TNP-470, an analogue of fumagillin, has been shown to inhibit angiogenesis in vitro and in vivo. In 1992, TNP-470 entered clinical development for cancer as an anti-angiogenic agent. It is currently in Phase I/II trials in Kaposi's sarcoma, renal cell carcinoma, brain cancer, breast cancer, cervical cancer and prostate cancer. In early clinical reports, TNP-470 is tolerated up to 177 mg/m(2) with neurotoxic effects (fatigue, vertigo, ataxia, and loss of concentration) being the principal dose limiting toxicity (DLT). Terminal half-life values are short and have shown intermittent and intrapatient variation (range: 0.05 - 1.07 h). Recently, mechanistic studies have identified cell cycle mediators and the protein methionine aminopeptidase-2 (MetAP-2) as molecular targets of TNP-470 and fumagillin. Animal studies confirm some toxic effects on normal angiogenic processes such as the female reproductive system and wound healing, which will require caution and close monitoring in the clinic. TNP-470 is one of the first anti-angiogenic compounds to enter clinical trials, making it a valuable prototype for future trials of angiogenesis inhibitors in oncology.

Objectives: To investigate (a) the magnitude and durability of symptom score reduction and HRQL score improvement (including sexual drive); (b) adverse outcomes; and (c) progression to acute urinary retention and prostate surgery up to three years of treatment with alfuzosin. Methods: Three thousand two hundred and twenty-eight BPH-patients out of 812 centers were included in a prospective three-year open-labelled study and treated with alfuzosin (immediate release formulation) at the recommended dosage. A symptom score (Boyarsky modified) and a 20-item BPH specific HRQL score including three questions of sexuality (Urolife(TM) BPH QoL 20) were self-administered at baseline, 3, 6, 12, 18, 24, 30, and 36 months. Results: Two thousand five hundred and seventy-nine patients (79.9%) completed the study at the end of three years. Symptom score was significantly reduced by 54% at 3 months and this reduction was maintained up to 36 months (-48.4%); HRQL score was significantly improved by 45.4% at 12 months and this improvement was maintained up to 36 months (+43.4%). Alfuzosin was well tolerated: the quantitative and qualitative distribution of adverse events was similar to that previously observed in placebo-controlled studies (vertigo/dizziness: 2.1%). Adverse events accounted for 4.2% of the drop-outs. 120 patients (3.7%) were operated on for BPH and nine patients (0.3%) experienced acute urinary retention. Conclusion: This medical outcomes study confirms the long-term safety profile of alfuzosin in the naturalistic conditions of general practice and highlights the need to measure HRQL in the context of patient's preferences.

Androgen deprivation therapy (ADT) for prostate cancer (PCa) causes bone loss. Although we reported previously that risedronate significantly recovers bone mineral density (BMD) for up to 12 months, there have been no reports with longer follow-up periods to date. This study extended our earlier series extending the follow-up period to 24 months. Eligible patients had histologically confirmed PCa without lumbar spine metastasis and underwent ADT. Lumbar spine BMD, urinary deoxypyridinoline (uDPD) and serum bone alkaline phosphatase were measured at 6, 12 and 24 months. Among the total of 96 patients, we analyzed 26 and 18 patients in risedronate administration and control groups, respectively. BMD relative to the young adult mean ratio, uDPD and serum bone alkaline phosphatase of the risedronate administration group recovered significantly after 24 months compared with the control group (P<0.0001, P=0.0001, and P<0.0001, respectively). Transient blurred vision, malaise and vertigo were observed in 1 patient each among the 46 patients treated with risedronate within 28 days after first administration. Oral administration of risedronate is safe and effective for the recovery of ADT-induced bone loss in PCa patients even at 24 months after commencement of treatment.
