NovelMed Therapeutics, Inc.

--- Precision Bb Targeting, Robust Efficacy, Transfusion Independence, Excellent Safety in Phase II PNH Study, and Subcutaneous Administration Key Highlights: Monotherapy and Clinical Outcomes The 12-16-week open-label study evaluated Ruxoprubart as monotherapy in treatment-naïve PNH patients. Key findings include: Hemoglobin (Hb) Improvement: Hemoglobin levels increased by 1.5–2.7 g/dL, with an average rise of ~2.13 g/dL during weekly dosing, reflecting meaningful correction from the severely depressed baseline common in untreated PNH. Complete Transfusion Independence: Throughout the weekly dosing period, 100% of patients required no blood transfusions, demonstrating effective control of hemolysis and clinically meaningful correction of anemia. PNH Red Blood Cells (RBCs) Survival & Expansion: PNH RBC populations expanded to up to 94% of their maximum level. This is consistent with near-complete suppression of ongoing complement-mediated hemolysis, a core driver of anemia and fatigue. Biochemical Control (LDH): Lactate Dehydrogenase (LDH) levels were significantly reduced, reflecting biochemical control of intravascular hemolysis (IVH). Quality-of-Life (QoL) Gains: Patient‑reported outcomes, including the Functional Assessment of Chronic Illness Therapy (FACIT) and the European Organization for Research and Treatment of Cancer (EORTC) questionnaires, showed meaningful improvements across fatigue, pain, and overall functional capacity. Safety and Tolerability: The therapy was well-tolerated with no drug-related Adverse Events (AEs) or Serious Adverse Events (SAEs) observed. Orphan Drug Designation: Ruxoprubart holds U.S. FDA Orphan Drug Designation (ODD) for PNH, highlighting its potential to address this rare and life-threatening condition. CLEVELAND, March 09, 2026 (GLOBE NEWSWIRE) -- NovelMed Therapeutics Inc., a clinical-stage biopharmaceutical company specializing in alternative pathway (AP) complement-mediated therapies, today announced two major milestones in the clinical development of Ruxoprubart (NM8074) for Paroxysmal Nocturnal Hemoglobinuria (PNH). The company has received regulatory clearance to initiate a Phase II study for the subcutaneous (SC) route of administration, designed as a convenient, weekly, self-administered injection. Concurrently, NovelMed reported the full results of its Phase II intravenous (IV) monotherapy study in treatment-naïve adult patients with PNH. The study met all efficacy endpoints, including significant hemoglobin improvement and complete transfusion avoidance, with an exceptional safety profile. “These milestones validate both our clinical progress and our development strategy,” said Dr. Rekha Bansal, Chief Executive Officer of NovelMed. “Regulatory clearance of the SC route represents the next logical step toward a patient-friendly treatment option, while our monotherapy data demonstrate the strong, consistent efficacy and tolerability of targeting Bb. We are now progressing into the next phase of clinical development.” Advancing Two Complementary Tracks in PNH NovelMed is progressing Ruxoprubart through two distinct delivery methods to maximize patient access and convenience: Subcutaneous (SC) Administration: Cleared for Phase II Development The regulatory agency has cleared the SC route of administration, enabling a planned, weekly self-injection regimen at home. SC trials are planned but have not yet been initiated. This approach is expected to reduce patient and caregiver burden by eliminating the need for IV infusions in a clinical setting. Intravenous (IV) Monotherapy: Treatment-Naïve PNH Patients The successful completion of the intravenous Phase II study establishes Ruxoprubart as a potent monotherapy capable of addressing the core drivers of PNH without adjunctive treatment. “Ruxoprubart has proven its potential as a definitive monotherapy, delivering exceptional efficacy without compromise,” said Mr. Alex Kumar, Chief Strategy Advisor. “Coupled with FDA Orphan Drug Designation status and regulatory clearance for SC dosing, we have a clear, accelerated path forward. NovelMed is now uniquely positioned to lead the next generation of precision complement therapeutics on a global scale.” Precision Targeting: The Bb Mechanism and Differentiation PNH is an AP-driven hemolytic disorder. Ruxoprubart (NM8074) is a first-in-class monoclonal antibody engineered for precision targeting of Bb, the proteolytically activated catalytic fragment generated upon AP activation. By binding Bb rather than native Factor B, Ruxoprubart delivers precise AP-selective inhibition while preserving the Classical Pathway (CP), which remains essential for protecting patients from infections. “The Phase II intravenous results demonstrate a clinical efficacy and safety pro aligns well with FDA expectations for monotherapy development in PNH,” said Mr. Robert Bard. “With the SC