Anti-thymic stromal lymphopoietin monoclonal antibody in patients with chronic rhinosinusitis with nasal polyps (DUBHE): Rationale and design of a multicenter, randomized, double-blind, placebo-controlled study

Article

Author: Yan, Bing ; Xian, Mu ; Zhang, Luo ; Lan, Feng ; Shen, Shen ; Wang, Chengshuo

Background::

Chronic rhinosinusitis with nasal polyps (CRSwNP) has a complex pathogenesis and is difficult to treat, which brings a huge economic burden to society. Despite all the progress in the treatment of CRSwNP, some patients with CRSwNP still experience recurrence. Therefore, there is an urgent need to develop novel drugs and treatments for CRSwNP. Thymic stromal lymphopoietin (TSLP) is produced by epithelial cells and mediates type 2 and nontype 2 inflammation through various downstream cellular immune and inflammatory pathways. Anti-TSLP treatment with tezepelumab has been proven to be effective in treating patients with uncontrolled asthma, regardless of their peripheral blood eosinophil levels being low or high. However, there is no relevant research on the usage of anti-TSLP monoclonal antibodies for the treatment of uncontrolled CRSwNP.

Objective::

This is the first phase Ib/IIa study for subjects with uncontrolled CRSwNP, aiming to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity, and preliminary efficacy of multiple ascending doses (MAD) of anti-TSLP monoclonal antibody.

Methods::

The DUBHE is a multicenter, randomized, double-blind, placebo-controlled, phase Ib/IIa clinical study. The study will be composed of 3 periods: a screening/run-in period of 4 weeks, a treatment period of 52 weeks (16 weeks of double-blind treatment period +36 weeks of open-label treatment period), and a safety follow-up period of 12 weeks. No more than 113 subjects with uncontrolled CRSwNP will be divided into 4 groups to receive different doses of CM326 or placebo treatments (55 mg every two weeks [Q2W] group, 110 mg Q2W group, 220 mg Q2W group, and 220 mg every four weeks [Q4W] group). Enrolled patients will be stratified by tissue eosinophil count (TEC).

Results::

The safety of the monoclonal antibody that targets TSLP in uncontrolled CRSwNP and its preliminary efficacy at 16 weeks of treatment.

Conclusion::

In this study, for the first time, the safety and preliminary efficacy of MAD of CM326 will be verified. The efficacy of CM326 in patients with eosinophilic CRSwNP (TEC ≥55/ high power field [HPF]), as well as noneosinophilic CRSwNP (TEC <55/HPF) will be testified.

Trial registration::

NCT05324137.

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.

Among the 7 patients, 100.0% (7/7) achieved a platelet count ≥50 × 109/L within 8 weeks after administration with the first dose, with a median time to response of 1 week (range from 1 to 3). CM326 (TSLP antibody) Continuously proceeded with a Phase II clinical study to evaluate the efficacy and safety of CM326 in adult patients with moderate-to-severe AD. Continuously proceeded with a Phase Ib/IIa clinical trial to evaluate the safety, tolerability, pharmacokinetics/pharmacodynamics, immunogenicity, and preliminary efficacy of CM326 in subjects with CRSwNP. Our partner, CSPC, has initiated the Phase II clinical study for the treatment of moderate-to-severe asthma. Progress of other pipeline products: CM355/ICP-B02 (CD20xCD3 bispecific antibody) Continuously proceeded with a Phase I/II clinical trial to assess the safety, tolerability, PK, and the preliminary anti-tumor activity of CM355 in relapsed or refractory non-Hodgkin's lymphoma (r/r NHL). As of the date of this announcement, all the 13 patients who were treated CM355 at dose ≥6mg achieved response with the ORR of 100%. CM336 (BCMAxCD3 bispecific antibody) Continuously proceeded with a Phase I/II clinical study in 2023 to assess the safety, tolerability, pharmacokinetics, and the anti-tumor activity of CM336 in RRMM. CM350 (GPC3xCD3 bispecific antibody) Continuously proceeded with a Phase I/II clinical study in 2023 to assess the safety, tolerability, pharmacokinetics, and the preliminary efficacy of CM350 in patients with advanced solid tumors. CM338 (MASP-2 antibody) Continuously proceeded with a Phase II clinical study in 2023 to evaluate the efficacy and safety of CM338 injection in subjects with immunoglobulin A nephropathy (IgAN). CM369/ICP-B05 (CCR8 antibody) Continuously proceeded with a Phase I trial to evaluate the safety, tolerability, pharmacokinetic characteristics, and efficacy of CM369 in subjects with advanced solid tumors and relapsed or refractory NHL. We will explore the combination of CM369 with other immunotherapies in various cancer indications after collecting the safety data of monotherapy. CM383 (Aβ protofibrils antibody) Submitted an IND application for CM383 in February 2024, and we are about to conduct a Phase I clinical study of the safety, tolerability, pharmacokinetics, pharmacodynamics and immunogenicity of single dose-escalation administration in healthy subjects.
