Efficacy and safety of Afalaza in men with symptomatic benign prostatic hyperplasia at risk of progression: a multicenter, double-blind, placebo-controlled, randomized clinical trial.

introductionIn order to investigate the efficacy and safety of Afalaza in men with benign prostatic hyperplasia (BPH) at risk of progression, this multicenter, double-blind, placebo-controlled, randomized clinical trial was performed. Derived by technological treatment of antibodies to prostate-specific antigen (PSA) and endothelial nitric oxide synthase (eNOs), Afalaza was previously proved to modulate its molecular targets. The mechanism of action of the drug is associated with the modulating effect of the antibiodies (RA-Abs) on the molecular targets (PSA and eNOS) by way of conformational changes. MATERIAL AND

methodsA total of 49 patients aged 45-60 years with BPH and moderate lower urinary tract symptoms (LUTS), total prostate volume (TPV) ≥30 cm

resultsIPSS mean change was -3.7 ±3.0 (95% CI -4.3 to -3.2) after 12 months of Afalaza (vs. -2.9 ±2.4; 95% CI -3.3 to -2.4 in placebo; р = 0.02). Qmax growth was 2.5 ±4.3 ml/s (vs. 1.4 ±3.3 in placebo; p = 0.049), TPV reduced by 11.8 ±16.0% (vs. 6.5 ±14.7%; p = 0.01, and PSA remained unchanged. Afalaza therapy resulted in a significant decrease in the total sum of BPH progression symptoms (p = 0.01). The maximum effect of Afalaza was registered after 12 months without a tendency to form a 'plateau'. During the study, no patients experienced AUR or BPH-related surgery.

conclusionsA 12-month course of Afalaza therapy is effective and safe for patients with BPH. The results of end points measurements revealed asignificant advantage of Afalaza compared to placebo in the overall symptoms benefit and a decline in the risk of BPH progression.ClinicalTrials.gov: NCT01716104.
