Comparison of antitumour efficacy of single and combined mAbs in the intraperitoneal tumour model

Injected mAbs	Medium survival in days	N° of tumour free animal at day 120 (%)
Anti-HLA-DR	> 120*	11/18	(61%)
Anti-CD5	81*	9/21	(43%)
Anti-CD71	56*	4/18	(22%)
Anti-HLA-DR + anti-CD5	> 120**	13/13	(100%)
Anti-CD71 +anti-CD5	> 120**	7/8	(88%)
Anti-CD71 + anti-HLA-DR	> 120	7/13	(54%)
Untreated animals	32	1/47	(2%)

*significantly different from irrelevant IgG injected control mice (p < 0.005)

**significantly different from both single antibody treatments (p < 0.05)
