  • PURPOSE:

  • Ranibizumab (Lucentis®) is a humanized monoclonal antibody Fab fragment, specifically designed for ocular use. It selectively binds to and inhibits multiple isoforms of vascular endothelial growth factor A (VEGF-A), with low systemic half-life (~2 hours)1

  • Ranibizumab is approved in the UK for the treatment of neovascular (wet) age-related macular degeneration (wAMD), visual impairment due to diabetic macular oedema (DMO), and visual impairment due to macular oedema secondary to retinal vein occlusion (RVO) 2

  • Although the efficacy and safety profile of ranibizumab (Lucentis®) has been well established in randomised controlled clinical trials, there is a need for long term safety and effectiveness data in the real world setting.

  • The LUMINOUS prospective study is a 5-year, global, observational study designed to evaluate long-term safety (particularly the incidence of infrequent and serious adverse events), effectiveness, treatment patterns and health-related quality of life outcomes in patients treated in routine clinical practice with ranibizumab 0.5 mg according to the label approved in the participating countries

  • The study aims to enroll 30,000 patients from approximately 500 sites in 36 countries worldwide from March 2011 to March 2015, with end of the study in March 2016 (Figure 1).

  • Here, we present the baseline characteristics of the first cohort of 690 UK wAMD patients recruited from March 2011 to February 2012

  • METHODS:

  • The LUMINOUS prospective study design is presented in Figure 2:

  • Patients

  • Inclusion criteria

  • Adult patients (≥18 years) who are currently being treated with (existing ranibizumab, ER) or initiating treatment (treatment naive, TN) ranibizumab for any approved indication included in the local product label

  • Patients who provided written informed consent

  • Exclusion criteria

  • Simultaneous participation in a study that includes administration of any investigational drug or procedure

  • Systemic or ocular treatment with any VEGF inhibitor other than ranibizumab, 90 days prior to study enrolment

  • Contraindications listed on the ranibizumab Summary of Product Characteristics

  • RESULTS:

  • As of April 2013, the LUMINOUS study had successfully recruited over 10, 000 patients globally. The UK is currently the highest global recruiter to the study with over 5600 patients recruited to the study. At the time of the first cohort baseline analyses, the UK was the second highest contributor of data, recruiting 690 of the 1877 wAMD patients included within the analyses. Table 1 shows the overall demographic characteristics for the UK patients.

  • At enrolment into the study, 44.1% of wAMD patients were treatment naive (TN), 55.5% were existing ranibizumab patients (ER) and 0.4% had received other ocular treatments prior to baseline. 4.1% of patients received bilateral treatment at baseline. The ocular characteristics of the primary treated eye are shown in Table 2.

  • CONCLUSIONS:

  • LUMINOUS is an on-going study, successfully enrolling patients worldwide. The UK is the current major contributor to the global total.

  • The overall baseline characteristics of the first cohort of enrolled wAMD patients from the UK should be representative of the scenario seen in routine clinical practice. Compared to pivotal studies e.g. ANCHOR, a higher percentage of patients were in the better visual strata. One fifth of all patients who had prior ranibizumab therapy before entering LUMINOUS had vision of 74L or better.

  • Forthcoming data from LUMINOUS will provide a valuable source of real world data.
