Tafasitamab and Rituximab for the Treatment of Newly Diagnosed Follicular Lymphoma

Официальное название

TREND-FL: Tafasitamab and Rituximab to Enhance Outcomes in Patients With Newly Diagnosed Follicular Lymphoma

Обзор

This phase II trial tests how well tafasitamab and rituximab works for the treatment of newly diagnosed follicular lymphoma. Tafasitamab is a monoclonal antibody. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Giving tadasitamab and rituximab may work well to treat patients with newly diagnosed follicular lymphoma.

Подробное описание

OUTLINE:

CYCLES 1-3: Patients receive rituximab intravenously (IV) on day 1 and tafasitamab IV on days 1, 8, 15 and 22 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

CYCLES 4-6; Patients receive rituximab IV on day 1 and tafasitamab IV on days 1 and 15 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Patients then undergo disease assessment. Patients with complete response undergo active surveillance. Patients with less than complete response go on to receive cycles 7-12.

CYCLES 7-12: Patients receive tafasitamab IV on days 1 and 15 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Patients undergo positron emission tomography (PET) scan, computed tomography (CT) scan, bone marrow biopsy and aspiration and blood sample collection throughout the study.

After completion of study treatment, patients are followed up periodically for up to 5 years.
