First-in-class AKT inhibitor has potential to reshape treatment for breast cancer patients with specific biomarker alterations (PIK3CA, AKT1 or PTEN).
Approval based on CAPItello-291 results which showed this combination reduced the risk of disease progression or death by 50% vs. Faslodex alone in the biomarker-altered population.
AstraZeneca’s Truqap (capivasertib) in combination with Faslodex (fulvestrant) has been approved in the US for the treatment of adult patients with hormone receptor (HR)-positive, HER2-negative locally advanced or metastatic breast cancer with one or more biomarker alterations (PIK3CA, AKT1 or PTEN). Eligible patients will have progressed on at least one endocrine-based regimen in the metastatic setting or experienced recurrence on or within 12 months of completing adjuvant therapy.
The approval by the Food and Drug Administration (FDA) was based on the results from the CAPItello-291 Phase III trial published earlier this year in The New England Journal of Medicine.1 In the trial, Truqap in combination with Faslodex reduced the risk of disease progression or death by 50% versus Faslodex alone in patients with tumours harbouring PI3K/AKT pathway biomarker alterations (based on hazard ratio of 0.50, 95% confidence interval 0.38-0.65; p=<0.001; median progression-free survival (PFS) 7.3 versus 3.1 months).
Breast cancer is the most common cancer and one of the leading causes of cancer-related death worldwide.2 HR-positive breast cancer (expressing estrogen or progesterone receptors, or both), is the most common subtype, with more than 65% of tumours considered HR-positive and HER2-low or HER2-negative.3 Collectively, mutations in PIK3CA, AKT1 and alterations in PTEN occur frequently, affecting up to 50% of patients with advanced HR-positive breast cancer.4-6 Endocrine therapies are widely used in this setting, but many patients develop resistance to 1st-line cyclin-dependent kinase (CDK) 4/6 inhibitors and estrogen receptor-targeting therapies, underscoring the need for additional endocrine therapy-based options.7
Komal Jhaveri, MD, Medical Oncologist, Memorial Sloan Kettering Cancer Center (MSK), US, said: “Patients with advanced HR-positive breast cancer typically experience tumour progression or resistance with widely used first-line endocrine therapies and there is an urgent need to extend the effectiveness of these approaches. The combination of capivasertib and fulvestrant, a first-of-its-kind combination, provides a much-needed new treatment option for up to half of patients in this setting with these specific biomarkers, offering the potential to delay disease progression and provide more time with their disease under control.”
Dave Fredrickson, Executive Vice President, Oncology Business Unit, AstraZeneca, said: “The rapid US approval of Truqap reinforces the important role of the PI3K/AKT pathway in HR-positive breast cancer and the critical need to test patients at the time of diagnosis, as up to fifty per cent have tumours with these alterations. As a first-in-class medicine, this approval provides a critical new option for patients in the US with this specific type of disease and we look forward to bringing Truqap to the many breast cancer patients who can benefit across the globe.”
In the CAPItello-291 trial, the safety profile of Truqap plus Faslodex was similar to that observed in previous trials evaluating this combination.1
Concurrently with this approval, the FDA also approved a companion diagnostic test to detect relevant alterations (PIK3CA, AKT1 and PTEN).
The US regulatory submission was granted Priority Review and reviewed under Project Orbis, which provides a framework for concurrent submission and review of oncology medicines among participating international partners. As part of Project Orbis, Truqap plus Faslodex is also under review by regulatory authorities in Australia, Brazil, Canada, Israel, Singapore, Switzerland and the UK.
Regulatory applications for Truqap in combination with Faslodex are also currently under review in China, the European Union, Japan and several other countries.
Financial considerations
Following this approval in the US, Astex Therapeutics is eligible to receive a milestone payment from AstraZeneca on first commercial sale of the drug in the US as well as royalties on future sales in line with the agreement between the two companies.
