Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
* A subject will be eligible for inclusion in this study only if all of the following criteria are met:

1. Voluntarily signed written informed consent;
2. Ability to comprehend the purpose of the study; ability to co-operate with the investigator and comply with all study requirements;
3. Adult females aged between 18 and 55 years (inclusive);
4. Body weight between 50 and 100 kg (inclusive) and body mass index (BMI) within 18~32 kg/m2 (inclusive).

* Vital signs (measured after resting for 5 minutes seated position) within normal range, or outside the normal range and not considered clinically significant by the Investigator;
* Standard 12-lead ECG parameters (recorded after resting for 5 minutes in supine position) in the following ranges; QTc (Fridericia algorithm recommended) =470 ms, and normal ECG tracing, or abnormal ECG tracing not considered clinically relevant by the Investigator;
* Laboratory parameters demonstrating no clinically significant abnormalities, as determined by the Investigator. A total bilirubin outside the normal range may be acceptable if total bilirubin does not exceed 1.5 × ULN conjugated bilirubin (with the exception of a participant with documented Gilbert syndrome).
6. Self-report regular menstrual cycle (21-35 days), and planned to avoid menstruation from the first administration until 7 days after the last administration;

13. Subjects in a intercourse relationship must agree to use highly effective methods of contraception (as specified in Section 4.6.3) from informed consent obtained until 3 months after the last administration, and pregnancy test results must be negative at screening.

8. History of clinically severe relevant cardiovascular, hepatic, renal, pulmonary, gastrointestinal, endocrine, or neurological diseases that, in the investigator's opinion, may interfere with the aim of the study or affect the subject's safety;
9. Uncontrolled or acute illness that may complicate the study evaluation in the investigator's opinion;
10. History of hysterectomy;
11. Pelvic surgery within 90 days prior to screening;
12. Cervical cryotherapy or cervical laser treatment within 90 days prior to screening;
13. Intrauterine device insertion or removal within 90 days prior to screening;
14. Any antibiotic or antifungal therapy (intravaginal or systemic) within 30 days prior to screening;
15. Immunosuppressive therapy within 60 days prior to screening;
16. Ascertained or presumptive hypersensitivity (including allergies) to any ingredient of the investigational medicinal product (IMP); history of other significant anaphylaxis to drugs or allergic reactions in general;
17. Pregnant or lactating women, or women within 60 days of the last pregnancy;
18. Subjects who consume or are unable to abstain from products containing caffeine/xanthine within 24 hours before a visit or admission;
19. History of drug or alcohol abuse within 1year prior to screening, or a positive result of drug abuse or alcohol breath test at screening or check-in;
20. Previously dosed with an investigational drug within 3 months prior to Day 1 or still participating in another trial at the time of screening;
21. Any vaccination from the 28 days prior to administration of the first dose until 28 days after the last dose;
22. Those considered by the investigator as inappropriate to participate in the study.
