| SHANGHAI, Aug. 18, 2022 /PRNewswire/ -- GenFleet Therapeutics, a clinical-stage biotechnology company focusing on cutting-edge therapies in oncology and immunology, announced US Food and Drug Administration (FDA) has approved the clinical trial application for GFH312 in a randomized, double-blinded, placebo-controlled phase II monotherapy study. The trial will be conducted in patients with peripheral artery disease and with intermittent claudication at 15 research centers, including University of Colorado Anschutz Medical Campus. GenFleet completed the phase I study of GFH312 in Australia with data to be published in relevant international medical conference later this year. According to research, there are estimated over 200 million people worldwide living with peripheral artery disease (PAD) with prevalence ranging as high as 20% in populations aged 70 years or over. Most patients are either asymptomatic or have intermittent claudication (IC), but all with an increased risk for myocardial infarction, stroke and vascular-related mortality. There is a significant unmet medical need for PAD, given that currently no anti-inflammatory treatments have been approved globally. RIPK1 exhibits dual immunomodulatory effects and is a key regulator of multiple immune pathways. Many scientific publications have indicated that RIPK1-mediated inflammatory response plays a crucial part in the occurrence and development of PAD with IC. Preclinical data demonstrated GFH312 is able to inhibit RIPK1 kinase activity in human cells, down-regulate RIPK1 phosphorylation in animal models and curb the inflammatory response of animals’ nervous system. “The data from completed phase I trial in Australia demonstrated excellent safety profile and desirable PK & PD properties of GFH312. GFH312 is GenFleet’s first Phase 2-ready product in non-oncology indications. We wish to further confirm the safety and therapeutic effectiveness of GFH312 in the trial.” said Dr. Yu Wang, Chief Medical Officer of GenFleet Therapeutics. “GenFleet has launched a series of initiatives in global clinical development and strategic partnership this year. GFH312 is GenFleet’s first program entering into clinical trial in Australia, and now we are thrilled to see this program moving into phase II study in the US. This is a significant milestone for the company’s multi-regional clinical development. To date, no RIPK1 inhibitor has been approved for therapeutic use and we look forward to bringing more innovative therapies to benefit patients worldwide.” said Dr. Jiong Lan, Co-founder and Chief Executive Officer of GenFleet Therapeutics. The primary objective of this study is to evaluate the effect of GFH312 on symptomatic functional capacity among PAD patients with IC after 12 weeks of treatment. The study will also assess the safety, tolerability and pharmacokinetics of GFH312 and explore the beneficial impact of GFH312 on the quality of PAD patients’ life. Moreover, GenFleet is planning to start a double-blinded, randomized, placebo-controlled phase I study in China to support further phase II study in China for other potential indications.

Epidemiology, diagnosis and classification of peripheral artery disease (PAD), Nova Science Pub Inc, 2016 About peripheral arterial disease and intermittent claudication Peripheral arterial disease (PAD) is a chronic disease in which plaque builds up in the arteries and leads to stenosis or even complete occlusion. Narrowed vessels would reduce blood flow to the arms or legs and cause intermittent claudication and other cardiovascular symptoms. According to research, PAD affects almost 27 million people in US and Europe; in China, PAD prevalence amounts to 6% among people above 35 years old and PAD-affected population is calculated to exceed 40 million. At present, antiplatelet drugs, vasodilators, or drugs for prevention and treatment of venous thrombosis and systemic circulation embolism are commonly prescribed to relieve PAD symptoms. As a common symptom in vascular and neurological diseases, intermittent claudication (IC) is mainly caused by local ischemia and induces microvascular obstruction, leg weakness and intermittent walking difficulty. The symptoms can be alleviated in varying degrees and durations after stopping lower limb movement. About RIPK1 and GFH312 As a subtype of receptor interacting protein kinase family, RIPK1 is a central regulator of multiple immune signaling pathways. Widely expressed in human cells, the serine/threonine kinase of RIPK1 is most abundant in fat, endothelial and perivascular cell clusters and also discovered in immune cell clusters (dendritic cells, macrophages and T cells). Small-molecule RIPK1 inhibitors are expected to show efficacy for treating autoinflammatory and autoimmune diseases (including psoriasis, rheumatoid arthritis, ulcerative colitis, etc.). In vitro experiments demonstrate that GFH312 blocks the process of TNF-α-induced necroptosis. It’s observed in a variety of animal models that GFH312 can reduce inflammation and resist necroptosis; besides, low dosage of GFH312 can decrease the death risk caused by acute systemic inflammation and significantly improve the action capability of experimental animals. The phase I clinical trial data confirm the safety and tolerance of GFH312.
