IMFINZI? (durvalumab) US label updated with overall survival data in unresectable, Stage III non-small cell lung cancer

[caption id="attachment_9277" align="aligncenter" width="747"]Press Release Press Release[/caption] IMFINZI is the only immunotherapy approved to treat patients in this curative-intent setting following chemoradiation therapy AstraZeneca today announced that the US Food and Drug Administration (FDA) has approved the inclusion of overall survival (OS) data from the Phase III PACIFIC trial in an update to the IMFINZI??(durvalumab) US Prescribing Information for patients with unresectable, Stage III non-small cell lung cancer (NSCLC) whose disease has not progressed following concurrent platinum-based chemotherapy and radiation therapy (CRT). The label update was based on results from the primary OS analysis published in?The New England Journal of Medicine?in September 2018 which demonstrated a significant and clinically-proven OS benefit for treatment with IMFINZI vs placebo in this setting, reducing the risk of death by 32% (HR 0.68, 95% CI, 0.53-0.87;?P=0.0025). In a follow-up three-year post-hoc OS analysis presented at the 2019 ASCO Annual Meeting, results for IMFINZI remained consistent with the two-year data showing a 31% reduction in the risk of death vs placebo (HR 0.69, 95% CI 0.55-0.86) and showing that 57% (95% CI 52.3-61.4) of patients on IMFINZI were still alive vs 44% (95% CI 37.0-49.9) of patients on placebo. Olivier Nataf, Head of US Oncology, said, ?This label update coupled with the recent three-year overall survival data continue to reinforce the PACIFIC regimen as the standard of care in this curative-intent setting. For patients and providers, this announcement provides further evidence and confidence in the survival benefit of IMFINZI.? IMFINZI is approved for the treatment of unresectable, Stage III non-small cell lung cancer in more than 45 countries, including the US, EU and Japan, based on the Phase III PACIFIC trial. Since the first approval in February 2018, over 20,000 patients have been treated with IMFINZI in this setting. The National Comprehensive Cancer Network clinical practice guidelines in oncology (NCCN Guidelines?) recommend durvalumab (IMFINZI) as the only Category 1 post-CRT consolidation immunotherapy for unresectable, Stage III NSCLC patients.1,2 IMFINZI can cause serious, potentially fatal adverse events (AEs). In the previous two-year OS analysis, the most common adverse reactions (greater than or equal to 20% of patients) for patients receiving IMFINZI versus placebo were cough (35.2% vs 25.2%), fatigue (24.0% vs 20.5%), dyspnea (22.3% vs 23.9%) and radiation pneumonitis (20.2% vs 15.8%). 30.5% of patients experienced a grade 3 or 4 AE with IMFINZI vs 26.1% with placebo, and 15.4% of patients discontinued treatment due to AEs with IMFINZI vs 9.8% of patients on placebo. IMPORTANT SAFETY INFORMATION There are no contraindications for?IMFINZI??(durvalumab). IMFINZI can cause serious, potentially fatal adverse reactions including?immune-mediated?pneumonitis, hepatitis, colitis or diarrhea, endocrinopathies, nephritis, rash or dermatitis, other?immune-mediated?adverse reactions, infection, and infusion-related reactions. Please refer to the full Prescribing Information for important dosage modification and management information specific to adverse reactions. Immune-Mediated?Pneumonitis IMFINZI can cause immune-mediated pneumonitis, defined as requiring use of corticosteroids. Fatal cases have been reported.

In clinical studies enrolling 1889 patients with various cancers?who received IMFINZI,?colitis or diarrhea occurred in 18% of patients, including Grade 3 (1.0%) and Grade 4 (0.1%) colitis. Diarrhea or colitis led to discontinuation of IMFINZI in 0.4% of the 1889 patients. Immune-Mediated?Endocrinopathies IMFINZI can cause immune-mediated endocrinopathies, including thyroid disorders, adrenal insufficiency, type 1 diabetes mellitus, and hypophysitis/hypopituitarism.?Monitor patients for clinical signs and symptoms of endocrinopathies.
