"The patients treated with CLOVA cocktail in combination with TMZ showed increased survival compared to the control group treated with TMZ alone."
CLOVA cocktail:
TMZ + 800 mg cimetidine, 400 mg lithium, 10 mg olanzapine, 800 mg valproate.
Perhaps one of these drugs (to inhibit the activity of GSK3β) can be replaced with more effective?
