Trial Outcomes & Findings for Treatment for Completers of the Study B7A-MC-MBCM (NCT NCT00266695)

This study, B7A-MC-MBDV (MBDV), was an open-label extension of Study B7A-MC-MBCM (MBCM; NCT00604383), and was only open to participants who completed Study MBCM. Unless otherwise stated, the time frames refer to this study, MBDV.

Treatment for Completers of the Study B7A-MC-MBCM

The number of participants who experienced SMVL in at least 1 diabetic retinopathy (DR) study eye. SMVL was a ≥15-letter decrease from baseline in best-corrected Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (VA) that was sustained for the last 6 months of the study. Best-corrected ETDRS VA was measured at 4 meters (m) using an eye chart with 5 letters per row of decreasing letter size in each successive row. Participants read the chart from the top down until reaching a row where ≥3 letters in the row could not be read correctly. If \<20 letters were read correctly at 4 m, the chart was re-read at 1 m. The best-corrected ETDRS VA score was the total number of letters read correctly per eye at 4 m, plus a correction factor of 30 if ≥20 letters were read correctly at 4 m, plus the total number of letters read correctly at 1 m, if assessed. Best-corrected ETDRS VA scores ranged from 0 (no letters read correctly) to 100 (all letters read correctly).

The number of participants whose best-corrected Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (VA) in at least 1 diabetic retinopathy (DR) study eye decreased by 15-letters or less from the conclusion of Study MBCM to the start of Study MBDV, 6 to 18 months later. Best-corrected ETDRS VA was measured at 4 meters (m) using an eye chart with 5 letters per row of decreasing letter size in each successive row. Participants read the chart from the top down until reaching a row where ≥3 letters in the row could not be read correctly. If \<20 letters were read correctly at 4 m, the chart was re-read at 1 m. The best-corrected ETDRS VA score was the total number of letters read correctly per eye at 4 m, plus a correction factor of 30 if ≥20 letters were read correctly at 4 m, plus the total number of letters read correctly at 1 m, if assessed. Best-corrected ETDRS VA scores ranged from 0 (no letters read correctly) to 100 (all letters read correctly).

The number of participants who experienced SMVL, long term, in at least 1 diabetic retinopathy (DR) study eye. Long term SMVL was a ≥15-letter decrease from Study MBCM baseline in best-corrected Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (VA) that was sustained for the last 6 months of Study MBDV. VA was measured at 4 meters (m) using an eye chart with 5 letters per row of decreasing letter size in each successive row. Participants read the chart from the top down until reaching a row where ≥3 letters in the row could not be read correctly. If \<20 letters were read correctly at 4 m, the chart was re-read at 1 m. The best-corrected ETDRS VA score was the total number of letters read correctly per eye at 4 m, plus a correction factor of 30 if ≥20 letters were read correctly at 4 m, plus the total number of letters read correctly at 1 m, if assessed. Best-corrected ETDRS VA scores ranged from 0 (no letters read correctly) to 100 (all letters read correctly).

An mSMVL event was defined as a ≥15-letter decrease from Study MBDV baseline in best-corrected Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (VA) during any 6-month period, not just the last 6 months of the study. An mSMVL event was the first occurrence of an mSMVL in a participant, and the time at which the mSMVL began was used as the time of the event for the analysis. VA was measured at 4 meters (m) using an eye chart with 5 letters per row. Participants read the chart from the top down until reaching a row where ≥3 letters in the row could not be read correctly. If \<20 letters were read correctly at 4 m, the chart was re-read at 1 m. The best-corrected ETDRS VA score was the total number of letters read correctly per eye at 4 m, plus a correction factor of 30 if ≥20 letters were read correctly at 4 m, plus the total number of letters read correctly at 1 m, if assessed.

Best-corrected ETDRS VA scores ranged from 0 (no letters read correctly) to 100 (all letters read correctly). A higher score represented better VA.
