About this study

Official title: A Phase I, Randomized, Parallel-Controlled, Single and Multiple Ascending Dose Clinical Study to Evaluate the Safety, Tolerability, and Pharmacokinetic Profile of CX2101A Enteric-Coated Tablets in Healthy Chinese Adult Subjects

This study is divided into two parts, including Part I: a randomized, open-label, positive drug-controlled, single ascending dose (SAD) study, a food effect (FE) study, and Part II: a randomized, double-blind, placebo-controlled, multiple ascending dose (MAD) study.

Read the detailed description

Part I: Single Ascending Dose (SAD) and Food Effect (FE) Study Combined SAD and FE Study (N=42): The SAD portion is integrated with the FE study, comprising 5 dose groups: 20 mg, 80 mg, 160 mg, 300 mg, and 600 mg. The trial commences with the low-dose group and in a sequential manner. As subjects in a given dose group of CX2101A complete their safety assessments, the investigator evaluates whether the low-dose group has met the dose-escalation termination criteria. If not, the trial escalates to the next dose level.

SAD Study Enrollment: The SAD study aims to enrolls a total of 42 healthy subjects. The 20 mg dose group will enroll 4 subjects, while the 80 mg, 160 mg, and 600 mg dose groups will each enroll 8 subjects. These subjects will be randomly assigned to receive either CX2101A enteric-coated tablets or intravenous remdesivir in a 3:1 ratio.

FE Study for the 300 mg Dose Group: The 300 mg dose group will concurrently conduct a study of food effect on the pharmacokinetics (PK) of CX2101A enteric-coated tablets. This study plans to enroll 14 subjects, who will be randomly assigned to receive either CX2101A enteric-coated tablets (12 subjects) or intravenous remdesivir (2 subjects). In the first period, all 14 subjects will receive a single dose under fasting conditions according to the randomization schedule and will have blood samples collected. The 12 subjects receiving CX2101A enteric-coated tablets will undergo a 7-day washout period with a potential adjustment based on PK data from prior dose groups before proceeding to the second period, where they will receive the drug under fed conditions, complete blood sample collection, and undergo safety assessments.

Part II: Multiple Ascending Dose (MAD) Study MAD Study Design: The MAD study will include 2 dose groups, 100 mg and 300 mg. It plans to enroll 20 healthy adult subjects, with 10 subjects in each dose group. These subjects will be randomly assigned to receive either CX2101A enteric-coated tablets (8 subjects) or CX2101A placebo (2 subjects). The study will involve continuous dosing for 5 days. If the subjects in the first dose group complete their safety assessments and the investigator determines that the dose-escalation termination criteria have not been met, the study will escalate to the next dose level.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Remdesivir and CX2101A in people with COVID-19 and Coronavirus Pneumonia, run by Heronova Pharmaceuticals 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 18 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: finished, as of the sponsor's last update on 6 Mar 2025. 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. Some participants in this study may receive a placebo. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate and severity of treatment-emergent adverse events (TEAEs) (time frame: From day 1 until 5 days after treatment). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 6 Mar 2025.
