Abstract

Background

Florensocatib (formerly known as HSK31858) is a novel reversible inhibitor of dipeptidyl peptidase 1. We sought to determine the efficacy and safety of florensocatib in decreasing exacerbation frequency in Chinese adults with bronchiectasis.

Methods

The HOPE-BE trial was a phase 3, randomised, placebo-controlled trial which determines the efficacy and safety of high-dose florensocatib (40 mg once daily) versus placebo in Chinese adults with bronchiectasis who had two or more exacerbations within the past year. Patients were randomly assigned in a 2:1 ratio to receive florensocatib 40 mg or matching placebo once daily for 52 weeks. We recorded demographics, medical history, bacterial infection status and quality-of-life and performed spirometry at baseline.

Results

We randomised 700 patients who were enrolled from 67 sites in mainland China between September 2024 and November 2025. 60.4% of patients were female. 559 (79.9%) and 141 (20.1%) of patients, respectively, had two and three or more exacerbations in the past year. The median (interquartile range) of 24-h sputum weight was 14.8 (29.3) g, and the median (interquartile range) of sputum purulence score was 5.0 (2.0). 192 (27.4%) patients were culture positive to Pseudomonas aeruginosa, and demonstrated significantly higher 24-h sputum volume and purulence score, and lower lung function and quality-of-life scores. Significant geographical variations were seen regarding comorbidity, blood eosinophil counts and sputum bacteriology.

Conclusion

The baseline demographic characteristics of the HOPE-BE trial may provide important clues to future therapeutic efficacy assessment in adults with bronchiectasis.

Introduction

Bronchiectasis is a common chronic respiratory disease in which neutrophilic inflammation is responsible for chronic sputum production and frequent exacerbations [1–3]. Clinical practice guidelines have highlighted the paucity of licensed therapy [4–7]. Although low-dose macrolides significantly decrease symptom burden and exacerbation risks [8], long-term administration increased the risks of resistance and diminished therapeutic responses [9, 10]. The guidelines have addressed the unmet needs in developing new drugs to halt disease progression via mitigating airway inflammation [4–7].

Despite the heterogeneity in clinical manifestations, activated neutrophils may release neutrophil serine proteases (NSPs) such as neutrophil elastase, cathepsin G and proteinase 3 [11, 12]. Bronchiectasis patients with higher levels of sputum matrix metalloproteinase and neutrophil elastase exhibited significantly elevated risk of exacerbations [3, 13]. The activated inflammasome within airway epithelium and neutrophils potently induced neutrophil extracellular traps formation that damage airways [14]. Hence, targeted therapies might translate into clinical benefits.

Dipeptidyl peptidase-1 (DPP-1, cathepsin C) is the upstream switch controlling NSP synthesis within neutrophils. Interventions that inhibit DPP-1 may maintain neutrophil effector functions while minimising NSP release [11, 15, 16]. Several small molecules could effectively suppress DPP-1 activity. Brensocatib significantly decreased exacerbation frequency, prolonged the time to the first exacerbation and markedly decreased sputum NSP concentrations in the WILLOW [17] and ASPEN trial [18], while BI 1291583 demonstrated a significant dose–response benefit and nominally lowered the exacerbation risk in the AIRLEAF trial [19]. Both drugs were well tolerated.

Expanding the list of DPP-1 inhibitors may consolidate the evidence of targeted therapies of neutrophilic inflammation and improve drug accessibility globally. Florensocatib (HSK31858) is a novel oral reversible DPP-1 inhibitor with high potency in inhibiting NSP activity in vitro. Following safety assessment in two phase 1 trials [20], the SAVE-BE trial demonstrated a 60% reduction in exacerbation risk, markedly decreased daily sputum weight and a high safety profile among Chinese adults with bronchiectasis [21].

We conducted the phase 3 trial of florensocatib among Chinese adults with bronchiectasis (ClinicalTrials.gov registry: NCT06660992). The primary goal is to assess the effects of florensocatib in decreasing the annualised exacerbation frequency of bronchiectasis over 52 weeks. Secondary objectives included the assessment of florensocatib in prolonging the time to the first exacerbation, decreasing sputum volume and purulence, improving lung function and quality-of-life, etc.

Here, we report the design of the HOPE-BE trial and outline baseline demographic characteristics.

Methods

Study design and end-points

HOPE-BE is a phase 3, randomised, placebo-controlled trial which determined the efficacy and safety of high-dose florensocatib (40 mg once daily) versus placebo in Chinese adults. Eligible participants were randomly assigned 2:1 to receive florensocatib 40 mg (treatment group) or matching placebo (placebo group) once daily for 52 weeks, followed up for safety for 4 weeks thereafter. Study visits occurred at baseline, day 1 and weeks 4, 16, 28, 40 and 52 and at four sessions via telephone (weeks 10, 22, 34 and 46).

