Building on Their Innovative mRNA Vaccine Program, Ocean Biomedical, Inc. and Aesther Healthcare Acquisition Corp. (NASDAQ: AEHA) Recently Announced Business Combination to Support the Discovery of a New Class of Antimalarial Drugs.

• Upon closing of their proposed Business Combination, Ocean Biomedical will be a wholly owned subsidiary of Aesther Healthcare Acquisition Corp. and will change its name to Ocean Biomedical, Inc., and is expected to be listed on NASDAQ under the symbol, “OCEA”.

Providence, RI and New York, NY, Sept. 22, 2022 (GLOBE NEWSWIRE) — Ocean Biomedical and Aesther Healthcare Acquisition Corp. (“Aesther”) (NASDAQ: AEHA) recently announced business combination, once closed, will further Ocean Biomedical’s work on the discovery of a whole new class of antimalarial drugs which target PfGARP and kill malaria parasites.

In recent studies published and reviewed in Nature, Ocean Biomedical’s Scientific Co-founder, Dr. Jake Kurtis, identified the parasite protein PfGARP as a target of human antibodies which kill up to 100% of parasites in vitro by inducing apoptosis or parasite programmed cell death – this discovery forms the basis of Ocean Biomedical’s lipid encapsulated mRNA-based vaccine and therapeutic monoclonal antibodies.

Ocean’s breakthrough approach targets the blood-stage portion of the malaria lifecycle – the stage responsible for all clinical disease and death, and therefore has the potential of significantly greater efficacy compared with vaccines targeting other stages.

Now, Dr. Kurtis’ team has developed a family of small molecule drugs which bind to PfGARP at nanomolar concentrations and kill parasites by inducing apoptosis. They have demonstrated these drugs: 1) are highly specific for PfGARP binding, 2) are non-toxic in multiple in vitro and in vivo systems, 3) have excellent pharmacokinetic properties, and 4) rapidly clear parasitemia in animal models. Ocean Biomedical and Aesther Healthcare are proud to add this significant program to our pipeline.

Malaria caused by infection with Plasmodium parasites is the greatest single-agent killer of children on the planet, killing approximately 627,000 individuals last year. Artemisinin-based drug therapy remains the mainstay of treatment, but the spread of parasites resistant to this family of compounds threatens recent progress achieved by antimalarial campaigns and underscores the urgent need to identify new anti-malarial drugs. Surprisingly, WHO malaria treatment protocols do not reserve novel classes of antimalarials specifically for the treatment of severe malaria- a central tenet of antimicrobial stewardship- due to the paucity of available alternative drug classes.

“Small molecule drugs targeting PfGARP have an impressive ability to induce parasite cell death and represent a novel class of anti-malarials, which we so desperately need as artemisinin resistant parasites spread,” commented Dr. Jake Kurtis, Chair of Pathology and Laboratory Medicine at the Warren Alpert Medical School Brown University; Scientific co-founder.

“Falciparum malaria is a leading cause of death in children world-wide and our global malaria treatment strategy relies almost exclusively on artemisinin-based drugs. The recent emergence of high grade resistance to artemisinin is an existential threat to this strategy and mandates the development of novel classes of antimalarials. We are thrilled to announce our discovery of a novel class of antimalarials which have to potential to save hundreds of thousands of lives” said Dr. Chirinjeev Kathuria, co-founder and Executive Chairman. 

Suren Ajjarapu, Chairman and CEO of Aesther, commented, “Aesther is honored to be part of the exciting discovery announced by Ocean Biomedical today. We look forward to working with Ocean to bring these therapies to patients. This discovery, coupled with the powerful approach in our malaria vaccine program, will lead to long term shareholder value growth and appreciation.”
