NM32 is a first-in-class half-life-enhanced T-cell engager targeting ROR1, a tumor associated antigen with broad expression in solid tumors and hematological malignancies Low molecular weight of NM32 allows to efficiently achieve higher tumor concentrations than larger immunoglobulin G molecules, the current standard format for CD3 engagers HORGEN, Switzerland, Oct. 30, 2024 (GLOBE NEWSWIRE) -- Numab Therapeutics AG (“Numab”) announced today the start of a Phase 1 clinical trial evaluating NM32, a next generation tri-specific immuno-oncology therapeutic targeting the receptor tyrosine kinase-like orphan receptor 1 (ROR1) and the T-cell receptor associated antigen CD3. The third binding moiety of NM32 targets serum albumin to provide half-life extension allowing for convenient bi-weekly dosing and to keep the lower molecular weight than immunoglobulin enabling efficient tumor penetration. “Generated from our proprietary Lambda-capTM and MATCHTM technology platform, NM32 represents a T-cell engager designed to help the patient’s immune system recognize and attack tumor cells. ROR1 is overexpressed on a wide spectrum of highly prevalent solid tumor indications but has very limited expression on normal tissue, making it an optimal antigen for a CD3 engager,” said David Urech, Ph.D., Founder and Chief Executive Officer of Numab Therapeutics. “We are pleased to start NM32’s clinical development path enabling us to potentially bring this novel therapy to patients with advanced solid tumors who are in need of treatment options that provide durable anti-tumor activity with a tolerable safety profile. Enrollment is progressing nicely, with patients completing the first treatment cycle of the initial dose level”, commented Martin Stern, Senior Vice President Clinical Science at Numab Therapeutics. “Despite the introduction of checkpoint inhibitors and several commercially available CD3 engagers for the treatment of hematological malignancies, there has been limited success in solid tumors mainly due to the lack of highly tumor-specific antigens allowing selective T-cell activation against tumor cells.” This multi-center Phase 1 study of NM32 is a dose-escalation trial to characterize the pharmacokinetic properties, pharmacodynamic effects and safety profile of NM32 and to select an optimal dosing regimen for further clinical development. It is planned to enroll up to 60 patients with solid tumors overexpressing ROR1 from major clinical sites across the United States. Generated preclinical data in non-human primates indicate a high potency and an excellent safety profile. About NM32 (NM32-2668)NM32 is a next generation tri-specific immuno-oncology drug targeting the receptor tyrosine kinase-like orphan receptor 1 (ROR1) and the T-cell receptor associated antigen CD3. The third domain targets serum albumin to provide half-life extension to allow convenient bi-weekly dosing. T-cell redirection using CD3 engagers is an established treatment modality showing high response rates and durable activity in hematological malignancies and has more recently also shown promising results for selected targets overexpressed in solid tumors. ROR1 is a clinically validated tumor associated antigen with overexpression in several indications with high unmet need including lung, breast, ovarian, endometrial, renal and gastric cancer and limited expression on healthy tissue.

