Fourteen AstraZeneca medicines and potential new medicines from the pipeline will be featured across 33 abstracts showcasing the Company’s leadership across different types and stages of breast cancer, including three oral presentations.

Breast cancer is now the most diagnosed cancer worldwide with an estimated 2.3 million people diagnosed in 2020.1

Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: "Continuing our year of breakthroughs in breast cancer, our data at SABCS will reinforce the practice-changing potential of Enhertu with new analyses from the DESTINY-Breast03 trial. Early data from the BEGONIA and TROPION-PanTumor01 trials demonstrate great promise in treating patients who have limited treatment options. These data build on our decades of experience in pioneering medicines to redefine care for patients."

Dave Fredrickson, Executive Vice President, Oncology Business Unit, AstraZeneca, said: "Progress in breast cancer increasingly involves more personalised approaches to treating patients across subtypes and stages of disease, which is a key focus of our data at this year’s SABCS. Our extensive knowledge of breast cancer disease biology and the patient experience fuel our ambition to deliver medicines that can truly revolutionise and reshape treatment for every type of breast cancer patient."

Transforming the treatment of advanced breast cancers with antibody drug conjugates (ADCs)
An oral presentation will share further results from a range of patient subgroups from the DESTINY-Breast03 Phase III trial, including those with stable brain metastases and patients characterised by hormone receptor status, number of prior lines of therapy or status of visceral metastasis.

Results from DESTINY-Breast03 demonstrated superior progression-free survival (PFS) for Enhertu (trastuzumab deruxtecan) versus trastuzumab emtansine (T-DM1) in patients with HER2-positive breast cancer previously treated with trastuzumab and a taxane.

In another oral presentation, updated results from the TROPION-PanTumor01 Phase I trial will continue to build promising evidence of the anti-tumour activity of datopotamab deruxtecan in patients with triple-negative breast cancer (TNBC).

Treating breast cancer early where there is more opportunity for cure
New data on patient quality of life from the OlympiA Phase III trial of Lynparza (olaparib) will be presented as an oral presentation.

These patient-reported outcomes data will provide compelling evidence that further supports Lynparza as a potential treatment option for the adjuvant treatment of patients with germline BRCA-mutated (gBRCAm) high-risk HER2-negative early breast cancer.

The supplemental New Drug Application of Lynparza for this indication was recently granted Priority Review by the US Food and Drug Administration.

Changing the treatment landscape with next-generation medicines and novel combinations
A poster and spotlight poster discussion will share results from the BEGONIA Phase Ib/II trial testing Imfinzi (durvalumab) combinations in advanced/metastatic TNBC with data from arm 1 (Imfinzi plus paclitaxel), arm 2 (Imfinzi, paclitaxel and capivasertib) and arm 5 (Imfinzi, paclitaxel and oleclumab), which will further demonstrate the benefits of combining immune checkpoint inhibitors with other novel molecules.

Additionally, ongoing trials posters will share information about the ongoing SERENA-4 Phase III trial which evaluates our next-generation oral selective oestrogen receptor degrader (SERD) camizestrant (AZD9833) in combination with CDK4/6 inhibitors in the 1st-line treatment of patients with oestrogen receptor (ER)-positive, HER2-negative advanced breast cancer, and the SERENA-6 Phase III trial of camizestrant with CDK4/6 inhibitors in patients with hormone receptor (HR)-positive, HER2-negative metastatic breast cancer with an ESR1 mutation.

A further ongoing trial poster will share information on the CAPItello-292 Phase III trial, evaluating the benefit of adding capivasertib (an AKT inhibitor) to the treatment regimen of Faslodex (fulvestrant) and palbociclib in patients with HR-positive, HER2-negative locally advanced, unresectable or metastatic breast cancer.

Enhertu and datopotamab deruxtecan are developed and commercialised in collaboration with Daiichi Sankyo worldwide, except in Japan where Daiichi Sankyo maintains exclusive rights. Lynparza is developed and commercialised in collaboration with MSD (Merck & Co., Inc. in the US and Canada).

Notes

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.

AstraZeneca aims to continue to transform outcomes for HR-positive breast cancer with foundational medicines Faslodex and Zoladex and the next-generation oral SERD and potential new medicine camizestrant.

