Data from an ongoing clinical study of tisotumab vedotin in solid tumors has demonstrated activity in the treatment of cervical cancer; 11 of 34 evaluable patients achieved a response; with a median time of treatment of 4.9 months and 7 responders are still ongoing or in follow up for progression. The GEN701 study is ongoing and further data in both cervical cancer and other solid tumor indications will be published at a later date.
Each year in the United States, more than 12,000 women are diagnosed with cervical cancer and more than 4,000 die of the disease. Traditional chemotherapy drugs have limited effectiveness against advanced cervical cancer, highlighting the importance of finding new ways to treat this disease.
Precision cancer medicine: Unlike traditional chemotherapy, which attacks any cell in the body that is rapidly dividing, precision cancer medicine aims to target specific genetic alterations that allow cancer cells to grow. Most or all cancers result from abnormal genes or gene regulation. The strategy of precision cancer medicine is to define abnormalities at the most basic genetic level. These abnormalities in the DNA are called genomic alterations and they are responsible for driving cancer cell growth. Once the abnormality is identified, genomic tests are created to measure the specific genes in cervical cancer that are abnormal or are not working properly. By identifying the genomic changes and knowing which genes are altered in a patient, cancer drugs that specifically attack that gene (or the later consequences of that gene) can be used to precisely target the cancer and avoid affecting healthy cells.
About Tisotumab Vedotin
Tisotumab vedotin is an antibody-drug conjugate (ADC) composed of a human antibody that binds to tissue factor (TF) conjugated to Seattle Genetics’ clinically validated cytotoxic drug MMAE. TF is a protein involved in tumor signaling and angiogenesis. Based on its high expression on many solid tumors and its rapid internalization, TF was selected as a target for an ADC approach.
About the GEN701 study
The GEN701 study is a 173 patient, two-part clinical trial of tisotumab vedotin in seven types of solid tumors: ovarian, cervical, endometrium, bladder, prostate, esophageal, and lung.
