TLDR

  • A study evaluated the reliability of CD30 detection by IHC and its relationship with BV efficacy in CD30-positive lymphoma.
  • FCM was found to be a more accurate method for assessing CD30 expression levels.
  • Auranofin and napabucasin were identified as potential synergistic agents to enhance the efficacy of BV.

Abstract

Brentuximab vedotin (BV), a CD30-targeted antibody-drug conjugate, has shown significant efficacy in CD30-positive lymphoma. However, the relationships between CD30 expression levels and BV efficacy remains unclear. In this study, we first evaluated the reliability of CD30 detection by immunohistochemistry (IHC) and found that flow cytometry (FCM) offers higher sensitivity and accuracy in assessing CD30 expression. Therefore, FCM may serve as a more effective method for evaluating CD30 levels. Furthermore, we confirmed a positive correlation between CD30 expression levels and BV efficacy. However, even when BV was applied to tumor cells with 100% CD30 expression, its anti-tumor activity did not reach complete eradication, highlighting the need for synergistic combination therapies. To address this, we conducted high-throughput screening (HTS) and identified auranofin and napabucasin as synergistic agents that enhance the efficacy of BV. These findings not only highlight the advantages of FCM for CD30 detection, but also provide valuable insights into combination strategies to optimize the therapeutic potential of BV.

Overview

  • The study evaluates the reliability of CD30 detection by immunohistochemistry (IHC) and its relationship with Brentuximab vedotin (BV) efficacy in CD30-positive lymphoma.
  • Flow cytometry (FCM) is found to offer higher sensitivity and accuracy in assessing CD30 expression levels.
  • The study aims to identify synergistic combination therapies to enhance the therapeutic potential of BV.

Comparative Analysis & Findings

  • FCM is found to be a more effective method for evaluating CD30 levels compared to IHC.
  • A positive correlation is confirmed between CD30 expression levels and BV efficacy.
  • Even with 100% CD30 expression, BV does not achieve complete eradication, highlighting the need for combination therapies.

Implications and Future Directions

  • FCM can be used as a more accurate method for assessing CD30 expression levels in CD30-positive lymphoma.
  • Combination therapies may be necessary to achieve optimal therapeutic potential of BV.
  • Further research is needed to explore the potential of auranofin and napabucasin as combination therapies with BV.
