AZD9291, a third-generation orally irreversible epidermal growth factor receptor (EGFR) inhibitor, is under development by British drug maker AstraZeneca for the treatment of patients with metastatic EGFR T790M mutation-positive non-small cell lung cancer (NSCLC).
Lung cancer is the major cause of cancer death in the world while non small cell lung cancer (NSCLC) accounts approx. 85% of all lung cancer diagnosis. Approximately 50% of non–small cell lung cancer (NSCLC) patients who develop resistance to inhibitors of the epidermal growth factor receptor (EGFR) have acquired a second mutation, T790M. There are currently no approved treatments for patients who develop a T790 mutation.

AZD9291 mesylate
Also known as: AZD 9291 mesylate; AZD-9291 mesylate; HY-15772A; 1421373-66-1
AZD-9291 is a potent and selective mutated forms EGFR inhibitor(Exon 19 deletion EGFR IC50=12.92 nM, L858R/T790M EGFR IC50= 11.44 nM, wild type EGFR IC50= 493.8 nM).
Osimertinib (previously known as mereletinib[2] and AZD9291; trade name Tagrisso) is a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) drug[3][4] developed by AstraZeneca Pharmaceuticals - for mutated EGFR cancers.
Approvals and indications
In November 2015, after a Priority Review, the US FDA granted accelerated approval to osimertinib for the treatment of metastaticepidermal growth factor receptor (EGFR) T790M mutation-positive non-small cell lung cancer (NSCLC), as detected by an FDA-approved test, which has progressed on or after EGFR tyrosine kinase inhibitor (TKI) therapy.[5][6]
The FDA approval made reference to two clinical trials, in which an EGFR T790M mutation was confirmed by a Cobas EGFR mutation test; osimertinib was given as 80 mg once daily.[1][7]
AZD-9291 is a third-generation EGFR inhibitor, showed promise in preclinical studies and provides hope for patients with advanced lung cancers that have become resistant to existing EGFR inhibitors. AZD9291 is highly active in preclinical models and is well tolerated in animal models. It inhibits both activating and resistant EGFR mutations while sparing the normal form of EGFR that is present in normal skin and gut cells, thereby reducing the side effects encountered with currently available medicines

