A Clinical Study of Molnupiravir to Prevent Severe Illness From Coronavirus Disease 2019 (COVID-19) in People Who Are High Risk (MK-4482-023)
Recruiting
Researchers are looking for other ways to prevent severe illness from COVID-19. COVID-19 is a virus that most often causes mild flu or cold-like symptoms. However, people with certain health conditions or other factors have a high risk (chance) of getting severely ill from COVID-19, which can require a hospital stay or lead to death. Some people who are high risk for severe illness may be unable to take certain treatments for COVID-19 because they are not available to them, or they take other me... Read More

A Plant-Based Whole-Foods Meal Delivery Service for Patients With Multiple Myeloma Undergoing Autologous Hematopoietic Cell Transplant
Recruiting
This clinical trial evaluates the impact of a plant-based whole-foods delivery service on the microbiome in patients with multiple myeloma undergoing an autologous hematopoietic cell transplant. An autologous hematopoietic cell transplant is a procedure in which blood-forming stem cells (cells from which all blood cells develop) are removed, stored, and later given back to the same person. Loss of microbial diversity within the intestinal tract has been associated with poor outcomes for patients... Read More

Recruiting
The purpose of this study is to evaluate efficacy and safety of Dato-DXd in combination with rilvegostomig or rilvegostomig monotherapy compared with pembrolizumab monotherapy as a first line therapy in participants with locally advanced or metastatic non-squamous NSCLC with high PD-L1 expression (TC ≥ 50%) and without actionable genomic alterations.

Venetoclax and HMA Treatment of Older and Unfit Adults With FLT3 Mutated Acute Myeloid Leukemia (AML) (A MyeloMATCH Treatment Trial)
Recruiting
This phase II MyeloMATCH treatment trial compares the usual treatment of azacitidine and venetoclax to the combination treatment of azacitidine, venetoclax and gilteritinib in treating older and unfit patients with acute myeloid leukemia and FLT3 mutations. Azacitidine is a drug that is absorbed into DNA and leads to the activation of cancer suppressor genes, which are genes that help control cell growth. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may... Read More
