Clinical Trial Summary

This is a prospective, randomised, uncontrolled phase II clinical trial planned to include 84 subjects with metastatic lung adenocarcinoma that had progressed after first- or second-line treatment with Osmertinib, who were randomly assigned to trial group 1 and trial group 2, and were given Furmonertinib 160 mg and 240 mg once/day, orally, respectively, with efficacy evaluated every 6 weeks until disease progression, intolerable toxic side effects, or Subjects voluntarily withdrew informed consent.

Eligibility

Inclusion Criteria:

• Previous genetic testing for a definite EGFR-sensitive mutation and imaging-confirmed extracranial lesion progression after first-line treatment with Osimertinib; or previous genetic testing for a definite T790M mutation and imaging-confirmed extracranial lesion progression after second-line treatment with Osimertinib.

• Pre-existing clinical benefit after treatment with Osimertinib, including CR, PR, SD (duration >6 months);

• Patients with at least 1 measurable lesion according to the criteria for evaluating the efficacy of solid tumors (RECIST 1.1)

• Normal functioning of major organs

• Patients with non-lung adenocarcinoma, including squamous lung cancer or mixed histological types

• Progression of imaging-confirmed extracranial lesions after prior Osimertinib treatment with accessible treatment options after genetic testing

• Patients with symptomatic brain metastases, meningeal metastases or spinal cord compression

• Any unrecovered CTCAE > grade 1 toxicity reaction following prior Osimertinib treatment at the start of study drug therapy

• Other malignant tumors within 5 years or history of other malignant tumours; except effectively controlled basal cell carcinoma of the skin, carcinoma in situ of the uterine cervix, ductal carcinoma in situ of the breast, papillary carcinoma of the thyroid, superficial bladder tumors, etc.

• History of interstitial pneumonia with previous diagnosis

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Adverse Events	The number of patients with adverse events and the severity according to CTCAE v5.0.	From the start of study drug to 30 days after the last dose of study drug
Primary	Objective Response Rate(ORR)	Objective Response Rate (ORR) (per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) using Investigator assessments) is defined as the number (%) of patients with response	Analysis will occur when PFS maturity is observed at approximately 12 months from the first patient begin study treatment
Secondary	Progression-free survival (PFS)	Progression-free survival (PFS) using Investigator assessment as defined by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1). Progression-free survival (PFS) is defined as the time from beginning of study treatment until the date of objective disease progression or death (by any cause in the absence of progression), regardless of whether the patient withdraws from randomized therapy or receives another anti-cancer therapy prior to progression. Patients who have not progressed or died at the time of analysis will be censored at the time of the latest date of assessment from their last evaluable Response Evaluation Criteria in Solid Tumors (RECIST) assessment.	The primary analysis of Progression-free survival (PFS) based on investigator assessment will occur when PFS maturity is observed at approximately 12 months after the first patient begin study treatment
Secondary	Disease Control Rate (DCR)	Disease control rate (DCR) is defined as the percentage of subjects who have a best overall response of Complete Response (CR) or Partial Response (PR) or Stable Disease (SD) by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) as assessed by the Investigator.	Analysis will occur when PFS maturity is observed at approximately 12 months from the first patient begin study treatment
Secondary	Duration of Response (DoR)	Duration of Response is defined as the time from the date of first documented response until the date of documented progression or death in the absence of disease progression.	Duration of Response analysis will occur when Progression-free survival (PFS) maturity is observed at approximately 12 months from the first patient begin study treatment
