GSK's investigational BCMA antibody-drug conjugate receives Breakthrough Therapy Designation from US FDA for relapsed and refractory multiple myeloma
 
GlaxoSmithKline plc (LSE/NYSE: GSK) today announced that it has received Breakthrough Therapy Designation from the U.S. Food and Drug Administration (FDA) for GSK2857916 monotherapy in patients with multiple myeloma who have failed at least three prior lines of therapy, including an anti-CD38 antibody and are refractory to a proteasome inhibitor and an immunomodulatory agent. In October, the European Medicines Agency (EMA) granted PRIME designation to GSK2857916 for the treatment of relapsed and refractory multiple myeloma patients whose prior therapy included a proteasome inhibitor, an immunomodulatory agent and an anti-CD38 antibody.  GSK2857916 is an anti B-cell maturation agent (BCMA) monoclonal antibody-drug conjugate.
 
GSK2857916 has also received orphan drug designation from the EMA and FDA for multiple myeloma.
 
The PRIME and Breakthrough Therapy Designations are based on results from a phase 1 open-label, dose escalation and expansion study in patients with relapsed/refractory multiple myeloma, irrespective of BCMA expression. Data from this ongoing trial will be presented on 11th December in an oral presentation at the 59th annual meeting of the American Society of Hematology meeting in Atlanta.
 
Axel Hoos, SVP Oncology R&D, GSK said "Oncology R&D at GSK is focussed on developing medicines with transformational potential for patients and we are pleased that our investigational antibody-drug conjugate is the first BCMA targeting agent to receive Breakthrough Therapy and PRIME designation.  GSK plans to rapidly advance clinical trials with this promising therapy, alone and in combination with other therapies, to further investigate how GSK2857916 could benefit patients with multiple myeloma. The monotherapy data that we have seen for GSK2857916 support its transformational potential and we look forward to working with regulators as we progress the development programme." 
 
Notes to editors -
Breakthrough Therapy Designation is designed to expedite the development and review of drugs that are intended to treat a serious condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapy on a clinically significant endpoint(s). Drugs that receive breakthrough therapy designation are eligible for all features of FDA's Fast Track Programme.[i]
 
PRIME designation is offered by the European Medicines Agency (EMA) to enhance support for the development of medicines that target an unmet medical need. It is based on enhanced interaction between sponsor companies and the EMA to optimise development plans and speed up evaluation so these medicines can reach patients earlier.[ii]
 
Orphan designation may be granted for therapies intended to treat conditions that affect fewer than 200,000 people in the U.S.  The designation qualifies the sponsor of the drug for various development incentives of the Orphan Drug Act, including tax credits for qualified clinical testing[iii].
 
In Europe, sponsors who obtain Orphan Designation for a potential new medicine benefit from a range of incentives, including protocol assistance, access to the centralised procedure, market exclusivity and fee reductions.[iv]
