About this study

Official title: A Single Center, Non-randomized, Open-label Phase I Study to Investigate the Pharmacokinetics and Safety of SIM0417/Ritonavir After Single Dose Administration in Healthy Elderly Subjects

This is a non-randomized, open-label, single-dose, Phase I clinical study and plans to enroll 12-20 healthy elderly subjects aged 65 and above, including 3-6 subjects aged 75 and above, both men and women.

Read the detailed description

Each subject will receive SIM0417 combined with ritonavir administration. SIM0417 is single-dose administration, and ritonavir is administered 12 hours before SIM0417 administration (-12hours), at the time of SIM0417 administration (0hour) and 12hours (12hours), SIM0417 is administered under fasting condition, ritonavir is administered under fasting condition either after meal.

The dose of SIM0417 is 750 mg, and the dose of ritonavir is 100 mg.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SIM0417/Ritonavir in people with Elder, run by Jiangsu Simcere Pharmaceutical Co., Ltd. at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 24 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Juan Wu (18920299268, wujuan3@simcere.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cmax (time frame: Up to 72 hours from SIM0417 administration). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05826249.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Apr 2023; AzTrials last refreshed its copy on 8 Nov 2026.
