SHANGHAI,Nov. 17,2020 -- Kangpu Biopharmaceuticals,a clinical-stage company based in Shanghai,China,announced that,after consulting with the U.S. Food and Drug Administration (FDA),the Company has initiated a Phase Ib/IIa clinical study of KPG-818 in patients with Systemic Lupus Erythematosus (SLE).

The Phase Ib/IIa multicenter,randomized,double-blind,placebo-controlled clinical study will evaluate the safety and tolerability,pharmacokinetics and preliminary efficacy of KPG-818 in patients with mild to moderate SLE.

About Systemic Lupus Erythematosus (SLE)

Systemic Lupus Erythematosus (SLE) is a complex,heterogeneous,inflammatory,chronic auto-immune disease in which the body's immune system attacks its own tissues,leading to widespread damage in various organs,including the kidneys,lungs,heart,brain,skin,joints,and blood vessels. As reported by Frost & Sullivan,there were approximately 7.7 million SLE patients in 2019 worldwide. In over 60 years,only one new treatment (Benlysta) has been approved for SLE by the FDA. With limited clinical treatment options available and no cure for the disease,effective management of SLE remains a huge challenge.

About KPG-818

KPG-818 is a novel generation of small molecule modulators of the CRBN E3 ubiquitin ligase complex CRL4-CRBN and potently induces the ubiquitination and degradation of Aiolos (IKZF3) and Ikaros (IKZF1),two members of the Ikaros family of zinc-finger transcription factors critical in B-cell development. In preclinical studies,KPG-818 demonstrated outstanding in vitro anti-inflammatory properties and broad spectrum of anti-proliferative activities as well as remarkable in vivo efficacy in animal models of multiple blood cancers. In the Phase I single ascending dose (SAD) clinical study recently completed in the U.S.,KPG-818 was well tolerated at all tested dose levels (2-30 mg) and demonstrated a favorable pharmacokinetic profile. KPG-818 is currently being developed in a Phase I study for the treatment of patients with hematological malignancies in the United States (NCT04283097 at www.clinicaltrials.gov). In addition,KPG-818 has recently been approved by the FDA for a Phase IIa clinical trial in patients with COVID-19 infection in the U.S.
