• Magdalena aiming to submit Investigational New Drug (IND) application in early 2025 to the FDA for a next-generation psychoactive prescription drug candidate for potential mental health indications such as ADHD and schizophrenia, with 1-2 additional IND applications filed in 2025

SAN FRANCISCO, CA / ACCESSWIRE / October 10, 2024 / Jaguar Health, Inc.(NASDAQ:JAGX) today announced that Dr. Karen Brunke, Jaguar's EVP of Corporate and Business Development and Acting CEO of Magdalena Biosciences, Inc. (Magdalena), the joint venture recently 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, is presenting on Wednesday, October 16, 2024 at 10:15 a.m. PDT at the BIO Investor Forum, which takes place October 15-16 in San Francisco, California.

"I very much look forward to providing an overview of Magdalena at BIO Investor Forum and meeting with potential partners and investors at the event," Dr. Brunke said. "We expect Magdalena's lead botanical drug candidate, MB2500, to soon be IND-enabled and ready to enter the clinic for the first indication: attention deficit hyperactivity disorder (ADHD). We're also very excited about MB2500's potential in a second indication, where it may serve as a first-ever treatment for the cognitive deficit that goes untreated in schizophrenia - which is a huge unmet medical need. Schizophrenia is a disease of cognitive deficit, a deficit which appears as much as a decade before onset of psychotic symptoms,¹ but no approved drug currently exists to treat cognitive deficit in schizophrenia patients."

MB2500 is derived from a well characterized plant that has been in use by local populations for centuries, has been shown to have both neuroprotective and cognitive enhancing properties, but has never been put through the rigorous clinical testing required for FDA approval. One or two more additional Magdalena botanical drug candidates for mental health indications are planned to be IND-enabled in 2025.

ADHD, a $25 billion global market,² is a neurodevelopmental disorder characterized by the core symptoms of hyperactivity, inattentiveness, and impulsivity, and there is a growing need for safer ADHD treatments. Schizophrenia is a chronic, disabling mental illness that affects approximately one percent of the U.S. population.³ The global schizophrenia market is projected to grow to $13.41 billion by 2032, according to a market research report by Market Research Future.⁴

Magdalena, which is currently approximately 40-percent owned by Jaguar, is focused on advancing plant-based innovations for patients and on identifying the next generation of plant-based first-in-class agents for treatment of mental health conditions. Botanical drug candidates have a long history of use by traditional psychiatrists and may have the potential to serve as a new class of plant-based psychoactive drugs which are safe for daily at-home dosing.

An independent partnering event dedicated to showcasing drug development programs that are ready for partnering or venture funding, the BIO Investor Forum is focused on treating patients by accelerating the progress of new therapeutic technologies into commercialization. The event features two days of panel discussions on policy, business, financing, and R&D along with company presentations, and one-on-one partnering meetings.

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, botanical 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.

The Growing Market for Medicines Derived from Psychoactive Plants

According to the World Health Organization, one in four people in the world will be affected by mental or neurological disorders at some point in their lives. Around 450 million people currently suffer from such conditions, placing mental disorders among the leading causes of ill-health and disability worldwide. Among children, ADHD is the most common psychiatric disorder, disrupting learning and social behaviors. Common mental health conditions include depression, PTSD, anxiety, addiction, bipolar disorder (formerly called manic-depressive illness or manic depression), and anorexia nervosa, and expand to include neuro-degenerative diseases such as Parkinson's, Alzheimer's disease, and ALS (amyotrophic lateral sclerosis), among others. Substance use disorders occur when the recurring use of alcohol and/or drugs causes clinically significant impairment, including health problems, disability, and failure to meet major responsibilities at work, home, or school. The Lancet Commission, a group of experts in neuroscience, psychiatry, public health, and related fields, estimates that the cost of mental disorders, currently on the rise in every country, will reach $16 trillion by 2030, including costs associated with lost productivity.
