What are analysts saying about Prothena Corporation PLC stock?

Here are some recent quotes from research analysts about Prothena Corporation PLC stock:

  • 1. Cantor Fitzgerald analysts commented, "Gotta be in it to win it. The logic behind impeding cell trafficking as a means treating T cell-mediated autoimmune disorders has been established with Tysabri in relapsing forms of MS, so the merits of pursuing non-CNS indications makes abundant sense to us." (9/28/2017)
  • 2. According to Zacks Investment Research, "The narrower-than-expected loss in the second quarter was encouraging. Prothena’s efforts on developing its pipeline are encouraging. The company's license agreement with Roche for the development and commercialization of selected antibodies targeting alpha-synuclein is a big positive. The collaboration not only boosts Prothena’s pipeline development but also provides it with funds in the form of research reimbursement and milestone payments. Prothena recently earned a $30 million of milestone payment from Roche. The company’s shares have outperformed the industry in the past one year. We expect investor focus to remain on further updates from its late-stage candidate, NEOD001. However, Prothena is highly dependent on its collaboration partners for the development of its candidates. The company itself does not have enough resources to independently conduct studies on its candidates." (8/11/2017)
  • 3. Instinet analysts commented, "We are initiating on Prothena Corporation (PRTA) with a Buy rating and an $87 target price. We recommend owning PRTA shares ahead of Phase 2b PRONTO trial readout expected in early 2018 for lead asset NEOD001 in AL amyloidosis (a >$1.5bn peak sales opportunity). We view the pullback from 2016 highs and recent lows as an opportunity to accumulate the shares ahead of PRONTO data. Positive results from PRONTO based on change in NT-proBNP, a biomarker that NEOD001 substantially moved, yielding 53% responder rate in an early Phase 1/2b, are likely to support a conditional approval in the EU by 2019. In addition, we expect biomarker data from the PRX003 Phase 1b study to define mechanistically the breadth opportunity for MCAM/Th17-cell targeting in autoimmune disease, a potential multibillion dollar opportunity that, in our view, will raise the floor on PRTA's valuation. PRX002 could become a strong driver of PRTA's valuation in out years; however, given few near-term catalysts, it is unlikely to be a driver for PRTA shares in the next 12 months." (3/1/2017)
