Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to determine the safety and tolerability of GS-0189 (formerly FSI-189) as monotherapy and in combination with rituximab in participants with relapsed/refractory (R/R) non-Hodgkin lymphoma (NHL).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study will consist of 5 parts: 1) an initial Monotherapy Dose Escalation (MDE) part, 2) a Combination Dose Escalation (CDE) part, 3) a Pharmacokinetic (PK) Evaluation part, 4) an Alternate Schedule Evaluation (ASE) part and 5) a diffuse large B-cell lymphoma (DLBCL) Expansion part.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

GS-0189 (Monotherapy Dose Escalation, MDE)

Relapsed/refractory (R/R) non-Hodgkin lymphoma (NHL) participants will receive GS-0189 doses of 10, 30, or 100 mg every 2 weeks.

Group Type EXPERIMENTAL

GS-0189

Intervention Type DRUG

GS-0189 will be administered intravenously.

GS-0189 + Rituximab (Combination Dose Escalation, CDE)

R/R NHL participants will receive GS-0189 doses of 100, 300, 1000, 2000, and 3000 mg in combination with rituximab at 375 mg/m\^2.

Group Type EXPERIMENTAL

GS-0189

Intervention Type DRUG

GS-0189 will be administered intravenously.

Rituximab

Intervention Type DRUG

Rituximab will be administered intravenously.

GS-0189 + Rituximab (Pharmacokinetic (PK) Evaluation)

R/R NHL participants will receive GS-0189 dose of up to 30 mg followed by the highest designated safe dose from the Combination Dose Escalation cohort (CDE) in combination with rituximab at 375 mg/m\^2.

Group Type EXPERIMENTAL

GS-0189

Intervention Type DRUG

GS-0189 will be administered intravenously.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* DLBCL, follicular lymphoma (FL), mantle cell lymphoma (MCL), or marginal zone lymphoma (MZL) relapsed/refractory (R/R) to at least 2 prior lines of therapy. Prior autologous hematopoietic cell transplantation and individuals with transformed lymphomas are permitted. Individuals must be at least 3 months out from prior autologous hematopoietic cell transplantation. Individuals with indolent lymphomas must be candidates for systemic treatment in the judgment of the treating physician.
* In the DLBCL Expansion part: DLBCL that is relapsed or refractory to at least 2 prior lines of therapy. Prior autologous hematopoietic cell transplantation and individuals with transformed lymphomas are permitted.
* Eastern Cooperative Oncology Group (ECOG) score of 0 to 2.
* For the DLBCL expansion cohort, disease must be measurable for response per Lugano criteria. For all other cohorts, disease must be measurable or assessable for response per Lugano criteria.
* Exhibit acceptable hematopoietic, liver, renal, and coagulation function as assessed by laboratory tests.

Exclusion Criteria

* Individuals with active brain metastases (Individuals with stable treated central nervous system (CNS) lesions who are off corticosteroid therapy for at least 3 weeks are not considered active.
* Individuals with Burkitt's lymphoma.
* Prior treatment with a chimeric antigen receptor (CAR) T-cell therapy ≤ 90 days from first dose of study drug.
* Prior allogeneic stem cell transplant.
* Previous anticancer therapy including chemotherapy, hormonal therapy, and investigational agents within 3 weeks or at least 4 half-lives (up to a maximum of 4 weeks), whichever is longer, prior to first dose of study drug.
* Known active or chronic hepatitis B or C infection or human immunodeficiency virus.
* Prior treatment with CD47 or signal regulatory protein alpha (SIRPα)-targeting agents.
* Hypersensitivity to the active substance, to murine proteins, or to any of the other excipients of rituximab
* Significant medical diseases or conditions, as assessed by the Investigator and Sponsor, that would substantially increase the risk:benefit ratio of participating in the study.
* Rituximab-containing cohorts only: Receipt of live/attenuated vaccines within 30 days of rituximab dosing
* Has persisting toxicity related to prior therapy of Grade \> 1 in severity per National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), Version 5.0.
