Infusion 51a co-founded company Vivacitas Oncology closes $1 million from DSS as it explores going public

DSS Continues to Grow its Healthcare Segment
through $1M Investment in Vivacitas Oncology

ROCHESTER, N.Y., August 2, 2021 (GLOBE NEWSWIRE) — Document Security Systems,
Inc. (“DSS” or the “Company”) (NYSE American: DSS), a multinational company operating
business segments in blockchain security, direct marketing, healthcare, consumer packaging, real
estate, renewable energy, and securitized digital assets, announced today that its subsidiary, DSS
Biomedical International, Inc. (“DSS Biomedical”), completed a $1 million equity investment in
Vivacitas Oncology, Inc. (“Vivacitas”), a clinical-stage company focused on difficult-to-treat
cancers.

“We continue to demonstrate our commitment to addressing unmet needs in human healthcare
and wellness through key strategic investments,” stated Frank D. Heuszel, CEO of DSS. “With
a rich pipeline of promising assets, Vivacitas provides significant upside potential.”
Vivacitas Oncology Inc. focuses on developing new treatment options to treat cancers resistant
to currently available therapies. It originated in 2015 with the vision of Dr. Joseph Rubinfeld (co-
founder of Amgen) and the endorsement of Infusion 51a, LP (infusion51a.com), an impact
investment fund designed to create value in underappreciated companies from the Precision
Medicine and Biotech industry.

Vivacitas’ lead development candidate (AR-67) is a novel lipophilic next-generation
camptothecin (Topiosomerase-1 enzyme inhibitor) compound with the potential to deliver
improved efficacy and tolerability, employing a proprietary synthesis method.

AR-67 has in vitro, Phase I, and Phase II data in multiple solid tumor types. For instance, it has
demonstrated potential improvement in progression-free survival (6-29 months) in glioblastoma
patients, while significantly reducing severe side effects usually associated with this drug class
(e.g., grade 4 diarrhea). Jeffrey Stephens, founder, CEO and director of Infusion 51a and board
member of Vivacitas Oncology said “Vivacitas Oncology is excited to work with DSS and the
Impact BioMedical team as we continue to execute on our efforts to expand Vivacitas operations
and develop new treatment options for cancer patients worldwide.”
