Racotumomab induces a specific humoral and cellular immune response against the NeuGcGM3 ganglioside present in tumor cells, stimulating the cell death[4].
Racotumomab (50 μg/dose, i.p.) together with Keyhole limpet hemocyanin (KLH) inhibits tumor growth in F3II cell (s.c.) mammary tumor mice model[2].
Racotumomab (50 μg/dose, s.c.) together with Pemetrexed (100 mg/kg) is highly effective against lung nodules in 3LL cell (s.c.) mice xenograft[3].
Racotumomab (50-200 μg/dose, s.c.) shows no significant antitumor effect in 3LL cell (s.c.) mice xenograft[3].
