Acute Radiation Syndrome

U.S. Patent and Trademark Office (USPTO) issues new patent covering Talicia1 as an all-in-one treatment of Helicobacter pylori (H. pylori), supporting Talicia protection until February 12, 2034 This new patent adds to the existing strong intellectual property portfolio protecting Talicia, including composition of matter and other patents and FDA-granted data exclusivities granted under the GAIN QIDP designation and section 505(b)(2) Talicia is the only FDA-approved rifabutin-containing all-in-one therapy for the eradication of H. pylori, providing an optimized antibiotic resistance profile and the leading branded first-line therapy prescribed by U.S. gastroenterologists2 for H. pylori infection, which affects approximately 35% of the U.S. adult population3 TEL AVIV, Israel and RALEIGH, N.C., March 11, 2024 /PRNewswire/ -- RedHill Biopharma Ltd. (NASDAQ: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced the issue of a new U.S. patent covering Talicia1 as an all-in-one fixed-dose combination of amoxicillin, omeprazole and rifabutin and its use for the treatment of helicobacter pylori (H. pylori) infection (Patent No. 11,931,463 to be issued March 19, 20244). Talicia is the leading branded first-line therapy prescribed by U.S. gastroenterologists for H. pylori infection, which affects approximately 35% of the U.S. adult population and this patent is expected to provide protection for Talicia until February 12, 2034. "Talicia is the only FDA-approved rifabutin-containing all-in-one therapy for the eradication of H. pylori. Its components and formulation are optimized to provide patients with the right medications for successful H. pylori eradication with an optimized resistance profile, which is significant in the face of growing microbial resistance to clarithromycin-based regimens," said Patricia Anderson, RedHill's Senior Vice President of Regulatory Affairs. "The granting of this new U.S. patent further adds to the strong intellectual property protecting Talicia, including the recently announced patent for treatment regardless of patient Body Mass Index (BMI), several other composition of matter and other patents, and additional FDA-granted data exclusivities granted under the Generating Antibiotic Incentives Now (GAIN) Act Qualified Infectious Disease Product (QIDP) designation and the approval of Talicia under section 505(b)(2)." About H. pylori infection H. pylori is a bacterial infection that affects approximately 35% of the U.S. population, with an estimated two million patients treated annually5. Worldwide, more than 50% of the population has H. pylori infection, which is classified by the World Health Organization (WHO) as a Group 1 carcinogen. It remains the strongest known risk factor for gastric cancer6 and a major risk factor for peptic ulcer disease7 and gastric mucosa-associated lymphoid tissue (MALT) lymphoma8. More than 27,000 Americans are diagnosed with gastric cancer annually9. Eradication of H. pylori is becoming increasingly difficult, with current therapies failing in approximately 25-40% of patients who remain H. pylori-positive due to high resistance of H. pylori to antibiotics – especially clarithromycin – which is still commonly used in standard combination therapies. About Talicia Talicia is a novel, fixed-dose, all-in-one oral capsule combination of two antibiotics (amoxicillin and rifabutin) and a proton pump inhibitor (PPI) (omeprazole), approved by the U.S. Food and Drug Administration (FDA) for the treatment of H. pylori infection in adults. Talicia is the only low-dose rifabutin-based therapy approved for the treatment of H. pylori infection and is designed to address H. pylori's high resistance to other antibiotics. The high rates of H. pylori resistance to clarithromycin have led to significant rates of treatment failure with clarithromycin-based therapies and are a strong public health concern, as highlighted American College of Gastroenterology, the FDA and the WHO in recent years. In the pivotal Phase 3 study, Talicia demonstrated 84% eradication of H. pylori infection in the intent-to-treat (ITT) group vs. 58% in the active comparator arm (p<0.0001). Minimal to zero resistance to rifabutin, a key component of Talicia, was detected in RedHill's pivotal Phase 3 study. Further, in an analysis of data from this study, it was observed that subjects who were confirmed adherent10 to their therapy had response rates of 90.3% in the Talicia arm vs. 64.7% in the active comparator arm11. To reduce the development of drug-resistant bacteria and maintain the effectiveness of Talicia and other antibacterial drugs, Talicia should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. Talicia is eligible for a total of eight years of U.S. market exclusivity under its Qualified Infectious Disease Product (QIDP) designation and is also covered by U.S. patents which extend patent protection until 2034 with additional patents and applications pending and granted in various territories worldwide.

