− Key Results from Phase 3 ALTA 1L Sub-Analyses Further Support ALUNBRIG’s Strong Intracranial Efficacy and Enhanced Quality of Life in First-Line ALK+ NSCLC
− Positive 10-Month Follow-Up Data from Phase 1/2 Trial Reaffirm Mobocertinib’s Previously Reported Results in Patients with EGFR Exon20 Insertion+ Metastatic NSCLC
Takeda Pharmaceutical Company Limited (TSE:4502/NYSE:TAK) (“Takeda”) today announced that the company is presenting data from its lung cancer portfolio at the virtual European Society for Medical Oncology (ESMO) conference. Notably, insights from sub-analyses of the Phase 3 ALTA 1L study reinforce both the compelling evidence of intracranial efficacy with ALUNBRIG® (brigatinib) as a first-line treatment for patients with anaplastic lymphoma kinase-positive (ALK+) non-small cell lung cancer (NSCLC) as well as associated quality of life (QoL) data. Takeda is also featuring updated 10-month follow-up results from the Phase 1/2 trial of mobocertinib (TAK-788), demonstrating mobocertinib achieved a duration of response (DoR) of more than one year in the trial’s study population of patients with epidermal growth factor receptor (EGFR) Exon20 insertion+ metastatic NSCLC (mNSCLC).
“We’re pleased to present our ongoing research in lung cancer at this year’s virtual ESMO congress, including new results from our ongoing Phase 3 ALTA 1L trial, which reinforce ALUNBRIG’s superiority over crizotinib and underscore the strength of the data upon which ALUNBRIG earned its recent first-line indication in the U.S. and European Union,” said Christopher Arendt, Head, Oncology Therapeutic Area Unit, Takeda. “Additionally, updated data from the Phase 1/2 trial of mobocertinib showed a prolonged duration of response in patients with EGFR Exon20 insertion+ mNSCLC, representing promising progress for an underserved population that derives limited efficacy from currently available treatments.”
Results from sub-analyses of the Phase 3 ALTA 1L study, featured in two poster sessions, provide additional insight into ALUNBRIG’s intracranial efficacy and improvements in QoL in the first-line setting. ALUNBRIG significantly prolonged time to intracranial disease progression versus crizotinib in patients with ALK tyrosine kinase inhibitor (TKI)-naïve ALK+ NSCLC, showcasing robust intracranial activity. Key findings as assessed by a blinded independent review committee (BIRC) among patients with baseline brain metastases showed:
- An average of 24 months (12.9–NR) passed before intracranial disease progression in patients treated with ALUNBRIG compared to 5.6 months for crizotinib (4.0–9.2).
- ALUNBRIG demonstrated a significant improvement in overall progression-free survival (PFS) in patients who had no prior brain radiotherapy, yielding an average of 24 months versus 5.5 months with crizotinib (hazard ratio [HR]: 0.27, P=0.0003).
- The brain was the first site of disease progression less frequently in patients treated with ALUNBRIG (31%) than with crizotinib (42%).
- ALUNBRIG continued to demonstrate improvements in global health status (GHS)/QoLcompared to crizotinib with significantly delayed time to deterioration in patients with baseline brain metastases (16.6 months versus 4.7 months for crizotinib [HR: 0.54, 95% CI 0.29‒1.00; P=0.0415]).
- Serious adverse reactions occurred in 33% of patients receiving ALUNBRIG. The most common serious adverse reactions other than disease progression were pneumonia (4.4%), ILD/pneumonitis (3.7%), pyrexia (2.9%), dyspnea (2.2%), pulmonary embolism (2.2%) and asthenia (2.2%). Fatal adverse reactions other than disease progression occurred in 2.9% of patients and included pneumonia (1.5%), cerebrovascular accident (0.7%) and multiple organ dysfunction syndrome (0.7%).
“Ongoing results from the ALTA 1L trial demonstrate brigatinib as an effective first-line treatment option for ALK+ NSCLC patients, especially those with baseline brain metastases,” said Professor Sanjay Popat, Consultant Medical Oncologist, The Royal Marsden NHS Foundation Trust. “While we now have several targeted treatment options available to treat the disease, therapies that have demonstrated robust intracranial efficacy have shown to be an invaluable addition as we seek to extend and improve the lives of our patients.”
