Contrary to the strength in the broader market, biotech stocks ended the week ending April 9 lower. The weakness partly reflected a preference for risky bets at the expense of defensives such as healthcare stocks.

FDA news flow of the week was mostly bordering on the negative. ACADIA Pharmaceuticals Inc. (NASDAQ:ACAD) was handed down a complete response letter for its regulatory application seeking expansion of the label of its Nuplazid to include dementia-related psychosis.

The biggest headline of the week was a disclosure by FibroGen, Inc. (NASDAQ:FGEN) that it had fudged data for its anemia drug, which sent its shares down about 48% during the week.

Provention Bio, Inc. (NASDAQ:PRVB) shares came under pressure after it communicated a likely delay in the approval of its Type 1 diabetes treatment candidate teplizumab. The company also said the FDA is not convinced with the pharmacokinetic data from the bridging study of teplizumab that was done to establish its comparability with an existing product from Eli Lilly and Company (NYSE:LLY). Data from Lilly's product was submitted as part of the teplizumab biologic license application.

Two biopharma companies debuted on the Nasdaq following their initial public offerings, raising a combined $221.3 million.
