FDA Approves Ekterly (sebetralstat) the First and Only Oral On-demand Treatment for Hereditary Angioedema (HAE)
KalVista Pharmaceuticals, Inc. announced the U.S. Food and Drug Administration (FDA) approval of Ekterly (sebetralstat), a novel plasma kallikrein inhibitor, for the treatment of acute attacks of hereditary angioedema (HAE) in adult and pediatric patients aged 12 years and older. Ekterly is the first and only oral on-demand treatment for HAE.
“The FDA approval of Ekterly is a defining moment for people living with HAE,” said Ben Palleiko, CEO of KalVista. “Ekterly enables people to treat attacks the moment symptoms begin, wherever they are. This approval affirms the strength of our science and deep commitment to the HAE community. I am profoundly grateful to the KalVista team for their dedication and perseverance, and to the patients and healthcare providers, as well as the HAEA and HAEi, for making this possible. Ekterly has the potential to become the foundational treatment for HAE, and our focus now is on delivering it to the people who need it.”
“As the first orally administered on-demand therapy for HAE attacks, Ekterly provides patients and physicians with an important and welcome advance in HAE treatment options,” said Anthony J. Castaldo, chief executive officer of the U.S. Hereditary Angioedema Association.
Prior to Ekterly’s approval, all on-demand HAE treatment options approved in the U.S. required intravenous or subcutaneous administration, which carries a significant treatment burden.1 Even with the use of long-term prophylaxis as a preventative therapy, most people living with HAE continue to have unpredictable attacks and require ready access to on-demand medication.1
“This is an important moment for patients, giving people living with HAE a treatment option that could provide greater independence and control over managing their condition,” said Marc A. Riedl, MD, Professor of Medicine and Clinical Director, U.S. Hereditary Angioedema Association Center at the University of California, San Diego, and an investigator for the KONFIDENT phase 3 trial. "Until now, on-demand treatment relied on injectable subcutaneous or intravenous administration, often resulting in delayed intervention. Having an oral option empowers patients to treat attacks early, which aligns with treatment guidelines and advances our goal as physicians to reduce the overall burden of disease.”
The efficacy and safety of Ekterly was established by the results from KalVista’s phase 3 KONFIDENT clinical trial, which was the largest clinical trial program ever conducted in HAE. Data from KONFIDENT was published in the New England Journal of Medicine in May 2024, showing that Ekterly achieved significantly faster symptom relief, reduction in attack severity, and attack resolution than placebo, and was well-tolerated with a safety profile similar to placebo.2 The trial randomized 136 HAE patients from 66 clinical sites across 20 countries. These results were further supported by the more real-world KONFIDENT-S open-label extension trial, which as of September 2024, showed that EKTERLY enabled patients to treat attacks in a median of 10 minutes following onset. The most recent data from KONFIDENT-S shows that beginning of symptom relief occurred in a median of 1.3 hours among attacks involving the larynx, the abdomen, and for breakthrough attacks among patients receiving long-term prophylaxis. The safety profile of EKTERLY 600 mg in KONFIDENT-S, in a much larger number of attacks (>1700), was consistent with that observed in KONFIDENT.
KalVista will launch Ekterly in the U.S. immediately, and physicians can begin writing prescriptions today. As part of the Company’s commitment to supporting patients, KalVista has established KalVista Cares™, a comprehensive patient support program that offers personalized services and resources for eligible individuals. This includes assistance with navigating insurance coverage, access support, and ongoing help throughout the treatment journey.

FDA Approves Anzupgo (delgocitinib) Cream for the Treatment of Chronic Hand Eczema
LEO Pharma, a global leader in medical dermatology, announced the U.S. Food and Drug Administration (FDA) approval of Anzupgo® (delgocitinib) cream (20 mg/g) for the topical treatment of moderate-to-severe chronic hand eczema (CHE) in adults who have had an inadequate response to, or for whom topical corticosteroids are not advisable.1
Anzupgo is an innovative steroid-free, topical pan-Janus kinase (JAK) inhibitor for adults with CHE.1 Anzupgo inhibits the JAK-STAT pathway, specifically blocking the activity of JAK1, JAK2, JAK3, and tyrosine kinase 2 (TYK2), and suppresses the various inflammatory responses that play a key role in the onset and subsequent flares of CHE.1,2,4
The FDA approval of Anzupgo marks a significant milestone in LEO Pharma’s strategy to expand its presence in the U.S. market and deliver purposeful innovation in skin health. In preparation for bringing Anzupgo to the U.S. patients, LEO Pharma has significantly upscaled its operations across key functions – including a 50% increase in the sales force.
