Show all 16Show fewer
- All patients must be stable without any signs of active infection, systemic (oral or parenteral) corticosteroid or anticonvulsant therapy for at least 2 weeks prior to study treatment. Inhaled non-absorbable and topical corticosteroid use are permitted as indicated.
- Eastern Cooperative Oncology Group (ECOG) performance status 0 to 1 with no deterioration over the previous 2 weeks.
- Women of child-bearing potential and male subjects shall agree to take medically acceptable contraception measures while on study treatment and for 3 months following completion of study treatment. All women of child-bearing potential must have a negative blood pregnancy test at screening.
- Women must remain abstinent or use contraceptive methods with a failure rate of ≤1% per year during the study treatment period and for 2 months after the final dose of glofitamab, 3 months after the final dose of tocilizumab (if applicable), 12 months after rituximab or chemotherapy, or 18 months after the final dose of obinutuzumab. Women must refrain from donating eggs during this same period. A woman is considered of childbearing potential if she is postmenarchal, has not reached a postmenopausal state (≥12 continuous months of amenorrhea with no identified cause other than menopause), and is not permanently infertile due to surgery (i.e., removal of ovaries, fallopian tubes, and/or uterus) or another cause as determined by the investigator (i.e., Müllerian agenesis). The definition of childbearing potential may be adapted for alignment with local guidelines or regulations. Examples of contraceptive methods with a failure rate of ≤1% per year include bilateral tubal ligation, male sterilization, hormone-releasing intrauterine devices, and copper intrauterine devices. Hormonal contraceptive methods must be supplemented by a barrier method. 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 individual. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or post ovulation methods) and withdrawal are not adequate methods of contraception. If required per local guidelines or regulations, locally recognized adequate methods of contraception and information about the reliability of abstinence will be described in the local Informed Consent Form. For men who are not surgically sterile (or with azoospermia for other reasons): Investigators will discuss sperm conservation prior to initiation of study treatment for male participants. Participants who agree to remain abstinent (refrain from heterosexual intercourse) or use contraception, and agree to refrain from donating sperm, as defined below: With a female partner of childbearing potential who is not pregnant, men 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 study treatment period and for 2 months after the final dose of glofitamab, 3 months after the final dose of tocilizumab (if applicable), 6 months after rituximab, ICE (ifosfamide, carboplatin, and etoposide) or obinutuzumab. 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 individual. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or post ovulation methods) and withdrawal are not adequate methods of contraception. If required per local guidelines or regulations, locally recognized adequate methods of contraception and information about the reliability of abstinence will be described in the local Informed Consent Form.

About this study
Official title: A Phase II,Open Label, Single Arm, Multicenter Study Investigating the Efficacy and Safety of Glofitamab When Used as a Bridge to and/or Consolidation Post-transplant for Patients With Relapsed/Refractory B-cell Lymphomas Transformed Low Grade B Cell Lymphoma) Fit and Eligible for ASCT
This is an investigator-initiated, open-label, single-arm, multicenter, Phase II clinical study. The study is designed to evaluate the safety and potential effectiveness of glofitamab in adults with their disease, diffuse large B-cell lymphoma (DLBCL has either not responded to initial treatment or has returned after an initial response and who are eligible and medically fit for autologous stem cell transplantation (ASCT). Autologous stem cell transplantation is a commonly used treatment in this situation and involves high-dose chemotherapy followed by infusion of your own stem cells, which are collected from your blood several weeks before the transplant.
The purpose of this study is to assess glofitamab, which is not part of standard treatment. Glofitamab is a type of antibody designed to attach to both lymphoma cells and certain immune cells called T cells. By bringing these cells together, glofitamab may help activate the immune system so that T cells can better recognize and destroy lymphoma cells. In this study, glofitamab may be used as a "bridge" to transplantation and/or as consolidation treatment after the transplant, depending on how the disease responds to chemotherapy given before the transplant.