The primary efficacy end-point was the annualised frequency of exacerbation within 52 weeks compared with placebo. We defined an acute exacerbation based on the EMBARC expert consensus as the new onset or deterioration of three or more symptoms lasting for >48 h that resulted in antibiotic treatment [22]. Severe exacerbations denoted those requiring hospitalisation.

Secondary efficacy end-points consisted of the time to the first exacerbation, the proportion of patients without exacerbation within 52 weeks, the change from baseline in forced expiratory volume in 1 s (FEV1) at 52 weeks, change from baseline in 24-h sputum weight at 52 weeks, change from baseline in sputum purulence score at 52 weeks, and the change from baseline to week 52 in the Respiratory Symptoms Scale of the Quality of Life Questionnaire for Bronchiectasis (QoL-B-RSS) [23]. The exploratory end-point was the change from baseline in the Bronchiectasis Health Questionnaire (BHQ) score at 52 weeks [24].

Study participants

Key inclusion criteria

We enrolled adult outpatients from 67 sites in mainland China between September 2024 and November 2025 (supplementary table S1). Eligible patients were aged ≥18 years, had a body mass index of ≥18.0 kg·m−2, had a clinical diagnosis of bronchiectasis affecting one or more lung lobes based on chest computed tomography (bronchial dilatation and compatible respiratory symptoms), and had two or more documented exacerbations within the 12 months before screening.

The trial was conducted by following the Declaration of Helsinki and the Good Clinical Practice. The trial protocol has been approved by The First Affiliated Hospital of Guangzhou Medical University and each participating site.

Core exclusion criteria

Core exclusion criteria included a primary diagnosis of COPD or asthma, cystic fibrosis, destroyed lungs, and active mycobacterial or fungal disease necessitating active treatments. Other important exclusion criteria were severe systemic diseases (e.g. uncontrolled hypertension or diabetes, recent stroke), active hepatitis, malignancy within last 5 years, exacerbation within last 4 weeks, antibiotic use (except for low-dose macrolides) within last 4 weeks, pregnancy or lactation. See the supplementary appendix for details.

Randomisation and masking

We randomly assigned eligible patients who had completed the 4-week screening via a central interactive Web-response system. Because in the phase 2 SAVE-BE trial, the 40 mg doses yielded a greater reduction than the 20 mg doses in exacerbation frequency (60% versus 48% reduction) and a similar safety profile [21], the investigators had reached consensus with the National Medical Products Administration that only the 40 mg doses be retained. Randomisation was stratified by the exacerbation frequency within the previous year (<3 versus ≥3 annually). The sequence of allocation was concealed by the electronic case report form system. Both study investigators and participants were masked.

Study procedures

Assessments at screening consisted of the documentation of demographics, medical history and exacerbations, previous and concomitant medications. Participants were requested to complete a chest computed tomography (waved if the participant had undergone one within 12 months at the same site). All chest radiographs were transferred to the leading site, where two senior independent radiologists who remained blinded throughout the trial provided central review. Spontaneous sputum was collected at screening, throughout treatment visits and at follow-up visits, and could be aided by chest physiotherapy – postural drainage and active cycle of breathing. However, induction was allowed when spontaneous sputum could not be provided despite multiple attempts. Fresh sputum was sent to the microbiology laboratory for conventional culture. Spirometry was performed with the core metrics of forced vital capacity, FEV1 and maximal mid-expiratory flow. Patients at baseline completed the QoL-B-RSS (to calculate the QoL-B-RSS, range: 0–100, with higher scores indicating better quality of life) [23] and the BHQ (to calculate the total score, range: 0–100, with higher scores indicating better quality of life) [24].

Participants collected 24-h sputum in the designated transparent sterile plastic pots, submitted the next day following screening to determine baseline daily sputum weight and purulence. All 24-h sputum pots were weighted on an electronic balance. Sputum purulence was rated based on the standardised colour chart.

Adherence and adverse events recording

Adherence was defined as the percentage of the number of study drugs consumed over the entire number of study drugs dispensed during treatment. We rated adherence as good if participants had administered 80% to 120% of the intended quantity of florensocatib or placebo (tablet counting conducted upon follow-up).

We evaluated safety profiles throughout week 52 by documenting the adverse events (AEs), conducting physical examinations, laboratory testing and 12-lead electrocardiography. Investigators documented the AEs via meticulous questions, physical examination and diary card inspection.

