ClinConnect Summary

This clinical trial is studying a new medication called YK-029A to see how well it works as a first treatment for patients with advanced non-small cell lung cancer (NSCLC) that has a specific genetic change known as an EGFR exon 20 insertion mutation. The goal is to compare the effectiveness of YK-029A with traditional chemotherapy that includes platinum-based drugs. Participants in the trial will be randomly assigned to receive either YK-029A, which is taken as a pill, or the chemotherapy given through an IV until their cancer worsens or they experience harmful side effects.

To be eligible for the trial, participants must be at least 18 years old and have been diagnosed with advanced NSCLC that is not suitable for surgery. They also need to have a confirmed EGFR exon 20 insertion mutation and adequate tissue samples for testing. Participants can expect to be monitored closely throughout the study and will have regular assessments to check their health and response to treatment. This trial is not yet recruiting, so if you are interested, it’s important to stay updated on when enrollment begins.

Eligibility criteria

• Inclusion Criteria:
• • 1. Male or female adult patients (aged 18 years or older).
• • 2. Histologically or cytologically confirmed nonsquamous cell locally advanced not suitable for definitive therapy, recurrent, or metastatic (Stage IV) NSCLC.
• • 3. Documented epidermal growth factor receptor (EGFR) in-frame exon 20 insertion mutation assessed by a clinical laboratory improvements amendment (CLIA)-certified (China sites) or an accredited (outside of the US) local laboratory.
• • 3、The EGFR exon 20 insertion mutation can be either alone or in combination with other EGFR or human epidermal growth factor receptor 2 (HER2) mutations except EGFR mutations for which there are approved anti-EGFR tyrosine kinase inhibitors \[TKIs\] (ie, exon 19 del, L858R, T790M, L861Q, G719X, or S768I, where X is any other amino acid).
• • 4、Adequate tumor tissue available, either from primary or metastatic sites, for central laboratory confirmation of EGFR exon 20 insertion mutation.
• • 5、At least 1 measurable lesion per RECIST Version 1.1. 6、Life expectancy ≥3 months. 7、Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1. 8、Adequate organ and hematologic function as defined by blood transfusions with a recommended \>/ 14 day washout period.
• Exclusion Criteria:
• • 1. Received prior systemic treatment for locally advanced or metastatic disease, including local administration, such as intra-pleural injection of anticancer medication with the exception noted below.
• • 2. Neoadjuvant or adjuvant chemotherapy/immune therapy for Stage I to III or combined modality chemotherapy/radiation for locally advanced disease is allowed if completed \>6 months before the development of metastatic disease.
• • 3. Received radiotherapy ≤14 days before randomization or has not recovered from radiotherapy-related toxicities.
• • 4. Received a moderate or strong cytochrome P450 (CYP)3A inhibitor or moderate or strong CYP3A inducer within 10 days before first dose of YK-029A.
• • 5. Concurrent EGFR mutations: exon 19 deletion, L858R, T790M, G719X, S768I, or L861Q.
• • 6. Have been diagnosed with another primary malignancy other than NSCLC。
• • 7. Have current spinal cord compression or leptomeningeal disease.
• • 8. Have uncontrolled hypertension. Participants with hypertension should be under treatment on study entry to control blood pressure.
• • 9. Received a live vaccine within 4 weeks before randomization per Summary of product characteristics (SmPCs) for pemetrexed, cisplatin, and carboplatin.
• • 10. As judged by the investigator, any evidence of severe or uncontrolled systemic diseases, including uncontrolled hypertension and active bleeding diatheses (i.e., hemophilia and Von Willebrand disease).
