Clinical development expenses related to Androxal® increased by $3.1 million and $7.6 million for the three and six month periods ended June 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. Clinical development expenses related to Proellex® decreased by $189,000 and $216,000 for the three and six month periods ended June 30, 2013, respectively, due to the completion of the Phase 2 vaginal administration study for uterine fibroids. Payroll and benefits expenses increased by $514,000 and $864,000 for the three and six month periods ended June 30, 2013, respectively, as compared to the same periods in the prior year due to increased headcount in R&D employees.
