0?mg/dL or ��12.0?mg/dL), history of diseases that influence Fluvoxamine bone metabolism (e.g., Paget's disease, primary hyperparathyroidism), or osteoporosis (T-score��?2.5) requiring antiresorptive therapy. Exclusions specific to women included breastfeeding, pregnancy, or failure to use at least one medically acceptable contraception method. The primary endpoint of this trial was the course of changes in bone turnover marker levels (CTX, P1NP, RANKL, OPG) during and after ZOL therapy. Secondary endpoints included pain (VAS and analgesic scores), rate of SREs (excluding hypocalcemia), PSA course (PC cohort), QoL, safety, tolerability, and potential relationships between baseline bone marker levels and clinical disease parameters (extent of disease, pain, and SREs). Analyses of these data were exploratory (i.e., hypothesis generating rather than hypothesis confirming). Summary statistics (intent-to-treat [ITT] and per-protocol populations) for absolute values and changes from baseline were calculated by visit and tumor type. Data were transformed using natural log (original value +1) to adjust for skewed distributions. Time-to-event variables (time to first SRE and overall survival) were analyzed using the Kaplan�CMeier method. All P values were calculated at a 5% significance level (two-sided). Appropriate two-sided 95% confidence intervals were calculated for means and proportions (Clopper and Pearson method). Missing values were replaced by the last observation carried forward. Safety assessments were based on frequency and type of adverse events (AEs) and changes in laboratory values. Patients with PC (n=301) or BC (n=99) were enrolled at 98 German sites between May 2006 I-BET-762 price and July 2008. Of the 400 treated patients, 335 completed the study ( Fig. 2). A total of 65 patients discontinued the study because of death (n=17), withdrawn consent (n=15), AEs (n=11), protocol violations (n=9), or other reasons (n=13). The entire ITT population (n=397) was analyzed and is composed of patients who received at least one ZOL dose and had one postbaseline bone marker assessment. Furthermore, within the ITT population, 276 patients were Pazopanib in vitro treated per protocol (i.e., had no major protocol violations). Two patients were excluded for bisphosphonate use within 6 months before study entry (1 ZOL and 1 clodronate). Baseline patient demographics and disease characteristics are summarized in Table 1. Notably, at study entry 27 patients had experienced 30 SREs (PC: 15 patients with 17 SREs; BC: 12 patients with 13 SREs), and baseline serum CTX and P1NP levels were higher in patients with PC versus BC. Study-end (120-day) visit data were available for 94% (n=372) of the ITT population (n=397) and 96% (n=266) of the per-protocol population (n=276). Therapy with ZOL decreased P1NP and CTX levels in 79% of patients (Table 2), and these reductions were significant (30 days, 60 days, or 90 days versus baseline; P
