SAN FRANCISCO, CA / ACCESSWIRE / May 29, 2024 / Jaguar Health, Inc. (NASDAQ:JAGX) ("Jaguar") today announced that the company's out-licensing agreement with Magdalena Biosciences, Inc. ("Magdalena"), the joint venture formed by Jaguar and Filament Health Corp. (OTCQB:FLHLF) (CBOE CA:FH) (FSE:7QS) to develop novel, natural prescription medicines derived from plants for mental health indications, has been expanded to cover ethnobotanical know-how related to development of a prescription drug compound (the "Botanical Drug Candidate") from a specified medicinal plant for possible schizophrenia and psychoses indications and for development with potential corporate partners.

"We are very happy to have executed the out-licensing arrangement with Magdalena related to the Botanical Drug Candidate," said Lisa Conte, Jaguar's president and CEO. "The amended license agreement between Jaguar and Magdalena stipulates that Jaguar will receive 10% of all upfront payments, milestone payments, and similar payments received by Magdalena as part of any business development partnerships Magdalena enters for the Botanical Drug Candidate, excluding commercial milestones and R&D reimbursements, up to a defined cap amount. The amended license agreement also stipulates that Jaguar will receive royalties on annual net sales of the Botanical Drug Candidate by Magdalena and any sublicensees, if the Botanical Drug Candidate receives FDA approval and is commercialized, with the royalty percentage increasing if annual net sales surpass a defined dollar amount."

The U.S. schizophrenia market is projected to grow to $8.06 billion by 2030, according to a market research report by Market Research Future.¹

Neuropsychopharmacology profile analysis shows the Botanical Drug Candidate demonstrates antipsychotic activity and has a mechanism of action distinct from FDA-approved therapies for schizophrenia and other mental conditions that present psychotic symptoms. Magdalena, which is approximately 40-percent owned by Jaguar, is focused on advancing plant-based innovation for patients and on identifying the next generation of plant-based first-in-class agents for treatment of mental health conditions. The Botanical Drug Candidate has a long history of use by traditional healers and may have the potential to be the first in a new class of plant-based antipsychotic compounds.

"Our team has always recognized and valued the unique and powerful knowledge Indigenous and traditional peoples have about plants, ecosystems, and healing compounds," said Steven King, Ph.D., Jaguar's chief sustainable supply and ethnobotanical research officer and an Advisor to Magdalena. "Jaguar's library of approximately 2,300 medicinal plants from tropical regions - developed over three decades by medicinal tropical scientific strategy team advisors, including ethnobotanists, physicians, pharmacologists, chemists, and experts in neuropharmacology from around the world - comprises a unique asset to drive drug discovery. The plant collection was assembled by teams of experts who conducted primary, first-hand field investigations and plant identification work in rainforest regions around the globe in addition to gathering data about traditional medicinal uses of plants from shamans and other Indigenous healers."

Schizophrenia, the most serious form of psychosis, is a chronic, disabling mental illness that affects approximately one percent of the U.S. population.² It is estimated that up to 34% of patients with schizophrenia fail to respond to currently available treatments.³ Psychotic symptoms can also be present in other mental illnesses, including depression, bipolar disorder, dementia, and borderline personality disorder.

About Botanicals Drugs

Botanicals drugs are defined by the U.S. Food and Drug Administration (FDA) as "products from plant materials, algae, macroscopic fungi, and combinations thereof." Many botanical drugs have a long history of safe use in traditional medicines, which may be documented and reviewed in scientific literature. Existing scientific literature on safety may accelerate the safety review process for a botanical drug, reducing the scope and financial burden for extensive safety studies. The FDA has established guidance on botanical drug development and recognizes the complexity of botanical drugs. Additionally, botanicals drugs, by virtue of their complexity, have the added benefit of being difficult to genericize. Hence there are often multiple opportunities for creating ‘trade-secrets,' as well as novel patents around a botanical drug substance, its processing, its formulation, and so forth.
