About this trial

PulmoPrint is a clinical study at UMCG that investigates why some patients with unresectable stage III lung cancer stop responding to immunotherapy after chemoradiation. To do this, a small dose of a fluorescently labeled version of the immunotherapy drug durvalumab is given via an IV drip, after which a camera bronchoscopy is performed to visualize where and how much of the drug actually reaches the tumor and lymph nodes - before the actual durvalumab treatment starts.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Signed informed consent prior to participation in the study.

Age ≥ 18 years.

Histologically or cytologically confirmed unresectable stage III NSCLC.

Completion of concurrent platinum-based CRT

Disqualifiers

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.

Trial outcomes

Primary outcomes

1

In vivo fluorescent signal of malignant lesions (pulmonary nodule or involved lymph node metastasis)

In vivo fluorescent signal of malignant lesions (pulmonary nodule or involved lymph node metastasis) assessed semi-quantitatively (tumor-to-background ratio \[TBR\]/contrast-to-noise ratio) and quantitatively (continuous data by MDSFR/SFF spectroscopy \[pulmonary lesion\] and/or USNB/SFF spectroscopy \[lymph nodes\] measurement). The signal is considered sufficient when a 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.)

Time frame
Assessed directly during the bronchoscopy procedure

Secondary outcomes

1

Correlation of fluorescence signal with IHC

In vivo and ex vivo fluorescence signal, PD-L1 IHC score (assessed according to standard pathology protocols).

Time frame
Up to 2 years
2

Correlation of fluorescence signal with EFS

In vivo and ex vivo fluorescence signal, 1-, 2-and 5-year (long-term exploratory endpoint) event-free survival.

Time frame
Up to 2 years
3

Safety of single durvalumab-680LT injection

Adverse events according to CTCAE v5.0

Time frame
Within 1 week after tracer injection
4

Comparison of the 15 and 25 mg dose durvalumab-680LT

in vivo tumor-to-background ratio of 15 mg versus 25 mg

Time frame
Assessed directly during the bronchoscopy procedure
