Overview

Aptadel Therapeutics Partnership Grant

Geographic Scope: Barcelona, Spain

Background

This is a follow-up commitment to advance ADEL-101, an aptamer drug conjugate (ApDC) targeting EWSR1::FLI1 (Type 1) fusion in Ewing sarcoma. The initial $500,000 grant supported preclinical development; this additional $680,000 addresses biodistribution challenges identified in mouse models.

Focus Areas

  • Drug: ADEL-101 (aptamer drug conjugate)
  • Target: EWSR1::FLI1 fusion oncogene in Ewing sarcoma
  • Challenge: Previous studies showed rapid kidney clearance; new strategy aims to improve biodistribution by increasing compound size to prevent renal filtering
  • Timeline: 15-month development period to improve in vivo proof-of-principle
  • Goal: Enhanced tumor targeting and therapeutic activity leading to clinical translation

Mechanism of Action

ADEL-101 uses an RNA aptamer that binds to epHA2 (marker on Ewing sarcoma cells) and delivers siRNA to silence the EWSR1::FLI1 fusion gene.
