Klaus Edvardsen, Nykode’s Chief Development Officer, stated: "The data presented today show that VB10.NEO induces a broad, strong and long-lasting CD8 T cell response against patient-specific tumors, in addition to being safe and well-tolerated in combination with other anti-cancer treatments. The data continue to substantiate our differentiated platform technology and support its huge potential within individualized cancer treatments. We are happy to have such strong partners as Genentech for continued development."

Summary of Safety Results

41 patients were dosed with VB10.NEO. The data show that VB10.NEO was generally safe and well-tolerated in patients with solid tumors when administered in combination with various anti-cancer treatments. The most common adverse events reported were fatigue (34%) and diarrhea (27%). The observed adverse events are generally consistent with the known safety profiles of checkpoint inhibitors, chemotherapy, as well as other targeted cancer therapies, with no overt signs of add-on toxicity.

Summary of Immunogenicity Results

22 patients were included in the interim analysis. Blood samples were collected at baseline, week 11, 22, 34 and 54, to assess immune response to individual neoepitopes by ELISpot.

A neoantigen-specific immune response was observed in all patients (ranging from 3-20 neoepitopes)
A vaccine-induced T cell response was observed in 95% of patients, inducing expansion of both novel and pre-existing T cells
The responses were broad and the majority of the neoepitopes included in the vaccines were immunogenic
Polyfunctional Th1 CD4 and Tc1 CD8 T cell responses were observed
Ranging from 53% to 100% (or 85% on average) of the neoepitopes induced a CD8 T cell response. Cytotoxic CD8 T cells are known to be important for killing tumor cells
The breadth and magnitude of immune response increased upon multiple vaccinations
Responses to the majority of the neoepitopes were maintained for at least one year

About the Phase 1/2a Trial
VB N-01 is an open-label first-in-human Phase 1/2a study to evaluate safety, feasibility and efficacy of multiple dosing with individualized VB10.NEO or VB10.NEO and bempegaldesleukin (NKTR-214) immunotherapy in patients with locally advanced or metastatic melanoma, NSCLC, clear renal cell carcinoma, urothelial cancer or squamous cell carcinoma of head and neck, who did not reach complete responses with current standard of care immune checkpoint blockade. More information is available at clinicaltrials.gov: identifier NCT03548467.

About VB10.NEO
VB10.NEO is a proprietary individualized DNA-based neoantigen vaccine in development for the treatment of locally advanced or metastatic solid tumors under an exclusive, worldwide clinical collaboration with Genentech, a member of the Roche group. The vaccine is designed to be produced on-demand according to the neoantigen profile of an individual patient. Neoantigens are proteins generated by tumor-specific mutations not present in normal tissues and are thus an attractive target for cancer immunotherapy as they may be recognized as foreign by the immune system.

Nykode is currently conducting two clinical studies evaluating VB10.NEO: VB N-01 and VB N-02. VB N-01 is an open-label Phase 1/2a basket study to evaluate the safety and efficacy of multiple dosing with VB10.NEO in patients with locally advanced or metastatic cancer (NCT03548467). VB N-02 is an open-label Phase 1B, dose-escalation study of the safety- and antigen-specific immune responses elicited by VB10.NEO in combination with Roche’s checkpoint inhibitor atezolizumab in patients with locally advanced and metastatic tumors (NCT05018273).

On October 26, 2022 Galera Therapeutics, Inc. (Nasdaq: GRTX), a clinical-stage biopharmaceutical company focused on developing and commercializing a pipeline of novel, proprietary therapeutics that have the potential to transform radiotherapy in cancer, reported the presentation of one-year tumor and renal function outcomes data from its Phase 3 ROMAN trial of avasopasem manganese 90 mg for radiotherapy-induced severe oral mucositis (SOM), as well as topline results from a recently completed meta-analysis of the ROMAN and GT-201 SOM trial results, at the 2022 American Society for Radiation Oncology (ASTRO) Annual Meeting (Press release, Galera Therapeutics, OCT 26, 2022, View Source [SID1234622391]). Final data from its Phase 2 AESOP trial of avasopasem for radiotherapy-induced esophagitis were also presented today in a separate session. In addition, poster presentations during ASTRO highlighted the completed Phase 2 EUSOM trial of avasopasem for SOM in Europe and the ongoing GRECO-1 trial of rucosopasem for non-small cell lung cancer. The presentations and posters are currently available in the ASTRO digital program.

