De-Escalation of Breast Radiation Trial for Hormone Sensitive, HER-2 Negative, Oncotype Recurrence Score Less Than or Equal to 18 Breast Cancer (DEBRA)
This Phase III Trial evaluates whether breast conservation surgery and endocrine therapy results in a non-inferior rate of invasive or non-invasive ipsilateral breast tumor recurrence (IBTR) compared to breast conservation with breast radiation and endocrine therapy.
Regional Radiotherapy in Biomarker Low-Risk Node Positive and T3N0 Breast Cancer
The purpose of this study is to compare the effects on low risk breast cancer receiving usual care that includes regional radiation therapy, with receiving no regional radiation therapy. Researchers want to see if not giving this type of radiation treatment works as well at preventing breast cancer from coming …
A Study to Compare Two Surgical Procedures in Individuals With BRCA1 Mutations to Assess Reduced Risk of Ovarian Cancer
This clinical trial studies how well two surgical procedures (bilateral salpingectomy and bilateral salpingo-oophorectomy) work in reducing the risk of ovarian cancer for individuals with BRCA1 mutations. Bilateral salpingectomy involves the surgical removal of fallopian tubes, and bilateral salpingo-oophorectomy involves the surgical removal of both the fallopian tubes and ovaries. …
Testing Radiation and HER2-targeted Therapy Versus HER2-targeted Therapy Alone for Low-risk HER2-positive Breast Cancer
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.
A Study of Milvexian in Participants After an Acute Ischemic Stroke or High-Risk Transient Ischemic Attack- LIBREXIA-STROKE
The purpose of this study is to evaluate whether milvexian compared to placebo reduce the risk of recurrent ischemic stroke.
Pembrolizumab vs. Observation in People With Triple-negative Breast Cancer Who Had a Pathologic Complete Response After Chemotherapy Plus Pembrolizumab
The phase III trial compares the effect of pembrolizumab to observation for the treatment of patients with early-stage triple-negative breast cancer who achieved a pathologic complete response after preoperative chemotherapy in combination with pembrolizumab. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, …
Lung-MAP: A Master Screening Protocol for Previously-Treated Non-Small Cell Lung Cancer
This screening and multi-sub-study randomized phase II/III trial will establish a method for genomic screening of similar large cancer populations followed by assigning and accruing simultaneously to a multi-sub-study hybrid Master Protocol (Lung-MAP). The type of cancer trait (biomarker) will determine to which sub-study, within this protocol, a participant will …
TAPUR: Testing the Use of Food and Drug Administration (FDA) Approved Drugs That Target a Specific Abnormality in a Tumor Gene in People With Advanced Stage Cancer
The purpose of the study is to learn from the real world practice of prescribing targeted therapies to patients with advanced cancer whose tumor harbors a genomic variant known to be a drug target or to predict sensitivity to a drug. NOTE: Due to character limits, the arms section does …
A Study of Orforglipron (LY3502970) in Participants With Obesity or Overweight and at Least One Weight-Related Comorbidity
The main purpose of this study is to see how orforglipron, compared with placebo, helps reduce body weight in participants with obesity or with overweight and at least one other related health condition (excluding type 2 diabetes). This trial is part of the master protocol study J2A-MC-GZPO. Participation in the …
A Master Protocol for Orforglipron (LY3502970) in Participants With Obesity or Overweight With and Without Type 2 Diabetes
The purpose of this Master Protocol is to support two studies to see how well and how safely orforglipron works compared to placebo in participants who have obesity or overweight with or without type 2 diabetes. Participants will be screened for about 4 weeks, after which they will enroll into …
