[0002] ANTI-IL-5 ANTIBODY IN THE TREATMENT OF CHRONIC RHINOSINUSITIS WITH

[0003] NASAL POLYPS

[0004] FIELD OF THE INVENTION

[0005] The present invention relates to antigen binding proteins, e.g. an antibody, which bind to IL-5, for use in the treatment of chronic rhinosinusitis with nasal polyps, wherein the nasal polyps score and / or nasal obstruction score is reduced.

[0006] BACKGROUND TO THE INVENTION

[0007] Prolonged stimulation from chronic inflammation of the nasal / paranasal mucosa in chronic rhinosinusitis with nasal polyps (CRSwNP) can lead to tissue damage and aberrant tissue repair causing significant recurring symptoms and the growth of nasal polyps (NP) (Bachert et al., 2021; Gevaert et al., 2022; Shah et al., 2023).

[0008] Current standard of care (SoC) for CRSwNP involves maintenance intranasal corticosteroids (INCS; except Japan) and intranasal nasal douching with saline. Shortterm systemic CS (SCS) with / without antibiotics are used to manage flare-ups while endoscopic sinus surgery is an option to remove persistent polyps (Fokkens et al., 2023; Hellings et al., 2024; Shah et al., 2016). Short-term oral CS temporarily improve symptoms though repeat use can cause adverse events (AEs) (Bachert et al., 202). Surgical removal of nasal polyps also improves symptoms but may be associated with complications. Nasal polyp recurrence can be frequent, particularly in patients with an eosinophilic phenotype, as nasal polyp surgery does not address the underlying chronic inflammation (Bachert et al., 2021)

[0009] Patients with CRSwNP experience persistent symptoms, predominantly driven by type 2 inflammation in up to 85% of cases (Bachert et al., 2021; Gevaert et al., 2022); though this percentage varies by country, with a mixture of endotypes predominating in Asia (Wang et al., 2016). Type 2 inflammation is driven by Th2 cells and ILC2 cells, which produce type 2 cytokines such as interleukin (I L)-5, IL-4 and IL-13 (Maspero et al., 2022). High concentrations of these cytokines are present in NP tissue (Bachert et al., 2024); for IL-5, this is associated with increased disease severity (Gevaert et al., 2022). IL-5 stimulates eosinophil production and, in concert with IL-4 and IL-13, promotes eosinophil trafficking (Bachert et al., 2024). Collectively, they drive eosinophilic inflammation and orchestrate effects on a wide range of other immune and structural cells (Bachert et al., 2024). 70542W001

[0010] Biologies that target type 2 cytokines may help mitigate the impact of CRSwNP from chronic type 2 inflammation by rebalancing immune responses, impacting NP formation, and restoring epithelial integrity (Gevaert et al., 2022; Bergantini et al., 2023; Buchheit et al., 2021). The biologies mepolizumab (anti-IL-5), dupilumab (anti-IL-4R) and omalizumab (anti-lgE) have been approved as add-on therapy for the treatment of adults with severe uncontrolled CRSwNP, having demonstrated clinical benefit among patients with CRSwNP in both randomised clinical trials and real-world settings (Bachert et al., 2019; Han et al., 2021; Book et al., 2023). Whilst approved biologies have been shown to reduce the need for steroids and surgery and improve patient outcomes, they are required to be administered every 2 to 4 weeks (Bachert et al., 2019; Han et al., 2021).

[0011] In light of the above, there is a need for more effective and convenient treatments for CRSwNP.

[0024] DETAILED DESCRIPTION OF THE INVENTION

[0025] DEFINITIONS 70542W001

[0026] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art.

[0027] The singular terms "a," "an," and "the" include plural referents unless context clearly indicates otherwise. Similarly, the word "or" is intended to include "and" unless the context clearly indicates otherwise. The term "plurality" refers to two or more. The term “at least one” refers to one or more.

[0028] Additionally, numerical limitations given with respect to concentrations or levels of a substance, such as solution component concentrations or ratios thereof, are intended to be approximate. Unless specified otherwise, where a numerical range is provided, it is inclusive, i.e. , the endpoints are included.

