About this study

Official title: A Two-phase, Multicenter, Open Phase I Study of BEBT-607 Tablets in The Treatment of Advanced or Metastatic Solid Tumors With KRAS G12C Mutation

This is a two-phase, multicenter, open phase I clinical study, with phase Ia as dose escalation phase and phase Ib as dose expansion phase, to evaluate the safety tolerability and pharmacokinetic characteristics of BEBT-607 tablets in patients with advanced or metastatic solid tumors associated with KRAS G12C mutation. To evaluate the efficacy of BEBT-607 tablets in the treatment of patients with advanced or metastatic solid tumors with KRAS G12C mutation, and to determine the recommended dose (RP2D) for Phase II clinical trials of BEBT-607 tablets in patients with advanced or metastatic solid tumors with KRAS G12C mutation.

Read the detailed description

Phase Ⅰa:

The dose escalation plan is to carry out about 6 dose levels. The initial dose of BEBT-607 tablets is set at 100mg/ day, and the subsequent dose groups are first increased by 100%. If a case of drug-related grade 2 non-hematological toxicity or grade 3 hematological toxicity is found and does not reach DLT, the subsequent dose groups are increased by 50%. If one case of dose limiting toxicity(DLT) is found and does not reach maximum tolerated dose(MTD ), the subsequent dose group is increased by 33%（Doses are rounded to multiples of 100mg）.The single dose is 1/2 of the total daily dose, and the single administration phase is administered once a day, and the continuous administration phase is administered twice a day (only once on the 28th day of the first cycle).

Phase Ⅰb:

According to the pharmacokinetics, safety and preliminary efficacy results of phase Ⅰa dose escalation phase, one to three cohorts with target dose or tumor species are selected for dose extension trial, and a maximum of 30 subjects are enrolled in each cohort. The subjects receive BEBT-607 tablets twice a day, orally before breakfast and before dinner, respectively. There is a treatment cycle every 28 days (On days 1 and 28 of the first cycle, the drug is administered only once before breakfast). The study process for each subject consisted of three phases: screening, treatment, and follow-up. During treatment, participants are required to undergo safety checks every four weeks from the first dose, tumor assessments every eight weeks, safety follow-up at the end of treatment 28 days after the last dose, efficacy follow-up every eight weeks, and survival follow-up every three months.

Participants will need to understand the requirements and risks of the trial, sign an informed consent form, accept the dosing regimen required by the trial protocol, and follow the investigator's guidance.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BEBT-607Tablets in people with Advanced or Metastatic Solid Tumor and KRAS G12C Mutation, run by BeBetter Med Inc 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 20 inclusion and 21 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 18 Aug 2026. 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?

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?

MTD (time frame: Phase Ⅰa:Day 2 after the single dose phase, day 1, day 15, and day 28 of the first cycle of the continuous dose phase，assessed up to 4 weeks.). 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?

On the ClinicalTrials.gov record for NCT06117371.

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 18 Aug 2026.
