Description
Summary
This is an open-label, multi-center Phase 1b clinical study of oral AS-1763 in patients with CLL/SLL or B-cell NHL who have failed or are intolerant to ≥2 lines of systemic therapy.
Official Title
A Phase 1b Study of Oral AS-1763 in Patients With Previously Treated Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma or Non-Hodgkin Lymphoma
Details
This study consists of 2 parts.
Dose escalation part will enroll up to 27 patients to evaluate safety profile and tolerance of AS-1763 using 3+3 design. The starting dose of AS-1763 in oral tablet form is 100 mg twice daily (200 mg/day). Dose escalation will continue up to the planned maximum dose level or until the maximum tolerated dose (MTD) has been identified.
Dose expansion part will enroll up to 48 CLL/SLL patients (Cohort 1), up to 35 NHL patients (Cohort 2), and up to 10 patients with prior pirtobrutinib treatment for an approved indication (Cohort 3). The first 30 patients in each Cohort 1 or 2 will be allocated to three dose levels (n=10 at each dose level) which will be selected based on the data from dose escalation. Preliminary efficacy and safety data from the first 30 patients in one of cohorts will be used to identify the provisional recommended Phase 2 dose (RP2D) level. Thereafter, up to a further 18 patients for Cohort 1 and up to a further 5 patients for Cohort 2 will be enrolled and allocated to the provisional RP2D level. Cohort 3 will be enrolled in parallel with Cohorts 1 and 2 and will be allocated to up to two dose levels (either n=10 at a single dose level or n=5 at each of 2 dose levels).
Study assessments will continue for 24 cycles (1 cycle = 28 days) or until disease progression, occurrence of unacceptable toxicity, or discontinuation because of other reasons. Patients will then be followed for survival status for a further 2 years.
RP2D will be determined based on all the data generated in the study.
