Pioneering Cost-Effective, Scalable Solutions to Combat the Global Opioid Crisis with Proprietary Air-Driven Delivery Technology

VANCOUVER, British Columbia, Oct. 22, 2025 (GLOBE NEWSWIRE) — via IBN — Branded Legacy, Inc. (OTC:BLEG), a dynamic holding company focused on life sciences and wellness innovation, today announced that its subsidiary, BioLegacy Evaluative Group, has commenced preparation of its FDA Pre-Abbreviated New Drug Application (Pre-ANDA) briefing package for the company’s proprietary intranasal naloxone spray—a key step in advancing its regulatory pathway and commercialization strategy.

The upcoming Target Product Profile (TPP) and Pre-ANDA briefing package mark a pivotal advancement following BioLegacy’s previously announced provisional patent filing for its air-driven intranasal platform, designed to address the global opioid overdose crisis with a next-generation delivery system that is cost-effective, stable, and scalable.

The FDA briefing package outlines:

  • Target Product Profile (TPP): 2 mg and 4 mg naloxone HCl nasal sprays indicated for acute opioid overdose, with a targeted 18–36-month shelf life.
  • CMC Program: Draft Chemistry, Manufacturing, and Controls specifications aligned with ICH guidelines for both drug substance and proprietary device quality.
  • PK Study Protocol: A pivotal 60-subject crossover bioequivalence study benchmarked against Narcan®, evaluating pharmacokinetic parameters including Cmax, AUC, and Tmax.
  • Device & Human Factors Study: Comparative usability assessment involving 20–30 lay participants with a <5% critical-error target, emphasizing accessibility for non-medical users in emergency scenarios.

BioLegacy will seek FDA guidance on:

  1. Confirmation that a single pivotal PK study will satisfy bioequivalence requirements.
  2. Human Factors validation expectations for its custom unitary device.
  3. Specific requirements for extractables/leachables testing on medical-grade polymers.

“This milestone reflects our unwavering focus on developing affordable and scalable overdose-reversal therapeutics,” said Kristian Thorlund, Executive Chair of Branded Legacy, Inc. “Our intranasal platform aims to replicate Narcan® performance while significantly reducing cost and improving global accessibility—helping save lives in the communities that need it most.”

The proprietary air-driven nasal delivery system—previously highlighted in Branded Legacy’s September 30, 2025 announcement—represents a cornerstone technology for BioLegacy’s expanding drug delivery portfolio. The company continues to leverage its state-of-the-art GMP manufacturing facility, unveiled earlier this year, to accelerate formulation development and support regulatory submissions.
