  5. Maximum Plasma Concentration (Cmax) of MR001

    Measured: Predose and at designated timepoints in each cycle for approximately 18 months (each cycle = 2 weeks or 4 weeks)

  6. Half-life (T1/2) of MR001

    Measured: Predose and at designated timepoints in each cycle for approximately 18 months (each cycle = 2 weeks or 4 weeks)

  7. Incidence of Antidrug Antibodies (ADA) to MR001

    Measured: Predose in every 4 cycles for approximately 18 months (each cycle = 2 weeks or 4 weeks)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing MR001, Irinotecan Liposome Injection combined with 5-FU/LV and Nab-paclitaxel in people with Pancreatic Ductal Adenocarcinoma (PDAC), run by Shenzhen Majory Biotechnology Co., Ltd. at 18 sites 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 6 inclusion and 7 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: looking for participants now, as of the sponsor's last update on 6 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Qingshan Xue (+86 13332895357, xueqs@majory.com.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants who experience one or more dose-limiting toxicities (DLTs) (time frame: Approximately 12 months). The study lists 6 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 Nov 2026.
