Palatin Technologies Reports Fiscal Year 2006 Second Quarter Results; Teleconference And Webcast Being Held Today At 10:00 A.M. EST

CRANBURY, N.J., Feb. 9 /PRNewswire-FirstCall/ -- Palatin Technologies, Inc. announced today financial results for the second quarter ended December 31, 2005. Total revenues in the quarter ended December 31, 2005 were $4.6 million, compared to $4.8 million for the same period in 2004. Palatin reported a net loss of $7.4 million, or ($0.13) per basic and diluted share, for the quarter ended December 31, 2005, compared to a net loss of $2.3 million, or ($0.04) per basic and diluted share, for the same period in 2004. At December 31, 2005, the Company had cash and investments totaling $19.1 million.

The increase in the net loss for the quarter ended December 31, 2005 versus the quarter ended December 31, 2004 was primarily attributable to increased research and development costs related to bremelanotide (formerly PT-141), a drug under development for the treatment of erectile dysfunction (ED) and female sexual dysfunction (FSD), and inventory write-downs associated with the suspension of sales and marketing activities related to NeutroSpec(R), a radiopharmaceutical imaging agent previously approved in the United States for the diagnosis of equivocal appendicitis. In addition, the quarter ended December 31, 2004 included product sales of $1.3 million on shipments of NeutroSpec by the Company to Tyco Healthcare Mallinckrodt, the Company’s strategic collaboration partner. There were no such shipments in the current period.

“We are proceeding as planned to advance the commercial development program for bremelanotide (formerly PT-141), with two ED and two FSD clinical trials currently ongoing, and expanding pre-clinical activities for our other product candidates,” said Stephen T. Wills, chief financial officer of Palatin. “Additionally we are reviewing the relationship between NeutroSpec and the reported serious adverse events, as well as plans for other indications, most notably being osteomyelitis, in preparation for an FDA Advisory Panel meeting later this year.”

PRODUCT REVENUE AND ROYALTIES

For the quarter ended December 31, 2005, royalty revenue on Mallinckrodt’s commercial sales of NeutroSpec amounted to $0.6 million, compared to $0.2 million in the quarter ended December 31, 2004. In the current period, the Company recorded no product sales revenue from shipments of NeutroSpec to Mallinckrodt, versus $1.3 million in the quarter ended December 31, 2004.

LICENSE, GRANTS AND CONTRACTS

In the quarter ended December 31, 2005, revenue from licenses, grants and contracts was $4.0 million, consisting of $3.9 million related to bremelanotide pursuant to the Company’s collaboration agreement with King Pharmaceuticals, and $0.1 million from Mallinckrodt related to NeutroSpec. In the quarter ended December 31, 2004, revenue from licenses, grants and contracts was $3.3 million, all related to bremelanotide.

COSTS AND EXPENSES

Total operating expenses for the quarter ended December 31, 2005 were $12.9 million, compared to $7.8 million for the same period in 2004. Included in the current period was $2.0 million of NeutroSpec inventory write-downs related to the Company’s decision in December 2005 to suspend sales and marketing activities. In addition, development costs related to bremelanotide increased by $1.6 million, reflecting costs associated with clinical trials that were initiated in the current fiscal year. Other research and development costs, including expenses of the Company’s MIDAS(TM) programs, also increased.

CASH POSITION

Palatin’s cash and investments totaled $19.1 million as of December 31, 2005, compared to $18.1 million at June 30, 2005. In September 2005, the Company received $10.0 million from the sale of common stock and warrants to King, pursuant to its collaboration agreement.
