Insights
This Phase 2 trial announcement represents a strategic advancement in Nektar's development of rezpegaldesleukin for type 1 diabetes treatment. The collaboration with TrialNet, a leading international diabetes research network, significantly enhances the trial's credibility and execution potential. The study's design is particularly robust, incorporating both mixed meal tolerance testing and C-peptide preservation measurements - important markers that directly correlate with beta cell function and disease progression.
The trial's focus on new onset stage 3 T1D is strategically important, as early intervention in the disease process offers the highest potential for preserving pancreatic function. The dual mechanism of rezpegaldesleukin - dampening inflammation while restoring immune balance through Treg cell expansion - addresses multiple pathogenic pathways in T1D, potentially offering superior efficacy compared to single-mechanism approaches.
From a commercial perspective, Nektar's retention of all rights to rezpegaldesleukin is particularly valuable, as the global type 1 diabetes therapeutics market represents a substantial opportunity, with current treatments primarily focused on insulin replacement rather than disease modification. Success in this trial could position Nektar as a pioneer in disease-modifying T1D therapeutics, addressing an unmet need in a market projected to grow significantly due to increasing disease prevalence and diagnosis rates in younger populations.
The 12-month study duration, with equal treatment and follow-up periods, will provide important data on both immediate efficacy and durability of response - key factors for regulatory approval and commercial success in autoimmune disease treatments. The inclusion of multiple secondary endpoints, including HbA1c levels and insulin requirements, will offer comprehensive insights into the drug's clinical utility and potential market positioning.
-- TrialNet to conduct the Phase 2 randomized, placebo-controlled clinical study --
Rezpegaldesleukin is a novel agonistic T regulatory (Treg) cell biologic that is designed to both dampen the inflammatory response and simultaneously restore immune balance by directly expanding functional Treg cells and engaging multiple immunoregulatory pathways. Tregs are known to play a key role in the pathogenesis of T1D.1
Under the agreement, TrialNet will conduct the Phase 2 randomized, double-blind, placebo-controlled, clinical trial to investigate the safety and potential efficacy of rezpegaldesleukin in approximately 70 adults and children with new onset stage 3 T1D. Nektar will supply rezpegaldesleukin for the trial and will provide support for the study, including pharmacokinetic and other analyses. Nektar will retain all rights to the rezpegaldesleukin program under the collaboration.
"We are looking forward to collaborating with the exceptional team at TrialNet to advance rezpegaldesleukin in an important clinical study to evaluate its potential in patients with newly-diagnosed type 1 diabetes," said Jonathan Zalevsky, PhD, Senior Vice President and Chief Research & Development Officer of Nektar. "Our goal is to initiate this study in 2025. We are proud to support TrialNet's mission of advancing innovative mechanisms aimed at slowing or stopping the progression of type 1 diabetes."
The new study will use a mixed meal tolerance test (MMTT) to measure the efficacy of rezpegaldesleukin or placebo for preserving C-peptide area under the curve over a 12-month duration comprised of a 6-month treatment period and a 6-month follow-up. Secondary objectives include pharmacokinetics, pharmacodynamics, and additional disease assessments including HbA1c levels and patient insulin requirements.
"We are excited to explore the potential of the Treg stimulator rezpegaldesleukin as a novel investigational candidate in people with type 1 diabetes," said Kevan C. Herold, MD, TrialNet Chair and C.N.H. Long Professor of Immunobiology and Medicine at Yale University. "Rezpegaldesleukin provides an important opportunity to evaluate the therapeutic potential of using Tregs to directly target T-cell and cytokine-mediated destruction of beta-cells in the pancreas."
About Rezpegaldesleukin
Autoimmune and inflammatory diseases cause the immune system to mistakenly attack and damage healthy cells in a person's body. A failure of the body's self-tolerance mechanisms enables the formation of the pathogenic T lymphocytes that conduct this attack. Rezpegaldesleukin is a potential first-in-class resolution therapeutic that may address this underlying immune system imbalance in people with many autoimmune and inflammatory conditions. It targets the interleukin-2 receptor complex in the body in order to stimulate proliferation of powerful inhibitory immune cells known as regulatory T cells. By activating these cells, rezpegaldesleukin may act to bring the immune system back into balance.
Rezpegaldesleukin is wholly-owned by Nektar Therapeutics. It is being developed as a self-administered injection for a number of autoimmune and inflammatory diseases. It is currently being evaluated in the REZOLVE-AD study, a randomized, double blind, placebo-controlled Phase 2b clinical trial for treatment of patients with moderate-to-severe atopic dermatitis (NCT06136741). In addition to the REZOLVE-AD study, it is also being evaluated in the REZOLVE-AA study, a randomized, double blind, placebo-controlled Phase 2b clinical trial for treatment of patients with severe-to-very-severe alopecia areata (NCT06340360).

About Type 1 Diabetes (T1D)
T1D is an immune-mediated disease in which insulin-producing beta cells are completely, or almost completely, destroyed, resulting in life-long dependence on exogenous insulin.2 It is a chronic and potentially disabling disease that represents a major public health and clinical concern. Most individuals with newly diagnosed T1D have
