MiNA Therapeutics Announces Initiation of Phase I Clinical Study of MTL‑CEBPA in Combination with anti-PD1 Checkpoint Inhibitor in Patients with Advanced Solid Tumours

On March 3, 2020 MiNA Therapeutics, the pioneer in RNA activation therapeutics, reported the initiation and first patient treated in TIMEPOINT, a global Phase 1/1b clinical study of MTL-CEBPA in combination with anti-PD1 checkpoint inhibitor pembrolizumab in patients with advanced solid tumours (Press release, MiNA Therapeutics, MAR 3, 2020, View Source [SID1234555141]). The study is designed to assess the safety, tolerability, pharmacology and clinical activity of MTL-CEBPA in combination with pembrolizumab in these patients. MTL-CEBPA is the first therapy to specifically up-regulate CCAAT/enhancer binding protein alpha (C/EBP-α), a transcription factor that acts as a master regulator of myeloid cell lineage determination and differentiation. The drug candidate is also being investigated in an ongoing multi-centre Phase 1b clinical trial in patients with advanced liver cancer in combination with sorafenib.

"Initiation of the Phase I TIMEPOINT clinical trial emphasizes the continued exploration of MTL-CEBPA, the first drug candidate that targets C/EBP-α, a master regulator of immune cells that play a critical role in tumour resistance," commented Robert Habib, CEO of MiNA Therapeutics. "We are excited to take the next step and test MTL‑CEBPA in additional cancer populations in a potentially synergistic combination with an anti-PD1 checkpoint inhibitor. We look forward to collaborating with our clinical investigators in evaluating this new combination."

The TIMEPOINT study consists of a dose-escalation followed by a dose expansion. MTL‑CEBPA will be administered as an intravenous infusion once weekly in cycles of three weeks of treatment followed by one week of rest. In pre-clinical studies MTL-CEBPA has been shown to improve the anti-tumour activity of anti-PD1 checkpoint inhibition by reducing immune suppression from dysregulated myeloid cells in the tumour microenvironment.

The single agent activity of MTL-CEBPA in 39 patients with advanced liver cancer was previously presented by investigators at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) 2019 Congress. MTL-CEBPA was found to be well tolerated, demonstrating pharmacodynamic target engagement and a reduction of suppressive immune cells in the tumour microenvironment. In addition, MTL-CEBPA demonstrated clear, synergistic activity in patients with liver cancer when also treated with sorafenib standard of care.

"MTL-CEBPA has shown real promise as a combination agent in patients with liver cancer and pre-clinical studies suggest that MTL-CEBPA may also be an attractive agent to enhance the benefits of checkpoint inhibitors," commented Professor Ruth Plummer, Clinical Professor of Experimental Medicine at the Clinical and Translational Research Institute, Newcastle University Centre for Cancer, and Chief Investigator of the study. "We are looking forward to evaluating this highly innovative combination treatment in the upcoming Phase I trial. We hope this combination could become an effective new treatment option for patients with solid tumour cancers."

About the TIMEPOINT Study

TIMEPOINT is a global Phase I/Ib clinical study in patients with solid tumour malignancies that will assess the safety and tolerability of MTL-CEBPA in combination with pembrolizumab in patients who are ineligible or resistant to standard therapies. The study has received clearance from the U.S. Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).

About MTL-CEBPA

MTL-CEBPA is the first therapy to specifically up-regulate CCAAT/enhancer binding protein alpha (C/EBP-α), a transcription factor that acts as a master regulator of myeloid cell lineage determination and differentiation. Dysregulated myeloid cells have been implicated in several diseases and identified as a critical barrier for many therapies to induce clinical responses in solid tumour cancers. In pre-clinical studies MTL-CEBPA has been shown to improve the anti-tumour activity of cancer therapies by targeting dysregulated myeloid cells and reducing their suppression in the tumour microenvironment.

PDC*line Pharma Announces the Administration of a First Patient With Its Therapeutic Cancer Vaccine Candidate (PDC*lung01) Targeting Non-small Cell Lung Cancer

On March 3, 2020 PDC*line Pharma, a clinical stage biotech company developing a new class of potent and scalable active immunotherapies for cancers, reported that the first patient was dosed with its innovative medicinal product candidate PDC*lung01 in a phase I/II trial in non-small cell lung cancer (NSCLC) (Press release, PDC Line Pharma, MAR 3, 2020, View Source [SID1234555139]). This patient is under the supervision of Dr. Anne Sibille, principal investigator for the Liege University Hospital (Belgium).

