Study Details

Study Description

Brief Summary

This is a non-randomized, open-label, single-center, safety and imaging feasibility study of Pegsitacianine, an intraoperative fluorescence imaging agent.

Detailed Description

This is a non-randomized, open-label, single-center, safety and imaging feasibility study of Pegsitacianine, an intraoperative fluorescence imaging agent.

The main purpose of this study is to investigate whether Pegsitacianine can be used to image head and neck cancers as well as unknown primary cancer of the head and neck 6-100 hours post dose in patients undergoing routine surgery for biopsy, evaluation, detection or removal of their primary cancer.

The study consists of two Parts.

  • Part 1 will be performed in a single dose of 1 mg/kg given such that Pegsitacianine fluorescence can be used to image primary tumors in patients with HNSCC undergoing routine surgery at 6-100 hours, and if needed at an alternate imaging schedule post dose.

  • Part 2 will be performed in a single dose of 1 mg/kg given such that Pegsitacianine fluorescence can be used to image primary tumors in patients with unknown primary cancer of the head and neck (UPC) at 6-100 hours, and if needed at an alternate imaging schedule post dose.

Intervention Model Description:
In Part 1 the single dose of 1 mg/kg of pegsitacianine given 6-100 hours prior to surgery will be used to image primary tumors in patients with HNSCC to evaluated to verify the diagnostic performance of pegsitacianine fluorescence imaging for detecting primary tumors and metastatic lymph nodes. In Part 2, pegsitacianine the single dose of 1 mg/kg of given 6-100 hours prior to surgery will be used to in patients with unknown primary cancer of the head and neck. These patients typically undergo exam under anesthesia with a laryngoscopy as well as panendoscopy for identifying the source of the metastatic cancer found in the cervical nodes. Subjects for Part 2 may begin dosing at any time during Part 1 thus the two parts can run concurrently.In Part 1 the single dose of 1 mg/kg of pegsitacianine given 6-100 hours prior to surgery will be used to image primary tumors in patients with HNSCC to evaluated to verify the diagnostic performance of pegsitacianine fluorescence imaging for detecting primary tumors and metastatic lymph nodes.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Part 1 - Cohort A

In Part 1 the single dose of 1 mg/kg of pegsitacianine given 6-100 hours prior to surgery will be used to image primary tumors in patients with HNSCC to evaluated to verify the diagnostic performance of pegsitacianine fluorescence imaging for detecting primary tumors and metastatic lymph nodes.

Drug: Pegsitacianine
Infusion of the Pegsitacianine-Intraoperative fluorescence imaging

Active Comparator: Part 2 - Cohort B

In Part 2, pegsitacianine the single dose of 1 mg/kg of given 6-100 hours prior to surgery will be used to in patients with unknown primary cancer of the head and neck. These patients typically undergo exam under anesthesia with a laryngoscopy as well as panendoscopy for identifying the source of the metastatic cancer found in the cervical nodes. The diagnostic performance of pegsitacianine fluorescence imaging for detecting primary tumors and metastatic lymph nodes in these patients will be evaluated. All the available data to date will be used to decide the additional tumor type(s), number of patients per tumor type, and number of Group(s) to be enrolled.

Drug: Pegsitacianine

Outcome Measures

Primary Outcome Measures

  1. Diagnostics performance and safety of 1 mg/kg Pegsitacianine in patients with HNSCC [5 years]

    Pegsitacianine fluorescence from in vivo and excised tissues will be imaged using intraoperative and post-operative NIR cameras and will be correlated with the histopathological confirmation of tumor and normal tissues to determine Pegsitacianine's diagnostic performance. Patient safety will be assessed for 10 days (±48 hours) post dose. All patients will be monitored for vital signs and physical examination pretreatment and at various time points up to Day 6 (±24 hours). All patients will be monitored for comprehensive metabolic panel (CMP) and complete blood count (CBC) with differentials pretreatment and at various time points up to Day 10 (±48 hours). All patients will be monitored for TEAEs, and concomitant medication use from the start of dosing up to Day 10 (±48 hours). TEAEs will be followed closely during the study to identify any potential DLTs

  2. Diagnostics performance and safety of 1 mg/kg Pegsitacianine in patients with UPC [5 years]

    Pegsitacianine fluorescence from in vivo and excised tissues will be imaged using intraoperative and post-operative NIR cameras and will be correlated with the histopathological confirmation of tumor and normal tissues to determine Pegsitacianine's diagnostic performance. Patient safety will be assessed for 10 days (±48 hours). All patients will be monitored for vital signs and physical examination pretreatment and at various time points up to Day 6 (±48 hours). All patients will be monitored for comprehensive metabolic panel (CMP) and complete blood count (CBC) with differentials pretreatment and at various time points up to Day 10 (±48 hours). All patients will be monitored for TEAEs, and concomitant medication use from the start of dosing up to Day 10 (±48 hours). TEAEs will be followed closely during the study to identify any potential DLTs

Secondary Outcome Measures

  1. Pegsitacianine fluorescence imaging in HNSCC, UPC primary cancers that are HPV positive and HPV negative [5 years]

    Pegsitacianine fluorescence from in vivo and excised tissues will be imaged using intraoperative and post-operative NIR cameras and will be correlated with the histopathological confirmation of tumor and normal tissues to determine Pegsitacianine's diagnostic performance. Assessment of use of Pegsitacianine for intra-operative imaging of HNSCC, UPC and metastatic lymph nodes will include quantification of intraoperative and postoperative fluorescence signals from histology confirmed tumor and normal tissues, calculation of TBR and diagnostic performance. Feasibility determination will be based on a combined assessment of intraoperative in vivo and ex vivo fluorescent signals together with ex vivo examinations (histological examination, NIR flatbed scanning).
