ONM-100 to be Featured in Presentation at World Molecular Imaging Congress 2019

– Presentation will highlight the technology of pH-sensitive micelles for tumor-agnostic intraoperative detection of residual tumor-positive margins

– Data from Phase 1 clinical trial for ONM-100 will be shared

SOUTHLAKE, TX—September 5, 2019 – OncoNano Medicine, Inc. announced today that ONM-100 will be featured at the World Molecular Imaging Congress (WMIC), which is being held September 4-7, 2019 in Montreal. The presentation will include results from a Phase 1 clinical trial of ONM-100 as an intraoperative tumor imaging agent as well as information about OncoNano’s pH-sensitive micelle technology platform.

“We are excited to share these promising clinical trial results for ONM-100 at WMIC this year, as many of the world’s foremost experts in molecular imaging will be in attendance,” commented Ravi Srinivasan, Ph.D., CEO of OncoNano. “ONM-100 is designed to take advantage of one of cancer’s simplest biomarkers – acidic pH – to image tumor resection borders regardless of tissue origin and meaningfully improve the accuracy of tumor detection.”

OncoNano’s proprietary pH-sensitive micelles exploit a unique feature of cancer cell metabolism – excess acid. This metabolic defect creates a tumor microenvironment that is acidic relative to normal tissue and enables pH to be used as a stable biomarker of the diseased tissue. OncoNano is developing multiple product candidates using their pH-sensitive micelle platform, which are ultra-sensitive to subtle changes in pH that trigger dissociation when exposed to acidic environments. Thus, the micelle is activated preferentially in the tumor microenvironment to initiate tagging of the tumor but remains intact when exposed to normal physiological pH levels.

Full details of the presentation are listed below:

TITLE:             Metabolic Acidosis in Cancer: A New Strategy Using a pH Transistor Nanoprobe for Fluorescence-Guided Surgery in Humans
PRESENTER:  Pieter J. Steinkamp, M.D., University Medical Center Groningen, the Netherlands
DATE:             September 7, 2019
TIME:             2:30 PM EDT
LOCATION:     Palais des congrès de Montréal, Room 519a

About ONM-100

Surgical tumor resection remains a critical tool of oncology medicine, but detection of tumor borders and residual tumors is notoriously difficult. ONM-100, which utilizes OncoNano’s ultra pH-sensitive micelle platform, is a tumor-agnostic intraoperative tumor imaging agent currently in Phase 2 clinical trials. ONM-100 is designed to be injected intravenously prior to surgery and tags diseased cancerous tissue to provide real-time detection of tumor borders and residual tumors with commercially available imaging equipment. ONM-100 was partially funded for clinical research by the Cancer Prevention and Research Institute of Texas.

About OncoNano Medicine

OncoNano Medicine is developing a new class of pH-activated compounds that digitalize and exploit the variability of pH in disease. pH variability is a proven, simple and effective identifier of diseased tissue providing a foundation for the development of a broad range of highly targeted therapeutics and imaging agents. OncoNano is the first company to advance product candidates using pH as a biomarker for cancer immunotherapy, therapeutic use and intraoperative imaging based on its pH-sensitive micelle technology.
