Docetaxel with or without Bintrafusp Alfa for the Treatment of Advanced Non-small Cell Lung Cancer

Trial Status: Approved

This phase II trial studies how well docetaxel works with or without bintrafusp alfa in treating patients with non-small cell lung cancer that has spread to other places in the body (advanced). Chemotherapy drugs, such as docetaxel, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with bintrafusp alfa, may induce changes in body’s immune system and may interfere with the ability of tumor cells to grow and spread. Giving docetaxel and bintrafusp alfa in combination may work better in treating non small-cell lung cancer compared to docetaxel alone.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive docetaxel intravenously (IV) over 1 hour and bintrafusp alfa IV over 60 minutes on day 1. Treatment repeats every 3 weeks for 4 cycles in the absence of disease progression or unacceptable toxicity. Patients then receive bintrafusp alfa IV over 60 minutes on day 1. Cycles repeat every 3 weeks for up to 2 years in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive docetaxel IV over 1 hour on day 1. Cycles repeat every 3 weeks in the absence of disease progression or unacceptable toxicity. Patients who experience disease progression may crossover to Arm I and receive bintrafusp alfa alone.

After completion of study treatment, patients are followed up at 30 days and then every 3 months for 5 years.
