2. As chronic lymphocytic leukemia (CLL) proliferation and survival depends on the microenvironment, we used murine models to assess the efficacy of the BTK inhibitor acalabrutinib combined with the PI3Kdelta inhibitor ACP-319 in vivo.The combination of acalabrutinib and ACP-319 was superior to single-agent treatment in a murine CLL model PMID: 28645939
