The World’s First-in-Class <\/b>Intrauterine Drug-Eluting <\/b>System <\/b><\/p>\n

SHANGHAI<\/span><\/span>, Aug. 23, 2024<\/span><\/span> \/PRNewswire\/ — Corina Intrauterine Drug-Eluting <\/b>System<\/b> (“Corina”),<\/b> developed by Yipurun (Shanghai<\/span>) Biotechnology Co., Ltd. (“YPR”), has received approval in China<\/span> (G.X.Z.Z. 20243181461) for use in patients with moderate-to-severe intrauterine adhesions (IUA) who undergo transcervical resection of adhesions (TCRA). The approval for this indication is based on a randomized controlled clinical trial that demonstrated Corina’s superior efficacy compared to the standard-of-care. Corina is a first-in-class treatment focused on promoting female reproductive health through the prevention of intrauterine re-adhesion risk post TCRA, and the improvement of endometrial growth.<\/p>\n

Intrauterine adhesions (IUA) are the formation of scar tissues in the endometrial cavity as a result of damages to the endometrial basal layer of the uterus, which leads to the partial or complete occlusion of the cervical canal and uterine cavity. Clinically, IUA can cause a range of symptoms such as reduced menstrual flow, amenorrhea, infertility and recurrent miscarriage \u2013 thereby posing a serious threat to the reproductive health of women of childbearing age. Currently, the incidence rate of IUA in China<\/span> remains high, and continues to grow due to an increased number of intrauterine interventions. Research in this field show the incidence rate of IUA in China<\/span> to be as high as 25% in women who have had prior abortion or curettage procedures [1]<\/sup> \u2014 this has become a key driver of reduced menstrual flow and secondary infertility in women of childbearing age. As a standard surgical procedure to treat IUA, TCRA separates the adherent tissues and restores the anatomical shape of the uterine cavity. Surveys show 1.6 to 1.8 million patients in China<\/span> undergo TCRA every year, but the recurrence rate of IUA after surgery is still as high as 62.5% [2]<\/sup>; and the pregnancy success rate of patients after TCRA surgery is only 22.5%~33.3% [3-4]<\/sup>. Over the years, a variety of adjuvant therapies, such as uterine cavity isolation barriers and hormonal treatments, have emerged with limited efficacy.<\/p>\n

Corina is an innovative drug-device-combination therapy made from non-degradable, medical grade material, carrying the active ingredient estradiol. Designed to conform to the shape of the female uterus, Corina acts as a physical barrier upon insertion, and enables targeted delivery of estradiol to the endometrium. With YPR’s proprietary controlled-release technology, Corina can continuously release the active substance up to 60 days post procedure to promote endometrium growth.<\/p>\n

The registration study results of Corina have demonstrated statistically significant and clinically meaningful reduction in intrauterine adhesion at 60 days post procedure, compared to standard-of-care therapy. Corina has also shown meaningful improvement in endometrial thickness from baseline at 60 days post procedure, compared to standard-of-care therapy.<\/p>\n
