On August 21, 2015 Takeda Pharmaceutical Company Limited (TSE: 4502) reported that the European Medicines Agency (EMA) has accepted the Marketing Authorization Application (MAA) for ixazomib, an investigational oral proteasome inhibitor for the treatment of patients with relapsed and/or refractory multiple myeloma (Press release, Takeda, AUG 21, 2015, View Source [SID:1234507307]). On July 23, ixazomib was granted accelerated assessment by the Committee for Medicinal Products for Human Use (CHMP) of the EMA, a designation reserved for those medicines deemed to be of major public health interest and, in particular, therapeutic innovation.

"The ixazomib applications in Europe and the United States are the first of several that we anticipate submitting by the end of this fiscal year," said Melody Brown, Vice President of Regulatory Affairs, Takeda. "By filing in many regions in rapid succession, we hope to bring ixazomib to as many people living with relapsed/refractory multiple myeloma as soon as possible. We express our thanks to the patients and physicians participating in the TOURMALINE clinical trial program globally as their support has been critical in making these filings possible."

The MAA submission was primarily based on the results of the first pre-specified interim analysis of the pivotal Phase 3 trial TOURMALINE-MM1, an international, randomized, double-blind, placebo controlled clinical trial of 722 patients designed to evaluate the superiority of ixazomib plus lenalidomide and dexamethasone over placebo plus lenalidomide and dexamethasone in adult patients with relapsed and/or refractory multiple myeloma. Patients continue to be treated to progression in this trial and will be evaluated for long-term outcomes.

In addition to the ixazomib MAA submission with the EMA, a New Drug Application for ixazomib was filed with the U.S. Food and Drug Administration (FDA). Additional filings in other countries are planned to begin later this fiscal year.

About Multiple Myeloma
Multiple myeloma is a cancer of the plasma cells, which are found in the bone marrow. In multiple myeloma, a group of plasma cells, or myeloma cells, becomes cancerous and multiplies, increasing the number of plasma cells to a higher than normal level. Because plasma cells circulate widely in the body, they have the potential to affect many bones in the body, possibly resulting in compression fractures, lytic bone lesions and related pain. Multiple myeloma can cause a number of serious health problems affecting the bones, immune system, kidneys and red blood cell count, with some of the more common symptoms including bone pain and fatigue, a symptom of anemia. Multiple myeloma is a rare form of cancer with approximately 39,000 new cases in the EU and 114,000 new cases globally per year.

About Ixazomib
Ixazomib is an investigational oral proteasome inhibitor which is being studied in multiple myeloma, systemic light-chain (AL) amyloidosis, and other malignancies. Ixazomib was granted orphan drug designation in multiple myeloma in both the U.S. and Europe in 2011 and for AL amyloidosis in both the U.S. and Europe in 2012. Ixazomib received Breakthrough Therapy status by the U.S. FDA for relapsed or refractory AL amyloidosis in 2014. It is also the first oral proteasome inhibitor to enter Phase 3 clinical trials.

Ixazomib’s clinical development program further reinforces Takeda’s ongoing commitment to developing innovative therapies for people living with multiple myeloma worldwide and the healthcare professionals who treat them. Five global Phase 3 trials are ongoing:

TOURMALINE-MM1, investigating ixazomib vs. placebo, in combination with lenalidomide and dexamethasone in relapsed and/or refractory multiple myeloma
TOURMALINE-MM2, investigating ixazomib vs. placebo, in combination with lenalidomide and dexamethasone in patients with newly diagnosed multiple myeloma
TOURMALINE-MM3, investigating ixazomib vs. placebo as maintenance therapy in patients with newly diagnosed multiple myeloma following induction therapy and autologous stem cell transplant (ASCT)
TOURMALINE-MM4, investigating ixazomib vs. placebo as maintenance therapy in patients with newly diagnosed multiple myeloma who have not undergone ASCT
TOURMALINE-AL1, investigating ixazomib plus dexamethasone vs. physician choice of selected regimens in patients with relapsed or refractory AL amyloidosis