UPDATE
13 November 2015
One of fastest development programmes – from start of clinical trials to approval in just over two and a half years to meet unmet patient need
With objective response rate of 59% and duration of response of 12.4 months, TAGRISSO provides important new option for patients
AstraZeneca today announced that the US Food and Drug Administration (FDA) has approved TAGRISSO™ (AZD9291) 80mg once-daily tablets for the treatment of patients with metastatic epidermal growth factor receptor (EGFR) T790M mutation-positive non-small cell lung cancer (NSCLC), as detected by an FDA-approved test, who have progressed on or after EGFR tyrosine kinase inhibitor (TKI) therapy.
AZD9291 is the only approved medicine indicated for patients with metastatic EGFR T790M mutation-positive non-small cell lung cancer. This indication is approved under the FDA’s accelerated approval process based on tumour response rate and duration of response (DoR).
AZD9291 is an EGFR-TKI, a targeted cancer therapy, designed to inhibit both the activating, sensitising mutations (EGFRm), and T790M, a genetic mutation responsible for EGFR-TKI treatment resistance. Nearly two-thirds of NSCLC patients who are EGFR mutation-positive and experience disease progression after being treated with an EGFR-TKI develop the T790M resistance mutation, for which there have been limited treatment options.
Pasi A Jänne MD, PhD, Director, Lowe Center for Thoracic Oncology at Dana-Farber Cancer Institute, Scientific Director, Belfer Center for Applied Cancer Science and Professor of Medicine, Harvard Medical School, said: “In the AURA clinical studies, AZD9291 has demonstrated compelling early efficacy and tolerability in patients with EGFRm T790M metastatic non-small cell lung cancer. This treatment has the potential to become the standard of care for patients living with EGFRm T790M non-small cell lung cancer. The accelerated approval of AZD9291 highlights its clinical promise for a targeted group of patients and gives healthcare providers an important new option.”
Pascal Soriot, Chief Executive Officer, AstraZeneca, said: “The FDA approval of TAGRISSO marks an important milestone for lung cancer patients who urgently need new treatment options. We have built on our heritage in this area and acted on the breakthrough clinical evidence to ensure this next-generation medicine reaches patients in record time. As we advance our comprehensive lung cancer portfolio, we have the opportunity to treat greater numbers of patients across all stages of this disease through precision medicines, immunotherapies and novel combinations.”
AstraZeneca has collaborated with Roche to develop the cobas® EGFR Mutation Test v2 as the companion diagnostic for AZD9291. The cobas® EGFR Mutation Test v2 is intended to identify a range of EGFR mutations in patients with non-small cell lung cancer, including T790M.
AZD9291 was granted Fast Track, Breakthrough Therapy, Priority Review and Accelerated Approval status by the FDA. In Europe and Japan, AZD9291 was granted Accelerated Assessment and Priority Review status respectively. Interactions with regulatory authorities in the rest of the world are ongoing.
The FDA approval of AZD9291 is based on data from the two AURA Phase II studies (AURA extension and AURA2) which demonstrated efficacy in 411 EGFRm T790M NSCLC patients that had progressed on or after an EGFR TKI. In those trials, overall objective response rate ((ORR) a measurement of tumor shrinkage) was 59% (95% CI: 54% to 64%). In a supportive Phase I study in 63 patients, ORR was 51% and median duration of response was 12.4 months.
The AZD9291 tolerability profile showed that no individual severe grade 3+ adverse events occurred at ≥ 3.5%.The most common adverse events were generally mild to moderate and included diarrhoea (42% all grades; 1.0% Grade 3/4), rash (41% all grades; 0.5% Grade 3/4), dry skin (31% all grades; 0% Grade 3/4), and nail toxicity (25% all grades; 0% Grade 3/4). There are no contraindications for AZD9291. Warnings and precautions include interstitial lung disease, QT interval prolongation, cardiomyopathy and embryofoetal toxicity.
AZD9291 Development Programme
AZD9291 is being studied in the confirmatory trial, AURA3, an open label, randomised Phase III study designed to assess the efficacy and safety of AZD9291 versus platinum-based doublet chemotherapy in patients with EGFR T790M positive, locally advanced, or metastatic NSCLC who have progressed following prior therapy with an EGFR-TKI. AZD9291 is also being investigated in the adjuvant setting and in the metastatic first-line setting, including in patients with brain metastases, as well as in combination with other compounds.
NOTES TO EDITORS
About Non-Small Cell Lung Cancer
Lung cancer is the leading cause of cancer death among both men and women, accounting for about one-third of all cancer deaths, more than breast, prostate and colorectal cancers combined. Lung cancer has a five-year survival rate that is less than 20%. Approximately 85% of all lung cancers in the US are NSCLC; 10% to 15% of these are EGFR mutation-positive. Approximately two-thirds of patients treated with EGFR TKI therapy will acquire resistance related to the T790M mutation.
About AZD9291
AZD9291 80mg once-daily tablet is the first medicine indicated for the treatment of patients with metastatic epidermal growth factor receptor (EGFR) T790M mutation-positive non-small-cell lung cancer (NSCLC), as detected by an FDA-approved test, who have progressed on or after EGFR tyrosine kinase inhibitor (TKI) therapy. Non-clinical in vitro studies have demonstrated that AZD9291 has high potency and inhibitory activity against mutant EGFR phosphorylation across the range of clinically relevant EGFRm and T790M mutant NSCLC cell lines with significantly less activity against EGFR in wild-type cell lines.
Osimertinib has recently been published by the World Health Organisation (WHO) as the proposed International Non-proprietary Name (INN) for AZD9291, and may become formally adopted during November 2015. In the US, the American Medical Association accepted osimertinib as the United States Adopted Name (USAN).

ReplyDeleteI'm 55-year-old from Korean, I was diagnosed with second-stage liver cancer following a scheduled examination to monitor liver cirrhosis. I had lost a lot of weight. A CT scan revealed three tumors; one in the center of my liver in damaged tissue and two in healthy portions of my liver. No chemotherapy or radiotherapy treatment was prescribed due to my age, the number of liver tumors. One month following my diagnosis I began taking 12 (350 point) Salvestrol supplements per day, commensurate with my body weight. This comprised six Salvestrol Shield (350 point) capsules and six Salvestrol Gold (350 point) capsules, spread through the day by taking two of each capsule after each main meal. This level of Salvestrol supplementation (4,000 points per day) was maintained for four months.
