Describe the objectives, methods and results of the first year of the new version of the Spanish registry of adverse events involving biological therapies and synthetic drugs with an identifiable target in rheumatic diseases (BIOBADASER III).


Multicenter prospective registry of patients with rheumatic inflammatory diseases being treated with biological drugs or synthetic drugs with an identifiable target in rheumatology departments in Spain. The main objective of BIOBADASER phase III is the registry and analysis of adverse events; moreover, a secondary objective was added consisting of assessing the effectiveness by means of the registry of activity indexes. Patients in the registry are evaluated at least once every year and whenever they experience an adverse event or a change in treatment. The collection of data for phase III began on 17 December 2015.


During the first year, 35 centres participated. The number of patients included in this new phase in December 2016 was 2664. The mean age was 53.7 years and the median duration of treatment was 8.1 years. In all, 40.4% of the patients were diagnosed with rheumatoid arthritis. The most frequent adverse events were infections and infestations.


BIOBADASER phase III has been launched to adapt to a changing pharmacological environment, with the introduction of biosimilars and small molecules in the treatment of rheumatic diseases. This new stage is adapted to the changes in the reporting of adverse events and now includes information related to activity scores.

Inflammatory rheumatic diseases affect over 10% of the population at large.1,2 According to data from the latest annual report of phase II of the Spanish registry of adverse events involving biological therapies in rheumatic diseases (BIOBADASER II), diagnoses of rheumatoid arthritis (RA), psoriatic arthritis (PA) and ankylosing spondylitis (AS) are the most prevalent among patients with rheumatic diseases included in the registry. According to data from December 2015, 50.5% of the patients included in this registry were diagnosed with RA; 16.6% with AS and 15.9% with PA.3

In Spain there are 14 approved drugs for the treatment of rheumatic diseases: 5 innovative tumour necrosis factor inhibitors (TNF)-α: infliximab, etanercept, adalimumab, certolizumab pegol and golimumab; one interleukin receptor antagonist recombinant protein (IL) 1: anakinra; one T-cell activation modulator fusion protein: abatacept; one monoclonal antibody against the IL 6 receptor: tocilizumab; one monoclonal antibody against CD20: rituximab; one monoclonal antibody against IL-1β: canakinumab, one monoclonal antibody targeted against the B-cell activating factor (BAFF): belimumab; one IgG1κ anti-IL-12/23 monoclonal antibody: ustekinumab; one anti-IL-17A antibody: secukinumab, and one monoclonal antibody which acts as an inhibitor of the ligand RANK (RANKL): denosumab. Information exists on safety and efficacy from randomised clinical trials which have assessed many of these drugs in the short term.4–8 However, follow-up of these treatments long-term and information on safety and efficacy in clinical practice are still imited,9 particularly in drugs which have been on the market for a shorter time. From February 2015 CT-P13 (Celltrion) has been made available. This is a biosimilar of infliximab which has been distributed in Mexico under 2 trade names,10,11 and since the end of 2016 a second biosimilar to infliximab, SB2 (developed by Samsung Bioepis) and another biosimilar to etanercept, SB4 (Samsung Bioepis), are also available with the same indications as their innovative molecule.12,13 Two oral inhibitor compounds of Janus Kinase inhibitor compounds (JAK), tofacitinib and baricitinib, will shortly be available for the management of RA, and will be combined with a phosphodiesterase 4 inhibitor, apremilast (already available), with an indication in PA. These will constitute a new group of synthetic drugs with an identifiable target.

BIOBADASER began its activity in the year 2000 and continued with phase II in 2006.14 The goals of this project were to collect information on the safety and adverse events in patients who had begun biologic treatment. In different European, Latin American countries and in the United States other similar registries exist for patients being treated with biologic therapy.15 The appearance of biosimilars and synthetic drugs with an identifiable target, and the need expressed by regulatory agencies in knowing direct data on the effectiveness and safety of these agents in daily clinical practice, together with changes in regulation and legislation in pharmacovigilance, has determined the launch of the BIOBADASER phase III.

BIOBADASER helped to establish the relationship between the anti-TNF therapy and the reactivation of latent tuberculosis in patients with rheumatic diseases.16–18 These studies have led to an improvement in the usage safety of this type of treatment.

The Spanish Society of Rheumatology (SER), in collaboration with the Spanish Medicines and Health Products Agency (AEMPS), and support by finance from the pharmaceutical sector, has continued to drive BIOBADASER with the start-up of phase III of the project. This paper describes the objectives, design and methodology of BIOBADASER III, the results obtained in the first year and the strengths and weaknesses of the study.


BIOBADASER is a prospective registry of follow-up of patients with rheumatic diseases who begin treatment with biologics, biosimilars and synthetic molecules with an identifiable target.


