Takeda’s EXKIVITY® (mobocertinib) Receives Approval from the NMPA of China, Becoming the First and Only Therapy Available for Patients with EGFR Exon20 Insertion+ NSCLC

– EXKIVITY is the First Category-1 Innovative Drug Approved for Takeda China Following a Phase 2 Global Pivotal Study

– Approval Based on Data from the Phase 1/2 Clinical Trial Demonstrating EXKIVITY’s Clinical Benefit and Durable Responses in EGFR Exon20 Insertion+ NSCLC

– Results Demonstrated a Confirmed Overall Response Rate (ORR) of 28% and Median Duration of Response (DoR) of 15.8 Months per Independent Review Committee (IRC)

Takeda (TSE:4502/NYSE:TAK) today announced that EXKIVITY^® (mobocertinib) has been approved by the National Medical Products Administration (NMPA) of China for the treatment of adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) Exon20 insertion mutations, whose disease has progressed on or after platinum-based chemotherapy. EXKIVITY has shown clinically meaningful and durable responses in patients with locally advanced or metastatic EGFR Exon20 insertion+ NSCLC and is now the first and only treatment available for this patient population in China. EXKIVITY, an oral tyrosine kinase inhibitor designed to target Exon20 insertions, was reviewed as part of the NMPA’s Breakthrough Therapy program. Full approval for this indication may be contingent upon verification of clinical benefit in a confirmatory trial.

“The approval of EXKIVITY in China for patients with locally advanced or metastatic EGFR Exon20 insertion+ NSCLC was only possible through dedicated collaboration and support from the NMPA and the Chinese government,” said Awny Farajallah, Head, Global Medical Affairs Oncology, Takeda. “Lung cancer is a devastating disease, and we know the discovery and delivery of precision medicines like EXKIVITY to target cancer types that are hard-to-treat have the potential to improve patient outcomes. We are thrilled to introduce EXKIVITY in China as the second lung cancer therapy from Takeda and remain committed to research and development to meet the needs of this patient community.”

Lung cancer is the most commonly diagnosed cancer in China, and NSCLC accounts for approximately 85% of all lung cancer cases in the country.¹ Of those patients diagnosed with EGFR-mutated NSCLC in China, up to 10% harbor Exon20 insertions.^2-7 Despite this prevalence, patients in China have lacked a targeted treatment option designed to address cancers driven by these mutations.

“Since the discovery of EGFR mutations nearly twenty years ago, patients with Exon20 insertions have been waiting for a targeted therapy to treat their disease,” said Sean Shan, President of Takeda China. “The approval of EXKIVITY in China is a remarkable breakthrough, demonstrating the strong commitment of the Chinese government to encourage and accelerate the introduction of innovative therapies. EXKIVITY offers a targeted, oral therapy to a population that has been historically underserved, and this approval brings us one step closer to defeating this complex and heterogeneous disease for patients in this region.”

This approval is based on the results from the platinum-pretreated population in the Phase 1/2 trial of EXKIVITY, which consisted of 114 patients with EGFR Exon20 insertion+ NSCLC who received prior platinum-based therapy and were treated at the 160 mg dose. Results demonstrated a confirmed ORR of 28% per IRC as well as a median DoR of 15.8 months per IRC, a median overall survival (OS) of 20.2 months and a median progression-free survival (PFS) of 7.3 months per IRC. The most common treatment-related adverse reactions (TRAEs) were diarrhea (92%), rash (46%), paronychia (38%) and decreased appetite (37%).

About EGFR Exon20 Insertion+ NSCLC

Non-small cell lung cancer (NSCLC) is the most common form of lung cancer, accounting for approximately 85% of the estimated 2.2 million new cases of lung cancer diagnosed each year worldwide, according to the World Health Organization.^{9, 10} Patients with epidermal growth factor receptor (EGFR) Exon20 insertion+ NSCLC make up approximately 1-2% of patients with NSCLC, and the disease is more common in Asian populations compared to Western populations.^2-6 This disease carries a worse prognosis than other EGFR mutations, as EGFR TKIs – which do not specifically target EGFR Exon20 insertions – and chemotherapy provide limited benefit for these patients.

Takeda is committed to continuing research and development to meet the needs of the lung cancer community through the discovery and delivery of transformative medicines.

EXKIVITY IMPORTANT SAFETY INFORMATION

QTc Interval Prolongation

Heart rate-corrected QT (QTc) interval prolongation, including resultant life-threatening arrhythmias, such as Torsades de Pointes, occurred in patients treated with mobocertinib.