Notes
HR-positive breast cancer
Breast cancer is the most common cancer and one of the leading causes of cancer-related death worldwide.2 More than two million patients were diagnosed with breast cancer in 2020, with nearly 685,000 deaths globally.2 In the US, more than 290,000 patients are expected to be diagnosed in 2023, with more than 43,000 deaths.8
HR-positive breast cancer (expressing estrogen or progesterone receptors, or both), is the most common subtype of breast cancer with more than 65% of tumours considered HR-positive and HER2-low or HER2-negative.3 Collectively, mutations in PIK3CA, AKT1 and alterations in PTEN occur frequently, affecting up to 50% of patients with advanced HR-positive breast cancer.4-6
The growth of HR-positive breast cancer cells is often driven by estrogen receptors (ER), and endocrine therapies that target ER-driven disease are widely used as first-line treatment in the advanced setting, and often paired with CDK4/6 inhibitors.7,9,10 However, resistance to CDK4/6 inhibitors and current endocrine therapies develops in many patients with advanced disease.9 Once this occurs, treatment options are limited – with chemotherapy being the current standard of care – and survival rates are low with 30% of patients anticipated to live beyond five years after diagnosis.3,9,11
The optimisation of endocrine therapy and overcoming resistance to enable patients to continue benefiting from these treatments, as well as identifying new therapies for those who are less likely to benefit, are active areas of focus for breast cancer research.
CAPItello-291
CAPItello-291 is a Phase III, double-blind, randomised trial evaluating the efficacy of Truqap in combination with Faslodex versus placebo plus Faslodex for the treatment of locally advanced (inoperable) or metastatic HR-positive, HER2-low or negative (immunohistochemistry (IHC) 0 or 1+, or IHC 2+/in-situ hybridisation (ISH)-negative) breast cancer.
The global trial enrolled 708 adult patients with histologically confirmed HR-positive, HER2-low or negative breast cancer whose disease has recurred or progressed during or after aromatase inhibitor therapy, with or without a CDK4/6 inhibitor, and up to one line of chemotherapy for advanced disease. The trial has dual primary endpoints of PFS in the overall patient population and in a population of patients whose tumours have qualifying alterations in the PI3K/AKT pathway (PIK3CA, AKT1 or PTEN genes). In the trial, approximately 40% of tumours had these alterations and approximately 70% of patients received a prior CDK4/6 inhibitor.
Truqap
Truqap (capivasertib) is a first-in-class, potent, adenosine triphosphate (ATP)-competitive inhibitor of all three AKT isoforms (AKT1/2/3). Truqap 400mg is administered twice daily according to an intermittent dosing schedule of four days on and three days off. This was chosen in early phase trials based on tolerability and the degree of target inhibition.
Truqap is currently being evaluated in Phase III trials for the treatment of multiple subtypes of breast cancer and in other tumour types either as monotherapy or in combination with established treatments. The ongoing clinical research programme is focused on tumours reliant on signalling via the PI3K/AKT pathway, and in tumours harbouring biomarker alterations in this pathway.
Truqap was discovered by AstraZeneca subsequent to a collaboration with Astex Therapeutics (and its collaboration with the Institute of Cancer Research and Cancer Research Technology Limited).
Faslodex
Faslodex is an endocrine therapy indicated for the treatment of estrogen receptor-positive, locally advanced or metastatic breast cancer in postmenopausal women not previously treated with endocrine therapy, or with disease relapse on or after adjuvant anti-estrogen therapy, or disease progression on anti-estrogen therapy.
In the US, EU and Japan, Faslodex is also approved in combination with CDK4/6 inhibitors for the treatment of women with HR-positive, HER2-negative advanced or metastatic breast cancer, whose cancer has progressed after endocrine medicine. Faslodex represents a hormonal treatment approach that helps to slow tumour growth by blocking and degrading the estrogen receptor – a key driver of disease progression.
Faslodex is approved as monotherapy or in combination with medicines from various drug classes including CDK4/6, PI3K and AKT inhibitors for the treatment of patients with HR-positive advanced breast cancer and is being evaluated in combination with medicines from other drug classes.
