説明
Inclusion Criteria:
- Signed informed consent prior to participation in the study.
- Age ≥ 18 years.
- Histologically or cytologically confirmed unresectable stage III non-small cell lung cancer.
- Completion of concurrent platinum-based chemoradiotherapy
- Eligibility for adjuvant durvalumab per standard of care.
- At least one tumor lesion or involved lymph node accessible by bronchoscopy or endoscopic/endobronchial ultrasound, suitable for biopsy/fine-needle aspiration (FNA) and fluorescence measurement.
- Eastern Cooperative Oncology Group (ECOG) performance status 0-2.
- Patient is considered fit to undergo a research bronchoscopy (with or without addition of endobronchial ultrasound; including propofol sedation or general anesthesia if either is indicated).
Exclusion Criteria:
- Known history of infusion reactions to durvalumab, other anti-PD-L1 antibodies, or other monoclonal antibodies, according to the patient's medical history.
- Contraindication for bronchoscopy or endoscopic/endobronchial ultrasound (if applicable), including severe uncorrectable coagulopathy, pre-existing severe respiratory insufficiency, or any other clinical reason as judged by the investigator.
- Medical or psychiatric conditions compromising the patient's ability to provide informed consent, according to the treating physician.
- Pregnancy or breastfeeding. A negative pregnancy test must be available for women of childbearing potential on the day of tracer administration.
- Use of an investigational medicinal product within 30 days prior to tracer administration.

実験的:Fluorescence molecular imaging during bronchoscopy with durvalumab-680LT at dose of 15 mg
Patients will receive an intravenous administration of 15 mg durvalumab-680LT before the bronchoscopy procedure. The bronchoscopy will start with high-definition white light bronchoscopy, followed by fluorescence molecular bronchoscopy to visualize the fluorescence signal and MDSFR-SFF spectroscopy to quantify the fluorescence signal in vivo. * MDSFR, multi-diameter single-fiber reflectance spectroscopy; SFF, single-fiber fluorescence spectroscopy |

実験的:Fluorescence molecular imaging during bronchoscopy with durvalumab-680LT at dose of 25 mg
Patients will receive an intravenous administration of 25 mg durvalumab-680LT before the bronchoscopy procedure. The bronchoscopy will start with high-definition white light bronchoscopy, followed by fluorescence molecular bronchoscopy to visualize the fluorescence signal and MDSFR-SFF spectroscopy to quantify the fluorescence signal in vivo. * MDSFR, multi-diameter single-fiber reflectance spectroscopy; SFF, single-fiber fluorescence spectroscopy |

In vivo fluorescence signal of malignant lesions (pulmonary nodule and/or involved lymph node metastases)
時間枠:Assessed directly during the bronchoscopy procedure
|
In vivo fluorescence signal of malignant lesions (pulmonary nodule and/or involved lymph node metastases) assessed semi-quantitatively (tumor-to-background ratio [TBR]/contrast-to-noise ratio) and quantitatively (continuous data by multi-diameter single-fiber reflectance (MDSFR)/single-fiber fluorescence (SFF) spectroscopy [pulmonary lesion] and/or Ultrasound-guided needle biopsy (USNB)/SFF spectroscopy [lymph nodes] measurement).
The signal is considered sufficient when a tumor-to-background ratio (TBR) greater than 2 is achieved, assessed both by the fluorescence camera system and by the spectroscopy system.
(The comparison of the fluorescence signal between lesion and background is a supportive exploratory analysis intended to characterize signal distribution; it does not constitute evidence of diagnostic or comparative performance.)