[0029] "About" as used herein when referring to a measurable value such as an amount and the like, is meant to encompass variations of ±20% or ±10%, including ±5%, ±1%, and ±0.1% from the specified value, as such variations are appropriate to perform the disclosed methods.

[0030] The term "antigen binding protein" as used herein refers to antibodies, antibody fragments and other protein constructs which are capable of binding to an antigen.

[0031] The term “antibody” is used herein in the broadest sense to refer to molecules with an immunoglobulin-like domain (for example IgG, IgM, IgA, IgD or IgE) and includes monoclonal, recombinant, polyclonal, chimeric, human, humanised, multispecific antibodies, including bispecific antibodies, and heteroconjugate antibodies; a single variable domain (e.g. a domain antibody (DAB)), antigen binding antibody fragments, Fab, F(ab’)2, Fv, disulphide linked Fv, single chain Fv, disulphide-linked scFv, diabodies, TANDABS, etc. and modified versions of any of the foregoing (for a summary of alternative “antibody” formats see Holliger and Hudson, Nature Biotechnology, 2005, Vol 23, No. 9, 1126-1136). Alternative antibody formats are also contemplated and include alternative scaffolds in which the one or more CDRs of the antigen binding protein can be arranged onto a suitable non-immunoglobulin protein scaffold or skeleton, such as an affibody, a SpA scaffold, an LDL receptor class A domain, an avimer or an EGF domain. The antibody may be derived from rat, mouse, primate {e.g., cynomolgus, Old World monkey or Great Ape), human or other sources such as nucleic acids generated using molecular biology techniques which encode an antibody molecule.

[0032] The antigen binding protein may comprise a constant region, which may be of any isotype or subclass. The constant region may be of the IgG isotype, for example, IgGi, lgG2, IgGs, lgG4 or variants thereof. The antigen binding protein constant region may be IgGi. 70542W001

[0033] The antigen binding protein may comprise one or more modifications selected from a mutated constant domain such that the antibody has enhanced effector functions / ADCC and / or complement activation.

[0034] The antigen binding proteins of the invention can be used in any of the pharmaceutical compositions, dosage regimens, or method of treatments of the invention. The antigen binding proteins can be antibodies, for example I gGi antibodies.

[0035] The term “interleukin-5” or “IL- 5” as used herein includes human IL-5 comprising the amino acid sequence shown in SEQ ID NO: 11.

[0036] The term “interleukin-5 receptor” or “IL-5R” as used herein includes human IL-5 Receptor Subunit Alpha Isoform 1 comprising the amino acid sequence shown in SEQ ID NO: 12.

[0037] The term “binds”, as used herein in relation to antigen binding proteins means that the antigen binding protein binds to a target antigen as well as a discrete domain, or discrete amino acid sequence, within a target antigen with no or insignificant binding to other (for example, unrelated) proteins. This term, however, does not exclude the fact that the antigen binding proteins may also be cross-reactive with closely related molecules (for example, those with a high degree of sequence identity or from another genera or species). The antigen binding proteins described herein may bind to human IL-5 with at least 2, 5, 10, 50, 100, or 1000-fold greater affinity than they bind to closely related molecules.

[0038] By “isolated”, it is intended that the molecule, such as an antigen binding protein, is removed from the environment in which it may be found in nature. For example, the molecule may be purified away from substances with which it would normally exist in nature.

[0039] The terms “VH” and “VL” are used herein to refer to the heavy chain variable region and light chain variable region, respectively, of an antigen binding protein.