route now cleared for evaluation under our Phase II program, we are advancing along a well-defined regulatory path. This progress brings us closer to enabling patient-friendly, self-administered treatment options supported by a mechanism designed for pathway-selective precision.” Competitive Landscape at a Glance Ruxoprubart (NovelMed): Targets activated Bb (FDA Orphan Drug Designation Holder). A precision monotherapy that provides selective AP inhibition while preserving the CP for host defense. Soliris® / Ultomiris® (AstraZeneca): Targets C5. A distal blocker of both AP and CP that fails to prevent C3b deposition, which leads to persistent anemia. Empaveli® / Syfovre® (Apellis): Targets C3. A proximal blocker that provides broad inhibition of both AP and CP, addressing C3b-mediated EVH but impacting overall complement surveillance. Fabhalta® (Novartis): Targets native Factor B. A proximal blocker that lacks precision by targeting the native protein rather than the proteolytically activated Bb fragment. Voydeya® (AstraZeneca): Targets Factor D. A proximal blocker, strictly approved as an add-on therapy to C5 inhibitors rather than a standalone monotherapy. Key Pillars of the Regulatory Strategy Monotherapy Treatment: Ruxoprubart has demonstrated the ability to meet all primary endpoints as a standalone treatment. This allows for a more direct regulatory path, as the drug does not need to be tested or approved alongside existing C5 inhibitors to prove its value. Subcutaneous (SC) Administration: The regulatory clearance for the SC route is a major milestone. Having passed rigorous safety and manufacturing reviews, Ruxoprubart is now cleared for human trials using at-home injections. This shifts the treatment model from clinical IV infusions to a more convenient, patient-controlled approach. Precision Targeting of the Bb: Ruxoprubart selectively targets the AP while keeping the CP intact. This "selective precision" is designed to maintain the body’s natural ability to fight infections, a differentiated safety pro supports the case for expedited regulatory designations like Fast Track or Breakthrough Therapy. Figure. Complement-mediated destruction of red blood cells in paroxysmal nocturnal hemoglobinuria (PNH). About Paroxysmal Nocturnal Hemoglobinuria (PNH) Paroxysmal Nocturnal Hemoglobinuria (PNH) is a rare, acquired, and life-threatening hematologic disorder caused by a somatic mutation in the PIGA gene. This mutation results in the deficiency of GPI-anchored complement regulatory proteins, specifically CD55 and CD59, which act as protective shields for RBCs. Without these proteins, RBCs are highly vulnerable to persistent attack by the AP of the complement system, leading to chronic intravascular and extravascular hemolysis. This ongoing destruction manifests clinically as severe anemia, dangerously elevated Lactate Dehydrogenase (LDH) levels, and a significantly increased risk of life-threatening thrombosis and renal impairment. Effective treatment is measured by stabilization of hemoglobin and the expansion of the PNH RBC clone, indicating that these cells are successfully protected from complement-mediated attack. About NovelMed Therapeutics NovelMed Therapeutics Inc. is a clinical-stage biopharmaceutical company dedicated to developing next-generation immunotherapies that selectively target the complement AP. The company has pioneered a site-specific approach by engineering monoclonal antibodies, such as its lead candidates Ruxoprubart (NM8074) and NM5072, to target proteolytically activated fragments, such as Bb, rather than native proteins. This precision enables potent blockade of the disease-driving AP while intentionally preserving the CP’s critical role in host defense and immune surveillance. Supported by a robust portfolio of intellectual property and promising Phase II data, NovelMed is advancing a differentiated pipeline of first-in-class biologics designed to achieve durable clinical outcomes without compromising the patient’s ability to fight infections. Strategic Partnership Opportunity Following the achievement of 100% transfusion avoidance in its Phase II monotherapy study and the recent regulatory clearance for SC administration, NovelMed is actively pursuing a strategic partnership to propel Ruxoprubart through late-stage global development. This program is exceptionally well-positioned for expansion, supported by U.S. FDA Orphan Drug Designation (ODD) and a validated, precision mechanism that addresses significant unmet needs in the PNH market. NovelMed seeks a partner with extensive clinical and commercial expertise to accelerate the regulatory path towards approval and support the global launch of this patient-friendly, self-administered therapy. By combining NovelMed’s innovative science with a partner's scale, the company aims to redefine the treatment landscape for rare complement-mediated diseases.

