Summary:
The goal of this research study is to evaluate the combination of study drugs, Glofitamab
and Polatuzumab, and a standard chemotherapy regimen, R-CHP, as a treatment for high-risk
diffuse large B-cell lymphoma.
The names of the treatment interventions involved in this study are:
- Glofitamab (T-cell bispecific antibody)
- Polatuzumab (antibody-drug conjugate)
- R-CHP (a chemotherapy regimen comprised of Rituximab, Cyclophosphamide, Doxorubicin
Hydrochloride, and Prednisone)
Detailed description:
This study is an open-label, multi-center, single-arm phase II study of glofitamab plus
polatuzumab and R-CHP for patients with previously untreated high-risk diffuse large
B-cell lymphoma (DLBCL).
- Study procedures include screening for eligibility, study evaluations, radiological
scans of tumors, tumor biopsies, TTE/MUGA scans, and blood collections.
- All participants will receive two cycles of polatuzumab -R-CHP and four cycles
of glofitamab- polatuzumab -R-CHP. After completion of chemotherapy patients
will receive two additional cycles of glofitamab alone.
- Participants receive study treatment for up to 8 cycles of treatment and will
be followed for 5 years.
- It is expected that about 40 people will take part in this research study.
- This research study is a Phase II clinical trial. Phase II clinical trials test the
safety and effectiveness of an investigational drug to learn whether the drug works
in treating a specific disease. "Investigational" means that the drug is being
studied.
- The U.S. Food and Drug Administration (FDA) has not approved glofitamab as a
treatment for any disease.
- The FDA has approved polatuzumab in combination with rituximab and another
chemotherapy agent, bendamustine, for DLBCL that has already been treated with
two prior treatments, but not as an initial therapy.
- The R-CHP regimen is FDA approved and standard care for cancer treatment.
- Genentech is supporting this research study by providing drug and funding for this
trial.
Criteria for eligibility:
Criteria:
Inclusion Criteria:
- Previously untreated patients with CD20-positive DLBCL, including one of the
following diagnoses by 2016 WHO classification of lymphoid neoplasms
- DLBCL, not otherwise specified (NOS)
- T-cell/histiocyte-rich large B-cell lymphoma
- Epstein-Barr virus-positive DLBCL, NOS
- ALK-positive large B-cell lymphoma
- HHV8-positive DLBCL, NOS
- High-grade B-cell lymphoma (HGBCL), NOS
- HGBCL with translocations of MYC and BCL-2, or MYC and BCL-6
- Availability of archival (within 90 days) or freshly collected tumor tissue before
study enrollment. If archival tissue is unavailable or is determined to be
inadequate, tumor tissue must be obtained from a biopsy performed at screening,
unless an exception is given after consultation with the principal investigator.
- IPI score of 2-5
- ECOG Performance Status of 0, 1, or 2 (see Appendix A)
- Greater than or equal to 18 years at the time of signing informed consent
- Left ventricular ejection fraction (LVEF) ≥ 50% on cardiac multiple-gated
acquisition (MUGA) scan or cardiac echocardiogram (ECHO)
- Adequate hematologic function (unless due to underlying disease, as established for
example, by extensive bone marrow involvement or due to hypersplenism secondary to
the involvement of the spleen by DLBCL per the investigator), defined as follows:
- Hemoglobin ≥ 9.0 g/dL without transfusion for 14 days before first treatment
- ANC ≥ 1,000/μL
- Platelet count ≥ 75,000/μL
- Participants must have adequate organ as defined below:
- Total bilirubin ≤ 1.5 x institutional upper limit of normal (ULN) or < 3 x ULN
in participants with Gilbert's disease
- PT or INR > 1.5 the ULN in the absence of therapeutic anticoagulation or lupus
anticoagulant
- AST(SGOT)/ALT(SGPT) ≤ 2.5 × institutional ULN
- Adequate renal function defined by serum creatinine ≤1.5 x ULN or creatinine
clearance (by Cockcroft-Gault) ≥ 40 ml/min
- At least one bi-dimensionally FDG-avid measurable lymphoma lesion on PET/CT scan,
defined as > 1.5 cm in its longest dimension on CT scan
- Women of childbearing potential (WOCBP) must agree to use effective contraception
when sexually active. Women must remain abstinent or use methods of contraception,
including at least one method with a failure rate of <1% per year, during the
treatment period and for 12 months after the final dose of pola-R-CHP, 2 months
after the last dose of glofitamab, and 9 months after the last dose of polatuzumab
whichever is longer. Examples of contraceptive methods with a failure rate of <1%
per year include bilateral tubal ligation, male sterilization, hormonal
contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and
copper intrauterine devices. A woman is considered of childbearing potential, i.e.
