− Long-Term Results from the Phase 3 ALTA 1L Trial Established ALUNBRIG as a Superior First-Line Treatment Compared to Crizotinib for People with ALK+ Metastatic NSCLC, Including those with Brain Metastases
CAMBRIDGE, Mass. & OSAKA, Japan-Thursday 28 May 2020 [ AETOS Wire ]
(BUSINESS WIRE)-- Takeda Pharmaceutical Company Limited (TSE:4502/NYSE:TAK) today announced that the U.S. Food and Drug Administration (FDA) approved ALUNBRIG (brigatinib) for adult patients with anaplastic lymphoma kinase-positive (ALK+) metastatic non-small cell lung cancer (NSCLC) as detected by an FDA-approved test. This approval expands ALUNBRIG’s current indication to include the first-line setting. ALUNBRIG is a potent and selective next-generation tyrosine kinase inhibitor (TKI) designed to target ALK molecular alterations.
“We’re extremely proud of the positive results ALUNBRIG has shown for newly diagnosed ALK+ NSCLC patients, particularly those with brain metastases,” said Teresa Bitetti, President, Global Oncology Business Unit, Takeda. “Through a robust clinical development program and ongoing investigations across the NSCLC treatment landscape, Takeda is committed to uncovering solutions for people living with devastating forms of lung cancer in need of new options. We believe this approval for ALUNBRIG is a substantial step in the right direction and represents significant progress for Takeda’s broader lung cancer portfolio.”
The approval is based on results from the Phase 3 ALTA 1L trial, which is evaluating the safety and efficacy of ALUNBRIG compared to crizotinib in adult patients with ALK+ locally advanced or metastatic NSCLC who have not received prior treatment with an ALK inhibitor.
“Results from the ALTA 1L trial add brigatinib to the very short list of first-line treatment options for ALK+ lung cancer patients that have proven to be superior to crizotinib. Compared to crizotinib, brigatinib demonstrated superior efficacy, especially among those with brain metastases at baseline, and a low pill burden, at one pill a day, which is an important factor when we could be controlling disease for years,” said Ross Camidge, MD, PhD, Joyce Zeff Chair in Lung Cancer Research, University of Colorado Cancer Center. “These data have established brigatinib’s potential in the first-line setting, and I’m confident the FDA approval will open a new window of possibilities for physicians and their patients.”
After more than two years of follow-up, results from the ALTA 1L trial showed ALUNBRIG demonstrated superiority over crizotinib, with significant anti-tumor activity observed, especially in patients with baseline brain metastases.
ALUNBRIG reduced the risk of disease progression or death twofold compared with crizotinib (PFS hazard ratio = 0.49), with a 24-month median progression-free survival (PFS) as assessed by a blinded independent review committee (BIRC) versus 11 months for crizotinib.
ALUNBRIG demonstrated a confirmed overall response rate (ORR) of 74% (95% CI: 66–81) for ALUNBRIG and 62% (95% CI: 53–70) for crizotinib as assessed by a BIRC.
ALUNBRIG demonstrated a confirmed intracranial ORR for patients with measurable brain metastases at baseline of 78% (95% CI: 52–94) for patients treated with ALUNBRIG and 26% (95% CI: 10–48) for patients treated with crizotinib.
“As with many forms of lung cancer, ALK+ NSCLC is a complex and aggressive cancer that presents various treatment challenges for patients who are newly diagnosed, including those whose disease has spread to their brain,” said Andrea Stern Ferris, President and CEO, LUNGevity Foundation. “Having this option for newly diagnosed patients is exciting news for the ALK+ NSCLC community and adds to the remarkable progress we have witnessed in lung cancer treatment over the past decade.”
About the ALTA 1L Trial
The Phase 3 ALTA 1L (ALK in Lung Cancer Trial of BrigAtinib in 1st Line) trial of ALUNBRIG in adults is a global, ongoing, randomized, open-label, comparative, multicenter trial, which enrolled 275 patients (ALUNBRIG, n=137, crizotinib, n=138) with ALK+ locally advanced or metastatic NSCLC who have not received prior treatment with an ALK inhibitor. Patients received either ALUNBRIG, 180 mg orally once daily with seven-day lead-in at 90 mg once daily, or crizotinib, 250 mg orally twice daily.
The median age was 58 years in the ALUNBRIG arm and 60 years in the crizotinib arm. Twenty-nine percent of patients had brain metastases at baseline in the ALUNBRIG arm versus 30% in the crizotinib arm. Twenty-six percent of patients received prior chemotherapy for advanced or metastatic disease in the ALUNBRIG arm versus 27% in the crizotinib arm.
Blinded independent review committee (BIRC)-assessed progression-free survival (PFS) was the major efficacy outcome measure. Additional efficacy outcome measures included confirmed overall response rate (ORR) per RECIST v1.1 and intracranial ORR.
The warnings and precautions for ALUNBRIG are: interstitial lung disease (ILD)/pneumonitis, hypertension, bradycardia, visual disturbance, creatine phosphokinase (CPK) elevation, pancreatic enzyme elevation, hyperglycemia and embryo-fetal toxicity.
In the ALTA 1L trial, 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%).
The most common adverse reactions in the ALTA 1L trial (≥10%) with ALUNBRIG were diarrhea (53%), rash (40%), cough (35%), hypertension (32%), fatigue (32%), nausea (30%), myalgia (28%), dyspnea (25%), abdominal pain (24%), and headache (22%).
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 currently approved in more than 40 countries, including the U.S., Canada and the European Union (EU), for the treatment of people living with ALK+ metastatic NSCLC who have taken the medicine crizotinib, but their NSCLC has worsened or they cannot tolerate taking crizotinib. ALUNBRIG is also approved in the EU as a monotherapy for the treatment of adult patients with ALK+ advanced NSCLC previously not treated with an ALK inhibitor.
ALUNBRIG received Breakthrough Therapy Designation from the FDA for the treatment of patients with ALK+ NSCLC whose tumors are resistant to crizotinib and was granted Orphan Drug Designation by the FDA for the treatment of ALK+ NSCLC, ROS1+ and EGFR+ NSCLC.
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
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
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.
In ALTA 1L, 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%).
In ALTA, serious adverse reactions occurred in 38% of patients in the 90 mg group and 40% of patients in the 90→180 mg group. The most common serious adverse reactions were pneumonia (5.5% overall, 3.7% in the 90 mg group, and 7.3% in the 90→180 mg group) and ILD/pneumonitis (4.6% overall, 1.8% in the 90 mg group and 7.3% in the 90→180 mg group). Fatal adverse reactions occurred in 3.7% of patients and consisted of pneumonia (2 patients), sudden death, dyspnea, respiratory failure, pulmonary embolism, bacterial meningitis and urosepsis (1 patient each).
The most common adverse reactions (≥25%) with ALUNBRIG were diarrhea (49%), fatigue (39%), nausea (39%), rash (38%), cough (37%), myalgia (34%), headache (31%), hypertension (31%), vomiting (27%), and dyspnea (26%).
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.
