Dror Ben-Asher, RedHill’s Chief Executive Officer, said: "We have undergone an extensive overhaul reshaping ourselves financially, operationally and strategically. Major corporate and R&D moves, undertaken over the last 12 months, have resulted in new and clearer opportunities to deliver maximum value from both our commercial and R&D assets. The potential $60 million ex-North America global license of RHB-102 to Hyloris lays the groundwork for the ongoing development and commercialization in the large gastroenteritis, oncology support and IBS-D markets while enabling RedHill to maintain control of the key North American markets. The approximately $8 million plus legal costs New York Supreme Court summary judgment was a resounding win for RedHill and we are fully committed to pursuing the collection of this award. Last year’s recommendation by the latest ACG Clinical Guideline for Talicia as a first-line therapeutic option for H. pylori eradication, has, we expect further enhanced Talicia’s product profile as the leading branded U.S. gastroenterologist prescribed H. pylori therapy, winning additional formulary successes securing 25 million covered lives. After its successful launch in UAE, Talicia is also poised for a potential UK Marketing Authorisation Application (MAA) mid-year, presenting a promising pathway for Talicia’s entry into additional markets globally."

Mr. Ben-Asher continued: "Having successfully completed the Hyloris RHB-102 out-license deal, we are now advancing our next-generation candidate, RHB-204, in the $12 billion Crohn’s disease space, employing a novel, groundbreaking approach, supported by RHB-104’s positive Phase 3 clinical data. In parallel, opaganib continues to show its broad-acting potential and we are very excited to have initiated the innovative Bayer-supported Phase 2 study in combination with darolutamide, which may bring vital new hope to men with metastatic castrate resistant prostate cancer. Progress was also made with opaganib as a treatment for GI-ARS following positive results from new in vivo studies, undertaken as part of the U.S. government’s Radiation and Nuclear Countermeasures Program (RNCP) product pipeline development contract, further confirming opaganib’s radioprotective activity in models of GI-ARS. Discussions are ongoing regarding advanced development. Additionally, the ongoing U.S. Government-supported work in Ebola continues following our previously announced BARDA grant. We have started 2025 as we mean to go on – aggressively pursuing our business goals and aiming to deliver on our catalysts in a meaningful way."

Financial results for the 12 months ended December 31, 20242

Net Revenues for the year ended December 31, 2024 were $8.0 million, compared to $6.5 million for the year ended December 31, 2023. Talicia net revenues for the year ended December 31, 2024, increased to $9.0 million from $8.8 million for the year ended December 31, 2023, driven by approximately $1.0 million of revenues generated from the UAE partnership with Gaelan Medical. Net revenues for the years ended December 31, 2024 and December 31, 2023 included Movantik contra-revenues of $0.9 million and $2.6 million for Movantik, respectively, mainly due to product returns.

Cost of Revenues for the year ended December 31, 2024 was $3.2 million, compared to $3.5 million for the year ended December 31, 2023. The decrease was primarily due to lower inventory write-downs, which totaled $0.2 million in 2024 compared to $1.3 million in 2023.

Gross Profit for the year ended December 31, 2024 was $4.9 million, compared to $3.1 million for the year ended December 31, 2023, reflecting the increase in net revenues and the lower level of inventory write-downs in 2024.

Research and Development Expenses for the year ended December 31, 2024 were $1.6 million, as compared to $3.5 million for the year ended December 31, 2023. The decrease was attributable to the costs from closing the RHB-204 clinical trial, which were recognized in 2023, as well as ongoing cost-reduction measures.

Selling, Marketing, and General and Administrative Expenses for the year ended December 31, 2024 were $15.5 million, as compared to $31.0 million for the year ended December 31, 2023. The reduction was primarily attributable to ongoing cost-reduction measures and the divestment of Movantik in 2023, which led to workforce downsizing and other related expense reductions.

