What are Wall Street analysts saying about TESARO stock?

Here are some recent quotes from research analysts about TESARO stock:
  • 1. Cantor Fitzgerald analysts commented, ": 12-month PT of $68 on shares of TSRO. Bloomberg reported last week that Tesaro was exploring a sale. We think that the company remains undervalued based on 1) PARP inhibitor potential in first-line ovarian cancer and 2) potential with its immuno-oncology platform (licensed from AnaptysBio, ANAB, OW, covered by Eliana Merle) that is beginning to shape up with data readouts. We also believe that it can take time for deals to emerge, so we think that this press article could be a way of garnering interest for the company beyond potentially initial interest. In the past, we think that this company had been a potential takeout interest from biopharmaceutical companies." (11/19/2018)
  • 2. According to Zacks Investment Research, "TESARO's drug, Zejula has performed well since its approval in early 2017, gaining lead in U.S. ovarian cancer market share in the PARP inhibitor segment. The drug also has bright prospects, given the tremendous demand for PARP inhibitors. Moreover, collaborations with several large pharma companies for the development of Zejula generates a cash flow stream for TESARO and enables sharing of R&D costs. TESARO’s efforts for label expansion of Zejula are also encouraging. However, TESARO is heavily dependent on Zejula for growth, which concerns us. Meanwhile, competition in the PARP inhibitor segment is rising with two other approved drugs and several companies developing their candidates. TESARO’s shares have underperformed the industry so far this year. Loss estimates have widened ahead of the company’s Q3 earnings release. The company has a mixed record of earnings surprises in recent quarters." (10/23/2018)
  • 3. HC Wainwright analysts commented, "Updates to Varubi’s Label; Reiterate Buy and $158 Price Target Prescribing information update, no products being recalled. After the close on January 12, TESARO announced that it has updated the Varubi injectable emulsion package insert in collaboration with the FDA. The changes to the label include modifications to the Contradictions, Warnings and Precuations, and Adverse Reactions section to inclde anaphylaxis, anaphylactic shock and other serious hypersensitivity reactions associated with the use of Varubi injectable emulsion. The company indicated that anaphylaxis, anaphylactic shock and other hypersensitivity reactions have been reported in the postmarketing setting, with some cases requiring hospitalization. These side effects were noted during or soon after the infusion of Varubi, with most reactions observed during the first few minutes of administration." (1/12/2018)
