  • Signed Informed Consent Form(s)
  • Ability to comply with all the study-related procedures, in the investigator's judgement
  • Female patients who are not of child bearing potential (i.e., who are postmenopausal or surgically sterile). For male participants: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods, and agree to refrain from donating sperm, as defined below: With a female partner of childbearing potential or pregnant female partners, male participants must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of < 1% per year during the treatment period and for at least 6 months after pretreatment with obinutuzumab, 6 months after the last dose of polatuzumab, 160 days after the last dose of rituximab, 2 months after the final dose of glofitamab or 2 months after the last dose of tocilizumab (as applicable), whichever is longer.

Study groupRoleWhat they receive
Obinutuzumab, Glofitamab and PolatuzumabExperimentalAll patients will receive 2 cycles of glofitamab and polatuzumab followed by an interim PET scan (iPET2). If iPET2 is negative (Deauville score 1-3), patients will receive 4 cycles of glofitamab-polaRminiCHP. If iPET is positive (Deauville score 4,5) with partial response or stable disease, patients will receive 6 cycles of glofitamab-pola-R-miniCHP (polatuzumab will be omitted from last 2 cycles to keep total number of doses at 6 per standard of care)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Glofitamab, Polatuzumab and Rituximab in people with Diffuse Large B Cell Lymphoma (DLBCL) and High Grade B Cell Lymphoma, run by Memorial Sloan Kettering Cancer Center at 8 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 21 inclusion and 29 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 22 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Pallawi Torka, MD (201-775-7808, torkap@mskcc.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

evaluate the complete response rate (CRR) (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jul 2026.
