Clinical Trial Summary

This is a prospective, open, single-center, single-arm phase II clinical study with common EGFR-sensitive mutations (Ex19del and L858R) identified in the central laboratory.To evaluate the efficacy and safety of adjuvant Osimertinib therapy in completely resected stage I non-squamous non-small cell lung cancer (NSCLC) with high-risk factors (solid and/or micropapillary component ≥10%, and/or airway spread).


Description:

Patients will be tested for the status of EGFR-sensitive mutations prior to enrollment and confirmed positive by central laboratory testing.The surgically removed tumor foci will be confirmed by central laboratory pathologic examination for their pathological subtypes, solid and/or micropapillary components ≥10%, and/or STAS positive. These patients had undergone complete resection of the tumor, and 65 patients who met the criteria for inclusion were enrolled to receive Osimertinib. Patients had to be enrolled and given Osimertinib within 10 weeks of complete resection.The dose of Osimertinib in this study was 80 mg once a day and the planned duration of treatment was 3 years (156 weeks). Patients will be evaluated for safety and efficacy at baseline, at week 12, and every 12 weeks thereafter until completion or termination of treatment. Patients were followed up every 24 weeks to 5 years (264 weeks) and annually thereafter for disease recurrence. Overall survival (OS) was observed every 24 weeks for 5 years (264 weeks) after disease recurrence and annually thereafter.The primary endpoint of the study was 3-year DFS rate. Disease-free survival (DFS) should be calculated from the date of entry on Osimertinib to the date of disease recurrence or death. After the primary analysis (3-year DFS rate), patients' survival status will be followed up according to the simplified study plan (OS analysis period) until the final OS analysis data is available. In the event of disease recurrence, patients will be re-staged and all sites of recurrence of NSCLC will be recorded. It will be up to the doctor to decide what treatment the patient will receive after a relapse;and cancer treatment after recurrence will be documented.Taken together, all primary, secondary, and exploratory endpoints in this study strongly describe the overall benefit of adjuvant Osimertinib in a population of patients with high-risk EGFRm+ stage I NSCLC who have been surgically completely resected.

Irreversible surgical sterilization recorded by hysterectomy, bilateral oophorectomy or bilateral salpingectomy, but not tubal ligation;Male subjects must be willing to use barrier contraception. Exclusion Criteria: 1. Exposure to other antitumor therapies before enrollment; 2. Patients who only received segmental resection and wedge resection; 3. History of other malignancies, other than non-melanoma skin cancer, carcinoma in situ or other solid tumors that have been effectively treated, and the treating physician has determined that there is no evidence of disease recurrence for 5 years after treatment; 4. Evidence of any severe or uncontrolled systemic disease, including uncontrolled hypertension and active bleeding, any condition that the investigator considers to be detrimental to patient participation in the study or to adherence to the protocol, or active infections including hepatitis B, hepatitis C, and human immunodeficiency virus (HIV). Omission requirement for screening chronic diseases; 5. Any of the following cardiac criteria: - QTc values obtained using screening clinic ECG machines mean resting corrected QT interval (QTc) > 470 milliseconds from 3 electrocardiogram (ECG) tests, - Any abnormalities in rhythm, conduction, or morphology of a clinically significant resting ECG, such as left bundle branch block, third degree heart block, and second degree heart block. - Any factors that increase the risk of prolonged QTc or arrhythmia events, such as heart failure, hypokalemia, congenital long QT syndrome, sudden unexplained death under 40 years of age in a first-degree relative or any concomitant medication known to prolong the QT interval. 6. Any evidence of prior history of interstitial lung disease, drug-induced interstitial lung disease, radiation pneumonia requiring steroid treatment, or active interstitial lung disease; 7. Lack of adequate bone marrow reserve or organ function (demonstrated by any of the following laboratory values: absolute neutrophil count <1.5×10?/L;Platelet count <100×10?/L;Hemoglobin <90 g/L;Alanine aminotransferase > 2.5 ULN; Aspartate aminotransferase >2.5 times ULN;Total bilirubin > 1.5 ULN;Serum creatinine >1.5 ULN with creatinine clearance <50 mL/min [as measured or calculated by Cockcroft and Gault formulas] - creatinine clearance only needs to be confirmed when creatinine >1.5 ULN); 8. History of hypersensitivity to active or inactive excipients of Osimertinib or drugs with similar chemical structures or classes to ocitinib; 9. Uncontrolled nausea and vomiting, chronic gastrointestinal illness, inability to swallow formulated drugs, or prior major bowel resection that prevents adequate absorption of Osimertinib; 10. Any evidence of corneal injury confirmed by ophthalmic examination through slit lamp evaluation; 11. The patient is pregnant or nursing; 12. History of allergy to ocitinib active or inactive excipients or drugs similar in chemical structure or class to Osimertinib; 13. If the patient is unlikely to comply with study procedures, restrictions, and requirements, the investigator judges that the patient should not participate in the study.

Primary 3-year DFS rate DFS is defined as time from randomization to disease recurrence (determined by CT or MRI scan and/or pathologic disease on biopsy) or death (from any cause) by investigator assessment. 3-year DFS rate is Disease-Free Survival at 3 Years. From date of randomisation up to approximately 5 years
Secondary DFS DFS is defined as time from randomization to disease recurrence (determined by CT or MRI scan and/or pathologic disease on biopsy) or death (from any cause) by investigator assessment. From date of randomisation up to approximately 10 years
Secondary 3-year OS rate Defined as the percentage of patients alive at 3 years, respectively, estimated from a Kaplan Meier plot of OS at the time of the primary analysis From date of randomization up to approximately 5 years
Secondary 5-year OS rate Defined as the percentage of patients alive at 5 years, respectively, estimated from a Kaplan Meier plot of OS at the time of the primary analysis From date of randomization up to approximately 5 years
Secondary OS OS is defined as the time from the date of randomisation until death due to any cause. From date of randomization up to approximately 10 years
Secondary Safety and tolerability in overall population AEs graded by CTCAE version 5.0 From date of randomisation up to approximately 10 years
Secondary health-related quality of life and Symptoms (HRQoL) Change from baseline will be calculated for each domain and summary scale at each scheduled post-baseline assessment. The SF-36 includes eight domains: Physical Functioning (PF); Role Limitations-Physical (RP), Vitality (VT), General Health Perceptions (GH), Bodily Pain (BP), Social Function (SF), Role Limitations-Emotional (RE), and Mental Health (MH) and two summary scores: The Physical Component Summary (PCS) and Mental Component Summary (MCS). Final scores for each scale range from 0-100 with higher scores indicating better health. Measured by SF-36 Questionnaire at baseline, 12 week,and then every 24 weeks until study complete, disease recurrence or other discontinuation criteria met, up to approximately 5 years.
