As for KaloBios, it appears that Shkreli wants to keep this business in operation.

KB003, or lenzilumab, is an anti-GM-CSF mAb that KaloBios is evaluating in oncology indications where GM-CSF may play a key role, such as chronic myelomonocytic leukemia (CMML).

The company has approximately $5 million in cash and will endeavor to file its quarterly results on Form 10-Q as soon as possible.

KaloBios is actually in the process of shuttering its operations and liquidating its assets.

Shkreli will work with the company’s senior management team to ensure the company’s continued operations.

“Our board of directors is prepared to entertain any constructive proposal, which we will act upon promptly”, said Ronald Martell, Executive Chairman of KaloBios. Now that Shkreli controls KaloBios, that study will move forward as planned, he said, expecting to begin enrollment this year. Simple, he needs a stock shell to take his new Turing Pharma company public.

The high value tech IPOs today were much flagged, not least as Square Inc (NYSE:SQ) and Match Group (NASDAQ:MTCH) are coming to the markets at a volatile time for offerings.
