"We are continuing to make significant progress in our Phase 1/1b trial, which is designed to rapidly identify the diseases where our lead product candidate, CPI-444, has the greatest potential both as a single agent and in combination with atezolizumab," said Richard A. Miller, M.D., co-founder, president and chief executive officer of Corvus. "This strategic design has allowed us to identify four cohorts for expansion based on the demonstration of anti-tumor activity in renal cell cancer and non-small cell lung cancer, especially in patients that are resistant or refractory to prior treatment with anti-PD(L)-1 antibodies, and whose tumors are PDL-1 negative, an extremely difficult to treat patient population. We look forward to presenting additional clinical data from these cohorts in an oral presentation at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in June 2017."

RECENT ACHIEVEMENTS AND UPCOMING MILESTONES
Clinical & Preclinical Development

Expanded four cohorts from 14 to 26 patients in the ongoing disease-specific expansion part of the Phase 1/1b clinical study of the Company’s lead oral checkpoint inhibitor, CPI-444. The expanded cohorts include treatment with both CPI-444 as a single agent and in combination with atezolizumab (Tecentriq), an anti-PD-L1 antibody, in renal cell cancer (RCC) and non-small cell lung cancer (NSCLC).
Presented interim safety data on 113 patients and efficacy data for 96 patients enrolled the Company’s Phase 1/1b study at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2017. The data showed that treatment with CPI-444 was well tolerated, provided disease control and induced tumor regression in a number of patients with extensive disease, especially in patients who were resistant/refractory to prior treatment with anti-PD(L)-1 antibodies.
Plan to present clinical data from the four disease expansion cohorts in both RCC and NSCLC at the ASCO (Free ASCO Whitepaper) Annual Meeting in June 2017.
Continued to progress anti-CD73 antibody and ITK inhibitor programs toward Phase 1 study initiation in 2018.
CORPORATE DEVELOPMENT

On May 1, 2017, Corvus expanded its collaboration agreement with Genentech, a member of the Roche Group. Under the new agreement, CPI-444 administered in combination with atezolizumab (Tecentriq) will be evaluated in a Phase 1b/2 randomized, controlled clinical study as second-line therapy in patients with non-small cell lung cancer (NSCLC) who are resistant/refractory to prior therapy with an anti PD(L)-1 antibody. It is anticipated that the study will enroll up to 65 patients in the treatment arm. Genentech will manage study operations for the Phase 1b/2 trial, which is expected to begin enrolling patients in the second half of 2017. Corvus retains global development and commercialization rights to CPI-444.
FINANCIAL RESULTS

At March 31, 2017, Corvus had cash, cash equivalents and marketable securities totaling $122.1 million. This compared to cash, cash equivalents and marketable securities of $134.9 million at December 31, 2016.

Research and development expenses for the three months ended March 31, 2017 totaled $13.5 million compared to $5.4 million for the same period in 2016. The increase of $8.1 million was primarily due to an increase of $2.1 million in outside costs for the Phase 1/1b clinical trial for CPI-444, an increase of $1.7 million in drug manufacturing costs for our anti-CD73 antibody program, an increase of $0.8 million in personnel and related costs associated with higher headcount and a $3.0 million milestone payment made to Vernalis plc pursuant to our license agreement.

General and administrative expenses for the three months ended March 31, 2017 totaled $2.7 million compared to $1.0 million for the same period in 2016. The increase of $1.7 million was primarily due to an increase of $0.9 million in personnel and associated costs, primarily due to an increase in headcount and a $0.5 million increase in legal and accounting costs.

The net loss for the three months ended March 31, 2017 was $16.0 million compared to $6.4 million for the same period in 2016. Total stock compensation expense for the three months ended March 31, 2017 was $1.5 million compared to $0.4 million for the same period in 2016.

On May 4, 2017 Eleven Biotherapeutics, Inc. (NASDAQ:EBIO), a late-stage clinical oncology company advancing a broad pipeline of novel product candidates based on its Targeted Protein Therapeutics (TPTs) platform, reported financial results for the quarter ended March 31, 2017, and provided a corporate update (Press release, Eleven Biotherapeutics, MAY 4, 2017, View Source [SID1234518830]).

"During our first quarter of 2017, we made meaningful progress, advancing our Phase 3 registration clinical trial of Vicinium and continuing development efforts with Proxinium and VB6-845d," said Stephen Hurly, President and Chief Executive Officer of Eleven Biotherapeutics. "Importantly, we also presented new preclinical data supporting the potential of our locally- and systemically-administered drug candidates not just as monotherapies, but also in combination with immuno-oncology products, including checkpoint inhibitors. These results accord with our clinical development strategies, and we look forward to further exploring TPTs as new medicines with the potential to offer considerable improvements over existing options."

