Middleton, WI, January 26, 2005 – Bone Care International, Inc. (Nasdaq: BCII) today announced financial results for its second fiscal quarter and for the six months ended December 31, 2004. The company reported record quarterly sales for Hectorolâ (doxercalciferol) of $19.6 million, compared to $9.1 million for the second quarter of fiscal 2004, representing a 115 percent increase. The company achieved its fourth consecutive quarter of profitability with net income of $1.8 million, or $0.09 per diluted share, compared with a net loss of $478,000, or $0.03 per share, in the second quarter of fiscal 2004. For the six months ended December 31, 2004, Hectorolâ sales were $37.0 million, an increase of $19.7 million, or 114 percent, from the same period in 2004. Net income was $3.0 million, or $0.15 per diluted share, for the first six months of fiscal 2005, compared with a net loss of $2.6 million, or $0.18 per share, for the same period in fiscal 2004. The company ended the quarter with $118 million in cash and investments.

“Bone Care’s performance was strong in the second quarter,” said Paul L. Berns, President and Chief Executive Officer of Bone Care International. “We continued to advance our Hectorolâ brand as evidenced by the 115 percent and 114 percent revenue growth in the second quarter and for the first six months of fiscal 2005, respectively, compared to the same periods in fiscal 2004. Additionally, we achieved our seventh consecutive quarter of revenue growth as evidenced by a 13 percent increase in the second quarter of 2005 from the first quarter of 2005 and our fourth consecutive quarter of increasing profitability. These results have been achieved as we continued to invest in our research and development pipeline and planned expansion of our sales organization in the second fiscal quarter of 2005. This is a credit to sound fiscal management by our executive leadership team as well as the continued exceptional performance of our operating and sales teams.”

Gross margin on sales of Hectorolâ was 77 percent for the second quarter of fiscal 2005, compared with 75 percent for the same period in fiscal 2004, and 76 percent for the six months ended December 31, 2004, compared with 74 percent for the same period in fiscal 2004. The improvement in margins in the fiscal 2005 periods was due primarily to economies realized on higher sales volumes of Hectorolâ.

Research and development expense was $3.2 million in the second quarter, an increase of $1.4 million, or 78 percent, from the second quarter of fiscal 2004. For the six months ended December 31, 2004, research and development expense was $5.8 million, an increase of $2.0 million, or 51 percent, from the first six months of fiscal 2004. The majority of the increases in both the second quarter and first six months of fiscal 2005 were attributed to pre-clinical and clinical study activities.

Selling, general and administrative expense was $10.6 million in the second quarter, an increase of $5.1 million, or 91 percent, from the second quarter of fiscal 2004. For the six months ended December 31, 2004, selling, general and administrative expense was $20.5 million, an increase of $8.9 million, or 76 percent, from the first six months of fiscal 2004. The majority of the increases were attributed to a planned expansion in the sales organization in the second quarter of fiscal 2005, and marketing and co-promotion expenses related to sales of Hectorolâ 0.5 mcg Capsules for both the second quarter and first six months of fiscal 2005. Additionally, legal expense increased in the second quarter and in the first six months of fiscal 2005 due primarily to intellectual property and general legal activities.

“The excellent results achieved by our organization have allowed us to again increase our sales guidance for fiscal 2005,” said Mr. Berns. “The current sales guidance range is $75 million to $79 million which we are now revising to $77 million to $80 million for fiscal 2005.”

Additional highlights during the second quarter of fiscal 2005 included:

· Receipt of a notice of allowance from the U.S. Patent and Trademark Office for claims relating to stabilized Hydroxyvitamin D2 products and pharmaceutical compositions and medicaments including stabilized Hydroxyvitamin D2, strengthening the depth of the company’s intellectual property portfolio and extending the protected time horizon;
· Inclusion in the NASDAQ biotechnology index;
· Continued progress of the commercialization of Hectorolâ 0.5 mcg Capsules for the treatment of secondary hyperparathyroidism in pre-dialysis chronic kidney disease patients.