Other Expenses for the year ended December 31, 2024 were $2.3 million, recognized as part of the Global Termination Agreement3, as compared to Other Income of $44.1 million for the year ended December 31, 2023. The Other Income in 2023 was comprised of (i) $35.5 million from the divestiture of Movantik, calculated as the difference between the fair value of the rights and the carrying amount of this asset and (ii) $8.6 million from transitional services provided to the buyer of Movantik.

Operating Loss for the year ended December 31, 2024 was $14.6 million, compared to Operating Income of $12.6 million for the year ended December 31, 2023. Both periods include items related to the Movantik divestiture, as described under Other Expenses – a $2.3 million loss in 2024 and $44.1 million income in 2023. Excluding these, the year-over-year change reflects improved operating performance driven by cost-cutting measures.

Financial Income, net for the year ended December 31, 2024 was $6.3 million, compared to Financial Income, net of $11.3 million for the year ended December 31, 2023. The income recognized for the year ended December 31, 2024, was primarily driven by the revaluation of financial instruments, partially offset by other financing expenses. The income recognized in the year ended December 31, 2023, was primarily attributable to a $20.6 million gain resulting from the extinguishment of the HCRM debt in exchange for the transfer of rights to Movantik, calculated as the difference between the carrying amount of the financial liability and the fair value of the rights transferred, partially offset by financial expenses related to the financial instruments and other financial expenses.

Net Loss for the year ended December 31, 2024 was $8.3 million, as compared to Net Income of $23.9 million for the year ended December 31, 2023. Both periods include impacts from the Movantik divestiture, as detailed under Other Expenses and Financial Income – a $2.3 million loss in 2024 and $64.7 million in income in 2023. Excluding these, the year-over-year change reflects improved performance driven by cost cutting measures.

Total Assets as of December 31, 2024 were $18.0 million, as compared to $23.0 million as of December 31, 2023. The decrease was primarily attributable to the decrease in cash balance, reduced inventory and a decline in prepaid expenses and other receivables, consistent with the Company’s scaled-down operations, as well as impact of balances settled as part of the Global Terminations Agreement, and a reduction in right-of-use assets following the termination of vehicle leases during 2024.

Total Liabilities as of December 31, 2024 were $22.7 million, as compared to $21.0 million as of December 31, 2023. The increase primarily reflects the impact of the Global Termination Agreement, under which the Company incurred liabilities related to Movantik that were allocatable to HCRM and its affiliates under their agreements with the Company, offset by payments made toward these liabilities during the period. Additionally, there was an increase in derivative financial instruments associated with warrant liabilities from offerings made during 2024. This was partially offset by a decrease in accounts payable and allowance from deductions from revenues, consistent with the Company’s scaled-down operations, as well as a reduction in lease liabilities due to the termination of car leases.

Net Cash Used in Operating Activities for the year ended December 31, 2024 was $9.4 million, compared to $35.8 million for the year ended December 31, 2023. The cash used in operating activities was primarily directed towards settling pre-closing liabilities related to Movantik and other operational activities. This was partially offset by proceeds received from the Global Termination Agreement, net of payments made to settle obligations arising from this agreement.

Net Cash Provided by Financing Activities for the year ended December 31, 2024 was $8.4 million, primarily generated through equity offerings. Net Cash Provided by Financing Activities for the year ended December 31, 2023, was $21.4 million, comprised primarily of proceeds from equity offerings and exercise of certain warrants in transactions consummated in each of April 2023, July 2023, September 2023 and November 2023, and from decrease in restricted cash, partially offset by repayment of payables in respect of intangible asset purchases.

Cash Balance as of December 31, 2024, was $4.8 million1.

Commercial and R&D Highlights:

Commercial – streamlined and revenue-generating:

With a significantly streamlined commercial operation, Talicia has generated net revenues of $9.0 million, supported by approximately $1.0 million of new revenues from the UAE partnership with Gaelan Medical, and remains the leading U.S. gastroenterologist-prescribed branded H. pylori therapy.

