"These data further extend our understanding of MVP-S therapeutic mechanism of action and strongly implicate B cells in the clinical benefit from MVP-S based therapy," said Jeremy Graff, Ph.D., Chief Scientific Officer at IMV Inc.

Oliver Dorigo, M.D., Ph.D., Director and Associate Professor, Division Gynecologic Oncology, Department of Obstetrics and Gynecology at the Stanford University, CA, commented: "Immunotherapies that provoke both a T and B cell response have the potential to provide patients with a new first line therapy for hard-to-treat cancers such as advanced, recurrent ovarian cancer. We are encouraged by the B cell infiltration demonstrated using MVP-S supporting its ability to create a strong immune response in patients who have failed on prior lines of treatment."

Twenty-two women with advanced, recurrent ovarian cancer were enrolled in the DeCidE1 study. In August of this year, IMV announced the completion of the study and shared final top results: Objective Response rates (ORR) of 26.3%, Median Overall Survival of 19.9 months, and a 45% overall survival rate at nearly 2 years. The abstract released today by the ESMO (Free ESMO Whitepaper)-IO congress highlights that:

Enriched B cell infiltration was detected in on-treatment tumor samples, especially in patients who showed tumor reduction; the strongest increase was observed within memory B cells,
The frequency of systemic plasmablasts increased on-study in most of assessed patients and was more pronounced in patients with tumor shrinkage,
Antibodies to all 5 survivin peptides were detected in plasma samples and were more prominent in patients with tumor shrinkage.
These translational data provide new insights into the therapeutic mechanism of action of MVP-S, indicating an important role for B cells in mediating MVP-S induced anti-cancer immunity. The next IMV-sponsored clinical trial in patients with advanced, recurrent ovarian cancer is expected to be initiated in 2022.

The poster will be presented by Oliver Dorigo, M.D., Ph.D., Director and Associate Professor, Division Gynecologic Oncology, Department of Obstetrics and Gynecology at the Stanford University, CA.

Genetic evidence has already been shown to double success rates in clinical studies of new treatments, and the digitisation of human biology has the potential to improve drug discovery by more closely linking genes to patients. The new Institute aims to build on this scientific progress and improve how diseases are understood by drawing on recent advances in pathology, including how to measure changes on a cellular, protein, or tissue level.

Backed by £30 million from GSK, the Institute is intended to pioneer further improvements in how new medicines are discovered and developed. For example, scientists from GSK and Oxford will help prioritise those early R&D programmes most likely to succeed and match them to patients most likely to respond.

The Institute will evaluate and integrate new approaches in genetics, proteomics and digital pathology to understand detailed patterns of disease which vary amongst individuals. The initial focus of research will be on neurological diseases, such as Alzheimer’s and Parkinson’s Disease.

Prime Minister Boris Johnson said: "We saw first-hand during the pandemic how the ingenuity and pioneering spirit of UK scientists and the R&D sector saved thousands of lives, with the rapid development and delivery of medicines and vaccines around the world.

"I am delighted to see that GSK and the University of Oxford are today taking further steps to deepen our understanding of some of the most complex diseases, such as Parkinson’s. Together they will harness the power of scientific collaboration to progress cutting-edge technologies and accelerate drug discovery – helping to cement the UK’s role as a life sciences superpower."

Emma Walmsley, Chief Executive Officer, GSK said: "We are delighted to be joining with the University of Oxford in this new collaboration. By combining the strengths of our two scientific organisations and harnessing advanced technologies, the Oxford-GSK Institute exemplifies the UK’s track-record and continued ambition in life sciences. Together, our aim is to improve drug discovery and development to help bring new and better medicines for patients."

Professor Louise Richardson, Vice-Chancellor of the University of Oxford, said: "On behalf of colleagues across Oxford I would like to say how delighted we are by this new initiative with GSK. The Institute will create a unique partnership with staff from the university’s medical school and GSK working side-by-side to research and develop treatments for some of the most difficult to treat diseases. In addition, the Institute, in keeping with our educational mission, will provide training and build capacity in Britain’s academic and bioscience sectors."

