Clinical data disappointments and third-quarte results cast a shadow on the BioWorld Neurological Diseases Index, closing November with an 18.37% year-to-date decline. This marks a slight improvement from its low point in October, down 23.79%, in contrast to the previous year’s upward trend, which it concluded with an 18.24% increase.

Approval of a new depression drug, stellar phase III data for both a schizophrenia therapy and an Alzheimer’s disease candidate, as well as an accelerated approval filing for a Duchenne muscular dystrophy gene therapy, are all reasons that BioWorld’s Neurological Diseases Index climbed from a negative position throughout much of 2022 to its 11% above-water mark as of Oct. 20.

As neurological disease stocks begin to move in the right direction, and a potential U.S. FDA approval nears for a major depressive disease drug, shares are still down by 11.68% this year. BioWorld’s Neurological Diseases Index is following a similar path as the Nasdaq Biotechnology Index (NBI), which hit bottom at the end of May and has begun to climb since then. Still, NBI is down 15.92% this year, while the Dow Jones Industrial Average is down 12.41%.

After hitting a low in late February, BioWorld’s Neurological Diseases Index is rebounding, although it is still down by 8.9% this year, following the same path of the broader markets.

While financings have reached record levels, the stocks of BioWorld’s Neurological Diseases Index are now underground by 12.5%, a trajectory shadowed by the Nasdaq Biotechnology Index, down by 3.45%. The Dow Jones Industrial Average representing the broader markets, however, is up by nearly 13%.

With new therapeutics under FDA review for migraine, Alzheimer’s disease and seizures, and several rare disease gene therapies in development, stocks included in BioWorld’s Neurological Diseases Index are tracking 6.09% ahead for the year.

Although 14 of the 17 stocks that make up BioWorld’s Neurological Disease Index (NDI) dropped in value over the last month, the index is still ahead by about 9% this year, with a huge surge by Prothena Corp. plc leading the way.

The significant risks and high costs associated with neurological R&D has tended to keep companies and investors on the sidelines over the past few years. However, thanks to research progress and the development of new technologies, business development and investing in the space is heating up once again.

Two complete response letters for group members dispatched this month by the FDA was enough to contribute to a flat performance in October for the BioWorld Neurological Diseases index. Overall, the price-weighted index has remained underwater for most of the year with its value down about 5% during this period.

In a relatively light news flow for the group last month, the gainers and decliners in the BioWorld Neurological Diseases index canceled themselves out during August, with the result that the price-weighted index closed relatively flat and, despite briefly moving into positive territory in July, its value is down 4% for the year.
