The global obesity-diabetes drugs market is
projected to be worth around $100
billion by 2034[1] –
largely driven by Glucagon-like peptide-1 (GLP-1) inhibitors like
Novo Nordisk's Ozempic® and Wegovy® and Eli
Lilly's Trulicity® and Mounjaro® and sodium
glucose cotransporter-2 (SGLT2) inhibitors such as Boehringer
Ingelheim's Jardiance®

Positive results from multiple in vivo studies
show the impact of sphingosine kinase-2 (SPHK2) inhibition in
various models of metabolic disease, supporting the potential of
opaganib therapy for diabetes and obesity-related disorders

With multiple U.S. government collaborations
ongoing, opaganib is a novel, host-directed, potentially broad
acting, orally administered small molecule drug with demonstrated
safety & efficacy profiles. It is in development for multiple
oncology, viral, inflammatory and diabetes and obesity-related
indications, including COVID-19, Ebola, acute respiratory distress
syndrome (ARDS) and radio/chemical protection
TEL-AVIV, Israel and RALEIGH, N.C., Aug. 19,
2024 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq:
RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical
company, today announced positive results from multiple in
vivo studies, undertaken by RedHill's partner, Apogee
Biotechnology Corporation, showing the impact of
opaganib[2] on weight gain and glucose tolerance in a
high fat diet (HFD) model, supporting the potential clinical use of
opaganib for the prevention and therapy of Type 2 diabetes and
other obesity-related disorders.

"Sphingolipid metabolism is implicated in insulin resistance,
β-cell disruption, adipocyte function, inflammation and immune
regulation, vascular complications and energy metabolism – all
significant components of obesity, diabetes and their associated
complications," said Charles D.
Smith, Ph.D. Founder and CEO of Apogee Biotechnology
Corporation. "Opaganib's ability to modulate multiple signaling
pathways through simultaneous inhibition of three
sphingolipid-metabolizing enzymes in human cells provides a strong
rationale for evaluation of opaganib in obesity-related
disorders."
The studies were designed to examine some of the most
fundamental aspects of diabetes and obesity-related disease. The
encouraging outcomes showed the benefit of opaganib therapy in
suppression of HFD-induced body weight gain, loss of glucose
tolerance and fat deposition. Additionally, opaganib treatment
reduced weight gain and restored glucose tolerance in an already
obese HFD model, suggesting its potential for treating, not just
preventing, obesity-related disorders.
"Sphingolipid metabolism is a key pathway in many diseases,
including obesity, but has not been adequately examined as a
therapeutic target for human therapy," said Dr. Mark Levitt, Chief Scientific Officer at
RedHill. "Opaganib, which acts as a sphingosine
competitor, is the first clinical drug to target three key enzymes
in this pathway."
The global obesity-diabetes drugs market is projected to be
worth around $100 billion by 2034 –
largely driven by Glucagon-like peptide-1 (GLP-1) inhibitors like
Novo Nordisk's Ozempic and Wegovy (semaglutide) and Eli Lilly's
Trulicity (dulaglutide) and Mounjaro (tirzepatide) and sodium
glucose cotransporter-2 (SGLT2) inhibitors such as Boehringer
Ingelheim's Jardiance (Empagliflozin).
About Opaganib (ABC294640)
Opaganib, a proprietary investigational host-directed and
potentially broad-acting drug, is a first-in-class, orally
administered sphingosine kinase-2 (SPHK2) selective inhibitor with
anticancer, anti-inflammatory and antiviral activity, targeting
multiple potential diseases, including obesity-related syndromes,
prostate cancer and cholangiocarcinoma (bile duct cancer),
gastrointestinal acute radiation syndrome (GI-ARS), Sulfur Mustard
exposure, COVID-19, Ebola and other viruses as part of pandemic
preparedness.
Opaganib's host-directed action is thought to work through the
inhibition of multiple pathways, the induction of autophagy and
apoptosis, and disruption of viral replication, through
simultaneous inhibition of three sphingolipid-metabolizing enzymes
in human cells (SPHK2, DES1 and GCS).
Opaganib has been selected for evaluation by two U.S. government
countermeasures programs for Acute Radiation Syndrome (ARS) and
Sulfur Mustard exposure, both funded by the NIH: The Radiation and
Nuclear Countermeasures Program (RNCP), led by the National
Institute of Allergy and Infectious Diseases (NIAID), part of the
HHS National Institutes of Health, for the nuclear medical
countermeasures (MCM) product development pipeline selected
opaganib for development as a potential treatment for Acute
Radiation Syndrome (ARS); and the Chemical Medical Countermeasures
(Chem MCM) Program and Chemical Countermeasures Research Program
(CCRP), managed respectively by the Administration for Strategic
Preparedness and Response (ASPR) / Biomedical Advanced Research and
Development Authority (BARDA) and NIH/NIAID selected opaganib for
evaluation as a potential medical countermeasure (MCM) against
Sulfur Mustard exposure.
Opaganib has demonstrated antiviral activity against SARS-CoV-2,
multiple variants, and several other viruses, such as Influenza A
and Ebola. Opaganib delivered a statistically significant increase
in survival time when given at 150 mg/kg twice a day (BID) in a
United States Army Medical Research Institute of Infectious
Diseases (USAMRIID) in vivo Ebola virus study, making it the
first host-directed molecule to show activity in Ebola virus
disease. Opaganib also recently demonstrated a distinct synergistic
effect when combined individually with remdesivir (Veklury®, Gilead
Sciences Inc.), significantly improving potency while maintaining
cell viability, in a U.S. Army-funded and conducted in vitro
Ebola virus study.
Being host-targeted, and based on data accumulated to date,
opaganib is expected to maintain effect against emerging viral
variants. In prespecified analyses of Phase 2/3 clinical data in
hospitalized patients with moderate to severe COVID-19, oral
opaganib demonstrated improved viral RNA clearance, faster time to
recovery and significant mortality reduction in key patient
subpopulations versus placebo on top of standard of care. Opaganib
has demonstrated its safety and tolerability profile in more than
470 people in multiple clinical studies and expanded access use.
Data from the opaganib global Phase 2/3 study was published
in medRxiv.
Opaganib has received Orphan Drug designation from the FDA for
the treatment of cholangiocarcinoma and has undergone studies in
advanced cholangiocarcinoma (Phase 2a) and prostate cancer.
Opaganib also has a Phase 1 chemoradiotherapy study protocol ready
for FDA-IND submission.
Opaganib has also shown positive preclinical results in renal
fibrosis, and has the potential to target multiple oncology,
radioprotection, viral, inflammatory, and gastrointestinal
indications.
