Aspyrian Therapeutics Announces The Presentation Of Clinical Data Of Its Investigational Therapy Rm-1929 Demonstrating Significant Anti-Cancer Response In Recurrent Head And Neck Cancer Patients Who Have Failed All Existing Treatment Options
SAN DIEGO, April 27, 2017 /PRNewswire/ -- Aspyrian Therapeutics, Inc., a biotechnology company developing precision-targeted cancer therapies based on the proprietary Photoimmunotherapy (PIT) platform, today announced that findings from an ongoing clinical trial of its proprietary investigational compound, RM-1929, were presented at the American Head & Neck Society meeting, April 27, in San Diego.
The data presented are from a multicenter trial of PIT with RM-1929 for patients with recurrent head and neck squamous cell carcinoma that cannot be satisfactorily treated with surgery, radiation or platinum chemotherapy. The data are from seven patients enrolled at Thomas Jefferson University, Philadelphia, PA. The Principal Investigator, Dr. David Cognetti, and his team described the clinical outcomes in patients treated with repeated cycles of PIT with RM-1929. Each treatment consisted of a single drug infusion of RM-1929, followed by light activation of the drug at the tumor at 24-hour post infusion. If persistent disease was present at 4 weeks, the patient could progress into a subsequent treatment cycle. The investigators noted, "Targeted photoimmunotherapy using a conjugate of cetuximab and IR700 dye is safe and well tolerated and led to evidence of tumor necrosis at the treatment site in 7/7 (100%) patients. No skin photosensitivity or normal tissue toxicity noted. Four out of 7 (57%) patients had durable clinical response to the treatment without progression of disease."
"It is truly extraordinary how dramatic and rapid the tumor response to RM-1929 Photoimmunotherapy has been on cancers that have been recurrent and resistant to all therapies, while also being well tolerated by the patients. None of the patients have had any light sensitivities or other systemic side effects, which is a major limitation of other traditional cancer treatment modalities." said Dr. David Cognetti, M.D., Associate Professor, Co-Director, Jefferson Center for Head and Neck Surgery, Sidney Kimmel Cancer Center at Thomas Jefferson University, Philadelphia, PA.
"This is a remarkable treatment outcome for head and neck cancer patients who have failed all previous standard of care therapies and have no viable therapeutic options available to them." said Dr. Merrill Biel, M.D. Ph.D., Chief Medical Officer of Aspyrian. "These first in human clinical data support the potential for RM-1929 Photoimmunotherapy to uniquely provide a viable option to control this disease while preserving normal healthy tissues in the head and neck area that are so critical to maintaining the patient's quality of life and we look forward to the ongoing clinical trial results."
"In less than two years after initiating clinical studies of RM-1929, we have rapidly gained a good understanding of the safety and anticancer potential of Photoimmunotherapy with RM-1929. Given the significant results so far, we are fully committed to drive this therapy to the market as fast as possible and we intend to initiate the first registration trials in early 2018." said Miguel Garcia-Guzman, Ph.D., President and CEO at Aspyrian. "We intend to develop Photoimmunotherapy with RM-1929 as a single agent and as a combination treatment to provide the best possible outcomes for recurrent head and neck cancer patients, both in the first-line and-second line settings. In addition, we expect to initiate further phase 2 proof-of-concept studies in other EGFR expressing cancer types sometime in the second half of 2018. I congratulate our outstanding team at Aspyrian and our excellent clinical collaborators, particularly Dr. Cognetti, for their exceptional work and commitment to provide cancer patients with better options to conquer their disease".
About RM-1929
RM-1929, a conjugate of Cetuximab and IRDye 700DX®, targets epidermal growth factor receptor (EGFR), a cancer antigen expressed in multiple types of solid tumors, including head and neck squamous cell carcinomas, esophagus, lung, colon, and pancreas. This first-in-class therapy uses an antibody conjugate to precisely target cancer cells after which it is locally activated with red light to elicit rapid anti-cancer responses. The dual specificity resulting from local activation of a tumor-selective conjugate promises to deliver oncologists the ability to achieve locoregional tumor control with minimal damage to surrounding healthy tissues and structures.
RM-1929 is an investigational compound that is not approved for any use in any country.
