Endurance RP Limited is pleased to announce the successful completion of prespecified data analysis from the United States study mandated patient reported outcome for PE. The PRO, the PE Bothersome Evaluation Questionnaire was developed as the key final step for assessment of efficacy ahead of the Phase III randomised clinical trial already planned for the US.
Mandated patient reported outcome ("PRO") for PE
Prespecified data analysis from the 16 centre United States (the "US") study undertaken to validate the US Food and Drug Administration (the "FDA") mandated patient reported outcome ("PRO") for PE has been successfully completed. The PRO, the PEBEQ™ was developed compliant to FDA guidelines as the key final step for assessment of efficacy ahead of the Phase III randomised clinical trial ("RCT"), which is already planned for the US.
In this study, PSD502, marketed as Fortacin™ in the European Union and the United Kingdom, produced substantial changes in intravaginal latency time ("IELT") and reduced the level of distress experienced by patients, as reflected in the PEBEQ™.
These results are entirely consistent with the previous extensive Phase III RCTs that were successfully completed prior to approval by the European Medicines Agency. The changes were clinically and statistically significant both from baseline and from placebo, resulting in an eight-to-nine-fold increase from pre-treatment IELT values. Also consistent with previous RCTs, compliance with therapy and with study requirements was high (over 92% completed in this study), and side effects were minimal.
The PRO, the PE Bothersome Evaluation Questionnaire ("PEBEQ™")
The PRO, the PE Bothersome Evaluation Questionnaire ("PEBEQ™") was developed compliant to FDA guidelines. Clinically and statistically significant differences between Fortacin™ and placebo were observed in the FDA-favoured domain ("Item 3") of the PEBEQ™ (p< 0.0008). At the request of the FDA, Item 3 was designed to determine the degree of "bother" that the patients were experiencing due to the condition. For PRO validation, excellent correlations were also observed between changes in Item 3 of the PEBEQ™ and the domains of sexual satisfaction, control and distress captured using the Index of PE ("IPE"), one of two PROs used in previous studies. The terms such as "bother" are important because they are used in the final approved prescribing information ("PI").
Jamie Gibson, Chief Executive Officer of the Company, said, "The study confirms the safety and efficacy of Fortacin™. The new data will be used to refine the final Phase III RCT protocol, which is already prepared, and suitable clinical sites screen for expedient and good clinical practice enrolment. The formal registration of the Phase II validation study of Fortacin™ is a critical and positive step towards making the new drug application ("NDA") submission and ultimately achieving all necessary FDA and other US regulatory approvals needed to commercialise of Fortacin™ in the US, its most significant potential market."
The Group anticipates that the results of the study will be submitted to the FDA by mid-August 2021. On the likely assumption that the study is sufficient to convince the FDA that the PEBEQ™ serves as an appropriate measure for support of a label or PI claim, the pivotal Phase III RCT study could commence in the latter half of 2021, with NDA submission possible in late 2022, giving a Prescription Drug User Fee Act date at the end of 2023.