As more patients and providers seek disease-modifying options, FILSPARI is well-positioned to capture substantial market share, especially with favorable long-term data. LAS VEGAS, May 27, 2025 /PRNewswire/ -- DelveInsight's " FILSPARI Market Size, Forecast, and Market Insight Report" highlights the details around FILSPARI, the first and only oral, once-daily, non-immunosuppressive therapy approved in both the US and Europe for IgAN. The report provides product descriptions, patent details, and competitor products (marketed and emerging therapies) of FILSPARI. The report also highlights the historical and forecasted sales from 2020 to 2034 segmented into 7MM [the United States, the EU4 (Germany, France, Italy, and Spain), the United Kingdom, and Japan]. Travere Therapeutics' FILSPARI (sparsentan) Overview FILSPARI (sparsentan) is a once-daily oral treatment that uniquely targets two key pathways, endothelin-1 and angiotensin II (also known as DEARA), in the progression of IgA nephropathy. It is the first approved non-immunosuppressive therapy for this condition. Endothelin-1 and angiotensin II contribute to kidney function decline by promoting inflammation and fibrosis, altering podocyte structure, causing podocyte loss, and increasing the permeability of the glomerular filtration barrier. Additionally, both are vasoconstrictors that narrow blood vessels and raise pressure in the glomeruli. The drug received accelerated approval based on its ability to reduce proteinuria. Due to potential safety concerns, it is distributed under the FILSPARI Risk Evaluation and Mitigation Strategy (REMS) program. In Europe, it is marketed by CSL Vifor, and in Japan by Renalys Pharma. Results from the registration-enabling study are expected in the second half of 2025. Learn more about FILSPARI projected market size for IgAN @ FILSPARI IgA Nephropathy IgA nephropathy (IgAN) is an autoimmune disorder that disrupts kidney function by damaging the small blood vessels responsible for filtration. This damage is caused by an abnormal protein that harms the glomeruli, the kidneys' main filtering units.

In February 2023, the US FDA granted accelerated approval to FILSPARI (sparsentan) to reduce proteinuria in adults with primary IgAN at risk of rapid progression, with priority review. Discover how FILSPARI is shaping the IgAN treatment landscape @ FILSPARI IgAN FILSPARI Market Dynamics FILSPARI, developed by Travere Therapeutics, represents a significant advancement in the treatment of IgA Nephropathy, a rare and chronic autoimmune kidney disease. Approved under the FDA's accelerated approval program in early 2023, FILSPARI is the first non-immunosuppressive therapy specifically targeting proteinuria in IgAN. It is a dual endothelin angiotensin receptor antagonist (DEARA), a novel mechanism that distinguishes it from conventional RAAS inhibitors. Its market entry has been notable for both its scientific innovation and potential to reshape the standard of care for IgAN, particularly in patients at high risk of progression to end-stage kidney disease (ESKD). The market dynamics are influenced by multiple factors, including the unmet need in IgAN, the orphan drug designation, and the limited competition in the space. Prior to FILSPARI's launch, treatment was largely supportive, focusing on blood pressure control and proteinuria reduction via ACE inhibitors or ARBs. FILSPARI's ability to deliver greater proteinuria reduction without the side effects associated with corticosteroids or immunosuppressants provides a compelling clinical and commercial value proposition. Competition is evolving, with several companies advancing novel IgAN therapeutics. Calliditas Therapeutics' TARPEYO (budesonide) was approved ahead of FILSPARI for a similar indication, but works through a corticosteroid pathway. Other players are also advancing programs, suggesting the market could become more segmented based on patient profile and mechanism of action. FILSPARI's differentiated profile, especially its dual-acting mechanism and oral administration, positions it favorably among nephrologists and specialists, but maintaining this edge will require strong real-world evidence and ongoing clinical data. From a market access and adoption standpoint, Travere has made early efforts in physician education, patient support programs, and collaboration with nephrology groups to accelerate uptake. However, broader adoption will depend on securing favorable formulary placements, long-term safety data, and sustained efficacy in delaying disease progression. As I gAN awareness grows and diagnosis rates improve through genetic and biomarker testing, the addressable patient population may expand, offering a significant growth opportunity for FILSPARI over the next 5–10 years.

