A Study to Learn How Avacincaptad Pegol (Izervay™) is Used in Clinical Practice in People Who Have Geographic Atrophy
Recruiting
This study is for people who have geographic atrophy due to age-related macular degeneration (AMD). AMD happens when the macula, the light-sensitive layer at the back of the eye called the retina, becomes damaged and causes a person's central vision to worsen. Geographic atrophy is an advanced form of AMD where cells in the retina waste away and die. Over time this can lead to permanent loss of vision. Avacincaptad pegol can help slow down the worsening or progression of geographic atrophy. Ava... Read More

Recruiting
This is a study to assess the efficacy, safety, and tolerability of IMVT-1402 in adult participants with Graves' disease (GD) who are hyperthyroid despite antithyroid drug (ATD) treatment. The primary objective of this study is to evaluate the efficacy of IMVT-1402 versus placebo as assessed by T3 (total triiodothyronine \[T3\] or free triiodothyronine \[FT3\]), free thyroxine (FT4), thyroid-stimulating hormone (TSH), and ATD dose at Week 26.

Testing the Addition of an Anti-Cancer Drug, Abemaciclib, to the Usual Chemotherapy Treatment (5-Fluorouracil) for Metastatic, Refractory Colorectal Cancer
Recruiting
This phase I trial tests the safety, side effects, and best dose of abemaciclib in combination with 5-fluorouracil and how well it works in treating patients with colorectal cancer that has spread from where it first started (primary site) to other places in the body (metastatic) and that has not responded to treatment (refractory). Abemaciclib, a type of cyclin-dependent kinase inhibitor, blocks certain proteins, which may help keep tumor cells from growing. 5-fluorouracil, a type of antimetabo... Read More

A Study of Pembrolizumab (MK-3475) With or Without Intismeran Autogene (V940) in Participants With Non-small Cell Lung Cancer (V940-009/INTerpath-009)
Recruiting
The goal of this study is to learn if people who receive intismeran autogene and pembrolizumab after surgery are cancer-free longer than people who receive placebo and pembrolizumab. Researchers want to know if giving intismeran autogene and pembrolizumab after surgery can help prevent the cancer from coming back in people with non-small cell lung cancer (NSCLC) whose tumors did not respond completely to treatment before surgery (neoadjuvant treatment).
