Brentuximab vedotin

Brentuximab vedotin, also known as Adcetris®, is an antibody-drug conjugate that combines an anti-CD30 antibody with the drug monomethyl auristatin E (MMAE). It is an anti-neoplastic agent used in the treatment of Hodgkin's lymphoma and systemic anaplastic large cell lymphoma. Brentuximab vedotin was initially approved in 2011. In January 2012, the drug label was revised with a boxed warning of a condition known as progressive multifocal leukoencephalopathy and death due to opportunistic JC virus infection post treatment .

The U.S. Food and Drug Administration approved Adcetris in March 2018 to treat adult patients with previously untreated stage III or IV classical Hodgkin lymphoma (cHL) in combination with chemotherapy .

Adcetris has also been previously approved by the FDA to treat Hodgkin's lymphoma after relapse, Hodgkin's lymphoma after stem cell transplantation when a patient has a high risk of relapse or progression, systemic anaplastic large cell lymphoma (ALCL) after the failure of other treatment regimens, and primary cutaneous ALCL after failure of other treatment regimens .

Lymphoma is a malignancy that begins in the lymphatic system, which helps to combat infection and disease. Lymphoma may begin anywhere in the body and can spread to nearby lymph nodes. The two main types of lymphoma are Hodgkin lymphoma (also called Hodgkin disease) and non-Hodgkin lymphoma. Most individuals with Hodgkin's lymphoma have the classical type. In this type of lymphoma, large, abnormal lymphocytes (a type of white blood cell) are found in the lymph nodes called Reed-Sternberg cells. With early diagnosis and intervention, patients with Hodgkin lymphoma normally experience long-term remission .

The ECHELON-1 study results demonstrated superior efficacy of the drug combined with a chemotherapy regimen when it is compared to the previous standard of care. Importantly, removing the drug bleomycin, a highly toxic agent, was completely removed from the regimen. This demonstrates meaningful progress in treatment for patients affected by this disease .

Brentuximab vedotin is indicated in adult patients for the treatment of previously untreated stage III or IV classical Hodgkin's lymphoma (cHL) in combination with doxorubicin, vinblastine, and dacarbazine. It is also indicated for the treatment of cHL post-autologous hematopoietic stem cell transplantation (auto-HSCT) in patients at high risk of relapse or progression. Finally, it may be used in the treatment of adult patients with cHL who have previously failed either auto-HSCT or at least two prior multi-agent chemotherapy regimens if they are not candidates for auto-HSCT.

Brentuximab vedotin is additionally indicated in the treatment of previously untreated systemic anaplastic large cell lymphoma (sALCL), or other CD30-expressing peripheral T-cell lymphomas (PTCL), in combination with cyclophosphamide, doxorubicin, and prednisone. It may also be used as monotherapy in sALCL after therapeutic failure of a least one prior multi-agent chemotherapy regimen.

Brentuximab vedotin is also indicated in the treatment of primary cutaneous large anaplastic large cell lymphoma, or CD30-expressing mycosis fungoides, who have received prior systemic therapy.
