We gained substantial and seemingly important information relative to the aims of this study. We were able to obtain the initial set of samples on April 26, 2018 so we had a short delay in starting this study. Subsequently, the COVID epidemic and loss of research personal resulted in repeated interruptions in our research efforts. After completing all Year I study aims, we continued to work on improvements in immunohistochemistry and FISH localization of Bartonella organisms within various cell types.

Research Update CHF 02534 MY 4 Update: Clinical Trial for Evaluation of Propranolol and Doxorubicin in the Treatment of Canine Hemangiosarcoma
Our overall objective is to determine a clinically optimal dose and estimate the efficacy of propranolol in dogs with hemangiosarcoma when given as an adjunct to chemotherapy. Specifically: Continue reading “Research Update CHF 02534 MY 4 Update: Clinical Trial for Evaluation of Propranolol and Doxorubicin in the Treatment of Canine Hemangiosarcoma”
Research Update CHF 02534 EY 3 Update: Clinical Trial for Evaluation of Propranolol and Doxorubicin in the Treatment of Canine Hemangiosarcoma
We opened the trial on July 1, 2019. As of June 27, 2021, we have enrolled 18 dogs in the study and no dose limiting toxicities within the initial 21-day assessment period have been observed. Based on these results, we are continuing to enroll dogs at the highest dose of propranolol (1.3 mg/kg) being tested.
Propranolol and doxorubicin levels in the blood from all of the dogs enrolled to date have been analyzed. Continue reading “Research Update CHF 02534 EY 3 Update: Clinical Trial for Evaluation of Propranolol and Doxorubicin in the Treatment of Canine Hemangiosarcoma”
Research Update CHF 02759 Mid-year 2: Reprogramming the Tumor Immune Niche in Canine Hemangiosarcoma
We have made significant progress toward Objective 1 and 2 for this project. Over the past six months, we have continued work to examine molecular and functional changes induced by PIK3CA gene mutations in canine HSA cells. Our data reveal that PI3K inhibitors increase DNA damage greater in HSA cells with PIK3CA mutations than cells without the mutations (i.e., wild-type cells), which depends on a drug dose.

Research Update CHF 02806-MOU MY2: Strategic Prevention of Canine Hemangiosarcoma: Lifetime Follow-Up
The goal of this project is to develop a reliable, accessible, and actionable test to identify dogs at risk for hemangiosarcoma during the earliest stages of the disease and to use a strategic, rationally designed approach to prevent its occurrence in these high-risk dogs before it becomes clinically detrimental and life-threatening. Continue reading “Research Update CHF 02806-MOU MY2: Strategic Prevention of Canine Hemangiosarcoma: Lifetime Follow-Up”
Research Update CHF 02624 Mid-year 3: Embracing Polygenicity of Common Complex Disease in Dogs: Genome-wide Association of Cruciate Ligament Rupture
We have met our Labrador Retriever recruitment for this study over the past year months. We will continue to complete DNA isolation and marker genotyping of the remaining dogs needed for the study as long as the genotyping service remains open under the Covid-19 pandemic. Public engagement with the project continues to be good.

Research Update CHF 02806-MOU MY1: Strategic Prevention of Canine Hemangiosarcoma: Lifetime Follow-Up
The goal for this project is to develop a reliable, accessible, and actionable test to identify dogs at risk for hemangiosarcoma during the earliest stages of disease and to use a strategic, rationally designed approach to prevent its occurrence in these high-risk dogs before it becomes clinically detrimental and life-threatening. The study has two objectives. The first is to determine the most reasonable duration of an SOS test result. In other words, how long can a low-risk SOS test result be trusted and how much time might elapse between a high-risk SOS test result and the development of hemangiosarcoma. The second aim is to continue periodic testing for dogs previously enrolled in the Shine On study whose test result would have placed them in a high-risk category for development of hemangiosarcoma, and to provide eBAT as a strategy for prevention in 12 of these dogs.

Research Update CHF 02519 EY3: Prevalence of Bartonella spp. Infection in Dogs with Cardiac and Splenic Hemangiosarcomas Within and Between Geographic Locations
We are on track to accomplish all of our aims for this study. We were able to obtain the initial set of samples on April 26, 2018 so we had a short delay in starting this study. We have now completed all Year I study aims, with the exception of immunohistochemistry and FISH localization of Bartonella organisms within various cell types.

Research Update CHF 02534 MY 2 Update: Clinical Trial for Evaluation of Propranolol and Doxorubicin in the Treatment of Canine Hemangiosarcoma
During the first 18 months of the trial, we have made progress toward our objectives. The project goals have not been modified.
Our overall objective is to determine a clinically optimal dose and estimate the efficacy of propranolol in dogs with hemangiosarcoma when given as an adjunct to chemotherapy.