Dupixent significantly reduced itch and hive activity from baseline; 41% of patients achieved well-controlled disease status Confirmatory data to support U.S. regulatory resubmission by year-end; if approved, Dupixent would be the first new targeted treatment for people living with chronic spontaneous urticaria in more than 10 years More than 300,000 people in the U.S. suffer from chronic spontaneous urticaria that is inadequately controlled by antihistamines Oct. 24, 2024 -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Sanofi will present positive data from the Phase 3 LIBERTY-CUPID Study C evaluating the investigational use of Dupixent® (dupilumab) in biologic-naïve patients with uncontrolled chronic spontaneous urticaria (CSU) who receive background therapy with antihistamines. Results showed treatment with Dupixent significantly reduced itch and urticaria activity (itch and hive) scores from baseline, and a higher proportion of patients achieved well-controlled disease status compared to placebo. The data are being shared in a late-breaking oral presentation at the American College of Allergy, Asthma & Immunology (ACAAI) 2024 Annual Scientific Meeting in Boston, Massachusetts. “Chronic spontaneous urticaria is an inflammatory skin condition that affects patients with unpredictable episodes of intense itching and hives, often severely impacting their daily lives," said Thomas B. Casale, M.D., Professor, Internal Medicine, Morsani College of Medicine at the University of South Florida, USA. "These data confirm results seen in the previous Study A and reinforce the potential of Dupixent to significantly alleviate symptoms for patients, helping them to better control this challenging disease.” Study C enrolled 151 children and adults who were randomized to receive Dupixent (n=74) or placebo (n=77) added to standard-of-care histamine-1(H1) antihistamines. At 24 weeks, Dupixent demonstrated significant improvements compared to placebo on: Itch severity score (8.64- vs. 6.10-point reduction from baseline; p=0.02) Urticaria (itch and hive) activity score (15.86- vs. 11.21-point reduction from baseline; p=0.02). Well-controlled disease status (urticaria activity score ≤6; 41% vs. 23%; p=0.005) Complete response (urticaria activity score=0; 30% vs. 18%; p=0.02) The safety results in Study C were generally consistent with the known safety profile of Dupixent in its approved dermatological indications. Overall rates of treatment emergent adverse events (AEs) were 53% for both Dupixent and placebo. AEs more commonly observed with Dupixent (≥5%) compared to placebo included injection site reactions (12% vs. 4%), accidental overdose (7% vs. 3%) and COVID-19 infection (8% vs. 5%). Dupixent has been approved for CSU in Japan and the United Arab Emirates (UAE) and is also under regulatory review in the European Union based on earlier trial readouts. Outside of Japan and the UAE, the safety and efficacy of Dupixent for CSU has not been fully evaluated by any regulatory authority. CSU is a chronic inflammatory skin disease driven in part by type 2 inflammation, which causes sudden and debilitating hives and persistent itch. CSU is typically treated with H1 antihistamines, medicines that target H1 receptors on cells to control symptoms of urticaria. However, the disease remains uncontrolled despite antihistamine treatment in many patients, some of whom are left with limited alternative treatment options. These individuals continue to experience symptoms that can be debilitating and significantly impact their quality of life. More than 300,000 people in the U.S. suffer from CSU that is inadequately controlled by antihistamines. The LIBERTY-CUPID Phase 3 program evaluating Dupixent for CSU consists of Study A, Study B and Study C. Study C was a randomized, double-blind, placebo-controlled clinical trial that evaluated the efficacy and safety of Dupixent as an add-on to standard-of-care antihistamines compared to antihistamines alone in 151 patients aged six years and older with CSU who remained symptomatic despite antihistamine use and were not previously treated with omalizumab (i.e., biologic-naïve). The primary endpoint assessed the change from baseline in itch at 24 weeks (measured by the weekly itch severity score [ISS7], 0-21 scale). Secondary endpoints at 24 weeks, measured by the weekly urticaria activity score (UAS7), included the change from baseline in itch and hives (UAS7, 0-42 scale), proportion of patients achieving well-controlled disease status (UAS7 ≤6), and complete response (UAS7=0). Dupixent, which was invented using Regeneron’s proprietary VelocImmune® technology, is a fully human monoclonal antibody that inhibits the signaling of the IL-4 and IL-13 pathways and is not an immunosuppressant. The Dupixent development program has shown significant clinical benefit and a decrease in type 2 inflammation in Phase 3 trials, establishing that IL-4 and IL-13 are two of the key and central drivers of type 2 inflammation that play a major role in multiple related and often co-morbid diseases. Dupixent has