The objectives of the phase I/II trial (PDC-LUNG-101) are to assess the safety, tolerability, immunogenicity and preliminary clinical activity of the drug candidate, PDC*lung01, associated or not with anti-PD-1 treatment in NSCLC. A total of 62 evaluable HLA-A*02:01 positive NSCLC patients are expected in three clinical centers in Belgium and six in France.

PDC*lung01 is a cell suspension of a mix, in the same proportion, of seven active agents made of irradiated human plasmacytoïd dendritic cells (PDC*line) loaded separately with a distinct synthetic human leukocyte antigen serotype-restricted peptide (HLA-A*02:01) encoded by a tumour antigen. PDC*line is a potent professional antigen-presenting cell that is able to prime and boost the antitumor cytotoxic CD8+ T-cells in the patient’s immune system.

"We are delighted to have achieved this first important milestone in the clinical development of PDC*line Pharma with our lead cancer vaccine candidate," said Eric Halioua, president and CEO of PDC*line Pharma. "Based on preclinical studies there is a strong rationale for developing PDC*lung01 in this indication and we are currently exploring a number of additional indications, where our technology may provide potential benefit for patients."

"PDC*lung01 is an innovation in the field of cancer vaccines that appears particularly suitable for the treatment of NSCLC patients, an area where there is still a high unmet medical need," said Dr. Channa Debruyne, medical director of PDC*line Pharma.

About lung cancer
Worldwide, lung cancer is the most common malignancy for male patients and for both sexes combined (2.1 million new cases per year), and the third most common for female patients (after breast and colorectal cancers). Globally, deaths from lung cancer exceed those from any other cancer, with the number of lung-cancer-related deaths for 2018 estimated at 18.1 million; 18.4% of total cancer deaths. Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, representing 80% of cases.

About PDC*line Pharma’s technology

PDC*line’s biological features provide unique advantages:

A professional antigen-presenting cell line, much more potent than conventional dendritic cells in priming and expanding antitumor-specific cytotoxic CD8+ T cells (conventional tumor antigens and neoantigens)
While allogeneic, PDC*line is not rejected by the host immune system and can be injected several times to boost the immune response
Easily produced on a large scale, with a fully mastered and simple manufacturing process (use of bioreactors with a synthetic medium without growth, differentiation or activation factors)
Easy to use: after thawing, the same off-the-shelf product is used to treat the whole target population with a cancer type expressing the target antigens
Very versatile: tumor antigens can be provided by peptide loading, mRNA transfection or retrovirus transduction of PDC*line and the target population can be extended beyond HLA-A2 (currently used as it is expressed by 50% of the Caucasian population) by using other HLAs, either already expressed by PDC*line or added by genetic modification. Moreover, new candidates can be validated for new cancer indications in a few weeks, with ex vivo testing using human peripheral blood mononuclear cells (PBMC)
Synergizes with anti-PD-1 to activate antitumor CD8 T cells

VBI Vaccines Provides Update on Part A of Ongoing Phase 1/2a Study Demonstrating Overall Survival Benefit for VBI-1901 Vaccine Responders in Recurrent GBM Patients

On March 3, 2020 VBI Vaccines Inc. (NASDAQ: VBIV) ("VBI"), a commercial-stage biopharmaceutical company developing next-generation infectious disease and immuno-oncology vaccines, reported an update on Part A of the ongoing Phase 1/2a study of VBI-1901, the company’s cancer vaccine immunotherapeutic candidate, for the treatment of patients with recurrent glioblastoma (GBM) (Press release, VBI Vaccines, MAR 3, 2020, View Source [SID1234555138]). For patients who had an immunologic response to the vaccine, considered to be vaccine responders, the 12-month overall survival (OS) rate was 83% (n=5/6), compared to 33% for vaccine non-responders (n=3/9). Similarly, among patients evaluable for response and survival in Part A, vaccine responders saw a 6.25-month improvement in median OS (14.0 months) compared to vaccine non-responders (7.75 months). VBI-1901 continues to be safe and well-tolerated at all doses tested, with no safety signals observed.

"We remain encouraged by the data from this ongoing Phase 1/2a study of VBI-1901 in the recurrent GBM setting, a setting in which it has historically been incredibly difficult to show any benefit, especially with a monotherapy," said David E. Anderson, Ph.D., VBI’s Chief Scientific Officer. "The standard of care treatment in the recurrent GBM setting is not well defined, however, commonly-used regimens, including chemotherapy and VEGF-A inhibitors as monotherapy and in combination, have demonstrated 12-month OS rates below 50% with median OS around 8 to 12 months1. Moreover, these regimens often cause significant toxicity, poorly affecting quality of life for the individual. While the data generated for VBI-1901 is early, we continue to be optimistic as we work hard to provide any meaningful benefit to patients who currently have few treatment options."

