Threshold (NASDAQ:THLD) lost almost 60% of its remaining value after reporting that glufosfamide did not meet its endpoint in a Phase III trial. The trial tested the drug in patients with metastatic pancreatic cancer who had failed an earlier round of Gemzar from Lilly (NYSE:LLY).

Threshold fell $2.06 to $1.53, a drop of 58%.

Optimer priced its IPO at $7, and it closed today at $9.75, after losing 25 cents. Par was off 93 cents at $23.93.

In animal studies, VX15 suppressed the autoimmune response and blocked damage to the central nervous system. The compound has also shown anti-angiogenesis properties, but Teva will have an option to co-develop VX15 after the Phase I trials for oncology. Teva will make an equity investment in Vaccinex, make an upfront and milestone payments, and pay royalties on any marketed drugs, though the exact amounts of each were not disclosed. Teva and Pan Atlantic Bank and Trust Limited, an existing investor, are the lead participants in a third financing round for Vaccinex, which is expected to raise more than $25 million.
Teva also published data showing that Copaxone, its existing MS drug, was effective in males who have primary progressive multiple sclerosis. The data are part of a post-hoc study, as Copaxone failed to meet its endpoint in the original trial.
