A Dose Escalation Study of Glofitamab (RO7082859) as a Single Agent and in Combination With Obinutuzumab, Administered After a Fixed, Single Pre-treatment Dose of Obinutuzumab in Participants With Relapsed/Refractory B-cell Non-hodgkin's Lymphoma

Running, not enrolling · Phase 1/Phase 2

Conditions studied: Non-Hodgkin's Lymphoma

In brief

This is a Phase I/II, multicenter, open-label, dose-escalation study designed to evaluate the efficacy, safety, tolerability and pharmacokinetics (PK) of a novel T-Cell bispecific (TCB), glofitamab, administered by intravenous (IV) infusion as a single agent and in combination with obinutuzumab, following pre-treatment with a one-time, fixed dose of obinutuzumab. This entry-into-human (EIH) study is divided in 3 parts: dose escalation (Parts I and II) and dose expansion (Part III). Single-participant dose-escalation cohorts will be used in Part I, followed by conversion to multiple participant dose-escalation cohorts (Part II), in order to define a tentative maximum tolerated dose (MTD) or optimal biological dose (OBD). The expansion cohorts (Part III) will be initiated when the tentative MTD/OBD is defined, to further evaluate the safety, PK and therapeutic activity of glofitamab.

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Depending upon study part, a history or status of: 1) a histologically-confirmed hematological malignancy that is expected to express cluster of differentiation (CD)20; 2) relapse after or failure to respond to at least one prior treatment regimen; and 3) no available treatment options that are expected to prolong survival (e.g., standard chemotherapy or autologous stem cell transplant [ASCT])
• Measurable disease, defined as at least one bi-dimensionally measurable nodal lesion, defined as > 1.5 cm in its longest dimension, or at least one bi-dimensionally measurable extranodal lesion, defined as > 1.0 cm in its longest dimension
• Able to provide a tumor tissue pretreatment biopsy at last relapse or during screening from a safely accessible site, per investigator determination, providing the patient has more than one measurable target lesion
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
• Life expectancy of >/=12 weeks
• AEs from prior anti-cancer therapy must have resolved to Grade less than or equal to (</=) 1
• Adequate liver, hematological and renal function
• Negative serologic or polymerase chain reaction (PCR) test results for acute or chronic Hepatitis B virus (HBV) infection
• Negative test results for Hepatitis C virus (HCV) and human immunodeficiency virus (HIV)
• Negative serum pregnancy test within 7 days prior to study treatment in women of childbearing potential. Women who are not of childbearing potential who are considered to be post-menopausal (at least 12 months of non-therapy amenorrhea) or surgically sterile (absence of ovaries and/or uterus) are not required to have a pregnancy test

You may not qualify if…

• Inability to comply with protocol mandated hospitalizations and restrictions
• Participants with chronic lymphocytic leukemia (CLL), Burkitt lymphoma and lymphoplasmacytic lymphoma
• Participants with a known or suspected history of hemophagocytic lymphohistiocytosis (HLH)
• Participants with acute bacterial, viral, or fungal infection at baseline, confirmed by a positive blood culture within 72 hours prior to obinutuzumab infusion or by clinical judgment in the absence of a positive blood culture
• Participants with known active infection, or reactivation of a latent infection, whether bacterial, viral, fungal, mycobacterial, or other pathogens or any major episode of infection requiring hospitalization or treatment with IV antibiotics within 4 weeks of dosing
• Prior treatment with systemic immunotherapeutic agents, including, but not limited to, radio-immunoconjugates, antibody-drug conjugates, immune/cytokines and monoclonal antibodies (e.g., anti-cytotoxic T-lymphocyte-associated protein 4 [anti-CTLA4], anti-programmed death 1 [anti-PD1] and anti-programmed death ligand 1 [anti-PDL1]) within 4 weeks or five half-lives of the drug, whichever is shorter, before obinutuzumab infusion on Cycle 1 Day -7
• History of treatment-emergent immune-related AEs associated with prior immunotherapeutic agents
• Documented refractoriness to an obinutuzumab-containing regimen
• Treatment with standard radiotherapy, any chemotherapeutic agent, or treatment with any other investigational anti-cancer agent, including chimeric antigen receptor therapy (CAR-T) within 4 weeks prior to obinutuzumab infusion
• Prior solid organ transplantation
• Prior allogeneic stem cell transplantation (SCT)
• Autologous SCT within 100 days prior to obinutuzumab infusion
• Participant with history of confirmed progressive multifocal leukoencephalopathy (PML)
• Current or past history of central nervous system (CNS) lymphoma
• Current or past history of CNS disease, such as stroke, epilepsy, CNS vasculitis, or neurodegenerative disease. Participants with a past history of stroke that have not experienced a stroke or transient ischemic attack in the past 2 years and have no residual neurologic deficits are allowed
• Evidence of significant, uncontrolled concomitant diseases that could affect compliance with the protocol or interpretation of results, including diabetes mellitus, history of relevant pulmonary disorders and known autoimmune diseases
• Participants with another invasive malignancy in the last 2 years (with the exception of basal cell carcinoma and tumors deemed by the Investigator to be of low likelihood for recurrence)
• Significant or extensive history of cardiovascular disease such as New York Heart Association Class III or IV or Objective Class C or D cardiac disease, myocardial infarction within the last 6 months, unstable arrhythmias, or unstable angina
• Administration of a live, attenuated vaccine within 4 weeks before obinutuzumab infusion or anticipation that such a live attenuated vaccine will be required during the study
• Received systemic immunosuppressive medications (including but not limited to cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-tumor necrosis factor agents) within two weeks prior to obinutuzumab infusion. Treatment with corticosteroid </= 25 mg/day prednisone or equivalent is allowed. Inhaled and topical steroids are permitted
• Any other diseases, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that would contraindicate the use of an investigational drug
• History of autoimmune disease, including but not limited to myocarditis, pneumonitis, myasthenia gravis, myositis, autoimmune hepatitis, systemic lupus, erythematosus, rheumatoid arthritis, inflammatory bowel disease, vascular thrombosis associated with antiphospholipid syndrome, Wegener's granulomatosis, Sjögren's syndrome, Guillain-Barré syndrome, multiple sclerosis, vasculitis, or glomerulonephritis.
