An Open-Label Phase lB/II Study of Glofitamab and Atezolizumab or Polatuzumab Vedotin in Adult Patients With Relapsed/Refractory B-Cell Non-Hodgkin's Lymphoma

Belgium, Denmark, Israel211 participantsStarted 2018-05-08

Plain-language summary

This is an open-label, single arm, multicenter, dose finding, Phase Ib study in order to assess the maximum tolerated dose (MTD) and/or recommended Phase II dose (RP2D) for this combination treatment and to evaluate the general safety, tolerability, pharmacokinetic (PK), pharmacodynamic, and preliminary anti-tumor activity of this combination treatment in adult patients. This study includes an additional open-label imaging feasibility sub-study using a tracer in adult participants with relpased/refractory B-cell non-Hodgkin's lymphoma to image CD8+T-cells at baseline and after treatment with glofitamab, including pre-treatment with obinutuzumab.

Main Inclusion Criteria * Histologically-confirmed hematologic malignancy that is expected to express CD20 (Relapsed after or refractory to respond to at least one prior treatment regimen; no available treatment options that are expected to prolong survival or patients refusing chemotherapy or autologous stem cell transplant (SCT)) * Dose-escalation: Grades 1-3b relapsed or refractory (R/R) follicular lymphoma (FL) or marginal zone lymphoma (MZL) (nodal; extra-nodal; or splenic), diffuse large B-cell lymphoma (DLBCL), primary mediastinal large B-cell lymphoma (PMBCL), high-grade B-cell lymphoma (HGBCL) with MYC and BCL2 and/or BCL6 rearrangements (double-hit lymphoma), HGBCL not otherwise specified (NOS), DLBCL arising from FL (transformed FL) * Dose-expansion: R/R LBCL, including DLBCL NOS, DLBCL arising from FL (transformed FL), PMBCL, HGBCL with MYC and BCL2 and/or BCL6 rearrangements (i.e., double-hit and triple-hit lymphomas), and HGBCL NOS * At least one measurable target lesion * Fresh pre-treatment biopsy, but if this cannot be taken, a previous archived biopsy from metastatic lesion can be taken as replacement if it is not older than 6 months and not confounded by major events (progression, treatment) * Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 * Adequate organ function (liver, hematological, renal) * Negative test results for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) Inclusion Criteria Specif…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Best Objective Response Rate (ORR) as Measured by Independent Review Committee (IRC)

Timeframe: Baseline until the end of treatment (13 to 14 months), then ever 3 months until end of study visit (to occur within 4 weeks of disease progression)

Dose Limiting Toxicities (DLTs)

Timeframe: Atezolizumab Arm: During DLT period of 21 days (or up to 42 days in the case of cycle delay), starting on Day 1, Cycle 2; Polatuzumab Vedotin Arm: During 5-week DLT period starting Cycle 1, Day 8