“Anzupgo is a good example of how we transform a real need in the market into medicines that can help make a difference for people living with serious skin diseases such as CHE,” said Christophe Bourdon, CEO, LEO Pharma. “After successfully launching Anzupgo in several countries, we’re proud to now bring this innovation to adult patients with moderate-to-severe CHE in the United States. The approval of Anzupgo reinforces our commitment to investing in difficult-to-treat skin conditions to deliver new treatments to patients where the need is greatest. We’re truly grateful to the patients and physicians who participated in our studies and helped make this approval possible.”
CHE is a highly debilitating inflammatory skin disease that affects approximately one in ten adults worldwide, causing itchy, painful, blistered, or swollen skin that can interfere with daily activities.2,3,5,6 The FDA approval of Anzupgo provides adults in the U.S. living with moderate-to-severe CHE with the first and only treatment option specifically approved for this skin disease, just as it will be the first and only topical pan-JAK-inhibitor on the U.S. market.
“Chronic hand eczema can be a very difficult disease for adults to manage, especially given the lack of treatment options in the U.S. until now,” said Robert Spurr, EVP and President, North America, LEO Pharma. “As the first and only FDA-approved treatment specifically for CHE in the U.S., Anzupgo further establishes our company's real commitment to bringing treatments to market that address unmet needs in medical dermatology.”
The FDA approval is the latest regulatory milestone for Anzupgo, following the European Commission (EC) approval in 2024 and several launches internationally, including Germany, Switzerland, the United Kingdom and the United Arab Emirates.
About Anzupgo (delgocitinib) Cream
Anzupgo® (delgocitinib) cream is currently FDA approved in the U.S. as the first and only treatment for chronic hand eczema (CHE). Anzupgo is also approved in the European Union, United Kingdom, Switzerland and the United Arab Emirates for the treatment of moderate-to-severe chronic hand eczema (CHE) in adults for whom topical corticosteroids are inadequate or not advisable. Anzupgo cream is also under investigation in other markets. Use of Anzupgo in combination with other JAK inhibitors or potent immunosuppressants is not recommended by the U.S. FDA.1
Anzupgo cream is a topical pan-Janus kinase (JAK) inhibitor for the treatment of moderate-to-severe CHE in adults. It inhibits the activation of JAK-STAT signaling, which plays a key role in the pathogenesis of CHE.7
In 2014, LEO Pharma A/S and Japan Tobacco Inc. (JT) entered into a license agreement in which LEO Pharma gained exclusive rights to develop and commercialize delgocitinib for topical use in dermatological indications worldwide, excluding Japan, where JT retains rights.
About Chronic Hand Eczema
Chronic hand eczema (CHE) is defined as hand eczema (HE) that lasts for three or more months or relapses twice or more within a year.5,8 HE is one of the most common skin disorders of the hands and in a substantial number of patients, it can develop into a chronic condition.9 CHE affects approximately one in ten adults worldwide.2,3 It is a fluctuating disorder characterized by itch and pain, and patients may experience signs such as erythema, scaling, lichenification, hyperkeratosis, vesicles, edema, and fissures on hands and wrists.6 The pathophysiology is characterized by skin barrier dysfunction, inflammation of the skin, and alterations of the skin microbiome.2
CHE has been shown to cause psychological and functional burdens that impact patient quality of life,10,11 with approximately 70% of individuals who live with severe CHE admitting to problems in performing everyday activities.12 Furthermore, careers and earning potential have also been shown to be impacted by the burden of living with CHE

GLP-1 diabetes drugs likely trump metformin for curbing dementia risk in type 2 diabetes, study finds
In continuation of my update "Metformin"
GLP-1 receptor agonists, a class of drug used to treat type 2 diabetes, likely trump the widely prescribed metformin for curbing dementia risk in people with the condition, finds the largest study of its kind, published in the open access journal BMJ Open Diabetes Research & Care.
The findings suggest that future clinical guidelines for the treatment of type 2 diabetes would do well to consider prioritizing drugs with both blood glucose and neuroprotective effects, say the researchers.