The U.S. government's Chemical Medical Countermeasures (Chem MCM) Program and Chemical Countermeasures Research Program (CCRP), managed respectively by ASPR/BARDA and NIH/NIAID, in collaboration with Battelle[1], have selected opaganib for evaluation as a potential medical countermeasure (MCM) against Sulfur Mustard exposure Opaganib, a novel oral small molecule, is the first sphingosine kinase-2 (SPHK2) inhibitor investigational drug targeting sphingolipid metabolism to be evaluated as a chemical countermeasure Selection for the therapeutic testing/screening program, following opaganib's previous acceptance into the Radiation and Nuclear Countermeasures Program (RNCP) for Acute Radiation Syndrome (ARS), provides the potential to see broad activity across both radiation and Sulfur Mustard injuries Opaganib has five-year shelf-life and is easy to administer and distribute for use against potential chemical weapon attack, if approved by the U.S. Food and Drug Administration (FDA) Opaganib is being developed for multiple additional indications, including COVID-19, acute respiratory distress syndrome (ARDS) and oncology TEL AVIV, Israel and RALEIGH, N.C., March 5, 2024 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, together with its partner Apogee Biotechnology Corporation, today announced that opaganib[2] has been selected by the U.S. government's Chemical Medical Countermeasures (Chem MCM) Program and Chemical Countermeasures Research Program (CCRP) for evaluation as a potential medical countermeasure (MCM) against inhalation Sulfur Mustard exposure. The overall evaluation will also include assessment of opaganib's efficacy against sub-chronic fibrosis and acute respiratory distress syndrome (ARDS) resulting from Sulfur Mustard exposure. The Chem MCM Program is administered by the Biomedical Advanced Research and Development Authority (BARDA), a component of the Administration for Strategic Preparedness and Response (ASPR) within the U.S. Department of Health and Human Services (HHS), and the CCRP is managed by the National Institute of Allergy and Infectious Diseases (NIAID), part of the HHS National Institutes of Health (NIH). Sulfur Mustard is a powerful alkylating chemical warfare agent. Exposure to Sulfur Mustard causes extensive skin blistering and severe injury to the eyes, lungs, and multiple organs, causing potentially fatal damage. Primarily affecting the lungs, Sulfur Mustard poisoning can result in symptoms such as acute lung injury, acute respiratory distress syndrome, bronchiolitis obliterans, fibrosis, and subsequent associated infections. "With the alarming increase in global geo-political instability, the opportunity to evaluate opaganib as a potential vital protective agent against chemical attack is inspiring. We, and our development partner, Apogee Biotechnology Corporation, are delighted to partner with the NIH/NIAID, ASPR/BARDA, and Battelle in our efforts to make a significant difference in this area of huge medical and societal need," said Dror Ben-Asher, RedHill's Chief Executive Officer. "Opaganib is the first selective sphingosine kinase-2 (SPHK2) inhibitor investigational drug targeting sphingolipid metabolism to be evaluated as a chemical countermeasure. Its selection for the U.S. government's Chemical Countermeasures Research Program, following opaganib's previous acceptance into the U.S government's Radiation and Nuclear Countermeasures Program for Acute Radiation Syndrome (ARS), provides the potential to see broad activity across both radiation and Sulfur Mustard injuries." Opaganib, a novel oral, small molecule pill with a five-year shelf-life, is easy to administer and distribute for use against potential chemical weapon attack, if approved by the FDA. 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 gastrointestinal acute radiation syndrome (GI-ARS), COVID-19, other viruses as part of pandemic preparedness, and cholangiocarcinoma (bile duct cancer). 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 was selected by the U.S. government's Radiation and Nuclear Countermeasures Program (RNCP), led by the National Institute of Allergy and Infectious Diseases, part of the HHS National Institutes of Health, for the nuclear medical countermeasures product development pipeline as a potential treatment for Acute Radiation Syndrome (ARS). Opaganib has demonstrated antiviral activity against SARS-CoV-2, multiple variants, and several other viruses, such as Influenza A. Opaganib also recently demonstrated a distinct synergistic effect when combined individually with remdesivir (Veklury®, Gilead Sciences Inc., Nasdaq: GILD), 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.

– Innovative design enables five-minute pegfilgrastim-cbqv delivery time – – Unique, automatic, retractable needle mechanism engineered to maximize safety and comfort for cancer patients receiving UDENYCA® – REDWOOD CITY, Calif., Feb. 21, 2024 (GLOBE NEWSWIRE) -- Coherus BioSciences, Inc. (Coherus, NASDAQ: CHRS) today announced the launch of UDENYCA ONBODY™, the company's on-body injector (OBI) presentation of UDENYCA® (pegfilgrastim-cbqv), is successfully underway, with a broad distribution of accounts nationwide ordering this innovative device, and patients now accessing its benefits. UDENYCA is a pegfilgrastim biosimilar administered the day after chemotherapy to decrease the incidence of infection as manifested by febrile neutropenia. “It’s exciting to have a new biosimilar pegfilgrastim on-body option, especially for those who live far away from their care centers,” said Kathleen Clifford, Clinical Oncology Nurse Practitioner at St. Luke's Health System. “The thoughtful design of this device, with its distinct features, has advantages for our patients and gives me confidence that their treatment will be administered even though it’s taking place away from the office.” UDENYCA ONBODY was designed with patients in mind; key features include a five-minute injection time, an indicator, status light and auditory signal that help patients confirm the dose has been administered and a strong and well-tolerated adhesive. After the dose is administered, the