Positive data supports the continued advancement of FDA Investigational New Drug (IND)- enabling development program

SARASOTA, FLA., June 23, 2026 (GLOBE NEWSWIRE) — Silo Pharma (Nasdaq: SILO) (“Silo” or “the Company”), a developmental-stage biopharmaceutical company focused on novel therapeutics and drug delivery systems, today announced that it has confirmed the physical, chemical and microbiological stability of its investigational soft-mist intranasal prophylactic, SPC-15, through nine months of real-time testing. The stability data demonstrates that SPC-15’s formulation maintains physical, chemical, and microbiological integrity over nine months at long term and six months at accelerated conditions.

The stability program was conducted under long-term and accelerated storage conditions aligned
with requirements for investigational new drug (IND)-enabling chemistry, manufacturing, and controls (CMC) documentation. Data showed that SPC-15’s formulation and device remained within predefined specifications for assay, impurities, pH, and microbiological quality through nine months, and the product remained in trend for predefined key device spray performance tests. Six-month accelerated stability data was consistent and aligned with long term data.

“The positive stability data support continued advancement of our IND-enabling development program and contribute to the manufacturing information required in an IND submission for a first-in-human Phase 1 clinical study,” said Eric Weisblum, CEO of Silo Pharma. “This important milestone validates our adherence to current Good Manufacturing Practice (cGMP) standards.”
