Clinical Trial Summary

This is a multicenter, randomized, open label, phase III study.

Description:

This is a multicenter, randomized, open label, phase III study assessing the efficacy and safety of Almonertinib combined with or without chemotherapy as an adjuvant treatment in patients with epidermal growth factor receptor (EGFR) mutation positive stage II-IIIA non-squamous NSCLC following complete tumour resection: Eligible patients will be randomized to receive either Almonertinib alone (110mg, po, once daily) or Almonertinib (110mg, po, once daily) plus pemetrexed (500mg/m2, iv) and cisplatin (500mg/m2, iv) or pemetrexed (500mg/m2, iv) plus cisplatin (500mg/m2, iv) in a 3:2:1 ratio.

Eligibility

Inclusion Criteria:

• Any patient who meets all of the following inclusion criteria will qualify for entry

into the study:

1. Male or female, aged at least 18 years.

2. Histologically confirmed diagnosis of primary non small lung cancer (NSCLC) on predominantly non-squamous histology.

3. Brain examination must be done prior to surgery as it is considered standard of care.

6. Providing paraffin embedded section(10-15sheets),wax blocks or fresh frozen tissues.

11. For inclusion in study, patient must provide a written informed consent.

12. =10 weeks between surgery and randomization.

Exclusion Criteria:

• Any patient who meets any of the following exclusion criteria will not qualify for

entry into the study:

1. Treatment with any of the following:

1. Pre-operative or post-operative or planned radiation therapy for the current lung cancer

2. Pre-operative (neo-adjuvant) platinum based or other chemotherapy

3. Prior treatment with neoadjuvant or adjuvant EGFR-TKI at any time

4. Any other anti-tumor treatment for lung cancer(Including proprietary Chinese patent medicine with anti-tumor effects and anti-tumor immunotherapy, etc.)

5. Major surgery (excluding placement of vascular access) within 4 weeks of the first dose of study drug.

6. Treatment with an investigational drug within five half-lives of the compound or any of its related material.

7. Medications that are predominantly CYP3A4 strong inhibitors or inducers or sensitive substrates of CYP3A4 with a narrow therapeutic range within 7 days of the first dose of study drug..

2. Patients who have had only segmentectomies or wedge resections

3. History of other malignancies, except: adequately treated non-melanoma skin cancer, curatively treated in-situ cancer, or other solid tumours curatively treated with no evidence of disease for > 5 years following the end of treatment.

4. Any unresolved toxicities from prior therapy greater than CTCAE Grade 1 at the time of starting study treatment with the exception of alopecia and Grade 2, prior platinum-therapy related neuropathy.

5. Any evidence of severe or uncontrolled systemic diseases, including uncontrolled hypertension and active bleeding diatheses; or active infection including hepatitis B, hepatitis C and human immunodeficiency virus (HIV).

6. Refractory nausea and vomiting, chronic gastrointestinal diseases, inability to swallow the formulated product, or previous significant bowel resection that would preclude adequate absorption of Almonertinib.

7. Any of the following cardiac criteria:

1. Mean resting corrected QT interval (QTc) > 470 ms obtained from 3 electrocardiograms (ECGs), using the screening clinic's ECG machine and Fridericia's formula for QT interval correction (QTcF).

2. Any clinically important abnormalities in rhythm, conduction, or morphology of the resting ECG (e.g., complete left bundle branch block, third-degree heart block, second-degree heart block, PR interval > 250 ms).

3. Any factors that increase the risk of QTc prolongation or risk of arrhythmic events, such as heart failure, hypokalemia, congenital long QT syndrome, family history of long QT syndrome, or unexplained sudden death under 40 years of age in first degree relatives or any concomitant medication known to prolong the QT interval.

8. Past medical history of ILD, drug-induced ILD, radiation pneumonitis which required steroid treatment, or any evidence of clinically active ILD.

9. Inadequate bone marrow reserve or organ function.

10. History of hypersensitivity to any active or inactive ingredient of Almonertinib, or to drugs with a similar chemical structure or class to Almonertinib.

11. Patients who are allergic to pemetrexed or any other ingredients in the preparation, cisplatin or other platinum-containing compounds.

12. Patients with contraindications of pemetrexed and cisplatin.

13. Any severe and uncontrolled ocular disease that may, in the ophthalmologist's opinion, present a specific risk to the patient's safety.

14. Judgment by the Investigator that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions, and requirements.

15. Any disease or condition that, in the opinion of the Investigator, would compromise the safety of the patient or interfere with study assessments.
