A Study of Disitamab Vedotin With Other Anticancer Drugs in Solid Tumors
Recruiting
This clinical trial is studying solid tumor cancers. A solid tumor is one that starts in part of your body like your lungs or liver instead of your blood. Once they've grown bigger in one spot or spread to other parts of the body, they're harder to treat. This is called advanced or metastatic cancer. Participants in this study must have breast cancer or gastric cancer. Participants must have tumors that have HER2 on them. This allows the cancer to grow more quickly or spread faster. There are f... Read More

A Trial to Learn if Odronextamab Combined With Lenalidomide is Safe and Works Better Than Rituximab Combined With Lenalidomide in Adult Participants With Follicular Lymphoma and Marginal Zone Lymphoma
Recruiting
This study is researching an experimental drug called odronextamab (referred to as study drug), in combination with lenalidomide. The study is focused on participants who have one of two types of cancer: follicular lymphoma (FL) or marginal zone lymphoma (MZL) that has come back after treatment (called "relapsed"), or did not respond to treatment (called "refractory"). FL and MZL are subtypes of Non-Hodgkin 's lymphoma (NHL). This study will be made up of two parts (Part 1 not randomized, Part... Read More

A Study of SGN-CEACAM5C in Adults With Advanced Solid Tumors
Recruiting
This clinical trial is studying advanced solid tumors. Solid tumors are cancers that start in a part of your body like your lungs or liver instead of your blood. Once tumors have grown bigger in one place but haven't spread, they're called locally advanced. If your cancer has spread to other parts of your body, it's called metastatic. When a cancer has gotten so big it can't easily be removed or has spread to other parts of the body, it is called unresectable. These types of cancer are harder to... Read More

A Randomized Comparison of Stage-Based Care Versus Risk Factor-Based Care for Prevention of Cardiovascular Events
Recruiting
TRANSFORM is a prospective, randomized, open blinded endpoint (PROBE), event-driven, pragmatic trial in patients who are at increased risk for atherosclerotic cardiovascular (CV) disease but with no known symptomatic CV disease. The trial tests the hypothesis that a Cleerly Coronary Artery Disease (CAD) Staging System-based care strategy reduces CV events compared with risk factor-based care.

A Study to Learn More About the Safety and Effects of Felzartamab in Adults With Lupus Nephritis Aged 18 to 75 Years Old
Recruiting
In this study, researchers will learn more about the use of felzartamab in people with active lupus nephritis, also known as LN. In people with LN, antibodies build up in the glomeruli of the kidneys. Antibodies are proteins in the blood used by the immune system to fight infection. Glomeruli are small filters that remove waste and extra fluid from the blood. This buildup leads to inflammation and damage to the kidneys. Kidney damage can lead to too much protein and blood leaking into the urine... Read More

A Study of Sigvotatug Vedotin Versus Docetaxel in Previously Treated Non-small Cell Lung Cancer
Recruiting
This clinical trial is studying nonsquamous non-small cell lung cancer (NSCLC). Participants in this study must have cancer that has spread through their body or can't be removed with surgery. Participants in this study must have been treated with no more than a platinum-based chemotherapy and an anti-PD-(L)1 drug. Participants with tumors that have certain treatable genomic alterations must have had at least 1 drug for that genomic alteration, in addition to platinum-based chemotherapy. This c... Read More

Recruiting
This study will test the safety of a drug called PF-08046052/SGN-EGFRd2 in participants with advanced solid tumors. It will also study the side effects of this drug. A side effect is anything a drug does to the body besides treating the disease. Participants will have cancer that cannot be removed (unresectable) or has spread through the body (metastatic). This study will have three parts. Parts A and B of the study will find out how much PF-08046052/SGN-EGFRd2 should be given to participants.... Read More

The purpose of this study is to evaluate the efficacy and safety of lutetium (177Lu) vipivotide tetraxetan (AAA617) in participants with oligometastatic prostate cancer (OMPC) progressing after definitive therapy to their primary tumor. The data generated from this study will provide evidence for the treatment of AAA617 in early-stage prostate cancer patients to control recurrent tumor from progressing to fatal metastatic disease while preserving quality of life by delaying treatment with androg...

No Opioids vs. Minimal Opioids Following Inguinal Hernia Repair
Recruiting
The investigators hypothesize that not prescribing opioids after uncomplicated, outpatient IHR will be non-inferior to prescribing opioids (5 tablets of Oxycodone, 5mg; or surgeon preference for intolerance) with respect to requests for opioid refills. Additionally, the investigators believe there will be no significant difference in postoperative readmission for pain quality of life at 30 days in either group.
