Margetuximab is under clinical development by MacroGenics and currently in Phase II for Gastric Cancer. According to GlobalData, Phase II drugs for Gastric Cancer have a 32% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how Margetuximab’s drug-specific PTSR and Likelihood of Approval (LoA) scores compare to the indication benchmarks. Buy the report here.

GlobalData tracks drug-specific phase transition and likelihood of approval scores, in addition to indication benchmarks based off 18 years of historical drug development data. Attributes of the drug, company and its clinical trials play a fundamental role in drug-specific PTSR and likelihood of approval.

Margetuximab overview

Margetuximab (Margenza) is a Fc-engineered human epidermal receptor growth factor-2 directed IgG1 kappa monoclonal antibody. It is the biobetter version of trastuzumab. It is formulated as injectable solution for intravenous route of administration. Margenza is indicated in combination with chemotherapy, for the treatment of adult patients with metastatic HER2-positive breast cancer who have received two or more prior HER2 regimens, at least one of which was for metastatic disease. Margetuximab (MGAH22) is under development for the treatment of solid tumor, small-cell lung cancer, non-small cell lung cancer, diffuse large B-cell lymphoma, metastatic breast cancer, gastroesophageal cancer, adenocarcinoma of the gastroesophageal junction, epithelial ovarian cancer, hepatocellular carcinoma (HCC), SCCHN, metastatic cervical cancer, TNBC, intrahepatic bile duct epithelial cell carcinoma (Metastatic Bile Duct Cancer), Extrahepatic Bile Duct Cancer, gallbladder cancer and gastric cancer. The therapeutic candidate is monospecific, bivalent and it’s half life last from days to weeks. It is also under development for the treatment of relapsed/refractory advanced HER2+ gastroesophageal junction or gastric cancer. The therapeutic candidate is administered by intravenous infusion. It is a HER2 mAb with specificity and affinity similar to trastuzumab. It was also under development for colorectal cancer, head and neck cancer. It is derived from the Fc Optimization technology platform.

GlobalData, the leading provider of industry intelligence, provided the underlying data, research, and analysis used to produce this article.

GlobalData’s Likelihood of Approval analytics tool dynamically assesses and predicts how likely a drug will move to the next stage in its clinical pathway (PTSR), as well as how likely the drug will be approved (LoA). This is based on a proprietary algorithm built from the drugs’ sales forecast, regulatory milestones, cost forecasts, WACC rate and other proprietary data sources found on GlobalData’s Pharmaceutical Intelligence Center.
