Summary

The primary purpose of this study is to see if Sym021 is safe and tolerable as monotherapy, in combination with either Sym022 or Sym023, and in Combination with both Sym022 and Sym023 for patients with locally advanced/unresectable or metastatic solid tumor malignancies or lymphomas that are refractory to available therapy or for which no standard therapy is available.

Detailed description

Part 1 of this study will evaluate the safety, tolerability, and dose-limiting toxicities (DLTs) to establish the maximum tolerated dose (MTD) and/or the selected dose of sequential escalating doses of Sym021 when administered once every 2 weeks (Q2W) by IV infusion to patient cohorts with locally advanced/unresectable or metastatic solid tumor malignancies or lymphomas that are refractory to available therapy or for which no standard therapy is available Part 2 of the study will evaluate the safety, tolerability, and DLTs to establish the MTD and/or the selected dose of sequential escalating doses of Sym022 when administered Q2W in combination with a fixed dose of 3 mg/kg of Sym021, each by IV infusion to patient cohorts with locally advanced/unresectable or metastatic solid tumor malignancies or lymphomas that are refractory to available therapy or for which no standard therapy is available Part 3 of the study will evaluate of the safety, tolerability, and DLTs to establish the MTD and/or the selected dose of sequential escalating doses of Sym023 when administered Q2W in combination with fixed doses of 3 mg/kg of Sym021 and either 1, 3 or 5 mg/kg of Sym022, each by IV infusion to patient cohorts with locally advanced/unresectable or metastatic solid tumor malignancies or lymphomas that are refractory to available therapy or for which no standard therapy is available.

Interventions

Type	Name	Description
DRUG	Sym021	Sym021 is a humanized antibody that binds PD-1 with sub-nanomolar affinity and blocks binding of the inhibitory ligands PD-L1 and PD-L2, thus releasing PD-1-mediated inhibition of the immune response.
DRUG	Sym022	Sym022 is a recombinant, fully human antibody that binds LAG-3 and blocks the LAG-3/major histocompatibility complex class II (MHC-II) interaction, thus allowing for increased T-cell proliferation and cytokine production.
DRUG	Sym023	Sym023 is a recombinant, fully human antibody that binds TIM-3 and induces activation of immune cells.
