THE WOODLANDS, Texas, Nov. 7, 2013 (GLOBE NEWSWIRE) -- Repros Therapeutics Inc.^® (Nasdaq:RPRX) today announced financial results for the third quarter ended September 30, 2013.

Liquidity and Capital Resources

The Company had cash and cash equivalents of approximately $81.8 million as of September 30, 2013 as compared to $24.2 million as of December 31, 2012. On June 25, 2013, we completed a public offering of 4,312,500 shares of our common stock at a price per share of $19.00. Net proceeds to us, after deducting underwriter's fees and offering expenses, were approximately $76.8 million. Net cash of approximately $18.5 million and $8.1 million was used in operating activities during the nine month periods ended September 30, 2013 and 2012, respectively. The major use of cash for operating activities for the nine month period ended September 30, 2013 was to fund our clinical development programs and associated administrative costs. Cash used in investing activities during the nine month period ended September 30, 2013 was approximately $839,000 primarily for capitalized patent and patent application costs for Androxal® and Proellex®.  

Financial Results

Net loss for the three month period ended September 30, 2013, was ($6.0) million or ($0.26) per share as compared to a net loss of ($4.6) million or ($0.30) per share for the same period in 2012. The net loss for the nine month period ended September 30, 2013, was ($20.6) million or ($1.03) per share as compared to a net loss of ($10.1) million or ($0.69) per share for the same period in 2012. The increase in loss for both the three and nine month periods ended September 30, 2013 as compared to the same period in 2012 was primarily due to an increase in expenses related to the clinical development of Androxal®, an increase in salary expense due to increased headcount and increased costs associated with our patent portfolio.                

Research and development ("R&D") expenses increased 53% or approximately $1.7 million to $4.8 million for the three month period ended September 30, 2013 as compared to $3.1 million for the same period in the prior year and increased 153% or approximately $10.4 million to $17.1 million for the nine month period ended September 30, 2013 as compared to $6.8 million for the same period in the prior year. Clinical development expenses related to Androxal® increased by $774,000 and $8.3 million for the three and nine month periods ended September 30, 2013, respectively, as compared to the same periods in the prior year due to the ongoing Phase 3 studies in men with secondary hypogonadism, including two pivotal studies being conducted under an SPA, a six month open label safety study and a one year DEXA study. Payroll and benefits expenses increased by $515,000 and $1.4 million for the three and nine month periods ended September 30, 2013, respectively, as compared to the same periods in the prior year due to increased headcount in R&D employees. Operating and occupancy expenses increased by $333,000 and $825,000 for the three and nine month periods ended September 30, 2013, respectively, as compared to the same periods in the prior year due to an increase in costs associated with our patent portfolio, increased travel and professional services.

General and administrative ("G&A") expenses decreased 16% or approximately $238,000 to $1.2 million for the three month period ended September 30, 2013 as compared to $1.5 million for the same period in the prior year and increased 3% or approximately $105,000 to $3.5 million for the nine month period ended September 30, 2013 as compared to $3.3 million for the same period in the prior year. The decrease in G&A expenses for the three month period ended September 30, 2013 as compared to the same period in the prior year is primarily due to a decrease in non-cash stock based compensation, partially offset by an increase in professional services. The increase in G&A expenses for the nine month period ended September 30, 2013 as compared to the same period in the prior year is primarily due to an increase in professional services. 

Total revenues and other income increased to $3,000 for the three month period ended September 30, 2013 as compared to $1,000 for the same period in the prior year. Total revenue and other income was $6,000 for the nine month period ended September 30, 2013 as compared to $1,000 for the same period in the prior year. The increase for the three and nine month periods ended September 30, 2013 as compared to the same periods in the prior year was primarily due to increased cash balances as a result of the public offering completed June 25, 2013 for net proceeds of approximately $76.8 million.

As of September 30, 2013 we had 23,009,609 shares of common stock outstanding.
