Brentuximab Vedotin for Relapsed/Refractory CD30-positive Non-Hodgkin Lymphomas

NCT02280785

Description:

Brentuximab vedotin is an antibody-drug conjugate targeting CD30, one of surface antigens expressed in lymphoma cells. Fanale MA, et al. reported the results of a phase I study with weekly dosing of brentuximab vedotin in patients with relapsed/refractory CD30-positive hematologic malignancies (Clin Cancer Res. 2012) showed tumor regression in 85% of patients. Thus, the overall objective response rate was 59% (24/44) including 34% (n = 14) of complete remissions. This study mainly included Hodgkin lymphoma (n = 38) and anaplastic large cell lymphoma (n = 5). However, its efficacy in other types of NHL has never been reported although this study enrolled one patient with peripheral T-cell lymphoma not otherwise specified (PTCL-NOS). CD30 (TNFRSF8) is a transmembrane glycoprotein of the tumor necrosis factor receptor (TNFR) superfamily, and it is involved in signal transduction via the activation of the NF-κB pathway and the mitogen-activated protein kinases (MAPKs), ultimately modulating cell growth, proliferation and apoptosis. CD30 is a non-lineage-specific activation marker expressed by scattered B and T immunoblasts. In addition, a subset of cases in virtually all T-cell lymphoma entities may also express CD30 but at variable and generally lower levels. In fact, a recent study in 22 patients with extranodal NK/T-cell lymphoma showed 75% of positive rate of CD30 expression (75%). Moreover, CD30 expression was also documented in the tumor sample of EB virus positive diffuse large B-cell lymphomas (EBV + DLBCL) of the elderly (28.9%, 11/38). Therefore, Brentuximab vedotin may have potential benefits for patients with CD30-positive NHL other than anaplastic large cell lymphoma such as CD30-positive PTCLs, NOS. Considering the role of CD30 in signal transduction pathway associated with tumor growth and proliferation, its expression may be associated with tumor aggressiveness. In accordance with this, it is more likely that relapse or refractory NHLs may have CD30 expression, and the potential benefits of this promising agent as a salvage therapy deserve to be further investigated in these patients who have high risk of treatment failure. Thus, we designed a phase II study for relapsed or refractory NHL patients. This study is to explore the safety and activity of dosing once every 3 weeks of Brentuximab vedotin in patients with relapsed or refractory CD30-positive NHL other than anaplastic large cell lymphoma.

Detailed Description

      The principal investigator use a Simon two-stage minimax design based on overall response
      rates. Overall disease control rates will be calculated as the percent of patients that have
      confirmed complete response (CR) or partial response (PR) or stable disease (SD) by
      radiographic response including CT and/or PET scans. We assume a P0 as 20%, and designate a
      target rate (P1) as 40%. Under the error probabilities (α=0.05, β=0.20), eighteen patients
      will be enrolled in the first stage. If overall disease control rate is ≤ 4/18 in the first
      stage, this study will be stopped. If not, this study will recruit patients up to 33
      considering 20% of drop out rate.

      Intent-to-treat analysis will be applied to all primary and secondary efficacy endpoints.
      Response rate will be analyzed based on the response criteria according to Cheson 2007
      (Cheson BD, et al. J Clin Oncol 2007; 25 (5):579-586), and data related to overall response
      rate will be analyzed by statistical analysis including Chi test to evaluate predictive
      factors for response to study drug.

      Overall rate of disease control : CR, PR and SD Progression-free survival : Time between the
      date of treatment start and the date of death due to any cause or date of disease progression
      (Up to 36months) Data related to survival rate for all patients will be analyzed based on
      log-rank test by the Kaplan-Meier method.

Brentuximab vedotinExperimentalBrentuximab vedotin administered in 250ml of 0.9% saline by intravenous infusion over 30 minutes once every 3 weeks. In the absence of infusion toxicities, the infusion rate for all patients must be calculated in order to achieve a 30-minute (approximate) infusion period. Brentuximab Vedotin is dosed at 1.8mg/kg (capped at 100kg of body weight). Dosing is based on patients' weight according to the institutional standard; however, doses will be adjusted for patients who experience a ≥ 10% change in weight from baseline. Actual weight will be used except for patients weighing greater than 100 kg; dose will be calculated based on 100 kg for these individuals. The dose will be rounded to the nearest whole number of milligrams.