Significant effort has resulted in important accomplishments with Talicia, such as the inclusion as first-line option for treatment of H. pylori infection in the recently updated 2024 American College of Gastroenterology (ACG) Clinical Guideline, the securing of 25 million covered lives following the Medi-Cal renewal and Humana formulary win, a successful launch in the UAE and the potential for opening up new markets with the recently announced plan for a Talicia UK MAA. Talicia has now surpassed the 100,000 prescriptions milestone and our innovative warranty program, with minimal refunds claimed, reflects a positive patient experience.

R&D – focused on new opportunities:

Largely externally funded, with multiple U.S. Government and non-governmental collaborations, RedHill’s pipeline provides new and exciting opportunities in major indications: Crohn’s disease, prostate cancer, diabetes and obesity-related disorders, Ebola and other viral and pandemic preparedness indications as well as for gastrointestinal-acute radiation syndrome (GI-ARS) and other medical/chemical countermeasure uses:

Opaganib4:

A potentially broad acting, novel, oral, host-directed small molecule drug, with a demonstrated safety and efficacy profile, advancing in predominantly U.S. Government-supported, externally funded programs, directed at multiple underserved indications with sizeable multi-billion-dollar market opportunities and potentially advantageous pathways to approval.

Opaganib is in development for multiple oncology, viral, inflammatory and diabetes and obesity-related indications, including prostate cancer, COVID-19, Ebola, acute respiratory distress syndrome (ARDS) and radio/chemical protection, including GI-ARS:

A new approach in the $12 billion prostate cancer market:

Prostate cancer (PC) is the second most diagnosed cancer in the world, with around 1.5 million new cases per year, causing almost 400,000 deaths5. People with metastatic castrate-resistant prostate cancer (mCRPC) have few treatment options available to them.

In February 2025, the Company announced the initiation of a Bayer-supported Phase 2 study of opaganib in combination with Bayer’s darolutamide in mCRPC, evaluating the potentially enhancing effect of opaganib in patients with poor prognosis.

The study will utilize a companion lipid biomarker test (PCPro) to select mCRPC patients who have a poor prognosis due to standard of care (SoC) treatment and who may benefit from an opaganib + darolutamide combination treatment approach. The primary endpoint will be improved 12-month radiographic progression-free survival (rPFS).

Other opaganib programs/updates include:

U.S. Army and BARDA-grant funded program for Ebola. Opaganib is believed to be the first host-directed molecule to show activity in vivo in Ebola virus disease, delivering a statistically significant increase in survival and, separately, demonstrating a robust synergistic effect in vitro when combined with remdesivir (Veklury; Gilead Sciences, Inc.), improving viral inhibition while maintaining cell viability
U.S. Government- and non-government funded programs ongoing with the NIH / BARDA-funded nuclear and chemical medical countermeasure programs for GI-ARS and Phosgene inhalation injury. On December 10, 2024, the Company announced positive results from new in vivo studies of opaganib as a treatment for GI-ARS, undertaken as part of the U.S. Government’s Radiation and Nuclear Countermeasures Program (RNCP) product pipeline development contract. These results further confirm opaganib’s protective activity in models of GI-ARS and discussions are ongoing regarding advanced development.
Positive in vivo study results support potential of opaganib therapy in diabetes / obesity-related disorders – a market projected to be worth approximately $100 billion within the next decade. ‘Opaganib Promotes Weight Loss and Suppresses High-Fat Diet-Induced Obesity and Glucose Intolerance’ was recently published6 in the journal Diabetes, Metabolic Syndrome and Obesity
Orphan drug designation granted by FDA for neuroblastoma (opaganib has several such designations in multiple indications, with three in oncology)
ARDS, COVID-19 and Influenza programs continue to seek to address multi-hundreds of millions of dollars markets
RHB-204:

RHB-204 is a proprietary, fixed-dose oral capsule containing a combination of clarithromycin, rifabutin and clofazimine, at specific doses designed to safely and effectively treat Mycobacterium avium subspecies paratuberculosis-positive (MAP-positive)-related Crohn’s disease (CD). Unlike existing therapies that focus on symptom relief, RHB-204 is intended to target the possible root cause of Crohn’s disease, which is hypothesized to be caused by Mycobacterium avium subspecies paratuberculosis (MAP).