  • Thyroid disorders?Monitor thyroid function prior to and periodically during treatment. Initiate hormone replacement therapy or medical management of hyperthyroidism as clinically indicated. Withhold IMFINZI for Grades 2?4 hyperthyroidism, until clinically stable. Continue IMFINZI for hypothyroidism. In clinical studies enrolling 1889 patients with various cancers who received IMFINZI,?hypothyroidism occurred in 11% of patients, while hyperthyroidism occurred in 7% of patients. Thyroiditis occurred in 0.9% of patients, including Grade 3 (<0.1%). Hypothyroidism was preceded by thyroiditis or hyperthyroidism in 25% of patients.
  • Adrenal insufficiency?Administer corticosteroids as clinically indicated and withhold IMFINZI until clinically stable for Grade 2 or higher adrenal insufficiency. In clinical studies enrolling 1889 patients with various cancers who received IMFINZI, adrenal insufficiency occurred in 0.7% of patients, including Grade 3 (<0.1%) adrenal insufficiency.
  • Type 1 diabetes mellitus?Initiate treatment with insulin as clinically indicated. Withhold IMFINZI for Grades 2?4 type 1 diabetes mellitus, until clinically stable. In clinical studies enrolling 1889 patients with various cancers who received IMFINZI, type 1 diabetes mellitus occurred in <0.1% of patients.
  • Hypophysitis?Administer corticosteroids and hormone replacement as clinically indicated and withhold IMFINZI until clinically stable for Grade 2 or higher hypophysitis. Hypopituitarism leading to adrenal insufficiency and diabetes insipidus occurred in <0.1% of 1889 patients with various cancers who received IMFINZI.
Immune-Mediated Nephritis IMFINZI can cause immune-mediated nephritis, defined as evidence of renal dysfunction requiring use of corticosteroids. Fatal cases have occurred. Monitor patients for abnormal renal function tests prior to and periodically during treatment with IMFINZI. Administer corticosteroids as clinically indicated. Withhold IMFINZI for creatinine greater than 1.5 to 3 times the ULN; permanently discontinue IMFINZI and administer corticosteroids in patients with creatinine greater than 3 times the ULN. In clinical studies enrolling 1889 patients with various cancers who received IMFINZI,?nephritis (reported as any of the following: increased creatinine or urea, acute kidney injury, renal failure, decreased glomerular filtration rate, tubulointerstitial nephritis, decreased creatinine clearance, glomerulonephritis, and nephritis) occurred in 6.3% of the patients including Grade 3 (1.1%), Grade 4 (0.2%), and Grade 5 (0.1%) nephritis. IMFINZI was discontinued in 0.3% of the 1889 patients. Immune-Mediated Dermatologic Reactions IMFINZI can cause immune-mediated rash. Bullous dermatitis and Stevens Johnson Syndrome (SJS)/toxic epidermal necrolysis (TEN) have occurred with other products in this class. Administer corticosteroids for Grade 2 rash or dermatitis lasting for more than 1 week or for Grade 3 or 4 rash or dermatitis. Withhold IMFINZI for Grade 2 rash or dermatitis lasting longer than 1 week or Grade 3 rash or dermatitis; permanently discontinue IMFINZI in patients with Grade 4 rash or dermatitis. In clinical studies enrolling 1889 patients with various cancers who received IMFINZI, 26% of patients developed rash or dermatitis and 0.4% of the patients developed vitiligo. Rash or dermatitis led to discontinuation of IMFINZI in 0.1% of the 1889 patients. Other?Immune-Mediated?Adverse Reactions IMFINZI can cause severe and fatal immune-mediated adverse reactions. These immune-mediated reactions may involve any organ system. While immune-mediated reactions usually manifest during treatment with IMFINZI, immune-mediated adverse reactions can also manifest after discontinuation of IMFINZI. For suspected immune-mediated adverse reactions, exclude other causes and initiate corticosteroids as clinically indicated. Withhold IMFINZI for Grade 3 immune-mediated adverse reactions, unless clinical judgment indicates discontinuation; permanently discontinue IMFINZI for Grade 4 adverse reactions. The following clinically significant, immune-mediated adverse reactions occurred at an incidence of less than 1% each in 1889 patients who received IMFINZI: aseptic meningitis, hemolytic anemia, immune thrombocytopenic purpura, myocarditis, myositis, and ocular inflammatory toxicity, including uveitis and keratitis. Additional clinically significant immune-mediated adverse reactions have been seen with other products in this class (see Warnings and Precautions Section 5.7 of IMFINZI full Prescribing Information). Infection IMFINZI can cause serious infections, including fatal