Ohr Pharmaceutical reported topline data from the MAKO study, which did not meet its primary efficacy endpoint. The MAKO study evaluated the efficacy and safety of topically administered squalamine in combination with monthly Lucentis injections for the treatment of wet age-related macular degeneration. The primary efficacy endpoint was the mean visual acuity gain at 9 months, using a mixed-effects model for repeated measures (MMRM) analysis. Subjects receiving squalamine combination therapy (n=119) achieved a mean gain of 8.33 letters from baseline versus 10.58 letters from baseline with Lucentis monotherapy (n=118). There were no differences in the safety profile between the two treatment groups.

“We are very disappointed with the outcome of the MAKO study,” Jason Slakter, MD, chief executive officer of Ohr, said in a company news release. “We are grateful to the patients and physicians who participated in the clinical trial. Based on these results, we intend to evaluate strategic alternatives to maximize shareholder value.”

The MAKO study was a multicenter, randomized, double-masked, placebo-controlled clinical trial to evaluate the efficacy and safety of squalamine combination therapy for the treatment of wet-AMD. Subjects were randomized 1:1 to receive topical squalamine lactate ophthalmic solution, 0.2%, twice daily and monthly Lucentis injections (BID), or topical placebo BID and monthly Lucentis injections. Eligibility criteria for the study eye included: newly diagnosed with wet-AMD and no previous treatment, occult neovascularization, if present, measured less than 10mm2 as assessed by fluorescein angiography, and visual acuity between 20/40 and 20/320. A total of 237 subjects were randomized. Visual acuity was measured monthly using the Early Treatment of Diabetic Retinopathy Study (ETDRS) eye chart. The primary efficacy endpoint was the mean visual acuity gain at nine months, using a mixed-effects model for repeated measures (MMRM) analysis.