AstraZeneca in breast cancer
Driven by a growing understanding of breast cancer biology, AstraZeneca is starting to challenge, and redefine, the current clinical paradigm for how breast cancer is classified and treated to deliver even more effective treatments to patients in need – with the bold ambition to one day eliminate breast cancer as a cause of death.
AstraZeneca has a comprehensive portfolio of approved and promising compounds in development that leverage different mechanisms of action to address the biologically diverse breast cancer tumour environment.
With Enhertu (trastuzumab deruxtecan), a HER2-directed antibody drug conjugate (ADC), AstraZeneca and Daiichi Sankyo are aiming to improve outcomes in previously treated HER2-positive and HER2-low metastatic breast cancer and are exploring its potential in earlier lines of treatment and in new breast cancer settings.
In HR-positive breast cancer, AstraZeneca continues to improve outcomes with foundational medicines Faslodex and Zoladex (goserelin) and aims to reshape the HR-positive space with first-in-class AKT inhibitor, Truqap, and next-generation SERD and potential new medicine camizestrant. AstraZeneca is also collaborating with Daiichi Sankyo to explore the potential of TROP2-directed ADC, datopotamab deruxtecan, in this setting.
PARP inhibitor Lynparza (olaparib) is a targeted treatment option that has been studied in early and metastatic breast cancer patients with an inherited BRCA mutation. AstraZeneca with MSD (Merck & Co., Inc. in the US and Canada) continue to research Lynparza in these settings and to explore its potential in earlier disease.
To bring much-needed treatment options to patients with triple-negative breast cancer, an aggressive form of breast cancer, AstraZeneca is evaluating the potential of datopotamab deruxtecan alone and in combination with immunotherapy Imfinzi (durvalumab), Truqap in combination with chemotherapy, and Imfinzi in combination with other oncology medicines, including Lynparza and Enhertu.

Bristol Myers Squibb (NYSE: BMY) recently announced that Opdivo®(nivolumab) was approved by the U.S. Food and Drug Administration (FDA) for the adjuvant treatment of adult and pediatric patients 12 years and older with completely resected stage IIB or IIC melanoma, expanding upon the existing adjuvant indication for Opdivo and further reinforcing the company’s legacy of providing treatment options for melanoma patients.1 The approval is based on the Phase 3 CheckMate -76K trial, which compared Opdivo (n=526) to placebo (n=264).1,2
In the trial, Opdivo reduced the risk of recurrence, new primary melanoma, or death in patients with completely resected stage IIB or IIC melanoma by 58% compared to placebo (Hazard Ratio [HR] 0.42; 95% Confidence Interval [CI]: 0.30-0.59; P<0.0001).1 At one year, the recurrence-free survival (RFS) rate was 89% (95% CI: 86-92) for Opdivo versus 79% (95% CI: 74-84) for placebo.3 Additionally, in a pre-specified, exploratory subgroup analysis, the RFS unstratified HR was 0.34 (95% CI: 0.20-0.56) in patients with stage IIB melanoma, and 0.51 (95% CI: 0.32-0.81) in stage IIC melanoma patients.3 One-year RFS rates by stage for patients who received Opdivo were 93% (95% CI: 89–95) in stage IIB versus 84% (95% CI: 77–89) with placebo, and 84% (95% CI: 78–88) in stage IIC versus 72% (95% CI: 62–80) with placebo.3
Opdivo is associated with the following Warnings & Precautions: severe and fatal immune-mediated adverse reactions, including pneumonitis, colitis, hepatitis and hepatotoxicity, endocrinopathies, dermatologic adverse reactions, nephritis with renal dysfunction, other immune-mediated adverse reactions; infusion-related reactions; complications of allogeneic hematopoietic stem cell transplantation (HSCT); embryo-fetal toxicity; and increased mortality in patients with multiple myeloma when Opdivo is added to a thalidomide analogue and dexamethasone, which is not recommended outside of controlled clinical trials.1 Please see Important Safety Information below.
The FDA previously approved Opdivo for the adjuvant treatment of adult and pediatric patients 12 years and older with melanoma with involvement of lymph nodes or metastatic disease who have undergone complete resection, based upon data from the CheckMate -238 trial.1
Additional CheckMate -76K follow-up data will be presented at the Society for Melanoma Research Annual Meeting in November.
