Retrophin, Inc. (NASDAQ:RTRX) today reported its financial results for the quarter ended March 31, 2014.

"The first quarter of 2014 was a transformative period for Retrophin," said Martin Shkreli, Founder and Chief Executive Officer of Retrophin. "We listed our stock on the NASDAQ and completed a successful public offering in January. In March, we acquired Manchester Pharmaceuticals and became a commercial company with two FDA-approved products. The robust reimbursement of Chenodal and our initial efforts to identify undiagnosed cerebrotendinous xanthomatosis, or CTX, patients have been especially encouraging. We are raising our revenue guidance to reflect this positive operating momentum."

He added, "We continue to aggressively pursue product acquisition candidates, and our list of attractive targets and access to capital remain robust. We also look forward to continuing to advance our pipeline as we work toward bringing these promising therapies to patients with catastrophic diseases who desperately need treatment options."
