"Dysfunctions in Treg cell biology are implicated in the breakdown of immune self-tolerance, which is one of the underlying mechanisms involved in autoimmune and inflammatory diseases such as lupus, atopic dermatitis and psoriasis," said
Earlier this year, Nektar presented initial results of a first-in-human Phase 1a single-ascending dose study of NKTR-358 in healthy volunteers at the Annual
Atopic dermatitis (AD), also known as eczema, is a chronic, inflammatory skin disease which results in widespread rashes and patches of itchy skin, which can become thickened, cracked, raw or leak fluid when scratched. About 6.6 million adults report moderate-to-severe symptoms of AD1. AD is commonly associated with an individual or family history of asthma, hay fever, food allergy and/or other allergic diseases.
Psoriasis is an immune-mediated skin disease that causes raised, red, scaly patches to appear on the skin typically affecting the outsides of the elbows, knees or scalp. According to the World Psoriasis Day consortium, 125 million people worldwide—2 to 3 percent of the total population—have psoriasis2.
NKTR-358 is also being evaluated in a double-blind, randomized, placebo-controlled Phase 1b study in adults with systemic lupus erythematosus (SLE). The study will evaluate the safety, tolerability, pharmacokinetics and immunological effects of multiple ascending doses of NKTR-358 in approximately 50 adults with SLE. For more information, please visit clinicaltrials.gov and search NCT03556007.
About the Phase 1b Study in Psoriasis
The Phase 1b study is a double-blind, randomized, placebo-controlled multiple-dose study of NKTR-358 and will evaluate the safety, tolerability and pharmacokinetics of NKTR-358 in approximately 40 adults with plaque psoriasis. Exploratory objectives include assessment of disease activity and biomarkers.
About the Phase 1b Study in Atopic Dermatitis
The Phase 1b study is a double-blind, randomized, placebo-controlled multiple-dose study of NKTR-358 and will evaluate the safety, tolerability and pharmacokinetics of NKTR-358 in approximately 40 adults with atopic dermatitis. Exploratory objectives include assessment of disease activity and biomarkers. For additional information visit clinicaltrials.gov and search NCT04081350.
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 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, NKTR-358 may act to bring the immune system back into balance.
NKTR-358 is being developed as a self-administered injection for a number of autoimmune and inflammatory diseases.
Cautionary Note Regarding Forward-Looking Statements
This press release contains forward-looking statements which can be identified by words such as: "believe," "design," "could," "plan," "may," "will" and similar references to future periods. Examples of forward-looking statements include, among others, statements we make regarding the expected benefits of NKTR-358, the ability to obtain useful data from clinical studies of NKTR-358, and the future clinical development plans for NKTR-358. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Our actual results may differ materially from those indicated in the forward-looking statements. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause our actual results to differ materially from those indicated in the forward-looking statements include, among others: (i) NKTR-358 is in early-stage clinical development and there are substantial risks that can unexpectedly occur for numerous reasons including negative safety and efficacy findings in clinical studies notwithstanding positive findings in prior studies; (ii) clinical study outcomes of NKTR-358 remain very unpredictable and it is possible that a given clinical study could fail due to efficacy, safety or other important clinical findings, wherein any failure of a clinical trial for NKTR-358 in particular indication could prevent further development for all indications; (iii) the timing of the commencement or end of clinical trials and the availability of clinical data may be delayed or unsuccessful due to regulatory delays, slower than anticipated patient enrollment, manufacturing challenges, changing standards of care, evolving regulatory requirements, clinical trial design, clinical outcomes, and competitive factors; (iv) scientific discovery of new therapeutics is an inherently uncertain process and the future success of applying our technology platform to potential new drug candidates (such as NKTR-358) is therefore highly uncertain and unpredictable; (v) patents may not issue from our patent applications for NKTR-358, patents that have issued may not be enforceable, or additional intellectual property licenses from third parties may be required; and (vi) certain other important risks and uncertainties set forth in Nektar's Quarterly Report on Form 10-Q filed with the
