Clinical Trials For Disease Areas in Connecticut 

Connecticut is a hotspot for medical innovation. With renowned institutions, like Grove Hill Clinical Research, experts are leading the way in various fields. Our state excels in the study of a wide range of diseases.

Clinical research trials in Connecticut are committed to pioneering investigations on cancer research, neurological disorders, mental health, chronic disease treatment, microbiology, and more. These research strengths make it a key player in the field of medicine.

Recently, Connecticut experts explained that another experimental drug for Alzheimer’s can slow a patient’s memory decline by roughly 4 to 7 months. The drug donanemab is waiting for FDA approval. If cleared, it could be a promising treatment for the disease.

Here is a list of active and future trials that could offer valuable results.

T-DM1 and Tucatinib Compared with T-DM1 Alone in Preventing Relapses in People with High Risk HER2-Positive Breast Cancer, the CompassHER2 RD Trial
Recruiting
This phase III trial studies how well trastuzumab emtansine (T-DM1) and tucatinib work in preventing breast cancer from coming back (relapsing) in patients with high risk, HER2 positive breast cancer. T-DM1 is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called DM1. Trastuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as HER2 receptors, and delivers DM1 to kill them. Tucatinib may stop t... Read More

Medical Discoveries and Innovation in Connecticut

Connecticut has many dedicated healthcare professionals and research institutions that have made notable contributions to health and medicine. Here is a list of some of the discoveries the state is famous for.

  • Discovery of Lyme Disease: In the 1970s, Dr. Allen Steere and his mentor Stephen Malawista discovered and named Lyme disease. At the time, Dr. Steere was working at Yale University in Connecticut. Since then, he has published about 300 scholarly articles on the infection. 
  • Advancements in Cardiovascular Surgery: Dr. William W. L. Glenn was a renowned heart surgeon. He invented a technique to treat congenital heart disease. He also participated in creating the early version of an artificial heart. From 1948 to 1975, he was the chief of heart surgery at Yale University. 
  • The First Artificial Heart: Dr. Robert K. Jarvik is a Connecticut-based physician who invented the first permanently implantable artificial heart. This groundbreaking medical device paved the way for future advancements in heart transplantation and cardiovascular care.
