the trial.