PARP inhibitor Lynparza is a targeted treatment option for metastatic breast cancer patients with an inherited BRCA mutation. AstraZeneca with MSD continue to research Lynparza in metastatic breast cancer patients with an inherited BRCA mutation and are exploring new opportunities to treat these patients earlier in their disease.

Building on the first approval of Enhertu, a HER2-directed ADC, in previously treated HER2-positive metastatic breast cancer, AstraZeneca and Daiichi Sankyo are exploring its potential in earlier lines of treatment and in new breast cancer settings.

To bring much needed treatment options to patients with triple-negative breast cancer, an aggressive form of breast cancer, AstraZeneca is testing immunotherapy Imfinzi in combination with other oncology medicines, including Lynparza and Enhertu, evaluating the potential of AKT kinase inhibitor, capivasertib, in combination with chemotherapy, and collaborating with Daiichi Sankyo to explore the potential of TROP2-directed ADC, datopotamab deruxtecan.

AstraZeneca in oncology
AstraZeneca is leading a revolution in oncology with the ambition to provide cures for cancer in every form, following the science to understand cancer and all its complexities to discover, develop and deliver life-changing medicines to patients.

The Company’s focus is on some of the most challenging cancers. It is through persistent innovation that AstraZeneca has built one of the most diverse portfolios and pipelines in the industry, with the potential to catalyse changes in the practice of medicine and transform the patient experience.

AstraZeneca has the vision to redefine cancer care and, one day, eliminate cancer as a cause of death.

On December 2, 2021 Integra Therapeutics, a biotechnology company that is creating next-generation gene writing tools to boost the efficiency and safety of advanced therapies, reported the company has completed its first round of funding for €4.5 million with Advent France Biotechnology (France), Invivo Capital (Spain) and Takeda Ventures (USA) (Press release, Integra Therapeutics, DEC 2, 2021, View Source [SID1234654526]).

Integra Tx was founded in late 2020 as a spin-off of Pompeu Fabra University (UPF) based on technology developed in the Translational Synthetic Biology Lab led by Dr Marc Güell (EMBO Young Investigator, National Research Award for Young Talent and co-founder of two biotech firms).

The great potential of this novel gene writing technology lies in the fact that it resolves some of the main technical limitations of gene therapy: it can be used to paste DNA sequences of any size gene with high precision. Advanced therapies are one of the pillars of the medicine of the future and are aimed at both preventing and treating genetic and oncological diseases that, for now, are incurable.

The funds raised in this round will allow Integra Tx to complete the prototype of the new gene writing technology platform, carry out preclinical validation using in vivo and ex vivo models, and manage its patent portfolio in 2022 and 2023. After that, the company plans to open a Series A round to seek regulatory approval and carry out clinical trials with patients.

"We’re very proud to be transferring our scientific knowledge and technological skills in gene editing from the lab to society. We thank all our investors for their commitment to Integra Tx and to making advanced therapies safer and more effective, and getting them to patients that urgently need them," says Dr Avencia Sánchez-Mejías, co-founder and CEO of Integra Tx. Sánchez-Mejías joined the UPF Translational Synthetic Biology Lab in 2018 after doing research at the Institute of Biomedicine of Seville, the National University of Singapore and the University of Miami Miller School of Medicine.

Dr Marc Güell, co-founder and CSO of Integra Tx, explains, "the Integra Tx technology platform is very promising because it is an evolution of the CRISPR-Cas techniques. We’ve found a way to merge them with transposase and integrase proteins that have a great capacity for gene transfer and to not depend on viral vectors for transporting the components into the cell, which is a step forward in making these therapies safer." Plus, it has applications both in vivo (directly in patients) and ex vivo (outside of patients).

Matthieu Coutet, Managing Partner at Advent France Biotechnology, adds: "We decided to invest in Integra Tx because we believe in its seasoned scientific and management team. Its founders have shown a strong passion and ambition to move Integra Tx’s technology forward, combined with a proven expertise in gene editing and advanced therapies."

Dr Luis Pareras, Managing Partner at Invivo Capital, says: "We’re thrilled with the possibilities Integra Tx’s plataform can develop to solve the problem of cargo size in gene therapy. We’re also very pleased with the international syndicate supporting this seed round, in yet another example of technology transfer opportunity and the competitiveness of the biotech ecosystem in Spain."

