The purpose of this study is to evaluate the safety, tolerability and clinical activity of RO6870810 in combination with venetoclax and when co-administered with rituximab in participants with relapse/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) and/or high-grade B-cell lymphoma with myelocytomatosis oncogene (MYC) and/or B-cell lymphoma 2 (BCL2) and/or B-cell lymphoma 6 (BCL6) gene rearrangements (HGBL-DH/TH).
Open-Label, Dose Escalation/Expansion Phase Ib Study to Evaluate the Safety, Pharmacokinetics, and Clinical Activity of the Combination of RO6870810 and Venetoclax, With or Without Rituximab, in Patients With Relapsed/Refractory Diffuse Large B-Cell Lymphoma (DLBCL) and/or High-Grade B-Cell Lymphoma With MYC and/or BCL2 and/or BCL6 Gene Rearrangements
- Cooperative Oncology Group (ECOG) Performance Status of 0, 1, or 2.
- Life expectancy >3 months as per investigator's assessment.
- Part 1 and Part 2 Group 1: Participantts with diffuse large B-cell lymphoma (DLBCL) relapsed or refractory to ≥ 1 course of chemotherapy including an anti-CD20 monoclonal antibody, and not eligible for autologous stem cell transplantation (ASCT) (including due to chemorefractory disease). Participants with transformed FL are eligible, provided DLBCL or HGBL-DH/TH histology is biopsy-confirmed prior to study entry and a treatment regimen as described above has been administered. The Sponsor retains the option to limit the number of participants enrolled with transformed FL.
Part 2, Group 2: Patients identified with DE-DLBCL (expression MYC ≥40%, BCL2 > 50%) and or HGBL-DH/TH, relapsed or refractory to >= 1 course of chemotherapy including an anti-CD20 monoclonal antibody, and not eligible for ASCT (including due to chemorefractory disease). Patients with transformed follicular lymphoma (FL) are eligible, provided DE-DLBCL and/or HGBL-DH/TH histology is biopsy-confirmed prior to study entry and a treatment regimen as described above has been administered. The Sponsor retains the option to limit the number of participants enrolled with transformed FL.
- Part 1 and Part 2: Willing to provide the protocol specified tumor biopsy(ies): at screening a fresh biopsy (if no archival biopsy tissue of less than 3 months prior to treatment and without intercurrent treatment is available); Part 2: Willing to provide an additional biopsy on Cycle 2 Day 15 (+ 2 days).
- Acceptable liver function, as specified below:
- Total bilirubin ≤ 2 times upper limit of normal (ULN). (Participants with known Gilbert's disease who has serum bilirubin ≤ 3 × ULN may be enrolled).
- Aspartate transaminase (AST; SGOT), alanine transaminase (ALT; SGPT) ≤ 2.5 × ULN, (or ≤ 5 × ULN if tumor involvement (liver) is present).
- Gamma-glutamyl transferase (GGT) alkaline phosphatase ≤ 2.5 × ULN.
- Acceptable renal function, as specified below:
• Creatinine clearance (CrCl) calculated by Cockroft-Gault formula of ≥ 60 mL/min.
- Acceptable hematologic status (growth factors cannot be used within the previous 7 days), as specified below:
- Absolute neutrophil count (ANC) ≥ 1000 cells/μL
- Hemoglobin ≥ 9 g/dL
- Platelet count ≥ 75,000 (platelets/μL)
- Uncontrolled symptomatic hypercalcemia.
- Acceptable coagulation status, as specified below:
- Prothrombin time (PT) and partial thromboplastin time (PTT) ≤ 1.2 × ULN (unless receiving anticoagulation therapy, if receiving anticoagulation therapy, eligibility will be based upon international normalized ratio [INR]).
- INR ≤ 1.6 (unless receiving anticoagulation therapy).
- If receiving warfarin: INR ≤ 3.0 and no active bleeding (i.e., no bleeding within 14 days prior to first dose of study therapy).
- Acceptable method of contraception
- Current central nervous system (CNS) lymphoma or leptomeningeal infiltration.
- New York Heart Association (NYHA) Class III or IV cardiac disease, myocardial infarction, within the past 6 months, unstable arrhythmia, or known pericardial disease.
- Fredericia-corrected QT interval (QTcF) >470 msec (female) or >450 msec (male), or history of congenital long QT syndrome.
- Any electrocardiogram (ECG) abnormality, which in the opinion of the Investigator would preclude safe participation in the study.

- Serious non-malignant disease that could compromise protocol objectives in the opinion of the Investigator and/or the Sponsor.
- History of progressive multifocal leukoencephalopathy (PML).
- History of other malignancy within 2 years prior to screening, except for ductal carcinoma in situ not requiring chemotherapy, appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, low-grade, localized prostate cancer (Gleason score ≤ 7) not requiring treatment or appropriately treated Stage I uterine cancer.
