On July 26, 2016 Genmab A/S (Nasdaq Copenhagen: GEN) reported that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation for DARZALEX (daratumumab) injection in combination with lenalidomide and dexamethasone, or bortezomib and dexamethasone for the treatment of patients with multiple myeloma who have received at least one prior therapy (Press release, Genmab, JUL 26, 2016, View Source [SID:1234514029]). Breakthrough Therapy Designation is a program intended to expedite the development and review of drugs to treat serious or life-threatening diseases in cases where preliminary clinical evidence shows that the drug may provide substantial improvements over available therapy. In August 2012, Genmab granted Janssen Biotech, Inc. an exclusive worldwide license to develop and commercialize daratumumab. Schedule your 30 min Free 1stOncology Demo! "This is the second time daratumumab has earned the distinction of a Breakthrough Therapy Designation. We are pleased that the FDA continues to recognize the potential of daratumumab to help patients with multiple myeloma. We continue to work with our strategic partner Janssen and the regulatory authorities to advance daratumumab to bring this treatment to more patients suffering from multiple myeloma as quickly as possible," said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab.

The Breakthrough Therapy Designation for daratumumab was granted on the basis of data from two Phase III studies: CASTOR (MMY3004; NCT02136134) evaluating daratumumab in combination with bortezomib and dexamethasone versus bortezomib and dexamethasone alone in patients with relapsed or refractory multiple myeloma, and POLLUX (MMY3003; NCT02076009) evaluating daratumumab in combination with lenalidomide and dexamethasone versus lenalidomide and dexamethasone in patients with relapsed or refractory multiple myeloma.
About Breakthrough Therapy Designation
The Breakthrough Therapy Designation was enacted as part of the 2012 FDA Safety and Innovation Act (FDASIA) and is intended to expedite development of drugs to treat serious and life-threatening medical conditions when preliminary clinical evidence demonstrates that the drug may have substantial improvement on at least one clinically significant endpoint over available therapies. Breakthrough Therapy Designation includes all the features of the Fast Track Designation, as well as more intensive guidance from the FDA on a drug’s clinical development program.
About DARZALEX (daratumumab)
DARZALEX (daratumumab) injection for intravenous infusion is indicated in the United States for the treatment of patients with multiple myeloma who have received at least three prior lines of therapy, including a proteasome inhibitor (PI) and an immunomodulatory agent, or who are double-refractory to a PI and an immunomodulatory agent.1 DARZALEX is the first monoclonal antibody (mAb) to receive U.S. Food and Drug Administration (FDA) approval to treat multiple myeloma. DARZALEX is indicated in Europe for use as monotherapy for the treatment of adult patients with relapsed and refractory multiple myeloma, whose prior therapy included a PI and an immunomodulatory agent and who have demonstrated disease progression on the last therapy.

Daratumumab is a human IgG1k monoclonal antibody (mAb) that binds with high affinity to the CD38 molecule, which is highly expressed on the surface of multiple myeloma cells. It is believed to induce rapid tumor cell death through programmed cell death, or apoptosis,1,2 and multiple immune-mediated mechanisms, including complement-dependent cytotoxicity,1,2 antibody-dependent cellular phagocytosis3,4 and antibody-dependent cellular cytotoxicity.1,2 In addition, daratumumab therapy results in a reduction of immune-suppressive myeloid derived suppressor cells (MDSCs) and subsets of regulatory T cells (Tregs) and B cells (Bregs), all of which express CD38. These reductions in MDSCs, Tregs and Bregs were accompanied by increases in CD4+ and CD8+ T cell numbers in both the peripheral blood and bone marrow.1,5
Daratumumab is being developed by Janssen Biotech, Inc. under an exclusive worldwide license to develop, manufacture and commercialize daratumumab from Genmab. Five Phase III clinical studies with daratumumab in relapsed and frontline settings are currently ongoing, and additional studies are ongoing or planned to assess its potential in other malignant and pre-malignant diseases on which CD38 is expressed, such as smoldering myeloma, non-Hodgkin’s lymphoma and a solid tumor indication.
