Coherus Biosciences Shows Major Stock Gain Upon BLA Resubmission

When it received a June 2017 complete response letter from the Food and Drug Administration (FDA), the outlook for Coherus Biosciences was cloudy. Its lead product, a biosimilar for pegfilgrastim (CHS-1701), had been cited for the way the drug maker evaluated immunogenicity and for manufacturing plant issues. Upon receiving the news, it cut 30% of its workforce.

Furthermore, Coherus has had little luck in challenging the existing patents of originator products. It was denied inter partes review on a key patent held by Abbvie on Humira® as well as a patent on Enbrel® by Amgen.

Today, Coherus may be on the verge of a turnaround in fortunes

Armed with new immunogenicity data, Coherus resubmitted its 351(k) application with the FDA on May 3, and investors reacted strongly to its new prospects. The company’s stock price soared 17.3% for the dCoherus Biosciencesay, closing at $14.90. Its previous 52-week low was $8.05. Coherus is a U.S. manufacturer that is focused solely on biosimilar development (a “pure-play” biosimilar maker).

In the company’s announcement, Coherus reported that the new FDA application is “supported by similarity data from analytical, pharmacokinetic, pharmacodynamics, and immunogenicity studies comparing CHS-1701 and Neulasta and integrates new immunogenicity data obtained from using a more revised immunogenicity assay.” Mr. Lanfear said, “The CHS-1701 BLA resubmission marks a significant milestone in our ongoing transition to a commercial company as we tightly focus on execution of our strategic plan.”

In April, Coherus filed for a rehearing of the etanercept inter partes review.

Coherus originally filed its pegfilgrastim biosimilar application with the European Medicines Agency November 29, 2016. According to a report from early in 2018, Chief Executive Officer Denny Lanfear asserted that he hoped to receive EMA approval in the second half of 2018.