Highlights from the Phase 3 ROMAN data presented at ASTRO:

After one-year follow-up, patients with locally advanced head and neck cancer treated with avasopasem in combination with the standard-of-care regimen (intensity-modulated radiation therapy (IMRT) + cisplatin) demonstrated comparable tumor outcomes and overall survival to patients in the placebo arm.
Patients treated with avasopasem in combination with IMRT + cisplatin had a 10 percent incidence of chronic kidney disease (CKD) after one year of post treatment follow-up, compared to 20 percent of patients in the placebo arm (p=0.0043). CKD (eGFR <60) is a known toxicity risk with cisplatin for these patients and the results highlight success on a predefined exploratory endpoint of renal function. The prospective exploration of this potential benefit of avasopasem was driven by published preclinical data and a post hoc assessment of patients from the GT-201 trial presented at the 2020 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting.
"The ROMAN one-year follow-up data show that avasopasem can protect head and neck cancer patients from severe oral mucositis without affecting the treatment benefit of standard-of-care chemoradiotherapy," said Dr. Carryn Anderson, Clinical Associate Professor of Radiation Oncology at the University of Iowa. "Treatment with avasopasem also significantly reduced the likelihood of patients developing cisplatin-related chronic kidney disease compared to placebo at one-year follow-up, suggesting avasopasem can reduce cisplatin renal toxicities and greatly improve patient quality of life."

In addition to the ROMAN long-term endpoints, a meta-analysis of Galera’s two randomized placebo-controlled trials (ROMAN and GT-201; n=551) was included in Dr. Anderson’s ASTRO presentation; these results reinforced that avasopasem therapy resulted in clinically meaningful reductions in radiotherapy-induced SOM, including a significant reduction in the incidence, duration, onset and severity of SOM compared to placebo.

"The data presented today affirm our belief that avasopasem is providing real benefit for patients with head and neck cancer undergoing the current standard of care," said Mel Sorensen, M.D., Galera’s President and CEO. "We look forward to submitting the NDA to the FDA by the end of 2022 with the intention of bringing avasopasem to patients as the first FDA-approved drug for radiotherapy-induced SOM."

About Severe Oral Mucositis (SOM)

Approximately 42,000 patients with head and neck cancer undergo standard-of-care radiotherapy every year in the U.S. and are at risk of experiencing SOM. In patients with head and neck cancer, radiotherapy is a mainstay of treatment. Approximately 70 percent of patients receiving radiotherapy for head and neck cancer develop SOM, defined by the inability to eat solid food or drink liquids. The impact on patients who develop SOM is substantial, particularly when hospitalization and/or surgical placement of PEG tubes to maintain nutrition and hydration are required. SOM can adversely affect cancer treatment outcomes by causing interruptions in radiotherapy, which may compromise the otherwise good prognosis for tumor control in many of these patients. There is currently no drug approved to prevent or treat SOM for these patients.

About Avasopasem

Avasopasem manganese (avasopasem, or GC4419) is a selective small molecule dismutase mimetic in development for the reduction of radiotherapy-induced severe oral mucositis (SOM) in patients with locally advanced head and neck cancer (HNC) and for the reduction of radiotherapy-induced esophagitis in patients with lung cancer. The FDA has granted Fast Track and Breakthrough Therapy designations to avasopasem for the reduction of SOM induced by radiotherapy, with or without systemic therapy.

Trilaciclib, an IV-administered transient CDK4/6 inhibitor, is a first-in-class therapy designed to preserve bone marrow and immune system function during chemotherapy to improve patient outcomes.

"Pretreatment with trilaciclib may improve the therapeutic potential of lurbinectedin, another important medication for SCLC, in multiple ways," said Jared Weiss, M.D., Professor of Medicine, Division of Oncology, Lineberger Comprehensive Cancer Center at the University of North Carolina Chapel Hill, NC and principal investigator in this study. "Trilaciclib is a proven myeloprotective agent, but studies to date have only assessed it in the context of topotecan-containing and platinum/etoposide-containing chemotherapeutic regimens. Lurbinectedin is effective, but also highly myelosuppressive, which is particularly problematic given recent data that clarify the importance of maintaining adequate exposure for efficacy. The opportunity for immunological synergy with lurbinectedin – which potently suppresses myeloid derived suppressor cells (MDSCs) – is also evident given data that suggest trilaciclib’s ability to induce novel T cell clonality, improve the CD8+ T cell/Treg ratio, and increase antigen expression and presentation."

This is a prospective, non-randomized, single-arm Phase 2 study, to evaluate trilaciclib administered intravenously prior to lurbinectedin in approximately 30 subjects with platinum refractory ES-SCLC. Patients will receive trilaciclib and lurbinectedin on day one of each 21-day cycle until discontinuation or disease progression.

