Columbia Laboratories Reports Third Quarter 2005 Results; Net Revenues up 28%, Operating Expenses Down 41% from Prior Year Period.

LIVINGSTON, N.J. -- Columbia Laboratories, Inc. (NASDAQ: CBRX) today announced results for the third quarter ended September 30, 2005. Financial highlights of the quarter include:

--Net revenues of $6.5 million, a 28% increase from $5.1 in the third quarter of 2004, and a 3% increase from $6.3 million in the second quarter of 2005

--Operating expenses of $4.8 million, a 41% decrease from $8.1 million in the third quarter of 2004, and a 5% decrease from $5.0 million in the second quarter of 2005

--Loss from operations of $650,000, an improvement from loss from operations of $5.2 million in the third quarter of 2004, and from $959,000 in the second quarter of 2005

--Net loss of $1.3 million, an improvement from net loss of $6.0 million in the third quarter of 2004, and from $1.6 million in the second quarter of 2005

--Net loss per basic and diluted share of $0.03, an improvement from a net loss per basic and diluted share of $0.14 in the third quarter of 2004, and from a net loss per basic and diluted share of $0.04 in the second quarter of 2005

"The successful implementation of operational efficiencies positively impacted our financial results," stated Fred Wilkinson, Columbia's president and chief executive officer. "For the past three quarters we have consistently increased revenues and decreased operating expenses, both of which are in line with our expectations for year end 2005."

Recent operational highlights include:

--Continued improvement in enrollment in the Prochieve(R) preterm study, albeit at a slower than anticipated rate

--Successful completion of a pharmacokinetics study for lidocaine vaginal gel for the prevention and treatment of dysmenorrhea

--Two new independent directors elected to the Company's board

During the third quarter, Columbia implemented new strategies to accelerate recruiting and enrollment of patients in its Prochieve(R) preterm study, which is designed to show the effect of Prochieve(R) 8% in reducing the incidence of preterm delivery in women who are predisposed to this problem. Fifteen additional study centers were added during the past three months bringing the total number of centers to 48. The Company also supports the study centers through a publicity campaign that includes the distribution of a video news release (VNR) about the study and preterm birth, local television and radio advertising, telemarketing to referral physicians, national advertising on the Discovery Health cable network, newspaper and journal advertising, and Internet links to the study web page. This publicity campaign, coupled with the increase in the number of study centers, helped Columbia achieve the highest monthly patient enrollments to date in September, and again in October.

Columbia now anticipates that, as a result of the publicity campaign and other support activities, enrollment in the preterm study will continue to accelerate and will be completed by the end of first quarter, 2006. However, should the Company experience additional delays in recruiting at some of the new study centers, continued reluctance of some obstetricians to refer their patients, and lower than anticipated willingness by eligible patients to enroll in a placebo-controlled study, completion of enrollment could extend beyond the first quarter. The Company now expects, if positive results are obtained, to file with the FDA for a label indication in the second half of 2006. Columbia continues to evaluate the possibility of conducting an interim analysis of the study, which could permit the Company to complete the trial with fewer patients and on an earlier timeframe.

Columbia recently announced the successful completion of a pharmacokinetics study for its lidocaine vaginal gel for the prevention and treatment of dysmenorrhea and pelvic pain. The study evaluated both the blood levels obtained by, as well as the relative safety from, three doses of lidocaine formulated with Columbia's patented bioadhesive vaginal gel. Based on those results a Phase II study is scheduled to start in the fourth quarter of 2005.

Also, Columbia recently strengthened its Board of Directors through the election of Valerie L. Andrews and James S. Crofton. Both are independent directors and bring to seven the number of independent directors on the Company's eight-person Board.

