Join Thousands Waiting for Retatrutide
Retatrutide could change the weight loss landscape. Unlike semaglutide or tirzepatide, it activates three hormone receptors simultaneously — and early data shows it:
✅ Outpaced existing GLP-1 medications for weight loss in clinical trials
✅ Improved blood sugar, blood pressure, and cholesterol beyond weight loss alone
✅ Delivered results with a simple once-weekly injection
✅ Now in Phase 3 trials with FDA submission expected in the next 1–2 years

Intravesical BCG vs GEMDOCE in NMIBC
Recruiting
The study hypothesis is that BCG naïve non-muscle invasive bladder cancer (NMIBC) patients treated with intravesical Gemcitabine + Docetaxel (GEMDOCE) will result in a non-inferior event-free survival (EFS) compared to standard treatment with intravesical BCG. The purpose of this study is to test whether Gemcitabine + Docetaxel is a better or worse treatment than the usual BCG therapy approach. The primary objective of this study is to determine the event free survival (EFS) of BCG-naïve high gr... Read More

Remotely Delivered, Community-Aligned Weight Loss Interventions Among Breast Cancer Survivors, ¡Vida! Trial
Recruiting
This clinical trial evaluates remotely delivered, community-aligned weight loss interventions in Latina breast cancer survivors. Breast cancer is the second leading cause of cancer death among women in the US. There are population differences in breast cancer mortality, based on specific risk factors, including obesity. Cancer is the leading cause of death among Latinos, and among Latinas, breast cancer is the leading cause of cancer death. An estimated 80% of Latinas in the United States have o... Read More

A Study of Intismeran Autogene (V940) Plus Pembrolizumab (MK-3475) Versus Placebo Plus Pembrolizumab in Participants With Non-small Cell Lung Cancer (V940-002)
Recruiting
The goal of this study is to evaluate intismeran autogene plus pembrolizumab versus placebo plus pembrolizumab for the adjuvant treatment of margin negative, completely resected Stage II, IIIA, IIIB (with nodal involvement \[N2\]) non-small cell lung cancer (NSCLC). The primary hypothesis is that intismeran autogene plus pembrolizumab is superior to placebo plus pembrolizumab with respect to disease-free survival (DFS) as assessed by the investigator.

Precision-Based Genomics in Prostate Cancer
Recruiting
Background:
Prostate cancer is the most common cancer and the second leading cause of death in males in the United States. Researchers want to find additional gene mutations that may increase a man s risk for prostate cancer and may affect how aggressive the disease is.
Objective:
To look at gene mutations in men with prostate cancer as well as the course of their disease to better understand how gene mutations relate to the way the cancer progresses and responds to treatment.

Testing Osimertinib as a Treatment for Lung Cancers With an EGFR Exon 20 Change
Recruiting
This phase II trial studies how well osimertinib works in treating patients with non-small cell lung cancer with EGFR exon 20 insertion mutation that is stage IIIB-IV or has come back after a period of improvement (recurrent). Osimertinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Larotrectinib to Enhance RAI Avidity in Differentiated Thyroid Cancer
Recruiting
Papillary thyroid cancer (PTC) is the most common form of differentiated thyroid cancer (DTC). The traditional first line treatment for patients with advanced DTC after surgical resection is radioactive iodine (RAI) therapy. However, less than a quarter of patients with lung metastases will achieve a complete response to RAI therapy, and this therapy carries the risk of pulmonary fibrosis and an increasingly recognized risk of secondary malignancies.

Targeted Therapy to Increase RAI Uptake in Metastatic DTC
Recruiting
Papillary thyroid cancer (PTC) is a common type of differentiated thyroid cancer (DTC) in children and represents the second most common cancer in adolescent females. Recently targeted drugs that block many of the genetic drivers of DTC have become available. While Investigators know that these drugs shrink DTC tumors in many cases, the impact on radioactive iodine (RAI) avidity has not been systematically studied.
