Testing Radiation and HER2-targeted Therapy Versus HER2-targeted Therapy Alone for Low-risk HER2-positive Breast Cancer
Recruiting
This Phase III trial compares the recurrence-free interval (RFI) among patients with early-stage, low risk HER2+ breast cancer who undergo breast conserving surgery and receive HER2-directed therapy, and are randomized to not receive adjuvant breast radiotherapy versus those who are randomized to receive adjuvant radiotherapy per the standard of care.

Buffered Lidocaine for Reducing Pain in Patients Undergoing Prostate Biopsy, BURN Trial
Recruiting
This phase I/II trial examines if buffered lidocaine reduces the pain that patients may experience during prostate biopsy. Prostate biopsies are typically performed awake, in the office, with only local anesthetic. As a result, many patients note considerable pain during these procedures. Local anesthetics such as lidocaine are typically acidic, which is thought to cause pain and burning during infiltration (injection). As a result, buffered local anesthetic has become the standard of care (SOC)... Read More

Chemotherapy Combined With Immunotherapy Versus Immunotherapy Alone for Older Adults With Stage IIIB-IV Lung Cancer, The ACHIEVE Trial
Recruiting
This phase III trial compares the effect of adding chemotherapy to immunotherapy (pembrolizumab) versus immunotherapy alone in treating patients with stage IIIB-IV lung cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividin... Read More
