Arms

experimental: Dose Escalation

Subjects in this arm will participate in one (1) of eight (8) escalating defined dose level cohorts. Subjects will receive up to 54 weeks of LTZ-301 intravenously.

experimental: Backfill Expansion

Subjects may be dosed at levels previously declared safe to further explore safety, tolerability, and clinical activity at particular dose levels.

experimental: Expansion

A dose level will be selected to enroll additional subjects to explore safety, tolerability, and clinical activity for a selected lymphoma type.

Interventions

LTZ-301

LTZ-301 will be dosed IV, in initial 28 day cycles. First cycle dosing is every week. Second through fifth cycles are dosed every 2 weeks. Sixth cycle and beyond are 21 day cycles, and are dosed once every 3 weeks.
