Summary

Study Title: Phase I/II study of brentuximab vedotin and methotrexate/ L-asparaginase/ dexamethasone (B-MAD) chemotherapy in patients with newly-diagnosed Extranodal NK/T-cell Lymphoma

Phase: I/II

Number of Patients: 36

Study Objectives

Primary

  • To determine the safety and optimal dose of brentuximab vedotin when use in combination with methotrexate, L-asparaginase and dexamethasone in the treatment of newly-diagnosed ENKTL patients

Secondary

  • To evaluate the clinical efficacy of this regimen
  • To access the overall responses including overall response rate (ORR), disease-free survival (DSF), progression-free survival (PFS).

Overview of Study Design:

Open-label, multicenter, non-randomized, 3+3 dose escalation study of brentuximab vedotin in combination with fixed-dose MAD chemotherapy. The first cycle will be evaluated for the determination of the recommended phase II dose.

Patients will be received the treatment according to the stage of disease as follows:

  • Patients with localized ENKTL (stage IE or stage IIE) will receive involved-field radiation (IRFT) with concomitant weekly intravenous Cisplatin. Three to five weeks after the completion of IFRT and cisplatin, B-MAD (Brentuximab vedotin, Methotrexate, L-asparaginase and Dexamethasone) regimen will be given every 21 days for 3 cycles.
  • Patients with advanced ENKTL (stage III or stag IV) will receive B-MAD every 21 days for 6 cycles.

Study Population:

Patients with newly-diagnosed ENKTL will be screened for enrollment.

Duration of Study: 3 years

Overview of Study Design:

Open-label, multicenter, non-randomized, 3+3 dose escalation study, starting with 1.2 mg/kg brentuximab vedotin i.v. on day 1 of a 21-day cycle in combination with fixed-dose MAD (Methotrexate, L-asparaginase and Dexamethasone) chemotherapy. The first cycle will be evaluated for the determination of the recommended phase II dose.

Patients will be received the treatment according to the stage of disease as follows:

  • Patients with localized ENKTL (stage IE or stage IIE) will receive involved-field radiation (IRFT) 40-50 Gy with concomitant weekly intravenous Cisplatin. Three to five weeks after the completion of IFRT and cisplatin, B-MAD chemotherapy will be given every 21 days for 3 cycles.
  • Patients with advanced ENKTL (stage III or stag IV) will receive B-MAD every 21 days for 6 cycles.

Study Population:

Patients with newly-diagnosed ENKTL will be screened for enrollment.

Duration of Study: 3 years

Determination of Sample Size

ENKTL is a rare and highly aggressive disease. Due to the rarity, most published studies evaluating new treatment regimen for ENKTL enrolled approximately 20-40 patients in their studies. Since the phase I of this study is designed as 3+3 dose escalation, then this study will enroll approximately 3-12 patients with localized stage in phase I for dose finding. The beginning dose of brentuximab vedotin will be 1.2 mg/kg, escalating gradually until dose limiting toxicity (DLT) is observed. Initially, 3 patients will be treated with 1.2 mg/kg of brentuximab vedotin and will be monitored for DLT. If there is no DLT observed in all 3 patients at the end of their first treatment cycle, dose escalation to the next dose level (1.8mg/kg) may commence. If there is a DLT observed in 1 of the first 3 patients, additional 3 patients will be included, expanding the cohort to 6 patients. This cohort of patients will be treated with the same previous dose of 1.2 mg/kg and monitor for DLTs. If no DLT observed, dose escalation to the next level (1.8 mg/kg) may commence. If there are DLTs observed in 2 or higher in any of the 6 patients prior dose (0.8mg/kg) will be defined as MTD. There will be no further additional patient inclusion and dose escalation beyond the maximum number of 12 patients and 1.8mg/kg, as MTD will be exceeded.

For phase II study, after reviewed the number of ENKTL patients in the Thai Lymphoma Study Group Registry, there were 106 newly diagnosed ENKTL patients in the registry from 2007-2013. This translated to approximately 15 newly diagnosed ENKTL patients per year. Since this study has the time for patient accruement of three years and with respect to the reference from other previous studies, the total approximate patients in this study for phase I and II is 36.

Populations for Analyses

The full analysis set (FAS) comprises of all patients who were enrolled into the study.

The per-protocol analysis (PAS) set comprises of all patient in the FAS who completed cycles of B-MAD.

The dose-determining set (DDS) comprises of all patients in the SAS who had at least one valid safety assessment after completion of the first cycle of B-MAD or discontinue earlier due to DLT.

Demographic and Baseline Characteristics

Demographic and baseline characteristics will be listed individually by patient, and summarized by cohort using descriptive statistic. The FAS will be used.

Efficacy Analysis

The efficacy analysis set (EAS) comprises of all patients who are able to evaluate for efficacy at least once post-baseline.

Safety Analysis

The safety analysis set (SAS) comprises of all patients of the FAS who received at least one dose of B-MAD and had at least one valid post-baseline safety assessment. (The statement that a patient had no adverse events on the CRF confirms a valid safety assessment.
