Annexon shares fall 33% after patients drop out of Huntington's trial; Two Chinese biotechs net modest financing rounds
Annexon has some disappointing news, and it is evident at the Nasdaq.
Annexon, which went public back in 2020, had its share price $ANNX tumble more than 30% down to $7.30 on Wednesday after several patients discontinued treatment in a Phase II clinical trial for Huntington’s disease.
The drug candidate, ANX005, is a C1q blocker that was being designed and tested to disrupt Huntington’s disease. And while Annexon claimed the drug had shown improvement in more than half of patients after six months, five patients withdrew from the treatment — three due to a drug-related adverse event, two of which were considered serious adverse events, including systemic lupus erythematosus and idiopathic pneumonitis. Annexon said that after post-study drug discontinuation, one patient had symptoms resolved and the other patient stabilized.
While no deaths were reported, Annexon confirmed that the trial remains ongoing and it expects to have full data by the end of Q2 this year.

Accro Bioscience announced yesterday that it has raised over $50 million in an oversubscribed Series B round. The financing was led by Hongtai Aplus, along with participation from South China Venture Capital, Shenzhen Capital Group, Suzhou Oriza Holdings and other unnamed investors.
The Chinese biotech, founded in 2017, started out with a Series A from Morningside Ventures and focuses its research on regulated cell death, leading to emphases on inflammatory and autoimmune diseases alongside cancer as its main indications.
Accro co-founder and CEO Xiaohu Zhang expressed optimism in a prepared statement, saying “we are very pleased with the support and confidence of our current and new investors.”
Atom Bioscience raises $45 million in Series C for hyperuricemia and gout clinical trial
Chinese inflammatory and metabolic disease biotech Atom Bioscience closed $45 million in a Series C round to push its lead candidate into Phase III.
The Series C, led by Xicheng Jinrui Equity Investment Fund and ShenZhen GTJA Investment Group, will push ABP-671 into a Phase III clinical trial for hyperuricemia and gout. Some of the raise will also go into preclinical and clinical development of other drugs in Atom’s pipeline.
This is Atom’s biggest cash infusion to date since its founding in 2012, and the round brings the biotech’s total financing to $87 million.
Aside from Atom’s lead candidate, the biotech has a candidate for NASH in preclinical studies alongside three candidates for gastric, colon and breast cancer.
Japanese biotech enters collaboration and licensing deal with Roche, Genentech
Japan peptide biotech PRISM BioLab announced in a statement last night that it has entered into a research collaboration and licensing agreement with Roche and Genentech.
While details on the deal are still somewhat scarce, PRISM will give Roche and Genentech access to its library of peptide mimetic small molecules for the biotechs to screen against specific targets. Upon identification of hit compounds, Roche and Genentech may elect to further develop and commercialize the compounds.
PRISM BioLab is eligible to receive an upfront payment, success-based milestone payments and royalties on future net sales, but those details remain out of view for now.
