Bluebird Bio Inc. became the latest in a spate of gene therapy firms to disclose restructuring plans, as the company aims to save $160 million over the next two years, saying goodbye to about a third of its workforce.

The company conference call related to Akebia Therapeutics Inc.’s complete response letter (CRL) for vadadustat, an HIF prolyl-hydroxylase inhibitor for anemia caused by chronic kidney disease, brought on the ongoing and perhaps inevitable comparisons with a similar product from Fibrogen Inc., rejected by the agency last August.
Opinion on Wall Street said the matter could have gone either way, but in the end Akebia Therapeutics Inc.’s vadadustat, a HIF prolyl-hydroxylase inhibitor for anemia caused by chronic kidney disease (CKD), garnered a complete response letter (CRL) instead of approval from the FDA. The news slammed Akebia shares (NASDAQ:AKBA), which closed at 82 cents, down $1.61, or 66%. Specifically, the agency said that the data in the NDA do not support a favorable benefit-risk assessment of vadadustat in dialysis-dependent (DD) and non-DDs patients.
Results from the phase IIb challenge study with its intranasal immunomodulator for influenza A, REVTx-99a, in healthy volunteers sent Revelation Biosciences Inc. shares (NASDAQ:REVB) into a tailspin, and the stock closed at $1.32, down 82 cents, or 38.3%.

Though conceptually understood for decades, antibody-drug conjugates (ADCs) haven’t begun to come into their own until recently, but oncology drug developers continue to wrestle with challenges, large among them the problem of antigen selection. Lately, companies including names such as Adagene Inc., Bioatla Inc. and Cytomx Therapeutics Inc., have taken particular interest in exploiting features of the cancer growth itself to add more oomph, with focus on special features of the tumor microenvironment (TME).
The beleaguered PI3K-delta inhibitor space took another blow after MEI Pharma Inc. and partner Kyowa Kirin Co. Ltd. said the U.S. FDA won’t greenlight zandelisib without data from a randomized study.
