December was a month of positive milestones for key companies in the OIS Index. On December 18, more than two months before its February 28 Prescription Drug User Fee Act (PDUFA) date, Aerie Pharmaceuticals announced Food and Drug Administration approval of Rhopressa (netarsudil ophthalmic solution 0.02%) for glaucoma and ocular hypertension. On December 19, three weeks before its January 12 PDUFA date, Spark Therapeutics announced FDA approval of Luxturna (voretigene neparvovec-rzyl) gene therapy for inherited retinal disease. Also in December, Glaukos Corp. announced the Premarket Approval (PMA) submission for the iStent inject stent for use during cataract surgery, and the beginning of the US Investigational Device Exemption (IDE) trial for the iStent SA stand-alone procedure.
Despite these positive developments, all three of these stocks traded lower during December, as did the OIS Index overall. In December, the OIS Index declined by 3%, compared with gains of 1.5% for the NASDAQ Biotechnology Index and 0.9% for the overall US stock market as measured by the Russell 3000 Index, and a 2.4% decline for a composite of US medical device stocks.
Among the 31 stocks in the OIS Index, declining stocks outnumbered advancing stocks 21 to 10 during the month.
The largest positive contributor to OIS Index performance in December was Ohr Pharmaceutical (+0.9% contribution to index performance, stock up 119%), following a 39% gain in November. The stock surged after publication of a report on Seeking Alpha touting the high potential of Ohr’s Squalamine for wet age-related macular degeneration.
The second-largest positive contributor to the OIS Index in December was Second Sight Medical Products (+0.6% contribution to index performance, stock up 55%). Another top performer during December, but with a smaller impact on the OIS Index due to lower weighting within the index, was Presbia (+41%). The move in Presbia’s stock followed a December 14 announcement of operational and management changes, along with a financing event.
The largest negative contributor to OIS Index performance in December was Spark Therapeutics (–2.4% contribution to index performance, stock down 30%). Disappointing Phase I/II clinical data for the company’s gene therapy candidate for hemophilia A overshadowed the positive news regarding FDA approval of Spark’s Luxturna.
ThromboGenics (–0.8% contribution to index performance, stock down 26.4%) declined following discontinuation, due to slow recruitment, of the Phase II CIRCLE study of ocriplasmin for non-proliferative diabetic retinopathy.
2017 Performance Review
Despite a positive absolute return for the OIS Index during 2017 (+5.6%), the index underperformed the overall US stock market (+18.9%) and the biotech and medical device sectors (+21.1% and +30.3%, respectively).