INDICATION
OPDIVO® is indicated for the adjuvant treatment of adult and pediatric patients 12 years and older with completely resected Stage IIB, Stage IIC, Stage III, or Stage IV melanoma.
IMPORTANT SAFETY INFORMATION
Severe and Fatal Immune-Mediated Adverse Reactions
Immune-mediated adverse reactions listed herein may not include all possible severe and fatal immune-mediated adverse reactions.
Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. While immune-mediated adverse reactions usually manifest during treatment, they can also occur after discontinuation of OPDIVO. Early identification and management are essential to ensure safe use of OPDIVO. Monitor for signs and symptoms that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate clinical chemistries including liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment with OPDIVO. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.
Withhold or permanently discontinue OPDIVO depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information). In general, if OPDIVO interruption or discontinuation is required, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy. Toxicity management guidelines for adverse reactions that do not necessarily require systemic steroids (e.g., endocrinopathies and dermatologic reactions) are discussed below.
Immune-Mediated Pneumonitis
OPDIVO can cause immune-mediated pneumonitis. The incidence of pneumonitis is higher in patients who have received prior thoracic radiation. In patients receiving OPDIVO monotherapy, immune-mediated pneumonitis occurred in 3.1% (61/1994) of patients, including Grade 4 (<0.1%), Grade 3 (0.9%), and Grade 2 (2.1%).
Immune-Mediated Colitis
OPDIVO can cause immune-mediated colitis. A common symptom included in the definition of colitis was diarrhea. Cytomegalovirus (CMV) infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. In patients receiving OPDIVO monotherapy, immune-mediated colitis occurred in 2.9% (58/1994) of patients, including Grade 3 (1.7%) and Grade 2 (1%).
Immune-Mediated Hepatitis and Hepatotoxicity
OPDIVO can cause immune-mediated hepatitis. In patients receiving OPDIVO monotherapy, immune-mediated hepatitis occurred in 1.8% (35/1994) of patients, including Grade 4 (0.2%), Grade 3 (1.3%), and Grade 2 (0.4%).
Immune-Mediated Endocrinopathies
OPDIVO can cause primary or secondary adrenal insufficiency, immune-mediated hypophysitis, immune-mediated thyroid disorders, and Type 1 diabetes mellitus, which can present with diabetic ketoacidosis. Withhold OPDIVO depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information). For Grade 2 or higher adrenal insufficiency, initiate symptomatic treatment, including hormone replacement as clinically indicated. Hypophysitis can present with acute symptoms associated with mass effect such as headache, photophobia, or visual field defects. Hypophysitis can cause hypopituitarism; initiate hormone replacement as clinically indicated. Thyroiditis can present with or without endocrinopathy.
Hypothyroidism can follow hyperthyroidism; initiate hormone replacement or medical management as clinically indicated. Monitor patients for hyperglycemia or other signs and symptoms of diabetes; initiate treatment with insulin as clinically indicated.
In patients receiving OPDIVO monotherapy, adrenal insufficiency occurred in 1% (20/1994), including Grade 3 (0.4%) and Grade 2 (0.6%).
In patients receiving OPDIVO monotherapy, hypophysitis occurred in 0.6% (12/1994) of patients, including Grade 3 (0.2%) and Grade 2 (0.3%).
In patients receiving OPDIVO monotherapy, thyroiditis occurred in 0.6% (12/1994) of patients, including Grade 2 (0.2%).
In patients receiving OPDIVO monotherapy, hyperthyroidism occurred in 2.7% (54/1994) of patients, including Grade 3 (<0.1%) and Grade 2 (1.2%).
In patients receiving OPDIVO monotherapy, hypothyroidism occurred in 8% (163/1994) of patients, including Grade 3 (0.2%) and Grade 2 (4.8%).
In patients receiving OPDIVO monotherapy, diabetes occurred in 0.9% (17/1994) of patients, including Grade 3 (0.4%) and Grade 2 (0.3%), and 2 cases of diabetic ketoacidosis.
