    General information about the trial
    Main objective of the trial
    To investigate the long-term efficacy and safety of depigmented and glutaraldehyde polymerized allergenic extract of 100% birch pollen (Depigoid Birch) at a concentration of 5000 DPP/mL applied according to the perennial treatment regimen in comparison to placebo in adult and adolescent patients with birch pollen-induced allergic rhinitis and/or rhinoconjunctivitis.
    Protection of trial subjects
    The study was conducted in accordance with the ethical principles that have their origin in the Declaration of Helsinki, and that are consistent with the International Conference on Harmonization of technical requirements for registration of pharmaceuticals for human use (ICH) guidance for Good Clinical Practice (GCP) and the applicable regulatory requirements. The study protocol, all amendments, informed consent forms (ICF) were approved by an independent ethics committee (IEC) and health authorities; ICF was explained to and consent obtained from each patient before participation. To minimize risks, stopping criteria were defined and an independent Data Monitoring Committee (DMC) was created to assess the progress, safety and critical efficacy endpoints of the study. Three interim analyses were planned to assess efficacy of the treatment and the study futility. In addition, patients were permitted to use rescue medication (RM) to alleviate allergic symptoms; these medications are also used as symptomatic RM in daily clinical routine for allergic rhino-conjunctivitis and allergic intermittent asthma; after the study ended, the placebo-treated patients were also offered a 3-year perennial specific immunotherapy (SIT) with Depigoid Birch as a follow-up treatment in countries where legally possible. The sponsor issued a global protocol amendment requiring the withdrawal of all co-sensitized patients and continuing only with patients mono-sensitized to birch (according to the skin prick test at screening), because statistically significant differences in favor of Depigoid Birch 5000 over placebo for the treatment of allergic rhinitis and/or rhino-conjunctivitis, with or without intermittent asthma, could only be shown in mono-sensitized patients (demonstrated by results of planned 2nd-year interim analysis, the additional analyses of 3rd-year data and the post-hoc analyses of 2nd and 3rd year data performed by the DMC).
    Background therapy
    Country-specific RMs were used in the study for treatment of potentially occurring characteristic symptoms related to the underlying disease (allergic rhinitis/rhinoconjunctivitis with or without asthma due to birch pollen).
    Evidence for comparator
    Placebo control was used in this study. It was appropriate as the European Medicines Agency (EMA) guideline on clinical development of products for SIT for the treatment of allergic diseases (CHMP/EWP/18504/2006) recommends that Phase III studies in immunotherapy should show superiority of test drugs to placebo.

    Recruitment
    Recruitment details
    Patients (12-70 y) from 7 countries were enrolled and screened over 2 recruitment periods (started Sep-2012, ended Jan-2014). 649 of 973 (66.7%) enrolled patients were randomized to treatment (434 to Depigoid Birch; 215 to placebo).

    Pre-assignment
    Screening details
    Subjects were included if they had immunoglobulin E (IgE)-mediated seasonal allergic rhinitis and/or rhinoconjunctivitis with or without intermittent asthma due to birch pollen allergy verified by specific IgE reactivity (CAP-RAST ≥2) and positive Skin Prick Test (SPT) (wheal diameter of at least 3.0 mm) within one month prior to screening (SCR).

    Notes
    [1] - The number of subjects starting the period is not consistent with the number completing the preceding period. It is expected the number of subjects starting the subsequent period will be the same as the number completing the preceding period.
    Justification: Data analysis for Mono-sensitized patients were conducted for periods Year 1-3 (treatment phase; Period 1) and Year 1-5 (treatment + follow-up phase; Period 2). No separate analysis was conducted for the follow-up phase (Year 4-5). Therefore, the number of subjects starting the follow-up phase (Period 2) is derived from the number of subjects starting the treatment phase (Year 1 in the treatment phase).

    Mean integrated Symptoms and Medication Score (SMS)
    End point description
    Based on the planned second interim analysis for futility, the DMC (agreed with the sponsor and the PEI) recommended to discontinue the Co-sensitized patients from the study. Only the Mono-sensitized patients continued with the follow-up phase. Therefore, full results (Year 1-5) are presented for the Mono-sensitized patients, while only results in the treatment phase (Year 1-3) are presented for the Co-sensitized patients. The primary efficacy endpoint of the study was the mean integrated SMS on nasal and ocular symptoms and their RM score (RMS) per pollen season. The mean integrated SMS per year were compared between treatment groups by means of Wilcoxon-Mann-Whitney (two-sided) and Hodges-Lehmann two-sided 95% CI of the median difference between the treatments. Exploratory analysis based on logistic regression model for superiority testing, with treatment arm and age group as factors accounting for the stratification variables applied for randomization was performed in the FAS.

