Novartis Signs Deal Worth up to $3.2 Billion for Alteogen’s Drug Delivery Technology

The agreement gives Novartis exclusive options to use Alteogen’s enzyme platform for injectable drugs, with payments tied to milestones, sales and royalties.

  • On Wednesday, South Korea's Alteogen Inc. signed an option and licensing agreement with Novartis worth up to $3.22 billion, granting the Swiss drugmaker access to its ALT-B4 technology for developing injectable versions of intravenous drugs.
  • Built on Alteogen's Hybrozyme platform, ALT-B4 enables biologic drugs traditionally administered intravenously to be converted into subcutaneous formulations by temporarily breaking down hyaluronan for faster absorption.
  • The agreement includes option exercise fees, milestone payments, and royalties on future product sales, with Alteogen eligible to receive the full $3.22 billion if all development and commercial milestones are achieved.
  • This Novartis deal marks Alteogen's fourth ALT-B4 licensing agreement this year, reflecting a broader industry trend where drugmakers increasingly develop under-the-skin versions of medicines to replace traditional intravenous infusions.
  • Merck's Keytruda Qlex, which utilizes ALT-B4, received FDA approval last year, providing commercial validation that the technology effectively converts intravenous biologics into subcutaneous injections.
