About this study

Official title: A Phase 1, Open-label, Single-arm Study to Evaluate the Pharmacokinetics and Safety of MRTX849 in Chinese Patients With Advanced Solid Tumors With KRAS G12C Mutation

This is a phase 1, open-label, single-arm study in Chinese patients with unresectable, locally advanced or metastatic solid tumor with KRAS G12C mutation, for which treatment with curative intent is not available.

Patients must have a documented KRAS G12C mutation determined by tissue or liquid-based local testing.

The PK profile of MRTX849 in Chinese patients will be evaluated after administration of a single and repeat oral doses of 600 mg BID. In the PK lead-in period, blood samples will be collected pre-dose and up to 96 hours post a single oral dose of 600 mg MRTX849. Following this lead-in period, patients will start the dosing regimen of 600 mg BID orally, and blood samples will be collected pre-dose and up to 12 hours after multiple doses of MRTX849 600 mg BID on Cycle 1 Day 8 (C1D8).

Safety including AEs, ECGs, laboratory parameters and vital signs of each patient will be monitored throughout the conduct of the study.

Disease response and progression will be evaluated in accordance with Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MRTX849Drug

    Approximately 18-24 patients to ensure at least 12 PK evaluable patients.

    Subjects will be administered a single oral dose of 600 mg MRTX849 in PK lead in D1, and will start the dosing regimen of 600 mg BID orally from C1D1.

Study groups in NCT05263986
Study groupRoleWhat they receive
Assigned InterventionsExperimentalIn the 5-day PK lead-in period, patients will receive a single oral dose of 600 mg MRTX849 on Day 1 and there will be no drug administration in the subsequent 4 days. Following the PK lead-in period, patients will receive MRTX849 600 mg BID (an interval of approximate 12 hours between 2 doses) orally in 3-week cycles until disease progression, unacceptable AEs, patient refusal, or death. Dosing schedules may be adjusted depending on safety results.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MRTX849 in people with Advanced or Metastatic Solid Tumor, run by Zai Lab (Shanghai) Co., Ltd. at 8 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 22 inclusion and 27 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 27 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 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 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?

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?

Main PK parameters: Cmax (time frame: Approximately 2 weeks after dose initiation). The study lists 15 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 27 Feb 2023.