Sample size estimation

Based on the WILLOW and SAVE-BE trial [17, 21], we assumed an annualised exacerbation rate of 1.37 events per patient-year in the placebo group and 0.87 events per patient-year in the florensocatib group, based on the negative binomial dispersion settings. We fitted a negative binomial distribution model by using the exacerbation frequency data from the SAVE-BE trial [21], where the estimated dispersion parameter was 1.27 (95% confidence interval (95% CI) 0.81–1.99). We estimated the enrolment of 446 patients in the florensocatib group and 223 in the placebo group (totaling 669 patients) with a one-sided significance level of 0.025, a power of 90%, a negative-binomial dispersion parameter of 1.40 and a 20% dropout rate.

Statistical analysis

The full analysis set (FAS) was the principal analysis set, while the per-protocol set (PPS) was the supportive set. For the primary end-point, we adopted the negative binomial model, with the incidence rate ratio and the corresponding 95% CI being demonstrated, to analyse the annualised exacerbation frequency up to 52 weeks. This model assumed that for participants who discontinued prematurely, the annualised exacerbation rate from discontinuation to Week 52 would be identical to the rate observed from randomisation to discontinuation. To assess the impact of deviation from this assumption, sensitivity analysis was performed under a missing-not-at-random framework. The number of exacerbations occurring between premature discontinuation and week 52 was multiply inputed by using Copy Reference and Tipping-Points Analysis. We compared the two groups by using the Andersen–Gill intensity model. In the PPS, the same negative binomial model was employed as in the primary analysis. All intercurrent events were handled with the while-on-treatment strategy, analysed identically to the primary analysis. Concomitant use of other drugs sharing the same therapeutic target was addressed with the treatment policy strategy, while all other aspects remain unchanged and were analysed as in the primary analysis. Deaths from any cause was consistently handled with the composite strategy, with all other aspects unchanged and analysed using the same approach as the primary analysis.

For secondary end-points, the time to the first exacerbation was summarised with Kaplan–Meier curves; the two groups were compared with the log-rank test and by restricted mean survival time model. A Cox regression model was used to estimate the hazard ratio for the time to the first exacerbation. The proportion of patients who remained free of exacerbations was compared with a logistic regression model that included the number of exacerbations in the previous 12 months (<3 versus ≥3) as covariate. Changes from baseline in FEV1, 24-h sputum weight, sputum purulence score and QoL-B-RSS at Week 52 were analysed with the mixed model for repeated measures (MMRM). This included the baseline value of the secondary end-point and the number of exacerbations in the previous year (<3 versus ≥3) as the covariate, and treatment group, visit and the treatment-by-visit interaction as fixed effects. Least-squares mean differences between two groups and 95% CIs were calculated.

Subgroup analyses of the primary end-point was performed in the FAS according to the baseline: 1) Pseudomonas aeruginosa infection (present versus absent); and 2) long-term macrolides therapy (yes versus no). The same method used in the primary analysis of the primary end-point was applied.

The Safety Set served as the safety analysis population. Safety data were summarised according to the treatment actually received and evaluated regarding the incidence and severity of AEs. All AEs were coded using MedDRA version 27.0 or higher and graded according to CTCAE version 5.0. The incidence of treatment-emergent adverse events were summarised by System Organ Class and Preferred Term, and further classified within each category by the type of suspected relationship to the study drug and by severity.

For pharmacokinetic analysis, blood concentrations collected at the scheduled sampling visits were summarised descriptively for all dosed individuals. For exploratory analysis, the change in BHQ score from baseline to Week 52 was analysed using the MMRM.

All analyses were presented with two-sided p-values at a significance threshold of 0.05. We did not input any missing data. We applied no hierarchical order for evaluating secondary end-points and no adjustment for multiplicity.

Results

Patients

Of 885 patients who underwent screening, 702 underwent randomisation. Two patients failed to produce sufficient spontaneous sputum for bacterial culture and were not included in the FAS. Therefore, 700 patients were retained in the FAS. Figure 1 demonstrates the study design and the main inclusion/exclusion criteria.

63 (9.0%) patients had coexisting asthma and 219 (31.3%) had coexisting COPD. When stratified by geographical region, the proportions of respiratory diseases were highest in central China and lowest in south China (figure 2). When analysing other systemic diseases, metabolic disorders ranked first (n=285, 40.7%), followed by gastrointestinal disorders (n=250, 35.7%) and cardiovascular disorders (n=211, 30.1%). The use of concomitant medications varied considerably across different regions, particularly for mucoactive drugs and inhaled bronchodilators (figure 3).

Regarding concomitant use of medications, the most common type was long-acting bronchodilators (∼15%), followed by mucoactive drugs (11.9%). 8.3% of patients reported the use of inhaled corticosteroids, and low-dose macrolides was used in 2.0% of patients only.

