Pixantrone dimaleate versus other chemotherapeutic agents as a single-agent salvage treatment in patients with relapsed or refractory aggressive non-Hodgkin lymphoma: a phase 3, multicentre, open-label, randomised trial.

Background: Pixantrone dimaleate (pixantrone)--a novel aza-anthracenedione--was synthesised to reduce anthracycline-related cardiotoxicity without compromising antitumour efficacy. We aimed to assess the efficacy and safety of pixantrone versus an investigator's choice of a single-agent therapy in heavily pretreated patients with relapsed or refractory aggressive non-Hodgkin lymphoma.

Methods: In this phase 3, multicentre, open-label, randomised trial at 66 hospitals in Europe, India, Russia, South America, the UK, and the USA, patients with histologically confirmed aggressive non-Hodgkin lymphoma who had relapsed after two or more previous chemotherapy regimens were randomly assigned (1:1) by an interactive voice response system to treatment with pixantrone dimaleate (85 mg/m(2) intravenously on days 1, 8, and 15 of a 28-day cycle, for up to six cycles) or to a comparator (vinorelbine, oxaliplatin, ifosfamide, etoposide, mitoxantrone, or gemcitabine) given at prespecified standard doses and schedules.

Pixantrone dimaleate in combination with fludarabine, dexamethasone, and rituximab in patients with relapsed or refractory indolent non-Hodgkin lymphoma: phase 1 study with a dose-expansion cohort.

Background: Pixantrone dimaleate (pixantrone) has been shown to have antitumor activity in leukemia and lymphoma in vitro models and to lack delayed cardiotoxicity associated with mitoxantrone in animal models. FND-R, a combination regimen of fludarabine, mitoxantrone, dexamethasone, and rituximab, has been shown to be an effective regimen for low-grade lymphomas.

Methods: This dose-escalation study, with an expansion cohort, was conducted to evaluate the safety and preliminary efficacy of FPD-R, in which pixantrone was substituted for mitoxantrone in the FND-R regimen, in patients with relapsed or refractory indolent non-Hodgkin lymphoma (NHL).

Efficacy and safety of two dosing regimens of tadalafil and patterns of sexual activity in men with diabetes mellitus and erectile dysfunction: Scheduled use vs. on-demand regimen evaluation (SURE) study in 14 European countries.

Aim: The aim of this article is to evaluate the efficacy and safety of 20-mg tadalafil taken on demand or three times per week and its effect on the sexual activity of patients with diabetes mellitus and erectile dysfunction (ED).

Methods: The scheduled use vs. on-demand regimen evaluation (SURE) was a randomized, crossover, open-label study with 4,262 patients in 14 European countries.

Efficacy, safety, and treatment satisfaction of tadalafil versus placebo in patients with erectile dysfunction evaluated at tertiary-care academic centers.

Objectives: To determine the efficacy, safety, and treatment satisfaction of tadalafil 20 mg for erectile dysfunction (ED) in patients evaluated at tertiary-care academic centers.

Methods: In this randomized, double-blind, placebo-controlled trial, patients were randomly allocated to receive fixed-dose tadalafil 20 mg (n = 146) or placebo (n = 49) for 12 weeks. Efficacy was assessed by the International Index of Erectile Function (IIEF), Sexual Encounter Profile (SEP), and Global Assessment Question (GAQ); patient and partner treatment satisfaction by the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) and SEP; and safety by adverse events, laboratory values, and vital signs.
