I've been reading about this stuff and ordered some recently. Here is some info I was able to find on it.

Trehalose (α-D-glucopyranosyl α-D-glucopyranoside) is a unique sugar capable of protecting biomolecules against environmental stress and may inhibit the inflammatory cascade that in turn causes oxidative damage and cytokines production
Trehalose inhibits LPS-induced lethality
Endotoxin administration caused a marked decrease in the survival of the rats exposed to a lethal dose of endotoxin (Table 1). Trehalose administration significantly increased the number of surviving animals (Table 1). In contrast, sucrose did not prevent mortality in rats challenged with a lethal dose of LPS

An antitumor activity on oral administration of trehalose was investigated by using ICR mice implanted Sarcoma 180. After implanting of Sarcoma 180, five kinds of saline solutions containing trehalose (10 to 250 mg/kg) were administrated to mice daily for 10 days. The antitumor effect of trehalose was evaluated by measuring tumor sizes for 3 weeks and tumor weights on week 3. Approximately 70% inhibition ratio was observed in the tested groups admistered a dose higher than dose of 25 mg/kg.

25mg per kg is not a large dose. That would be around 2gm for an average person.
