biosimilar
n.— «The so-called generic versions of biotechnology drugs could never be exact copies. At most, they could be highly similar, which is why the industry avoids the “generic” term and refers to them as “biosimilars” or “follow-on biologics.”» —“Cheaper biotech drugs?” by Terri Somers Union-Tribune (San Diego, California) July 13, 2007.