Published research suggests that both GLP-1 receptor agonists and metformin, which are widely used to treat type 2 diabetes, protect the brains of people with the disease. But as yet there have been no direct real-world comparisons of the potential impact of these drugs on dementia risk—a risk that is around 70% higher in people with type 2 diabetes.
To explore this further, the researchers drew on anonymized electronic health records from a global health research network (Trinetx) spanning the period 2004 to 2024 to track the development of dementia in patients with type 2 diabetes, treated with either GLP-1 receptor agonists or metformin (87,229 patients in each group; average age 58) for at least six consecutive months.
There was no significant difference in vascular dementia risk between the two types of drug when used as first line therapy.
But GLP-1 receptor agonist use was associated with a significantly lower cumulative (10%) risk of developing dementia, overall, with an incidence of almost 2.5% (2,130 people) compared with an incidence of nearly 5% (4,215 people) for metformin.
And specifically, taking this type of drug was associated with a 12% lower risk of developing Alzheimer's disease, and a 25% lower risk of developing non-vascular dementias than metformin use.
Further in-depth analyses showed that these positive effects were evident across all age groups, but with the strongest effect among the over 60s, women, and those of white ethnicity.
Risk of death from any cause was also lower: nearly 5% of those treated with GLP-1 receptor agonists died compared with nearly 9% of those treated with metformin.
"Both medications demonstrate neuroprotective properties, such as reducing neuroinflammation and oxidative stress, improving insulin sensitivity, and enhancing cerebrovascular health, which likely contribute to their benefits in overall dementia," explain the researchers.
But unlike metformin, whose benefits primarily derive from systemic metabolic effects, GLP-1 receptor agonists exert direct central nervous system effects by crossing the blood-brain barrier, they add.
"However, the multifactorial nature of [vascular dementia], driven by cerebrovascular damage, such as small vessel disease and white matter lesions, poses significant challenges for pharmacological interventions targeting metabolic or neurodegenerative pathways," they continue.
This is an observational study, and as such, no firm conclusions can be drawn about cause and effect. And the researchers point out that the tracking period, while sufficient for observing dementia outcomes, may not fully capture long-term cognitive effects, especially given the progressive nature of Alzheimer's disease.
But they nevertheless conclude, "Given the severe societal, familial, and economic burden of diabetes-related dementia, these findings raise important considerations about the role of GLP-1 [receptor agonists] as first-line therapies in [type 2 diabetes] management.
"While further long-term studies are warranted to validate these results, integrating GLP-1 [receptor agonists] as primary therapeutic agents may represent a paradigm shift in preventing the cognitive complications of diabetes."

FDA Approves Ibtrozi (taletrectinib) for Advanced ROS1-Positive Non-Small Cell Lung Cancer
Nuvation Bio Inc. announced the U.S. Food and Drug Administration (FDA) approval of Ibtrozi (taletrectinib) for the treatment of adult patients with locally advanced or metastatic ROS1-positive (ROS1+) non-small cell lung cancer (NSCLC). Ibtrozi is a highly selective, next-generation oral ROS1 tyrosine kinase inhibitor (TKI) designed to address some of the outstanding challenges of treating ROS1+ NSCLC. It has demonstrated high response rates with durable benefit and intracranial activity and is generally well tolerated, providing a new treatment option for patients with advanced ROS1+ NSCLC.
“The FDA approval of Ibtrozi marks a major milestone in the evolution of targeted therapy for advanced ROS1-positive NSCLC,” said David Hung, M.D., Founder, President and Chief Executive Officer of Nuvation Bio. “We believe one of the greatest threats to ROS1-positive lung cancer patients is disease progression, especially in the first-line setting. In pivotal trials, Ibtrozi delivered high response rates with sustained durability—truly meaningful benefits for patients. With its clinically proven efficacy and safety profile, we believe Ibtrozi has the potential to become a new standard for what targeted therapies can achieve in this type of lung cancer. With approvals for Ibtrozi now in the U.S. and China, and additional global filings underway, we remain committed to delivering innovative therapies that help patients stay ahead of their disease.”
ROS1+ NSCLC is a rare and aggressive form of lung cancer, accounting for approximately 2% of new NSCLC cases, or about 3,000 new diagnoses of advanced disease annually in the U.S. The median age at diagnosis for patients with this type of lung cancer is approximately 50 years old, and the disease is more likely to occur in people who have never smoked. Brain metastases are common and a leading cause of disease progression and mortality in this population.
