RADNOR, Pa., Dec. 17, 2018 (GLOBE NEWSWIRE) -- The law firm of Kessler Topaz Meltzer & Check, LLP reminds Nektar Therapeutics (Nasdaq: NKTR) (“Nektar”) investors that a securities fraud class action lawsuit has been filed in the United States District Court for the Northern District of California against Nektar on behalf of purchasers of Nektar securities between November 11, 2017 through October 2, 2018, inclusive (the “Class Period”).
Important Deadline Reminder: Investors who purchased Nektar securities during the Class Period may, no later than December 31, 2018, seek to be appointed as a lead plaintiff representative of the class.

According to the complaint, Nektar is a research-based biopharmaceutical company that discovers and develops innovative medicines in areas of high unmet medical need. Nektar’s research and development pipeline of new investigational drugs includes treatments for cancer, autoimmune disease and chronic pain. NKTR-214, Nektar’s lead immune-oncology candidate, is a biologic with biased signaling through one of the IL-2 receptor subunits (CD 122) that can stimulate proliferation and growth of tumor-killing immune cells in the tumor micro-environment and increase expression of PD-1 on these immune cells.
The Class Period commences on November 11, 2017, when Nektar issued a press release announcing “First Data for NKTR-214 in Combination with OPDIVO® (nivolumab) for Patients with Stage IV Melanoma, Renal Cell Carcinoma and Non-Small Cell Lung Cancers, Including Patients with PD-L1 Negative Status, Revealed at SITC 2017”.
According to the complaint, on October 1, 2018, Plainview LLC (“Plainview”) published a report entitled “NKTR-214: Pegging the Value at Zero”. The report addressed the efficacy of Nektar’s lead clinical-stage drug NKTR-214, which Nektar touted as “a promising treatment for cancer, particularly in combination with checkpoint inhibitors.” The Plainview report stated that “Nektar hypothesized that IL-2 [a naturally occurring cytokine] could be improved by adding polyethylene glycol molecules to it (pegylating it) to extend the half-life and block interaction with” a specific receptor, but that “[u]nfortunately, the anticipated benefits did not materialize and pegylation has proved to be a drag on efficacy.” The Plainview report asserted that the core concept of Nektar’s plan to develop NKTR-214 into “a new universal cancer treatment” “has never worked in practice”, and further asserted that Nektar’s decision to only disclose certain trial results represented “an unprecedented level of data opacity.”
Following this report, Nektar’s stock price fell $5.63 per share, or 9.24%, over the following two trading sessions, closing at $55.33 per share on October 2, 2018.
The complaint alleges that throughout the Class Period, the defendants made false and/or misleading statements and/or failed to disclose that: (i) prior studies which attempted to pegylate IL-2 failed; (ii) NKTR-214’s extended half-life was unlikely to result in efficacy and created additional high-dosing safety concerns; (iii) NKTR-214 was less effective than IL-2 alone; (iv) the combination of NKTR-214 with nivolumab has not yet demonstrated significant positive results; and (v) as a result, Nektar’s public statements as set forth above were materially false and misleading at all relevant times.
