Phase 3 Trial of NINLAROTM (ixazomib) as First Line Maintenance Therapy Met Primary Endpoint in Multiple Myeloma Patients not treated with Stem Cell Transplantation

- Results Demonstrated Statistically Significant Improvement in Progression-Free Survival

- Data to be Submitted for Presentation at an Upcoming Medical Meeting

Cambridge, Mass. and Osaka, Japan – Takeda Pharmaceutical Company Limited (TSE: 4502/NYSE: TAK) ("Takeda") today announced the randomized, Phase 3 TOURMALINE-MM4 study met its primary endpoint of progression free survival (PFS). The trial evaluated the effect of single-agent oral NINLARO™ (ixazomib) as a first line maintenance therapy versus placebo in adult patients diagnosed with multiple myeloma not treated with stem cell transplantation. TOURMALINE-MM4 is the first industry sponsored Phase 3 trial to explore the concept of “switch” maintenance, the use of medicines not included in initial induction therapy, in this setting. NINLARO is currently not approved for this specific use.

“We are very encouraged by the results of the TOURMALINE-MM4 trial and continue our forward momentum in developing maintenance options for multiple myeloma patients. Importantly, this is the third positive Phase 3 readout from the TOURMALINE clinical trial program,” said Phil Rowlands, Ph.D., Head, Oncology Therapeutic Area Unit, Takeda. “We remain committed to bringing this convenient and well-tolerated treatment option to patients.”

The safety profile of NINLARO in the maintenance setting was consistent with previously reported results of single-agent NINLARO use, and there were no new safety signals identified in TOURMALINE-MM4.

Full data results will be submitted for presentation at an upcoming medical meeting.

About the TOURMALINE-MM4 Trial

TOURMALINE-MM4 is a randomized, placebo-controlled, double-blind Phase 3 study of 706 patients, designed to determine the effect of single-agent oral NINLARO^TM (ixazomib) maintenance therapy on progression-free survival (PFS), compared to placebo, in adult patients newly diagnosed with multiple myeloma not treated with stem cell transplantation, who have completed 6-12 months of initial therapy and achieved a partial response or better.

About Multiple Myeloma

Multiple myeloma is a life-threatening rare blood cancer that arises from the plasma cells, a type of white blood cell that is made in the bone marrow. These plasma cells become abnormal, multiply and release a type of antibody known as a paraprotein, which causes symptoms of the disease, including bone pain, frequent or recurring infections and fatigue, a symptom of anemia. These malignant plasma cells have the potential to affect many bones in the body and can cause a number of serious health problems affecting the bones, immune system, kidneys and red blood cell count. The typical multiple myeloma disease course includes periods of symptomatic myeloma followed by periods of remission. Nearly 230,000 people around the world live with multiple myeloma, with approximately 114,000 new cases diagnosed globally each year.

About NINLARO^TM (ixazomib) capsules

NINLARO™ (ixazomib) is an oral proteasome inhibitor which is being studied across the continuum of multiple myeloma treatment settings. NINLARO was first approved by the U.S. Food and Drug Administration (FDA) in November 2015 and is indicated in combination with lenalidomide and dexamethasone for the treatment of patients with multiple myeloma who have received at least one prior therapy. NINLARO is currently approved in more than 60 countries, including the United States, Japan and in the European Union, with more than 10 regulatory filings currently under review. It was the first oral proteasome inhibitor to enter Phase 3 clinical trials and to receive approval.

The comprehensive ixazomib clinical development program, TOURMALINE, includes several ongoing pivotal trials, which together are investigating major multiple myeloma patient populations:

• 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 In addition to the TOURMALINE program, ixazomib is being evaluated in multiple therapeutic combinations for various patient populations in investigator initiated studies globally.

NINLARO^TM (ixazomib) capsules: Global Important Safety Information

SPECIAL WARNINGS AND PRECAUTIONS

Thrombocytopenia has been reported with NINLARO (28% vs. 14% in the NINLARO and placebo regimens, respectively) with platelet nadirs typically occurring between Days 14-21 of each 28-day cycle and recovery to baseline by the start of the next cycle. It did not result in an increase in hemorrhagic events or platelet transfusions. Monitor platelet counts at least monthly during treatment with NINLARO and consider more frequent monitoring during the first three cycles. Manage with dose modifications and platelet transfusions as per standard medical guidelines.

Gastrointestinal toxicities have been reported in the NINLARO and placebo regimens respectively, such as diarrhea (42% vs. 36%), constipation (34% vs. 25%), nausea (26% vs. 21%), and vomiting (22% vs. 11%), occasionally requiring use of antiemetic and anti-diarrheal medications, and supportive care.

Peripheral neuropathy was reported with NINLARO (28% vs. 21% in the NINLARO and placebo regimens, respectively). The most commonly reported reaction was peripheral sensory neuropathy (19% and 14% in the NINLARO and placebo regimens, respectively). Peripheral motor neuropathy was not commonly reported in either regimen (< 1%). Monitor patients for symptoms of peripheral neuropathy and adjust dosing as needed.

Peripheral edema was reported with NINLARO (25% vs. 18% in the NINLARO and placebo regimens, respectively). Evaluate patients for underlying causes and provide supportive care, as necessary. Adjust the dose of dexamethasone per its prescribing information or the dose of NINLARO for severe symptoms.

Cutaneous reactions occurred in 19% of patients in the NINLARO regimen compared to 11% of patients in the placebo regimen. The most common type of rash reported in both regimens was maculo-papular and macular rash. Manage rash with supportive care, dose modification or discontinuation.

Hepatotoxicity, drug-induced liver injury, hepatocellular injury, hepatic steatosis, and hepatitis cholestatic have been uncommonly reported with NINLARO. Monitor hepatic enzymes regularly and adjust dose for Grade 3 or 4 symptoms.

Pregnancy- NINLARO can cause fetal harm. Advise male and female patients of reproductive potential to use contraceptive measures during treatment and for an additional 90 days after the final dose of NINLARO. Women of childbearing potential should avoid becoming pregnant while taking NINLARO due to potential hazard to the fetus. Women using hormonal contraceptives should use an additional barrier method of contraception.

Lactation- It is not known whether NINLARO or its metabolites are excreted in human milk. There could be potential adverse events in nursing infants and therefore breastfeeding should be discontinued.

SPECIAL PATIENT POPULATIONS

Hepatic Impairment: Reduce the NINLARO starting dose to 3 mg in patients with moderate or severe hepatic impairment.

Renal Impairment: Reduce the NINLARO starting dose to 3 mg in patients with severe renal impairment or end-stage renal disease (ESRD) requiring dialysis. NINLARO is not dialyzable and, therefore, can be administered without regard to the timing of dialysis.

DRUG INTERACTIONS

Co-administration of strong CYP3A inducers with NINLARO is not recommended.

ADVERSE REACTIONS

The most frequently reported adverse reactions (≥ 20%) in the NINLARO regimen, and greater than in the placebo regimen, were diarrhea (42% vs. 36%), constipation (34% vs. 25%), thrombocytopenia (28% vs. 14%), peripheral neuropathy (28% vs. 21%), nausea (26% vs. 21%), peripheral edema (25% vs. 18%), vomiting (22% vs. 11%), and back pain (21% vs. 16%). Serious adverse reactions reported in ≥ 2% of patients included thrombocytopenia (2%) and diarrhea (2%). For each adverse reaction, one or more of the three drugs was discontinued in ≤ 1% of patients in the NINLARO regimen.