Immune-Mediated Nephritis with Renal Dysfunction
OPDIVO can cause immune-mediated nephritis. In patients receiving OPDIVO monotherapy, immune-mediated nephritis and renal dysfunction occurred in 1.2% (23/1994) of patients, including Grade 4 (<0.1%), Grade 3 (0.5%), and Grade 2 (0.6%).
Immune-Mediated Dermatologic Adverse Reactions
OPDIVO can cause immune-mediated rash or dermatitis. Exfoliative dermatitis, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug rash with eosinophilia and systemic symptoms (DRESS) has occurred with PD-1/PD-L1 blocking antibodies. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate nonexfoliative rashes.
Withhold or permanently discontinue OPDIVO depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information).
In patients receiving OPDIVO monotherapy, immune-mediated rash occurred in 9% (171/1994) of patients, including Grade 3 (1.1%) and Grade 2 (2.2%).
Other Immune-Mediated Adverse Reactions
The following clinically significant immune-mediated adverse reactions occurred at an incidence of <1% (unless otherwise noted) in patients who received OPDIVO monotherapy or were reported with the use of other PD-1/PD-L1 blocking antibodies. Severe or fatal cases have been reported for some of these adverse reactions: cardiac/vascular: myocarditis, pericarditis, vasculitis; nervous system: meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barré syndrome, nerve paresis, autoimmune neuropathy; ocular: uveitis, iritis, and other ocular inflammatory toxicities can occur; gastrointestinal: pancreatitis to include increases in serum amylase and lipase levels, gastritis, duodenitis; musculoskeletal and connective tissue: myositis/polymyositis, rhabdomyolysis, and associated sequelae including renal failure, arthritis, polymyalgia rheumatica; endocrine: hypoparathyroidism; other (hematologic/immune): hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis (HLH), systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection.
Some ocular IMAR cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada–like syndrome, which has been observed in patients receiving OPDIVO, as this may require treatment with systemic corticosteroids to reduce the risk of permanent vision loss.
Infusion-Related Reactions
OPDIVO can cause severe infusion-related reactions. Discontinue OPDIVO in patients with severe (Grade 3) or life-threatening (Grade 4) infusion-related reactions. Interrupt or slow the rate of infusion in patients with mild (Grade 1) or moderate (Grade 2) infusion-related reactions. In patients receiving OPDIVO monotherapy as a 60-minute infusion, infusion-related reactions occurred in 6.4% (127/1994) of patients. In a separate trial in which patients received OPDIVO monotherapy as a 60-minute infusion or a 30-minute infusion, infusion-related reactions occurred in 2.2% (8/368) and 2.7% (10/369) of patients, respectively. Additionally, 0.5% (2/368) and 1.4% (5/369) of patients, respectively, experienced adverse reactions within 48 hours of infusion that led to dose delay, permanent discontinuation or withholding of OPDIVO.
Complications of Allogeneic Hematopoietic Stem Cell Transplantation
Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with OPDIVO. Transplant-related complications include hyperacute graft-versus-host-disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between OPDIVO and allogeneic HSCT.
Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with OPDIVO prior to or after an allogeneic HSCT.
Embryo-Fetal Toxicity
Based on its mechanism of action and findings from animal studies, OPDIVO can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with OPDIVO and for at least 5 months after the last dose.
Increased Mortality in Patients with Multiple Myeloma when OPDIVO is Added to a Thalidomide Analogue and Dexamethasone
In randomized clinical trials in patients with multiple myeloma, the addition of OPDIVO to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of patients with multiple myeloma with a PD-1 or PD-L1 blocking antibody in combination with a thalidomide analogue plus dexamethasone is not recommended outside of controlled clinical trials.
Lactation
There are no data on the presence of OPDIVO in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in breastfed children, advise women not to breastfeed during treatment and for 5 months after the last dose.