Patent protected until at least 2041, RHB-204 is a next-generation formulation of RHB-104, which successfully completed a Phase 3 study in Crohn’s disease, with an optimized formulation for the treatment of CD. It contains the same three antimicrobial agents with potent intracellular, anti-mycobacterial and anti-inflammatory properties, and with an optimized dosing profile, RHB-204 provides the potential for enhanced tolerability, safety and compliance with a 40% pill burden reduction. RHB-204 is supported by a strong foundation of clinical data from the positive safety and efficacy results achieved in the Phase 3 study of RHB-104 in CD, with its potential further demonstrated using mucosal healing imaging, considered to be the gold standard for efficacy evaluation in CD.

Paradigm shift in MAP-positive CD treatment approach

In March 2025, the Company announced its plans to advance its potentially groundbreaking late-stage RHB-204 Crohn’s disease program, building on statistically significant positive RHB-104 Phase 3 results. FDA guidance on pathway to approval is anticipated in the coming weeks. RedHill is actively pursuing funding opportunities and partnerships to advance this potential paradigm-shifting treatment.

The planned innovative Phase 2 study of RHB-204 is planned to be the first ever clinical study in CD patients who are all MAP-positive and will evaluate mucosal healing, a new gold standard in assessing efficacy in Crohn’s disease, and MAP eradication utilizing novel and decisive endpoints and imaging, allowing for a study design with a relatively small sample size.

RHB-204 builds upon RHB-104’s successful Phase 3 study, which successfully met its Phase 3 study primary and secondary endpoints demonstrating a statistically significant 64% improvement in efficacy versus standard of care. It also showed compelling mucosal healing data in CD patients who underwent colonoscopy. The inclusion of MAP-positive only patients in the planned study with RHB-204 is anticipated to demonstrate a more consistent benefit in the study population across all efficacy outcomes.

RHB-107 (upamostat) update:

On January 30, 2025, we were notified that funding from the U.S. Government Department of Defense’s Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense (JPEO-CBRND) for the ongoing 300-patient Phase 2 RHB-107 arm of the ACESO PROTECT platform trial for early COVID-19 outpatient treatment was subject to termination, requiring the study to cease enrollment on Feb 28, 2025. 93 patients have been enrolled out of a fully enrolled target patient population of 300. Due to the reduced number of patients enrolled in this study, the study result may not lead to conclusions regarding the efficacy of RHB-107 in this trial.

The U.S. Army-funded Ebola development program remains ongoing, with RHB-107 having demonstrated a robust synergistic effect in vitro when combined with remdesivir. Management of potential Ebola virus pandemic outbreaks represents a significant opportunity and is a key concern for global health agencies.

No adverse events greater than Grade 2 attributable to the investigational regimen and no dose-limiting toxicities (DLTs) were observed.
CD4+ (13/13) and CD8+ (11/13) central memory T-cell compartments expanded post-vaccination (p<0.002 and p<0.05, respectively), indicating robust immune activation.
CD8+CD127+ memory precursor effector cells (MPECs) expanded in 12/13 patients (p<0.001), suggesting enhanced immune memory potential.
Spatial transcriptomics analysis of three patients showed intense CD25+ foci overlapping effector memory T-cell and migratory microglial markers post-vaccination.
One-year overall survival (OS) rate in the 15/16 unmethylated cohort was 88%, compared to 53% in an age-matched control cohort (p<0.002), highlighting a potential survival benefit.
"In the Phase I trial, the dendritic vaccine injections at the lymph nodes were well tolerated, with no significant side effects observed in any participants," said Dr. Jay-Jiguang Zhu, Principal Investigator of the study and Professor and Director of Neuro-oncology at UTHealth Houston. "We are looking forward to assessing this dendritic cell-based vaccine therapy in the upcoming Phase II trial."

