AstraZeneca and Daiichi Sankyo presented updated results from the DESTINY-Breast01 trial for ENHERTU (fam-trastuzumab deruxtecan-nxki), showing continued efficacy in HER2-positive metastatic breast cancer patients. With a median follow-up of 20.5 months, the trial indicated a 61.4% objective response rate (ORR) and a median duration of response of 20.8 months. The median progression-free survival was 19.4 months, and 74% of patients remained alive at 18 months. The treatment demonstrated consistent safety profiles, though 18.5% discontinued due to adverse events. ENHERTU is approved in the US and Japan.

A pooled analysis of 762 CLL patients treated with CALQUENCE (acalabrutinib) monotherapy showed a low incidence of cardiac adverse events (AEs) leading to treatment discontinuation. At a median follow-up of 25.9 months, 17% reported cardiac AEs, with only 0.9% discontinuing treatment due to these issues. The analysis concluded that CALQUENCE has a favorable cardiovascular safety profile, akin to untreated CLL patient populations. AstraZeneca plans further trials for CALQUENCE in CLL, aiming to enhance treatment efficacy and safety.

Long-term follow-up data from the ACE-LY-004 Phase II trial showed CALQUENCE® (acalabrutinib) effectively treats relapsed or refractory mantle cell lymphoma (MCL). Patients achieved a median progression-free survival of 22 months, with overall survival data still pending after three years. The trial included 124 patients, demonstrating a 28.6% overall response rate and 41.9% estimated duration of response at 36 months. The safety profile remained stable, with 11% discontinuing due to adverse events. CALQUENCE is an important treatment option, particularly as MCL is aggressive and typically diagnosed late.

AstraZeneca is set to present new findings on breast cancer therapies at the 2020 San Antonio Breast Cancer Symposium (SABCS) from December 8-11. Key highlights include updated data from the DESTINY-Breast01 Phase II trial, showcasing ENHERTU's efficacy in HER2-positive metastatic breast cancer, and promising results from the SERENA-1 Phase I trial evaluating AZD9833 in HR-positive, HER2-negative advanced breast cancer. AstraZeneca emphasizes its commitment to improving outcomes for breast cancer patients through innovative treatments and collaborations.

AstraZeneca's IMFINZI® (durvalumab) has received FDA approval for a new 1,500mg fixed dosing option every four weeks for patients with unresectable Stage III non-small cell lung cancer (NSCLC) post-chemoradiation and previously treated advanced bladder cancer. This alternative to the current weight-based dosing aims to improve patient convenience and reduce healthcare visits. This decision follows the FDA's Priority Review status and is based on data from pivotal clinical trials, including the PACIFIC and CASPIAN studies.

AstraZeneca will showcase new research at the 62nd ASH Annual Meeting from December 5-8, 2020, focusing on blood cancers. The Company is presenting 27 abstracts related to five medicines, including CALQUENCE. Highlights include a pooled analysis of CALQUENCE’s cardiovascular safety in CLL, promising follow-up data in MCL, and findings on roxadustat for various anemia conditions. The data aim to address unmet needs in hematology and demonstrate AstraZeneca's commitment to improving treatments for patients with hematologic malignancies.

A recent study highlights that 81.1% of patients with NYHA class II-IV heart failure with reduced ejection fraction (HFrEF) may qualify for treatment with FARXIGA (dapagliflozin). This data was presented at the AHA’s Scientific Sessions 2020, based on over 150,000 patient records from U.S. hospitals. FARXIGA is FDA-approved to lower cardiovascular death and hospitalization risks in adults with HFrEF. The study underscores the urgent need for clinical practice to adopt this treatment, ultimately aiming to fill gaps in care for heart failure patients.

AstraZeneca and Amgen announced positive results from the NAVIGATOR Phase III trial of tezepelumab for severe, uncontrolled asthma. The trial met its primary endpoint with a significant reduction in the annualized asthma exacerbation rate (AAER) over 52 weeks compared to placebo. Tezepelumab was well tolerated and showed efficacy in patients with low eosinophil counts. This promising data supports the FDA's Breakthrough Therapy Designation for patients without an eosinophilic phenotype. Severe asthma affects approximately 34 million people globally.
