Piper Jaffray analyst Edward Tenthoff recommends buying shares of Vertex Pharmaceuticals following yesterday's selloff. Biotech names pulled back after Presidential candidate Hillary Clinton announced her intention to reveal a drug pricing plan to prevent "gouging," Tenthoff tells investors in a research note. He believes, however, that drugs like Vertex's Orkambi will maintain premium pricing because of the disease modifying value to patients and payors. Orkambi is approved to treat cystic fibrosis in patients 12 years and older. The analyst reiterates an Overweight rating on Vertex with a $163 price target. The stock closed yesterday down $5.97 to $118.19.

Vertex Pharmaceuticals announced that the European Commission has granted approval for the label expansion of KALYDECO for the treatment of infants down to 1 month of age with cystic fibrosis who have one of the following mutations in the cystic fibrosis transmembrane conductance regulator gene: R117H, G551D, G1244E, G1349D, G178R, G551S, S1251N, S1255P, S549N or S549R. As a result of existing access agreements in Austria, Czech Republic, Denmark, Ireland, Norway, Sweden, and The Netherlands, eligible patients will have access to the expanded indication of KALYDECO shortly following regulatory approval by the European Commission. Vertex will continue to work with reimbursement authorities across the European Union to ensure access for all other eligible patients. In the U.K., following MHRA approval at the end of 2023, and as a result of the existing reimbursement agreement between Vertex and the National Health Service, eligible infants ages 1 month and older in the U.K. have access to this expanded indication for KALYDECO.
