1 Exhibit 21 [CELTRIX LETTERHEAD] NEWS RELEASE CONTACT: Andreas Sommer, Ph.D. President and Chief Executive Officer (408) 988-2500 CELTRIX REPORTS SECOND QUARTER RESULTS SANTA CLARA, CA -- October 23, 1997 -- For the second quarter ended September 30, 1997, Celtrix Pharmaceuticals, Inc. (Nasdaq: CTRX) reported revenues of $55,000 and a net loss of $3,213,000, or $.15 per share. In comparison, revenues were $37,000 and the net loss was $3,472,000, or $.23 per share, for the same period in 1996. Operating expenses decreased to $3,460,000 for the second quarter, from $3,644,000 for the same period last year. For the first six months ended September 30, 1997, revenues were $79,000 and the net loss was $5,781,000, or $.28 per share. This includes a $737,000 gain on investment during the first fiscal quarter from the sale of securities held by the company in Prograft Medical, Inc. For the same period last year, revenues were $79,000, and the net loss was $6,415,000, or $.42 per share. The decrease in net loss per share for both the second quarter and six months ended September 30, 1997, compared with the same periods in 1996, is due primarily to an increase in shares outstanding resulting from the company's April 1997 financing. At September 30, 1997, Celtrix had $13,374,000 million in cash, cash equivalents and short-term investments. "These financial results are in line with management's expectations," said Andreas Sommer, Ph.D., Celtrix's president and chief executive officer. "Our focus has been on the development of SomatoKine(R) therapy for a variety of serious medical conditions, and we have been actively engaged in human clinical studies." "Our Phase II clinical feasibility studies are progressing for two treatment indications, hip fracture surgery in the elderly and severe burns," Dr. Sommer said. "For hip fracture surgery, we are administering SomatoKine over a period of eight weeks to investigate the ability of this novel therapy to stimulate the formation of new muscle and bone, restore mobility and increase the patient's functional independence. For severe burns, we are administering short-term SomatoKine therapy to investigate its ability to speed the patient's recovery time and shorten the hospital stay. Clinical findings will guide expansion into full Phase II studies." Celtrix is a biopharmaceutical company developing novel therapeutics for the treatment of seriously debilitating, degenerative conditions primarily associated with severe trauma, chronic diseases or aging. The company's development focus is on SomatoKine, a novel IGF-BP3 complex, for use in regenerating lost muscle, bone and other tissues essential for the patient's health and quality of life. Initial product development programs target acute traumatic injury, such as hip fracture surgery in the elderly and severe burns. Other potential indications include severe osteoporosis and protein wasting diseases associated with cancer, AIDS and other life-threatening conditions. Through strategic alliances with Celtrix, The Green Cross Corporation is developing SomatoKine for the treatment of osteoporosis in Japan, and Genzyme Corporation is developing TGF-beta-2 as part of a comprehensive approach to tissue repair and the treatment of systemic disease. -more- 2 "Celtrix Reports Second Quarter Results" Page 2 This news release contains certain forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended.
