The company announced earlier this summer that it has entered into an agreement to acquire Spitfire Pharma, Inc. (Spitfire) including its product candidate SP-1373 (to be renamed ALT-801), a potent GLP-1/Glucagon receptor co-agonist for the treatment of non-alcoholic steatohepatitis (NASH).

Spitfire, a portfolio company of Presidio Partners, was founded by John J. Nestor, Jr., Ph.D. and Velocity Pharmaceutical Development, LLC, for the sole purpose of developing the NASH drug candidate, SP-1373.

“NASH is a significant unmet need. There are no approved treatments available, and prevalence is growing worldwide as a consequence of an expanding obesity epidemic. Compelling preclinical data generated by Spitfire suggests that ALT-801 could reverse obesity, a primary cause of NASH, thereby reducing excess liver fat, inflammation and fibrosis associated with the disease” said Dr. Vipin K. Garg, Ph.D., President and Chief Executive Officer of Altimmune. “The addition of this exciting product candidate to our portfolio is a transformative transaction for Altimmune.”

An upfront payment of $5 million

Spitfire shareholders will receive an upfront payment of $5 million in Altimmune common stock and will be eligible to receive an additional $8 million in future regulatory and clinical milestones payable in cash or common stock. Spitfire shareholders are also eligible to receive up to $80 million in sales-based milestones. The issuance of common stock to satisfy the milestone payments is subject to stockholder approval in accordance with Nasdaq rules.

ALT-801

ALT-801 builds on the company’s liver disease expertise being developed in Altimmune’s HepTcell program for treating chronic hepatitis B and continues to build and leverage the Company’s deep knowledge of developing novel peptide-based therapeutics.
