'''Depatuxizumab mafodotin''' (also known as '''ABT-414''') is an [[antibody-drug conjugate]] designed to deliver the cytotoxic agent [[monomethyl auristatin F]] (MMAF) to cells expressing the [[Epidermal Growth Factor Receptor]] (EGFR). It is being developed by [[AbbVie]] for the treatment of [[glioblastoma]].

==Overview==
'''Depatuxizumab mafodotin''' is an [[antibody-drug conjugate]] (ADC) designed for the treatment of certain types of [[cancer]]. It combines a monoclonal antibody targeting the [[epidermal growth factor receptor]] (EGFR) with a potent cytotoxic agent, mafodotin, which is a derivative of the microtubule-disrupting agent [[monomethyl auristatin F]] (MMAF).


Depatuxizumab mafodotin targets the EGFR, a protein that is overexpressed in many types of cancer, including glioblastoma. The drug is composed of an [[antibody]] that binds to the EGFR, linked to the cytotoxic agent MMAF. Once the drug binds to the EGFR on the surface of a cancer cell, it is internalized and the MMAF is released, leading to cell death.
==Mechanism of Action==
Depatuxizumab mafodotin works by specifically targeting and binding to EGFR, which is overexpressed in various [[tumors]]. Upon binding, the ADC is internalized by the cancer cell, where the cytotoxic agent mafodotin is released. This agent disrupts the microtubule network within the cell, leading to cell cycle arrest and apoptosis.

==Development and Clinical Trials==
Depatuxizumab mafodotin has been evaluated in several [[clinical trials]] for its efficacy and safety in treating [[glioblastoma]] and other EGFR-expressing tumors. The results have shown promise, particularly in patients with recurrent glioblastoma.


Depatuxizumab mafodotin has been evaluated in several [[clinical trial]]s for the treatment of glioblastoma. In a Phase II trial, the drug showed promising results, with a median overall survival of 7.3 months in patients with recurrent glioblastoma. However, in a Phase III trial, the drug did not meet its primary endpoint of improving overall survival compared to [[temozolomide]].
==Side Effects==
The administration of depatuxizumab mafodotin can lead to various side effects, including [[ocular toxicity]], [[fatigue]], and [[hematologic toxicity]]. These side effects are primarily due to the action of the cytotoxic agent mafodotin.

Overview[edit]

Depatuxizumab mafodotin is an antibody-drug conjugate (ADC) designed for the treatment of certain types of cancer. It combines a monoclonal antibody targeting the epidermal growth factor receptor (EGFR) with a potent cytotoxic agent, mafodotin, which is a derivative of the microtubule-disrupting agent monomethyl auristatin F (MMAF).

Mechanism of Action[edit]

Depatuxizumab mafodotin works by specifically targeting and binding to EGFR, which is overexpressed in various tumors. Upon binding, the ADC is internalized by the cancer cell, where the cytotoxic agent mafodotin is released. This agent disrupts the microtubule network within the cell, leading to cell cycle arrest and apoptosis.

Development and Clinical Trials[edit]

Depatuxizumab mafodotin has been evaluated in several clinical trials for its efficacy and safety in treating glioblastoma and other EGFR-expressing tumors. The results have shown promise, particularly in patients with recurrent glioblastoma.

Side Effects[edit]

The administration of depatuxizumab mafodotin can lead to various side effects, including ocular toxicity, fatigue, and hematologic toxicity. These side effects are primarily due to the action of the cytotoxic agent mafodotin.
