Biogen Idec and Stromedix, Inc. today announced that they have entered into a definitive agreement under which Biogen Idec will acquire Stromedix Inc., a privately held biotechnology company focused on innovative therapies for fibrosis and organ failure. Under the terms of the agreement, Biogen Idec will make an upfront cash payment of $75 million and additional contingent value payments of up to $487.5 million based on the achievement of certain development and approval milestones across multiple indications.
Stromedix’s lead candidate, STX-100, is a novel humanized monoclonal antibody that selectively disrupts the TGF-beta pathway, which plays a central role in fibrotic disease. STX-100 exhibited significant anti-fibrotic activity in preclinical animal models of fibrotic disease and demonstrated an attractive safety and tolerability profile in a Phase 1 trial. Stromedix has also identified a series of clinical biomarkers that reflects the biological activity of STX-100. STX-100 is entering a Phase 2 trial in patients with idiopathic pulmonary fibrosis (IPF), a debilitating and almost uniformly fatal disease in which patients experience progressive difficulty breathing due to fibrosis (scarring) of the lung. More than 200,000 patients in the United States and Europe have IPF, and there is no FDA-approved treatment for the disease at this time. STX-100 has potential in several additional fibrotic indications given its selective mechanism of action. In addition to STX-100, Stromedix has a preclinical compound that may have utility for the treatment of injury due to inflammation.
“Fibrotic organ failure, and in particular IPF, is a terrible disease with a high mortality rate, and there are no effective treatments at this time,” said Douglas E. Williams, EVP, R&D of Biogen Idec. “We believe STX-100 has the potential to be a best-in-class therapy and it is an excellent strategic fit with our focus on highly differentiated programs with the potential to make a real difference for patients. The Phase 2 program complements our scientific expertise and advances our research and development efforts in immunology. We are pleased to welcome Mike and his team back to Biogen Idec to drive STX-100’s continued development. Their work in advancing STX-100 through Phase 1 and developing biomarkers to inform upcoming clinical trials increases the likelihood of bringing a much-needed therapy to patients. This acquisition brings together our scientific strengths and capabilities with a clear goal of providing highly effective therapies to patients suffering from fibrosis.”
“With a well-established understanding of the fundamental biology and tremendous unmet medical need, fibrosis is one of the most exciting and dynamic areas of drug development today,” said Michael Gilman, Ph.D., Founder and CEO of Stromedix, who, before founding Stromedix, led Biogen Idec’s research organization from 2000 to 2005. “We appreciate Biogen Idec’s focus in immunology and their tremendous international R&D and commercial capabilities. By joining forces, we expect to accelerate the development of STX-100 and other promising early-stage drug candidates. This begins a new chapter for all of us at Stromedix, and we look forward to a bright future as part of Biogen Idec.”