Serious Adverse Reactions
In Checkmate 76K, serious adverse reactions occurred in 18% of patients receiving OPDIVO (n=524). Adverse reactions which resulted in permanent discontinuation of OPDIVO in >1% of patients included arthralgia (1.7%), rash (1.7%), and diarrhea (1.1%). A fatal adverse reaction occurred in 1 (0.2%) patient (heart failure and acute kidney injury). The most frequent Grade 3-4 lab abnormalities reported in ≥1% of OPDIVO-treated patients were increased lipase (2.9%), increased AST (2.2%), increased ALT (2.1%), lymphopenia (1.1%), and decreased potassium (1.0%).
Common Adverse Reactions
In Checkmate -76K, the most common adverse reactions (≥20%) reported with OPDIVO (n=524) were fatigue (36%), musculoskeletal pain (30%), rash (28%) diarrhea (23%) and pruritis (20%).
Please see US Full Prescribing Information for OPDIVO.

Takeda has announced that following discussions with the U.S. Food and Drug Administration (FDA), we will begin the process of voluntarily withdrawing EXKIVITY (mobocertinib) from the U.S. market over the next few months. EXKIVITY is currently indicated for adult patients with epidermal growth factor receptor (EGFR) Exon20 insertion mutation-positive (insertion+) locally advanced or metastatic non-small cell lung cancer (mNSCLC) whose disease has progressed on or after platinum-based chemotherapy. For the U.S. Prescribing Information, including the Boxed Warning, please visit www.exkivity-update.com/prescribing-information.
This decision to voluntarily withdraw EXKIVITY was based on the outcome of the Phase 3 EXCLAIM-2 confirmatory trial, which did not meet its primary endpoint and thus did not fulfill the confirmatory data requirements of the Accelerated Approval granted by the U.S. FDA. The EXCLAIM-2 trial was a Phase 3, multicenter, open-label study designed to investigate the safety and efficacy of EXKIVITY as a monotherapy versus platinum-based chemotherapy in first-line EGFR Exon20 insertion+ locally advanced or mNSCLC. No new safety signals were observed in the EXCLAIM-2 trial. Full data from the trial will be presented at an upcoming medical meeting and published in a peer-reviewed journal.
EXKIVITY remains available to prescribe while Takeda works with the FDA on withdrawal timing. Takeda will provide updates as appropriate to keep you informed. Updates will also be posted on www.exkivity-update.com. Takeda has shared a similar communication with healthcare providers that have prescribed EXKIVITY.
Takeda is committed to ensuring that patients receiving EXKIVITY can maintain access when EXKIVTIY is withdrawn. For additional questions, please contact Takeda at 844-662-8532 or globaloncologymedinfo@takeda.com.

§ Full Prescribing Information Including Boxed Warning and Medication Guide
AstraZeneca recently announced that new data from the ADAURA trial regarding AGRISSO® (osimertinib) has been released.
The ADAURA trial is an ongoing study of TAGRISSO as adjuvant therapy after tumor resection in adult patients with completely resected Stage IB-IIIA EGFRm (exon 19 deletions or exon 21 L858R mutations) non-small cell lung cancer (NSCLC).
TAGRISSO was approved as adjuvant therapy after tumor resection in adult patients with non-small cell lung cancer (NSCLC) whose tumors have epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 L858R mutations, as detected by an FDA-approved test on December 18, 2020.
Please see the Important Safety Information below and full Prescribing Information, including Patient Information.
