A Phase III Study to Assess the Effects of Almonertinib Following Chemoradiation in Patients With Stage III Unresectable Non-small Cell Lung Cancer

Korábbi kezelés

• History of interstitial lung disease (ILD) prior to chemoradiation.
• Any unresolved toxicity Common Terminology Criteria for Adverse Events (CTCAE) ≥ Grade 2 from the prior chemoradiation therapy.

Más betegség

• Mixed small cell and non-small cell lung cancer histology.
• Symptomatic pneumonitis following chemoradiation.
• 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)).
• Refractory nausea, vomiting, or chronic gastrointestinal diseases, or inability to swallow the study drug that would preclude adequate absorption of Almonertinib.
• History of hypersensitivity to any active or inactive ingredient of Almonertinib or to drugs with a similar chemical structure or class to Almonertinib.
• Any severe and uncontrolled ocular disease that may, in the ophthalmologist's opinion, present a specific risk to the patient's safety.
• Any disease or condition that, in the opinion of the investigator, would compromise the safety of the patient or interfere with study assessments.

Laborértékek

• Treatment with any of the following:
  • Prior treatment with any prior chemotherapy, radiation therapy, immunotherapy or investigational agents for NSCLC outside of that received in the definitive setting for Stage III disease (chemotherapy and radiotherapy in SCRT and CCRT regimens is allowed for treatment of Stage III disease). Patients who have previously undergone surgery for stage I or stage II NSCLC can be enrolled. If neoadjuvant or adjuvant therapy (non-EGFR tyrosine kinase inhibitor) is used, neoadjuvant or adjuvant therapy needs to be completed for at least half a year (6 months) before enrollment.
  • Prior treatment with EGFR-TKI therapy.
  • Major surgery (including primary tumor surgery, excluding placement of vascular access) within 4 weeks of the first dose of study drug.
  • Patients currently receiving (unable to stop use prior to receiving the first dose of study treatment) medications or herbal supplements known to be strong inducers and inhibitors of cytochrome CYP3A4 (at least 7 days prior to receiving the first dose of study drug).
  • Treatment with an investigational drug within five half-lives of the compound or any of its related material.
• Any of the following cardiac criteria:
  • 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).
  • Any clinically important abnormalities in rhythm, conduction, or morphology of the resting ECG (e.g., PR interval > 250 ms).
  • Any factors that increase the risk of QTc prolongation or risk of arrhythmic events, such as heart failure or any concomitant medication known to prolong the QT interval.
  • Left ventricular ejection fraction (LVEF) ≤ 40%.

Életkor

• History of other malignancies, excluding fully treated non-melanoma skin cancer, in-situ cancer, or other solid tumors that hadn't recurrent for > 5 years following the end of treatment.

Egyéb

• Inadequate bone marrow reserve or organ function.
• 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.

• Provision of informed consent before any study-specific procedures, sampling and analyses.
• Male or female, age at least 18 years.
• Histologically or cytologically confirmed diagnosis of primary non-small lung cancer (NSCLC) on predominantly non-squamous pathology who present with locally advanced, unresectable (Stage III) disease (according to AJCC 8th edition lung cancer classification). Recommended by not required: In addition to obvious cT4 disease, lymph node status N2 or N3 should be confirmed by intrabronchial ultrasound, mediastinoscopy or thoracoscopy biopsy, and under the condition of no biopsy or negative biopsy, the whole body screening of 18F-Fluro-deoxyglucose positron emission tomography (PET)or contrast agent-enhanced computed tomography (CT) to confirm.
• The tumor harbours one of the two common EGFR mutations known to be associated with EGFR-TKI sensitivity (Ex19Del, L858R), either alone or in combination with other EGFR mutations including T790M, assessed by cobas® EGFR Mutation Test (Roche Diagnostics) or Xiamen AmoyDx EGFR (ADx-ARMS, Super-ARMS method) kit in site or central laboratory.
• Patients must have received either concurrent chemoradiation or sequential chemoradiation including at least 2 cycles of platinum based chemotherapy and a total dose of radiation of 60 Gy ±10% (54 to 66 Gy).
• Chemoradiation must be completed ≤6 weeks prior to randomization.
• Patients must not have had disease progression during or following definitive platinum-based, chemoradiation therapy.
• A WHO performance status of 0-1 with no deterioration over the past 2 weeks and a minimum life expectancy of 12 weeks.
• Female patients should be using adequate contraceptive measures and should not be breastfeeding at the screening period, during the study, and six months after the last dosing of study. A pregnancy test should be done before first dosing unless having evidence of non-child-bearing potential.
• Male patients should be willing to use barrier contraception (condoms)
