Study Endpoints

Primary Endpoints

Complete response rate
3 months after starting therapy

• Complete response (CR) rate after 4 cycles of TPG therapy, evaluated by PET-CT using Lugano criteria

Rate of toxicities
From the day when informed consent is obtained until 90 days following the last administration of study treatment.

Occurrence and severity of adverse events will be examined throughout the treatment using the Common Terminology Criteria for Adverse Events (CTCAE) v6.0, except cytokine release syndrome (CRS) and immune cell-associated neurotoxicity syndrome (ICANS) will be assessed using the American Society of Transplantation and Cellular Therapy (ASTCT) criteria

Secondary Endpoints

Progression-free survival
PFS will be measured from the day of the registration on study until the end of follow up, for up to 5 years
Event-free survival
EFS will be measured from the day of the registration on study until the end of follow up, for up to 5 years
Overall survival
OS will be measured from the day of the registration on study until the end of follow up, for up to 5 years

Treatment Arms

ArmTypeDescription
TPG therapyEXPERIMENTALAll enrolled patients will receive the same study therapy for the first four 21-day cycles, followed by the primary endpoint evaluation, and subsequent response-adapted therapy. After 4 cycles, the primary endpoint will be assessed by using positron emission tomography/computed tomography (PET-CT) based Lugano criteria. Subsequent therapy will be determined at that time, guided by the response assessment. Patients in complete response or with a partial metabolic response and a negative minimal residual disease (MRD) assay will continue with subsequent cycles of TPG immunotherapy. Patients who do not achieve these criteria will transition to standard immunochemotherapy, which will be delivered according to institutional standards.
