SAN FRANCISCO, CA, USA I June 4, 2020 I Nektar Therapeutics (NASDAQ:NKTR) today announced the presentation of results from the Phase 1b study evaluating multiple ascending doses of NKTR-358, a first-in-class T regulatory cell stimulator, which is being developed as a potential therapeutic for a range of autoimmune disorders, including systemic lupus erythematosus (SLE).
The data, which were presented during the Annual European Congress of Rheumatology (EULAR 2020) in a virtual congress format, show that NKTR-358 was safe and well tolerated in patients with mild-to-moderate SLE and led to a marked and selective, dose-dependent expansion of regulatory T cells (Tregs) that was maintained over multiple administrations.
NKTR-358 is designed to correct an underlying immune system imbalance in patients with autoimmune conditions, which is associated with reduced numbers and impaired function of powerful inhibitory immune cells, known as T regulatory (Treg) cells. NKTR-358 works by targeting the interleukin-2 (IL-2) receptor complex in the body to stimulate proliferation of the body’s own Treg cells and increase their suppressive functional activity.
NKTR-358 was discovered by Nektar and is being co-developed in partnership with Eli Lilly and Company.
“The results in patients with lupus presented at this year’s EULAR Congress further support the potential of NKTR-358, through its stimulation of immune-inhibitory Treg cells, to restore normal self-tolerance mechanisms that are out of balance in patients with systemic lupus erythematosus,” said Brian Kotzin, Senior Vice President, Clinical Development and Head of Immunology at Nektar. “Based upon these data, Nektar and our partner Lilly are advancing NKTR-358 into a Phase 2 study in patients with moderate to severe SLE, which will be initiated this summer.”
The randomized, double-blind, multiple-ascending dose Phase 1b study being presented at 2020 EULAR evaluated safety, pharmacokinetics (PK) and pharmacodynamics (PD) in a total of 48 SLE patients across 4 separate ascending dose cohorts who received subcutaneous Q2W doses of NKTR-358 (n=9 per cohort) or placebo (n=3 per cohort). Subjects were treated for a total of six weeks.
Key highlights from today’s data presentation include:
- NKTR-358 was safe and well tolerated in patients with mild-to-moderate SLE
- Safety profile was similar between single and repeat administrations
- Data show dose-proportional pharmacokinetics and prolonged exposure, with a half-life of 10–13 days
- NKTR-358 elicited a marked and selective, dose-dependent expansion of CD25bright Tregs in patients with mild-to-moderate SLE, which was maintained through multiple administrations
- Similar extent and magnitude of induction as observed in the SAD study in healthy volunteers
Nektar will host a call tomorrow for analysts and investors to review the data presented at EULAR 2020. Details of the call are as follows:
Date and Time: Friday, June 5, 2020 at 11:00 a.m. Eastern Daylight Time
Dial- in: (877) 881-2183 (toll-free) or (970) 315-0453 (access code 1170058)
Investors and analysts can also view slides and listen to the live audio webcast of the presentation at https://edge.media-server.com/mmc/p/aaf3wx35. The event will also be available for replay for two weeks on the company’s website, www.nektar.com.
About NKTR-358 (LY3471851*)
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. NKTR-358 is a potential first-in-class resolution therapeutic that may address this underlying immune system imbalance in people with different 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, NKTR-358 may act to bring the immune system back into balance. Nektar entered into a strategic collaboration with Lilly in 2017 to develop and commercialize NKTR-358.
NKTR-358 is being developed as a self-administered injection for a number of autoimmune and inflammatory diseases. It is currently being evaluated in two separate Phase 1b studies in patients with atopic dermatitis (NCT04081350) and psoriasis (NCT04119557).
