RATIONALE:

Rademikibart (formerly CBP-201) is an IL-4Rα-targeting antibody.

OBJECTIVES:

To evaluate rademikibart in adults with moderate-to-severe, persistent, uncontrolled asthma.

METHODS:

In this global phase 2b trial (NCT04773678), 322 patients were randomized 1:1:1 to two rademikibart groups (150 mg or 300 mg every other week, following a 600 mg loading dose) or placebo, administered subcutaneously, for 24 weeks.

MEASUREMENTS AND MAIN RESULTS:

Prebronchodilator (trough) forced expiratory volume in the first second of expiration (FEV₁) at Week 12 (primary endpoint) improved with rademikibart 150 mg and 300 mg: least squares mean changes (95% CI), above placebo, were +140 mL (+44-236 mL; p=0.005) and +189 mL (+92-286 mL; p<0.001), respectively. Prebronchodilator trough FEV₁ improvements occurred rapidly during Week 1, were sustained through Week 24, and greatest in patients with high baseline blood eosinophils (patients with ≥300 eosinophils/mL experienced placebo-adjusted FEV₁ improvement at Week 24 of +420 mL [95% CI, +239-600 mL] in the 300 mg group). Rapid and sustained statistically significant improvements were also observed in percent predicted FEV₁ and Asthma Control Questionnaire score across 24 weeks. Through Week 24, proportions of patients with ≥1 exacerbation were 7.5% (150 mg) and 9.3% (300 mg) vs 16.7% (placebo). 88% of patients completed treatment. Treatment-emergent adverse events (TEAEs) were generally similar to placebo, and no eosinophilia was observed. Injection site reactions were mostly mild. The most common TEAEs (10-12% of patients) were cough, COVID-19, and dyspnea.

CONCLUSIONS:

Rapid and sustained improvements in lung function and asthma control were gained across 24 weeks of rademikibart therapy.

Emerging drugs for the treatment of atopic dermatitis: a focus on phase 2 and phase 3 trials

Review

Author: Su, Malcolm ; Obed, Ogechi ; Chong, Albert C ; Ong, Peck Y

INTRODUCTION:

Atopic dermatitis (AD) is an inflammatory skin condition that affects millions of pediatric and adult patients with well-studied impact on morbidity and quality of life. Management occurs in a stepwise fashion beginning with preventative measures before immunomodulators are introduced. However, challenges remain in treatment of moderate-to-severe atopic dermatitis that is refractory to first- and second-line treatments and there are only few topical anti-inflammatory options, especially for pediatric patients.

AREAS COVERED:

New medications are required to address these gaps as lesions may persist despite treatment or patients may discontinue treatment due to actual or anticipated adverse effects of mainstay medications. Emerging research into the pathophysiology of AD and the immune system at large has provided opportunities for novel interventions aimed at stopping AD mechanisms at new checkpoints. Clinical trials for 36 agents currently in phase 2 or phase 3 are evaluated with particular focus on the studies for, B244, CBP-201, tapinarof, lebrikizumab, nemolizumab, amlitelimab, and rocatinlimab as they explore novel pathways and have some of the most promising results.

EXPERT OPINION:

These clinical trials contribute to the evolution of AD treatment toward greater precision based on salient pathways with a particular focus on moderate-to-severe AD to enhance efficacy and minimize adverse effects.

Efficacy and safety of rademikibart (CBP-201), a next-generation mAb targeting IL-4Rα, in adults with moderate to severe atopic dermatitis: A phase 2 randomized trial (CBP-201-WW001)

Article

BACKGROUND:

Rademikibart (CBP-201) is a next-generation IL-4 receptor alpha-targeting antibody.

OBJECTIVE:

We sought to evaluate rademikibart in adults with moderate to severe atopic dermatitis.

METHODS:

A total of 226 patients were randomized, double-blind, to subcutaneous rademikibart (300 mg every 2 weeks [Q2W], 150 mg Q2W, 300 mg every 4 weeks [Q4W]; plus 600-mg loading dose) or placebo. Randomization began in July 2020. The trial was completed in October 2021.

RESULTS:

The WW001 phase 2 trial achieved its primary end point: significant percent reduction from baseline in least-squares mean Eczema Area Severity Index (EASI) to week 16 with rademikibart 300 mg Q2W (-63.0%; P = .0007), 150 mg Q2W (-57.6%; P = .0067), 300 mg Q4W (-63.5%; P = .0004) versus placebo (-39.7%). EASI scores decreased significantly with 300 mg Q2W and Q4W at the earliest assessment (week 2), with no evidence of plateauing by week 16. Significant improvements were also observed in secondary end points, including pruritus. Across the primary and secondary end points, efficacy tended to be comparable with 300 mg Q2W and Q4W dosing. Rademikibart and placebo had similar, low incidence of treatment-emergent adverse events (TEAEs) (48% vs 54%), serious TEAEs (1.8% vs 3.6%), TEAEs leading to treatment discontinuation (1.2% vs 1.8%), conjunctivitis of unspecified cause (2.9% vs 0%), herpes (0.6% vs 1.8%), and injection-site reactions (1.8% vs 1.8%). Although no discontinuations were attributed to coronavirus disease 2019, pandemic-related restrictions likely had an impact on trial conduct.

CONCLUSIONS:

Rademikibart was efficacious and well tolerated at Q2W and Q4W intervals. Q4W dosing is a more convenient frequency than approved for current therapies.