needle automatically retracts, which reduces the risk of needlestick injury. “We are excited that UDENYCA ONBODY is now available for cancer patients, and provider response to UDENYCA ONBODY’s unique features, including a five-minute injection time and novel retractable needle mechanism, has been very positive,” said Paul Reider, Coherus’ Chief Commercial Officer. “The ONBODY device is the third presentation in the UDENYCA franchise, which also includes a prefilled syringe and autoinjector. The growing demand for UDENYCA is evidence that innovating cancer care for patients is a winning strategy.” “The UDENYCA portfolio gives patients the opportunity to align their needs with a pegfilgrastim treatment plan,” said Maria Theodoulou, M.D., of New York Oncology Hematology. “Patients can continue to receive immune supportive care in a variety of settings, such as the clinic by a health care provider or at home via preset administration with UDENYCA ONBODY or self-administration with UDENYCA autoinjector. Where a cancer diagnosis takes empowerment away from patients, UDENYCA gives it back.” UDENYCA ONBODY is available through existing full-line and specialty distributors. Billing under the medical benefit for UDENYCA ONBODY is streamlined because it has the same permanent, product-specific Q-Code as the prefilled syringe, Q5111, and a unique NDC number of 70114-0130-01. UDENYCA Solutions™ offers healthcare professionals comprehensive practice and patient support that includes extensive patient assistance and office support to ensure successful access, billing, and reimbursement. More details regarding UDENYCA ONBODY, including video instructions for ONBODY preparation and application, can be found at . About UDENYCA UDENYCA® is the only pegfilgrastim brand approved in the United States available in three administration options—prefilled syringe (PFS), autoinjector (AI) and on-body injector—providing patients and healthcare providers with choice, control, and convenience. Since its launch in 2019, over 300,000 patients have been treated with UDENYCA. INDICATION UDENYCA® is a leukocyte growth factor indicated to: Decrease the incidence of infection, as manifested by febrile neutropenia, in patients with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a clinically significant incidence of febrile neutropenia.

Acute respiratory distress syndrome (ARDS): Evaluate patients who develop fever, lung infiltrates, or respiratory distress. Discontinue UDENYCA® in patients with ARDS. Serious allergic reactions, including anaphylaxis: The majority of reported events occurred upon initial exposure. Allergic reactions, including anaphylaxis, can recur within days after the discontinuation of initial anti-allergic treatment. Permanently discontinue UDENYCA® in patients with serious allergic reactions. Allergies to Acrylics: The on-body injector (OBI) for UDENYCA uses acrylic adhesive. For patients who have reactions to acrylic adhesives, use of this product may result in a significant reaction. Sickle cell crises: Severe and sometimes fatal crises have occurred. Discontinue UDENYCA® if sickle cell crisis occurs. Glomerulonephritis: The diagnoses were based upon azotemia, hematuria (microscopic and macroscopic), proteinuria, and renal biopsy. Generally, events resolved after dose reduction or discontinuation. Evaluate and consider dose-reduction or interruption of UDENYCA® if causality is likely. Leukocytosis: White blood cell (WBC) counts of 100 x 109/L or greater have been observed in patients receiving pegfilgrastim products. Monitoring of complete blood count (CBC) during UDENYCA® therapy is recommended. Thrombocytopenia: Thrombocytopenia has been reported in patients receiving pegfilgrastim. Monitor platelet counts. Capillary Leak Syndrome: Has been reported after G-CSF administration, including pegfilgrastim products, and is characterized by hypotension, hypoalbuminemia, edema, and hemoconcentration. Episodes vary in frequency, severity and may be life-threatening if treatment is delayed. If symptoms develop, closely monitor and give standard symptomatic treatment, which may include a need for intensive care. Potential for Tumor Growth Stimulatory Effects on Malignant Cells: The possibility that pegfilgrastim products act as a growth factor for any tumor type, including myeloid malignancies and myelodysplasia, diseases for which pegfilgrastim products are not approved, cannot be excluded. Myelodysplastic Syndrome (MDS) and Acute Myeloid Leukemia (AML) in Patients with Breast and Lung Cancer: MDS and AML have been associated with the use of pegfilgrastim in conjunction with chemotherapy and/or radiotherapy in patients with breast and lung cancer. Monitor patients for sign and symptoms of MDS/AML in these settings. Potential Device failures: Missed or partial doses have been reported for products administered via on-body injectors due to the device not performing as intended. In the event of a missed or partial dose, patients may be at increased risk of events such as neutropenia, febrile neutropenia and/or infection than if the dose had been correctly delivered. Instruct patients using the OBI to notify their healthcare professional immediately to determine the need for a replacement dose of UDENYCA if they suspect that the device may not have performed as intended. Aortitis: Has been reported in patients receiving pegfilgrastim products, occurring as early as the first week after start of therapy. Manifestations may include generalized signs and symptoms such as fever, abdominal pain, malaise, back pain, and increased inflammatory markers (e.g., c-reactive protein and white blood cell count). Consider aortitis when signs and symptoms develop without known etiology. Discontinue UDENYCA® if aortitis is suspected. Nuclear Imaging: Increased hematopoietic activity of the bone marrow in response to growth factor therapy has been associated with transient positive bone imaging changes. Consider when interpreting bone imaging results. ADVERSE REACTIONS: Most common adverse reactions (≥ 5% difference in incidence compared to placebo) are bone pain and pain in extremity.