received regulatory approvals in more than 60 countries in one or more indications including certain patients with atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyps, eosinophilic esophagitis, prurigo nodularis, CSU, and chronic obstructive pulmonary disease in different age populations. More than 1,000,000 patients are being treated with Dupixent globally. Regeneron's VelocImmune technology utilizes a proprietary genetically engineered mouse platform endowed with a genetically humanized immune system to produce optimized fully human antibodies. When Regeneron's co-Founder, President and Chief Scientific Officer George D. Yancopoulos was a graduate student with his mentor Frederick W. Alt in 1985, they were the first to envision making such a genetically humanized mouse, and Regeneron has spent decades inventing and developing VelocImmune and related VelociSuite® technologies. Dr. Yancopoulos and his team have used VelocImmune technology to create a substantial proportion of all original, FDA-approved or authorized fully human monoclonal antibodies. This includes REGEN-COV® (casirivimab and imdevimab), Dupixent, Libtayo® (cemiplimab-rwlc), Praluent® (alirocumab), Kevzara® (sarilumab), Evkeeza® (evinacumab-dgnb), Inmazeb® (atoltivimab, maftivimab and odesivimab-ebgn) and Veopoz™ (pozelimab-bbfg). Dupilumab is being jointly developed by Regeneron and Sanofi under a global collaboration agreement. To date, dupilumab has been studied across more than 60 clinical trials involving more than 10,000 patients with various chronic diseases driven in part by type 2 inflammation. In addition to the currently approved indications, Regeneron and Sanofi are studying dupilumab in a broad range of diseases driven by type 2 inflammation or other allergic processes in Phase 3 trials, including chronic pruritus of unknown origin and bullous pemphigoid. These potential uses of dupilumab are currently under clinical investigation, and the safety and efficacy in these conditions have not been fully evaluated by any regulatory authority.

Johnson & Johnson (JNJ) and Eli Lilly (LLY), two pharmaceutical giants, are expected to get new data on their key drugs in the highly competitive dermatology market. Johnson & Johnson evaluated the use of its drug Tremfya in patients with moderate plaque psoriasis involving a specific site of low body surface area that has failed local treatment. In a press release, Johnson & Johnson explained that "special sites" refer to those sensitive or highly visible areas affected by psoriasis, such as the scalp, face, skin folds, and genitals. According to Johnson & Johnson, the SPECTREM study is the first large-scale trial to measure skin clearance and other outcomes in a patient group. The drugmaker found that 74.2% of patients treated with Tremfya met the primary endpoint by achieving disease clearance or minimal disease. In contrast, only 12.4 percent of patients in the placebo group achieved the same level of response. Tremfya also proved beneficial in secondary endpoints and patient-reported measures of quality of life, Johnson & Johnson said. According to the company, although psoriasis has a significant impact on patients' daily lives, the patient population is largely underserved by systemic treatment. Tremfya is positioned as a strong successor as competition for biosimilars heats up and the impact of the Inflation Reduction Act on drugmakers' immunity star Stelara looms. The biologic recently gained recognition in ulcerative colitis, competing with AbbVie's Humira successor Skyrizi. Meanwhile, Eli Lilly tested its IL-13 inhibitor Ebglyss in patients with moderate to severe atopic dermatitis who had previously been treated with Regeneron and Sanofi's immune giant Dupixent (dupilumab). The Phase 3b ADapt study found that 57 percent of patients with Eli Lilly's drug had a 75 percent or greater improvement in their eczema Area and Severity Index (EASI-75) score at week 16. The study measured the extent and severity of skin disorders. By week 24, 60 percent of patients treated with ebglyss experienced this level of improvement. Lilly said in a press release that the results were generally consistent with previous studies of the drug in patients who had not used Dupixent. By week 16, 46 percent of Ebglyss patients with an inadequate response to Dupixent met EASI-75 criteria. Mark Genovese, M.D., senior vice president of Eli Lilly's immunization division, said in a company release: "This trial supports a growing body of data suggesting that healthcare providers can be confident in using Ebglyss as a first-line biologic therapy for moderate to severe atopic dermatitis, and highlights that Ebglyss offers meaningful benefit to individuals who have already tried other biologic therapies, such as dupilumab, and may have a more difficult-to-treat disease." Ebyglyss received its first FDA approval for atopic dermatitis last month, following European approval in 2023. It is the third biologics Lilly has developed in its growing immunology segment and will compete with dominant DuPont in a crowded market.