In recent years, newer immune-based treatments such as CAR-T cell therapy have shown benefit for patients whose lymphoma does not respond to or returns after chemotherapy. CAR-T therapy involves collecting immune cells, modifying them in a laboratory, and then reinfusing them into the patient. However, access to CAR-T therapy is limited in some regions, including Lebanon, and autologous stem cell transplantation remains an important treatment option

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
GlofitamabDrug
Glofitamab is started with initially a step-up dosing of 2.5 mg on C1D1 then 10 mg on C1D8 to be followed by 30 mg every 3 weeks for a total of 3 cycles. Disease evaluation is repeated after completion of 3 cycles of Glofitamab, and patients achieving PR or better then undergo ASCT followed by 3 cycles post consolidation glofitamab (30 mg every 3 weeks).
| Study group | Role | What they receive |
|---|---|---|
| single arm study assessing the efficacy and safety of Glofitamab as a bridge to and/or consolidation | Experimental | Participants who complete two cycles of Rituximab-chemotherapy will undergo evaluation by PET scan.
* Complete responders will proceed to a third cycle of Rituximab-chemotherapy, followed by autologous stem cell transplantation (ASCT) and six cycles of consolidation Glofitamab.
* Participants with an incomplete response will receive three cycles of salvage Glofitamab, after which they will be re-evaluated by PET scan. Patients achieving a complete response at this stage will proceed to ASCT, followed by three cycles of consolidation Glofitamab. Non-responders will be discontinued from the study Receives: Drug: Glofitamab |
What is being measured
The primary outcome is the main question the study is designed to answer.
To evaluate the efficacy of glofitamab when used as a bridge to and/or consolidation post-transplant for patients with relapsed/refractory B-cell lymphomas (DLBCL or transformed low grade B cell lymphoma) fit and eligible for ASCT
Progression free survival (PFS) at 1 year post relapse-defined as the time from infusion of first salvage chemotherapy to the first occurrence of disease progression or death from any cause, whichever occurs first as determined by the investigator
Measured: 3 years
Secondary outcomes (8)
To evaluate the 3 years overall survival
Overall survival (OS) at 3 year post relapse defined as the time from first dose of salvage chemotherapy to date of death from any cause
Measured: 3 years
To evaluate the safety and tolerability of glofitamab in this setting
Incidence and severity of adverse events (AEs), with severity determined according to the national Cancer Institute Common Toxicity Criteria for Adverse Events, Version 5.0 (NCI CTCAE v5.0)
Measured: 3 years
To evaluate the effect of glofitamab when used as a bridge to and/or consolidation post ASCT on health-related quality of life (HRQoL)
Changes in QLQ-NHL-HG29 questionnaire results taken before first dose of glofitamab and that taken at end of treatment with glofitamab.
he EORTC QLQ-NHL-HG29 (European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - Non-Hodgkin Lymphoma-High-Grade 29) is a disease-specific quality-of-life instrument. Scores are transformed to a 0-100 scale. For functional domains, higher scores indicate better outcomes, whereas for symptom domains, higher scores indicate worse outcomes.
Measured: 3 years
To evaluate the effect of treatment with glofitamab on acute phase reactants such as fibrinogen and its clinical significance
Changes in fibrinogen level from baseline (before starting first dose of glofitamab compared to post each dose of glofitamab and post last dose of glofitamab) will be correlated with PFS and CRS.
Measured: 1 year
To Assess the complete response rate
the complete response (CR) defined as the proportion of patients whose best overall response is CR on positron emission tomography (PET/CT scan) at two time points (at transplant for those receiving glofitamab as a bridge to ASCT, and at end of treatment (EOT) with glofitamab (3-4 weeks after last dose of post-ASCT consolidation with glofitamab) for all patients
Measured: 1 year
To Assess the rate of ASCT
the rate of ASCT is assessed after induction chemotherapy and after 3 doses of Glofitamab for non- responders.
Rate of ASCT for those receiving Glofitamab as salvage therapy is assessed post induction chemo and post 3 dose Glofitamab for non resposnders.
Measured: 1 year
clinical complete response rate
Rate of complete response (CR) defined as the proportion of patients whose best overall response is CR on positron emission tomography (PET/CT scan) at two time points (at transplant for those receiving glofitamab as a bridge to ASCT, and at end of treatment (EOT) with glofitamab (3-4 weeks after last dose of post-ASCT consolidation with glofitamab) for all patients
Measured: 6 months
Rate of ASCT for patients receiving glofitamab as salvage therapy
The rate of autologous stem cells transplantation of patients who received salvage Glofitamab is defined as the proportion of patients who reached the ASCT after completing the salvage Glofitamab treatment after being evaluated by PET scan and Bone Marrow aspirate and biopsy to confirm complete response rate.
Measured: 6 months
