PURPOSE:
RESULTS:
• 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
• As of April 2013, the LUMINOUS study had
successfully
recruited
over
10, 000 number
patientsofglobally.

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.
• Ranibizumab is approved in the UK for the treatment of neovascular (wet) agerelated 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

Characteristics

Age, (years), mean (SD)
• 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.

Percentage of patients
• 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 healthrelated 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).
N, total number of patients; n, number of patients within the group
• 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:
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
•
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.