--- Ruxoprubart (NM8074) met all clinical endpoints, offering a safe, differentiated treatment for Paroxysmal Nocturnal Hemoglobinuria (PNH). Paroxysmal Nocturnal Hemoglobinuria (PNH) is a rare hematological (Blood) disorder. Regulatory approval for the Phase II trial in PNH subjects was granted based on the safety profile of healthy subjects in the Phase I trial. Interim results from this 12-subject, three-month, multi-dose Phase II efficacy trial are compelling. The drug was safe and well-tolerated in all treated PNH subjects with expected safety & efficacy, meeting all clinical endpoints with no reported side effects. In this efficacy trial, Ruxoprubart: Protected PNH Red Blood cells against lysis and enabled complete transfusion avoidance, meeting the primary endpoint. Increased hemoglobin levels above baseline by 1.4 to 2.0 g/dL in most subjects, with some showing intra-subject hemoglobin increase of 1.5 to 4.3 g/dL, exceeding the threshold set for the primary endpoint. An average hemoglobin increase of >1.6 g/dL was observed across the cohort from baseline to the end of the treatment period. Reduced LDH levels to baseline, meeting the primary efficacy endpoint. Significantly increased PNH Type III clone size by protecting PNH Red Blood Cells from complement-mediated lysis. Allowed normal pathogenic clearance in all treated PNH subjects, as infection cleared as expected. The regulatory agency has recently approved a once-weekly subcutaneous protocol for Ruxoprubart — allowing for self-administration and offering a distinct advantage over Apellis, which requires twice-weekly dosing. Ruxoprubart effectively inhibited the Alternative Pathway (AP) without affecting the Classical Pathway (CP) in the trial. More importantly, the FDA has granted Orphan Drug Designation (ODD) to Ruxoprubart for treating PNH. A Breakthrough Therapy Designation (BTD) application for Ruxoprubart in PNH will soon be filed for FDA review. Ruxoprubart is set to be developed as a novel treatment for several complement-mediated disorders, including but not limited to renal, hematological, dermatological, and ocular diseases. May 19, 2025 -- NovelMed is pleased to announce positive 12-week interim results from the ongoing multi-dose Phase II trial of Ruxoprubart, a novel complement-targeting immunotherapy, in adult patients with Paroxysmal Nocturnal Hemoglobinuria (PNH). These interim data demonstrate that Ruxoprubart, administered as monotherapy, was safe, well-tolerated, and met all primary efficacy endpoints. Ruxoprubart achieved transfusion avoidance, increased hemoglobin levels, reduced LDH, and increased PNH clone size — key outcomes that contributed to improved disease control and enhanced quality of life for PNH patients. “The promising interim results from our Phase II PNH study solidify Ruxoprubart as a novel treatment for patients with advanced hematological conditions, offering hope where existing therapies fall short. This achievement not only underscores our commitment to advancing Ruxoprubart, an immunotherapy for PNH, but also marks a significant step toward addressing critical unmet needs within this patient population," said Dr. Rekha Bansal, CEO. "I extend my sincere gratitude to the PNH subjects and investigators whose dedication has been instrumental in this success. We are eager to present our findings to regulatory authorities and proceed with the Phase III trial." Ruxoprubart works by binding to Bb and selectively inhibiting the protease activity of the Alternative Pathway C3 convertase, while preserving the Classical Pathway. By acting proximally in the Alternative Pathway, Ruxoprubart provides complete control over both intravascular and extravascular hemolysis, resulting in marked increases in hemoglobin levels observed in this trial. These findings support the drug’s advancement as a novel, next-generation immunotherapy for the treatment of PNH and a broad range of hematological, renal, inflammatory, and ocular diseases. “We are excited to announce that our Alternative Pathway strategy for treating PNH is delivering exceptional results,” said Mr. Alex