Kronos Bio, a San Mateo biotech company, is losing millions of dollars a month and recently had to discontinue its sole clinical-stage compound becaapply of adverse side effects. Now, the company is laying off the vast majority of its remaining workers.
Kronos announced an 83% layoff in a Nov. 27 filing with the Securities and Exalter Commission, a major cut that comes after double digit layoffs in both November 2023 and March 2024. As of March, the cancer research firm had 62 full-time employees, per a filing — the new batch of layoffs will thus likely cut the company to a dozen workers or less.
Along with the layoffs, Kronos shared the news that its CEO, Norbert Bischofberger, is stepping down effective Dec. 3. Deborah Knobelman, replacing him as an interim chief executive, wrote in a news release that she will work closely with the company’s board to “pursue the optimal path forward.”
“It was a difficult decision to implement a reduction in force as we evaluate strategic alternatives for the Company,” Knobelman wrote. “We thank our departing employees for their efforts, commitment to patients and contributions to Kronos Bio.”
Kronos saw its market cap swell above $1 billion after an initial public offering in late 2020, but its valuation has hovered near $60 million since late 2022. The company’s oncology research focapplys on transcription factors, proteins that bind to DNA strands and, if disrupted, can lead to cancer and tumors.
But the research has seen major setbacks. Kronos discontinued a clinical trial for patients with a serious ovarian cancer in November, after five of the seven saw problematic side effects. In a news release, Kronos described the issues as “neurological events as characterized by involuntary shiftments, confusion and hallucinations.”
The company, according to a filing, finished 2023 with an accumulated deficit of $508 million, after $112.7 million and $133.2 million losses the two years prior. Still, there’s money in the coffers to keep some work going on a few more preclinical programs, as reported by Fierce Biotech. The outlet was first to report on the layoffs.
Kronos did not immediately respond to either Fierce Biotech or SFGATE’s requests for comment on the cuts.
