Abstract
The effects and safety of loxiglumide, a cholecystokinin-A (CCK-A) receptor antagonist, on advanced pancreatic cancer were investigated in humans. A perspective, controlled (2.4 g/day vs. placebo), randomized, double-blind, parallel-group study was performed in 64 patients affected by nonresectable histologically diagnosed pancreatic cancer. The patients were stratified according to sex and stage (A, T3/N0-N1/M0; B, T1-T2-T3/N0-N1/M1; C, relapse after surgical exeresis). Tumor size (by computed tomography scan) and mortality rate were evaluated as efficacy criteria. Clinical symptoms and physical signs, laboratory tests, and adverse reactions were checked every 6 weeks as efficacy/tolerability criteria. Forty-two male and twenty-two female patients were considered. A homogeneous distribution of the patients was demonstrated in the two treatment groups. Group C was not statistically evaluated for survival and tumor evolution because of its small number. Three patients dropped out for causes not related to the therapy. No toxic reactions to the drug were reported. Tumor size monitoring within groups A and B demonstrated a similar increase in both the loxiglumide and the placebo group. Survival in group A was higher than in group B (p = 0.0003). In group B, survival was lower in females (F) than in males (M) (F = 61.00 +/- 6.47 days, M = 140.44 +/- 22.15 days; p = 0.012), while survival by sex was similar in group A and in global analysis. Survival by treatment was similar for groups A and B. Survival by surgery was higher (p = 0.049) for surgical palliation than for nonoperated patients. The tumor grade affected survival but it did not vary by therapy. In conclusion, sure efficacy of loxiglumide in advanced pancreatic cancer was not demonstrated by our results. In consideration of its documented tumor growth inhibiting action, we suggest that loxiglumide be tested for recurrence prevention after resective surgeryPubblicazioni consigliate