The genetic and genomic revolution of the past decade has amassed vast datasets of promising targets for medicine discovery. These datasets can be combined with functional genomics to provide deep understanding of disease at a molecular level.

By harnessing this understanding, as well as the power of machine learning, the Institute will uncover new indicators and predictors of disease and use them to accelerate the most promising areas for drug discovery. This is particularly important for GSK as it prioritises the large number of genetically informed drug targets generated from its collaborations with organisations, such as 23andMe and UK Biobank. The Institute will also aim to provide new measurements to establish proof of concept for potential medicines earlier in the R&D process, by better identifying the most appropriate patients to enrol in clinical trials, thus accelerating drug development timelines.

GSK and Oxford bring complementary capabilities and expertise into the Institute. GSK has leading capabilities in human genetics and functional genomics, and an in-house artificial intelligence and machine learning function, including its AI hub in central London. The University of Oxford has similar expertise but together they will be using patient, molecular information and state-of-the-art platforms to pinpoint the GSK targets that are most likely to succeed and be developed into safe, effective, disease mechanism-based medicines.

Diseases driven by neuro-immunological mechanisms including Alzheimer’s, Parkinson’s, Multiple Sclerosis (MS), Frontal Temporal Dementia, Amyotrophic Lateral Sclerosis (ALS) and Pain will be within the initial scope of the Institute. GSK has a rich pipeline of genetically informed targets and clinical projects in these areas.

The Institute will recruit a number of new research groups, in addition to drawing upon existing expertise from both GSK and Oxford. Five GSK/Oxford fellowships will be provided for early to mid-career researchers to establish themselves as Principal Investigators researching areas aligned with the Institute’s aims and objectives.

The Institute will have its base in the Nuffield Department of Medicine, and be closely associated with colleagues from across departments, including the University’s Wellcome Centre for Human Genetics and Big Data Institute. GSK and Oxford are in active discussions regarding the nature of the first projects which are anticipated to start in the second half of 2022 and will use the latest laboratory and data science platforms and approaches. A completely new way of collaborating will be established where research teams will have both GSK and University members, including secondments between both institutions.

The Directors of the Institute will be Professor John Todd, Director of the Wellcome Centre for Human Genetics and Dr Tony Wood, SVP, Medicinal Science and Technology at GSK.

On December 2, 2021 Onconova Therapeutics, Inc. (NASDAQ: ONTX), a clinical-stage biopharmaceutical company focused on discovering and developing novel products for patients with cancer, reported that early preliminary data from an investigator-initiated Phase 2 open label trial of rigosertib monotherapy in advanced squamous cell carcinoma complicating recessive dystrophic epidermolysis bullosa (RDEB-associated SCC) were presented at the Austrian Society of Dermatology and Venerology Annual Conference 2021, which took place from November 25 – 27, 2021 (Press release, Onconova, DEC 2, 2021, View Source [SID1234596407]).

RDEB is an ultra-rare condition caused by a lack of type VII collagen protein expression. Type VII collagen protein is responsible for anchoring the skin’s inner layer to its outer layer, and its absence leads to extreme skin fragility and chronic wound formation in RDEB patients. Over time, many of these patients develop squamous cell carcinomas (SCCs) that typically arise in areas of chronic skin wounding and inflammation. Preclinical investigations demonstrated overexpression of polo like kinase 1 (PLK1) in RDEB-associated SCC tumor cells. These tumors show a highly aggressive, early metastasizing course, making them the primary cause of death for these patients, with a cumulative risk of death of 70% and 78.7% by age 45 and 55, respectively1,2. These neoplasms show limited response rates of mostly short duration to conventional chemo- and radiotherapy as well as targeted therapy with epidermal growth factor and tyrosine kinase inhibitors1,3.

Data from the recent presentation are from a 24-year-old RDEB patient with a history of multiple, unresectable SCCs that were unresponsive to prior treatments including cemiplimab. Results showed that intravenously administered rigosertib had an acceptable safety profile and that the patient experienced sustained clinical and histological remission of all target lesions without signs of metastatic disease following 13 treatment cycles. The patient remains on study and the trial remains ongoing. The enrollment of additional patients is anticipated at sites in Salzburg, Austria; London, UK; and Philadelphia, Pennsylvania.

