Brief Summary: The aim of the CLL-RT1 trial is to evaluate the efficacy and safety of zanubrutinib (BGB-3111), a BTK inhibitor plus tislelizumab (BGB-A317), a PD1 inhibitor for treatment of patients with Richter Transformation
Detailed Description: Richter Transformation (RT) remains one of the biggest challenges in the treatment and management of CLL. While considerable progress has been made in the treatment of CLL, the prognosis of CLL patients with malignant disease transformation still is very poor and reported median OS is between 6 to 8 months. Conventional approaches with chemo- and chemoimmunotherapy have largely failed to improve response rates in RT patients. However, as the established treatment approach for de-novo Diffuse Large B Cell Lymphoma (DLBCL) is chemoimmunotherapy with a combination of Rituximab, Cyclophosphamid, Hydroxydaunorubicin, Vincristin and Prednisolon (R-CHOP), this has become the most commonly used regimen for lack of alternative strategies, despite poor efficacy. Patients being fit enough for allogeneic transplantation are undergoing this procedure after induction with R-CHOP. However, the majority of patients are not suitable for transplantation and relapse quickly. Hence, there is urgent need to improve therapy of RT by testing new compounds and combinations for treatment of this disease. Based on the available preclinical and preliminary clinical data on checkpoint inhibition plus Bruton's tyrosine (BTK) inhibition, the current trial will systematically assess the safety and toxicity of tislelizumab, a programmed cell death protein 1 (PD-1) inhibitor, plus zanubrutinib, a BTK inhibitor in patients with RT.
