Here’s What’s Driving Up Proteon Therapeutics Inc (PRTO) Shares

The big news today is that Proteon Therapeutics Inc (NASDAQ:PRTO) has received Breakthrough Designation from the FDA for Vonapanitase, an investigational drug that may prolong the patency and reduce the failure of hemodialysis vascular access in patients with CKD.

In reaction, Proteon shares jumped nearly 25% to $1.70, as of this writing.

CEO Timothy Noyes commented, “We believe the decision by the FDA to grant vonapanitase a Breakthrough Therapy designation speaks to the clinical importance of fistula survival and use for hemodialysis to patients with chronic kidney disease. Our productive ongoing dialogue with the FDA has helped to create a clear path forward for vonapanitase, and we look forward to continuing to work closely with the FDA to expedite our development efforts for this important program.”

Maxim analyst Jason McCarthy also commented, “Breakthrough designation does represent elements of validation. PATENCY-2 is now more than halfway enrolled. This combined with data from PATENCY-1 suggests regulators see value and recognize the medical need. It also suggests to us that regulators are comfortable with the amended protocol for the PATENCY-2 trial which should increase the probability of success.”

McCarthy rates PRTO shares a Buy, with a price target of $6.00, which implies an upside of 362% from current levels. On the other hand, Oppenheimer’s Jay Olson reiterates a Hold rating on the stock, without listing a price target.
