A Study to Evaluate ONM-100, an Intraoperative Fluorescence Imaging Agent for the Detection of Cancer

A Phase 2a, Single-dose, Open-label Study to Evaluate Diagnostic Performance, Safety & Timing of Postdose Imaging of ONM-100, an Intraoperative Fluorescence Imaging Agent for the Detection of Cancer, in Patients With Solid Tumors Undergoing Routine Surgery

This study is to evaluate diagnostic performance, safety and timing of post-dose imaging of ONM-100, an intraoperative fluorescence imaging agent for the detection of cancer in patients with solid tumors undergoing routine surgery.

Inclusion Criteria:

• Biopsy-confirmed diagnosis of primary or recurrent respective tumor type and scheduled to undergo surgical resection
• Part 1: Biopsy-confirmed diagnosis of head and neck squamous cell carcinoma (HNSCC) or breast cancer
• Part 2: Biopsy-confirmed diagnosis of HNSCC, breast cancer, colorectal cancer, prostate cancer, ovarian cancer, urothelial carcinoma and non-small cell lung cancer.
• Part 3: Stage 2 to 4 HNSCC Including T0 or Tx unknown Primary cancers

Exclusion Criteria:

• Histologically diagnosed by an excisional biopsy procedure
• Tumors at sites of which the surgeon would assess that in vivo intraoperative imaging would not be feasible
• Life expectancy <12 weeks
• Hepatic impairment (Child-Pugh score >5) or significant liver disease including active hepatitis or cirrhosis
