Achaogen Receives ₤4.1 Million Award from the Wellcome Trust to Advance its Neoglycosides Portfolio

SAN FRANCISCO, CA, January 8, 2009 – Achaogen, an emerging biopharmaceutical company addressing the issue of multi-drug resistant bacterial infections through the discovery and development of innovative broad-spectrum antibiotics, today announced that it has received a £4.1 million Seeding Drug Discovery award from the Wellcome Trust. This award will help support the investigational new drug (IND)-enabling studies and advancement into clinical trials of Achaogen’s portfolio of proprietary neoglycosides for the treatment of Gram-negative bacterial infections. Neoglycosides are Achaogen’s unique, next-generation aminoglycosides, in development to address the growing issue of multi-drug resistance to antibiotic agents.

“The escalation in resistance to even the most advanced antibiotics available today is one of our most concerning healthcare issues worldwide. Our support of Achaogen’s research recognizes the importance the Wellcome Trust places on this area of urgent need, and our commitment to help stop the spread of untreatable bacterial infections - especially Gram-negative infections - through hospitals, nursing homes and the wider community,” said Dr. Ted Bianco, Director of Technology Transfer at the Wellcome Trust.

The Wellcome Trust award supports ongoing preclinical studies of two Achaogen drug candidates: the Company’s lead compound ACHN-490, which has shown promising broad-spectrum activity against Gram-negative bacterial infections, including the highly resistant Enterobacteriaceae; plus a second set of leads with expanded-spectrum activity against multi-drug resistant Acinetobacter baumannii and Pseudomonas aeruginosa. Both new chemical entities are being studied by Achaogen with the expectation of entering an initial product candidate into Phase 1 clinical development in 2009.

Aminoglycosides are a proven class of antibacterials that remain in extensive clinical use, generating over $650 million in sales worldwide. There has not been a new member of this important class approved for decades, however, and the utility of existing drugs is declining rapidly due to the expansion of resistant bacterial strains – one of the most critical and worrisome issues facing healthcare today.

Kevin Judice, Chief Executive Officer and Chief Scientific Officer of Achaogen, said, “We are very pleased to receive this funding award through the Seeding Drug Discovery Initiative of the Wellcome Trust. It is an honor that such a distinguished organization shares our vision and recognizes our potential to positively impact public health in the area of antibiotic resistance. We anticipate leveraging the wealth of experience and support made available to us through the Trust as we advance these compounds toward the clinic.”