Functional and laboratory testing

The mean±sd pre-bronchodilator FEV1 was 69.6±24.3% predicted. 38.9% of patients had an FEV1 of 80% predicted or higher, and this was 35.1% for FEV1 between 50% and 80% predicted, and 21.7% for FEV1 between 35% and 49% predicted. 68 (9.7%) patients had a blood eosinophil count of ≥300 cells·μL−1, with minor geographic differences in the proportion of patients with blood eosinophilia (figure 4). P. aeruginosa was isolated from 192 (27.4%) patients (table 2).

Patient characteristics stratified by P. aeruginosa isolation

Patients isolated with P. aeruginosa demonstrated a significantly higher 24-h sputum volume (median: 23.6 versus 12.1 g) and sputum purulence score (median: 6 versus 4) than those without. The proportion of patients who had three or more exacerbations within the previous year was markedly higher in patients with isolation of P. aeruginosa than those without (26.0% versus 18.0%). Both the QoL-B-RSS (mean: 60.6 versus 68.0 points, p<0.05) and FEV1 (mean: 61.3% versus 72.8%, p<0.05) was significantly lower in patients with P. aeruginosa isolation than those without. However, the percentage of patients with blood eosinophilia did not differ significantly, nor did the concomitant use of inhaled corticosteroids or low-dose macrolides (figure 5a). Patients residing in south China yielded the highest rate of P. aeruginosa positive culture (37.9%), followed by patients living in north China (32.1%). By contrast, the lowest rate of P. aeruginosa isolation was identified among patients residing in east China (23.5%) (figure 5b).

Discussion

The study design and baseline demographic characteristics for the HOPE-BE trial are reported here. Our findings for patient demographic characteristics echoed those in the SAVE-BE trial [21] regarding the mean age (56 versus 56 years), percentage of female patients (60% versus 61%) and never-smokers (85% versus 86%), percentage of patients with coexisting asthma (9% versus 8.5%) and COPD (31% versus 26%), and percentage of patients with three or more exacerbations in the past year (20% versus 21%). Compared with the AIRLEAF [19], WILLOW [17] and ASPEN trials [18], our cohort was younger and had a higher proportion of never-smokers and fewer annual exacerbations.

Two important treatable traits, the 24-h sputum weight and sputum purulence score, cannot be compared because they were not reported in three other trials [17–19]. As with the SAVE-BE trial [21], the therapeutic effects of florensocatib in improving respiratory symptoms in terms of decreasing 24-h sputum weight and sputum purulence score will be explored with a larger sample size in the HOPE-BE trial.

Sputum bacteriology is an important determinant of the clinical outcomes of bronchiectasis, and the primary end-point and key secondary end-points will be analysed by stratifying the isolation status of P. aeruginosa in the HOPE-BE trial. In the next stage of data analysis, comparison of the disease severity will be possible following the incorporation of the BSI metric when the trial is formally completed.

The HOPE-BE trial adopted the higher dose group of florensocatib only. Because of the reasons mentioned in the Methods, the principal investigators concurred with the National Medical Products Administration that patients should be randomised in a 2:1 ratio to maximise the probability of receiving the optimal treatment.

The HOPE-BE trial also determined the efficacy of florensocatib in decreasing the 24-h sputum weight and sputum purulence score, because the aggravated neutrophilic inflammation elicited mucus hypersecretion. Decreased daily sputum weight was indicative of mitigated airway inflammation and improved quality of life. Our findings would provide further evidence on top of the clinical trial of florensocatib in adults with airway mucus hypersecretion (Clinicaltrials.gov registry: NCT06820749).

Our study is limited by the demonstration of baseline characteristics. Currently, acquisition of chest computed tomographic images is ongoing, and rating of the modified Reiff score by two independent senior radiologists and calculation of the Bronchiectasis Severity Index, along with other important information such as the underlying etiology and the CONSORT diagram (because our study has not been unblinded), will be reported in a future publication. Furthermore, there existed some differences in patient characteristics such as concomitant use of low-dose macrolides or inhaled antibiotics (patients have rarely received regular treatments prior to inclusion in our trial). Future studies will continue to explore, with a number of simple clinical metrics, the bedside tools to predict the efficacy of florensocatib.

The marketing approval of brensocatib has signalled the triumph of targeted anti-inflammatory drugs for bronchiectasis. The HOPE-BE trial is the largest randomised controlled trial of a DPP-1 inhibitor in the Chinese population. It could help to decipher the possible differences in therapeutic response to different DPP-1 inhibitors across different study populations. Full trial results will be published in future publications.