“For people living with advanced ROS1-positive lung cancer, who tend to be diagnosed at a younger age, having another treatment option can make a real difference for them and their loved ones,” said Janet Freeman-Daily, Co-Founder and President of The ROS1ders. “The approval of this new targeted therapy is a meaningful step forward for the advanced ROS1+ lung cancer community and offers hope for patients facing the added challenge of cancer spreading to the brain.”
The FDA approval of Ibtrozi is supported by one of the largest global clinical trial programs in ROS1+ NSCLC to date, with over 300 patients enrolled in the pivotal TRUST-I and TRUST-II studies.
In TRUST-I, Ibtrozi achieved a confirmed overall response rate (cORR) of 90% in TKI-naïve patients. These findings were reinforced by the TRUST-II results, with a cORR of 85% in TKI-naïve patients. The median duration of response (DOR) was not yet reached for either trial, based on a cutoff date that is nearly five months later than that of the pooled TRUST-I and TRUST-II analysis published in April in the Journal of Clinical Oncology. For TRUST-I, with a median follow-up for responses of 40 months, the longest DOR was observed at 46.9 months and ongoing. For TRUST-II, with a median follow-up for responses of 19 months, the longest DOR was observed at 30.4 months and ongoing as of October 2024. Given the single-arm nature of the TRUST clinical studies, median progression-free survival (PFS) is not provided in the label.
Across the pivotal studies, consistent results were also observed among patients who were previously treated with a ROS1 TKI (TKI-pretreated). In TRUST-I, treatment with Ibtrozi achieved a cORR of 52% and median DOR of 13.2 months for TKI-pretreated patients, with median follow-up for responses of 33 months. In TRUST-II, treatment with Ibtrozi achieved a cORR of 62%, and as of October 2024 the median DOR was 19.4 months in these patients, with a median follow-up for responses of 19 months.
Brain metastases are among the most common and devastating complications in advanced ROS1+ NSCLC. Ibtrozi was designed to penetrate the central nervous system (CNS) and has demonstrated consistent intracranial responses in patients with measurable brain metastases at baseline. An intracranial response was achieved in 73% of TKI-naive patients (11/15) and 63% of TKI-pretreated patients (15/24).
“Patients living with advanced ROS1+ non-small cell lung cancer and their healthcare providers are in need of new treatment options,” added Nathan Pennell, M.D., Ph.D., TRUST study investigator and Professor of Medicine at the Cleveland Clinic. “Ibtrozi’s durability of response and ability to effectively penetrate the brain, coupled with a well-characterized and manageable safety profile, further addresses these critical needs for patients. I believe this now-approved therapy offers providers and patients a promising new option for the treatment of advanced ROS1+ non-small cell lung cancer.” Dr. Pennell is a compensated member of Nuvation Bio’s advisory committee.
Ibtrozi was generally well-tolerated, with most adverse events being low grade, transient and manageable. Patients infrequently (7%) discontinued treatment due to treatment-emergent adverse events (TEAEs). The most common adverse reactions (≥20%) included diarrhea (64%), nausea (47%), vomiting (43%), dizziness (22%), rash (22%), constipation (21%), and fatigue (20%). Overall, the majority of CNS events were mild to moderate (~90%) and resolved within days, and dose modifications due to these events were low (~5%). Approximately 90% of reported cases of dizziness were Grade 1 (mild) and transient. Liver enzyme elevations (AST 87%/ALT 85%) and QT prolongation (19%) were manageable with standard monitoring and dose modifications. Ibtrozi is approved as a 600 mg once-daily oral dose, supported by a half-life of approximately 66 hours and broad tissue distribution, including the brain, enabling sustained systemic and CNS exposure.

FDA Approves Zusduri (mitomycin) for Recurrent Low-Grade Intermediate-Risk Non-Muscle Invasive Bladder Cancer
UroGen Pharma Ltd. announced the U.S. Food and Drug Administration (FDA) approval of Zusduri, the first and only FDA-approved medication for adults with recurrent LG-IR-NMIBC. Zusduri consists of mitomycin and sterile hydrogel, using UroGen’s proprietary sustained release RTGel® technology. Zusduri has been designed for potent tumor ablation. This landmark approval is based on the positive results from the Phase 3 ENVISION trial that demonstrated Zusduri delivers 78% complete response (CR) for patients at 3 months, and of those patients 79% remained event-free 12 months later.
