Degenerative mitral valve disease is the most common heart disease in dogs. In dogs that progress to congestive heart failure (CHF), cardiac cachexia (muscle loss) occurs frequently and reduces strength, immune function, and overall survival. Having a medication that could improve appetite, body weight, and muscle would be very beneficial for the dogs. Although a medication that improves these important issues might not alter the underlying heart disease, it could improve malnutrition and quality of life, which could have direct benefits on survival.
Capromorelin is drug that mimics the effects of a hormone called ghrelin. Ghrelin’s normal function in our body is to make us feel hungry, and also to increase lean body mass. Capromorelin was recently approved as an appetite stimulant in dogs so it has gone through extensively tested.
This study will evaluate whether capromorelin can reduce the loss of body weight, muscle, and appetite in dogs with CHF. Dogs will be randomized to receive either capromorelin or a placebo for 60 days (owners and investigators will not know which one). Dogs will be evaluated at baseline (Day 0), and on Days 30 and 60, for a total of 3 visits. Evaluation will include assessment muscle mass (by ultrasound), body weight, muscle condition score, body condition score, quality of life, appetite, 6-minute walk test, blood tests, and echocardiography (ultrasound of the heart).
The study will cover all of the costs associated with the planned measurements for the 3 study visits, including the cost of the capromorelin or placebo. If additional tests are needed based on your dog’s underlying heart failure, these will not be covered by the study. In addition to the benefits to you and your dog, your dog’s participation will also allow us to gain information which will help in the treatment of other dogs with heart failure.