Miles Gerson, Takeda Ventures Partner and Senior Investment Director, says: "Takeda Ventures is very excited to support Integra Tx and their next generation gene writing platform with many potential applications to benefit patients."

On December 2nd, 2021 BioRay Pharmaceutical Co., Ltd.

Zuberitamab (HS006) is a human-mouse chimeric monoclonal antibody that specifically binds to B-lymphocyte antigen CD20 and can kill B cells via ADCC and CDC action. Zuberitamab (HS006) has demonstrated a favorable safety and efficacy profile in B-cell lymphoma in clinical trials. As B cells play an important role in the pathogenesis of autoimmune diseases such as primary immunologic thrombocytopenic purpura (ITP), rheumatoid arthritis (RA), and multiple sclerosis (MS), Zuberitamab (HS006) has the potential to be used in the treatment of autoimmune diseases.

Primary immunologic thrombocytopenic purpura (ITP) is an acquired autoimmune disease characterized by thrombocytopenia. The pathogenesis of ITP is mainly due to the loss of immune tolerance to the patient’s platelet membrane antigens. The patient’s B cells produce antibodies against different platelet antigens, leading to the formation of antigen-antibody complexes, and resulting in excessive destruction of platelets in the spleen or liver. Meanwhile, thrombopoiesis is impaired. Zuberitamab (HS006) specifically clears B-lymphocytes, thereby reducing autoantibody production and platelet destruction. Zuberitamab (HS006) is expected to bring an alternative treatment optionfor ITP patients and improve their quality of life.

"Zuberitamab (HS006) is a self-developed monoclonal antibody that targets the CD20 protein on the surface of B cells. It can rapidly, thoroughly and durably remove CD20+ B cells, and this effect is reversible after drug withdrawal, " said by Dr. Haibin Wang, the Chief Medical Officer (CEO) of BioRay, "The Phase III Clinical trial of Zuberitamab (HS006) for primary treatment of diffuse large B-cell lymphoma has completed the observation of the primary endpoint, and the study results confirmed its good safety, tolerability and efficacy, which provides strong support for the subsequent clinical development of ITP. Based on the existing achievements, BioRay will make every effort to promote its clinical research in ITP and other diseases and promote the early launch of this product in China to benefit more patients."

On December 2, 2021 Tune Therapeutics, a biotechnology company pioneering the creation of epi-therapeutic medicines, reported it launched with its powerful and precise genetic tuning platform, TEMPO (Press release, Tune Therapeutics, DEC 2, 2021, View Source [SID1234630692]). This cutting-edge technology dials gene expression up or down to desired levels – with the potential to reverse pathways of cancer, genetic disease, and aging by changing cell fate and function at will.

"Genetic medicine is at a tipping point," said Matt Kane, CEO of Tune Therapeutics. "We now understand that the driving force of human health and disease is not our genes, but the epigenomic elements that shape and control them. Until now, scientists and bioengineers lacked the combined understanding, clinical expertise, and technology needed to make epigenomic therapies a practical reality. Now, we have all three."

TEMPO Platform

Tune’s proprietary TEMPO platform can rapidly target and adjust the epigenomic machinery of the cell, which shapes DNA and controls gene expression. By varying specific control modules in an iterative process, TEMPO can fine-tune expression toward healthy levels – even in diseases involving multiplex or polygenic interactions.

Unlike genome editing, the tuning process does not generate double- or single-strand breaks in DNA and makes no permanent changes to the DNA sequence. This de-risks the precise targeting of entire gene networks, allowing Tune to simultaneously turn silenced genes on and dial over-expressed genes down, in a practical, therapeutic context.

Tune has already shown that TEMPO can locate epigenomic elements involved in several intractable genetic conditions – revealing targets and networks that would be invisible or inaccessible to gene editing approaches. Moreover, Tune can optimize TEMPO to command expression of individual genes or networks with remarkable specificity and precision. This opens the door to an entirely new class of epi-therapeutics.

