Durvalumab and Low-dose PCI vs Durvalumab and Observation in Radically Treated Patients With Stage III NSCLC (NVALT28)

Korábbi kezelés

• Participation in another clinical study with an investigational product during the last 4 weeks.
• Concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study or a study that will not influence the primary and secondary endpoint parameters (e.g. bioimpedance measurements, E-Nose) or the follow-up period of an interventional study. Note: participation in the NVALT31 study (follow up with CT thorax or PET-CT) is allowed
• Patients who receive sequential chemoradiation therapy for locally advanced NSCLC.
• Disease progression after completion of definitive platinum based, concurrent chemoradiation therapy, as proven by a CT scan after end of chemoradiation.
• Any unresolved toxicity CTCAE (v. 5.0) more than grade 2 (i.e. grade 3 or higher) from the prior chemoradiation therapy. Patients with irreversible toxicity that is not reasonably expected to be exacerbated by PCI may be included (e.g. hearing loss) after consultation with the principal investigator.
• Any concurrent chemotherapy, immunotherapy, biologic or hormonal therapy for cancer treatment.
• Active or prior documented autoimmune disease within the past 2 years. NOTE: Patients with vitiligo, Grave's disease, diabetes type I or psoriasis not requiring systemic treatment (within the past 2 years) are not excluded.
• Active or prior documented inflammatory bowel disease (e.g. Crohn's disease, ulcerative colitis).
• History of another primary malignancy within 2 years prior to starting study drug, except for adequately treated basal or squamous cell carcinoma of the skin or cancer of the cervix in situ and the disease under study.
• Prior cranial irradiation is not allowed.
• Except for durvalumab after concurrent chemoradiotherapy, no previous treatment with PD-(L)1-inhibitors is allowed.

• Mixed small cell and non-small cell lung cancer histology.
• History of primary immunodeficiency.
• History of organ transplant that requires therapeutic immunosuppression.
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, active peptic ulcer disease or gastritis, active bleeding diatheses or psychiatric illness/ social situations that would limit compliance with study requirements or compromise the ability of the patient to give written informed consent.
• Known history of tuberculosis, hepatitis B, hepatitis C or Human Immunodeficiency Virus (HIV).
• Any condition that, in the opinion of the investigator, would interfere with evaluation of the study drug or interpretation of patient safety or study results.

Egyéb

• Female patients who are pregnant, breastfeeding or male or female patients of reproductive potential who are not employing an effective method of birth control.

• Patients must sign a study-specific informed consent
• TNM8 stage IIIA, IIIB or IIIC non-small cell lung cancer before start of concurrent chemoradiotherapy (preferentially histology; cytology is allowed)
• Whole body FDG-PET-scan and brain imaging (MRI or CT with iv contrast) before the start of chemoradiotherapy: No distant metastases.
• Additional brain MRI (MRI mandatory) dated within 28 days before randomization: no brain metastases.
• Eligible for durvalumab treatment according to registration label of durvalumab in the Netherlands. Durvalumab has to be given in standard of care. (durvalumab has to be started already before randomization and PCI (i.e. at least one administration of durvalumab has to be given before randomization).
• Treatment completed with concurrent chemoradiation. The last day of chemoradiotherapy should be within 80 days of randomization and randomization should be after start of durvalumab. Any platinum doublet or daily cisplatin regimen that is standard of care in The Netherlands is allowed. No disease progression after chemoradiotherapy (evaluated with CT-thorax and upper abdomen during/after the last dose of chemoradiotherapy and comparison with CT before start of chemoradiotherapy). Consolidation chemotherapy cycles after radiotherapy is not permitted but administration of 1 cycle of chemotherapy prior to concurrent chemo-radiotherapy is acceptable. Where possible, chemotherapy regimens should be given according to National Comprehensive Cancer Network (NCCN) Guidelines or European Society for Medical Oncology (ESMO) Guidelines.
• To be eligible for randomization, patients must have received a total dose of thoracic radiotherapy of 60-66 Gy in 2 - 2.75 Gy per day, oncedaily fractions, or in case of daily cisplatin regimen 60.5-66 Gy in 22-24 fractions. Other radiotherapy schedules are not allowed. Sites are encouraged to adhere to the organ at risk constraints as used in the PACIFIC study as well as the EORTC recommendations for high-dose radiotherapy for lung cancer:
  • Mean lung dose must be \<20 Gy and/or V20Gy must be \<35%
  • Mean oesophagus dose must be \<34 Gy
  • Heart V45Gy \<35% or V30Gy \<30%.
• Proton therapy to the chest is allowed.
• ECOG performance status 0-1 at the time of randomization.
• Evidence of postmenopausal status, or negative urinary or serum pregnancy test for female premenopausal patients.