[0040] “CDRs” are defined as the complementarity determining region amino acid sequences of an antigen binding protein. These are the hypervariable regions of immunoglobulin heavy and light chains. There are three heavy chain and three light chain CDRs (or CDR regions) in the variable portion of an immunoglobulin. Thus, "CDRs" as used herein refers to all three heavy chain CDRs, all three light chain CDRs, all heavy and light chain CDRs, or at least one CDR and wherein the at least one CDR is CDRH3. Framework regions follow each of these CDR regions. Acceptable heavy chain variable region and light chain variable region framework 1 , framework 2 and framework 3 regions are readily recognized by those of ordinary skill in the art. Acceptable heavy chain constant regions (including hinge regions) and light chain constant regions are readily 70542W001 recognized by those of ordinary skill in the art as well. Acceptable antibody isotypes are similarly readily recognized by those of ordinary skill in the art.

[0041] Throughout this specification, amino acid residues in variable domain sequences and full length antibody sequences are numbered according to the Kabat numbering convention. Similarly, the terms “CDR”, “CDRL1”, “CDRL2”, “CDRL3”, “CDRH1”, “CDRH2”, “CDRH3” used in the specification follow the Kabat numbering convention.

[0042] It will be apparent to those skilled in the art that there are alternative numbering conventions for amino acid residues in variable domain sequences and full length antibody sequences. There are also alternative numbering conventions for CDR sequences, for example those set out according to the Chothia numbering convention. The structure and protein folding of the antibody may mean that other residues are considered part of the CDR sequence and would be understood to be so by a skilled person.

[0043] Other numbering conventions for CDR sequences available to a skilled person include “AbM” (University of Bath) and “contact” (University College London) methods. The minimum overlapping region using at least two of the Kabat, Chothia, AbM and contact methods can be determined to provide the “minimum binding unit”. The minimum binding unit may be a sub-portion of a CDR.

[0044] The term “chronic rhinosinusitis with nasal polyps” or “CRSwNP” as used herein refers to the presence of two or more symptoms, one of which should be either nasal blockage / obstruction / congestion or nasal discharge (anterior / posterior nasal drip):

[0045] ± facial pain / pressure;

[0046] ± reduction or loss of smell; for >12 weeks; with validation by telephone or interview, and bilateral, endoscopically visualized polyps in middle meatus (European Position Paper on Rhinosinusitis and Nasal Polyps 2020, Fokkens et al.)

[0047] The term “chronic rhinosinusitis with nasal polyps” or “CRSwNP” as used herein may also refer to greater than or equal to 12 weeks of:

[0048] Two or more of the following symptoms:

[0049] Nasal discharge (rhinorrhea or post-nasal drip)

[0050] Nasal obstruction or congestion

[0051] Hyposmia

[0052] Facial pressure or pain

[0053] AND

[0054] One or more of the following objective findings: 70542W001

[0055] Evidence of inflammation on nasal endoscopy or computed tomography Evidence of purulence coming from paranasal sinuses or ostiomeatal complex

[0056] AND

[0057] The presence of nasal polyps (International consensus statement on allergy and rhinology: rhinosinusitis 2021 , Orlandi et al.)

[0058] The term “pharmaceutical composition” as used herein means a composition suitable for administration to a patient.

[0059] The term “therapeutically effective amount” as used herein means an amount of an agent (such as an antigen binding protein or a pharmaceutical composition), which provides a therapeutic benefit in the treatment or management of one or more symptoms of CRSwNP.

[0060] Examples of such treatment or management of one or more symptoms of CRSwNP include:

[0061] 1. Improvement / reduction in the nasal polyps score, including total endoscopic nasal polyps score

[0062] 2. Improvement / reduction in the nasal obstruction score, including mean nasal obstruction score

[0063] 3. Improvement / reduction in the rhinorrhea score, including mean rhinorrhea score

[0064] 4. Improvement / reduction in the loss of smell score, including mean loss of smell score

[0065] 5. Improvement / reduction in the Lund Mackay CT score

[0066] 6. Improvement / reduction in the SNOT-22 total score

[0067] 7. Time to first nasal surgery (optionally, actual or entry on waiting list)

[0068] 8. Reduction in systemic corticosteroid use

[0069] 9. Improvement / reduction in Asthma Control Questionnaire (ACQ-5) score

[0070] Therapeutically effective amounts and treatment regimens are generally determined empirically and may be dependent on factors, such as the age, weight, and health status of the patient and disease or disorder to be treated. Such factors are within the purview of the attending physician.

