Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Diagnosis

to evaluate feasibility of 68Ga-tilmanocept PET/CT for SLN mapping in patients with stage I-II high/high-intermediate risk endometrial cancer

Secondary objectives 1

  1. - To investigate the correlation between SLN detection rate and anatomical location of SLNs with preoperative 68Ga-tilmanoceptPET/CT versus intraoperative ICG with NIR fluorescence; - To assess pathological status of the SLNs: tumour negative, macrometastasis (diameter >2.0 mm), micrometastasis (diameterbetween 0.2 and 2.0 mm) or isolated tumour cells (diameter <0.2 mm or individual tumour cells); - To investigate adverse events related to SLN mapping with 68Ga-tilmanocept PET/CT up to one hour post-PET/CT (graded byCommon Terminology Criteria for Adverse Events (CTCAE) v5.0).

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 1

  1. - Clinical FIGO 2012 stage I-II high/high-intermediate risk endometrial cancer; - Scheduled for robot-assisted full pelvic and para-aortic staging; - Age ≥18 years and able to provide informed consent.

Exclusion criteria 1

  1. - Pregnancy or current breastfeeding (in women at a ferile age with a possibility of prenancy, confirmation by a pregnancy test is current standard of care); - Prior severe allergic reaction to iodine; - Severe renal insufficiency (stage 3 or 4); - Clinical or radiological evidence of metastatic disease.

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Primary endpoint is the feasibility of the SLN procedure using 68-Ga tilmanocept PET/CT in patients with high/high-intermediate riskendometrial cancer. The feasibility is assessed by the SLN detection rate of 68Ga-tilmanocept PET/CT. The SLN detection rate of PET/CT is defined as the detection of a PET-avid node.

Secondary endpoints 2

  1. - To investigate the correlation between SLN detection rate and anatomical location of SLNs with preoperative 68Ga-tilmanoceptPET/CT versus intraoperative ICG with NIR fluorescence; - To assess pathological status of the SLNs: tumour negative, macrometastasis (diameter >2.0 mm), micrometastasis (diameterbetween 0.2 and 2.0 mm) or isolated tumour cells (diameter <0.2 mm or individual tumour cells);
  2. Adverse events related to SLN mapping with 68Ga-tilmanocept PET/CT up to one hour post-PET/CT (graded by CommonTerminology Criteria for Adverse Events (CTCAE) v5.0).
