A Study of 5 Years of Adjuvant Osimertinib in Completely Resected Epidermal Growth Factor Receptor Mutation (EGFRm) Non-small Cell Lung Carcinoma (NSCLC)

Korábbi kezelés

• Major surgery (including primary tumour surgery, excluding placement of vascular access) within 4 weeks prior to the first dose of study drug.
• Participants currently receiving medications or herbal supplements known to be strong inducers of CYP3A4 (at least 3 weeks prior to first dose).
• Refractory nausea and vomiting, chronic gastrointestinal diseases, inability to swallow the formulated product, or previous significant bowel resection that would preclude adequate absorption of osimertinib.

Más betegség

• Past medical history of interstitial lung disease (ILD), drug-induced ILD, radiation pneumonitis that required steroid treatment, or any evidence of clinically active ILD.

Laborértékek

• Treatment with any of the following:
  • Pre-operative or post-operative or planned radiation therapy for the current lung cancer.
  • Pre-operative (neo-adjuvant) platinum-based or other chemotherapy.
  • Any prior anti-cancer or immunological therapy, including investigational therapy, for treatment of NSCLC other than standard platinum-based doublet post-operative adjuvant chemotherapy.
  • Prior treatment with neoadjuvant or adjuvant EGFR tyrosine kinase inhibitor (TKI).
• Any of the following cardiac criteria:
  • Mean resting corrected QT (QTc) interval > 470 msec, obtained from 3 electrocardiograms (ECGs).
  • Any clinically important abnormalities in rhythm, conduction, or morphology of resting ECG.
  • Any factors that increase the risk of QTc prolongation or risk of arrhythmic events.
  • Heart failure, congenital long QT interval (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 and cause Torsades de Pointes (TdP).

Életkor

• 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 before the start of study intervention.

Egyéb

• Participants who have had only segmentectomies or wedge resections.
• Inadequate bone marrow reserve or organ function.
• Women who are breastfeeding.

• Male or female aged at least 18 years.
• Histologically confirmed diagnosis of primary NSCLC on predominantly non-squamous histology.
• Magnetic Resonance Imaging (MRI) or contrast computed tomography (CT) scan of the brain.
• Participants must be classified post-operatively as Stage II, IIIA, or IIIB on the basis of surgical pathologic criteria.
• Confirmation by the local laboratory that the tumour harbours one of the two common EGFR mutations (Ex19del, L858R), either alone or in combination with other EGFR mutations including de novo EGFR mutation resulting in substitution of threonine with methionine at amino acid position 790 in exon 20 of EGFR (T790M) or uncommon EGFR mutations G719X, S768I, and L861Q, either alone, in combination with each other, or in combination with other uncommon EGFR mutations (excluding all exon 20 insertions) (Uncommon EGFRm Cohort).
• Complete surgical resection of the primary NSCLC is mandatory. All gross disease must have been removed at the end of surgery. All surgical margins of resection must be negative for tumour.
• Complete recovery from surgery and standard post-operative therapy (if applicable) at start of study intervention.
• World Health Organisation Performance Status of 0 to 1.
• Female participants must be using highly effective contraceptive measures, and must have a negative pregnancy test prior to start of dosing if of childbearing potential.
• Male participants must use effective barrier contraception.
