ListOutcomeTime frameDescription
PrimaryNumber of Participants With Serious and Non-serious Adverse EventsDate treatment consent signed until 30 days after removal from study treatment or until off study, whichever comes first, approximately 22 weeks.
Here is the count of participants with serious and non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v3.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.
PrimaryMaximum Tolerated Dose (MTD) of SiplizumabFirst 30 days after treatment initiation.
A classic 3+3 dose-escalation design was used to assess the MTD of siplizumab in combination with dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin and rituximab (EPOCH-R). If 2 of 6 patients experienced a dose-limiting toxicity (DLT) at a particular dose level, the MTD has been exceeded. The preceding dose level will be the MTD, provided 6 patients have been entered at this level and no more than one has experienced a DLT. DLTs for siplizumab was defined as infusional grade 3 non-hematologic toxicity lasting longer than 6 hours after the infusion, any grade 4 non-hematologic toxicity, or the development of an Epstein Barr Virus (EBV)-related lymphoproliferative disorder (LPD). Expected toxicities of dose-adjusted EPOCH-R and grade 3 laboratory adverse events (AEs) were not considered to be DLTs.
SecondaryNumber of Participants With a Response to Therapy
Response assessments were performed after the fourth and sixth cycle of therapy, at therapy completion, and every 3 months for year 1, four months for year 2, 6 months for years 3-5, and annually thereafter, up to 5 years.
Response was assessed by the International Workshop to Standardize Response Criteria for Non-Hodgkin's Lymphoma. Complete Remission was defined as the disappearance of all detectable clinical and radiographic evidence of disease, disappearance of all disease related symptoms if present before therapy, and normalization of those biochemical abnormalities (for example lactate dehydrogenase (LDH)) definitely assignable to the lymphoma. Complete response unconfirmed was defined as a residual node greater than 1.5 cm, with a decrease by greater than 75 percent in the sum of the products of the perpendicular diameters (SPD) of all measured lymph nodes. Partial Response was defined as a ≥ 50% decreased in SPD of 6 largest dominant nodes or nodal masses. Relapsed disease was defined as the appearance of any new lesion or increase by ≥50% in the size of the previously identified sites. Progressive disease was defined as a ≥50% increase from nadir in the SPD.
SecondaryOverall Progression Free Survival (PFS)On-study date until date of progression or last follow up, approximately 7 months.
Progression was assessed by the International Workshop to Standardize Response Criteria for Non-Hodgkin's Lymphoma. Progression is defined as ≥50% increase from nadir in the sum of the products of the perpendicular diameters (SPD) of any previously identified abnormal nodes for Partial Response's or non-responders. Progression-free survival (PFS) was determined from the on-study date until date of progression or last follow-up. The probability of PFS as a function of time was estimated by the Kaplan-Meier method.
SecondaryOverall Survival (OS)On study date until date of death or last follow up, approximately 12 months.Overall survival was determined from the on-study date until date of progression or last follow up. The probability of OS as a function of time was estimated by the Kaplan-Meier method.
OtherNumber of Dose-Limiting Toxicities (DLT)First 30 days after treatment initiation.
DLTs for siplizumab was defined as infusional grade 3 non-hematologic toxicity lasting longer than 6 hours after the infusion, any grade 4 non-hematologic toxicity, or the development of an EBV-related lymphoproliferative disorder (LPD). Expected toxicities of dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin and rituximab (EPOCH-R) and grade 3 laboratory AEs were not considered to be DLTs.