About DOC1021

DOC1021 is an autologous dendritic cell vaccine (DCV) that initiates a complete cytotoxic TH1 immune response against a patient’s cancer through the company’s proprietary double loading technology. The vaccines are made with a patient’s dendritic cells combined with mRNA and proteins prepared from freshly obtained patients’ tumor specimens.

This unique approach unlocks a synergistic tumor killing TH1 response driven by dual protein and RNA antigen sourcing, and it allows targeting of the complete cancer antigen pool. Moreover, the approach does not require any molecular modification of the patient’s immune cells for manufacturing, and does not require preconditioning of bone marrow or high dose IL-2 for administration.

In addition to the lead GBM study, a clinical trial of another Diakonos dendritic cell vaccine is ongoing for the treatment of pancreatic cancer. Diakonos has received Fast Track designations from the FDA for both the GBM and pancreatic cancer programs. The company has also received Orphan Drug Designation for the GBM program.

The vaccine is designed to stimulate a robust immune response, including activation of CD8+ cytotoxic T cells, to eliminate residual cancer cells expressing the target antigens, reducing the risk of disease recurrence. Tumour antigen targets for ITOP1, Infinitopes’ lead asset from its Precision Immunomics platform, are derived using the company’s bespoke AI/ML-driven immunopeptidomics approach and demonstrate high tumour-specificity and inter-patient conservation with potential clinical applicability across multiple cancer types.

The VISTA* study is a phase I/IIa double-blind, randomised, placebo-controlled trial to assess the safety, tolerability and anti-tumour activity of ITOP1 in reducing OAC recurrence rates. 60 patients will receive ITOP1 in a prime/boost regimen, in combination with the best standard of care, i.e., a priming dose following neoadjuvant and a boost dose before adjuvant FLOT (fluorouracil, leucovorin, oxaliplatin, and docetaxel) chemotherapy. Infinitopes’ VISTA trial will be one of the first in the world to administer a cancer vaccine in the neoadjuvant setting while the primary tumour remains in situ, unlocking the potential for enhanced protection from epitope spreading.

The multicentre VISTA study will be conducted at specialist cancer centres in the UK under the leadership of Prof Mark Middleton, a world-renowned Chief Investigator. The VISTA* study is set to commence in Q2 2025. For further details, visit the UK Clinical Trials Registry for Integrated Research Application System (IRAS) project 1008088.

Prof Mark Middleton, Chief Investigator, Head of Oncology & Co-director, CRUK Oxford Centre, University of Oxford, and Scientific Advisory Board Member for Infinitopes, said: "Half of us will suffer cancer in our lifetimes, so we need better, affordable treatments for the disease. ITOP1 is an exciting new immunotherapy with the potential to make a difference across a wide range of cancers, bringing hope to many patients. This first trial in oesophageal cancer will evaluate ITOP1’s precision targeting, which enables anti-tumour immunity through epitope spreading to tackle residual cancer cells and prevent recurrence. We are particularly excited that, by working with the MHRA, we can test ITOP1 where we believe it will achieve the best protection, in potentially curable disease."

Dr Jonathan Kwok, Chief Executive Officer & Co-Founder at Infinitopes, commented: "We are delighted that we have advanced our lead vaccine candidate, ITOP1, from university research to a groundbreaking clinical programme in just over three years. This marks a major performance milestone for the company, bringing Infinitopes an important step closer to offering lifesaving solutions for patients with oesophageal and other aggressive cancers. This achievement is a testament to the power of our team, across immunopeptidomics, computational biology/AI/ML, immunology, oncology, advanced trial design, and our collaborations with Cancer Research UK and leading centres around the world."

Infinitopes recently strengthened its scientific and clinical team with the appointments of exceptional industry leaders, Dan Menichella and Jo Brewer, PhD, supporting the company’s ambition to advance ITOP1 through clinical development to prolong survival and improve the quality of life for patients.

Dan Menichella, Non-Executive Director at Infinitopes, noted: "Infinitopes’ Precision Immunomics approach has the potential to revolutionise cancer treatment as we know it today. I am very excited for the start of our VISTA study, to validate our ITOP1 vaccine and the fundamental enabling technologies."