"The exciting challenge in front of us is taking these transformative advances in technology and extending their potential for our greater society," said Charlie Gersbach, PhD, Acting Chief Scientific Officer, Tune Therapeutics. "From proof of concept in rare, single-gene disorders to common conditions that aren’t linked to a single gene mutation – but are treatable through epigenomic control and constitute the vast majority of human diseases."

Veteran Genomic Medicine Leadership Team

Tune is launching with a veteran leadership team, endowed with deep expertise in gene and cell therapy, genome editing, and epigenetics.

Matt Kane, Chief Executive Officer
Akira Matsuno, Co-Founder, President and Chief Financial Officer
Charlie Gersbach, Ph.D., Co-Founder, Acting Chief Scientific Officer
Fyodor Urnov, Ph.D., Co-Founder, Scientific Advisory Board
Heidi Zhang, Ph.D., Executive Vice President, Head of Technical Operations
Blythe Sather, Ph.D., Vice President, Head of Research
In addition, Tune’s Board of Directors includes Mr. Kane, Dr. Gersbach, Ali Behbahani, M.D., (New Enterprise Associates), and co-founder Dan McHugh (Emerson Collective).

Drawing upon deep, local talent pools in Durham and Seattle, Tune has assembled two highly seasoned discovery and development teams, secured foundational intellectual property from Duke University, and raised $40 million from top-tier investors – including co-leads New Enterprise Associates and Emerson Collective, with Hatteras Venture Partners, Mission BioCapital, and others joining the round. This financing will enable Tune to rapidly advance its preclinical research, attract top-tier talent, and further develop its therapeutic platform.

"Tune is effectively pioneering a brand-new therapeutic modality," said Dr. Behbahani. "With the unbound potential of this approach, and their collective successes in the field, Tune is primed to become a transformative presence in modern biomedicine."

On 2 December 2021 Oncology One Pty Ltd, reported a partnership with WEHI (Walter and Eliza Hall Institute of Medical Research) to develop new drugs for the treatment of cancer, in collaboration with Curtin University (Press release, Oncology One, DEC 2, 2021, View Source [SID1234629324]).

The collaboration centres on the development of novel small molecule drugs to treat solid tumours, initially focusing on breast cancer.

The project will seek to identify small molecule compounds that specifically inhibit a novel target in breast cancer that drives tumour growth. If successful, further work will need to be undertaken to refine these compounds towards candidate therapies, which could enter clinical trials in due course.

Chair of Oncology One’s Scientific Advisory Board, Dr Ian Street, said: "This project represents an important next step for Oncology One in building a pipeline of drug discovery programs that are highly differentiated and address unmet clinical needs. We have made great progress in early breast cancer detection, and this has had a dramatic effect on reducing mortality. However, if early disease is missed and the cancer metastasises, then unfortunately prognosis is poor. We are very much looking forward to a productive collaboration with David and Pieter, and the drug discovery and research teams at WEHI and Curtin".

This transcontinental project originated in the research labs of Professor David Komander at WEHI and Associate Professor Pieter Eichhorn at Curtin University. The objective is to develop a new therapeutic for treating metastatic ER+ breast cancers that have escaped current treatments. The new therapeutic also has the potential to address unmet clinical needs in other cancers such as colorectal and brain.

WEHI Ubiquitin Signalling Division Head, Professor David Komander, said: "The ubiquitin system offers many opportunities for innovative cancer treatments. We are delighted to work with Oncology One on this exciting project and to translate our research to benefit cancer patients. The project was initially born in a collaboration with Curtin University, and we are excited to draw upon our strengths and to work with industry to improve treatments for a disease that continues to impact so many lives."

Breast cancer is the most prevalent form of cancer in women and accounts for over 2 million cases and over 600,000 deaths per year worldwide according to the World Health Organisation (WHO). The emergence of resistance to existing therapies is a major challenge in the treatment of many people with breast cancer, and new treatment modalities are urgently required to improve patient outcomes.

Curtin University Associate, Professor Pieter Eichorn, said: "While breast cancer survival rates have improved, there are millions of patients who don’t respond to current treatments. Through this collaboration drawing on the expertise of WEHI in drug discovery and Oncology One in drug development, we can find the best way to bring our cancer treatment discoveries to patients, and make a real difference to them and to their loved ones and families."
