NAYA Biosciences Announces Publication of New Data for its CD38-targeted Flex-NK™ Bispecific Antibody in the American Society of Hematology's Blood Journal

• Abstract from 2023 American Society of Hematology (ASH) Meeting
• Data demonstrates differentiated profile from DARZALEX® (daratumumab) with best-in-class potential, supports initiation of clinical trials in 2024
• NAYA expects to close its previously announced merger with INVO Bioscience (NASDAQ:INVO) in the first quarter of 2024

AVENTURA, Fla. and SARASOTA, Fla., Dec. 11, 2023 /PRNewswire/ -- NAYA Biosciences Inc. ("NAYA"), a company which has recently signed a definitive merger agreement with INVO Bioscience to establish an expanded, publicly-traded life science company dedicated to increasing patient access to breakthrough treatments in fertility, oncology, and regenerative medicine, today announced that new data for its CD38-targeted Flex-NK™ Bispecific Antibody (NY-338, formerly CYT-338) for the treatment of Multiple Myeloma (MM) was published as an abstract in the 2023 American Society of Hematology's (ASH) meeting supplement of Blood, in the "Multiple Myeloma: Prospective Therapeutic Trials" section.

"NAYA is building a portfolio of differentiated clinical-stage oncology therapeutics, starting with two FLEX-NK™ bispecific antibodies acquired from Cytovia Therapeutics," commented NAYA CEO Dr. Daniel Teper. "We are excited about this new data for our CD38-targeted antibody, which aims to address limitations with the current standard-of-care and offer new options for multiple myeloma patients."

"The synergistic engagement of NK cells through NKp46 greatly enhances the immunotherapeutic effects of FLEX-NK™ bispecific antibodies, reducing NK cell fratricide, maintaining NK cell levels, and enhancing potency including reversal of NK cell dysfunction," added Ola Landgren, MD, PhD, co-author of the abstract and Professor of Medicine, Chief of the Myeloma Division, and Leader of the Experimental Therapeutics Program at the University of Miami's Sylvester Comprehensive Cancer Center. "The data supports initiation of clinical trials to evaluate this promising new therapy and makes it a potential best-in-class anti-CD38 therapeutic for multiple myeloma."

Despite the clinical success of the first anti-CD38 targeted monoclonal antibody, daratumumab, approved for the treatment of multiple myeloma (MM), significant challenges remain such as CD38 antigen loss/internalization and/or natural killer (NK) cell fratricide resulting in resistance to treatment over time. The data presented for NY-338 demonstrates a differentiated profile from daratumumab, with best-in-class potential, and supports the initiation of clinical trials in 2024. Specifically, the conclusions show that the unique NKp46 activation mechanism provided by NY-338 for reducing NK cell fratricide and maintaining NK cell levels together with the enhanced potency including reversal of NK cell dysfunction makes it an attractive best-in-class anti-CD38 therapeutic against MM compared to daratumumab. These results support the development of CYT-338 in both monotherapy and combination with other complementary immunotherapy agents being developed or approved for MM. A first-in-human Phase 1 study targeting patients with relapsed/refractory MM is in development in the U.S.

About NAYA's Proposed Merger with INVO Bioscience

NAYA Biosciences and INVO Bioscience have announced a definitive merger agreement to establish an expanded publicly-traded life science company. Under the terms of the October 23rd merger agreement, pending approval of the transaction by INVO's, Cytovia Therapeutic, Inc. 's, and NAYA's stockholders and subject to key closing conditions, INVO will acquire 100% of the outstanding equity interests in NAYA by means of a reverse triangular merger of a wholly owned subsidiary of INVO with and into NAYA, with NAYA surviving as a wholly owned subsidiary of INVO (the "Merger").  In connection with the Merger, INVO will issue to the stockholders of NAYA newly issued common stock, representing, following such issuance, more than eighty percent (80%) of its issued and outstanding common stock, effectively resulting in a change of control.

Among key closing conditions, INVO must obtain shareholder approval along with certain approvals from existing warrant holders, an estimated $5 million or more (at NAYA's discretion) in interim private financing in INVO at a premium to INVO's market price at time of financing ("Interim PIPE"), and a private offering by the combined company at a target price of $5.00, representing a premium to INVO's last offering of $2.85 per share. The merger target valuation is $12,373,780 for INVO and $90,750,000 for NAYA, based on a target stock price of $5.00 per share. Subject to the Interim PIPE, immediately following the closing of the Merger (but prior to the private offering), the equity holders of NAYA are expected to own approximately 88% of the issued and outstanding common stock of the combined company while the equity holders of INVO are expected to own approximately 12% of the issued and outstanding common stock of the combined company.

The Merger has been unanimously approved by the board of directors of each company and is expected to close in the first quarter (Q1) of 2024.

Glaser Weil Fink Howard Jordan & Shapiro LLP is serving as legal counsel to INVO. Pearl Cohen Zedek Latzer Baratz LLP is serving as legal counsel to NAYA.
