Squamous cell carcinoma of the larynx and hypopharynx

The primary aim of this study is to determine the feasibility of using intraoperative fluorescence-imaging (FLI) to identify laryngeal and hypopharyngeal cancer during total laryng(opharyng-)ectomy. A tumor-to-Background ratio (TBR) of >1.5 is defined as 'feasible'.

Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Efficacy, Dose response, Safety

The primary aim of this study is to determine the feasibility of using intraoperative fluorescence-imaging (FLI) to identify laryngeal and
hypopharyngeal cancer during total laryng(opharyng-)ectomy. A tumor-to-Background ratio (TBR) of >1.5 is defined as 'feasible'.

Secondary objectives 5

  1. Sensitivity, specificity and positive predictive value of FLI
  2. The intraoperative change in surgical management based on FLI
  3. FLI of excised cervical lymph nodes
  4. Influence of previous radiotherapy on the FLI performance
  5. Adverse events and toxicity after intravenous injection with cRGD-ZW800- 1

Conditions and MedDRA coding

Squamous cell carcinoma of the larynx and hypopharynx

  6. Patients with renal insufficiency (defined as eGFR<60)
  7. Patients with previous kidney transplantation or a solitary functioning kidney
  8. Immuno-compromised patients who do not have the ability to respond normally to an infection due to an impairedor weakened immune system, caused by either a pre-existing disease or concomitant medications
  9. Patients using medications that may significantly impair renal function (i.e. NSAIDs, particularly COX- 2inhibitors), that cannot be paused during the course of the study
  10. Patients with ASA classification of 4 or higher
  11. Patients with measured QTc of 500 ms or higher at screening

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. The primary study endpoint of WP-1 is the tumor-to-background ratio (TBR) of laryngeal or pharyngeal tumours with fluorescence imaging after cRGD-ZW800-1 administration. The primary endpoint of WP-II is the number of clear resection margins