The phase III objectives are as follows:

  • Identify relevant adverse events which appear during the treatment of rheumatic diseases with biologic therapies and synthetic drugs with an identifiable target and estimate their frequency of presentation.

  • Identify unexpected adverse events.

  • Identify relevant adverse events which present after treatment has been suspended.

  • Assess, under non experimental circumstances, time passing up to the suspension of biologic therapies in patients with rheumatic diseases, and the reasons for this withdrawal: side effect, loss of effectiveness, remission or death.

  • Assess the effectiveness in clinical practice of the treatments included in the registry.

Centre selection

During the first year of phase III 35 centres participated. The selection of these centres was made through a public call for proposals advertised through the usual media available to SER members. All researchers interested in participating in the project had to fill in a document with the centre details and their commitment to study participation. A priori, there was no fixed minimum number of patients in treatment with biologic therapy for the centre selection. Final selection was made by the BIOBADASER Scientific Committee, based on the number of patients in treatment with biologic therapy in the Rheumatology Department of the interested hospitals until completion of the 35 centres who took part in the study the first year.

Patient selection

The population who were candidates for the study were those patients in treatment with biologic therapy or targeted synthetic drugs for any rheumatologic disease in the technical record or for compassionate usage, attended by the Rheumatology Services of the centres that participated in phase III and who gave their informed consent to take part in the study.

Study recruitment for the inclusion of new patients remains open indefinitely.

Selection criteria

Patients with any rheumatic disease were able to participate in the study provided they met with the criteria contained in Table 1. The patient had to meet one of the 3 first criteria and sign an informed consent form to participate in the study.

Table 1.

Selection criteria of patients to participate in BIOBADASER Phase III.

Selection criteria 
Patients with RA who are beginning treatment (or are being treated) with biologics (except infliximab, etanercept and adalimumab) or biosimilar in the participative centres, from the beginning of phase three. 
Patients with any other diagnosis who are beginning treatment (or are being treated) with biologics or biosimilar in the participative centres, from the beginning of phase three. 
Patients who are being treated with biologics or have had treatment suspended, for any reason, provided that no more than one year has passed since they received treatment for the last time and that all the necessary data are available for recording (concerning the patient, treatment and adverse events). 
Patients who authorise the prospective collection of data in accordance with the formula indicated on the informed consent form. 

The patient must meet with one of the 3 first criteria and without fail with the fourth criterion.

To enhance recruitment of new patient participants in the study, it was accepted that the patients could have initiated biology therapy in the 2 years prior to the start of BIOBADASER phase III. Information from the 2 previous years was collected from the clinical record.

Patients who had participated in phase II of the study could continue participating in phase III of BIOBADASER once the new informed consent form had been signed.

Data collection

Information recorded in BIOBADASER originated from the clinical record and visits from patients to the Rheumatology department. The information collected: (1) as baseline; (2) when an adverse event or change in treatment occurred (biologic therapy or with synthetic molecules with an identifiable target), for any other reason during this time period and (3) at least once a year (follow-up visit). Data were also recorded when death occurred for any reason and in the case of discontinuation of treatment due to remission or other causes.

Data recording and storage was conducted electronically, using an ad hoc designed IT application. An instruction manual was redacted to explain how it worked to the researchers. The IT application contained filters, ranges, menus and dialogues to help improve data reliability.

An annual online monitorisation of data recorded between the months of September and November of every year was made. The goal of this monitorisation was to filter out inconsistencies and possible data collection errors. From the second year onwards, apart from the continuous online monitorisation, an annual on-site monitorisation is to be made where all the participant centres in BIOBADASER phase III will be visited and 20 patients from each centre will be randomly selected to have their medical records monitored.


In the baseline visit the registry inclusion date was collected and sociodemographic variables such as gender and date of birth. The following clinical variables were also collected in this visit: diagnosis and date of diagnosis, weight and height on patient inclusion in the study, number of inflamed and painful joints, visual analogue scale of the disease activity, assessed by the patient, analytical values (ESR, CRP, rheumatoid factor, anti-CCP, HLB27 and antinuclear antibodies). Activity indices collected are the DAS28 for patients diagnosed with RA and PA, BASDAI and ASDAS-CRP in the case of AS and SLEDAI for patients diagnosed with SLE. This information was collected at the start of each new treatment and in the annual check-ups. Patient comorbidities were collected in the baseline visit through the components of the Charlson index.19 In cases where the patient had previously received other biologic drugs, the initiation and termination dates of these treatments were also recorded.