“The approval of Zusduri represents a significant step forward for our company and for the treatment of recurrent LG-IR-NMIBC," said Liz Barrett, President and CEO of UroGen. "For the first time, the estimated 59,000 U.S. patients facing recurrent LG-IR-NMIBC each year have access to an FDA-approved medicine. This historic achievement is a bold leap forward in our mission to redefine uro-oncology and bring innovation to patients who need it most. We are deeply grateful to the FDA for their collaboration and to the investigators, patients, and caregivers whose commitment made this milestone possible. Their contributions have been essential in bringing meaningful innovation to the bladder cancer community.”
The existing standard of care for LG-IR-NMIBC is a surgical procedure typically performed under general anesthesia called transurethral resection of bladder tumor (TURBT). Due to high recurrence rates of LG-IR-NMIBC, repeat TURBTs may be necessary.
"Zusduri marks a breakthrough in uro-oncology, offering a new alternative for recurrent LG-IR-NMIBC patients who can live for many years with the disease but often endure multiple resections, under general anesthesia,” said Dr. Sandip Prasad, MD, M.Phil., Director of Genitourinary Surgical Oncology at Morristown Medical Center/Atlantic Health System, NJ, and principal investigator of the ENVISION trial. “For decades, TURBT has been the standard approach for bladder cancer treatment. That’s why innovative treatments like Zusduri are essential, especially for those adult patients with recurrent low-grade, intermediate-risk NMIBC.”
The most common (≥ 10%) adverse reactions, including laboratory abnormalities, that occurred in patients were increased creatinine, increased potassium, dysuria, decreased hemoglobin, increased aspartate aminotransferase, increased alanine aminotransferase, increased eosinophils, decreased lymphocytes, urinary tract infection, decreased neutrophils, and hematuria. Serious adverse reactions occurred in 12% of patients who received Zusduri, including, urinary retention (0.8%) and urethral stenosis (0.4%).

FDA Approves Symbravo (meloxicam and rizatriptan) for the Acute Treatment of Migraine with or without Aura in Adults
Richard B. Lipton, MD, Professor of Neurology and Director of the Montefiore Headache Center, Albert Einstein College of Medicine, commented, “A significant proportion of migraine patients experience inadequate efficacy with currently available acute treatments, leading to even greater suffering, and an increased risk of worsening of migraine pain and attack frequency. Results of multiple clinical trials demonstrate that Symbravo can provide rapid and long-lasting freedom from migraine pain, whether treatment is taken early in the attack while the pain is mild, or later in the attack when the pain may be severe. The approval of Symbravo is a long awaited and much welcomed advancement for clinicians and our patients, providing a new, meaningful treatment option.”
Stewart Tepper, MD, Clinical Professor of Neurology at the Geisel School of Medicine at Dartmouth and Vice President of the New England Institute for Neurology and Headache, said, “Migraine is a debilitating condition that affects millions of Americans. Unfortunately, many patients still struggle to find an option that effectively treats their attacks and is both safe and well tolerated, which creates a great need for new migraine medicines. Symbravo’s approval by the FDA provides a new medicine for physicians and patients that was designed to target key unmet needs in the migraine treatment space. The clinical data supporting its approval validates the additive benefit of Symbravo’s multi-mechanistic design and demonstrates its potential to make a meaningful difference for the migraine community.”
Susan Doughty, Executive Director of the Coalition for Headache and Migraine Patients (CHAMP), added, “Migraine is one of the most misunderstood and stigmatized neurological diseases, despite the fact that one in four households in the U.S. includes someone living with it. This widespread lack of understanding creates unnecessary barriers for individuals seeking proper diagnosis, care, and treatment. CHAMP, alongside our 20 plus dedicated coalition organizations and patient advocates, is committed to empowering the migraine community by providing education, reducing stigma, and advocating for fair and equitable access to treatment options. The approval of Symbravo as a new acute treatment for migraine is an important step forward, offering a new option for people seeking relief. We also see this moment as an opportunity to continue to shine a bright light on migraine, fostering greater awareness and helping to dismantle the stigma that so often surrounds this disease.”
