Executive Accountability: Jonathan Zalevsky Named in Securities Action
NEW YORK, April 29, 2026 /PRNewswire/ -- Levi & Korsinsky, LLP notifies investors that Jonathan Zalevsky, Chief Research and Development Officer of Nektar Therapeutics (NASDAQ: NKTR), is named as an individual defendant in a securities class action filed on behalf of shareholders who purchased securities between February 26, 2025 and December 15, 2025.

Nektar shares fell $4.14 per share, or 7.77%, after the Company disclosed that four ineligible patients were included in the Phase 2b REZOLVE-AA trial, causing the primary endpoint to miss statistical significance.
Zalevsky's Role During the Class Period
As Nektar's Chief Research and Development Officer, Zalevsky bore direct responsibility for the scientific and operational conduct of the Company's clinical programs. The complaint identifies Zalevsky as the executive who repeatedly made specific public representations about the REZOLVE-AA trial's enrollment criteria and patient eligibility screening across multiple quarterly earnings calls.
What Zalevsky Allegedly Oversaw
The action contends that Zalevsky personally assured investors on at least three separate occasions that patients enrolled in the REZOLVE-AA trial met strict eligibility standards:
- On March 12, 2025, Zalevsky stated patients "had to present with severe-to-very-severe disease" at SALT 50 to SALT 100 "for at least six months" to be eligible
- On May 8, 2025, Zalevsky reiterated the identical eligibility criteria during the Q1 2025 earnings call
- On November 6, 2025, Zalevsky again confirmed that patients with unstable alopecia areata or diffuse alopecia "were excluded from the study"
- Despite these assurances, four patients with major eligibility violations were randomized into the trial, including patients diagnosed less than six months prior and patients who had not completed the required 8-week washout period
Zalevsky's Certifications and Liability
As alleged in the complaint, Zalevsky's 2024 annual bonus of $431,885 was awarded based in part on "maintaining on-track enrollment" of the REZOLVE-AA clinical trial. The lawsuit asserts this created a direct financial incentive tied to enrollment completion, raising questions about whether protocol adherence was compromised to meet timeline targets.
"Individual officers who sign SEC certifications bear personal responsibility for the accuracy of corporate disclosures. When an executive makes repeated, specific assurances about clinical trial integrity, investors are entitled to rely on those statements." -- Joseph E. Levi, Esq.
Section 20(a) Context for Zalevsky
The complaint names Zalevsky as a controlling person under Section 20(a) of the Securities Exchange Act of 1934, alleging he possessed the power and authority to control the contents of Nektar's press releases and public communications regarding the REZOLVE-AA trial. As the executive who designed and oversaw the clinical development program, the action claims Zalevsky had access to material information about enrollment compliance that was not disclosed to the investing public.
