SIRP-alpha is a receptor expressed by myeloid lineage cells such as Dendritic Cells (DCs), tumor-associated macrophages (TAMs) and Myeloid-Derived Suppressor Cells (MDSCs). In targeting SIRP- alpha, OSE-172 prevents the ligand CD47 from binding to and triggering the cellular inhibitory effects of SIRP-alpha. OSE-172 has the potential to enhance anti-tumor immunity by improving T cell activity through enhancement of DC antigen presentation functionality, potentiating the phagocytic and inflammatory properties of macrophages in the tumor microenvironment and enabling differentiation of MDSCs to an effector state.

"This partnership with Boehringer Ingelheim is a real recognition of the value of our innovative approach to treating cancer and will create an exciting new alliance to fuel the phase 1 development of OSE-172," said Dr. Dominique Costantini, CEO of OSE Immunotherapeutics. "Boehringer Ingelheim’s expertise and insights will be invaluable as we step up the clinical development and work to commercialize this new treatment paradigm."

"We are excited to partner with OSE Immunotherapeutics to develop this promising, novel cancer immunotherapy," said Jonathon Sedgwick, Ph.D., Global Head Cancer Immunology & Immune Modulation Research at Boehringer Ingelheim. "A key area of focus is the identification of drugs that target myeloid cell immune regulatory receptors of which SIRP-alpha is a leading example. We are dedicated to developing ground-breaking, first-in-class therapies that can transform the lives of patients and help win the fight against cancer."

Boehringer Ingelheim has acquired the global rights to develop, register and commercialize OSE-172, a monoclonal antibody targeting SIRP-alpha which is expressed in myeloid lineage cells, as part of their continued commitment to research and innovation in immuno-oncology. Under the terms of the agreement, OSE Immunotherapeutics will receive a €15 million upfront payment from Boehringer Ingelheim, and potential additional short-term milestones of up to €15 million upon initiation of a phase 1 clinical study. OSE Immunotherapeutics stands to receive more than €1.1 billion upon reaching pre-specified development, commercialization and sales milestones, plus royalties on worldwide net sales

On April 4, 2018 Daiichi Sankyo Company, Limited (hereafter, Daiichi Sankyo) and DarwinHealth reported they have entered into a research agreement providing Daiichi Sankyo with exclusive access to DarwinHealth’s proprietary novel cancer target database in order to identify potential new targets for cancer drug development (Press release, Daiichi Sankyo, APR 4, 2018, View Source [SID1234525189]).

DarwinHealth’s proprietary database and technology were created to identify critical mechanisms linked to tumor dependencies and maintenance beyond genetic mutations, and include information on Master Regulators of specific tumor subtypes, as well as direct upstream modulators (both necessary for cancer cell maintenance) across more than 35 tumor and 90 tumor subtypes.

"The purpose of this agreement is to identify novel, high-value cancer targets that can subsequently be prioritized and undergo rigorous experimental validation to drive drug development for a new generation of anti-cancer therapies that would be designed, developed, and owned by Daiichi Sankyo," said Gideon Bosker, MD, Chief Executive Officer, DarwinHealth.

DarwinHealth will receive an upfront payment and has the potential to receive development and commercialization milestone payments should specified events occur relating to DarwinHealth’s novel cancer targets. Daiichi Sankyo will receive exclusive access to DarwinHealth’s novel cancer target database for a predetermined amount of time with an option to extend. Financial terms of the agreement were not disclosed.

We believe that the combination of both molecular and computational techniques used by DarwinHealth coupled with the expertise of our scientists in designing small molecules and antibodies may offer a disruptive approach to accelerating the discovery of precision-medicine cancer compounds," said Antoine Yver, MD, MSc, Executive Vice President and Global Head, Oncology Research and Development, Daiichi Sankyo. "This new agreement is a natural next step in expanding our current ongoing translational research collaboration and we look forward to working with DarwinHealth to further science to create meaningful treatments for patients with cancer."

"The novel cancer targets will be selected and prioritized based on their role as either Master Regulators (MRs) or their most specific Master Regulator Upstream Modulators (MRUMs) within a tumor-specific checkpoint module," said Professor Andrea Califano, Co-Founder and Chairman of Scientific and Medical Advisory Board, DarwinHealth. "Therefore, they are expected to represent highly valuable targets for anti-tumor therapy, cancer drug design, and preclinical development."

On April 4, 2018 Arvinas LLC, a private biotechnology company creating a new class of drugs based on protein degradation, reported the closing of a $55 million Series C financing (Press release, Arvinas, APR 4, 2018, View Source [SID1234529237]). The financing was led by new investor Nextech Invest, with participation from additional new investors Deerfield Management, Hillhouse Capital, and Sirona Capital. All existing investors also participated in this financing round, including Canaan Partners, 5AM Ventures, RA Capital Management, OrbiMed, and New Leaf Venture Partners.

Proceeds from the financing will support the advancement of the Company’s two lead programs toward clinical investigation. The two programs, which target the androgen receptor for castration resistant prostate cancer and the estrogen receptor for ER+ positive breast cancer, both nominated orally available clinical candidates in the fourth quarter of 2017. These proceeds will also advance the Company’s early stage oncology pipeline, CNS pipeline, and efforts on undruggable targets.