Kumar, Chief Strategy Advisor at NovelMed. “These data reinforce our confidence as we look forward to working with the regulatory agency to bring Ruxoprubart to PNH patients without delay. Our mission is to transform the lives of chronically ill patients for whom an ideal treatment has yet to be discovered.” This Phase II trial was initiated following the successful completion of a Phase I study involving 40 (forty) healthy volunteers. Ruxoprubart was well tolerated across all dose levels, ranging from 0.3 to 20 mg/kg, with no safety concerns. The drug demonstrated selective inhibition of the Alternative Pathway through Bb binding, without affecting the Classical Pathway. These promising safety findings paved the way for regulatory approval to initiate a Phase II study in patients with PNH. This ongoing 12-week clinical trial of Ruxoprubart is an open-label, multi-dose study in treatment-naïve adult subjects with PNH. The primary objectives are to evaluate the safety, tolerability, and efficacy of Ruxoprubart as a monotherapy in the Alternative Pathway-mediated lysis of Red Blood Cells. To date, 10 out of 12 PNH subjects have completed the study. Subjects 11 & 12 have been enrolled to complete the two-cohort trial. Interim results confirm that Ruxoprubart achieved all primary efficacy endpoints, delivering sustained clinical benefit in PNH. The primary efficacy endpoints include: Transfusion Avoidance: PNH patients typically require multiple blood transfusions to maintain normal hemoglobin levels. Ruxoprubart effectively protected PNH Type III cells from Alternative Pathway-mediated destruction, resulting in complete transfusion avoidance and successfully meeting the primary efficacy endpoint. Hemoglobin Increase: PNH patients experience reduced hemoglobin levels, leading to severe anemia. Ruxoprubart increased hemoglobin levels above baseline by 1.4 to 2.0 g/dL in most subjects, with some showing intra-subject increases ranging from 1.5 to 4.3 g/dL, surpassing the efficacy threshold defined for the primary endpoint. An average increase of >1.6 g/dL in hemoglobin was observed across the cohort from the beginning to the end of the treatment period. LDH Reduction: PNH patients experience severe lysis of Red Blood Cells (RBCs), leading to elevated lactate dehydrogenase (LDH) levels. By controlling complement-mediated hemolysis, Ruxoprubart reduced LDH levels to baseline, achieving the primary efficacy endpoint. Preservation of PNH Cells: Continuous lysis of Red Blood Cells in PNH leads to a dramatic reduction in total RBC count, often exceeding 80 to 90%. By effectively preventing this lysis, Ruxoprubart significantly preserved PNH cells, resulting in a substantial increase in the total PNH clone size and hemoglobin, successfully meeting the primary efficacy endpoint. Pathogenic Clearance: As expected, Ruxoprubart facilitated effective pathogenic clearance across all treated PNH subjects. In summary, the observed changes in efficacy parameters support the drug's mechanism of action and validate Ruxoprubart’s potential as a highly effective monotherapy for PNH. “We are thrilled to share these data, which demonstrate the potential of Ruxoprubart in advanced PNH, and look forward to working with regulatory authorities to bring this new immunotherapy to this patient community,” said Mr. Robert Bard, Vice President of Regulatory Affairs at NovelMed. “It’s very clear that we are on a promising path with exciting Phase II data in this serious hematological disorder.” PNH is a rare, acquired hematologic disorder in which Red Blood Cells lack protective surface proteins due to a mutation in the phosphatidylinositol glycan class A (PIGA) gene, leaving them vulnerable to complement-mediated destruction. In healthy individuals, Type I RBCs express complement regulatory proteins and are fully protected from complement-mediated destruction. In contrast, PNH patients have a significant percentage of Type III RBCs, which completely lack these protective proteins and are therefore highly susceptible to Alternative Pathway-mediated lysis. PNH is primarily an Alternative