From the moment the BIOBADASER phase III patient was included, the date of initiation and termination was recorded, as was the reason for treatment suspension. In this phase III the dose, periodicity and administration route of the biologic or synthetic drug with identifiable target treatment were also recorded. To avoid problems of traceability between innovators and biosimilars all the drugs were recorded with their trade name. Information was also collected relating to the screening for tuberculosis (previous history, probability of contact, BCG vaccination, carrying out of diagnostic tests, chemoprophylaxis), vaccines and diagnostic tests for this disease, in addition to concomitant non biologic treatment. These variables had to be completed in each biologic treatment change.

The adverse event variable was collected in 2 ways, using an open-ended question and using a term based on the nomenclature of the Medical Dictionary for Drug Regulatory Activities (MedDRA). In this BIOBADASER phase III the updating of MedDRA to version 19.0. took place. In the event of adverse events, the product lot was also recorded in keeping with the pharmacovigilance regulation (Royal Decree 577/2013, of 26th July, with which the pharmacovigilance of drugs for human usage is regulated). In this new phase the Orange algorithm for assessing causality of adverse event with biologic treatment was recorded.20


The number of patients included in BIOBADASER phase III in the first year of recruitment was 2664. Out of these patients, 1070 came from phase II of the registry (40.2% of patients), whilst 1594 patients (59.8%) were included for the first time in the study. Table 2 shows the sociodemographic characteristics and diagnoses of the patients included in the first year of the registry. The registry mainly comprises middle aged women over the age of 50 and with a median disease evolution of 8.1 years, with an interquartile range of 11.5 years, prior to beginning any of the treatments included in the study.

Phase III of the BIOBADASER registry has updated the project after 10 years, incorporating in this register data regarding biosimilars and synthetic drugs with identifiable target, dealing with new data protection laws and pharmacovigilence regulations and incorporating data on effectiveness using direct clinical activity assessment parameters. All of these changes are ample justification for the need for this new phase in the BIOBADASER registry, Table 5.

Despite all of these modifications, the main aim of BIOBADASER phase III continues to be data collection relating to the safety of these treatments in patients with rheumatic diseases. The limited scope in time and the strict inclusion and exclusion criteria of patients in clinical trials continues to be a justification for the existence of perspectives studies based on information collected through independent registers based on data from routine clinical practice. Since this is a prospective register based on clinical practice, BIOBADASER is able to become a tool for the detection and analysis of low incidence adverse events, which may be observed in the long term and in a larger patient population.

This new phase of BIOBADASER has strengthened the prospective nature of the study, following the trend of other national European and North American registries on biologics which establish periodical follow-up check-ups.21 ARTIS, BSRBR, BRASS, CORRONA, RABBIT, SCQM and VARA are European and North American registries which collect information on effectiveness in routine clinical practice. One of the main changes introduced into this new BIOBADASER phase is the aim of assessing effectiveness in clinical practice. Up until the beginning of this new phase, BIOBADASER was able to assess effectiveness indirectly through the subrogated variable of survival of the biologic drug. In this new phase, in addition to information on survival of the drug, clinical activity indications for RA (DAS28 VSG and DAS28 CRP), PA (DAS28 ESR and DAS28 CRP), AS (BASDAI, ASDAS-CRP) and SLE (SLEDAI) are collected.

Since its initiation and in particular during phase II, BIOBADASER has participated in international collaborative projects, supplying data together with other registries.22–25 On a national level, it has also carried out collaborations with the registries of other specialities.26 In these multi-registry projects, and particularly in collaborative projects with other countries, a lack of alignment has been detected in the definitions and parameters included in the different platforms, which frequently limits the potential of these collaborative tasks.15 The need has arisen to establish standardised definitions and a set of common variables to improve this situation. In the new BIOBADASER phase new variables have been introduced and the collection of others has been improved to foster collaborative projects with other databases. Changes introduced included the use of the Charslon index to record comorbidities, the administration route, dose, periodicity of administration of biologic drugs and dose of concomitant glucocorticoids.

With the intention of improving cooperation between registries, the BIOBADAMÉRICA Project was enhanced from SER. This is a collaborative project with scientific rheumatology societies from countries in Latin America which use the same platform and methodological design as BIOBADASER Phase III.27,28 Recently, phase III of the study was initiated in the registries of Mexico, Argentina, Uruguay, Paraguay and Colombia.

One of BIOBADASER's main strengths continues to be its capacity to recruit and to collect information. In the new phase III 1594 new patients joined the study.29 Participation from 35 centres throughout Spain has guaranteed extensive coverage of the reality of dealing with biologic drugs. The number of patients included in the study is expected to continue increasing in the future.


BIOBADASER has become an international reference in the generation of information on safety in the use of biologic therapy in rheumatic diseases. Phase III of the project incorporates as its aim assessment of the effectiveness and it reinforces the prospective nature of the registry. BIOBADASER phase III complies with the new legislation in pharmacovigilance and communication of adverse events and includes the new biosimilars and synthetic drugs with an identifiable target with an indication in the rheumatic diseases.
