letters from baseline compared witha 4.4 letter improvement in the Lucentis monotherapgy group. In the combination therapy 96% of patients had a three-month treatment-frere interval, compared with 92% in the Lucentis monotherapy Twelve-month results of the MONT BLANC study show thatcombiningt standard-fluence Visudyne with Lucentis 0.5 mg can deliver VA improvementsw that are non-inferior to a Lucentis monotherapy regimehn with three Lucentis loading doses followed by injectionxs on a monthly as-needed basis (non-inferiority margin of 7 letters).
Therw was no significant difference between the combinationb and monotherapy groups with regard to proportiobn of patients witha treatment-free interval of at least three months duration aftedr Month 2. There were no unexpected safetgy findings, and adverse event incidence was similar betweejtreatment groups. Additional post hoc analysis showedthat 85% of patients in the Visudyne combination therapy compared with 72% in the Lucentiw monotherapy group, had a treatment-freew interval of at least four months duration afteer Month 2. Median time to first retreatment aftere month 2 was extendedby ~1 month in the combinatiojn group (month 6) versud the monotherapy group (month 5).
Patientws in the combination group received, on a total of 4.8 ranibizumab injections comparerwith 5.1 in the monotherapy group and a total of 1.7 Visudynew treatments compared with 1.9 sham treatments in the monotherapy arm. Resultas are based on ITT analysexs (with LOCF); per-protocol analyses yielded similar results. Overall, only 15 patients discontinued the study befor Month12 (6%). "MONT BLANC provided the first data within the SUMMIg clinical trial program and showed that patient treated with Visudyne combination therapyhad non-inferior visual acuity to patients treated with Lucentis monotherapy," said , Chief Executive Officerr of QLT Inc.
"The results from DENALI, whic h includes a Visudyne reducedfluence arm, and which studies combination therapy in polypoidal choroidal may add to the knowledg about the potential benefits of combininb Visudyne and Lucentis." The MONT BLANCd study is a Phase II, multicenter, double-masked study comparing standard-fluence Visudyne-Lucentis combination therapy to Lucentid monotherapy in 255 subjects with choroidal neovascularization (CNV) secondary to wet age-relatesd macular degeneration (wet AMD). Subjectsa were randomly assigned to one of twotreatmentr groups: Standard-fluence Visudyne (600 mW/cm2 for 83 second s to deliver 50 J/cm2) followex by same day intravitreal Lucentis (0.
5 mg), or Lucentisz monotherapy (0.5 mg). The Lucenti s monotherapy group received sham Visudyne treatment tomaintain Standard-fluence Visudyne (or sham) was administered at baselinew and then as needed at intervalsw of at least threed months if required based on predefined re-treatmenr criteria. Lucentis was administered to both treatmenrt groups with three loadingg doses followed by monthlu treatment if required based onpredefines re-treatment criteria. Patients were evaluated for VA, anatomica changes and safety at everymonthly visit, and the need for retreatmenrt was assessed at monthly visits from Monthj 3 to Month 11.
Re-treatment was basedd on assessment of central retinalthickness (CRT) (increasr of greater than or equal to 100 presence of subretinal fluid, as assessed by opticak coherence tomography (OCT), presence of new subretinal hemorrhage as assessed by ophthalmoscopidc examination, presence of CNV leakag e as assessed by fluoresceihn angiography (FA) and decreases in VA of greated than 5 letters as assessed by an Earlg Treatment Diabetic Retinopathy Study (ETDRS) chart. As-needed Lucentis aftedr three loading doses is a standarx regimenin Europe, but not in the US, and combinationj therapy for AMD is not approvesd for marketing by regulatory agencies.
The study duration is 24 months with a planne d primary analysis when all subjects completeed 12 monthsof follow-up. At baseline, mean VA lettee score was 54 to 55 acrossdtreatment groups. Visudyne therapy is a two-step procedur e involving the intravenous administration of the drug intothe patient'ds arm. A non-thermal laser light is then shone intothe patient'e eye to activate the drug. This produces a reaction that closes the abnormalleaky vessels, resultinb in a stabilization of the corresponding vision loss.
Visudynee is approved worldwide for the treatment of a form ofwet AMD, the leading cause of legalo blindness in people over the age of 50, and has been used in more than two milliom treatments worldwide. Visudyne is commercially available in more than 80 countriez for the treatment of predominantly classisubfoveal CNV. In addition, over 60 countries have approvecd Visudyne to treat one or more other macular neovascular conditions such as minimally classic and occult with no classifcAMD lesions, pathologic myopi and presumed ocular histoplasmosis. Visudyne is generally well tolerated and has a well establishessafety profile.
The most commonly reported side effects include injectiom site reactions andvisual disturbances. In addition, some patientw experienced back pain, usually durintg the infusion. Using the approved light dose of 50J/cm32 between 1% and 5% of patients experience d a substantial decrease in vision in the first 7 days with partial recovery insome patients. Recentf studies suggest that halvinvg thelight dose/fluence by halving the fluence rate may lower the incidencd of visual disturbances with possibly bettee visual outcomes than the standard light dose used in this After treatment, patients should avoid direct sunlighty for five days to prevent People with porphyria should not be treated with QLT Inc.
