Dapolsertib

Dapolsertib is a selective, small-molecule dual inhibitor of PIM and FLT3 kinases, two enzymes, that play a significant role in the malignant transformation of hematopoietic cells and lymphomagenesis.

Key highlights

The compound has been discovered by Ryvu and is currently in clinical development in collaboration with the Menarini Group as a therapeutic option for various cancers.

Key facts:

  • Inhibits lymphoma growth, particularly in ABC-DLBCL.
  • Reduces MYC protein levels and MYC-driven gene expression.
  • Synergistic with anti-CD20 monoclonal antibodies.
  • Well tolerated in in vivo studies and in clinical trials with approx 75 patients with AML.

 

Originally discovered by Ryvu, dapolsertib was licensed to Menarini and is currently in clinical development, with Ryvu serving as the formal sponsor, as part of a collaboration to explore its potential as a therapeutic option for various cancers.

Clinical development

Phase I data were generated in AML:
  • H1 2017- H1 2021 Phase I dose escalation and cohort expansion in R/R AML – MTD of 125 mg established
  • H2 2021 – H1 2023 Phase II expansion cohort in IDH+ R/R AML
  • 73 patients dosed across prior studies, including 48 at the R2PD
  • Manageable safety profile
  • No QTc prolongation, no differentiation syndrome, no gastrointestinal tox
  • No hematologic toxicity

 

JASPIS-01, a Phase II study, is investigating dapolsertib in DLBCL
  • Based on strong preclinical evidcence of MEN1703’s activity in lymphoma
  • Phase II study consists of two parts: Part 1 pilot cohorts to establish combination dose and monotherapy ​efficacy followed by Part 2 cohort expansion​
  • Study locations: USA, Europe​
  • Phase II study initiated in March 2025

For Patients and Caregivers

Dapolsertib is now being evaluated in the JASPIS-01 Phase II trial for relapsed/refractory DLBCL, aiming to assess its safety, efficacy, and therapeutic potential as both a monotherapy and in combination with standard treatments.