[0071] As used herein, the term “treatment” refers to ameliorating or stabilising the specified condition, reducing or eliminating the symptoms of the condition, slowing or eliminating the progression of the condition, and preventing or delaying reoccurrence of the condition in a previously afflicted patient or subject. As is recognised in the art, drugs 70542W001 employed as therapeutic agents in methods of treatment may reduce the severity of a given disease state, but need not abolish every manifestation of the disease to be regarded as useful therapeutic agents. Simply reducing the impact of a disease (for example, by reducing the number or severity of its symptoms, or by increasing the effectiveness of another treatment, or by producing another beneficial effect), or reducing the likelihood that the disease will occur (for example by delaying the onset of the disease) or worsen in a subject, is sufficient.

[0072] As used herein, the term "patient" refers to a human. The terms “individual”, “subject” and “patient” are used herein interchangeably. The patient may be an adult (>18 years).

[0073] As used herein, the phrase “once every 6 months” means that in a typical 6 month period consisting of about 183 days, a subject is administered a dose of the antigen binding protein of the invention on one day only and on the other days the subject is not administered a dose of the antigen binding protein of the invention. Administration of once every 6 months may also be referred to as “Q26W” (which refers to administration once every 26 weeks). References herein to “about once every 6 months” refer to an intended dosage regime of once every 6 months, but with the allowance of patient compliance, therefore allowing up to a four week variation depending upon patient scheduling.

[0074] As used herein, the term “total endoscopic nasal polyps score” refers to a grading based on nasal polyps size and recorded as the sum of the right and left nostril scores with a range of 0 to 8; with higher scores indicating worse status. Total endoscopic nasal polyps score may be performed by trained health care professionals (typically an ENT surgeon). Image recordings of endoscopies are used for blinded nasal polyps scoring.

[0075] As used herein, the term “nasal obstruction score” refers to a patient-reported evaluation of nasal obstruction symptoms severity using a 4-point verbal rating scale (VRS). Patients are asked to record their symptom severity over the past 24 hours in a daily diary. Response options using a 0-3 point scale include: ‘No symptoms’, ‘Mild symptoms’, ‘Moderate symptoms’ and ‘Severe symptoms’.

[0076] As used herein, the term “Lund-Mackay Computed Tomography” or Lund-Mackay CT” or “LMK-CT” refers to a scoring system based on localisation with points given for degree of opacification: 0 = normal, 1 = partial opacification, 2 = total opacification. These points are applied to the maxillary, anterior ethmoid, posterior ethmoid, sphenoid, frontal sinus on each side. The osteomeatal complex (OC) is graded as 0 = not occluded, or 2 = occluded and the maximum score is 12 per side. Image recordings of CT scans are used for Lund Mackay CT scoring. 70542W001

[0077] As used herein, the term “SNOT-22” refers to a 22-item measure of disease specific health-related quality of life (HRQoL). Participants are asked to rate the severity of their condition on each of the 22 items over the previous 2 weeks using a 6-point rating scale of 0 to 5 including: 0 = not present / no problem; 1 = very mild problem; 2 = mild or slight problem; 3 = moderate problem; 4 = severe problem; 5 = problem as “bad as it can be”. The total score range for the SNOT-22 is 0 to 110, where higher scores indicated greater disease impact.

[0078] As used herein, the term “loss of smell score” refers to a patient-reported evaluation of loss of smell symptoms severity using a 4-point verbal rating scale (VRS). Patients are asked to record their symptom severity over the past 24 hours in a daily diary. Response options using a 0-3 point scale include: ‘No symptoms’, ‘Mild symptoms’, ‘Moderate symptoms’ and ‘Severe symptoms’.

