NICE publishes new draft guidance on ranibizumab

for diabetic macular oedema after rapid review

Draft guidance from NICE has recommended ranibizumab as an option for treating visual

impairment caused by diabetic macular oedema (DMO). NICE conducted a rapid review of the

original guidance, published in November 2011, because the manufacturer submitted a revised

Patient Access Scheme, together with updated analyses including the drug's superior relative

effect among a sub-group of people with DMO.

The appraisal consultation document (ACD) makes the following recommendations:

1. Ranibizumab is recommended as an option for treating visual impairment due to diabetic

macular oedema only if:

the person has a central retinal thickness of 400 micrometres or more and

the manufacturer provides ranibizumab with the discount agreed as part of the patient access

scheme (as revised in 2012).

2. People currently receiving ranibizumab who do not have a central retinal thickness of 400

micrometres or more should be able to continue treatment until they and their clinician consider it

appropriate to stop.

In the press release, the Health Technology Evaluation Centre Director at NICE said: "Our current

guidance on the use of ranibizumab for treating visual impairment caused by diabetic macular

oedema, published in November 2011, does not recommend the drug as an effective use of NHS

resources. However, following the submission of a revised patient access scheme, we have

conducted a rapid review of the original guidance. The manufacturer included updated analyses

showing that ranibizumab could be expected to have a superior relative effect among people with

central retinal thickness greater than 400 micrometres. This draft guidance recommending

ranibizumab for some patients with diabetic macular oedema is now available for consultation."

Long term safety of ranibizumab in neovascular

age-related macular degeneration: SECURE Study

Abstract:

Participants

Two hundred thirty-four patients previously treated with ranibizumab for 12 months in the EXCITE/

SUSTAIN study.

Methods

Ranibizumab 0.5 mg administered at the investigator's discretion as per the European summary of

product characteristics 2007 (SmPC, i.e., ranibizumab was administered if a patient experienced a

best-corrected visual acuity [BCVA] loss of >5 Early Treatment Diabetic Retinopathy Study letters

measured against the highest visual acuity [VA] value obtained in SECURE or previous studies

[EXCITE and SUSTAIN], attributable to the presence or progression of active nAMD in the

investigator's opinion).

Main Outcome Measures

Incidence of ocular or nonocular adverse events (AEs) and serious AEs, mean change in BCVA

from baseline over time, and the number of injections.

(continued over page)


Results

Of 234 enrolled patients, 210 (89.7%) completed the study. Patients received 6.1 (mean) ranibizumab injections over 24 months.

Approximately 42% of patients had 7 or more visits at which ranibizumab was not administered, although they had experienced a

VA loss of more than 5 letters, indicating either an undertreatment or that factors other than VA loss were considered for

retreatment decision by the investigator. The most frequent ocular AEs (study eye) were retinal hemorrhage (12.8%; 1 event

related to study drug), cataract (11.5%; 1 event related to treatment procedure), and increased intraocular pressure (6.4%; 1

event related to study drug). Cataract reported as serious due to hospitalization for cataract surgery occurred in 2.6% of patients;

none was suspected to be related to study drug or procedure. Main nonocular AEs were hypertension and nasopharyngitis (9.0%

each). Arterial thromboembolic events were reported in 5.6% of the patients. Five (2.1%) deaths occurred during the study, none

related to the study drug or procedure. At month 24, mean BCVA declined by 4.3 letters from the SECURE baseline.

Conclusions

The SECURE study showed that ranibizumab administered as per a VA-guided flexible dosing regimen recommended in the

European ranibizumab SmPC at the investigator's discretion was well tolerated over 2 years. No new safety signals were

identified in patients who received ranibizumab for a total of 3 years. On average, patients lost BCVA from the SECURE study

baseline, which may be the result of disease progression or possible undertreatment.

Intravitreal aflibercept (VEGF Trap-Eye) in wet age-related macular

degeneration

Reference: Ophthalmology, published early online on 17 October 2012

Abstract:

Objective

Two similarly designed, phase-3 studies (VEGF Trap-Eye: Investigation of Efficacy and Safety in Wet AMD [VIEW 1, VIEW 2]) of

neovascular age-related macular degeneration (AMD) compared monthly and every-2-month dosing of intravitreal aflibercept

injection (VEGF Trap-Eye; Regeneron, Tarrytown, NY, and Bayer HealthCare, Berlin, Germany) with monthly ranibizumab.

