The financing supports manufacturing, nonclinical and regulatory work on an oral candidate for dry mouth, alongside research-team expansion.

SiccaNova Therapeutics completed a ¥1.25 billion Series A announced on September 3. Recorded participants include Tohoku University Venture Partners, JIC Venture Growth Investments, WPower Fund I, Red Capital, Shichiju Shichu Capital and Joyo Capital Partners.
