Brentuximab Vedotin and Lenalidomide in Patients With Relapsed/ Refractory T-cell Lymphoma or Hodgkin Lymphoma

Overview

This study is investigating the combination of Brentuximab vedotin and lenalidomide in the treatment of relapsed/refractory peripheral T cell lymphoma or cutaneous T cell lymphoma or Hodgkin lymphoma.

It is hypothesised that lenalidomide may augment the actions of Brentuximab vedotin in these patient groups. The primary objective of the study is to determine the maximum tolerated dose of the combination treatment, which can be used in subsequent studies. The study will also investigate disease response and survival.

Participants will receive Brentuximab vedotin (once every 21 days i.e. 1 cycle) and lenalidomide (daily from day 1 -14 of each cycle) for a maximum of 48 weeks and will be followed for a subsequent 6 months after the end of treatment.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: N/A
    • Intervention Model: Single Group Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: May 15, 2021

Interventions

  • Drug: Lenalidomide 15mg
    • At commencement of study : Lenalidomide will commence at 15 mg daily for days 1-14 of each cycle. Maximum number of cycles = 16. This is a dose finding study so doses will be adjusted depending on toxicity assessment over the course of the study. Dose may vary from 5 mg -25 mg daily depending on dose escalation results and recommendation of safety committee
  • Drug: Brentuximab Vedotin 1.8 mg/Kg
    • At commencement of study : Brentuximab vedotin 1.8mg/kg IV on day 1, repeated every 21 days. Maximum number of cycles = 16. This is a dose finding study so doses will be adjusted depending on toxicity assessment over the course of the study. Dose may be either 1.2 mg/Kg q21 days or 1.8 mg/kg q21 days depending on dose escalation results and recommendation of safety committee

Arms, Groups and Cohorts

  • Experimental: Lenalidomide & brentuximab vedotin
    • Brentuximab vedotin 1.8mg/Kg Lenalidomide 15 mg

Clinical Trial Outcome Measures

Primary Measures

  • Determination of the maximum tolerated dose (MTD), dose-limiting toxicities (DLTs), and recommended phase 2 dose (RP2D) of the combination of lenalidomide and brentuximab vedotin
    • Time Frame: 70 weeks
    • Maximum tolerated dose, dose-limiting toxicities of the combination therapy, and recommended phase 2 dose, in patients with relapsed/refractory cutaneous T-cell lymphoma, CD30-positive Hodgkin lymphoma and CD30-positive peripheral T-cell lymphoma. The MTD is defined as the highest dose level at which the incidence of DLT was less than 33%.

Secondary Measures

  • Safety profile of the combination of lenalidomide and brentuximab vedotin
    • Time Frame: 70 weeks
    • Toxicities measured using CTCAE V4.03.
  • Treatment intensity.
    • Time Frame: 48 weeks
    • Treatment intensity defined as the actual total dose received divided by the actual treatment period.
  • Objective response rate
    • Time Frame: 70 weeks
    • Objective response, defined as achieving either complete response (CR) or partial response (PR) at some stage from time of commencement of treatment until conclusion of period of follow-up (maximum 16 cycles of treatment followed by 6 months of follow-up), or until time of documented progressive disease (defined as clinical and/or radiologic progression).
  • Cytostatic response.
    • Time Frame: 70 weeks
    • Cytostatic response, defined as achieving complete response (CR), partial response (PR) or stable disease (SD) lasting >6 months from time of commencement of treatment until progressive disease (PD).
  • Event free survival.
    • Time Frame: 70 weeks
    • Event free survival (EFS), defined as the time from commencement of treatment to date of early discontinuation of treatment due to toxicity, date of documented disease progression at any site, or date of death from any cause, whichever occurs first.
  • Overall survival
    • Time Frame: 70 weeks
    • Overall survival (OS), defined as the time from commencement of treatment to the date of death from any cause.

Participating in This Clinical Trial

Inclusion Criteria

1. Male or female patients of 18 years or older.

2. Patient must have a diagnosis of a CD30+ Hodgkin Lymphoma or CD30+ peripheral T-cell lymphoma. Patients with either Hodgkin lymphoma or T-cell lymphoma must have expression of CD30 in ≥10% of lymphoma cells. Patients with CTCL will be considered for inclusion even if CD30 immunohistochemical staining with BerH2 antibody is low or negligible (<10%).

1. Peripheral T-cell lymphoma: patients must be considered relapsed or refractory after at least one prior chemotherapeutic regimen or be considered by the investigator to be not suitable for chemotherapy

2. Cutaneous T-cell lymphoma: patients must be relapsed or refractory to one prior systemic therapy or be considered by the investigator to be not suitable for chemotherapy

3. Patients with Hodgkin lymphoma and one of the following:

i. Relapsed or refractory after at least 2 prior chemotherapy-containing regimens ii.Considered unsuitable for chemotherapy

3. Voluntary written informed consent must be given before performance of any study related procedure.

4. Female patient is either post-menopausal for at least 1 year before the screening visit or surgically sterile or if of childbearing potential, agree to practice 2 effective methods of contraception, at the same time, from the time of signing the informed consent through 6 months after the last dose of study drug, or agrees to completely abstain from heterosexual intercourse.

5. Male patients, even if surgically sterilized, (i.e., status post vasectomy) agree to practice effective barrier contraception during the entire study period and through 6 months after the last dose of study drug, or agrees to completely abstain from heterosexual intercourse.