Only Mono-sensitized patients continued with the follow-up phase. Therefore, full results (Year 1-5) are presented for the Mono-sensitized patients, while only results in the treatment phase (Year 1-3) are presented for the Co-sensitized patients. The mean integrated SMS (0-6) was calculated as the sum of SS for rhinoconjunctivitis and the RMS according to the EAACI criteria for equal weight of both SS and RMS. The values of the SMS (0-6) for rhinoconjunctivitis range from 0 to 6, whereby higher values indicate worse outcome.

    Mean Integrated Symptom Score (SS)
    End point description
    Only the Mono-sensitized patients continued with the follow-up phase. Therefore, full results (Year 1-5) are presented for the Mono-sensitized patients, while only results in the treatment phase (Year 1-3) are presented for the Co-sensitized patients. Mean integrated SS was an integrated part of the primary efficacy endpoint but was assessed as secondary efficacy endpoint separately. The daily SS was defined as the mean of the symptoms’ severity scorings per day during a pollen season and was derived from the patient’s eDiary entries. The SS scores ranged from 0 to 18 points derived from 4 nasal (itching, sneezing, rhinorrhea, and obstruction) and 2 ocular (itching/grittiness/redness and tearing) symptoms, each assessed by the patient on 4-point-Likert scale ranging from 0 to 3. Calculations of the SS according to the EAACI criteria were used for statistical analyses.

    Mean Integrated Combined Symptom Medication Score (SMS)
    End point description
    Only the Mono-sensitized patients continued with the follow-up phase. Therefore, full results (Year 1-5) are presented for the Mono-sensitized patients, while only results in the treatment phase (Year 1-3) are presented for the Co-sensitized patients. The mean combined SMS includes pulmonary symptoms, in addition to nasal and ocular symptoms. The mean integrated combined SMS (i.e. SMS-pul) was calculated as the sum of daily scores for nasal, eye, and pulmonary symptoms and their RM per pollen season.

    Mean Integrated Asthmatic Rescue Medication Score (RMS)
    End point description
    Only the Mono-sensitized patients continued with the follow-up phase. Therefore, full results (Year 1-5) are presented for the Mono-sensitized patients, while only results in the treatment phase (Year 1-3) are presented for the Co-sensitized patients. The scores of RMS for asthmatic patients only were not considered for the calculation of the primary endpoint but were evaluated separately as a secondary efficacy endpoint, i.e. the asthmatic RMS. The RMS, defined as the mean of daily RMS during a pollen season, was calculated from score points allocated per application of each single RM product to treat the characteristic allergy related symptoms.

    Number of Well Days and Hell Days
    End point description
    Only the Mono-sensitized patients continued with the follow-up phase. Therefore, full results (Year 1-5) are presented for the Mono-sensitized patients, while only results in the treatment phase (Year 1-3) are presented for the Co-sensitized patients. Well days were defined as days with a SS ≤ 2 and no RM. Hell days were defined as days with a SS ≥ 10 and additional use of RM.

    Al PK - Plasma concentration
    End point description
    Because the IMP contains Al(OH)3, the Pediatric Committee has required PK analyses of aluminum. Thus, a PK sub-study was performed to assess the levels of aluminum in plasma and in urine in a subgroup of adult patients. Plasma concentration measurement below the limit of quantification was set to half of the respective value. The results for Year 1-3 were presented for the Al PK set.

    PK parameters (Cmax, Tmax, AUC[0-8h]) were derived by non-compartmental analysis at V1-2 and V1-10 using Phoenix WinNonlinTM Software Version 6.3 (Pharsight Corporation, Mountain View, CA 94041-1530, USA). AUC was derived using the (linear) trapezoidal rule. If all aluminum concentration data obtained for a patient were below the limit of quantification at V1-2 or visit V1-10, the AUC was presented as “not determined”. The PK parameters were derived using actual time points (i.e. calculated actual time of sample collection relative to administration time of IMP). Samples that were taken prior to administration of IMP were considered as to be collected at time zero. The results for Year 1 to 3 were presented for the Al PK set.

