RiboX Therapeutics Advances Circular RNA Therapy for Xerostomia
RiboX Therapeutics Begins First Patient Dosing in Clinical Trial
RiboX Therapeutics Ltd., a trailblazing biopharmaceutical company dedicated to developing advanced circular RNA therapies, has made a significant announcement regarding its pioneering clinical trial. The company has initiated the dosing of the first patient in its Phase I/IIa clinical trial, named SPRINX-1, aimed at assessing the safety and effectiveness of RXRG001. RXRG001 represents a breakthrough in treatment options for individuals suffering from radiation-induced xerostomia (RIX) and hyposalivation, common side effects for patients undergoing radiation therapy for head and neck cancer.
Xerostomia, often referred to as dry mouth, can severely impact a patient's quality of life. This condition emerges when radiation therapy damages salivary glands, leading to reduced saliva production. The repercussions can include difficulties in eating and speaking, impaired oral health, and an overall decline in well-being. Thus, the development of new treatment options like RXRG001 addresses a crucial unmet medical need within this patient population.
Principal Investigator Dr. Henry T. Hoffman, a respected professor in Otolaryngology, expressed optimism about the clinical trial, highlighting the need for effective therapies in this area. He stated, “Patients suffering from radiation-induced xerostomia are in dire need of new therapeutic options. RXRG001 introduces an innovative approach offering hope for my patients.” His enthusiasm is shared by the team at RiboX, reinforcing their commitment to the cause.
Haifa Tyler, Head of Clinical Operations at RiboX, echoed this sentiment, noting their privileged collaboration with esteemed Principal Investigators. This collaborative effort underscores their commitment to advancing the clinical trial and finding solutions that significantly enhance patients' lives affected by the aftermath of cancer treatment.
Significance of RXRG001 in Clinical Research
The progress of RXRG001 marks a pivotal moment not only for RiboX but also for individuals battling xerostomia. Dr. Yizhen Xu, Chief Medical Officer of RiboX, hailed this development as an important milestone in the journey of introducing novel treatments to affected patients around the globe. RXRG001, built on innovative circular RNA technology, is set to revolutionize the therapeutic landscape.
RXRG001 utilizes circular RNA, a next-generation therapy that promises high levels of protein expression while demonstrating low immunogenicity and stability in manufacturing. The formulation contains circular RNA coding for human aquaporin 1 (hAQP1), a vital water channel protein in cell membranes, encapsulated in lipid nanoparticles (LNPs). The therapeutic effect is aimed at enhancing saliva production by restoring water permeability through hAQP1 overexpression, effectively alleviating symptoms of dry mouth that many patients experience.
Before reaching this clinical trial stage, RXRG001 underwent rigorous non-clinical studies that confirmed its favorable risk and benefit profile. Notably, animal model trials showed that a single administration of RXRG001 could sustain increased salivary flow for up to four weeks.
The Journey Ahead for RiboX
As the first-ever circular RNA therapy to receive FDA IND clearance, RXRG001 marks a significant advancement in the field. Founded in 2021, RiboX Therapeutics has rapidly evolved as a leading entity in circular RNA therapeutics, co-founded by experts including Drs. Ling-Ling Chen, Dan Peer, and Weiyi Zhang. The company's robust pipeline includes diverse therapeutic areas, such as radiation-induced xerostomia, monogenic diseases, autoimmune disorders, and metabolic diseases.
The company's operational footprint spans across several countries, demonstrating its global commitment to pioneering research in next-generation RNA therapies. RiboX aims to overcome current limitations associated with traditional mRNA therapeutics while unleashing the vast potential of RNA medicines.
RiboX’s ongoing dedication to innovation in research is driven by the goal of improving patient lives worldwide through effective, cutting-edge treatments. The clinical trials are expected to gather significant insights that could lead to transformative therapies for patients in dire need.