Key findings from an on-demand mini oral sessionfeaturing results from the Phase 1/2 trial of mobocertinib with 10 months of follow up will also be presented. Confirmed responders treated with mobocertinib maintained a response for an average of more than one year, with a median DoR of 13.9 months (5.0-NR). With additional follow-up, the trial maintained a 43% (12/28; 95% CI 24‒63) confirmed objective response rate (ORR) and a median PFS of 7.3 months (95% CI 4.4‒15.6) among the total patients treated. The safety profile of mobocertinib was manageable. For patients with EGFR Exon20 insertion+ mNSCLC treated at the 160 mg once daily dose, the most common adverse reactions (>=25%) were diarrhea (89%), decreased appetite (54%), vomiting (54%), rash (46%), nausea (46%) and anemia (36%). Among all patients treated at the 160 mg once daily dose, the most common treatment-related adverse events (TRAEs) were diarrhea (88%), nausea (49%), vomiting (36%) and rash (35%).
Data from the pivotal Phase 2 extension cohort of mobocertinib, EXCLAIM, will read out in fiscal year 2020.
About ALUNBRIG® (brigatinib)
ALUNBRIG is a potent and selective next-generation tyrosine kinase inhibitor (TKI) that was designed to target anaplastic lymphoma kinase (ALK) molecular alterations.
ALUNBRIG is approved in the U.S. and European Union (EU) as a first-line treatment for patients with ALK-positive (ALK+) metastatic non-small cell lung cancer (mNSCLC) previously not treated with an ALK inhibitor. ALUNBRIG is also approved in more than 40 countries, including the U.S., Canada and the EU, for the treatment of people living with ALK+ mNSCLC who have taken the medicine crizotinib, but their NSCLC has worsened or they cannot tolerate taking crizotinib.
About ALK+ NSCLC
Non-small cell lung cancer (NSCLC) is the most common form of lung cancer, accounting for approximately 85% of the estimated 1.8 million new cases of lung cancer diagnosed each year worldwide, according to the World Health Organization.1,2 Genetic studies indicate that chromosomal rearrangements in anaplastic lymphoma kinase (ALK) are key drivers in a subset of NSCLC patients.3 Approximately three to five percent of patients with metastatic NSCLC have a rearrangement in the ALK gene.4,5,6 ALK+ NSCLC is a complex and nuanced disease that presents treatment challenges for newly diagnosed patients, especially those whose disease has spread to their brain.
Takeda is committed to continuing research and development in NSCLC to improve the lives of the approximately 40,000 patients diagnosed with this serious and rare form of lung cancer worldwide each year.7
About Mobocertinib (TAK-788)
Mobocertinib is a potent, small-molecule tyrosine kinase inhibitor (TKI) specifically designed to selectively target epidermal growth factor receptor (EGFR) and human EGFR2 (HER2) Exon20 insertion mutations. In 2019, the U.S. FDA granted mobocertinib Orphan Drug Designation for the treatment of lung cancer with HER2 mutations or EGFR mutations including Exon20 insertion mutations. In April 2020, mobocertinib received Breakthrough Therapy Designation from the FDA for patients with EGFR Exon20 insertion+ metastatic non-small cell lung cancer (mNSCLC) whose disease has progressed on or after platinum-based chemotherapy.
The mobocertinib development program began in the NSCLC population and is expected to expand to additional underserved populations in other tumor types. Mobocertinib is an investigational drug for which efficacy and safety have not been established.
About EGFR Exon20 Insertion+ mNSCLC
Patients with epidermal growth factor receptor (EGFR) Exon20 insertion+ metastatic non-small cell lung cancer (mNSCLC) make up only about 1-2% of patients with NSCLC.8,9 This disease carries a worse prognosis than other EGFR mutations because there are currently no FDA-approved therapies that target Exon20 mutations, and current EGFR TKIs and chemotherapy provide limited benefit for these patients.
Takeda is committed to continuing research and development in EGFR Exon20 insertion+ mNSCLC with the hope of introducing a targeted treatment option for the approximately 30,000 patients diagnosed with the disease worldwide each year.8,9
ALUNBRIG IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Interstitial Lung Disease (ILD)/Pneumonitis: Severe, life-threatening, and fatal pulmonary adverse reactions consistent with interstitial lung disease (ILD)/pneumonitis have occurred with ALUNBRIG. In the ALUNBRIG arm of trial ALTA 1L (180 mg once daily), ILD/pneumonitis occurred in 5.1% of patients receiving ALUNBRIG. ILD/pneumonitis occurred within 8 days of initiation of ALUNBRIG in 2.9% of patients, with Grade 3 to 4 reactions occurring in 2.2% of patients. In Trial ALTA, ILD/pneumonitis occurred in 3.7% of patients in the 90 mg group (90 mg once daily) and 9.1% of patients in the 90→180 mg group (180 mg once daily with 7-day lead-in at 90 mg once daily). Adverse reactions consistent with possible ILD/pneumonitis occurred early within 9 days of initiation of ALUNBRIG (median onset was 2 days) in 6.4% of patients, with Grade 3 to 4 reactions occurring in 2.7%. Monitor for new or worsening respiratory symptoms (e.g., dyspnea, cough, etc.), particularly during the first week of initiating ALUNBRIG. Withhold ALUNBRIG in any patient with new or worsening respiratory symptoms, and promptly evaluate for ILD/pneumonitis or other causes of respiratory symptoms (e.g., pulmonary embolism, tumor progression, and infectious pneumonia). For Grade 1 or 2 ILD/pneumonitis, either resume ALUNBRIG with dose reduction after recovery to baseline or permanently discontinue ALUNBRIG. Permanently discontinue ALUNBRIG for Grade 3 or 4 ILD/pneumonitis or recurrence of Grade 1 or 2 ILD/pneumonitis.
