- License expands collaboration with Florida State University to evaluate castanospermine for Powassan virus disease, tick-borne encephalitis, alpha-gal syndrome, and post-treatment Lyme disease
- Agreement builds on Company's expertise in vector-borne diseases and complements ongoing development of tafenoquine for babesiosis
- Company continues to evaluate multiple regulatory pathways for castanospermine while prioritizing prescription drug development
WASHINGTON, July 08, 2026 (GLOBE NEWSWIRE) -- 60 Degrees Pharmaceuticals, Inc. (NASDAQ: SXTP; SXTPW) (the “Company” or “60 Degrees Pharma”), a pharmaceutical company focused on developing new medicines for vector-borne disease, today announced that it has entered into an exclusive option agreement with the Florida State University Research Foundation (FSURF) covering intellectual property related to the therapeutic development of castanospermine for multiple tick-borne diseases.
Under the agreement, 60 Degrees Pharma has an exclusive option to negotiate an exclusive U.S. license for patented technology and associated know-how relating to the use of castanospermine in the fields of Powassan virus disease, tick-borne encephalitis, alpha-gal syndrome, and post-treatment Lyme disease. The agreement also provides the Company with an evaluation period to develop a commercialization strategy and supporting development plan.
Castanospermine is a naturally occurring iminosugar found in Australian Chestnut (Castanospermum australe). The compound has demonstrated broad antiviral and immunomodulatory activity in preclinical studies. There is substantial human safety experience from clinical trials with celgosivir, a pro-drug that converts almost completely to castanospermine after oral administration.
“This agreement reflects our belief that castanospermine may have its greatest long-term value as the basis for innovative prescription medicines addressing important unmet needs in tick-borne diseases,” said Geoff Dow, Chief Executive Officer of 60 Degrees Pharma. “The option agreement gives us the flexibility to advance a focused development strategy while leveraging our existing expertise in vector-borne infectious diseases.”
The Company recently met with the U.S. Food and Drug Administration to discuss its New Dietary Ingredient Notification for use of Australian Chestnut Extract in a dietary supplement. Following those discussions, the Company is re-evaluating its regulatory strategy for the dietary supplement opportunity while prioritizing development programs where castanospermine may provide greater clinical and commercial value.