Design

Double-masked, multicenter, parallel-group, active-controlled, randomized trials.

Participants

Patients (n = 2419) with active, subfoveal, choroidal neovascularization (CNV) lesions (or juxtafoveal lesions with leakage

affecting the fovea) secondary to AMD.

Intervention

Patients were randomized to intravitreal aflibercept 0.5 mg monthly (0.5q4), 2 mg monthly (2q4), 2 mg every 2 months after 3

initial monthly doses (2q8), or ranibizumab 0.5 mg monthly (Rq4).

Main Outcome Measures

The primary end point was noninferiority (margin of 10%) of the aflibercept regimens to ranibizumab in the proportion of patients

maintaining vision at week 52 (losing


FDA approves 'first nonsurgical

treatment' for

vitreomacular adhesion

The US Food and Drug Administration (FDA) reports the

approval of ocriplasmin for the treatment of symptomatic

vitreomacular adhesion (VMA).

The safety and efficacy of the drug have been previously

assessed in two randomized controlled trials published in the

New England Journal of Medicine, which involved over 600

patients with the condition, and showed a significantly higher

rate of VMA resolution after ocriplasmin versus placebo.

(abstract to this trial was referred to in August’s Newsletter)

Link to abstract

Edward Cox, director of the Office of Antimicrobial Products

in the FDA’s Centre for Drug Evaluation and Research said,

"Today's approval represents a significant advancement in

treatment for patients with symptomatic VMA. Those with

this sight-threatening disease now have a non-surgical

treatment option."

"Ocriplasmin is a recombinant protease with activity against

fibronectin and laminin, components of the vitreoretinal

interface," explain Julia Haller (Willis Eye Institute,

Philadelphia, Pennsylvania) and colleagues, authors of the

clinical trials.

The alternative treatment for VMA is vitrectomy, notes the

FDA statement, a surgical procedure that involves cutting

the vitreous gel in the eye and sucking it out.

In Haller et al's study, vitreomacular adhesion resolved in

26.5% of 464 VMA patients treated with a single injection of

ocriplasmin, compared with 10.1% of 188 placebo-injected

patients. In addition, the research team found that total

posterior vitreous detachment was significantly more

frequent among patients who had received ocriplasmin than

those who had received placebo, at 13.4% versus 3.7%.

However, the researchers report a higher rate of ocular

adverse events in ocriplasmin-treated eyes over the 6-month

follow-up period, including vitreous floaters, photopsia

(flashes of light), injection-related eye pain, blurred or

unclear vision, and conjunctival bleeding. Despite this, the

rate of serious adverse events was similar in both groups.

"Intravitreal injection of ocriplasmin was superior to injection

of placebo in altering the vitreoretinal interface of affected

eyes, although it was accompanied by some, mainly

transient, ocular adverse events," conclude Haller and coinvestigators.

PPV safe for irradiated uveal

melanoma

Ophthalmology Times Europe…...

Pars plana vitrectomy is safe to use on patients with plaqueirradiated

uveal melanoma, according to a study in the

Archives of Ophthalmology.

The retrospective case series, headed by Dr Alok S. Bansal,

Department of Immunology, St Helier Hospital, Carshalton,

Surrey, UK, included 47 eyes of 47 patients with plaqueirradiated

posterior uveal melanoma who underwent PPV for

vitreous haemorrhage.

The primary outcome measures included rates of intraocular

melanoma dissemination, extrascleral extension of

melanoma, local melanoma recurrence and systemic

melanoma metastasis after PPV.

No cases of intraocular melanoma dissemination or

extrascleral extension of melanoma were found. Local

choroidal melanoma recurrence was found in one patient

and was successfully managed with transpupillary

thermotherapy.

After a mean interval of five years after plaque radiotherapy,

four patients experienced systemic melanoma metastasis.

The management of vitreous haemorrhage using PPV is

safe and doesn’t increase the risk of intraocular, local, orbital

or systemic dissemination of the tumour in patients with

uveal melanoma