[0079] As used herein, the term “rhinorrhea score” or “runny nose score” refers to a patient-reported evaluation of rhinorrhea or runny nose symptoms severity using a 4-point verbal rating scale (VRS). Patients are asked to record their symptom severity over the past 24 hours in a daily diary. Response options using a 0-3 point scale include: ‘No symptoms’, ‘Mild symptoms’, ‘Moderate symptoms’ and ‘Severe symptoms’.

[0080] “Mean nasal obstruction score”, “mean rhinorrhea score”, and “mean loss of smell score” are mean scores derived as averages of daily responses across a diary period (4- weeks) for each individual VRS symptom item.

[0081] If desired, the effective dose of an antibody or antigen binding protein of the disclosure (e.g., as a pharmaceutical composition) may be administered as a unit dosage form.

[0239] Randomisation

[0240] Participants were enrolled by study investigators and randomised in a 1:1 ratio into one of the two treatment groups, depemokimab 100 mg SC or placebo (both to be administered with SoC).

[0241] Procedures

[0242] Participants received depemokimab 100 mg SC or placebo once every 26 weeks (at Weeks 0 and 26) via single-use prefilled syringe (assembled in a safety device) for 52 weeks, in addition to SoC. Participant demography was assessed at Screening, with details entered into an electronic case report form (eCRF). Endoscopic NP score was assessed at Screening and Weeks 0, 12, 20, 26, 32, 40, 48 and 52 by trained health care professionals at study sites. All endoscopy images were sent to a central vendor where independent reviewers provided blinded NP scoring, graded based on NP size and recorded as the sum scores for each nostril from 0-8 (higher scores indicate worse outcomes). The severity of individual NP symptoms (including nasal obstruction, rhinorrhoea and loss of smell) were measured by verbal response scale (VRS), administered by participants using an eDiary each morning from screening to the end of 70542W001 the treatment period. Computerised tomography (CT) scans were performed prior to randomisation and at Week 52 (or Week 26 if a participant withdrew early). All CT scans were independently assessed by a central vendor using the Lund Mackay scoring system (0-24). Using an eDiary, participants rated the severity of their condition at each study visit using the Sino-Nasal Outcome Test (SNOT-22) questionnaire on a scale of 0-5 (total score ranges from 0-110; higher scores indicate greater disease impact). Whether a participant was on a waiting list for NP surgery or had received documented surgery was recorded at each study visit. The dose and duration of courses of SCS were recorded in the eCRF. Participants with asthma completed the Asthma Control Questionnaire (ACQ-5) using an eDiary at Weeks 0, 8, 16, 24, 26, 32, 40, 48 and 52. Incidence of AEs and serious AEs (SAEs) were assessed at each study visit. Clinical (liver) chemistry was assessed at Weeks 0, 4, 8, 12, 20, 26, 28, 40 and 52. Pharmacodynamic samples were assessed from haematology samples collected at Weeks 0, 4, 8, 12, 20, 26, 28, 32, 40, 48 and 52. Immunogenicity was assessed from serum samples taken at Weeks 0, 4, 8, 12, 26, 40 and 52 (or the final visit for participants that withdrew early).

[0243] Outcomes

[0244] The coprimary endpoints were change from baseline in: total endoscopic NP score at Week 52, and mean nasal obstruction score (VRS) over Week 49-52. Secondary endpoints were change from baseline in: mean symptom score from rhinorrhoea, and loss of smell (both VRS) over Week 49-52; Lund Mackay CT score, and SNOT-22 total score at Week 52; mean nasal obstructions score (VRS) over Week 21-24, and total endoscopic NP score at Week 26. Pre-specified secondary endpoints for pooled analyses across studies were time to first nasal surgery (actual or on entry onto waiting list)_or disease-modulating medication for CRSwNP up to Week 52; proportion of participants requiring >1 course of SCS or disease-modulating medication for CRSwNP or nasal surgery (actual) during the 52-week treatment period; and change from baseline in ACQ-5 at Week 52 among participants with partially controlled or uncontrolled asthma at baseline (ACQ-5 score >0.75).

[0245] Safety was assessed by monitoring the incidence of adverse events (AEs) and serious AEs (SAEs). Incidence of immunogenicity was measured by the presence of antidrug and neutralising antibodies.

