Brown University has leased 349 Eddy St. for three years to ProThera Biologics, which plans to sublet some of the space to other biotech firms. The deal continues Brown’s vision for the 4,000-square-foot building as a welcoming home for startups.

PROVIDENCE, R.I. [Brown University] — Brown University has leased the 4,000-square-foot building at 349 Eddy St. to ProThera Biologics. The biotech firm said it has letters of intent from two other startups, Ryon Technologies and 3prime Dx, to sublet some of the space during the three-year lease.

ProThera, a company focused “on the critical role and commercial potential of Inter-alpha Inhibitor Proteins for treating acute life-threatening inflammatory diseases,” moved in Feb. 15, said co-founder and CEO Dr. Yow-Pin Lim. He and Douglas C. Hixson, who are both researchers at Brown and at Lifespan, founded the company in 2002.

The new tenants mark a continuation of Brown’s vision for the building, acquired in 2007, of making it a welcoming home for area startups, said John Luipold, Brown’s assistant vice president for real estate.

“Since 2010, Brown has used this building to help early stage start-ups by offering good space at attractive rents,” he said. “We have rented the building to Nabsys and also NuLabel Technologies during their early growth stages. Both companies, founded by Brown grads, outgrew the building and have moved elsewhere in Rhode Island.”