First Quarter and Recent Business Highlights and Anticipated Upcoming Milestones:

Vicinium: Vicinium is a single protein anti-epithelial cell adhesion molecule (anti-EpCAM) antibody fragment fused with Pseudomonas Exotoxin A (ETA) that is designed to specifically target and deliver a potent anti-cancer payload directly into tumor cells. Vicinium is currently in a Phase 3 registration clinical trial for the treatment of high-grade non-muscle invasive bladder cancer (NMIBC) in subjects who have previously received two courses of Bacillus Calmette-Guérin (BCG) and whose disease is now BCG-unresponsive.

Complete enrollment for Phase 3 registration clinical trial expected in second half of 2017
Topline data from Phase 3 registration clinical trial expected in 2018
Proxinium: Proxinium is a single protein anti-EpCAM antibody fragment fused with ETA for the treatment of late-stage squamous cell carcinoma of the head and neck (SCCHN). Proxinium has received Orphan Drug Designation from the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA), and Fast Track designation from the FDA. Proxinium has demonstrated anti-tumor activity in prior Phase 1 and 2 clinical trials.

Initiation of Phase 1/2a clinical trial evaluating Proxinium in combination with a checkpoint inhibitor expected in second half of 2017
At the American Association of Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting in April, Eleven presented new preclinical results with VB4-845, the active pharmaceutical ingredient used to formulate both Vicinium and Proxinium. Data suggest that VB4-845 induces the expression of HMGB1 in tumor treated cells; HMGB1 is one of three damage-associated molecular patterns (DAMPs) indicative of immunogenic cell death (ICD). Eleven has previously disclosed observations of the other two DAMPs markers – cell surface expression of calreticulin and extracellular release of ATP – following treatment with VB4-845. Together, these results suggest that product candidates formulated with VB4-845 are capable of driving host anti-tumor immune responses that can potentiate the activity of immuno-oncology agents.

As part of the same poster presentation, Eleven shared data from a preclinical model in patient-derived xenograft tumor-bearing mice reconstituted with a human immune system, which was used to assess the combination of intratumoral injection of VB4-845 with the anti-PD1 antibody, nivolumab. Treatment with VB4-845 alone suppressed the growth of injected tumors, while monotherapy nivolumab had little effect. In contralateral, non-injected tumors, responses from mice treated with both VB4-845 and nivolumab were more pronounced than responses in mice treated with either product as a monotherapy. Based on these results, Eleven believes that VB4-845 killing of tumor cells could facilitate and augment checkpoint inhibitor anti-tumor activity.

Systemically-administered TPT Pipeline: Eleven’s initial systemically-administered TPTs leverage a proprietary, highly potent, de-immunized, plant toxin, deBouganin. DeBouganin has picomolar killing of cancer cells and may be effective against cancer stem cells. In preclinical studies, deBouganin demonstrated the ability to avoid multi-drug resistance mechanisms that can decrease the efficacy of small molecule payloads. Based on these results, Eleven believes that deBouganin-based therapies may be effective against a wide spectrum of cancers.

Investigational New Drug Application (IND) submission for VB6-845d planned for first quarter of 2018
At the AACR (Free AACR Whitepaper) Annual Meeting, Eleven presented preclinical data suggesting that its deBouganin payload is capable of effectively killing tumor cells that are resistant to treatment with antibody drug conjugates (ADCs) composed of DM-1 and MMAE payloads when conjugated to the same monoclonal antibody, trastuzumab. The Company believes this is due, in part, to deBouganin’s lack of sensitivity to both the multidrug resistance pumps and the changes in phosphorylation status of proteins involved in cell proliferation and survival that allow some cancers to escape the action of anti-mitotic ADCs.

Corporate: Eleven further expanded its internal clinical development team with two key hires: Gary Conboy as Executive Director, Clinical Sciences and Mary Rohrer as Associate Director, Clinical Operations.

First Quarter 2017 Financial Results:

Cash Position: Cash and cash equivalents were $20.3 million as of March 31, 2017, compared to $25.3 million as of December 31, 2016.
Revenue: Revenue was $0.4 million for the three months ended March 31, 2017, compared to $0.2 million for the same period in 2016. This increase was due to revenue recognized from the License Agreement (License Agreement) with F. Hoffmann-La Roche Ltd and Hoffmann-La Roche Inc. (Roche).
R&D Expenses: Research and development expenses were $2.9 million for the three months ended March 31, 2017, compared to $4.6 million for the same period in 2016. The decrease was due primarily to a reduction in isunakinra and EBI-031 related development expenses, partially offset by an increase in Vicinium related development expenses.
G&A Expenses: General and administrative expenses were $2.2 million for the three months ended March 31, 2017, compared to $2.1 million for the same period in 2016.
Net Loss: Net loss was $6.1 million, or $0.25 per share, for the three months ended March 31, 2017, compared to net loss of $7.6 million, or $0.39 per share, for the same period in 2016.
Financial Guidance: Based on current operating plans, Eleven expects to have cash to fund research and development programs and operations into early 2018.

