A Phase 1/2 Study of Zanubrutinib and Tafasitamab in Mantle Cell Lymphoma

Обзор

The main purpose of this study to find the ideal dose for the combination treatment of Zanubrutinib and Tafasitamab in patients with mantle cell lymphoma. Another purpose is to assess how well the combination treatment works in patients with the study disease.
