A Study of BEBT-908 in Combination With Chemotherapy in Patients With Previously Untreated Peripheral T-Cell Lymphoma (PTCL)

Starting soon · Phase 2

Conditions studied: Previously Untreated Peripheral T-Cell Lymphoma

In brief

The goal of this clinical study is to find the best way to combine the study drug BEBT-908 (ifupinostat hydrochloride for injection) with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) for treating previously untreated peripheral T-cell lymphoma, and to find out whether this best combination is better than standard CHOP treatment alone. The main questions this study will try to answer are: What percentage of participants will respond well to treatment with BEBT-908 plus CHOP? Is BEBT-908 plus CHOP better than standard CHOP treatment? What medical problems will participants have while receiving this combination treatment? This study includes an Exploration Phase and an Expansion Phase. The Exploration Phase has 3 cohorts. All participants receive both BEBT-908 and CHOP, but the dosing arrangements differ across cohorts: the dose of BEBT-908 differs, the sequencing of administration differs, and whether participants continue with CHOP or transition to BEBT-908 depends on their tolerability to CHOP. Eligible participants will receive the combination treatment for their assigned cohort. After that, based on the results from all 3 cohorts in the Exploration Phase, one optimal cohort will be selected to proceed into the Expansion Phase. In the Expansion Phase, eligible participants will be randomly assigned (like flipping a coin) in a 1:1 ratio to either the treatment group, receiving the optimal combination regimen identified in the Exploration Phase, or the control group, receiving 6 cycles of CHOP. This study design will help investigators find the best way to combine BEBT-908 and CHOP for treating previously untreated peripheral T-cell lymphoma, and check whether this optimal combination regimen is better than standard CHOP treatment.

• No prior systemic anti-PTCL therapy.
• Life expectancy >6 months.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0-2.
• At least one measurable and evaluable tumor lesion (per Lugano 2014 criteria: nodal lesions must have a longest diameter >1.5 cm; extranodal lesions must have a longest diameter >1.0 cm).
• At screening, laboratory parameters must meet the following standards, unless the investigator determines the abnormality is due to lymphoma (with no corrective or supportive treatment for the following parameters within 2 weeks prior to assessment):
• Peripheral Blood: a) Absolute Neutrophil Count (ANC) ≥1.5×10⁹/L (≥1.0×10⁹/L for patients with bone marrow involvement); b) White Blood Cell count (WBC) ≥3.0×10⁹/L (≥2.0×10⁹/L for patients with bone marrow involvement); c) Hemoglobin (HGB) ≥80 g/L; d) Platelet count (PLT) ≥75×10⁹/L (≥50×10⁹/L for patients with bone marrow involvement).

You may not qualify if…

• Participants who meet any of the following exclusion criteria are not eligible for enrollment:
• History or current diagnosis of immune thrombocytopenia, autoimmune hemolytic anemia, aplastic anemia, or other primary or secondary hematologic disorders that may affect bone marrow function, other than the primary malignancy.
• Receipt of transfusion, recombinant human thrombopoietin (rhTPO), erythropoietin (EPO), granulocyte colony-stimulating factor (G-CSF), or similar treatments within 2 weeks prior to the first dose of study drug.
• Active bleeding within 2 months prior to the first dose, or current use of anticoagulant medications (e.g., warfarin, phenprocoumon), or evidence of a clear bleeding tendency as determined by the investigator (e.g., esophageal varices at risk of bleeding, active localized ulcerative lesions, fecal occult blood >2+), except for bleeding attributed by the investigator to lymphoma itself (e.g., gastrointestinal bleeding caused by gastrointestinal lymphoma).
• Participation in another interventional clinical trial within 3 months prior to the first dose.
• PTCL with involvement of special sites such as testis, breast, or ovary; extranodal natural killer/T-cell lymphoma (ENKTL); cutaneous T-cell lymphoma (except subcutaneous panniculitis-like T-cell lymphoma [SPTCL]); or concurrent hemophagocytic lymphohistiocytosis (HLH).