Connect Biopharma Announces Positive Type C Meeting with the FDA for Rademikibart

– FDA aligned on plan to initiate parallel Phase 2 trials of rademikibart in patients with moderate-to-severe asthma or COPD experiencing an acute exacerbation – – Expect to initiate both trials in Q2 2025 – SAN DIEGO, April 01, 2025 (GLOBE NEWSWIRE) -- Connect Biopharma Holdings Limited (Nasdaq: CNTB) (Connect or Connect Biopharma), a clinical-stage biopharmaceutical company focused on transforming acute and chronic care of asthma and chronic obstructive pulmonary disease (COPD), today announced positive feedback from its Type C meeting with the U.S. Food and Drug Administration (FDA), Division of Pulmonology, Allergy, and Critical Care, in the Office of Immunology and Inflammation. “We are pleased to have the FDA’s alignment on our two parallel Phase 2 trials evaluating rademikibart in patients experiencing an acute exacerbation of asthma or COPD, an area where no biologic therapies have been approved or systematically studied,” said Barry Quart, Pharm.D., CEO and Director of Connect Biopharma. “During our Type C meeting, the FDA acknowledged the unmet need for reducing recurrent exacerbations during the vulnerable 28-day period following an acute exacerbation of asthma or COPD. In our previously completed Phase 2 study for the maintenance treatment of asthma, a 600 mg subcutaneous (SC) loading dose of rademikibart was well-tolerated and delivered robust improvement in pulmonary function in less than 24 hours. This promising data suggests that rademikibart could provide meaningful and rapid benefit to the millions of patients who experience exacerbations of asthma or COPD and are seen in emergency departments or are hospitalized each year.” Based on the advice from the FDA at the meeting, Connect plans to begin enrolling patients in these trials during the second quarter of this year. The two parallel Phase 2 randomized, double-blind, placebo-controlled trials are expected to each enroll approximately 160 patients and include patients with uncontrolled, moderate-to-severe asthma or COPD with eosinophils ≥300 cells/µL who are experiencing an acute exacerbation. The trials are designed to evaluate the benefits of a single 600 mg SC dose of rademikibart in patients over 28 days following an acute exacerbation. Based on the results of a recently published trial of a similar design, approximately 45% of patients receiving the current standard of care experienced treatment failure in the 28 days following an acute exacerbation, demonstrating the continued unmet need for better treatments for these patients1. Connect expects to report data from both rademikibart Phase 2 trials in the first half of 2026 with a cash runway into 2027. “Asthma and COPD patients face a heightened risk of further exacerbations within the first 28 days following an initial episode. While biologics have demonstrated significant success in maintenance therapy, none have been approved to address airway symptoms immediately after an acute exacerbation,” said Mario Castro, MD, MPH, Professor and Chief of Pulmonary, Critical Care and Sleep Medicine at the University of Kansas School of Medicine. “The pulmonology community is encouraged by the plan to evaluate the potential benefits of a single 600 mg SC dose of rademikibart following an acute exacerbation in these Phase 2 trials in patients with asthma and COPD.” About Connect Biopharma and Rademikibart Connect Biopharma is a clinical-stage biopharmaceutical company dedicated to transforming care for asthma and COPD. Headquartered in San Diego, California, the company is advancing rademikibart, a next-generation, potentially best-in-class anti-interleukin-4-receptor alpha (IL-4Rα) antibody. With an initial focus on acute exacerbations—an area with significant unmet need—rademikibart has the potential to also drive chronic utilization in asthma and COPD amongst the approximately 1 million asthma patients and 1.3 million COPD patients in the U.S. who experience acute exacerbations annually. In a Phase 2 trial for asthma, rademikibart demonstrated strong efficacy and safety data, with clinically meaningful reductions in exacerbations and rapid, statistically significant improvements in FEV1, observed within one week—and in most cases, within 24 hours via home spirometry.

Severe Asthma Overview Severe asthma is a chronic respiratory condition characterized by persistent symptoms that are difficult to control, even with high-dose medications. Unlike milder forms of asthma, severe asthma can significantly impair the quality of life and may result in frequent exacerbations requiring hospitalization. The exact cause of severe asthma is not entirely clear, but it often arises from a combination of genetic and environmental factors. These may include respiratory infections, allergens (pollen, mold, dust mites), pollutants (tobacco smoke, air pollution), occupational irritants, and lifestyle factors such as obesity and stress. Severe asthma can also develop in people whose milder asthma is not well-controlled over time. Diagnosis of severe asthma begins with a comprehensive medical history, physical examination, and pulmonary function tests like spirometry to assess lung function. Doctors may also order additional tests, such as chest X-rays, blood tests, and allergy tests to identify triggers. A key factor in diagnosing severe asthma is the persistence of symptoms despite the optimal use of standard asthma treatments. Managing severe asthma typically requires a multifaceted approach. Inhaled corticosteroids and long-acting bronchodilators are the mainstays of treatment. For those who do not respond to these medications, biologic therapies (such as omalizumab, mepolizumab, or dupilumab) may be prescribed to target specific pathways involved in the inflammatory response. In addition, patients with severe asthma may benefit from lifestyle modifications, including weight management, avoiding triggers, and pulmonary rehabilitation. In extreme cases, systemic corticosteroids may be necessary, although long-term use can have serious side effects.