fertile, following menarche and until becoming post-menopausal unless permanently
sterile. Permanent sterilization methods include but are not limited to
hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal
state is defined as no menses for continuous 12 months without an alternative
medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal
range may be used to confirm a post-menopausal state in women not using hormonal
contraception or hormonal replacement therapy. The investigator or a designated
associate is requested to advise the patient how to achieve highly effective birth
control. The use of condoms by male patients is required unless the female partner
is permanently sterile.
- For men: agreement to remain abstinent (refrain from heterosexual intercourse) or
use a condom, and agreement to refrain from donating sperm, as defined below: With
female partners of childbearing potential or pregnant female partners, men must
remain abstinent or use a condom during the treatment period and for 12 months after
the final dose of pola-R-CHP, 2 months after the last dose of glofitamab, and 9
months after the last dose of polatuzumab whichever is longer. Men must refrain from
donating sperm during this same period. The reliability of sexual abstinence should
be evaluated in relation to the duration of the clinical trial and the preferred and
usual lifestyle of the patient. Male patients considering preservation of fertility
should bank sperm before study treatment.
- For participants with evidence of chronic hepatitis B virus (HBV) infection, the HBV
viral load must be undetectable on suppressive therapy, if indicated. Patients must
be willing to have monthly testing and antiviral therapy if indicated. Participants
with a history of hepatitis C virus (HCV) infection must have undetectable viral
load.
- Ability to understand and the willingness to sign a written informed consent
document.
Exclusion Criteria:
- Contraindication to any of the individual components of study drugs, including prior
receipt of anthracyclines, or history of severe allergic or anaphylactic reactions
to humanized or murine monoclonal antibodies, or known sensitivity or allergy to
murine products. Patients with a history of hypersensitivity to dexamethasone or
systemic corticosteroids will also be excluded
- Prior organ transplantation
- History of indolent lymphoma or current diagnosis of the following: follicular
lymphoma grade 3B; B-cell lymphoma, unclassifiable, with features intermediate
between DLBCL and classical Hodgkin lymphoma (grey-zone lymphoma); primary
mediastinal (thymic) large B-cell lymphoma; Burkitt lymphoma; CNS lymphoma (primary
or secondary involvement), primary effusion DLBCL, and primary cutaneous DLBCL

lymphoma symptom control. Patients receiving corticosteroid treatment with ≤ 30
mg/day of prednisone or equivalent for reasons other than lymphoma symptom control
must be documented to be on a stable dose of at least 4 weeks' duration prior to the
start of Cycle 1. Patients who require lymphoma symptom control during screening may
receive steroids in the following manner: Up to 30 mg/day of prednisone or
equivalent may be used for lymphoma symptom control during screening, including
prior to finalization of staging (not included as part of pre-phase treatment). If
glucocorticoid treatment is urgently required at higher doses for lymphoma symptom
control prior to the start of study treatment, tumor assessments must be completed
prior to initiation of > 30 - 100 mg/day of prednisone or equivalent. Prednisone >
30 - 100 mg/day or equivalent may be given for a maximum of 7 days as a pre-phase
treatment. As part of the pre-phase treatment.