The FDA approval of Symbravo is based on the results of the Phase 3 MOMENTUM trial that treated migraine of moderate and severe pain intensity, the Phase 3 INTERCEPT trial that treated migraine when the initial pain was mild, and the Phase 3 MOVEMENT long-term open label safety trial. In this comprehensive clinical program, over 21,000 migraine attacks were treated with Symbravo.
In the MOMENTUM trial, Symbravo demonstrated a statistically significantly greater percentage of patients achieving pain freedom and freedom from their most bothersome symptom (photophobia, phonophobia, nausea) 2 hours after dosing compared to placebo. Symbravo also demonstrated statistical superiority for pain relief (reduction of moderate or severe pain to no pain or mild pain) and the ability to perform normal daily activities. The benefits of pain freedom at 2 hours were sustained through 24 and 48 hours for many patients. In a head-to-head comparison, Symbravo demonstrated statistically significant superiority compared to rizatriptan on sustained pain freedom from 2 to 24 hours. Notably, these benefits were seen with only a single dose of Symbravo. In the MOMENTUM trial, 77% of patients treated with Symbravo did not require rescue medication within 24 hours post dose.
In the INTERCEPT trial, Symbravo demonstrated a statistically significantly greater percentage of patients achieving pain freedom and freedom from their most bothersome symptom (photophobia, phonophobia, nausea) 2 hours after dosing compared to placebo. The benefits of pain freedom at 2 hours were sustained through 24 and 48 hours for many patients. Notably, these benefits were seen with only a single dose of Symbravo. In the INTERCEPT trial, 85% of patients treated with Symbravo did not require rescue medication within 24 hours post dose.
The most common adverse reactions (≥1% and greater than placebo) in the controlled studies were somnolence and dizziness, being reported each in 2% and 1% of patients in the Symbravo and placebo arms, respectively. The long-term safety of Symbravo was demonstrated in the MOVEMENT trial, which assessed 706 patients dosing intermittently for up to 12 months and treating at least 2 migraines per month with Symbravo.
Symbravo is engineered with Axsome’s patented MoSEICTM (Molecular Solubility Enhanced Inclusion Complex) rapid absorption technology. MoSEIC results in a five times faster median time to maximum plasma concentration for meloxicam while maintaining a long plasma half-life, enabling meloxicam’s use as a new molecular entity for the acute treatment of migraine. Symbravo is protected by a robust patent estate extending out to at least 2040.

About Grafapex (treosulfan) for injection
Grafapex (treosulfan) for injection, an alkylating agent, is indicated in combination with fludarabine as a preparative regimen for allogeneic hematopoietic stem cell transplantation (alloHSCT) in adult and pediatric patients one year of age and older with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). Grafapex holds Orphan Drug Designation under the Orphan Drug Act, meaning that the product will benefit from a seven-year period of regulatory exclusivity in the FDA-approved indication.
Full prescribing information for Grafapex will be available on the Drugs@FDA drug database at www.fda.gov.
Efficacy was evaluated in MC-FludT.14/L Trial II (NCT00822393), a randomized active-controlled trial comparing treosulfan to busulfan with fludarabine as a preparative regimen for allogeneic transplantation. Eligible patients included adults 18 to 70 years old with AML or MDS, Karnofsky performance status ≥60%, and age ≥50 years or hematopoietic cell transplantation comorbidity index [HCTCI] score >2. There were 570 patients randomized to treosulfan (n=280) or busulfan (n=290).
The major efficacy outcome measure was overall survival (OS), defined as the time from randomization until death from any cause. The hazard ratio for OS (stratified by donor type and risk group) compared to busulfan was 0.67 (95% CI: 0.51, 0.90) in the randomized population, 0.73 (95% CI: 0.51, 1.06) in patients with AML, and 0.64 (95% CI: 0.40, 1.02) in patients with MDS.
The most common adverse reactions (≥20%) were musculoskeletal pain, stomatitis, pyrexia, nausea, edema, infection, and vomiting. Selected Grade 3 or 4 nonhematological laboratory abnormalities were increased GGT (gamma-glutamyl transferase), increased bilirubin, increased ALT (alanine aminotransferase), increased AST (aspartate aminotransferase), and increased creatinine.
The recommended treosulfan dose is 10 g/m2 daily on days -4, -3, and -2 in combination with fludarabine 30 mg/m2 daily on days -6, -5, -4, -3, and -2, and allogeneic hematopoietic stem cell infusion on day 0.