[0246] Statistical analysis

[0247] The sample size for the studies was calculated to achieve sufficient power to observe statistical significance between treatment groups for the coprimary endpoints 70542W001

[0248] (>99% power), and the pooled secondary endpoint of time to first nasal actual surgery or added to waitlist (>90% power). Following testing of coprimary endpoints, statistical analyses of secondary endpoints for each trial were conducted in a closed-testing manner to account for multiplicity using the following pre-defined hierarchy: rhinorrhoea VRS score, loss of smell VRS score, Lund Mackay CT score, SNOT-22 total score, nasal obstructions VRS score (over Week 21-24), and total endoscopic score (at Week 26). A similar multiplicity adjustment was conducted for the pooled analysis, with the pre-defined hierarchy: time to first nasal surgery (actual or added to waitlist), time to first nasal surgery (actual), proportion of participants requiring at least one course of SCS, and change from baseline in ACQ-5 score.

[0249] The coprimary and secondary endpoints for each study, as well as the pooled analysis of ACQ-5, were expressed as the treatment difference between groups in mean change from baseline and analysed using a mixed model repeated measures (MMRM) analysis (except for Lund Mackay CT score). Lund Mackay CT score was analysed using analysis of covariance (ANCOVA). Data for participants who withdrew early was included and assumed to be missing at random (MAR). Subgroup analyses for each of the coprimary endpoints were performed for age, sex, race, region and baseline blood eosinophil category. Subgroup analyses of integrated data from ANCHOR-1 and ANCHOR-2 for each of the coprimary endpoints were conducted for age, sex, baseline body mass index, race, region, number of previous surgeries, baseline blood eosinophil category, patients with asthma, aspirin-exacerbated respiratory disease (AERD), and baseline IgE. The pooled analysis of time to first nasal surgery endpoints were analysed using Cox’s proportional hazards model; missing values were considered censored at random and data are expressed with hazard ratios (HR) and Kaplan-Meier estimates of the proportion of participants requiring surgery over time. The proportion of participants requiring >1 course of SCS was analysed using a logistic regression model; data are expressed as summaries with odds ratios (OR).

[0250] An intercurrent events strategy was employed for all efficacy endpoints, under which the intercurrent events of surgery or initiation of a disease-modulating medication for CRSwNP were incorporated into the definition of the endpoint.

[0251] For participants who underwent nasal polyps surgery or received a diseasemodulating medication, data collected for assessments following the start of surgery or initiating a disease-modulating medication were set to the worst-possible score of the relevant assessment for all continuous endpoints. For time to first nasal surgery, the initiation of a disease-modulating medication was assigned as requiring nasal surgery at the start of the medication. For the proportion of participants requiring >1 course of SCS, 70542W001 nasal surgery or initiation of a disease-modulating medication was assigned as requiring a course of SCS.

[0252] Efficacy endpoints (coprimary and all secondary) were analysed among the full analysis set (FAS) population. All safety analyses were performed on the safety analysis set. Both populations include all randomised participants who took >1 dose of study treatment.

[0253] These trials were registered with ClinicalTrials.gov (ANCHOR-1 : NCT05274750; ANCHOR-2: NCT05281523) Example 2 - Patient characteristics (ANCHOR-2)

[0263] Coprimary endpoints

[0264] For the coprimary endpoints, significant improvements from baseline were observed with depemokimab versus placebo for total endoscopic NP score at Week 52 (treatment difference [95% confidence interval; Cl]: ANCHOR-2, -0.6 [-1.0, -0.2; p=0.004]) and mean nasal obstruction VRS score over Week 49-52 (treatment difference [95% Cl]: ANCHOR-2, -0.25 [-0.46, -0.03; p=0.025]). Secondary endpoints