Pathway-mediated disease, with no involvement of the Classical or Lectin pathways in its pathology. Key laboratory markers indicative of disease progression include reduced Type III Red Blood Cells, low hemoglobin, elevated lactate dehydrogenase (LDH), and an increased need for blood transfusions. These markers reflect the underlying hemolytic anemia, which in turn leads to debilitating symptoms such as chronic fatigue, pain, jaundice, and organ damage. As the disease progresses, it significantly affects the patient’s quality of life and can ultimately result in life-threatening complications and death if not properly managed. While Soliris® (eculizumab) is the current FDA-approved standard of care for PNH – administered via intravenous infusion to provide C5 blockade – clinical limitations persist. Up to 88% of Soliris-treated patients continue to experience persistent anemia, with more than one-third of them requiring blood transfusions at least once every year. Despite its effectiveness in some patients, Soliris does not fully address the needs of many patients, as a significant proportion remain anemic, fatigued, and require blood transfusions, highlighting the need for specific, effective, and comprehensive therapies. Nearly all FDA-approved therapies for PNH and other complement-mediated disorders, oral or intravenous, suffer from the well-documented Black Box warning label because of the broad immunosuppression of the Classical Pathway, elevating the risk of life-threatening infections. Ruxoprubart offers a selective, upstream, and targeted approach to Alternative Pathway inhibition, without compromising the Classical Pathway, offering the best-in-class novel therapy. These attributes position Ruxoprubart as a safer and more effective treatment for patients with PNH. Ruxoprubart, an engineered human immunoglobulin, exhibits dual specificity: 1) it blocks only the Alternative Pathway, dysregulated by the disease, and 2) it binds Bb which has no binding to Factor B. Ruxoprubart met all primary endpoints in the interim evaluation of the ongoing Phase II clinical trial in PNH, positioning it as the first immunotherapy in this indication with the potential for approval without a Black Box warning. This immunotherapy has demonstrated a safe and well-tolerated profile across all five cohorts in the Phase I trial, including the highest dose of 20 mg/kg. Our findings confirm that the drug selectively blocks the Alternative Pathway. This differentiated, novel mechanism sets Ruxoprubart apart from other complement blockers (Soliris®, Ultomiris®, Empaveli®, Voydeya®, and Fabhalta®) currently approved or in development worldwide. Voydeya®, which received FDA approval in 2024 as a combination therapy, was developed by Achillion and acquired by AstraZeneca for $930 million. Despite its limited clinical efficacy, Voydeya®'s reliance on co-administration with a C5 inhibitor restricts its potential as a standalone therapy. Unlike Fabhalta®, which targets Factor B, Ruxoprubart (NM8074) binds to Bb, which is generated only upon activation of the Alternative Pathway, offering a unique mechanism of action as monotherapy. As a novel monotherapy with a unique, upstream, and pathway-specific mechanism, Ruxoprubart is emerging as a best-in-class candidate for the treatment of PNH and numerous complement-mediated diseases. NovelMed is a clinical-stage biopharmaceutical company dedicated to developing innovative novel biologics (immunotherapies) to treat a wide range of complement-mediated diseases. NovelMed proudly leads the development of Alternative Pathway-specific antibodies (NM8074, NM5072, and NM8070) to address a wide range of chronic complement-mediated disorders. The company is actively conducting a Phase II clinical trial in treatment-naïve PNH subjects to expedite the availability of this promising treatment. Additionally, the FDA has approved Phase II studies for several rare diseases, including but not limited to Atypical Hemolytic Uremic Syndrome (aHUS), C3 Glomerulopathy (C3G), IgA Nephropathy (IgAN), ANCA-Associated Vasculitis (AAV), and Dermatomyositis (DM).
