Silo Pharma’s SP-26 Ketamine Implant Demonstrates Successful Drug Delivery

Initial indications target fibromyalgia and chronic pain

Loaded and encapsulated drug maintains structural stability as implantable treatment

SARASOTA, FL, Feb. 14, 2024 (GLOBE NEWSWIRE) -- Silo Pharma, Inc. (Nasdaq: SILO) (“Silo” or the “Company”), a developmental stage biopharmaceutical company focused on developing novel formulations and drug delivery systems for traditional therapeutics and psychedelic treatments, today provided a positive update on SP-26, its novel time-released, dose-controlled formulation of ketamine initially targeted for fibromyalgia. A pre-clinical research study is underway involving analytical testing services and small batch proof-of-concept extrusion trials to determine drug release and stability.

In recent testing, SP-26 polymer implants were blended with ketamine hydrochloride (ketamine HCL) in two loadings, 20% and 40%. Measurements and analysis demonstrated that the drug was successfully loaded into the engineered particles to encapsulate the implantable treatment. The structural stability and integrity of both the 20% and 40% loaded implants were maintained, with no leakage, degradation, or discoloration.

“Implantable drug delivery systems like SP-26 may provide sustained drug delivery for prolonged periods of time, which is critical for the treatment of chronic pain conditions,” said Eric Weisblum, CEO of Silo. “We believe the initial testing provided sufficient validation of the delivery system for SP-26 and accordingly, our focus has shifted to testing of the ketamine formulation to measure drug dissolution and time-release action.” 

Mr. Weisblum noted that conventional oral and injectable drugs typically provide peaks of concentration in blood followed by diminished concentration that falls outside of the therapeutic window. Silo believes that implantable drug delivery systems (IDDS) can offer a superior delivery alternative for sustained relief from chronic pain.  

About SP-26

Silo’s SP-26 is a ketamine-based injectable dissolvable implant for the treatment of chronic pain and fibromyalgia. The subcutaneous implant is being designed to safely regulate dosage and time release, of the pain-relieving treatment. If clinically successful, SP-26 could qualify for the FDA’s streamlined 505(b)(2) regulatory pathway for drug approval.
