Details and patient eligibility

About

This study will be performed as a local multicenter, randomized, phase III clinical study. It will compare the adjuvant chemotherapy in Stage IB-IIIA NSCLC with common EGFR mutation (Exon 19 deletion or L858R) who underwent total resection and the Erlotinib-Intercalation adjuvant chemotherapy with the chemotherapy alone. The patients will be randomly assigned to the Intercalation combination chemotherapy regimen and the chemotherapy alone regimen at the ratio of 1:1. The treatment regimen of each arm is as follows.

Sex: All

Ages: 19+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• A screening examination should be implemented within 14 after obtaining the informed consent, and the treatment should be started within 14 days after the randomization of subjects. Subjects who are applicable to all of the following criteria will be eligible for inclusion in this clinical study.

  • Stage IB-IIIA Non-squamous NSCLC (Based on AJCC Version 7 TNM Disease Stages)
  • Surgically complete resection
  • Confirmed with Exon 19 deletion or L858R EGFR mutation
  • Complete recovery from the surgery. The period up to the post-operative randomization can be 3 weeks at minimum up to 8 weeks at maximum.
  • Age to be ≥ 19 years old
  • Patients with Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
  • Patients who are not pregnant or breastfeeding
  • Appropriate functions of bone marrow, liver and kidney, when assessed with the following requirements of the laboratory tests to be conducted within 14 days before the initial dose of the study drug:
  • Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
  • Platelet count ≥ 100 x 109/L
  • Total bilirubin ≤ 1.5 times greater than the upper limit of normal
  • ALT and AST ≤ 2.5 times greater than the upper limit of normal
  • Alkaline phosphatase ≤ 2.5 times greater than the upper limit of normal
  • INR and PTT ≤ 1.5 times greater than the upper limit of normal
  • Appropriate renal function: Serum creatinine ≤ 1.25 × upper limit of normal, or serum creatinine clearance according to Cockcroft-Gault formula(below) ≥50 mL/min

Woman CrCl = (140- age [years old]) x weight (kg) x 0.85 72 x serum creatinine (mg/dL)

Man CrCl = (140- age [years old]) x weight (kg) x 1.00 72 x serum creatinine (mg/dL)

• Patients who are capable of complying with the clinical study protocol and who can take medication orally
• Patient who can hear sufficient explanation and sign on the informed consent form

Exclusion criteria

• Any subject who shows any of the following criteria should be excluded from this clinical study:

  • Patient identified with T790M mutation

  • Treatable with topical treatments (radiotherapy or surgery)

  • Previous treatment to inhibit the human epidermal growth factor receptor (EGFR) (e.g. erlotinib, gefitinib, cetuximab, trastuzumab, etc.)

  • Prior systemic chemotherapy

  • Any prior known hypersensitive reaction to the study agents

  • CTCAE> grade 2 clinically significant active infection

  • Any known infection with Human Immunodeficiency Virus (HIV) or chronic hepatitis type B or type C virus For the patients positive to chronic hepatitis type B or type C virus without elevation of AST/ALT, their inclusion/exclusion will be determined at the discretion of the investigator.

  • Seizures in need of treatment (steroid or antiepileptic treatment)

  • Medical history of interstitial lung disease

  • Medical history of organ allograft within six months

  • Subjects under dialysis

  • A subject diagnosed with another cancer within 3 years before participating in this clinical study (treated carcinoma in situ of the cervix, treated skin basal cell carcinoma, and treated superficial bladder tumors [Ta and Tis] will not be applicable). For surgically completely resected thyroid cancer, it will be determined at the discretion of the investigator.

  • Unstable or any status that would potentially put the subject in danger or that would interfere with compliance of the subject in the clinical study.

  • Treatment with the investigational products other than the one to be used in this clinical study during participation in the clinical study or within 4 weeks prior to participation in the clinical study

  • Pregnant or breastfeeding women. The women at childbearing ages should show negative response to the serum pregnancy test being conducted within 7 days before the initial administration of the study drug. Not only the women at childbearing ages, but also men who give consent to use appropriate contraceptive methods before entering the clinical study and during the period of the clinical study including 30 days after the last dose of the study drug. Post-menopausal women are defined as:

    1. With no menstruation at least for 12 months, at the age >50 years old, or
    2. With no natural menstruation at least for 6 months and the level of follicle-stimulating hormone (FSH) is in the post-menopausal range (>40 mIU/mL) at the age ≤50 years old, or
    3. Bilateral oophorectomy Men and women who are to be enrolled in this clinical study must use appropriate blocking contraceptive methods in prior to and during the clinical study. Appropriate contraceptive methods include implant or combined oral contraceptive agent-utilized hormone contraception, some intrauterine contraceptive device, bilateral tubal ligation, hysterectomy, or vasectomy of the partner. In addition, use of condom is required for the subject or his/her partner.

  • Subjects who are unable to swallow oral medication or with all types of absorption disorders

  • In addition, when the investigator determines it is not adequate to perform the study due to serious systemic diseases.
