Endurance RP: Excellent Positive Results from Phase 3 Randomised Clinical Trial of Fortacin(TM)/Senstend(TM) in China
HONG KONG, Apr 17, 2023 – (ACN Newswire via SEAPRWire.com) – Endurance RP Limited (“Endurance” or the “Company” and collectively with its subsidiaries, the “Group”; stock code: 0575.HK) is pleased to announce its commercial strategic partner Wanbang Biopharmaceutical Co., Ltd. (“Wanbang Biopharmaceutical”) has successfully completed the Phase 3 double-blind placebo-controlled study of Senstend(TM) in China for the treatment of premature ejaculation (“PE”).
The study recorded excellent positive results which met all four co-primary endpoints of Intra-vaginal Ejaculation Latency Time (“IELT”), Index of Premature Ejaculation (“IPE”) Ejaculatory Control and IPE Sexual Satisfaction domains and IPE Distress. Compared to both baseline and placebo, Senstend(TM) produced clinically and statistically significant increases in IELT, ejaculatory control and satisfaction and reduction in distress. Consistent with our previous studies undertaken in Europe and the United States (“US”), Senstend(TM) was well-tolerated by both Chinese patients and partners and no new side effects were reported.
In this study, there was a study population of 295 male patients aged 20 years or above who were diagnosed with PE, with 197 patients in the Senstend(TM) group and 98 in the placebo group. Patients were treated for three months at multiple sites in China.
Jamie Gibson, CEO of the Group, said, “We are delighted with the highly significant and positive results from the Phase 3 clinical study in China, which reinforces the results from the European and US Phase 3 clinical studies. This represents an important milestone in the regulatory submission process in China. We now look forward to our commercial partner in China submitting the New Drug Application (“NDA”) to National Medical Products Administration (“NMPA”) by the end of Q3 2023 with approval expected 12 months later.”
Jamie Gibson further added, “Senstend(TM) has the potential to help about 9 million patients in China during its first year of launch, growing to over 170 million by the tenth year. Our strong partner Wanbang Biopharmaceutical, who benefits from being part of the Fosun network. This company has the marketing expertise established e-commerce platforms and an unrivalled nationwide logic and distribution through Sinopharm, China’s number one pharmaceutical and healthcare distributor, through its network of hospitals, clinics and pharmacies to ensure the commercial success of Senstend(TM) in China.”
Commercial Milestone Payments from Wanbang Biopharmaceutical
All costs of the clinical trials, including any other associated regulatory and submission costs for Senstend(TM) are covered by Wanbang Biopharmaceutical. The group will receive US$5 million (or approximately HK$39 million) (before deduction of PRC withholding tax) assuming NMPA approval for importing Senstend(TM) is granted and US$2 million (or approximately HK$15.60 million) (before deduction of PRC withholding tax) upon first commercial sale of Senstend(TM) in China, from Wanbang Biopharmaceutical.
Additionally, as disclosed on 3 December 2018, there are other significant payments payable to the Group from Wanbang Biopharmaceutical.

Patients have responded positively, with the first batch of units in Germany experiencing strong demand.