"This past year has been exciting for us with two clinical candidate nominations, the expansion of our collaboration with Genentech and the announcement of a new collaboration with Pfizer," said John Houston, Ph.D., President and Chief Executive Officer of Arvinas. "With this additional financial support from existing and new investors who believe in our innovative protein degradation platform, we will continue executing on our strategy of progressing our lead programs to the clinic, expanding the use of the platform outside of oncology, and tackling undruggable targets."

In connection with the financing, Jakob Loven, Ph.D., partner with Nextech Invest, will join the Arvinas board of directors.

"The Arvinas PROTAC platform is an elegant, novel therapeutic modality that circumvents delivery challenges associated with existing therapeutic approaches to eliminate protein function, and Arvinas has proven to be the clear leader in developing a new era of targeted medicines using its protein degradation technology," said Dr. Loven.

The Company’s PROTAC Platform offers potential improvements over traditional small molecule inhibitors by using the cell’s natural and selective ubiquitin proteasome system to degrade disease-causing proteins. By removing target proteins directly rather than simply inhibiting them, PROTACs can provide multiple advantages over small molecule inhibitors which can require high systemic exposure to achieve sufficient inhibition, often resulting in toxic side effects and eventual drug resistance. With multiple protein targets, Arvinas’ PROTAC platform has demonstrated that a transient binding event at a range of binding sites and affinities can translate into very potent degradation of the target protein.

On April 4, 2018 AstraZeneca and MedImmune, its global biologics research and development arm, reported it will present updates from their early and late stage oncology pipelines at two major congresses this month.

Dave Fredrickson, Executive Vice President, Head of Oncology Business Unit said: "Building on major regulatory approvals in the first quarter of 2018, AstraZeneca continues to deliver strong results from our innovative science and accelerated development programmes in oncology. At ELCC, we are sharing new data from two pivotal trials in lung cancer that will help inform treatment strategies for patients who, until now, have had very few options. At the AACR (Free AACR Whitepaper) meeting, we will share pioneering early science across multiple tumour types."

ELCC

As part of the ‘Best of ELCC’ sessions, AstraZeneca will present post-progression outcomes from the FLAURA trial of Tagrisso versus the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) erlotinib or gefitinib in 1st-line EGFR mutation-positive NSCLC (Abstract #128O). In addition, patient-reported outcomes data will also be presented from the FLAURA trial, showing improvements in key symptoms, supporting the potential use of Tagrisso in this setting (Abstract #139PD).

Patient-reported outcomes will be presented from the PACIFIC trial of Imfinzi in unresectable, Stage III NSCLC (Abstract #703), following its approval in the US for this indication.

AACR annual meeting

DNA Damage Response (DDR)

AstraZeneca will present data on its expanded portfolio of potential medicines which exploit DDR dependencies to selectively kill cancer cells across multiple tumour types. The first-in-class PARP inhibitor, Lynparza, will report final overall survival data from the pivotal OlympiAD trial in BRCA-mutated metastatic breast cancer (Abstract #CT038). Data exploring the clinical properties of Lynparza and four other PARP inhibitors will illustrate clinical efficacy and safety profiles (Abstract #LB-273/17).

New data will also be presented on AZD6738, an Ataxia Telangiectasia and Rad3-related (ATR) inhibitor (Abstracts #CT026/19, #LB-263/7 and #337/18) and AZD0156, a first-in-class inhibitor of Ataxia telangiectasia mutated (ATM) (Abstract #4909/5).

Immuno-Oncology (IO)

A series of presentations will share new insights into the science of Imfinzi, including IO-IO combination data from Study 006 (Abstract #CT113) and Study 10 (Abstract #CT113) in 2nd-line NSCLC patient populations.

Beyond Imfinzi, MedImmune will feature progress in its early IO pipeline, including the novel bispecific antibody MEDI5752, designed to target dual checkpoints on immune cells and leverage the synergistic potential of combined mechanisms in immunotherapy (Abstract #2776/9).

Tumour Drivers & Resistance

Data on AZD4573, a CDK9 inhibitor, will demonstrate rapid cell-death induction in haematological tumour models through depletion of MCL1 (Abstract #310/17). And early monotherapy and combination data on the novel ERK inhibitor AZD0364, (Abstract #1647/2) will show its effect on KRAS-mutated tumours when used in combination with MEK inhibitor, selumetinib (Abstract #1856/14).

Crowd-sourcing combinations

AstraZeneca is presenting the results of the DREAM challenge, an open competition combining crowd-sourcing and the application of machine learning to generate new algorithms that predict the best therapeutic combinations for treating different types of cancer (Abstract #3886/5).

About Pegzilarginase (AEB1102) in Arginase 1 Deficiency
Pegzilarginase is an enhanced human arginase that enzymatically degrades the amino acid arginine. Aeglea is developing pegzilarginase for the treatment of patients with Arginase 1 Deficiency, a debilitating urea cycle disorder caused by deficiency of a key arginine metabolizing enzyme that leads to severe and progressive hyperargininemia-related neurological abnormalities, hyperammonemia and early mortality. Pegzilarginase is intended for use as an enzyme replacement therapy in patients to reduce elevated blood arginine levels. The Company’s Phase 1 data demonstrated that pegzilarginase reduced blood arginine levels into the normal range, supporting its mechanism of action.