IMPORTANT SAFETY INFORMATION
∙ There are no contraindications for TAGRISSO
∙ Interstitial lung disease (ILD)/pneumonitis occurred in 3.7% of the 1479 TAGRISSO-treated patients; 0.3% of cases were fatal. Withhold TAGRISSO and promptly investigate for ILD in patients who present with worsening of respiratory symptoms which may be indicative of ILD (eg, dyspnea, cough and fever). Permanently discontinue TAGRISSO if ILD is confirmed
∙ Heart rate-corrected QT (QTc) interval prolongation occurs in TAGRISSO-treated patients. Of the 1479 TAGRISSO-treated patients in clinical trials, 0.8% were found to have a QTc >500 msec, and 3.1% of patients had an increase from baseline QTc >60 msec. No QTc-related arrhythmias were reported. Conduct periodic monitoring with ECGs and electrolytes in patients with congenital long QTc syndrome, congestive heart failure, electrolyte abnormalities, or those who are taking medications known to prolong the QTc interval. Permanently discontinue TAGRISSO in patients who develop QTc interval prolongation with signs/symptoms of life-threatening arrhythmia
∙ Cardiomyopathy occurred in 3% of the 1479 TAGRISSO-treated patients; 0.1% of cardiomyopathy cases were fatal. A decline in left ventricular ejection fraction (LVEF) ≥10% from baseline and to <50% LVEF occurred in 3.2% of 1233 patients who had baseline and at least one follow-up LVEF assessment. In the ADAURA study, 1.5% (5/325) of TAGRISSO-treated patients experienced LVEF decreases ≥10% from baseline and a drop to <50%. Conduct cardiac monitoring, including assessment of LVEF at baseline and during treatment, in patients with cardiac risk factors. Assess LVEF in patients who develop relevant cardiac signs or symptoms during treatment. For symptomatic congestive heart failure, permanently discontinue TAGRISSO
∙ Keratitis was reported in 0.7% of 1479 patients treated with TAGRISSO in clinical trials. Promptly refer patients with signs and symptoms suggestive of keratitis (such as eye inflammation, lacrimation, light sensitivity, blurred vision, eye pain and/or red eye) to an ophthalmologist
∙ Postmarketing cases consistent with Stevens-Johnson syndrome (SJS) and erythema multiforme major (EMM) have been reported in patients receiving TAGRISSO. Withhold TAGRISSO if SJS or EMM is suspected and permanently discontinue if confirmed
∙ Postmarketing cases of cutaneous vasculitis including leukocytoclastic vasculitis, urticarial vasculitis, and IgA vasculitis have been reported in patients receiving TAGRISSO. Withhold TAGRISSO if cutaneous vasculitis is suspected, evaluate for systemic involvement, and consider dermatology consultation. If no other etiology can be identified, consider permanent discontinuation of TAGRISSO based on severity
∙ Aplastic anemia has been reported in patients treated with TAGRISSO in clinical trials (0.07% of 1479) and postmarketing. Some cases had a fatal outcome. Inform patients of the signs and symptoms of aplastic anemia including but not limited to, new or persistent fevers, bruising, bleeding, and pallor.

Seagen Announces FDA Accelerated Approval of TUKYSA® (tucatinib) in Combination with Trastuzumab for People with Previously Treated RAS Wild-Type, HER2-Positive Metastatic Colorectal Cancer
– First FDA-approved treatment in HER2-positive metastatic colorectal cancer –
– Combination regimen is approved for use in the second-line treatment setting and beyond –
BOTHELL, Wash.–(BUSINESS WIRE)– Seagen Inc. (Nasdaq: SGEN) today announced that the U.S. Food and Drug Administration (FDA) has granted accelerated approval to TUKYSA® (tucatinib) in combination with trastuzumab for adult patients with RASwild-type, HER2-positive unresectable or metastatic colorectal cancer that has progressed following treatment with fluoropyrimidine-, oxaliplatin- and irinotecan-based chemotherapy. TUKYSA is approved under the FDA’s Accelerated Approval Program based on tumor response rate and durability of response from the phase 2 MOUNTAINEER clinical trial. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials. This is the first FDA-approved treatment in HER2-positive metastatic colorectal cancer. The FDA previously granted Breakthrough Therapy Designation and Priority Review for TUKYSA in this setting.
“Historically, patients with HER2-positive metastatic colorectal cancer who have progressed following frontline therapy have had poor outcomes,” said John Strickler, M.D., associate professor of medicine, Duke University Medical Center, and lead investigator for the MOUNTAINEER trial. “The FDA approval of a chemotherapy-free combination regimen that specifically targets HER2 is great news for these patients.”
