H.C. Wainwright analyst Andrew Fein downgraded Vertex Pharmaceuticals to Neutral saying the company "may have done too little too late in order to transform its early Kalydeco success into a multimodal CF hegemony." The company is no longer well positioned to remain the leader in the cystic fibrosis space, Fein tells investors in a research note. He cut his price target for the shares to $85 from $155.

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.
