Trial workflow. (A) Subjects were infused with OTL38 4 hours before resection. (B) During resection, real-time IMI was performed using a 5-mm thoracoscope. (C) After resection, suspicious nodules were bisected and imaged ex vivo. (D) All specimens were reviewed by a pathologist (microscopy obtained using a 20× objective).

3. Fig 2
OTL38 accumulates in pulmonary adenocarcinoma and generates fluorescence. Representative subjects 14 (upper panels) and 16 (lower panels) displaying in situ fluorescence. Preoperative (A) computed tomography (CT) and (B) positron emission tomography (PET). Intraoperative (C) brightfield and (D) near-infrared (NIR) merge images. Specimens were reviewed by (E) hematoxylin and eosin (H & E) and (F) FRα immunohistochemistry (IHC) (microscopy obtained using a 20× objective).

Deep tumors display fluorescence upon bisection. In representative subject 2, ex vivo fluorescence after tumor bisection: (A) preoperative computed tomography (CT) demonstrates tumor 1.6 cm from pleural surface; (B) ex vivo near-infrared imaging with no tumor fluorescence (arrow); and (C) ex vivo near-infrared imaging with fluorescence after bisection.

5. Fig 4
Intraoperative molecular imaging with OTL38 identifies synchronous nodules in subject 19. A representative nodule is displayed in (A) brightfield and (B) near-infrared (NIR) merge view. (C) The nodule was pulmonary adenocarcinoma by hematoxylin and eosin (H&E), with (D) with FRα expression by immunohistochemistry (IHC) (microscopy obtained using a 20× objective).