The primary endpoint is the rate of grade 4 neutropenia in any cycle when trilaciclib is administered prior to lurbinectedin in subjects with extensive stage small cell lung cancer (ES-SCLC). Secondary endpoints include mean duration (days) of grade 4 neutropenia in cycle 1, overall survival (OS), progression-free survival (PFS), overall rate of response (ORR), quality of life assessments, and the use of secondary/reactive supportive measures including G-CSF administration.

About Small Cell Lung Cancer
In the United States, about 29,000 cases of small cell lung cancer (SCLC) are diagnosed each year. SCLC, one of the two main types of lung cancer, accounts for about 10% to 15% of all lung cancers. SCLC is an aggressive disease and tends to grow and spread faster than NSCLC. It is usually asymptomatic; once symptoms do appear, it often indicates that the cancer has spread to other parts of the body. About 70% of people with SCLC will have cancer that has metastasized at the time they are diagnosed. The severity of symptoms usually increases with increased cancer growth and spread. From the time of diagnosis, the general 5-year survival rate for people with SCLC is 6%. The five-year survival rates for limited-stage (the cancer is confined to one side of the chest) SCLC is 12% to 15%, and for extensive stage (cancer has spread to the other lung and beyond), survival rates are less than 2%. Chemotherapy is the most common treatment for SCLC.

On October 26, 2022 Orionis Biosciences, a life sciences company pioneering innovation of highly selective and tunable therapeutics for cancer and beyond, reported that it will present preclinical data supporting its Allo-GlueTM protein degradation platform for discovery and rational design of small molecule molecular glues at the 5th Annual Targeted Protein Degradation Summit, taking place October 25 – 28 in Boston (Press release, Orionis Biosciences, OCT 26, 2022, View Source [SID1234622388]). The data include platform achievements for ligase-centric and target-centric discovery of molecular glue compounds with potential to modulate previously intractable disease targets.

"Molecular glues have the potential to greatly extend the treatment of challenging diseases like cancer, and there is vast untapped power in this modality. A lack of systematic, scalable discovery and design approaches to molecular glues has, however, limited the field," said Riccardo Sabatini, Ph.D., Chief Data Scientist at Orionis. "Today we are presenting new data that demonstrate the ability of Orionis’ proprietary Allo-GlueTM platform to transform glue discovery into a genome-scale, high throughput and rational discovery paradigm. Our large-scale interrogation of small molecule-triggered protein-protein interactions makes it abundantly clear that molecular glue mechanisms are more common than previously appreciated. Clearly, this presents a large and exciting space for chemistry innovation."

The Allo-Glue platform can interrogate more than 18,000 target proteins simultaneously — virtually the entire human proteome — as well as diverse and privileged chemical libraries, at scale and in an unprecedented, unbiased manner across large number of targets and target classes, including traditionally intractable disease targets. To date, Orionis has mapped more than 150 million molecular glue interactions. This growing data set will provide the company with unique opportunities to further evolve and apply its novel numerical modelling approaches to the rational design of molecular glues.

To date, Orionis’ Allo-Glue platform has:

Identified multiple monovalent glues and targets for new ligases beyond the E3 ligase cereblon: A series of molecules have demonstrated strong and highly selective target recruitment and degradation in preclinical studies, further validating the concept that drug-induced, selective degradation of proteins is achievable with multiple types of E3 ligases and targets
Established the feasibility of target-centric approaches to glue discovery, as exemplified by discovery of drug-like molecules for traditionally intractable oncology targets
Evolved and applied computational methods and machine learning models to rational expansion and design of new molecular glues
Details of today’s presentation are as follows:

5th Annual Targeted Protein Degradation, October 25-28, 2022, Boston, Massachusetts

Title: Monovalent Molecular Glues: Cereblon and Beyond
Date and Time: Wednesday, October 26, 5:00 p.m. ET
Presenter: Riccardo Sabatini, Chief Data Scientist, Orionis Bio
Last week Orionis announced a $55 million financing to support entry of its lead cancer immunotherapy programs into the clinic. In addition to its Allo-Glue molecules, Orionis is rapidly advancing a deep pipeline of biologics for the treatment of cancer based on its A-KineTM platform, which engineers target-selective, conditionally active cytokines designed to trigger anti-tumor immune responses even in cold tumors that lack prevalent immune involvement and are refractory to checkpoint inhibitor therapies. A-Kines aim to avoid the systemic toxicities observed with traditional cytokine therapies. The company anticipates IND submission and start of a Phase 1 study of a conditionally active cytokine, driven by its proprietary A-Kine platform, in 2023.

"We are all very excited about the continued progress the company is making with its multipronged technology and therapeutic approaches to currently hard to treat cancers. Our R&D engine has the potential to address some of the biggest challenges in drug discovery, including diseases beyond cancer," said Nikolai Kley, co-founder, President and Chief Executive Officer of Orionis Biosciences.