[0265] The following was observed with depemokimab versus placebo in: mean rhinorrhoea VRS score (treatment difference [95% Cl]: ANCHOR-2, -0.18 [-0.40, 0.05]; p=0.125), and mean loss of smell VRS score (ANCHOR-2, -0.26 [-0.45, -0.07]) over Weeks 49-52; Lund Mackay CT score (ANCHOR-2, -3.2 [-4.4, -2.0]), and SNOT-22 total score (ANCHOR-2, -9.9 [-17.9, -2.0]) at Week 52. As with the coprimary endpoints, improvements were observed with depemokimab over Week 21-24 in mean nasal 70542W001 obstruction VRS score (ANCHOR-2, -0.24 [-0.43, -0.04]), and at Week 26 in total endoscopic NP score (ANCHOR-2, -0.3 [-0.7, 0.0]). Nominal significance (i.e., p<0.05 without multiplicity control) was achieved for mean loss of smell VRS score, Lund Mackay CT score, SNOT-22 total score and mean nasal obstruction VRS score over Week 21-24. Statistical significance was not achieved due to a break in the multiplicity-controlled testing hierarchy.

[0266] Safety

[0267] The proportion of participants reporting AEs during the on- and post-treatment periods was similar between depemokimab (ANCHOR-2: n=98 [76%]) and placebo groups (ANCHOR-2: n=102 [80%]). Incidence of SAEs was also similar between depemokimab (ANCHOR-2: n=6 [5%]) and placebo (ANCHOR-2: n=10 [8%]); No deaths were reported in the depemokimab or placebo groups.

[0268] Subgroups

[0269] This study also demonstrated that further improvements in reducing nasal polyps score and nasal obstruction score can be achieved in specific patient subgroups, for example, the patient may have a baseline peripheral blood eosinophil count of at least 300 cel Is / microl iter, the patient may have comorbid asthma or the patient may have more than two previous nasal polyp surgeries. A forest plot of subgroups for endoscopic nasal polyps score at week 52 is shown in Figure 1. A forest plot of subgroups for mean nasal obstruction score at weeks 49-52 is shown in Figure 2.

[0270] Example 4 - Summary of Results (ANCHOR-1)

[0271] Coprimary endpoints

[0272] For the coprimary endpoints, significant improvements from baseline were observed with depemokimab versus placebo for total endoscopic NP score at Week 52 (treatment difference [95% confidence interval; Cl]: ANCHOR-1, -0.7 [-1.1 , -0.3; p<0.001]) and mean nasal obstruction VRS score over Week 49-52 (treatment difference [95% Cl]: ANCHOR-1 , -0.23 [-0.46, -0.00; p=0.047]).

[0273] Secondary endpoints

[0274] The following was observed with depemokimab versus placebo in: mean rhinorrhoea VRS score (treatment difference [95% Cl]: ANCHOR-1 , -0.22 [(-0.46, 0.02]; p=0.074), and mean loss of smell VRS score (ANCHOR-1 , -0.19 [-0.39, 0.00]) over 70542W001

[0275] Weeks 49-52; Lund Mackay CT score (ANCHOR-1 , -2.0 [-3.3, -0.8]), and SNOT-22 total score (ANCHOR-1 , -6.8 [-15.2, 1.6]) at Week 52. As with the coprimary endpoints, improvements were observed with depemokimab over Week 21-24 in mean nasal obstruction VRS score (ANCHOR-1 , -0.17 [-0.37, 0.03]), and at Week 26 in total endoscopic NP score (ANCHOR-1 , -0.8 [-1.1 , -0.4]). Nominal significance (i.e., p<0.05 without multiplicity control) was achieved for Lund Mackay CT score and Week 26 total endoscopic NP score. Statistical significance was not achieved due to a break in the multiplicity-controlled testing hierarchy.

[0276] Safety

[0277] The proportion of patients who experienced AEs during the on- and post-treatment periods was similar between depemokimab (ANCHOR-1 : 74% [n=106]) and placebo groups (ANCHOR-1 : 79% [n=101]). SAE incidence was also similar between depemokimab (ANCHOR-1 : 3% [n=5]) and placebo (ANCHOR-1 : 5% [n=6]). No deaths were reported in the depemokimab or placebo groups.

