A Phase 1, Open-Label, Multicenter Trial Investigating the Safety, Tolerability, and Preliminary Antineoplastic Activity of Sym021 (Anti-PD-1) as Monotherapy, in Combination With Either Sym022 (Anti-LAG-3) or Sym023 (Anti-TIM-3), and in Combination With Both Sym022 and Sym023 in Patients With Advanced Solid Tumor Malignancies or Lymphomas

Brief 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.

Interventions
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.
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.
Sym023 is a recombinant, fully human antibody that binds TIM-3 and induces activation of immune cells.
Eligibility Criteria
You may qualify if:
- Male or female patients, ≥ 18 years of age at the time of obtaining informed consent.
- Documented (histologically- or cytologically-proven) solid tumor malignancy that is locally advanced or metastatic; patients with documented lymphoma.

You may not qualify if:
- Women who are pregnant or intending to become pregnant before, during, or within 6 months after the last dose of study drug; women who are breastfeeding; persons of childbearing potential and not willing to use a highly effective method of contraception.
- Central nervous system (CNS) malignancies; patients with known, untreated CNS or leptomeningeal metastases, or spinal cord compression, patients with any of the above not controlled by prior surgery or radiotherapy, or patients with symptoms suggesting CNS involvement for which treatment is required.
- Hematologic malignancies other than lymphoma.
- Active thrombosis, or a history of deep vein thrombosis (DVT) or pulmonary embolism (PE) within 4 weeks prior to Cycle 1/Day 1 (C1/D1) unless adequately treated and considered stable.

- History of organ transplantation (e.g., stem cell or solid organ transplant).
- History of significant toxicities associated with previous administration of immune checkpoint inhibitors that necessitated permanent discontinuation of that therapy.