Hypertension: In the ALUNBRIG arm of trial ALTA 1L (180 mg once daily), hypertension was reported in 32% of patients receiving ALUNBRIG; Grade 3 hypertension occurred in 13% of patients.

Withhold ALUNBRIG for Grade 3 or 4 pancreatic enzyme elevation. Upon resolution or recovery to Grade 1 or baseline, resume ALUNBRIG at the same dose or at a reduced dose.
Hyperglycemia: In the ALUNBRIG arm of trial ALTA 1L (180 mg once daily), 56% of patients who received ALUNBRIG experienced new or worsening hyperglycemia. Grade 3 hyperglycemia, based on laboratory assessment of serum fasting glucose levels, occurred in 7.5% of patients. In ALTA, 43% of patients who received ALUNBRIG experienced new or worsening hyperglycemia. Grade 3 hyperglycemia, based on laboratory assessment of serum fasting glucose levels, occurred in 3.7% of patients. Two of 20 (10%) patients with diabetes or glucose intolerance at baseline required initiation of insulin while receiving ALUNBRIG. Assess fasting serum glucose prior to initiation of ALUNBRIG and monitor periodically thereafter. Initiate or optimize anti-hyperglycemic medications as needed. If adequate hyperglycemic control cannot be achieved with optimal medical management, withhold ALUNBRIG until adequate hyperglycemic control is achieved and consider reducing the dose of ALUNBRIG or permanently discontinuing ALUNBRIG.
Embryo-Fetal Toxicity: Based on its mechanism of action and findings in animals, ALUNBRIG can cause fetal harm when administered to pregnant women. There are no clinical data on the use of ALUNBRIG in 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 ALUNBRIG and for at least 4 months following the final dose. Advise males with female partners of reproductive potential to use effective contraception during treatment and for at least 3 months after the last dose of ALUNBRIG.

DRUG INTERACTIONS
CYP3A Inhibitors: Avoid coadministration of ALUNBRIG with strong or moderate CYP3A inhibitors. Avoid grapefruit or grapefruit juice as it may also increase plasma concentrations of brigatinib. If coadministration of a strong or moderate CYP3A inhibitor cannot be avoided, reduce the dose of ALUNBRIG.
CYP3A Inducers: Avoid coadministration of ALUNBRIG with strong or moderate CYP3A inducers. If coadministration of moderate CYP3A inducers cannot be avoided, increase the dose of ALUNBRIG.
CYP3A Substrates:Coadministration of ALUNBRIG with sensitive CYP3A substrates, including hormonal contraceptives, can result in decreased concentrations and loss of efficacy of sensitive CYP3A substrates.
USE IN SPECIFIC POPULATIONS
Pregnancy: ALUNBRIG can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus.
Lactation: There are no data regarding the secretion of brigatinib in human milk or its effects on the breastfed infant or milk production. Because of the potential adverse reactions in breastfed infants, advise lactating women not to breastfeed during treatment with ALUNBRIG.
Females and Males of Reproductive Potential:
Pregnancy Testing: Verify pregnancy status in females of reproductive potential prior to initiating ALUNBRIG.
Contraception: Advise females of reproductive potential to use effective non-hormonal contraception during treatment with ALUNBRIG and for at least 4 months after the final dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with ALUNBRIG and for at least 3 months after the final dose.
Infertility:ALUNBRIG may cause reduced fertility in males.
Pediatric Use: The safety and effectiveness of ALUNBRIG in pediatric patients have not been established.
Geriatric Use: Of the 359 patients enrolled in the ALTA 1L ALUNBRIG arm and in ALTA, 26.7% were 65 and older and 7.5% were 75 and older. No clinically relevant differences in safety or efficacy were observed between patients ≥65 years and younger patients.
Hepatic or Renal Impairment: No dose adjustment is recommended for patients with mild or moderate hepatic impairment or mild or moderate renal impairment. Reduce the dose of ALUNBRIG for patients with severe hepatic impairment or severe renal impairment.
