NEW YORK (TheStreet) -- Shares of Celldex Therapeutics  (CLDX - Get Report) rose 1.94% to $25.21 in afternoon trading Tuesday after the company's drug Rintega received breakthrough therapy designation from the U.S. Food and Drug Administration on Monday.

Celldex designed Rintega, also known as rindopepimut, to treat adults who suffer from EGFRvIII-positive glioblastoma. The FDA granted the priority status to Rinterga after successful phase II studies on the drug.

Celldex CEO Anthony Marucci said in a statement that glioblastoma patients "have extremely limited treatment options, with only three new drugs approved in more than 20 years."

Celldex reported a loss of 36 cents a share, slightly wider than the consensus estimate of a loss of 34 cents a share.