Financial Overview

Net revenues for the third quarter of 2005 were $6.5 million, up from $5.1 million in the third quarter of 2004. Net revenues for the first and second quarters of 2005 were $4.3 million and $6.3 million, respectively. Net revenues from Promoted Products were $2.3 million in the third quarter of 2005 as compared with $3.6 million in the third quarter of 2004, primarily as a result of lower purchases of both Striant(R) and the Prochieve(R) line of products by trade customers. Net revenues from Partnered Products were $4.2 million in the third quarter of 2005 as compared with $1.5 million in the third quarter of 2004, primarily due to an increase in the sale of RepHresh(R) and Crinone(R) to our marketing partners.

Gross profit as a percentage of net sales was 63% in the third quarter of 2005, versus 57% in the third quarter of 2004. The higher percentage resulted from an increase in overall production and a change in product mix in the third quarter of 2005. The gross profit margins in the first and second quarters of 2005 were 58% and 65%, respectively.

Selling and distribution expenses were $1.7 million in the third quarter of 2005, a 67% decrease from $5.2 million in the third quarter of 2004, reflecting decreased sales force costs for promotion of the Company's products in the United States which resulted from the February 2005 sales force and marketing restructuring and concurrent reduction of the sales force from approximately 80 persons in the third quarter of 2004 to approximately 28 persons in the third quarter of 2005. Selling and distribution expenses for the first and second quarters of 2005 were $2.9 million and $2.1 million, respectively.

General and administration costs decreased 14% to $1.6 million in the third quarter of 2005 from $1.9 million a year ago. The reduction in expenses was primarily the result of a decrease in insurance premiums. General and administrative costs for the first and second quarters of 2005 were $1.8 million and $1.7 million, respectively.

Research and development costs were $1.5 million in the third quarter of 2005, a 43% increase from $1.0 million in third quarter of 2004. The increase is primarily related to an increase in the on-going Phase III trial for Prochieve(R) 8% in preventing preterm delivery in pregnant women who are at high risk. These increased costs were offset by a reduction in the costs of outside consultants.

As a result, for the third quarter of 2005 the Company reported a net loss of $1.3 million, or $0.03 per basic and diluted share, as compared to a net loss of $6.0 million, or $0.14 per basic and diluted share, in the third quarter of 2004.

As of September 30, 2005, Columbia had cash and cash equivalents of $7.2 million.

Outlook

The third quarter net loss from operations of $650,000 and the first nine months net loss from operations of $5.2 million are in line with the Company's previously projected net loss from operations of between $3.0 million and $6.0 million for fiscal year 2005. Third quarter net revenues of $6.5 million and the first nine months net revenues of $17.1 million are also in line with the Company's previously projected revenue range of $22 million to $28 million for fiscal year 2005.

With respect to fiscal year 2005, the Company is now narrowing its anticipated revenue range to between $22 million and $25 million and its net loss from operations range to between $5.0 million and $6.0 million. The Company now anticipates revenues from Partnered Products in the range of $15 to $16 million, and revenue from Promoted Products in the range of $7 to $9 million, for fiscal year 2005.

About Prochieve(R) 8% (progesterone gel) and Preterm Delivery

The Company is conducting a multi-center, randomized, double-blinded, placebo-controlled Phase III clinical study designed to assess the efficacy, safety, and tolerability of Prochieve(R) 8% (progesterone gel) in preventing preterm delivery in pregnant women who are at increased risk for preterm delivery. The study protocol defines 'at risk' patients as those with a history of a spontaneous preterm delivery or a cervical length of less than or equal to 2.5 cm (as measured by transvaginal ultrasound) with the current pregnancy. Under the study protocol, patients are treated with either Prochieve 8% or placebo for approximately seventeen weeks, or until delivery. Treatment is initiated between 18 and 22 weeks gestation. The primary endpoint is time to delivery.

The Prochieve study is designed to enroll 636 patients, and is currently enrolling patients at 48 study centers worldwide. Please visit www.PretermDeliveryTrial.com for additional information or to see if you may be eligible to participate in this study. Pregnant women who have had a prior preterm birth and who may wish to participate in the study, but who do not have Internet access, may contact Columbia Laboratories toll-free at 866-566-5636.
