About this study

Official title: An Apen-label, Multicenter Phase II Study to Evaluate the Efficacy and Safety of BEBT-109 in Patients With EGFR Exon 20 Insertion Mutations in Locally Advanced or Metastatic Non-Small Cell Lung Cancer

This study is an open-label, multicenter Phase II trial, planning to enroll 200 subjects, using BEBT-109 capsules as monotherapy, aimed at evaluating the efficacy and safety of BEBT-109 capsules in subjects with Epidermal Growth Factor Receptor (EGFR) exon 20 insertion mutations in locally advanced or metastatic Non-Small Cell Lung Cancer (NSCLC).

Read the detailed description

This study is designed with two cohorts, each comprising approximately 100 subjects. Cohort 1 includes subjects with EGFR exon 20 insertion mutations in NSCLC who have failed or are intolerant to at least one systemic chemotherapy and have not received third-generation EGFR (Tyrosine Kinase Inhibitor) TKI therapy. Cohort 2 includes subjects with EGFR exon 20 insertion mutations in NSCLC who have failed or are intolerant to at least one systemic chemotherapy and have experienced Progressive Disease after receiving standard-dose third-generation EGFR TKI therapy.Subjects receive BEBT-109 capsules treatment with a dosage of 120mg bid (twice a day), and each 28-day period constitutes a cycle. In case of intolerance during the treatment, dose adjustments can be made according to the adjustment plan.

Each subject's study process includes three phases: the screening period, the treatment period, and the post-treatment follow-up period. The screening period can last up to 28 days.During the treatment period, tumor assessments are conducted every 8 weeks (±7 days). If the initial response is Partial Response (PR) or Complete Response (CR ), a confirmation assessment for efficacy is required between 4-6 weeks. Subjects can continue to receive study medication until Progressive Disease (PD), death, intolerable toxicity occurs, or the subject withdraws informed consent (whichever comes first). After discontinuing treatment, subjects will enter the post-treatment follow-up period, receiving efficacy follow-ups every 8 weeks (±7 days) (until tumor progression or other anti-tumor treatments are administered) and survival follow-ups every 3 months (±7 days).

When a subject experiences the first instance of Progressive Disease, if the investigator believes that continued use of the study medication may still be beneficial, the subject is allowed to continue receiving study medication until imaging indicates no clinical benefit.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing BEBT-109 Capsule in people with Non-Small Cell Lung Cancer and EGFR Exon 20 Insertion Mutation, run by BeBetter Med Inc at 2 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 10 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: looking for participants now, as of the sponsor's last update on 26 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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 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 Kegang Jiang, Master (+86-18664786382, kjiang@bebettermed.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

ORR (time frame: Every 8 weeks,assessed up to 24 months.). The study lists 2 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 26 Nov 2024.
