About

The purpose of this study is to compare the effectiveness of YK-029A as first-line treatment with that of platinum-based chemotherapy in participants with locally advanced or metastatic non-small cell lung cancer (NSCLC) whose tumors has epidermal growth factor receptor (EGFR) exon 20 insertion mutations.

Participants will be randomly assigned to one of the two treatment groups YK-029A group or Platinum-based chemotherapy group.

Participants will receive YK-029A orally and pemetrexed/cisplatin or pemetrexed/carboplatin via vein until the participants experience worsening disease (PD) as assessed by blinded independent review committee (IRC), intolerable harmful effects or another discontinuation criteria.

Full description

The drug being tested in this study is called YK-029A. YK-029A is being tested to evaluate the efficacy as a first line treatment compare with platinum-based chemotherapy in the participants with locally advanced or NSCLC whose tumors harbor EGFR exon 20 insertion mutations.

The study will enroll 350 patients. Participants will be randomly assigned to one of the two treatment groups-YK-029A Group (Arm A) or Platinum-based Chemotherapy Group (Arm B).

The participants will be administered with YK-029A orally in arm A and pemetrexed/cisplatin or pemetrexed/carboplatin intravenously (IV) in arm B until the participants experience progressive disease (PD) as assessed by blinded independent review committee (IRC), intolerable toxicity or another discontinuation criteria.

Participants in the chemotherapy group should not be allowed to cross over to treatment with YK-029A after IRC-assessed PD is documented. Randomized treatment with YK-029A or platinum-based chemotherapy may be continued after PD, at the discretion of the investigator and with the sponsor's approval, if there is still evidence of clinical benefit.

This multi-center trial will be conducted in China . The overall time to participate in this study is until 3 years after the last participant is randomized. Participants will make multiple visits to the clinic and will be followed for survival, subsequent anticancer therapy, subsequent disease assessment outcome until disease progression on a subsequent anticancer therapy, and participant-reported health status (EORTC QLQ-C30 and EORTC QLQ-LC13) for 3 years after the last participant is randomized in the study and 30 days after the last dose of study drug for safety follow-up.

Inclusion criteria

Male or female adult patients (aged 18 years or older).
Histologically or cytologically confirmed nonsquamous cell locally advanced not suitable for definitive therapy, recurrent, or metastatic (Stage IV) NSCLC.
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

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.
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.
Received radiotherapy ≤14 days before randomization or has not recovered from radiotherapy-related toxicities.
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.
Concurrent EGFR mutations: exon 19 deletion, L858R, T790M, G719X, S768I, or L861Q.
Have been diagnosed with another primary malignancy other than NSCLC。
Have current spinal cord compression or leptomeningeal disease.
Have uncontrolled hypertension. Participants with hypertension should be under treatment on study entry to control blood pressure.
Received a live vaccine within 4 weeks before randomization per Summary of product characteristics (SmPCs) for pemetrexed, cisplatin, and carboplatin.
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).