FDA Approves Arbli (losartan potassium) Oral Suspension as the First Ready-to-Use Oral Liquid Losartan in the U.S.
In continuation of my update on losartan
Scienture Holdings, Inc. announced the U.S. Food and Drug Administration (FDA) approval of SCN-102, one of the products being developed by Scienture, LLC, a wholly owned subsidiary of Scienture Holdings, Inc., with the brand name Arbli (losartan potassium) Oral Suspension, 10 mg/mL. Arbli is meant for the treatment of hypertension in patients greater than 6 years old, for the reduction of risk of stroke in patients with hypertension and left ventricular hypertrophy and for the treatment of diabetic nephropathy in certain patients with type 2 diabetes. Arbli is the first and only FDA approved ready-to-use oral liquid losartan in the U.S. market.
Arbli is a novel proprietary formulation of losartan, a proven therapy for treating hypertension, which provides a tailored approach to patients that require or prefer an oral liquid option of losartan. Appropriate dosing is now easier, safe and effective, while providing the assurance of quality as an FDA-approved product. Arbli provides a safe and convenient option to patients requiring a liquid formulation and addresses the intrinsic risks associated with potential inconsistencies in the process of crushing tablets to extemporaneously compound losartan prescriptions. Arbli has two issued patents from the USPTO, which are also expected to be listed in the FDA Orangebook.
Losartan is classified as an angiotensin receptor blocker (ARB) for treating hypertension and is one of the highest prescribed molecules for this indication. Current products in the market containing losartan are available only as oral solids, which can be further compounded to a liquid formulation. Arbli is the first liquid formulation of losartan on the market that does not require compounding and has reduced dosing volume and long-term shelf life at room temperature storage. IQVIA data (MAT December 2024) indicates a total annual sales of approximately $292 million and a prescription volume of 68 million (TRx) for losartan in the US market.
“The approval of Arbli exemplifies our deep commitment to develop high value products that address unique and underserved patient needs. A significant number of patients can benefit from a safe and efficacious ready-to-use oral liquid formulation of losartan. We are excited with the approval of our first brand product which is part of our upcoming pipeline of novel specialty products,” remarked Shankar Hariharan, CEO of Scienture, LLC.
“We are pleased to bring to market, Arbli, a transformative therapy option containing losartan, one of the most widely prescribed molecules in its class, to patients, caregivers and healthcare professionals (HCPs). We expect to commercially launch and make Arbli available to patients in the U.S. in Q3 2025,” said Narasimhan Mani, President of Scienture, LLC.
“This announcement is extremely exciting and is a clear demonstration of the value Scienture, LLC brings to the combined company and its shareholders,” said Suren Ajjarapu, Chairman of the Board, Scienture Holdings, Inc.

FDA Approves HemiClor (chlorthalidone) for the Treatment of Hypertension
PRM Pharma, LLC announced the U.S. Food and Drug Administration (FDA) approval of HemiClor (12.5 mg chlorthalidone) tablets for the treatment of hypertension in adults, to lower blood pressure.
Chlorthalidone, a thiazide-like diuretic, has been studied extensively over several decades in the treatment of hypertension. It is recognized in the 2017 ACC/AHA Guideline for the Prevention, Detection, Evaluation and Management of High Blood Pressure in Adults as the preferred diuretic based on its prolonged half-life and evidence of cardiovascular outcome benefits.1 Landmark studies such as the ALLHAT and SHEP trials, sponsored by the National Heart, Lung, and Blood Institute, demonstrated that stepped-care treatment strategies—which often began with 12.5 mg of chlorthalidone—were effective in reducing the risk of cardiovascular events.2,3 These findings support the use of 12.5 mg as the recommended starting dose in current hypertension treatment guidelines, either to initiate antihypertensive therapy or to serve as addon therapy when additional blood pressure reduction is needed.1,4
HemiClor now provides U.S. patients and healthcare professionals access to a 12.5 mg chlorthalidone tablet formulation that aligns with guideline recommendations. Until now, only higher-dose chlorthalidone tablets (25 mg and 50 mg) have been available in the U.S. This new low-dose option may help clinicians better individualize therapy and potentially reduce the risk of dose-related side effects. As noted in the approved prescribing information, metabolic adverse effects such as hypokalemia and hyperuricemia are dose-related; thus, a lower starting dose may help mitigate these risks when initiating treatment.5
“Chlorthalidone has played a key role in hypertension treatment strategies for decades,” said William B. White, M.D., Professor Emeritus at the University of Connecticut School of Medicine and past president of the American Society of Hypertension. “Having access to a 12.5 mg dose in the U.S. may offer clinicians additional flexibility when initiating therapy and aligns with current treatment recommendations for many adult patients with stage 1 or stage 2 hypertension.”
