NKTR Investor Alert: Nektar Therapeutics Securities Fraud Lawsuit - Investors With Losses May Seek to Lead the Class Action After Allegedly Inflating Trial Integrity Claims: Levi & Korsinsky
NEW YORK, April 27, 2026 (GLOBE NEWSWIRE) -- Levi & Korsinsky, LLP reminds purchasers of Nektar Therapeutics (NASDAQ: NKTR) securities of a pending securities class action.
THE CASE: A class action seeks to recover damages for investors who purchased NKTR securities between February 26, 2025 and December 15, 2025.

From a closing price of $53.30 on December 15, 2025, Nektar shares declined to $49.16 following the December 16 corrective disclosure, a loss of $4.14 per share representing a 7.77% single-day decline. The last day to move for lead plaintiff is May 5, 2026.
The December 16 Pre-Market Disclosure
Before the market opened on December 16, 2025, Nektar issued a press release revealing that the Phase 2b REZOLVE-AA trial had narrowly missed its primary endpoint of statistical significance. The lawsuit maintains that the market had priced NKTR shares based on repeated assurances that enrollment followed strict protocol standards and that the Company possessed the expertise to conduct rigorous clinical development. When the corrective disclosure removed these assumptions, the market repriced NKTR shares downward to reflect the newly revealed risk that four ineligible patients had compromised trial integrity.
Alleged Investor Damages and Loss Causation
The securities action contends that every share purchased during the Class Period carried artificial inflation attributable to concealed enrollment protocol failures:
How the Market Repriced NKTR Shares
As pleaded in the complaint, BTIG's report stated that the muted stock reaction despite the high-dose REZPEG meeting its optimistic scenario was "explained solely by" the four eligibility violations. Piper Sandler confirmed Nektar was "currently trading down given n=4 patients had major study eligibility violations." These analyst assessments support the claim that the $4.14 per-share decline was directly caused by the removal of artificial inflation, not by general market conditions or unrelated factors.

"When companies fail to disclose material information, shareholders may suffer significant losses. Here, the complaint charges that investors paid inflated prices for NKTR shares throughout a period when protocol violations in the Company's lead clinical trial were allegedly concealed." -- Joseph E.
