**Sapu Nano to Launch Deciparticle™ Platform and Present Clinical Pipeline at BIO-Europe Spring 2026**

AGOURA HILLS, Calif., March 24, 2026 (GLOBE NEWSWIRE) — Oncotelic Therapeutics, Inc. (OTCQB:OTLC) ("Oncotelic", the "Company" or "We" or "Our"), a leader in RNA-based therapeutics, announced today that its subsidiary Sapu Nano will formally introduce its Deciparticle™ nanomedicine platform and present its advancing clinical pipeline at BIO-Europe Spring 2026, where the company has been selected as a Presenting Company.

The presentation will take place at:

● Event: BIO-Europe Spring 2026

● Session: Presenting Company

● Location: Theater A

● Date: March 25, 2026

During the session, Sapu Nano will unveil its proprietary Deciparticle™ platform, a next-generation drug delivery technology engineered to optimize tissue distribution, enhance therapeutic index, and enable intravenous delivery of highly hydrophobic oncology agents.

The company will highlight two lead clinical candidates:

● Sapu003 (Everolimus for Injection)

○ Intravenous formulation of everolimus

○ Designed to overcome limitations of oral exposure and tissue variability

○ Currently in Phase 1 clinical trials

● Sapu006 (Docetaxel for Injection)

○ Advanced formulation of docetaxel leveraging Deciparticle™ technology

○ Aimed at improving safety and efficacy versus conventional docetaxel formulations

○ Entering Phase 1 clinical trials

"Our Deciparticle™ platform represents a major step forward in controlling drug distribution at the tissue level," said Dr. Vuong Trieu, Chief Executive Officer of Sapu Nano. "With Sapu003 and Sapu006 entering Phase 1, we are translating this platform into clinical-stage assets with the potential to significantly improve outcomes in oncology."

The presentation will emphasize:

● Platform-level advantages of Deciparticle™ in sub-20 nm nanomedicine design

● Improved pharmacokinetics and tissue targeting capabilities

● Reduction of formulation-related toxicities associated with conventional excipients

● Broad applicability across multiple hydrophobic drug classes

BIO-Europe Spring is one of the premier global partnering conferences for the life sciences industry, bringing together biotechnology, pharmaceutical, and investment leaders to foster strategic collaborations and advance innovative therapeutics.

Sapu Nano is actively seeking strategic partnerships, co-development opportunities, and regional collaborations to accelerate the clinical development and commercialization of its Deciparticle™ pipeline.