Joseph T. McDevitt, President and CEO of PRM Pharma, LLC, added, “We are proud to introduce HemiClor as a new treatment option for adults with hypertension. Our mission is to address unmet clinical needs by developing low-dose pharmaceutical products that support evidence-based care. Lower effective doses may offer a more individualized approach to initiating therapies, particularly for elderly patients who are more susceptible to dose-related adverse effects.”
HemiClor (12.5 mg chlorthalidone tablets) is expected to be available in pharmacies nationwide beginning in May 2025.
Indication and Usage
HemiClor (chlorthalidone) is indicated for the treatment of hypertension to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been demonstrated in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes, including chlorthalidone.

FDA Approves Blujepa (gepotidacin) for the Treatment of Uncomplicated Urinary Tract Infections
GSK plc announced the US Food and Drug Administration (FDA) approval of Blujepa (gepotidacin) for the treatment of female adults (≥40 kg) and paediatric patients (≥12 years, ≥40 kg) with uncomplicated urinary tract infections (uUTIs) caused by the following susceptible microorganisms: Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii complex, Staphylococcus saprophyticus and Enterococcus faecalis.
Discovered by GSK scientists, Blujepa is a first-in-class oral antibiotic with a novel mechanism of action that is part of GSK’s infectious diseases portfolio.
Tony Wood, Chief Scientific Officer, GSK, said: “The approval of Blujepa is a crucial milestone with uUTIs among the most common infections in women. We are proud to have developed Blujepa, the first in a new class of oral antibiotics for uUTIs in nearly three decades, and to bring another option to patients given recurrent infections and rising rates of resistance to existing treatments.”
uUTIs are the most common infection in women, impacting up to 16 million women in the US annually.1-4 Over half of all women are affected by uUTI in their lifetime,5 with approximately 30% suffering from at least one recurrent episode which can cause significant patient burden, including discomfort and restriction of daily activities.6 New treatments are needed as the number of uUTIs caused by drug-resistant bacteria is increasing which can result in higher treatment failure rates.7
Thomas Hooton, MD, Professor of Clinical Medicine, University of Miami School of Medicine said: “For many, uUTIs can be a burden that severely impacts daily life. With an increasing number of patients experiencing recurrent infections, there remains a clear need for continued research of antimicrobials to help address ongoing patient challenges and the strain on healthcare systems.”
The approval is based on positive results from the pivotal phase III EAGLE-2 and EAGLE-3 trials which demonstrated non-inferiority to nitrofurantoin, one of the leading current standard of care options for uUTI, in female adults (≥40 kg) and paediatric patients (≥12 years, ≥40 kg) with a confirmed uUTI. In EAGLE-2, Blujepa demonstrated non-inferiority in therapeutic success which occurred in 50.6% (162/320) of participants compared to 47.0% (135/287) for nitrofurantoin (covariate-adjusted treatment difference 4.3%, 95% CI (-3.6, 12.1)). In EAGLE-3, Blujepa demonstrated statistically significant superiority versus nitrofurantoin (one-sided p-value 0.0003). Therapeutic success occurred in 58.5% (162/277) of participants compared to 43.6% (115/264) for nitrofurantoin (covariate-adjusted treatment difference 14.6%, 95% CI (6.4, 22.8)).
The safety and tolerability profile of Blujepa in the EAGLE-2 and EAGLE-3 phase III trials was consistent with previous trials. The most commonly reported adverse events (AEs) in Blujepa participants were gastrointestinal (GI). Diarrhoea was the most common (16% of participants), followed by nausea (9%). Of the participants who reported GI AEs in the Blujepa group, the most common maximum severity was mild (69% Grade 1) and moderate (28% Grade 2). Participants with Grade 3 GI events accounted for 3% of all patients with GI events and occurred in <1% of all participants. There was one drug-related serious adverse event in each treatment arm (Blujepa and nitrofurantoin) across the two trials.