cases. Monitor patients for signs and symptoms of infection and treat as clinically indicated. Withhold IMFINZI for Grade 3 or 4 infection, until clinically stable. In clinical studies enrolling 1889 patients with various cancers who received IMFINZI, infections occurred in 43% of patients, including Grade 3 (8%), Grade 4 (1.9%), and Grade 5 (1.0%). In patients with Stage III NSCLC in the PACIFIC study, the most common Grade 3 or higher infection was pneumonia, which occurred in 5% of patients. Infusion-Related Reactions IMFINZI can cause severe or life-threatening infusion-related reactions. Monitor patients for signs and symptoms of an infusion-related reaction. Interrupt or slow the rate of infusion for Grades 1?2 infusion-related reactions; permanently discontinue for Grades 3?4 infusion-related reactions. In clinical studies enrolling 1889 patients with various cancers who received IMFINZI, infusion-related reactions occurred in 2.2% of patients, including Grade 3 (0.3%). Embryo-Fetal Toxicity Based on its mechanism of action and data from animal studies, IMFINZI can cause fetal harm when administered to a pregnant woman. There are no data on the use of IMFINZI in pregnant women. Advise pregnant women of the potential risk to a fetus and advise women of reproductive potential to use effective contraception during treatment and for at least 3 months after the last dose of IMFINZI. Lactation There is no information regarding the presence of IMFINZI in human milk; however, because of the potential for adverse reactions in breastfed infants from IMFINZI, advise women not to breastfeed during treatment and for at least 3 months after the last dose.

NOTES TO EDITORS

About PACIFIC The PACIFIC trial is a Phase III, randomized, double-blinded, placebo-controlled, multi-center trial of IMFINZI??(durvalumab) as treatment in ?all-comer? patients (ie, regardless of PD-L1 status) with unresectable Stage III NSCLC whose disease has not progressed following platinum-based chemotherapy concurrent with radiation therapy (CRT). The trial is being conducted in 235 centers across 26 countries involving 713 patients. The primary endpoints of the trial are progression-free survival (PFS) and overall survival (OS), and secondary endpoints include landmark PFS and OS, overall response rate (ORR) and duration of response (DoR). About Stage III NSCLC Stage III (locally advanced) non-small cell lung cancer (NSCLC) is commonly divided into three sub-categories (IIIA, IIIB and IIIC), defined by how much the cancer has spread locally and the possibility of surgery. Stage III disease is different from Stage IV disease, when the cancer has spread (metastasized) to distant organs, as Stage III is currently treated with curative intent. Approximately one in four patients with NSCLC in the United States present with Stage III disease, which is estimated to affect over 43,000 patients. The majority of Stage III NSCLC patients are diagnosed with unresectable tumors. Until recently, the standard of care beyond CRT was active surveillance to monitor for progression as there had been no FDA approved treatments following CRT. About IMFINZI??(durvalumab) IMFINZI??(durvalumab) is a human monoclonal antibody that binds to PD-L1 and blocks the interaction of PD-L1 with PD-1 and CD80, countering the tumor's immune-evading tactics and releasing the inhibition of immune responses. IMFINZI?is approved for unresectable, Stage III NSCLC in more than 45 countries including the US, EU and Japan based on the Phase III PACIFIC trial. As part of a broad development program, IMFINZI?is also being tested as a monotherapy and in combination with tremelimumab, an investigational anti-CTLA4 monoclonal antibody and potential new medicine, as a treatment for patients with NSCLC, small cell lung cancer (SCLC), bladder cancer, head and neck cancer, liver cancer, cervical cancer, biliary tract cancer and other solid tumors. About AstraZeneca Support Programs AstraZeneca strives to ensure that appropriate patients and their oncologists have access to IMFINZI and relevant support resources. These include educational resources, an Oncology Nurse Educator program and affordability and reimbursement programs, such as?Access 360?. Additionally, AstraZeneca has launched?Lighthouse, a program that provides support to patients during any immune-mediated adverse events they may encounter during treatment, through medically trained Lighthouse Advocates. The program aims to make patients? treatment experience as comfortable as possible. Find out more about Lighthouse at LighthouseProgram.com or call 1-855-LHOUSE1 (1-855-546-8731).
