  • Aileron Therapeutics Closes $40 Million Series D Financing

    Company Developing Novel Class of Stapled Peptide Drugs as Technology Platform for Historically Undruggable Targets

    CAMBRIDGE, Mass. Aileron Therapeutics, a biotechnology company discovering and developing a novel class of therapeutics called Stapled Peptides, announced today it has closed a $40 million Series D financing. The financing was co-led by new investors SR One Ltd., the independent corporate venture fund of GlaxoSmithKline (NYSE: GSKNews), and Excel Medical Fund. The round also included major participation by existing investors: Apple Tree Partners, who is the founding investor of Aileron, and Novartis Venture Fund. Lilly Ventures and Roche Venture Fund also participated in the offering.

    Proceeds from the financing will be used to advance Aileron’s lead Stapled Peptide program toward clinical trials in 2010 and to further advance the Stapled Peptide platform and programs in oncology, immune/inflammation, metabolic disease, and infectious disease. Stapled Peptides are synthetically locked, or ‘stapled’, into an alpha-helical shape to create drug compounds that are uniquely effective for targets that are ‘undruggable’ with currently available drug approaches. In previous financings, Aileron has raised $20 million in funding.

    “We believe that Stapled Peptides could represent a ‘fourth estate’ in therapeutics, emerging as a major class akin to small molecules, antibodies and vaccines,” said Michael Diem, M.D., Partner at SR One. “The strength of the technology and team at Aileron will ultimately lead to a fundamental paradigm shift in how disease is treated and we are thrilled to be a part of Aileron’s future.”

    “We have now demonstrated, in multiple pre-clinical studies, the powerful potential that Stapled Peptides represents in the treatment of cancer, and our progress highlighting the applicability of Stapled Peptides to a wide variety of diseases is what catalyzed the excitement and success of this financing round,” said Joseph A. Yanchik, III, Chief Executive Officer of Aileron Therapeutics. “The timing of the financing round and the caliber of the participants is further validation of the growing belief in the transformative potential of this novel class of therapeutics and the need for breakthrough technology platforms that will offer significant new growth avenues for the pharmaceutical industry.”

    As part of the closing of this financing transaction, Michael Diem, M.D., Partner at SR One, and Enrico Petrillo, M.D., Managing Director of Excel Medical Fund, will join the board of directors of Aileron. They join existing board members, Seth Harrison, M.D., Chairman of Aileron and Managing General Partner of Apple Tree Partners, Campbell Murray, M.D., Managing Director of Novartis Venture Funds, and Joseph A. Yanchik III, CEO of Aileron.

    ”The progress to date of Aileron has been very impressive, with a consistent flow of promising data showing the potential of Stapled Peptides to be effective therapeutics for targets that have been ‘undruggable’ with today’s drug approaches,” said Campbell Murray, M.D. Managing Director of Novartis Venture Funds. “We look forward to working with Aileron and its investors to help fulfill this potential to deliver a new class of therapeutics for a broad range of diseases.”

    ”We are seeing an unprecedented number of high quality companies and feel that Aileron is best in class. With breakthrough technology, a talented management team, a strong investor syndicate, and dominant IP position, Aileron is spawning the next generation of pharmaceuticals, that combine the best attributes of biologics and traditional pharmaceuticals” said Enrico Petrillo, M.D., managing director of Excel Medical Fund.

    “We are very pleased and gratified with the investors that we have been able to attract into this financing round. Through this financing we have established an excellent team of partners with solid platform development and pharmaceutical development credentials that will ensure that Aileron becomes the type of transformative company that we anticipated at the beginning” said Seth Harrison, M.D., Managing General Partner of Apple Tree Partners.

    About Stapled Peptides

    Aileron’s Stapled Peptides are synthetically locked, or ‘stapled’, into an alpha-helical shape with an optimized cross-linking chemistry to mimic the structure found at the interface of many protein-protein interactions. To achieve this, Aileron has deployed a comprehensive cross-linking tool-kit to install single staples, multiple staples and contiguous staples to achieve desired efficacy and pharmacokinetic profiles. The resulting Stapled Peptide drugs are endowed with unique properties, including efficient cell penetration, high affinity binding to large target protein surfaces, and excellent stability and pharmacokinetic properties within the body.

    About Aileron Therapeutics

    Aileron Therapeutics is a biopharmaceutical company that was first funded in 2005 by Apple Tree Partners to develop and advance a completely new therapeutic modality and class of drugs called Stapled Peptides that are based on discoveries made at Harvard University and the Dana-Farber Cancer Institute. Stapled Peptide drugs represent the first general solution for modulating intracellular protein-protein interactions, which have been identified as critical control points for most human diseases. As such, Stapled Peptide drugs offer a unique opportunity to exploit potentially thousands of currently “undruggable” targets across all human diseases. Aileron is building a robust pipeline of therapeutics for the treatment of cancer, infectious disease, metabolic disease and immune/inflammatory diseases.
