The tolerability of a medical product is the degree to which symptomatic and non-symptomatic adverse events associated with the product’s administration affect the ability or desire of the patient to adhere to the dose or intensity of therapy.
Maximum Tolerated Dose (MTD)
The MTD is defined by the highest amount of a substance that can be administered without affecting safety or toxicity.
MTD and Efficacy
Ideally, the MTD is exactly that: maximum. Excessive dosing without benefit is always avoided in studies at Ichor.
