About this trial

The goal of this clinical trial is to investigate the utility of biomarker tools Extracellular Vesicles (EVs), Patient-derived organoid (PDOs), and PDL1 PET imaging for predicting how participants with recurrent NSCLC respond to standard of care treatment in the advanced/metastatic stages.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Participants must have histologically- or cytologically documented NSCLC who present with recurrent advanced or metastatic disease after initial diagnosis of Stage 1-3 lung cancer

Participants must have been initially diagnosed with operable Stage 1-3 NSCLC and received curative resection ± (neo) adjuvant treatment

Identifiable PDL1 status prior to randomisation

Participants must have biopsy-confirmed recurrence of their initial NSCLC with advanced/metastatic presentation

Disqualifiers

Mixed lung carcinoma (small cell carcinoma and NSCLC), small cell carcinoma, large cell neuroendocrine carcinoma, sarcomatoid carcinoma, or any other histologies that would not benefit from anti-PD1 ± PBCD. If a potential participant has histology other than squamous cell or adenocarcinoma (e.g., mixed histology that is predominantly NSCLC, large cell without neuroendocrine features) but is deemed appropriate for treatment with anti-PD1 ± PBCD, they may be eligible pending discussion with the sponsor.

For participants who received adjuvant therapy that included anti-PD(L)1 Checkpoint inhibitor (CPI) following surgical resection, their last dose of anti-PD(L)1 was <6 months from the date of first 89Zr-durvalumab-PET tracer injection

Participant has known central nervous system (CNS) metastases and/or carcinomatous meningitis that per investigator puts the participant at prohibitive risk to enrol in study

Participant has a known additional malignancy that progressed or required active treatment within the last 2 years. Participant with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with assessments of the study may be included only after discussion with the Medical Monitor

Trial outcomes

Primary outcomes

1

Spearman's rank correlation coefficient between treatment-induced PDL1 modulation in, 1o PDOs and/or extracellular vesicles (EVs) and PET after treatment

The primary endpoint is the correlation between "treatment-induced change in PDL1 in PDOs which will be evaluated as the ratio of PDL1 positive cells before and after treatment using flow cytometry and multiplex immunofluorescence analysis" AND/OR "treatment-induced change in PDL1 in EVs which will be evaluated as the ratio of PDL1 positive cells before and after treatment using flow cytometry and multiplex immunofluorescence analysis" and "changes in PET which will be evaluated as the percentage difference in PDL1-PET standard uptake volume (SUV) uptake in lesions from the baseline to on-treatment" using the formula for Spearman's rank correlation coefficient. The Spearmans rank correlation coefficient can take values from +1 to -1 where a value of +1 indicates a perfect positive association, a value of 0 indicates no association and a value of -1 indicates a perfect negative association.

Time frame
Up to approximately 29 months

Secondary outcomes

1

Spearman's rank correlation coefficient between treatment-induced PDL1 modulation in 1o PDOs and tumour response to anti- Programmed death 1 (PD1) based first line (1L) advanced/metastatic NSCLC treatment

The secondary endpoint is the correlation between "treatment-induced change in PDL1 in PDOs which will be evaluated as the ratio of PDL1 positive cells before and after treatment using flow cytometry and multiplex immunofluorescence analysis" AND "tumor response rate which will be assessed based on RECIST v1.1 per investigator assessment" using the formula for Spearman's rank correlation coefficient. The Spearmans rank correlation coefficient can take values from +1 to -1 where a value of +1 indicates a perfect positive association, a value of 0 indicates no association and a value of -1 indicates a perfect negative association.

Time frame
Up to approximately 34.5 months
2

Spearman's rank correlation coefficient between treatment-induced PDL1 modulation in EVs and tumour response to anti- Programmed death 1 (PD1) based first line (1L) advanced/metastatic NSCLC treatment

The secondary endpoint is the correlation between "treatment-induced change in PDL1 in EVs which will be evaluated as the ratio of PDL1 positive cells before and after treatment using flow cytometry and multiplex immunofluorescence analysis" AND "tumor response rate which will be assessed based on RECIST v1.1 per investigator assessment" using the formula for Spearman's rank correlation coefficient. The Spearmans rank correlation coefficient can take values from +1 to -1 where a value of +1 indicates a perfect positive association, a value of 0 indicates no association and a value of -1 indicates a perfect negative association.

Time frame
Up to approximately 34.5 months
3

Spearman's rank correlation coefficient between treatment-induced PDL1 modulation by PET and radiological tumour response to anti-PD1 based 1L advanced/metastatic NSCLC treatment

The secondary endpoint is the correlation between "changes in PET which will be evaluated as the percentage difference in PDL1-PET standard uptake volume (SUV) uptake in lesions from the baseline to on-treatment" AND "tumor response rate which will be assessed based on RECIST v1.1 per investigator assessment" using the formula for Spearman's rank correlation coefficient. The Spearmans rank correlation coefficient can take values from +1 to -1 where a value of +1 indicates a perfect positive association, a value of 0 indicates no association and a value of -1 indicates a perfect negative association.

Time frame

Number of participants with adverse events (AEs) and serious adverse events (SAEs) following Zirconium-89 (89Zr-durvalumab)-PET radiotracer injection