A concentration-dependent QTc interval prolongation of approximately 12.7 msec (90% CI: 8.69, 16.8) was observed at the steady-state C_max following 160 mg daily doses based on an analysis of data from 194 patients with advanced solid malignances.

Clinical trials of mobocertinib did not enroll patients with baseline QTc greater than 470 msec. Assess QTc and electrolytes at baseline and correct abnormalities in sodium, potassium, calcium, and magnesium prior to initiating mobocertinib. Monitor QTc and electrolytes periodically during treatment. Increase monitoring frequency in patients with risk factors for QTc prolongation, such as in patients with congenital long QTc syndrome, heart disease, electrolyte abnormalities, or those who are taking medicinal products known to prolong the QTc interval. Avoid concomitant use of medicinal products which are known to prolong the QTc interval. Avoid concomitant use of strong or moderate CYP3A inhibitors with mobocertinib, which may further prolong the QTc interval. Permanently discontinue mobocertinib in patients who develop QTc interval prolongation with signs or symptoms of life-threatening arrhythmia.

Interstitial Lung Disease/Pneumonitis

Severe, life-threatening, and fatal interstitial lung disease (ILD)/pneumonitis have occurred in patients treated with mobocertinib.

Withhold mobocertinib for acute onset of new or progressive unexplained pulmonary symptoms such as dyspnea, cough, and fever pending diagnostic evaluation and diagnosis confirmation. Permanently discontinue mobocertinib if ILD/pneumonitis is confirmed.

Cardiac Toxicity

Cardiac failure (including congestive cardiac failure, decreased ejection fraction, and cardiomyopathy) has occurred in patients treated with mobocertinib.

Mobocertinib can cause QTc prolongation resulting in Torsades de Pointes.

Atrial fibrillation (1.3%), ventricular tachycardia (0.3%), first degree atrioventricular block (0.7%), second degree atrioventricular block (0.3%), left bundle branch block (0.3%), supraventricular extrasystoles (0.3%) and ventricular extrasystoles (0.3%) also occurred in patients receiving mobocertinib. The causality of these events to mobocertinib has not been established.

Conduct cardiac monitoring, including assessment of left ventricular ejection fraction at baseline and during treatment. Patients who develop signs and symptoms consistent with cardiac failure should be treated as clinically indicated. Withhold, reduce the dose, or permanently discontinue mobocertinib based on the severity.

Diarrhea

In clinical studies, most patients experienced mild to moderate diarrhea. Diarrhea can be severe or life threatening. The median time to first onset of diarrhea was five days but could occur as soon as 24 hours after administration of mobocertinib. Diarrhea is usually transient and had a median time to resolution of three days. Prolonged diarrhea may lead to dehydration or electrolyte imbalance, with or without renal impairment.

Early and compliant diarrhea management such as prescribed anti-diarrheal medicinal products (e.g., loperamide), diet, adequate fluid intake (~2L clear liquids per day), and patient education is recommended. Instruct patients to have anti-diarrheal medicinal products (e.g., loperamide) readily available. Begin anti-diarrheal treatment at the first episode of poorly formed or loose stools or the earliest onset of bowel movements more frequent than normal. In mobocertinib clinical trials where loperamide was used as the antidiarrheal, the dosage regimen for loperamide was 4 mg at the first bout of diarrhea and then 2 mg every 2 hours until the patient is diarrhea-free for at least 12 hours; daily dose of loperamide did not exceed 16 mg. If using loperamide as the antidiarrheal treatment, refer to loperamide product labeling for additional information.

If diarrhea does not improve or additional signs or symptoms are reported, standard medical practice intervention, including other anti-diarrheal medications, are recommended. Antidiarrheal prophylaxis may be considered as needed. Monitor electrolytes and instruct patients to increase fluid and electrolyte intake as needed. No dose modification is necessary unless the patient does not tolerate mobocertinib or the symptoms recur, or the diarrhea doesn’t resolve with medical intervention. Interrupt mobocertinib and reduce subsequent doses if severe diarrhea occurs.

Embryo-Fetal Toxicity

Based on its mechanism of action and data from animal studies, mobocertinib can cause fetal harm when administered to pregnant women.

Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective non-hormonal contraception during treatment with mobocertinib and for one month following the final dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with mobocertinib and for one week following the final dose of mobocertinib.
