Perhaps you were thinking of Pharming's recombinant human C1 inhibitor.
No, I wasn’t thinking of Pharming’s Rhucin, which is not directly comparable to Berinert and Cinryze due to its much shorter half-life (#msg-29201262). Rather, I must have been thinking of the statement by Lev’s CEO on one of the company’s earliest CC’s in 2007 that the company intended to develop a recombinant C1 inhibitor.
