Conditions

B Cell Malignancies and Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma

Brief summary

Dose Expansion, Part 2 - ORR, defined as the proportion of subjects achieving CR, CRi, nodular partial response (nPR), partial response (PR), or PR with lymphocytosis (PR-L) at any time while on the study based on iwCLL response criteria, as assessed by investigators.

Detailed description

CR/CRi rate, defined as the proportion of subjects achieving CR/CRi based on iwCLL response criteria, DOR, defined as time from initial response to disease progression or death from any cause, Analyses of the safety and tolerability endpoints will include the following measurements or assessments: − Incidence, nature, severity of treatment-emergent AEs (TEAEs), and deaths, including the cause of death, from Screening up to the End of Treatment visit − Clinical laboratory measurements, ECG measures, vital signs, ECOG performance status from Screening up to the End of Treatment visit, • TL-895 PK parameters, including but not limited to: − Predose concentration (C0h) − Concentration at 2 hours post-dose (C2h) − Cmax − Tmax − AUC, BTK occupancy in PBMCs