"In the short period since our initial seed funding, Solu Therapeutics has rapidly advanced to a clinical-stage company targeting areas of high unmet medical need for patients," said Philip J. Vickers, President and CEO at Solu Therapeutics. "With this Series A round we are grateful for the continued support from our existing investors and are excited to welcome several new investors who recognize the potential of our novel CyTAC (Cytotoxicity Targeting Chimera) and TicTAC (Therapeutic Index Control Targeting Chimera) platforms. These technologies have demonstrated an unprecedented ability to unlock high-value cell surface targets that are beyond the reach of traditional antibodies, making it possible to eliminate disease-driving cells with greater precision and efficacy."

Proceeds from the Series A financing will be used to complete dose escalation and expansion of the company’s lead CCR2-CyTAC program, STX-0712, for the treatment of CMML. Additionally, the funding will support the generation of new development candidates, including a novel, first-in-class mast cell depletor for immunological diseases, initiation of new discovery programs targeting pathogenic cells, further pipeline expansion, and exploration of new applications for the CyTAC and TicTAC platforms.

STX-0712 is designed to selectively eliminate CCR2-positive malignant monocytes in patients with advanced hematologic malignancies, with an initial focus on CMML. The Phase 1 trial of STX-0712 is an open-label, multicenter study designed in two parts. Part A will focus on dose escalation to determine the maximum tolerated dose and/or minimum effective dose, enrolling participants with resistant/refractory CMML. Part B will further evaluate safety, tolerability, recommended Phase 2 dose and preliminary antitumor activity of STX-0712.

"Our team is thrilled to initiate this first-in-human clinical trial of STX-0712, marking a significant step forward in our mission to develop innovative therapies for patients with high unmet medical needs," said Sergio Santillana MD, Chief Medical Officer. "By directly depleting the CCR2-positive malignant monocytes driving CMML, STX-0712 has the potential to offer a highly specific and targeted therapy for patients who currently have limited treatment options available. This trial represents an important milestone for Solu Therapeutics as we work to bring novel and potentially more effective targeted therapies to patients with CMML and other hematologic malignancies."

In December 2024, Solu Therapeutics presented preclinical data at the 2024 American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting showing robust ex-vivo activity of STX-0712 against CCR2-positive monocytes in CMML patient samples. CMML is characterized by elevated monocyte counts and dysplastic bone marrow features with limited treatment options.

About STX-0712
STX-0712 is a CyTAC designed to target the G-Protein Coupled Receptor CCR2, a selective marker expressed at high levels on malignant monocytes that are key drivers of disease in CMML and other hematologic malignancies. By eliminating CCR2-positive cells, STX-0712 has the potential to offer a more targeted and effective treatment option with minimal effects on non-malignant cells.

8 un-named OST-HOT Listeria constructs designed for off-the shelf treatment of common cancers with shared hotspot mutations and cancer-testes antigen targets.

"The listeria cancer immunotherapy platform holds tremendous potential to improve the outcomes for cancer patients worldwide" said Dr. Robert Petit, Chief Medical & Scientific Officer of OS Therapies. "Immune-checkpoint inhibitors have revolutionized cancer treatment in settings where tumor antigens have generated a sufficient T cell response. However, in many cancers these treatments don’t help because T cell responses against key tumor antigens have not developed. The OST Listeria platform specifically delivers relevant cancer targets directly to the immune system and generates new T cell responses that can be used to fight these cancers and help eliminate metastases. With OST-HER2 and the rest of the listeria platform, we have the potential to generate novel, more potent immune and targeted immune responses against solid tumors, metastatic disease and micro metastases from early-stage to late-stage cancers. I am thrilled to be able to guide the OST-HER2 asset through approval in osteosarcoma, and then fully explore that listeria platform’s potential to improve treatment outcomes for cancer patients."

The global cancer immunotherapy market size was valued at $126 billion in 2023 and is projected to surpass around $296 billion by 2033, according to Nova One Advisor.