“Biomarker testing is bringing new hope to people living with some types of colorectal cancer by opening the door to targeted treatments like TUKYSA for those who have RAS wild-type, HER2-positive disease,” said Michael Sapienza, CEO, Colorectal Cancer Alliance. “It is critical that physicians and patients understand the importance of comprehensive biomarker testing at diagnosis because it can inform treatment decisions and help improve outcomes.”
Results from the MOUNTAINEER trial showed a 38% overall response rate (ORR) (95% Confidence Interval [CI]: 28, 49) per blinded independent central review (BICR) in the patients who received TUKYSA in combination with trastuzumab (N=84 with a median age of 55.0 years [range: 24 to 77]). Complete responses were observed in 3.6% of patients (n=3), and partial responses were observed in 35% of patients (n=29). The median duration of response (DOR) per BICR was 12.4 months (95% CI: 8.5, 20.5). At study entry, 64% and 70% of these patients had liver or lung metastases, respectively.
The Prescribing Information for TUKYSA includes warnings and precautions for diarrhea, hepatotoxicity and embryo-fetal toxicity, some of which may be severe or fatal. In MOUNTAINEER, serious adverse reactions occurred in 22% of patients; the most common (in ≥2% of patients) were intestinal obstruction (7%), urinary tract infection (3.5%), pneumonia, abdominal pain and rectal perforation (2.3% each). The most common adverse reactions (≥20%) in patients treated with TUKYSA and trastuzumab were diarrhea, fatigue, rash, nausea, abdominal pain, infusion-related reactions and pyrexia. Adverse reactions leading to permanent discontinuation of TUKYSA occurred in 6% of patients; the most common (in ≥2% of patients) was increased alanine aminotransferase (ALT) (2.3%). Please see additional Important Safety Information below.
“The accelerated approval of TUKYSA for RAS wild-type, HER2-positive metastatic colorectal cancer expands TUKYSA-based therapy to patients across two distinct types of cancer,” said Marjorie Green, M.D., Senior Vice President and Head of Late-Stage Development, Seagen. “We believe the efficacy and safety profile of the TUKYSA and trastuzumab-based regimen further establishes its role as an important backbone of dual HER2 inhibition in the treatment of adult patients with certain HER2-expressing breast and colorectal cancers.”
The FDA’s Accelerated Approval Program allows for approval of a medicine based on a surrogate endpoint that is reasonably likely to predict clinical benefit if the medicine fills an unmet medical need for a serious condition. A global, randomized phase 3 clinical trial (MOUNTAINEER-03) is ongoing and will compare TUKYSA in combination with trastuzumab and mFOLFOX6 with standard of care, which is intended to serve as a confirmatory trial and potentially support future global regulatory submissions. Merck, known as MSD outside of the U.S. and Canada, is commercializing TUKYSA in regions outside of the U.S., Canada and Europe and plans to discuss results from the MOUNTAINEER trial with certain health authorities as it continues to accelerate the filing of TUKYSA in its territories.

Merck announces new treatment indication for KEYTRUDA®
Adjuvant Treatment Following Resection and Platinum-Based Chemotherapy for Adult Patients With Stage IB (T2a ≥4 cm), II, or IIIA NSCLC KEYTRUDA® (pembrolizumab) Injection 100 mg, as a single agent, is indicated for adjuvant treatment following resection and platinum-based chemotherapy for adult patients with stage IB (T2a ≥4 cm), II, or IIIA non–small cell lung cancer (NSCLC).
• KEYTRUDA is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death receptor-1 (PD-1) or the programmed death ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, can affect more than one body system simultaneously, and can occur at any time after starting treatment or after discontinuation of treatment. Important immune-mediated adverse reactions listed here may not include all possible severe and fatal immune-mediated adverse reactions.
• Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Early identification and management are essential to ensure safe use of anti–PD-1/PD-L1 treatments. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.
• Withhold or permanently discontinue KEYTRUDA depending on severity of the immune-mediated adverse reaction. In general, if KEYTRUDA requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose adverse reactions are not controlled with corticosteroid therapy. Immune-Mediated Pneumonitis.
Before prescribing KEYTRUDA® (pembrolizumab), please read the Prescribing Information.