"Although solid tumor cancers are generally rare in children, brain and spinal cord tumors are the third most common type of childhood cancer," said Dr. Stewart Goldman, Professor of Pediatrics at the Ann & Robert H. Lurie Children Hospital of Chicago. "In order to make a meaningful impact in the lives of these children, we need ongoing research to test the safety and feasibility of potential treatments. We are pleased to see trials testing TTFields in this underserved population."

The first trial, sponsored by the Pediatric Brain Tumor Consortium in collaboration with the National Cancer Institute, will study the feasibility of using TTFields for children with recurrent or progressive suptratentorial high-grade glioma and ependymoma. This study will primarily assess patients’ compliance and number of treatment-related toxicities with secondary outcome measures including the response rate and event-free survival. This trial is actively recruiting an estimated 25 patients.

In the second study, the safety, tolerability and preliminary efficacy of TTFields will be tested in pediatric high-grade gliomas in two cohorts. The initial cohort of patients will receive TTFields alone and will consist of children with recurrent high-grade gliomas. The second cohort of patients will receive TTFields in combination with temozolomide and bevacizumab and is open to children with both newly diagnosed and recurrent gliomas. The trial, sponsored by Hackensack University Medical Center, is actively recruiting and is estimated to enroll 12 patients.

For more information on the trial designs, visit clinicaltrials.gov and reference NCT03033992 and NCT03128047. Treatment with TTFields is not approved for the treatment of pediatric gliomas by the U.S. Food and Drug Administration. The safety and effectiveness of TTFields therapy for pediatric gliomas has not been established.

On May 4, 2017 Syros Pharmaceuticals (NASDAQ: SYRS), a biopharmaceutical company pioneering the discovery and development of medicines to control the expression of disease-driving genes, reported new data generated using its gene control platform, including the discovery of 14 new drug targets in triple negative breast cancer (Press release, Syros Pharmaceuticals, MAY 4, 2017, View Source [SID1234518828]). These discoveries demonstrate the power of Syros’ pioneering approach for systematically analyzing regulatory regions of the genome to identify novel targets for defined subsets of patients with diseases that have eluded other genomics-based approaches. These data were presented at the IMPAKT 2017 Breast Cancer Conference in Brussels, Belgium.

"Targeted drug discovery in cancer has focused on mutations in protein-coding regions of the genome, and while some cancers have been well served by this approach, many other cancers, including triple negative breast cancer, remain unaddressed," said Eric Olson, Ph.D., Chief Scientific Officer of Syros. "By analyzing the non-coding regulatory region of the genome of tumor cells, we have uncovered new targets in subsets of triple negative breast cancer. Our focus on the regulatory genome, coupled with our expertise in drugging transcriptional targets to control the expression of genes, positions us to develop a new wave of genomic-based medicines for patients with diseases that have remained beyond the reach of other targeted approaches."

Using its proprietary gene control platform to analyze the regulatory genomes from 43 breast cancer patients’ tissue samples, Syros scientists identified highly specialized regions of non-coding regulatory DNA, known as super-enhancers, that drive the expression of genes critical for tumor growth and survival in defined subsets of breast cancer patients. Analysis of the super-enhancers and their associated genes revealed:

Known cancer drivers and patient subsets, with HER2+ patients having a super-enhancer associated with the HER2 gene and ER+ patients having a super-enhancer associated with the ESR1 gene, providing validation that super-enhancer analysis can be used to identify clinically relevant disease drivers in defined patient subsets.
Enhancer-linked genes that were validated as essential for triple negative tumor cell proliferation by CRISPR-mediated gene disruption.

Of those genes, 14 code for newly identified drug targets for triple negative breast cancer across a range of druggable target types, including enzymes, surface receptors, and signaling and metabolic proteins.
A super-enhancer associated with the RARA gene that is predictive of response to SY-1425, a first-in-class selective retinoic acid receptor alpha (RARα) agonist, in multiple preclinical models of breast cancer, including those resistant to treatment with standard-of-care therapies. Notably, the RARA super-enhancer is present across known subtypes of breast cancer, and Syros estimates it is present in about 35 percent of breast cancer patients. SY-1425 is currently in a Phase 2 clinical trial for patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) who are positive for biomarkers for super-enhancers linked to RARA pathway-associated genes, including RARA and IRF8. Upon achieving clinical proof-of-concept in that trial, Syros plans to expand development of SY-1425 into genomically defined subsets of breast cancer patients.

Syros’ drug discovery and development platform is the first to focus solely on the regulatory genome to systematically and efficiently identify disease-causing alterations in gene expression and create medicines to selectively target transcription to control the expression of genes with the aim of treating cancer, as well as autoimmune and rare genetic diseases. Using its platform, Syros is advancing a growing pipeline of drug candidates, including SY-1425 and SY-1365, a first-in-class selective inhibitor of cyclin-dependent kinase 7 (CDK7), that is on track to begin a Phase 1 clinical trial in the second quarter of this year in patients with transcriptionally dependent solid tumors, including triple negative breast, small cell lung and ovarian cancers.
