Non Small Cell Lung Cancer
Conditions
Brief summary
This is a randomized, controlled, double-blind, multicenter, phase III clinical study.
Detailed description
This is a randomized, controlled, double-blind, multicenter, phase III clinical trial, evaluating the efficacy and safety of HS-10296 compared to gefitinib in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor sensitizing mutations (EGFRm+) who have not received systemic therapy. Patients are randomly assigned to an HS-10296 treatment group or a gefitinib treatment group at a ratio of 1:1 and receive a once-daily oral dose of HS-10296 or gefitinib, in order to compare the efficacy and safety of the two different treatment regimens.
Interventions
Drug: HS-10296 110 mg/55 mg + placebo The initial dose of HS-10296 110 mg once daily can be reduced to 55 mg once daily under specific circumstances. A cycle of treatment is defined as 21 days of once daily treatment. Number of Cycles: as long as patients are continuing to show clinical benefit, as judged by the Investigator, and in the absence of discontinuation criteria.
Drug: Gefitinib 250 mg + placebo The initial dose of Gefitinib 250 mg once daily cannot be reduced. A cycle of treatment is defined as 21 days of once daily treatment. Number of cycles: as long as patients are continuing to show clinical benefit, as judged by the Investigator, and in the absence of discontinuation criteria.

Eligibility
Inclusion criteria
Inclusion Criteria: Any patient who meets all of the following inclusion criteria will qualify for entry into the study: 1. Provision of informed consent prior to any study specific procedures, sampling and analyses. 2. Male or female, age at least 18 years. 3. Pathologically confirmed locally advanced or metastatic NSCLC (e.g. this may occur systemic recurrence after prior surgery for early stage disease or patients may be newly diagnosed with stage IIIB/IV disease). Patients must be treatment-naïve for locally advanced or metastatic NSCLC. Prior adjuvant and neo-adjuvant therapy is permitted (chemotherapy, radiotherapy, investigational agents) provided all other entry criteria are satisfied. 4. The tumour harbours one of the 2 common EGFR mutations known to be associated with EGFR-TKI sensitivity (Ex19del, L858R), either or in combination with other EGFR mutations assessed by central testing using tumour tissue sample or blood sample. 5. A WHO performance status equal to 0-1 with no deterioration over the previous 2 weeks and a minimum life expectancy of 12 weeks. 6. At least 1 lesion that has not previously been irradiated, that has not been chosen for biopsy during the study screening period, and that can be accurately measured at Baseline as ≥ 10 mm in the longest diameter (except lymph nodes, which must have short axis ≥ 15mm) with computerized tomography (CT) or magnetic resonance imaging (MRI), whichever is suitable for accurately repeated measurements. If only one measurable lesion exists, it is acceptable to be used (as a target lesion) as long as it has not been previously irradiated and baseline tumour assessment scans are done at least 14days afar the screening biopsy is performed. 7. Females should be using adequate contraceptive measures throughout the study; should not be breastfeeding at the time of screening, during the study and until 3 months after completion of the study; and must have a negative pregnancy test prior to start of dosing if of childbearing potential or must have evidence of non-childbearing potential by fulfilling 1 of the following criteria at Screening: 1. Postmenopausal defined as age more than 50 years and amenorrheic for at least 12 months following cessation of all exogenous hormonal treatments. 2. Women under 50 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more, following cessation of exogenous hormonal treatments, and with luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels in the postmenopausal range for the laboratory. 3. Documentation of irreversible surgical sterilization by hysterectomy, bilateral oophorectomy, or bilateral salpingectomy, but not by tubal ligation. 8. Male patients should be willing to use barrier contraception (i.e., condoms). 9. For inclusion in study, patient must provide a written informed consent. \-