Expanded immunologic, tumor imaging, and clinical data from the Phase 2a part of the study are expected in Q2 2020 – data from the VBI-1901 + GM-CSF arm – and Q4 2020 – data from the VBI-1901 + AS01B arm. Additionally, efforts are underway to define biomarkers that may help identify patients more likely to respond to VBI-1901.

About the Phase 1/2a Study Design
VBI’s two-part Phase 1/2a study is a multi-center, open-label, dose-escalation study of VBI-1901 in up to 38 patients with recurrent GBM:

Phase 1 (Part A)
Dose-escalation phase that defined the safety, tolerability, and optimal dose level of VBI-1901 adjuvanted with granulocyte-macrophage colony-stimulating factor (GM-CSF) in recurrent GBM patients, with any number of prior recurrences.
This phase enrolled 18 recurrent GBM patients across three dose cohorts of VBI-1901: 0.4 µg, 2.0 µg, and 10.0 µg.
Enrollment completed in December 2018.
Phase 2a (Part B)
Subsequent extension of the optimal dose level, 10.0 µg, as defined in the Part A dose escalation phase.
This phase is a two-arm study, enrolling 10 first-recurrent GBM patients in each arm, assessing 10.0 µg of VBI-1901 in combination with either GM-CSF or GSK’s proprietary AS01B adjuvant system as immunomodulatory adjuvants.
Enrollment in both study arms is ongoing.
VBI-1901 is administered intradermally when adjuvanted with GM-CSF and will be administered intramuscularly when adjuvanted with AS01B adjuvant system. Patients will receive the vaccine immunotherapeutic every four weeks until tumor progression.

Additional information, including a detailed description of the study design, eligibility criteria, and investigator sites, is available at ClinicalTrials.gov using identifier NCT03382977.

Transgene and BioInvent have submitted the first clinical trial application for BT-001, and the first-in-human trial is expected to start before the end of 2020 in Europe and the USA.

BT-001 is a multifunctional oncolytic virus being co-developed by Transgene and BioInvent. It is based on Transgene’s Invir.IO platform and patented, large-capacity VVcopTK-RR- oncolytic virus. BT-001 has been engineered to encode a Treg-depleting, anti-CTLA4 antibody derived from BioInvent’s proprietary n-CoDeR/F.I.R.S.T platforms, as well as the cytokine GM-CSF.

Both the oncolytic and the anti-CTLA4 therapeutic strategies that underpin BT-001 have demonstrated activity in humans based on their ability to induce a fundamental change in the tumor microenvironment and anti-tumoral activity. Looking at the clinical landscape, BT-001 could either be used as a monotherapy or be associated with standard of care immunotherapy options such as anti-PD1/anti-PD-L1 therapies.

"In preclinical models, BT-001 has demonstrated the benefits of its multiple mechanisms of action as well as the potential to deliver significantly improved tolerability when compared to the anti-PD-1/anti-CTLA4 combination therapies currently available," said Björn Frendéus, Ph.D., Chief Scientific Officer of BioInvent. "We believe that the potential to combine anti-CTLA4, anti-PD-1/PD-L1 and oncolytic immunotherapy could change the treatment paradigm for multiple solid tumors, and we are very much looking forward to investigate BT-001 in its first-in-human study, which is planned to start before the end of 2020."

"With BT-001, we are looking to combine Transgene’s potent oncolytic virus with the local production of a high concentration of an anti-CTLA4 antibody. We believe that BT-001 will have an improved tolerability due to its ability to generate high concentrations of the antibody in the tumor and very low systemic concentrations. With this next-generation oncolytic virus, we hope to demonstrate that we can increase the antitumor activity without exposing patients to unnecessary adverse events," added Dr. Maud Brandely, MD, PhD, Chief Medical Officer of Transgene.

Upcoming presentations on BT-001 include:

1. Poster presentation at the Immuno-Oncology (IO) Summit Europe, March 9-12, 2020, London (UK)

– "BT-001, an oncolytic Vaccinia virus armed with a Treg-depletion-optimized recombinant human anti- CTLA4 antibody and GM-CSF to target the tumor microenvironment" presented by Jean-Baptiste Marchand (Transgene).