[0278] Subgroups

[0279] This study also demonstrated that further improvements in reducing nasal polyps score and nasal obstruction score can be achieved in specific patient subgroups, for example, the patient may have a baseline peripheral blood eosinophil count of at least 300 cells / microliter or the patient may have comorbid asthma. A forest plot of subgroups for endoscopic nasal polyps score at week 52 is shown in Figure 3. A forest plot of subgroups for mean nasal obstruction score at weeks 49-52 is shown in Figure 4.

[0288] Example 6 - Integrated and pooled analysis

[0289] Depemokimab treatment significantly improved total endoscopic NPS change from baseline at Week 52 (treatment difference [95% confidence interval; Cl]: integrated, -0.7 [- 0.9, -0.4; p<0.001]) and mean nasal obstruction VRS score change from baseline over

[0290] Weeks 49-52 (treatment difference [95% Cl]: integrated, -0.24 [-0.39, -0.08; p=0.003]), compared with placebo. Integrated p values are nominal.

[0291] The treatment difference (95% Cl) in mean rhinorrhoea VRS score for depemokimab versus placebo was -0.19 (-0.36, -0.03; p=0.021) for the integrated analysis. Treatment difference (depemokimab versus placebo) for mean loss of smell VRS score over Weeks 49-52 was -0.22 (-0.35, -0.08; p=0.002; integrated); for Lund Mackay CT score at Week 52, it was -2.5 (-3.4, -1.7; p<0.001 ; integrated); and for SNOT-22 total score at Week 52, treatment difference was -8.1 (-13.9, -2.3; p=0.007; integrated). The treatment difference in change from baseline in mean nasal obstruction VRS score over Weeks 21-24 was -0.20 (-0.34, -0.06; p=0.005; integrated). Treatment difference in total endoscopic NPS at Week 26 was -0.5 (-0.8, -0.3; p<0.001; integrated). Integrated p values are nominal.

[0292] For the pooled secondary endpoints, the proportion of patients meeting the CRSwNP surgery (actual or entry on waiting list, up to Week 52) endpoint was 16% 70542W001

[0293] (n=44) and 22% (n=56) for depemokimab and placebo groups, respectively, resulting in a percentage reduction in risk (depemokimab versus placebo) of 27% (hazard ratio; HR [95% Cl]: 0.735 [0.495, 1.092]; p=0.128). Since statistical significance was not achieved for this endpoint, the remaining pooled secondary efficacy endpoints were not multiplicity- adjusted. Depemokimab demonstrated a greater risk reduction versus placebo among patients with asthma compared with those without, and patients with blood eosinophil count >300 cells / pL versus <300 cells / pL (post hoc analyses). For risk of CRSwNP surgery (actual only), 12% (n=33) and 17% (n=43) of patients experienced the endpoint in the depemokimab and placebo groups, respectively, resulting in a percentage reduction in risk of 29% (HR: 0.713 [0.453, 1.124]). During the 52-week treatment period 26% (n=72) and 36% (n=92) of patients in the depemokimab and placebo groups, respectively, required >1 course of SCS for CRSwNP (depemokimab versus placebo odds ratio; OR [95% Cl]: 0.58 [0.40, 0.86]). Among patients with partially or not well controlled asthma at baseline (ACQ-5 score >0.75: depemokimab, n=104; placebo, n=102), the treatment difference (95% Cl; depemokimab versus placebo) in change from baseline in ACQ-5 score at Week 52 was -0.75 (-1.26, -0.25).

[0294] The proportion of patients no longer having a need for CRSwNP surgery at Week 52 in the pooled analysis was 24% (n=65) and 14% (n=35) in the depemokimab and placebo groups, respectively (OR [95% Cl]: 2.17 [1.33, 3.52]; p=0.002). The proportion of patients who remained SCS-free (regardless of indication) was 70% (n=190) in the depemokimab group and 59% (n=151) in the placebo group.

[0295] Integrated subgroup analyses are shown in Figures 5 and 6.
