WALTHAM, Mass., July 26, 2019 (GLOBE NEWSWIRE) -- Chiasma, Inc. CHMA, a clinical-stage biopharmaceutical company focused on improving the lives of patients with rare and serious chronic diseases, today announced the pricing of its previously announced underwritten public offering of 10,000,000 shares of its common stock at a price to the public of $5.50 per share, before deducting underwriting discounts and commissions and other offering expenses payable by Chiasma. In addition, Chiasma has granted the underwriters a 30-day option to purchase up to an additional 1,500,000 shares of its common stock at the public offering price, less underwriting discounts and commissions.