"Though the trial’s currently available data are from only a single patient, they represent an exciting and powerful finding that warrants further study," said Andrew South Ph.D., Associate Professor, Department of Dermatology & Cutaneous Biology, Thomas Jefferson University. "RDEB-associated SCC is an indication with an extremely high unmet medical need, as it is invariably fatal with treatment options that have so far yielded disappointing results. The data generated in preclinical models suggesting rigosertib’s robust activity against PLK1 have now been confirmed in the clinic and suggest that rigosertib may play a role in other more common cancers driven by PLK1."

The physicians caring for the patient, Dr. Bauer, Principal Investigator, and Dr. Laimer, Sponsor Medical Expert of the trial, added in a joint statement, "To see a complete response in a patient that has failed multiple prior therapies is highly encouraging and, together with preclinical data, suggests that rigosertib’s ability to inhibit PLK1 may position it as a novel treatment option that can significantly improve upon the current standard-of-care. We look forward to the further evaluation of this hypothesis through the continued advancement of the trial."

A copy of the poster, titled "Rigosertib for locally advanced/metastatic EB-associated SCC," is available on the "Scientific Presentations" section of the Onconova website.

Dr. Xuebin Liao, a professor of Pharmaceutical Science at Tsinghua University and a member of the board of directors at MingMed Biotechnology, said, "HPK1 plays a key role in controlling immune responses against various cancers. Targeting HPK1 effectively regulates several important immune cells, activating their synergistic anti-tumor effects."

"MingMed’s scientists have built a solid foundation around the molecular mechanism underlying how HPK1 functions in promoting the exhaustion of local anti-tumor immunity," Liao introduces. "Additionally, our HPK1 inhibitor PRJ1-3024 has showed very good selectivity as a drug candidate and FDA approval is a crucial milestone announcing MingMed as a potential key player in the competition to find novel cancer immunotherapeutics. We will continue to push our clinical studies for the benefits of cancer patients around the world."

Meanwhile, MingMed also announced completion of Phase I clinical trials for their dry age-related macular degeneration (dry AMD) drug QA102 in the US.

Mr. Yan Zhang, CEO of MingMed Biotechnology, commented, "QA102 is a new drug to treat dry AMD, a blinding eye disease with currently no cure that attracts enormous clinical demand with broad market prospects. Successful completion of Phase 1 clinical trials for QA102 in the US represents the first endeavor from a Chinese R&D team to develop a first-in-class ophthalmic drug," Zhang continues. "The progress achieved by our scientists in the development of PRJ1-3024 and QA102 demonstrates that MingMed Biotechnology has built a solid foundation to make breakthrough scientific innovations, and is also capable of designing and managing the development of multiple product pipelines in an effective and efficient manner. It is our hope to develop more innovative medicines for human health."

This funding will also be used to advance three novel programs through phase 1: BOXR1030 is the company’s lead CAR-T program for the treatment of various solid tumors expressing GPC3. It’s based on the proprietary BOXR platform that aims to enhance the fitness of T cells in the hostile tumor microenvironment. The study is scheduled to start early 2022. SOT102 is a novel ADC with a best-in-class potential for Claudin 18.2 targeting therapies. A phase 1 dose escalation in patients with gastric and pancreatic cancer shall start in March 2022. Finally, SOTIO plans to initiate a phase 1 study with our first IL-15 based immunocytokine using a PD-1 inhibitor as the targeting arm by the end of 2022.

"We are very excited and grateful for the continued strong support we’ve received from PPF Group today and since our inception," said Radek Spisek, Ph.D., CEO of SOTIO. "This very significant funding will allow us to advance a broad pipeline of unique clinical stage programs to key value inflection points."

"Over the last several years SOTIO has created an attractive pipeline of programs based on multiple differentiated modalities," said Ladislav Bartonicek, CEO and shareholder of PPF Group. "We appreciate the successful track record of execution by the Company to this point and are confident that this funding will further enable SOTIO to continue building a unique, privately financed oncology company with a mature and diversified pipeline. It will be an important step to achieve our long-term goal of building a fully integrated oncology business."

The funding is contingent on the achievement of certain development and regulatory milestones.
