AstraZeneca will present new data from its pipeline of investigational cancer medicines over the next three days at the European Society of Medical Oncology (ESMO) 2014 Congress in Madrid. Together with MedImmune, its global biologics research and development arm, the company will present data from over 40 abstracts, building on results highlighted earlier this year at the American Society for Clinical Oncology (ASCO) congress.
- Preliminary results in the ongoing Phase I MEDI4736 (PD-L1) + tremelimumab (CTLA-4) combination study in patients with non-small cell lung cancer (NSCLC) who have already received prior cancer treatments.
- Updated data from a Phase I monotherapy study of MEDI4736 in patients with metastatic squamous cell carcinoma of the head and neck (SCCHN).
- Further data from the Phase I/II study of AZD9291 in patients with epidermal growth factor receptor mutation positive (EGFRm) T790M+ advanced NSCLC who had disease progression following treatment with an EGFR tyrosine kinase inhibitor (TKI).
Briggs Morrison, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca said: “At ASCO we presented data demonstrating the strength and rapid progression of our oncology pipeline, which we believe has the potential to redefine the way cancer patients are treated. The data being presented here at the ESMO 2014 Congress further builds our clinical understanding of the key assets across our core areas of focus: immuno-oncology, the genetic drivers of cancer and acquired resistance and DNA damage repair. We are encouraged by the results we are seeing and look forward to providing further updates as we continue to work at pace to get these potentially life-changing medicines to patients.”
MedImmune will present updates on its novel immunotherapy portfolio at the ESMO 2014 Congress through eight abstracts, which reinforce the clinical activity and tolerability of MEDI4736 as monotherapy and highlight the potential of the combination of MEDI4736 and tremelimumab.
Specifically, preliminary data was presented today from the ongoing Phase I study of MEDI4736 in combination with tremelimumab in NSCLC patients who have already received prior cancer treatments (Antonia, abstract #1327P). The data covered anti-tumour activity and the tolerability profile of the combination.
“We are pleased with the results from MEDI4736 in combination with tremelimumab,” said Edward Bradley, Senior Vice President, R&D and Oncology iMED Head, MedImmune. “While it is still early with a limited data set, the tolerability profile is encouraging. We have also seen some evidence of clinical activity in patients who have failed prior lines of therapy and whose tumour does not express PD-L1. This supports our strategy to explore this combination more broadly, particularly in the PD-L1 negative population. This trial will identify the optimal dose to take into our Phase III clinical programme.”
MEDI4736 is an investigational, engineered, human monoclonal antibody directed against an immune system ‘checkpoint’, known as programmed cell death ligand 1 (PD-L1). Tremelimumab targets a separate immune checkpoint, CTLA-4. Several checkpoints such as PD-L1 and CTLA-4, which the body normally uses to dampen the immune response, can be hijacked by tumour cells to escape detection by the immune system and facilitate malignant growth. Immunotherapies are designed to enable the immune system to counteract these tactics employed by cancer cells. By targeting more than one hijacked checkpoint, combination therapies have the potential to be more effective than monotherapy in treating this disease.
MedImmune has initiated additional Phase I immunotherapy combination trials, including MEDI4736 + MEDI0680 (PD-1) and MEDI4736 + MEDI6469 (OX40)*.
Ongoing Phase I data were also presented today, assessing the clinical activity and safety profile of MEDI4736 as a monotherapy in patients with NSCLC (Antonia, abstract #1325P). On Sunday, 28 September, MedImmune will present additional MEDI4736 monotherapy data in a Phase I dose-expansion study of patients with solid tumours. This data set will provide further information on the clinical activity and tolerability profile of MEDI4736 across a range of solid tumours, including pancreatic cancer, gastric cancer and hepatocellular cancer (Segal, abstract #1058PD). A separate analysis of patients with metastatic SCCHN will also be shared (Fury, abstract #988PD). The Phase I data, coupled with the pre-clinical data, support the accelerated development of MEDI4736 into Phase III clinical trials in both NSCLC and SCCHN.
Separately, MedImmune has also recently commenced a Phase I human OX40 agonist (MEDI6383) monotherapy study in cancer patients with recurrent or metastatic solid tumors.
On Sunday, 28 September, AstraZeneca will present updates on key assets in its small molecule portfolio, including the investigational NSCLC medicine AZD9291, a highly selective, irreversible inhibitor of both the activating sensitising EGFR mutation (EGFRm) and the resistance mutation T790M, IRESSA® (gefitinib) and the PARP inhibitor olaparib.
Updated data from the ongoing AURA Phase I/II study (Yang, Abstract #449PD) will provide an update on the activity and safety of AZD9291 in patients with EGFRm T790M+ advanced NSCLC whose disease had progressed following treatment with an EGFR TKI. This builds on data from the AURA study presented earlier in the year at ASCO. AstraZeneca has initiated both Phase II and Phase III studies in this patient population (AURA 2 and AURA 3 respectively).
In addition, a Phase III study evaluating AZD9291 in first line EGFRm advanced NSCLC is scheduled to start later this year.
AstraZeneca is also currently investigating combinations of AZD9291 with MEDI4736, and with other investigational drugs selumetinib (small molecule MEK inhibitor) and AZD6094 (small molecule MET inhibitor) in NSCLC.
Antoine Yver, Head of Oncology, Global Medicines Development, AstraZeneca, said “The updated data we are presenting at the ESMO 2014 Congress reinforce our strategy of moving rapidly into Phase III development with AZD9291 in EGFRm T790M+ advanced non-small cell lung cancer. We have already made significant progress with our accelerated development programme and we anticipate filing for regulatory approval in the US in the second half of 2015.”
AstraZeneca will also present data from the Phase III IMPRESS study for IRESSA, a second line, combination study in patients with EGFRm advanced NSCLC who have acquired resistance to first line IRESSA.
Separately, new data will be presented on the impact of olaparib on the quality of life of patients with BRCA mutated platinum-sensitive relapsed ovarian cancer. The Committee for Medicinal Products for Human Use is expected to provide its opinion on olaparib in the EU on 23 October 2014, and the US FDA Prescription Drug User Fee Act date is set for 3 January 2015.
AstraZeneca will host a briefing for analysts and investors at the ESMO 2014 Congress on the evening of Sunday, 28 September 2014 from 18:30 – 20:00 CEST. Details are available at: astrazeneca.com/investors.
