Imaging Tumor-infiltrating T-cells in Non-small Cell Lung Cancer

This is an interventional study in 20 patients with resectable non-small cell lung cancer who will receive 2 courses of durvalumab (MEDI4736) in the neo-adjuvant setting, followed by surgery with curative intent.

Experimental imaging procedures include 1) Zr-89-labelled durvalumab (MEDI4736) scan prior to neo-adjuvant treatment to determine accessibility and intra-tumoral distribution of durvalumab (MEDI4736) and 2) (first cohort) injection of ex vivo [111In]-oxine labelled autologous CD8+ T-cells 48 hours prior to surgery, or (second cohort) injection of [89Zr]-Df-crefmirlimab prior to surgery. The scan is scheduled on the day of surgery and after surgery, the resected tumor specimen with ex vivo [111In]-oxine labelled or in vivo [89Zr]-Df-crefmirlimab labelled CD8+ T-cells in situ, is fixated for high-resolution ex vivo imaging on a preclinical U-SPECT scanner and quantitative histopathological analysis, next to standard histopathological evaluation.

Total duration of the study is maximum 42 days (from injection therapeutic dose durvalumab (MEDI4736) to surgery).

• Males: CCL (mL/min) = (Weight (kg) x (140 - Age)) / 72 x serum creatinine (mg/dL)
• Females: CCL (mL/min) = (Weight (kg) x (140 - Age)) / 72 x serum creatinine (mg/dL), multiplied by correction factor 0.85
• Evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal patients. Women will be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses >1 year ago, had chemotherapy-induced menopause with last menses >1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).
• Highly effective contraception for both male and female subjects throughout the study and for at least after durvalumab (MEDI4736) treatment administration intrinsic factor the risk of conception exists

Exclusion criteria

• Inability to lie supine for more than 30 minutes
• Documented previous severe allergic reaction to iodine-based contrast media, despite adequate pre-medication. In case of documented mild to moderate allergic reaction to iodine-based contrast media, patients will receive premedication according to the local protocol, consisting of 25mg prednisolone intravenously 30 minutes prior to iodine-based contrast media administration and 2mg clemastine intravenously just prior to administration.
• Indication for cervical mediastinoscopy according to the local multidisciplinary Thoracic-Oncology meeting
• Participation in another clinical study with an investigational product during the past 6 months
• Concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study
