A Phase I Study of Intravenous CHO-H01 in Patients With Refractory or Relapsed Follicular Lymphoma

This is a single-arm open label trial to explore the tolerability, safety, PK, PD, and anti-tumor activity of various doses and schedules of CHO-H01 administered as monotherapy in subjects with follicular lymphoma. This is not an MTD study, but an evaluation of optimum biological activity. Groups of 6 subjects are planned for each cohort. The first 3 patients of each cohort will be evaluated to determine if it is appropriate to proceed with the additional 3 patients at that dose and schedule. Schema 1: 1 mg/kg administered on D1 of Cycle 1 and D1 of subsequent 28 day cycles. Up to 6 cycles total are planned per subject. Schema 2-3 Details to be determined after analysis of first 3-6 patients treated on Schema 1. Doses may be either escalated or de-escalated, or modified for Cycles 2-6 relative to Cycle 1. Schedules to be explored could include multiple doses with the first cycle: D1, D8 of 28 day cycles and D1, D8, D15 of 28 days cycles. In no case will individual doses exceed 10mg/kg. Decisions on whether to proceed with a schema and details of selected dose and schedule will be made during cohort data review meetings by a Clinical-Scientific Review Team (CSRT) comprised of the trial investigators and Medical/Clinical and Safety representatives from the Sponsor. Ad hoc members will be consulted as needed.