    Timeframe for reporting adverse events
    AEs were collected from signing of the informed consent until the end of the study (Year 5). Only treatment-emergent AEs (TEAEs) (AEs that started or worsened after first dose of the IMP) reported from V1 until the end-of-study (EoS) visit were analyzed.
    Adverse event reporting additional description
    Systemic reactions (SR, according to the EAACI grading criteria) and local reactions (LR, according to induration [wheal] size as determined by the largest diameter of the wheal, itching, and pain) were additionally analyzed as separate categories, and are presented here as part of the TEAEs analysis.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    06 Sep 2012
    The global protocol amendment No. 1 was conducted in accordance with the changes requested by German Competent Authorities and the Central EC in Germany. The main changes include: 1. Modification of a few inclusion/exclusion criteria for precise formulation and thereby enhanced patient’s safety. 2. Further clarifications and/or modifications of some study procedures, including: a. Added requirement for venous access prior to administration of IMP in the rush build-up phase b. Adaptations in the escalation scheme for RM c. Added instructions to investigators for recording data in eCRF d. Added assessments of patients’ asthma status, vitamin D in blood, SPT at EoS e. Modified definitions of AE causality categories f. Modifications in the schedule of PK blood sampling g. Added definition for futility analysis population h. Clarifications for PFT scheduling, definition of topical corticosteroids as RM, time window for collection of medical history data, negative SPT control, timing of RQLQ assessments, observation period for AEs, and scoring of SMS (also including asthmatic patients)
    30 Nov 2012
    This global amendment No. 2 was implemented in the protocol at the request of the sponsor. The main changes include: 1. Extension of patients’ recruitment period (the first recruitment period lasted 3 to 4 months starting September 2012 and the newly added recruitment period was planned to start after termination of birch pollen season 2013 and until December 2013). 2. Extension of the SCR period (from up to 4 weeks to up to 8 weeks). 3. Added clarifications of inclusion criteria No. 9 and 10, and modification of exclusion criterion No. 20 regarding prior use of psychoactive drugs 4. Further specifications on mid-season visit scheduling with respect to birch pollen season 5. Clarifications on the use of permitted RMs and procedures for recording information about RMs 6. Minor modification to type of psychoactive drugs considered prohibited concomitant medication. 7. The PK sub-study was not any longer specified to German sites only. 8. The statistical analysis for futility was further specified.
    11 Jul 2013
    This global amendment No. 3 was implemented at the request of the sponsor and partly requested by the Paul-Ehrlich-Institut (PEI, German Competent Authority) due to the extended recruitment period that had already been approved with the global amendment No. 2. The main changes include: 1. Adding the number of screened patients needed to attain the required number of randomized patients for statistical analyses. 2. Further specifications/modifications of two exclusion criteria (No. 10 - SCORAD cut off was increased from 30 to 40; No. 19 - “parenthesis” was added) 3. Correction of a typo in the escalation scheme for inhaled corticosteroids 4. The description of primary and futility analyses was adapted due to the addition of a second recruitment period as requested by the PEI, Germany 5. Adding clarifications for handling of AdolRQLQ
    11 Oct 2016
    This global protocol amendment No. 4 was prepared at the request of the sponsor and submitted to the ECs in Czech Republic, Germany, Latvia, Lithuania, and Poland. In Russia, the protocol amendment was implemented in protocol version 3.0 for Russia, dated 13-OCT-2016, and was submitted for approval as well. Before receiving response from any of the ECs, the sponsor decided to withdraw the global amendment. The reason for withdrawal was the need of additional changes to the protocol based on recommendations of the DMC to continue the study with Mono-sensitized patients only. Thus, all changes in the protocol included in global amendment No. 4 were included in the global amendment No. 5.
    11 Jan 2017
    This global protocol amendment No.5 was prepared to implement changes in the study conduct following from DMC recommendations based on results of the planned 2nd-year interim analysis and additional analyses of 3rd-year data and post-hoc analyses. The main changes include: 1. Only patients who turned out to be mono-sensitized to birch according to the SPT at SCR could continue participating in the study; the remaining, co-sensitized, patients had to be withdrawn from the study. This decision was supported by the results of the planned 2nd-year interim analysis, the additional analyses of 3rd-year data and the post-hoc analyses of 2nd and 3rd year data performed by the DMC. 2. Cancelation of the planned 3rd- year futility analysis 3. A new stopping rule for individual patients was added: Patients with any co-sensitization documented at SCR according to the SPT were to be withdrawn from the study 4. Immunoblotting analysis of Alnus and Corylus was added for patients who had blood samples still available on storage in the central laboratory 5. Addition of analysis of immediate and delayed SRs
    28 Feb 2017
    This global amendment No. 6 was prepared at the request of the German Authority PEI and the sponsor and aimed to introduce the following changes in the conduct of the study: 1. Scheduling of a post-study visit for all co-sensitized patients that had to be withdrawn from the study (requested by the PEI) 2. Clarification on additional laboratory evaluations for co-sensitized patients at EoS visit (including hematology, clinical chemistry investigations, serum pregnancy test, vitamin D, immunology parameters and immunoblotting. An immunoblot analysis of birch (Betula) was added to enable comparisons with results of Alnus and Corylus testing at EoS visit

    Interruptions (globally)

    Were there any global interruptions to the trial? No

    Limitations and caveats

    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    Due to withdrawal of the Co-sensitized patients from the study, only the complete data for Year 1-3 were available for analysis in this arm. Data analysis for Year 1-5 was only done for a subset of Co-sensitized patients who completed Year 4-5.
